Price.The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following 6 points: a low-temperature hall, a closed platform, an electric sliding refrigerated door, an anti-collision flexible seal, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.
During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.
Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage, plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, such as working intermediate, packaging and combing room,RichmondHow much is the installation of small cold storage, special tool warehouse, loading and unloading platform,RichmondQuotation for installation of fresh-keeping cold storage, etc.
Compression refrigerator is commonly used, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.
Quality assurance.The quantity is large, and a special tally room (area) is set according to the needs of production and operation. The temperature of the tally area is usually controlled at 0 ~ + 7 ℃.
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, 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 100 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 10%.
Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.
Richmond.There are many kinds of cold storage. According to the material, it can be divided into color steel plate, stainless steel plate and salted steel. Among them color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is 0.5mm and 0mm, without color requirements; The thickness of salted steel plate is 0.5mm without color requirements; The thickness of PE paint baking board is 0.5mm, 0.8mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the 150 mm storage plate is 150 mm, and the thickness of the vertical plate is 160 mm and 100 mm, which is suitable for the insulation conditions of - 25 ℃ ~ - 45 ℃; 100mm storage plate: the thickness of the ceiling plate is 100mm and the thickness of the vertical plate is 110mm, which is suitable for the thermal insulation conditions of 0 ℃ ~ - 25 ℃. The thickness of the ceiling plate and the vertical plate of 60mm storage plate is 60mm, which is suitable for the thermal insulation conditions above 0 ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = 900mm, heaven and earth plate width WB = 980mm, vertical angle plate W1 = 790mm, W2 = 840mm, W3 = 740mm and W4 = 880. The dimensions of non-standard plates are different from those of Wa, WB and W4.
1 - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).
Requirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore, how to seal the refrigeration equipment is the key. First of all, all through wall pipelines must be equipped with sleeves, due to the good sealing of the quick freezing warehouse the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.
