HERITAGE FOODS LIMITED
Hyderabad (Telangana)
Unit Profile
Hertage Foods Limited, Uppal Dairy Plant Commissioned in the year 2006 with a
rated capacity of 0.6 LLPD and was subsequently expanded to 0.74 LLPD in 2007,
1.1 LLPD in 2010 and 1.5 LLPD in 2012.
Presently, Heritage Milk and Milk Products have market presence in Andhra Pradesh,
Telangana, Karnataka, Tamilnadu, Kerala, Maharashtra, Odisha and Delhi.
Energy Consumption
Energy is the biggest component of the operational costs in the Dairy Industry. The
Unit has taken this as a challenge to reduce its energy cost. The energy
conservation drive got a good momentum when the Unit declared Energy
Management Policy in 2012.
Description Unit 2012-13 2013-14 % Reduction
Specific Electrical Energy kWh/Ton 61.99 48.25 22.17
Specific Thermal energy million kCal/Ton 0.05921 0.05289 10.67

Energy Conservation Measures Taken
1. Installation of Ammonia Chiller
Ammonia chiller installed in return chilled water
line from processing to reduce the temperature
by 3 °C which reduces the load on IBT (PHE
system of cooling is more effective as the
ammonia and return chilled water passes
through plate by plate which increases the
contact surface tremendously and leads to
instant exchange of heat).
Electricity saving : 2.409 Lakh kWh/yr
Cost saving : Rs 19.36 Lakh/yr
2. Centrifuge for installation for Oil fired Boiler
Centrifuge has been installed for Pre-Filtration of
furnace oil to Boiler which ultimately reduced
nozzle choking and efficiency of Burner have
been improved.
The steam generation per liter of Furnace Oil
have been improved which saved an annual of
7% of Furnace Oil.
Furnace Oil saving : 16.74 kL/yr
Cost saving : Rs. 8.41 Lakh/yr

3. Installation of Pre-Heater for pre-heating the Curd Milk
Pre heating of curd milk with OHT soft water has
double impact both on FO & Electrical energy.
Due to preheating the inlet temp. of curd milk to
the curd past. Increased to 17 °C against 5 °C
which saves 8.46 kL of Furnace oil.
On the other hand the OHT soft water cooled to
15 °C which used in RSM (Reconstitution
skimmed milk) preparation and in cream past for cooling cream after regeneration.
Electricity savings : 0.401 Lakh kWh/yr
FO saving : 8.46 kL/yr
Cost saving : Rs. 7.48 Lakh/yr
4. Arrangement of Cyclic timers for Milk silo agitator motors
15 nos. of Cyclic timers were arranged for
packing milk Silo’s for operating with cyclic
intervals of 10 minutes span with which we can
save electricity of 161 Units per day.
Agitator running hrs per day has been reduced.
Maintenance cost also reduced accordingly.
Electricity savings : 0.57 Lakh kWh/yr
Cost saving : Rs. 4.65 Lakh/yr
5. Downsizing of ETP Air blower pulleys
Due to water conservation measures and GMP
practices implemented, the water quantity and
COD reduced by 25% & 38% respectively. As
dissolve oxygen in aeration tank is found more,
the blower pully has down sized, which results
in reduction of RPM of Blower.
With the above modifications the electricty
consumption was reduced by 21%.
Electricity savings : Rs. 0.401 Lakh kWh/yr
Cost saving : Rs 3.22 Lakh/yr

6. Condensate recovery from CIP Tanks
In CIP section the direct steam injection to
generate hot water is replaced with SS pumpkin
type coils.
Due to this the heating time reduced to half and
the collected condensate is used as a boiler feed
water.
Furnace oil savings : 8.10 kL/yr
Cost saving : Rs 4.07 Lakh/yr
ENERGY POLICY
The Unit is committed in Energy Management Performance on a continual basis
through
• Continuous up gradation of technology, systems and service to optimize the
energy cost.
• Monitor and control the Energy consumption effectively.
• Providing Resources to achieve measurable objectives whenever necessary.
• Educate and motivate all the people concerned through effective
communication and recognition
• From time to time identify the energy saving potential for reduction of energy
consumption.
• Conducting energy conservational studies & energy audits through internal &
external professional.
• To Establish bench mark Energy standards in dairy industry.

SURAT DISTRICT CO-OPERATIVE MILK PRODUCERS
UNION LIMITED, SUMUL DAIRY
Surat (Gujarat)
Unit Profile
Surat District has been a Pioneer in India in channeling trade in Cotton and
Milk through co-operatives. Before SUMUL stepped in, traditional Private Milk
Traders were dominant in the area. Dairying on the other hand, was never
popular with tribal (a major rural population in the district) as practically no
infrastructure existed for milk marketing in their talukas, inaccessibility to their
villages as well as taboos regarding keeping of buffaloes prevented the entire
population of tribal from considering dairying as a source of income. To salvage the
poor producers from the clutches of these Private Traders, Organization and
integration of procurement, processing and marketing of milk and milk products by
the producers themselves on a sound co-operative line was essential; this would
also ensure elimination of middlemen, equitable distribution of benefits to Rural Milk
Producers and indirectly to urban milk consumers as well. Being a producers owned
organization, it eliminated the middlemen and minimized the overhead costs giving
the maximum overall net-returns to its producer members from their milk
production enterprises.
