Fresh vegetables, vegetable vacuum cooling machine vacuum cooling machine vacuum cooling machine prices of fresh vegetables vegetables fresh vegetables vacuum rapid cooling machine vacuum cooling machine manufacturers Shanghai steel engine cooked food, fruit fast techology: 021-51217879 or 18918967075 fresh vegetables vacuum preloading Cooler, that vacuum cooling machine. In the industry is divided into two categories: food type vacuum cooling machine vacuum cooling machine fruits and vegetables. The former is hot cooked quickly and efficiently cooled from a high temperature (85 ℃ -90 ℃) to less than 15 ℃, which is the fruit, vegetables rapidly cooled to refrigeration temperatures to remove field heat. March 2, according to Shanghai steel engine Products Division said, vacuum cooling machine in food preservation performance cooling and cold storage facilities representing a qualitative leap! Why vacuum cooling machine cooling food very fast? Vacuum rapid cooling machine cooling medium is water, changing the water also has two parts: the food attached to the surface of water, food and internal composition of the water. Vacuum cooling machine vacuum box, and the box to maintain a certain vacuum state. The pressure of the water at the surface of changed conditions, the boiling point changes abruptly, when the water surface in the 0.6 atm pressure, a boiling point of 0 ℃; and, the water directly from the liquid into a gaseous process phase with the change, will take away a lot of heat, water directly into the liquid from the liquid process is called vaporization - According to scientific estimates, the same quality of water in completely vaporized liquid is elevated heat needed 1 ℃ 575 times. In addition, the vacuum cooling machine to be cooled food surface to create a vacuum environment, the cooling medium is water, the water vaporized during its evaporation channel has been opened, the food inside to the surface direction of the heat radiated from the core, high heat exchange efficiency. Thus, vacuum cooling machine cooling food is fast. Why advantageous vacuum cooling machine cooling food preservation it? As described above, vacuum cooling machine cooling medium is water food, with water evaporation channel has been opened, the core is cooled food to quickly distribute the heat so that the food does not heat the interior of the core and avoid prolonged accumulation " boring ", so as to maintain the color of the food to be cooled, fresh taste to avoid prolonged high temperature heat accumulation within the food so that the composition of the food inside cells to destroy the nutrients. Thus, vacuum cooling machine cooling food is fresh packaging front-end processing, high temperature and other food cooked by vacuum cooling machine to cool more favorable preservation. Fresh vegetables vacuum cooling machine for the first time for fast pre-cooling of fruits and vegetables fresh organic vegetables the best technology and other high temperature in summer weather, field heat is a key factor affecting vegetable freshness. At present, China's large-scale vegetable bases basic vacuum fast pre-cooling device, after picking vegetables, fruits, and fruit for the first time for fast pre-cooling, and then deliver refrigerated cold chain, transportation and sales. Fresh vegetables vacuum cooling machine, the main role is to be cooled cooked rapid cooling, rapid avoid easy to breed, such as temperature with E. coli and other harmful bacteria (30 ℃ -60 ℃), suppress some of the harmful bacteria and reproduction, played preservation role. Fresh vegetables vacuum cooling machine a central role in the food production process, cooked food at 30 ℃ -60 ℃ place longer, its fermentation and bacteria faster, which would lead to food spoilage and decay accelerated, shortening the shelf life of food products (shelf life). Vacuum cooling is cooked fast food industry is more advanced cooling technology, she can effectively address these problems. Fresh vegetables, fruit and vegetable vacuum cooling machine, hot cooked food preservation, packaging front-end cooling equipment, is currently in Europe and America and other developed countries to solve the high temperature of cooked food preservation, food packaging machinery and equipment indispensable. Due to space limitations, this article on the definition of vacuum cooling machine fresh vegetables, fresh vegetables vacuum cooling machine selection and other contents are described below: fresh vegetables, fresh vegetables type vacuum cooling machine vacuum cooling machine to be treated by different temperature of the food can be divided into fresh fruits and vegetables vacuum cooling machine type (low temperature vacuum cooling machine fresh vegetables), fresh vegetables cooked food vacuum cooling machine (high temperature fresh vegetables vacuum cooling machine). Two types of vegetables fresh vacuum cooling machine vacuum differ in the mechanism, vacuum cooling technology and proportion. In the people of the increasing concern about food hygiene and government regulatory measures for food safety management background of increasing food production and distribution companies need to do a good job from the source of food hygiene, safety management. Tracking the development of our fresh vegetables vacuum cooling machine machine, modified atmosphere packaging and other food preservation equipment because no preservatives, artificial coloring and other chemicals for food preservation, food safety escort. In the vegetable preservation vacuum cooling machine vacuum built-in vacuum pump continued role in the formation of internal and external pressure differential vacuum box. Under this pressure difference, the food inside / outside surface pressure of water molecules greatly reduced. Thus, the water molecules from the liquid into a gaseous form rapidly "heat of vaporization" was continued outside pumping, take away a lot of heat, braised pork and other high-temperature cooked food can be quickly and uniformly cooled. Selection of fresh vegetables, fresh vegetables, vacuum cooling machine vacuum cooling machine can be used to eliminate fruit and vegetable field heat and hot cooked food rapidly cooled to ambient temperature range (T≤15 ℃). Its central role is pre-cooling, pre-cooling for easy packing and placed 0 ℃ -5 ℃ cold storage preservation storage. Selection of fresh vegetables vacuum cooling machine mainly refer to the following: 1, vacuum cabinet volume is the key basis for their selection - food filling cabinet volume density, it is fresh vegetables, a vacuum cooling machine to cool the quality of food. Therefore, different filling density of different foods, the same volume of a vacuum box can cool food quality is different; 2, fresh vegetables are cooled vacuum cooling confidential according to the type of food, its initial temperature differ significantly - cooked food The cooling temperature is usually above 80 ℃, while fruit and vegetable field heat is generally less than 45 ℃, so the temperature difference between them when they were pre-cooled lot of difference, general manufacturers in the model code will be differentiated (such as Shanghai steel engine GQ-ZLG200 representatives Fruit Vegetable Preservation vacuum cooling machine, GQ-ZLS200 behalf of cooked vegetables fresh food-type vacuum cooling machine); 3, fresh vegetables vacuum cooling machine Siamese and split fresh vegetables vacuum cooling machine vacuum box by the host, Food condenser (optional), with the host by the vacuum pumping system, cooling system, control system, sheet metal (304 immortal quality steel) housing and other components. When the vacuum enclosure is greater than 2m3, its host and if the Siamese bulky vacuum enclosure, the general sub-structure; if the field installation conditions, but also do component body when the vacuum box ≤2m3, generally made piece, structure. Fresh vegetables, fresh vegetables, vacuum cooling machine vacuum cooling machine definitions (GQ-ZLS200) that is fresh vegetables vacuum cooling machine is the same product in different name. It mainly consists of a vacuum box, vacuum pumping systems, cooling systems, control systems, sheet metal (304 immortal quality steel) housing and other components. The central kitchen is rapid and uniform cooling precooled important, necessary equipment food companies fruit and vegetable preservation, cooked food, lunch, seafood and so on. Fresh vegetables, cooked food vacuum cooling machine to solve the temperature easy to breed harmful bacteria in the food production process with the problem, and cooked food in place of the longer time 30 ℃ -60 ℃, its fermentation and bacteria faster, which will lead to food spoilage and decay accelerated, shortening the shelf life of food products (shelf life). Vacuum cooling is cooked fast food industry is more advanced cooling technology, she can effectively address these problems.
