Energy Efficiency in the Food Processing Industry

The food processing industry is a vast and diverse industry comprising of various divisions. They include dairy products, fruits, vegetables, fish, meat, oils, packaged foods, bakery products, and beverages. The three main factors that decide the energy usage in the food processing industry are lighting, air conditioning and good ventilation. It is vital to keep the temperature under control so that the food and beverages stay fresh and unspoiled.

Thermal processing, dehydration, process heating, cooling and refrigeration in food processing require a lot of energy. Energy is used for food preservation, hygienic and safe packing, and storage, adhering strictly to industry norms. Converting raw materials to products which involve heating, cooling, drying and refrigeration calls for manpower and mechanical energy. Proper storage consumes a great deal of fossil fuel and electric energy as in cooling, drying and freezing. The other energy guzzlers are lighting, heating, ventilation, air conditioning, and transportation.
