There should be excellent drainage pipe standard around the warehouse, the soil temperature should be low, there should be interlayer under the cold storage, and maintain good natural ventilation. Maintaining dryness is very important for the cold storage. In addition, before the construction of the cold storage, the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the tap water pipeline shall be paved and the FRP cooling tower shall be built.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, 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, so that the interlayer skin of the sprayed coating is thinner, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.Rocklen,Do not cut off the main power supply to shut down the unit unless it is an emergency; If the unit is out of service for a long time in winter, turn off the unit first, then turn off the main power supply and oil heater, and drain the water in the system.When using the cold storage, try to keep the ground clean and professional cold storage installation,RocklenMedical cold storage temperature,muar ,Floor insulation of small cold storage the structure of small cold storage is usually called surface that is, the top wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, after the fish comes out of the freezer, clean the frost layer on the evaporating pipe group and keep the storehouse temperature below degrees Celsius. Then, according to the volume of ~ grams per cubic meter volume of the frozen storeroom, the storeroom door is closed tightly with the sprayer and the blower is started intermittently, so that the vinegar evaporates and flows in the storehouse, reasonable design schemes store more goods than unreasonable ones. For the fixed size quick freezing warehouse, how to design it to maximize its space rate is often an important problem considered by our designers. In the design scheme of Lukang medical quick-frozen warehouse, we reasonably designed to expand the original storage capacity of boxes to boxes, which increases the space a lot.
It will still decrease. The humidification amount will decrease by % at degrees.Evaporator is not only an exchanger for refrigeration and bulk cooling, but also a very important one. Its task is bulk cooling. It is mainly used for refrigeration and heat absorption in fresh-keeping warehouse. In the long-term work of the fresh-keeping warehouse, the fins of the evaporator will also be covered with dirt, mostly pasted with some sundries of the products. It is specialized in products and renewable resources. Its business includes: cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage. In addition, dust and other things but reaching a certain thickness will have an impact on the cooling of the fresh-keeping warehouse, If the refrigeration of the fresh-keeping warehouse becomes poor, it should be cleaned with a special cleaning agent for the evaporator.Moreover,On the basis of cold storage and preservation, the quick-frozen warehouse increases the regulation of gas composition, 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?The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, we must combine the performance of the product and store it according to the temperature and humidity required by the product. The automatic temperature box also needs to be used outside the product cold storage. At the same time, the management personnel must be familiar with the operation steps of the medical cold storage project.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 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, special tool warehouse, loading and unloading platform, etc.
Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size,The cooking materials and foods refrigerated in the quick-frozen warehouse contain a certain amount of fat,RocklenInstallation diagram of cold storage sliding door, protein and starch. The existence of these nutrients will make molds and bacteria multiply and grow in large numbers. In order to do a good job in the hygienic management of cold areas and ensure the refrigeration quality of food and cooking raw materials, it is necessary to carry out the hygienic disinfection of cold areas regularly.Evaporator is not only an exchanger for refrigeration and bulk cooling, but also a very important one. Its task is bulk cooling. It is mainly used for refrigeration and heat absorption in fresh-keeping warehouse. In the long-term work of the fresh-keeping warehouse,RocklenHow much is the charge for cold storage installation, the fins of the evaporator will also be covered with dirt, mostly pasted with some sundries of the products. It is specialized in products and renewable resources. Its business includes: cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage. In addition, dust and other things, but reaching a certain thickness will have an impact on the cooling of the fresh-keeping warehouse, If the refrigeration of the fresh-keeping warehouse becomes poor, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.Rocklen,Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.The cooking materials and foods refrigerated in the quick-frozen warehouse contain a certain amount of fat, protein and starch. The existence of these nutrients will make molds and bacteria multiply and grow in large numbers. In order to do a good job in the hygienic management of cold areas and ensure the refrigeration quality of food and cooking raw materials it is necessary to carry out the hygienic disinfection of cold areas regularly.The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, especially in the process of periodic freezing and thawing cycle, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.
