An Alternative Option for Milk Cooling-Thermoelectric Cooling-A Review
Author(s): Prakash S.P* and Nithyalakshmi V
Typically milk is chilled by using refrigeration systems such as bulk milk cooler, cold storage, cooling
rings, surface coolers ice cones, ice bank cooling, direct expansion cooling which is not cost effective
and energy effective as it involves bulky piping and mechanical compressors. This refrigeration system
produces a cooling effect by using refrigerants like freon, ammonia, etc., which leads to global
warming and also these systems are not reliable and economical, where compact design and noiseless
operation is required. Existing cooling methods are only suitable for cooling large quantity of milk and
it is also uneconomical to use for small holder dairy farms. To overcome these problems (small
quantity milk producer, delayed milk cooling and global warming due to refrigerants), there is a need
for energy efficient, green and eco-friendly technologies to c.. View More»
