XPS Board Production Line

The 3D wire mesh panel machine is the main machine of the 3D panel production line, which adopts PLC control system, air cylinder or step motor as drive. It can insert, cut, and control the position of wire mesh and EPS board automatically to complete the production of the 3D panel. 3D wire mesh welding line for […]



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, […]


How to Working ? The principle of expansion valve and system debugging operation

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.


Introduce of Fresh Vegetables and Fruits Precooling Technologies-4-6

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.
