Computer and manufacturing Computer aided manufacturing Computer aided mixing Computer and monitoring (2 marks)
STARTER
To know what CAD CAM is and how it is used in the food industry.
To understand the advantages and disadvantages of CAM in food production.
To understand batch, automated, continuous flow and job production.
To be able to answer exam style questions in preparation for the exam.
OBJECTIVES
Designers of food products can prepare 2 or 3D models of new food products and send it across the office or world.
Changes to the products can be made on screen.
Packaging can be designed on screen
How CAD benefits the food industry
COMPUTER AIDED MANUFACTURE
The manufacture of products can involve the use of computers to control one or more aspect of production.
What CAM
Regulate oven thermostats Oven temperature Weighing and measuring The speed /rate at which an ingredient is
added. The amount of mixture/or coating The timing of
mixing/Kneading/stirring/combining.
Examples of CAM
CAM can control the moisture content or PH of a product.
The speed of a conveyer belt. It might detect any colour change e.g over
or under cooked. Example of a thin sauce detecting light ,
sets off alarm. Detect the temp of fridges/freezers Metal detect and an alarm would stop the
line.
What is CAD and CAM give 5 ways of how it can be used in industry. (5)
Get your partner to check your work and tick 5.
Using the two slides write out a definition with 5 points.
1. Detects what the eye cannot see 2. Saves time. 3. Increases speed. 4. Standardises production. (Keeps it the
same) 5. Increases reliability – less mistakes than
by hand. 6. Increases safety of hazardous tasks. 7. Reduces labour costs.
ADVANTAGES OF CAM
Some jobs lost as computers take over. A highly trained operator could run a large section.
It needs programming and computer maintanace.
WHAT DOES THIS MEAN?
The effects of CAM on the industry
Need trained staff to set up computer systems.
Very expensive to set up May reduce the work force causing job loss.
DISADVANTAGES
How manufacturers obtain consistent products: Industrial quality assurance Legal Requirements Quality Control sample CAD/CAM Due diligence
MIX AND MATCH – Look for clues.
Examples of industrial equpiment
Computerized scales Separation process in quorn making
A Centrifuge (Like a spin drier separating liquid from solid in making quorn)
To slice the top off cakes for flat icing.
A Mandolin ( Slices evenly ) A big container to cook soup.
A boiling vat Weighing accurately
Floor standing mixer For consistent mixing
Date stamping To make batches of bread.
A deck oven allows batches to be could at once
Container is filled, sealed and stamped in seconds

ANSWERS
Think about the advantages and disadvantages of CAM. Explain what these are and what are the effects of CAM.
Advantages (3) Disadvantages (3) Effect of CAM for the industry. (2)
Over to you
What do I know and understand?
I Know what CAD is with examples. I know what CAM can do with advantages
and disadvantages. I know the effects on industry.
I have understood examples of large scale equipment.
BRILLIANT!
Automated Production
This is mass production and we have talked loads about this just now. Production that doesn’t stop or need tea-breaks. The effects of this you have written about. CAM is used for this
Recap Safer for workers. More hygienic as less handling of food Assures final quality Accurate measuring/weighing/cutting/shaping/critical
control points are automatically tested and saves time.
Types of production you need to know.
BATCH – production Bakeries on a small scale making a batch of
bread a few dozen buns and not 1000’s.
The equipment can be used for more than one product e.g mixers with dough hooks kneading bread, mixing cake batters.
You need skilled workers.
BATCH PRODUCTION
This is production that goes 24 hours per day 7 days a week. Baked beans, cakes, crisps.
These are machines that have one function only.
They are sold in 1000’s and have a long shelf life.
Continuous flow
This is just like me making a wedding cake. A small bakery might make a special order
cake.
The customer may have special requirements and needs to be very skilled.
One off production
Automated production (CAM) Batch Production Continuous flow production One off production
Give me an example of each? What are the advantages/disadvantages of
each?
What do I know
Method Advantages Disadvantages
Automated flow Can produce 1000’s products safely, hygienically and to a high quality standard.Computerized can record data and set off warning alarms.
Needs expensive programming and maintenance. Whole system may stop.Reduced work force
Batch Can make different variations of batches easily.Can use the same equipment for different items.
Need trained staff
Continuous flow Can produce 1000’s of product accurately, safety and hygienically.
Machinery has only one function. Jobs may be lost.
One off production Can achieve a high quality product.
Time consuming Expensive
