When purchasing, we should make reasonable comparison and select products suitable for our own use needs and economic conditions.The type of cold storage to be built in the cold storage type shall be determined according to the type of circulating goods. For example, a cold storage that only circulates vegetables can only establish a fresh-keeping cold storage. If there are many kinds of circulating commodities and large differences in storage temperatures, a cold storage of refrigeration + freezing will be established. As for the size of the cold storage, it shall be determined according to the type, quantity, frequency, cycle, whether to use shelves for stacking, etc. For example, for fruits and vegetables packed in cartons, andHow to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.market price,Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.The polyurethane insulation board used in the construction of cold storage shall be integral and continuous, and there shall be no joint in the middle. The junction of polyurethane insulation board, top plate and ground shall be made into fillet arc for transition, which can well meet the health needs.Judge the operating sound of the compressor,BrosadCold storage price of fresh vegetables,BrosadHow much does it cost to install a cold storage, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.

On the basis of cold storage and preservation, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables. Generally, controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK what is the standard of quick freezing warehouse?Honesty and mutual benefit, - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place, and do a good job in the floor and evaporator drainage system.The controlled atmosphere warehouse is mainly used for the storage and processing of fruits. It can keep the low temperature of fruits in the cold warehouse and make the storage time longer. The walls of the cold warehouse are equipped with heat insulation panels, and the bottom is equipped with quick boards to prevent moisture and heat from the outside, Today, we'll take you to know some precautions about how to store fruits in the cold storage: disinfection treatment before fruits are put into the fruit preservation cold storage: the cold storage should be disinfected before fruits are put into the fruit preservation cold storage. Sulfur is used for disinfection. Generally, kg of sulfur can be used for disinfection of cubic meters, and then use sawdust to ignite and close the doors and windows. Don't open the doors and windows within two days. The storage volume of fruits should not be too large every time. It's good if the daily purchase volume is about %.In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first.
