The Dairy industry ranks fifth among the most energy-intensive industries after oil, chemical, pulp, and paper mill, iron and steel. Modern milk processing units employ sophisticated cooling solutions for refrigerating the dairy products. Over 40% of the total electric power consumption in a dairy processing plant goes into the refrigeration application. Hence, energy optimisation in dairy industry’s cooling requirements becomes challenging.
COOLING & HEATING REQUIREMENTS IN DAIRY PROCESSING
ENERGY EFFICIENCY IMPROVEMENT WITH ABSORPTION TECHNOLOGY
BULK MILK COOLING
Replacing conventional Bulk Milk Cooler with Thermax’s Absorption Chiller-Heater solution cools the milk instantly from 35°C to 3.5°C as against conventional bulk milk cooler which takes 4.5 hours. The instant cooling substantially improves the quality of raw milk by minimizing bacterial growth. The same machine (Absorption Chiller-Heater) can be used to generate hot water for cleaning in place (CIP), hence eliminating the need for separate hot water generation system. The Absorption Chiller-Heater leads to higher overall system efficiency due to step-less operation and gives flexibility as the same set up can be used for 5 KL and 10 KL bulk milk cooling.
SMART COLD ROOMS
Replacing conventional ammonia chiller in cold room with Thermax’s Hybrid Absorption Chiller results in substantial power savings of almost 50% with a comparatively smaller footprint.
ENERGY SAVINGS IN CONVENTIONAL RAW MILK CHILLING PLANT
Thermax’s Vapour Absorption Chiller helps to reduce refrigeration load on Ammonia chiller by cooling water from 8°C to 3.5°C. This results in considerable operational savings and energy optimisation.
REPLACING IBT IN RAW MILK PLANT WITH ABSORPTION CHILLER
Replacing conventional IBT (Ice Bank Tank) and Ammonia Chiller system with Thermax’s 1°C Chilled Water Vapour Absorption Chiller gives substantial operational savings. The initial cost also comes down as there is a remarkable reduction in the capacity of (standby) diesel generator.
PASTEURIZATION
Thermax’s Vapour Absorption Chiller-Heater generates chilled water at 1°C & hot water at 85°C simultaneously, which leads to substantial savings in heat input and reduction in cooling tower capacity. The chiller-heater eliminates the dependency on multiple equipment for cooling and heating requirements along with overall reduction in energy costs.
WHY CHILLING OR HEATING OUR WAY?
