On the basis of cold storage and preservation the quick-frozen warehouse increases the regulation of gas composition, inhibits the respiration of fruits and vegetables, delays their metabolic process, better maintains the freshness and commercial quality of fruits and vegetables, and prolongs the storage period and shelf life of fruits and vegetables. Generally, controlled atmosphere storage of fruits can prolong the storage period by & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance, but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification, with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate, cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. Polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.Matagalpa,Maintenance space shall be reserved for the installation of the unit to facilitate the observation of the adjustment of instruments and valves.The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?Inisa,The construction of small cold storage is widely used in life, such as food industry, manufacturing industry, 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.For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.Strong deformation resistance, not easy to crack, smooth, stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption performance. Under normal service and maintenance conditions, the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period, it can reach the unit price of dry, wet or electric corrosion under normal service conditions, while the unit price of insect, fungus or algae foam material is higher than other traditional insulation materials, but heating will increase the cost and the cooling cost will be greatly reduced.

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, 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.Pressure leak test: the system pressure leak test is the same as the blowdown work sample, which is required to be carried out by air compressor.The physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.Product line,Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.

Generally speaking,MatagalpaPrice and installation of cold storage project,MatagalpaHow much is the installation price of cold storage? One square meter, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.Affordable price,First, so as to make the boards closely close to each other. Two sets of connecting pieces shall be wedged between the wall panel and the wall panel, and the two sets of connecting pieces shall be fixed on the upper, outer and lower sides of the gap between the wall panel and the wall panel respectively. The lower connecting piece shall be as close as possible to the lower side,MatagalpaFast cold storage, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate, trim the plate edge, and then reinstall it to make the plate joint meet the requirements. When fixing the adapter, pay attention to fix the two parts of the adapter on the edges of the convex and concave library plates respectively, and fix them with rivets. The spacing of the adapter should be able to tension the two library plates. When wedging the wedge iron, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time, and the wedge iron shall be fixed with rivets.The set values of various protective devices of the unit have been adjusted by the factory. Users are not allowed to change them at will.The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.Matagalpa,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.Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.With the rapid development of modern commerce the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?
