Cooling refrigeration equipment cooling refrigeration equipment has both direct and indirect cooling. Direct cooling refrigerator evaporator is mounted in the housing or building refrigerating apparatus using a refrigerant evaporator wherein the direct cooling air vegetables fresh car, the cold air cooled by the cooling needs of the object. The advantage of this cooling method is cooling fast, small temperature difference, the system is relatively simple, and thus been widely used. Indirect cooling refrigerator evaporator is evaporated by the refrigerant, so that the secondary refrigerant (e.g., saline) was cooled, and then enter the secondary refrigerant refrigerating apparatus housing or the building, through a heat exchanger to cool the air therein. This cooling method of cooling is slow, the overall heat transfer temperature difference, the system is more complex, it is only for the few occasions, such as saline ice and cold storage and other constant temperature requirements. Our refrigeration equipment market has great potential for industrial production of refrigerated transport all food is cooked must be a "cooling" This technology links. And our current high-temperature cooking of food Cooling roughly divided into: (1) indoor stalls cool; (2) forced air cooling; (3) water-cooled sealed bags; (4) the flow velocity cold state (frozen). We all know that the above (1) (2) there are two ways of cooling the following questions: a, long cooling time; b, after cooling, food larger temperature difference between the surface and the core; c, airborne bacteria and dust pole easily attached to the surface of the food preservation car prices, and (3) (4) of two cooling, cooling rate, although relatively (1) (2) faster, but there is still more prominently food temperature difference between the surface and the core of much of Problem fresh milk truck, and, flow pattern speed cold (freezing) devices due to refrigeration equipment investment is large, but when used, but also so that we feel there is a headache problem of frost, so not really the majority of cooked food manufacturers used.
