“In order to contribute to the availability of food for a constantly growing population, demanding with the quality of the products of the meat industry" Meat becomes an ideal culture medium for the growth of almost any micro-organism. This is due to its nutritional qualities, neutral post-mortem pH (pH = 6.5), high water activity (aw = 0.98), and extrinsic factors such as temperature and oxygen concentration. Meat and meat products are perishable by nature and easily susceptible to microbial contamination and chemical...

Defrost Process – Part two

Air defrosting In refrigeration, air defrost is an effective method of combating ice build-up in evaporators. This process uses the air in the chamber itself to defrost the frost efficiently. Its suitability is intensified in chambers above 4ºC, as at lower temperatures its effectiveness is reduced. The system starts with the closing of the liquid solenoid valve, which stops the refrigerant flow to the evaporator and to be emptied by the compressor until it stops. In this case the fans recirculate the air...
