Refer:  The advantages of using a cold storage for agriculture . The 5 advantages of agricultural cold storage: Below are several advantages of agricultural refrigeration: Extend the life of fruits and vegetables and reduce the spoilage rate of perishable products Fresh food is perishable and is susceptible to pests and spoilage. In general, controlling temperature and relative humidity and preventing damage can greatly extend shelf life. Cold temperatures help reduce the rate of chemical change in perishable products, which can help delay the ripening of fruits and their aging. thereby extending the shelf life of fresh vegetables and fruits. Cost-effective This wastes a lot of money when perishable goods go bad due to improper storage. Cold storage extends the life of fresh produce by avoiding spoiled products, which will provide cost-effectiveness to businesses. Another way, cold storage can provide cost benefits is through energy bills. An efficient and high-quality cold storage...

Causes of cold storage ice freezing problems and how to prevent them Cold storage is very useful in companies that need to store food products. In addition to storing food, cold rooms help maintain the quality of products thanks to their cooling capacity. With cold storage, cold storage owners can benefit from scalable storage capacity, improved accessibility, and effective temperature control. However, a concern that may be noted with cold storage is the problem of ice forming. Freezing can seriously affect the cooling and storage functions of a cold storage facility, so that’s why it’s important to understand what causes them and how to prevent them. Causes of ice freezing problems There are many possible causes of freezing problems in cold storage. One of the known causes is the inflow of warm, moist air into the cold room. Usually, cold storage components have effective seals that keep warm air out. However, if these components begin to lack the ability to seal, then it is possible...

How to use the cold room to reduce vegetable loss? - CRYO SYSTEMS refrigeration Vegetable loss happens during fruit gathering, storing, transportation and sale every time. But how to avoid loss? 1. The first way is Pre-test precooling Now we need to know the main reasons for the loss of vegetables: Microbial infection:  In infected vegetables, micro-organisms are mainly fungi and bacteria, these micro-organisms are from some vegetables and farmland, such as potato late blight, carrot sclerotia, radish black rot, sick vegetables can Continue to spread hazards; some micro-organisms in the storage and transportation or even sales began to endanger the vegetable products, these microorganisms are mostly mold and corrupt bacteria, causing vegetables to grow mold, rot, smelly, causing losses. Vegetable physiological and biochemical reactions:  Vegetable harvest after a period of time, there are still breathing and other life activities, which respiration and a variety of physiologic...

For how to reduce the cost of cold room for food storage, what treatments and adjustments need to be made, let’s take a look at this full article: 5 tips to reduce the food storage cold room cost . 1. Use suitable building materials Several building improvements to consider include, Insulated Panels, Insulated Doors and seals, LED Lighting and so on. 2. Configure a reasonable heat exchange system 3. Clearly remove frost in the evaporator in time 4. Reasonably adjust the operating parameters of the refrigeration system to improve the efficiency of the equipment 5. Prevent impurities from entering the refrigeration system of the cold storage   Not only the construction and material cost of cold room should be considered, but also the correct use and maintenance of these cold storage buildings can reduce the heat load of the refrigeration unit and reduce the energy consumption of refrigeration, and reduce the cost of the cold room. If your want to build suitable cold room storage, and...

The standard operation of a screw compressor unit is an important step to ensure the unit works well and has a long service life. Below lists are the steps: 1. Refrigerant gas charged. The  screw compressor unit  needs to charge refrigerant on site. The refrigerant quantities and type must be in accordance with the regulations. Before charging, the quantities of refrigerant should be enough. In these cases, when the refrigerant charge is insufficient, it will lead to insufficient cooling capacity. When the refrigerant charge is too large, it will not only increase the cost but also have a negative impact on the operating energy consumption. 2. Operation of the screw compressor unit After the finished refrigerant is charged, we need to power on to operate and set the unit. During operation, bellows need to notice. (1) Check if all valve on the compressor unit is opened completely. Especially the discharged valve. (2) For water-cooled or water chiller unit, please open the conde...

The influence of the change of suction pressure on the refrigeration system When the refrigeration system is running, its suction pressure has a close relationship with the condensing temperature and the circulating amount of refrigerant. For systems that use capillary tubes for throttling, the suction pressure is related to condensing pressure, refrigerant quantity, compressor efficiency, and cooling load. Therefore, when checking the refrigeration system, a pressure gauge should be installed in the suction pipe section. Reading the suction pressure provides an important basis for analyzing faults. Factors of low suction pressure. The suction pressure is lower than the normal value due to the following factors: small amount of refrigerant, small cooling load, low condensing pressure and poor filter flow. The above factors will reduce the circulation flow of the system, and the heat load of the condenser will be correspondingly reduced, so that the condensation pressure will drop. And ...

The effect of changes in exhaust pressure (condensing pressure) on the system When the refrigeration system is running, the exhaust pressure corresponds to the condensation temperature, and the condensation temperature is related to the flow and temperature of its cooling medium, the amount of refrigerant injected, the efficiency of the compressor, and the amount of cooling load. When checking the refrigeration system, you can install an exhaust pressure gauge on the exhaust pipe when inspecting the refrigeration system to detect the exhaust pressure as a fault analysis data. Factors of high exhaust pressure. The exhaust pressure is higher than the normal value due to the following factors: low cooling medium flow rate or high cooling medium temperature, excessive refrigerant charge, heavy cooling load, etc. The above factors will increase the circulation of the system, and the condensing heat load will increase accordingly. In order to adjust the heat dissipation, the only way to incr...
