Cold storage preservation is to inhibit the activity of microorganisms and enzymes cold storage, storage methods to extend a period of fruits and vegetables forever. Fresh fruits and vegetables, a temperature range of 0 ℃ ~ 5 ℃, keeping storage can reduce the incidence and rate of fruit rot pathogens, and can also slow down the metabolic processes of fruit respiration meat cold storage, which prevents the decay and prolong storage life purpose . Dongguan City-long Refrigeration Electrical Equipment Engineering Co., Ltd. is located in the manufacturing city of Dongguan City, Guangdong Province, with convenient transportation wanjiang cold storage, specialized in the central air-conditioning, chillers, cooling equipment, the combination of cold storage, to build cold storage, freezing, temperature and humidity engineering, and central air conditioning, cold pipes, all kinds of ventilation decontamination, such as sales, design, installation and maintenance of train services. Quick-frozen food cold storage refers to the rapid adoption of the biggest ice generation area, when the average temperature reaches -18 ℃ sometimes rapid freezing method. A wide variety of food will change in the freezing process, such as physical changes (volume, thermal conductivity, specific heat, dry consumption changes, etc.), chemical changes (protein denaturation, discoloration, etc.), changes in tissue and biological and microbiological of change. Is characterized by the rapid freezing of food to maximize their food original color, flavor and nutritional value. That is, in the freezing process must ensure that these various changes that occur in food maximize reversibility.
