Initial stage of cold storage equipmentHowever, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.Gottingen,Daily maintenance and management of fruits after Warehousing: timely the temperature and humidity in the cold storage, strictly control the temperature in the cold storage, timely eliminate the bad gas in the cold storage, and adjust the temperature and humidity of the cold storage according to the different requirements of different fruits on the storage environment. If long-term drying will affect the color of the fruit, consider using a humidifier to adjust the humidity in the cold storage.Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.Djibouti,It is required to set up a special tally room (area), and the temperature of the tally area is usually controlled at ~ + ℃.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,GottingenFruit cold storage, the frost flushing water return pipeline must be equipped with U-shaped bend water seal, and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition,GottingenRefrigerated drugs, 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.Installation of cold storage, construction of cold storage, fruit preservation cold storage and medical cold storage have stable, safe, reliable and maintenance free performance. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.
The average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.Does the cable wire meet the parameters? In general the cold storage needs to use phase electricity.Cold storage is mainly used for frozen processing and storage of foodGood reputation,Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials, the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, the attic on the top floor can be built into the ice making room, etc.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption, good permeability to water vapor, foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface, 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.Focus on Development,The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.The air in the controlled atmosphere storage shall have appropriate circulating stream to make the air temperature in the storage uniform. If the circulation stream is not carried out the air in the warehouse absorbs the respiratory heat of vegetables and the heat leakage of various parts, which increases the upper temperature and is easy to deteriorate the products. Especially soon after vegetables are put into storage, it is more necessary to strengthen ventilation and circulation.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.Gottingen,Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes,GottingenCold storage frozen products, and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following points: a low-temperature hall, a closed platform, 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.
