Display cooler food controlled atmosphere refrigeration preservation technology

display cooler food control atmosphere refrigeration preservation technology 1) display cooler principle of controlled atmosphere refrigeration preservation The deterioration of fruit and vegetable food mainly comes from their respiration and evaporation, microbial growth, and food composition. Oxidation or browning, etc., and these effects are closely related to the gas in the food storage ...

Modified atmosphere refrigeration and preservation technology of commercial refrigeration food (two)

commercial refrigeration Modified atmosphere refrigeration and preservation technology of food commercial refrigeration rapid oxygen reduction method. This method uses machinery to produce the required artificial gas outside the warehouse and then send it into the cold storage, that is, CA storage, also known as artificial oxygen reduction method . It has two forms: mechanical flushing contr...

Commercial refrigeration cold storage agent and cold storage system (1)

commercial refrigeration cold storage agent and cold storage system 1. Cold storage agent Commercial refrigeration The main cold storage agents are water ice and eutectic ice. Water ice is a pure substance, easy to obtain and environmentally friendly, but its melting point is fixed. eutectic ice has different melting points due to the different types of solutes contained, which can be ad...

display cooler Freeze-drying preservation technology

display cooler Freeze-drying preservation technology After lower temperature requirements, freeze drying is carried out at low temperature and low pressure, so that the ice in the food is sublimated into water vapor to form a dried product obtained from dehydrated food. Since freeze-dried food is of low quality, quick rehydration, good color, aroma and taste, it has an irreplaceable position i...

Commercial refrigeration food vacuum freeze drying

commercial refrigeration food vacuum freeze drying, the food is frozen first, and then dried in a high vacuum chamber. There are generally two freezing methods in commercial refrigeration: automatic method and pre-freezing method. The automatic method is a method that uses the latent heat of vaporization to absorb the latent heat of vaporization when the water in the food evaporates to promote...

Walk-in cooler two-stage compression and cascade refrigeration cycle

walk-in cooler two-stage compression and cascade refrigeration cycle In the walk-in cooler vapor compression refrigeration cycle, when the refrigerant is selected, its condensation pressure , The evaporation pressure is determined by the condensation temperature and the evaporation temperature. The condensation temperature is limited by the temperature of the ambient medium (water or air); the...

display cooler two-stage compression refrigeration cycle

display cooler two-stage compression refrigeration cycle display cooler two-stage compression refrigeration cycle, the refrigerant compression process is carried out in two stages. The low-pressure refrigerant vapor from the evaporator (pressure Po) first enters the low-pressure compressor, where it is compressed to the intermediate pressure Pm, and then enters the high-pressure compressor af...
