New-OrleansHow much is it to install a 30 square meter cold storageWhich four levels of technology are the four major standards?

With the increasing use of cold storage, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore, some small problems may be ignored during installation. According to the following understanding.

When outdoor air enters the cold storage body,New-OrleansFruit cold storage temperature, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, being damaged by moisture and freezing. Therefore, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.

New-Orleans.The cold storage construction in the site selection undertakes the circulation of low-temperature goods. Therefore, priority should be given to the transportation convenience of the cold storage construction site, such as close to roads and railways. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.

During operation, the water temperature will still drop, and the humidification amount will be reduced by 70% at 5 ℃.

.The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.

Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.

Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.

Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it which is easy to cause horizontal freezing and swelling.

Fresh keeping storehouse is a building with artificial refrigeration to make the fixed space reach the specified temperature and facilitate the storage of goods. Fresh keeping warehouse wholesale can be widely used in food factories, dairy factories, and so on. The following are the functions of the main parts of the fresh-keeping warehouse wholesale.

The construction of small cold storage is widely used in life, such as food industry, manufacturing industry,New-OrleansMake fresh-keeping cold storage for vegetables and fruits, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.

Where is good.Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall, such as the sudden shower after a long time of exposure, or shading during exposure, will not cause damage to the surface of the cold storage.

Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.

During the cold storage commissioning, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.

Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it which is easy to cause horizontal freezing and swelling.

Good reputation.The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.

After the fresh-keeping storehouse is built, it is also important to pay special attention to the maintenance of fresh-keeping storehouse equipment in the whole process of application. Here are some key maintenance matters.

Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be 10 ~ 12 seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; 1TR time relay is broken (relay unit).

New-Orleans.The two sets of connectors between the cold storage shall be wedged tightly and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.

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,New-OrleansInstallation of cold storage works, 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, 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.

The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection, such as proximity to roads, railways, etc. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.
