Vacuum pre -cooler is a vacuum pre -cold technology, using vacuum pumps to extract air and water vapor in vacuum tanks to reduce the cooling processing equipment in the vacuum box.Under low pressure, the boiling point of the water decreases, the evaporation potential heat increases, and the spontaneous vaporization of the surface of the cooling object will take away the heat of itself and the bad realm to achieve the cooling and cooling effect.
Principles of vacuum pre -cold machine
The principle of vacuum pre -cooler is under a standard atmosphere. The boiling point of the water is 100 ° C, and the evaporation heat is 2256.69kj/kg; and when the pressure is reduced to 613Pa, the boiling point of the water is 0 ° C, and the evaporation heat is 2499.52kj/kg, and followsThe pressure of the boiling point of the water also decreased, and the heat consumed by the quality water consumed by the evaporation unit increased.The principle of vacuum cooling technology is to place the cowhide produced in the vacuum cooling room of the cooling fruits and vegetables, cooked foods, and extract air through the vacuum pump to create a low -pressure environment to evaporate the water inside the product; because the evaporation process is accompanied by heat absorption, the evaporation process is accompanied by heat absorption, and the heat absorption is accompanied by heat absorption.The temperature of the evaporation itself decreases.
Vacuum pre -cooler price
The price of vacuum pre-cooler is 100,000-300,000 yuan per unit.Features of vacuum pre-cold machine: 1. Cooling speed fast: 20-30 minutes can reach the required refrigerator temperature.2. Uniform cooling: The surface of the product is free to take away its own heat to achieve the cooling purpose of cooling, and achieve uniform cooling from the inside out.3. Clean hygiene: Under a bad vacuum, it can sterilize or inhibit bacterial reproduction and prevent cross -pollution.4. Thin layer drying effect: It has unique effects such as cure epithelial damage or inhibitory expansion.
