Cold Chain Logistics And Refrigerated Transportation Are Experiencing A Period Of Unprecedented Growth. New technologies have made it possible to get fresh, perishable foods from one side of the world to the other without putting the integrity of the foods at risk. Similarly, state-of-the-art temperature controlled containers and trailers make it possible to get valuable, […]
Thermal expansion valve is mainly composed of sensing mechanism, executing mechanism, adjusting mechanism and valve body. When the temperature of the bulb decreases, P1 P2+F, the valve opening decreases and the refrigerant flow decreases proportionally. When the temperature of the bulb rises, P1 > P2+F, the valve opening increases and the refrigerant flow increases proportionally.Thermal expansion valve is an important automatic control component of refrigeration system, which is divided into external balance type and internal balance type according to different balance modes. It is generally installed between the liquid storage tank and the evaporator. It uses the temperature change of the temperature sensing bulb as a signal to adjust the opening of the valve and change the refrigerant flow, so that the medium-temperature and high-pressure refrigerant can be throttled into low-temperature and low-pressure wet steam, and then the refrigerant absorbs heat in the evaporator to achieve refrigeration effect.
When designing a business, company, or business in the food industry, you should immediately think about the construction cost of cold storage . Here we give you the answer you need: cold storage. Know everything that implies having it, why, and how to use it.What is cold storage?
Ice pre-cooling is to absorb the heat of fruits and vegetables through the melting of ice to cool the fruits and vegetables. It includes putting ice in the packing box or tray, or covering the tray with ice. This cooling method is actually often used in transportation. The ice cooling method is suitable for products that are not easily damaged by contact with ice or products that require immediate pre-cooling in the field.
