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.
2. Cold water pre-cooling Cold water pre-cooling is a cooling method that uses water as a medium. The fruits and vegetables are immersed in cold water or rinsed with cold water to achieve the purpose of cooling. There are two types of cooling water: low temperature water (usually around 0～3℃) and tap water. The former […]
Fruits and vegetables still have a lot of field heat after being picked. This heat guides the critical growth and rapid aging of plants. This heat is also coordinated with the release of trace elements in the moisture exposed by the mechanical damage left by the picking or processing of vegetables and fruits. Accelerate the discoloration of fruits and vegetables, and coordinate with the moisture on the surface of fruits and vegetables to nourish a large number of fungi and quickly corrupt the body of fruits and vegetables.
Cold air pre-cooling is actually what we usually call cold storage, which makes cold air flow quickly around the product to cool it. Air cooling can be carried out in a low-temperature storage warehouse.
The following is a complete overview of the voltage and frequency of all countries in the world and their respective plugs, sockets and household appliances. The table shows that in most countries, the mains voltage is between 220 and 240 volts (50 or 60 Hz); the number of countries operating at 100-127 volts is particularly small. In addition, Type A and Type C are the most commonly used electrical plugs in the world.
Many logistics companies are familiar with the problems of draughts at industrial doors of warehouses.Air curtain factory.
The food cold storage mainly stores meat products, tea leaves, edible fungi, milk products, agricultural products, fruits, vegetables, aquatic products, cold drinks, ice cream, etc. The insulation boards of the food cold storage uses color steel, glass steel, stainless steel and other panels.
For medicines with quality not preservable under room temperature conditions, refrigerating them at low temperature will retain their quality, keep them effective and extend their shelf life. The sheet material of the medicine cold storage uses modern high-tech flame-retardant insulation materials which has excellent airtightness. Casgy’s medicine cold storage follows design norms and is energy-saving and environmentally friendly.
As less energy is needed to cool the grain to safe storage conditions compared to drying it, substantial quantities of energy can be saved, reducing the impact on global warming. Safe guarding storage conditions also reduces grain loss, which is a major benefit for the environment. The ZKGYLL Grain Cooling Unit also uses 80 percent […]
Water cooled chillers are mainly used in cold storage. It can be used in combination with various types of compressors such as scrolls and screws according to user needs. The product can provide various temperatures and cooling capacity required for fresh-keeping, refrigeration and freezing,
The condenser coil is similar to a evaporator coil. The difference between condenser and evaporator coil is reversed. When the refrigerant realese its heat, a fan blows the air through the condenser coil and heat is pass into the outdoor air.
