AFREM'S “DRYING EXPERTISE”

2

DRYING, A SUBTLE PROCESSThe drying operation is a transformation that is found inmany industrial sectors : food processing, paper making, phar-maceutical processing, chemicalmanufacturing, etc.Drying occurs when a product isheated sufficiently to cause evaporation of the liquid compo-nents (water or other solvents),without affecting the functionalproperties of the raw materials,while conserving the results ofprior processes applied and ensuring compliance with thequality criteria for the finished product. Attention and adherenceto these criteria make this transformation such a subtle one.

The liquid extraction processenables us to :

lengthen product life,give products specific final textural and structural properties,reduce transport costs,facilitate subsequent handling and transformations.

EACH PRODUCT HAS A UNIQUE PROCESSThe drying techniques utilizeddepend on the shape or the physical state of the products tobe dried : whether they are inliquid, solid, powder or pastyform. Water loss kinetics for aliquid product are simple, because the drying speed isconstant. The situation is verydifferent for solid products, inwhich water may be present in 3 forms : free, absorbed andcombined.

free water is easily removed from a solidabsorbed water may be remo-ved by applying a certain quantity of energywhereas it is impossible to remove water that is chemically combinedwithout modifying the intrinsic structure of the solid

UNDERSTANDING, DESIGNING, MANUFACTURING :AFREM’S SKILLS To design a dryer that suits yourindividual requirements, we takea wide range of data into account :

choice of the drying technology that best suits the product, by examining the criteria of quality, cost efficiency and preservationof the environment.industrial sizing :this integrates the heatbalances, the mass and heattransfer laws, the shape, sizeand density of the product, the production output rate and control of the water contentat the input and output.acquisition of the productcharacteristics : heat sensitivity and drying speed.

As drying mechanisms are notentirely predictable,it is necessary to go through a small-scale experimentalphase to determine the water loss kinetics.

Experimentation is a key stagein the development of new products : utilizing standardplatforms, the equipment is specifically adapted to suit yourrequirements. In this approach,AFREM accompanies you in thetask of designing and developingyour products and processes.

AFREM has pilot systems available that simulate varioustypes of heat treatment. Thesetests can be carried out to :

validate technological feasibilitydetermine industrial sizingidentify the "product - process"critical points transfer experimental layoutsinto industrial environmentsensure process control before transfer to the production site.

The CLEXTRAL Group has amulti-purpose pilot plant at itsdisposal, which integrates AFREMdryers :

batch dryer : the AFREM drying oven. This pilot unit can be used to simulate seve-ral drying technologies :

- static drying on fixed frames and rods

- dynamic drying in a drum

continuous dryer : the CDS(Compact Drying System). As its name suggests, it is a compact drying line, with integrated steam kits, that includes a vibrating skin dryer, a twin-cage rotary dryer and a cooler.

AFREM : YOUR DRYING PARTNERAFREM equipment, expertly desi-gned to suit specific user require-ments, is supplied on a turnkeybasis. Our offer includes produc-tion expertise, superior productquality and network of partners,making AFREM an ideal choicefor your drying requirements.

PILOT PLANTS : WORKING IN CLEXTRAL’S FACILITIES TO INNOVATE AND INVENTTOMORROW’S PRODUCTSCreativity, dynamics, partnerships :key assets to ensure progress for our customers.

TOMORROW’S PRODUCTS

Two pilot plants at our customers’ service

CLEXTRAL operatestwo test centres,one in France and the other in the USA ; they are indispensable toolsfor the developmentand creation ofnew products.

A global approachworks best when

consideration is given to one customer at a time. CLEXTRALremains close to our customers inall aspects of service, particularlyin process support. For this reason,both pilot plants work on a sharedplatform, the Evolum® 53 twinscrew extruder. This enables ourinternational customers to test anidea and conduct developmentwork in one region, then transferthat expertise to a local productionfacility on another continent whileminimizing logistical concerns such

as transport and import of rawmaterials.

Of course, equipment constitutes amajor parameter because it ensuresmaximum efficiency in developmentwork, and for this reason CLEXTRALmaintains an aggressive investmentpolicy for its pilot plant facilities.Our fully-equipped centres offer atotal of nine twin-screw extruderstogether with dryers, mixers, a flaker, etc., and a large number ofauxilliary elements. This equipmentmay be used to carry out work oncomplete units for CLEXTRAL’s different fields of activity : extrusionof food products, plastics, paperpulp, pasta, couscous, etc.

However, the keystone of the orga-nization is the multidisciplinaryteam of engineers and technicianswith diverse training and experience,who bring together scientific disciplines and practical knowledge.CLEXTRAL’s teams regularly travelaround the world, visiting our partners’ sites, implementing newconcepts and learning about production issues in our customer’sand partners’ factories. The endpurpose of their creative workremains firmly oriented towardsindustrialization.

Test Centre Utilization

The CLEXTRAL test stations aremultipurpose : they are utilized forthe firm’s research and developmentwork and its sales and marketingefforts.

Internal test centres

CLEXTRAL’S internal test centresare dedicated to technologicaladvancements. Before new equip-ment designs are brought to themarket, the prototypes undergostrict test programmes to checktheir functionalities and theirrobustness, in conformity with ISO9001 quality standards. For examplethis has been the case in recentyears for Evolum® extruders, andalso for the new compact dryer(CDS : Compact Drying System) forpellets and pasta, which is current-ly installed in the european test centre.

It is also in CLEXTRAL’s test centresin Firminy and Tampa that tomor-row’s products are pro-actively created, whether they take theform of improvements to existingproduct families, such as newshapes or textures for breakfastcereals ; integration of functionalingredients ; or more advanceddevelopments like the recent workon protein fibration units (HMEC :High Moisture Extrusion Cooking).

Over the decades, the growth anddevelopment of CLEXTRAL hasbeen marked by innovation andtechnological advances, including :

multiple colouring systemsthat enable different shapesand colours to be producedsimultaneously,

Every year, the CLEXTRAL groupapplies for many patents linked toequipment, processes, and finishedproducts.

PLATFORM FOR CUSTOMER TESTS Whether in Tampa or in Firminy,many customers from all over theworld visit CLEXTRAL each week to :

attend demonstrations concerning processes or technology, participate to one-week trainingmodules that are designed for operators, maintenancestaff, and process managers.Each module is customizeddepending on the specificdemand, and conducted by an experienced engineer to ensure complete understanding of the CLEXTRALextruder, take part in a seminar dedicated to a specific industry.

Every day, our customers’ ideas aretested on our extrusion units. Eachtest is rigorously documented byone of our experts, in accordancewith ISO 9001 standards. The testfile is the central record thatenables full preparation of thetests, and it also covers the aspects

of confidentiality and intellectualproperty.

CUSTOMER PARTNERSHIPS Moving beyond these classicapproaches, CLEXTRAL regularlyinitiates closer partnerships withcustomers ; which take many forms.

Joint R&D programmes are truejoint development ventures, whichrespect the expertise and contribu-tions of each partner (especially asfar as intellectual property and confidentiality are concerned).These programmes form a basis forwin-win relationships in which bothparties work together with a clearlydefined common goal, mixing theirteams to ensure maximum levels ofefficiency.

Some programmes use dedicatedtechnology platforms set up inFrance or in the USA to provide ourpartners with faster access to ourtest centres, with additional periph-eral equipment already on site, andthe option to store raw materialsand finished products as well. Ourpartners have complete access totechnical experts who are fully conversant in their technologies,ensuring a truly productive relationship.

Test production runs are performedto meet orders from our customers,enabling them to validate their marketing hypotheses at full scale,without investing in a productionunit immediately, or contacting aco-packer, with the resulting obligation of revealing specificknow how and divulgate someintellectual property.

CLEXTRAL is actively participatingin the development of new productsand services to support our customers around the world,through investments in personnel(technicians, engineers, doctors)and technology (new machinedesigns and improvements). 5 to 7 %of annual income is invested inresearch and development.

TO KNOW A LOT ABOUT SUGAR

6

Sugar (or saccharose for the chemists), a symbol of pleasure and well-being, has a tumultuous, fascinating history : the product, which was formerly an object of envy, linked to adventure and great explorations, is now consumed throughout the world at a rate of over 128 million tonnes per year !

SOME HISTORY…Sugar cane was certainly grown inNew Guinea 3,000 years ago ; it wastransported to India, and then on toChina. The name comes from theSanskrit word “Sarkara”, whichgave the words : sucre, Zucker,sugar, zucchero, azucar, etc.It was not until 15 centuries later,i.e. in about 500 B.C., that thePersians (Iran) grew sugar cane toextract “this honey without bees”.Just two hundred years later, theexotic plant was being grownthroughout the Mediterraneanbasin, thanks to the Arab conquerors. The crusades helpedto spread it to the countries ofNorthern Europe.

cooling, that stabilizes the product, gives it a certainviscosity, and makes it suitablefor subsequent treatment : shaping, pouring, cutting, etc.

Twin-screw cooking and extrusionwas invented by CLEXTRAL in the1970s for applications in the FoodIndustry : the phases outlinedabove are exactly the same functions as those provided by atwin-screw machine : it was thusquite logical for CLEXTRAL to takean interest in these processes. Apatent was taken out in 1973 underthe number 73 46887, with thetheme : manufacturing process fordecrystallized sugar.This innovative technology hassince been used to improve existingprocesses and create new products.

APPLICATIONSThere are many applications inconfectionery that use the twin-screw technology includingthe following examples :

continuous conching of chocolate, production of cooked amorphous sugar, chewing gum and continuousproduction of gum base,hard and soft liquorice, almond paste and marzipan,jellied sweets,caramel and caramelized milk(“dulce de leche”)jelly fruit

Thanks to its exceptional charac-teristics, the CLEXTRAL co-rotatingtwin-screw machine is able to process all these widely differingproducts, continuously, as it

Explorers and traders from Italy,Spain and especially Portugal, followed by the English and theFrench, carried sugar cane withthem to grow it in Brazil and theWest Indies. Sugar beet was not grown until the19th century.

In Europe, we eat about 35 kg ofsugar per person each year, eitherdirectly, or indirectly (about 3/4 ofthe total) included in manufacturedfood and foodservice products.The chemical and pharmaceuticalindustries only use a small fractionof the overall quantities.Certain countries such as Australia,Cuba, Israel, etc., show record levels of consumption, withamounts of over 55 kg per personeach year, and as high as 67 kg perperson each year in Singapore.

PRODUCTS AND THE COOKING/EXTRUSIONPROCESS To find pleasant ways to satisfy histaste buds, mankind has inventedvast quantities of products basedon sugar. The traditional manufac-turing technology usually involvesseveral successive phases, whichare usually :

mixing : sugar + additives(polymers, functionalingredients) + water,cooking during which the crystals disappear ; a smooth, homogenous,mixture is produced,tastes and aromas are developed, and the water content is reduced throughcontrolled evaporation,

and an infinite variety of recipes,flexibility of use that makes it easy to switch from one product to another.

combines several basic functionssuch as : mixing, heating/cooking,degassing, cooling, and shaping.

The generic process is as follows :

The crystallized sugar is dosed inthe feeder section of the machine,with one or more ingredients suchas : starch, wheat flour, glucosesyrup, fat, molasses, fruit concen-trate, etc. : a mixture is producedinside the machine with initialexternal heating and shearing provided by the screw.In the following section, the mixture is cooked, stirred, sheared,and homogenized, and transformedinto a paste : this is the plasticizationsection. Next, the mixture may be allowedto degaze, and/or receive othersolid ingredients. As the product istransported, its temperature is controlled : other functional ingre-dients are injected, such asflavours, fluidizers, or gellingagents, for example, and the product is mixed continuously toobtain a homogenous product. Once it has reached a certain viscosity, the product is compressedand then extruded through ashaped die. Some products aresolid enough to be cut directly asthey exit the machine, while othersrequire a waiting period after extrusion before they can bepoured into moulds or put ontocooling belts, and then given theirfinal shape.

To meet these generic requirements,CLEXTRAL provides the followingelements with its extrusion systems :

thorough knowledge of the processes and full mastery of complete lines,expertise concerning the composition of the screws(made up of different elements)

a screw length/diameter (L/D)ratio of between 25 and 48,high heating and cooling capacities,a machine able to operate at low or high speeds, with sufficient spare motortorque and capacity to absorb high pressure levels, mastery of metallurgy for the screws and barrels, to ensure compatibility with the products transformedand the mechanical forces involved,a design that enables easy control, maintenance and cleaning.

The main advantages of this technology are as follows :

a continuous process that replaces several discontinuous operations : the startup, shutdown, controland automation phases are optimized. This facilitatestraceability considerably.a compact technologythat conserves floorspace, and reduced pro-duction costs concerningmaintenance, power,staff, and investment.Often, when the productexits the extruder, it has reached its final moisturelevel of conservation ;this eliminates drying phasesthat can last several hours (or days), a guarantee of constant qualityunder highly favourable conditions of hygiene,all types of materials may be processed because the twin-screw machine does nothave any limitations in terms ofviscosity, an immediate, advan-tageous capacity for innovation,

PULP FROM COTTON LINTERS :PROCESS WICH CANNOT BE MISSED

linters of poor quality, which may contain over 30 % miscellaneous waste.a process ensuring a high level and constantpulp quality with less labor,a pulp quality that enablesthe production of writing and printing paper conformingto the highest internationalstandards,reduced quantities of chemical reagents ; the savings on reagents can reach 20 to 30 %,a bleaching process that preserves the quality of the environment by usingonly hydrogen peroxide as a bleaching agent, and provides pulp that has been bleachedwithout chlorinated agents,i.e. TCF pulp, a manufacturing process that is well suited for use in countries with limitedwater resources, as the process requires only small amount of water ;water savings can be as highas 90 % as compared with traditional processes, major savings of electricaland thermal energy representing up to 30 % of the total energy requirements,because the process does notuse steam, unlike traditionalprocesses,substantial savings on civilengineering due to compactsize of the equipment equipment designed for easy maintenance.

Cotton linters :

Cotton linters are agriculturalresidues from cotton crops thatrepresent a highly advantageoussource of cellulose for makingquality paper.

These raw materials, whose qualitycan vary widely depending ontheir geographical origin and theharvesting techniques used locally,may be processed to obtainpaper pulp and then paper whosefinal quality and applications arevery different.

A patented, continuous process :

Significant advantages :

The twin-screw process offersimportant benefits for our customers :

the ability to process cottonlinters of widely varying quality, particularly cotton

CLEXTRAL provides simple, optimized, cost-effective solutions for producing paper pulp from annual plants. Converting cotton linters into paper pulp is one of many processes developed by CLEXTRAL that create opportunities for cotton-producing regionsand for countries manufacturing high-quality paper and specialty papers.

Many applications for paper pulp made with cotton linters :

Among the many applications arespecialty papers with high addedvalue, such as security paper, drawing paper and filter paper.Another market is high-qualityprinting and writing paper that ismanufactured to meet the localrequirements of the cotton producing countries. Concerningthis application, the value addedto local raw materials representssubstantial currency savings forthese countries, as most importpulp or paper for domestic consumption.

An economical process :

The table below shows the costefficiency of pulp productionusing cotton linters pulping process developed by CLEXTRAL.

Considerable experience :

The CLEXTRAL process to convert cotton fibres into pulp,based on the TWIN-SCREWmachine, has been in continuoususe for over 15 years. Units thatmanufacture pulp from cottonfibres, including cotton linters,are currently in operation to thesatisfaction of our customers inmany countries, includingFrance, Great Britain, Russia,China, Zimbabwe and morerecently, Uzbekistan.Operation of these productionunits proved that the process is

especially well suited for small tomedium levels of capacity, i.e.between 2,000 and 20,000 tonnesper year. Furthermore, our experience now enables us to provide simplified equipment

and production unitsthat generate enor-mous savings in overall investmentsand operating costs.

A more competitiveprocess :

Thanks to extensivefield experience andcollaboration withcustomers, CLEXTRALhas completed studiesthat resulted in simpler, more eco-nomical twin-screwmachines. The newtwin-screw machineis called the EVOLUM240 PAP. Moreover,the work to ensuresimplification hasbeen extended to

cover the whole pulp manufac-turing process. Today, we canprovide equipment and produc-tion units at prices that are 20 to25 % lower than the previousmodels.CLEXTRAL has also concentratedon reducing operating costs morespecifically the maintenancecosts of the twin-screw machines.Changes have been made in thegeometry of the wear parts,together with new metallurgicalsolutions that are less costly andensure longer service life, reducing maintenance costs byover 40 %.

DKM, CLEXTRAL’S DOSING AND TRANSFER PUMP DIVISION IS WELL-KNOWN FOR ITS EXPERTISE IN THE FIELD OF ENERGY

DKM is especially active in the treatment of fossilized energy,petroleum, usually at the wellheadlevel.When crude oil comes out of theground, it is very often a mixtureof gas and liquid, sometimes withadded water (seawater in offshorewells), so it cannot flow directlythrough pipelines thousands ofkilometres long to reach the usercountries and their refineries.Gas-liquid separation and chemicaltreatment units are located onthe spot or nearby.By definition, for a well to beefficient, the petroleum mustemerge under pressure. Atfirst, the pressure is creatednaturally, by the weight of the Earth’s strata above theoil-bearing layer. As thepetroleum is removed, thepressure falls and artificialmethods are used to increaseit. One common methodinvolves re-injecting gas underpressure alongside the well pipe in the Gas Lift system.When the oil reaches groundlevel, naturally, there is a pressuredrop, and just as in a refrigerator,there is a risk of frosting on thevalves and piping on the“Christmas tree”. This is where

DKM’s expertise and equipmentis essential.DKM systems inject small quantitiesof methanol under high pressure(equal to that of the well) to prevent frosting, either in the GasLift system, or at the level of thewellhead. The output levels are afew dozen litres per hour, at 150to 450 bars. DKM pumps may alsoinject other products at the levelof the well including anti-foamingagents, bactericides and corrosioninhibitors (because the pipelinesare made of carbon steel.)DKM also supplies circulationpumps for hot glycol to dry thegas, if it is not re-injected into theoil-bearing rock.In certain cases, DKM pumps areused to inject emulsions that freethe crude oil from the porousrock and thus ensure the recoveryof the full contents of the oilfields.

Far from the wells, and muchcloser to us in artificial under-ground gas storage sites, DKMpumps inject methanol to prevent frosting when large quan-tities of gas are taken out duringthe winter. They are utilized todose a powerful odorant, tetrahy-

drothiophene, into natural gas,increasing safety by enabling thedetection of leaks. Finally,petroleum companies utilize DKMpumps to dose various additivesinto fuels leaving their refineriesbefore being sold to the generalpublic.

There are almost 2,000 DKMpumps in service in the mainpetroleum producing areas, mainlyin the Russian Federation, Iran,and Qatar, and around the Gulf ofGuinea : Congo, Nigeria, andAngola.

In the field of nuclear energy,DKM supplies a specific type ofpump, used in each PWR typenuclear power station in Franceand in other countries: SouthAfrica, Korea, and China.

This multi-purpose pump is usedto test the primary circuits(seals, valve operation, etc.),to fill the accumulators, and asan emergency backup to lubri-cate the primary pump seals,in the event of a total powerfailure in the power station.55 pumps of this type, qualified to operate duringand after a severe earthquake,have been delivered for 900 MW, 1,300 MW and 1,400MW power stations.

DKM technology is also used inthe chemical refining processesfor spent nuclear fuel.

Its expertise and its full masteryof the processes involved enableDKM to provide innovative, reliable solutions in sectors ofextreme technical complexity.

It has become a traditionfor LYMAC : one innovationreplaces another.Following the successof the COMBI-PACK(see Clextrusion N°11)comes the debut of the compact TFC-220 vertical bagger, which can form various bag dimensions, including the shape known as the“squaretop and bottom” shape.

What is a square top and bottom bag ?

It is a bag whosesquare base is self-supporting. The headis given the sameshape with a weldthat is folded downand bonded.This geometry makes the bagseasy to handle and store, andenables attractive shelf presenta-tion.

Technology

Two machines are usuallyrequired to make this kind of bag :first, a “standard” bagger, andthen a carousel to finish the folding and bonding operationson the upper section.Yet the LYMAC TFC-220 baggercan complete all the operations,in one machine, functioning in acascade sequence.

First, the machine makes the bagwith a square bottom and a gusset top. After filling, the bag is Number 12 - December 2004
