Our refrigeration equipment market has great potential for industrial production of refrigerated transport all food is cooked must be a "cooling" part of this process. And we are currently cooling retort foods be divided into: (1) Indoor sharing cool; (2) forced air cooling; (3) water-cooled sealed bags; (4) flowing rapidly cooled (frozen). We all know that in the above (1) (2) two cooling methods exist several problems: a, long cooling time; b, after cooling, the food surface and core large temperature difference; c, airborne bacteria and dust pole easily attached to the surface of the food cold chain Shenyang-large fruit and vegetable preservation vehicle, and (3) (4) two cooling methods, cooling rate, although relatively (1) (2) fast, but there is still more prominently food surface and core temperature difference between much of a problem, and, flowing speed cold (frozen) means a large amount of equipment investment due to freezing Shenyang-large refrigerator cold chain refrigeration, and when used, and there is so that we deeply troublesome is the problem of frost , so that does not really been adopted by the majority of cooked food production enterprises. How maintenance refrigerated trucks? Refrigerated vehicles as special vehicles before driving are a few things must be noted that, to prevent produce some unnecessary trouble Shenyang-large refrigerated trucks unit cold chain in traffic on the way, before the cargo is loaded with every proposal check the following: 1. Refrigerated Car Fuel diesel or petrol supply must be sufficient to ensure that the engine is running at least until the next checkpoint. 2. refrigerated trucks engine oil engine oil level supply (full) mark, do not refuel excess (replaced once a year). 3. refrigerated trucks Coolant Check the coolant level gauge to see whether the correct amount of coolant Shenyang-large cold chain, the pointer should be in the range of white. If the coolant level in the red range, to be added to the coolant tank coolant. Usually a mixture of ethylene glycol coolant and water (based on availability of product to use in different proportions), and should provide protection to -34 ℃ when not frozen. Note: When the coolant hot, do not open the coolant tank lid.
