San IsidroFresh frozen foodWill the quality get heavier
The drainage at the outlet of the cooling fan, the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software, but indirect drainage shall be adopted. For the flushing (thawing) water drainage of each layer in the double-layer cold storage, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.San Isidro,An air duct is generally set in the vegetable cold storage. The air flow from the upper air duct mouth blows to the wall and the lower product line, returns to the middle, is absorbed by the lower part of the evaporator, and the evaporator drains and returns to the air duct again.The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.Sabana-Grande-de-Boya,Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.During the installation of polystyrene storehouse, the mm gap shall be marked with foaming material to ensure the sealing performance of the warehouse body.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.
General quick-frozen warehouses are mostly cooled by refrigeration mechanisms and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.The air washing and ventilation of the cold storage is in the long-term sealed LIUCai storage, it will have an adverse effect on the storage of vegetables. Therefore, ventilation device or air washing device is designed in the general warehouse.Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.Free consultation,Polyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.The importance of regular oil discharge, but use fan to supply air for refrigeration descaling and air discharge in the refrigeration system of the warehouse.The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.
The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling,San IsidroInstallation price of large cold storage, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse,Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.The cold storage construction in the site selection undertakes the circulation of low-temperature goods. Therefore when selecting the site, 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.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, without color requirements; The thickness of salted steel plate is .mm, without color requirements; The thickness of PE paint baking board is .mm, .mm 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 mm storage plate is mm, and the thickness of the vertical plate is mm and mm,San IsidroCold storage board installation design, which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm, which is suitable for the thermal insulation conditions above ℃. 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, heaven and earth plate width WB = mm, vertical angle plate W = mm, W = mm, W = mm and W = . The dimensions of non-standard plates are different from those of Wa, WB and W.San Isidro,General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon) - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place, and do a good job in the floor and evaporator drainage system.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.
