According to the size and nature of the cold storage area and in combination with local regulations, the construction form of food cold storage warehouse is to determine the plane layout based on the site whether it is a single-layer or double-layer warehouse, and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity, production process, refrigeration product stacking, temperature, etc. are used to determine the size and location of the cold storage room, so that it can become a whole.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,ChakaritaHow much is the installation of small cold storage,The customer specifies the refrigeration and conversion conditions required by the customer, the temperature of refrigeration and refrigerant, and the provisions of the customer's application site and application installation level.Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.Valparaiso, electric door, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.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 installation of cold storage board in cold storage, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored, and avoid the wrong installation, refrigeration devices are becoming more and more common. All aspects of life are inseparable from its use. Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage so as to waste resources and increase the cost.
With the development of the times, it is important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need to grasp its key points in the production process of cold storage.The machine room shall be equipped with oxygen respirator, gas mask, gas clothing, rubber gloves, wooden stopper, pipe clamp, acid beverage and other necessary protective and rescue articles, which shall be set in a convenient location, managed by a specially assigned person and used regularly. Relevant personnel shall skillfully master the use of oxygen respirator and personnel rescue.The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, with freon as the refrigerant. The evaporation mode in the warehouse is the cooling fan, which can be ceiling type. If the number of warehouses is small and the volume does not exceed cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses, the mode of multiple heads in parallel can be considered.Professional is king,Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting, ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage,ChakaritaWhere is a large cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.It will still decrease. The humidification amount will decrease by % at degrees.Artificial refrigeration keeps the room at a constant temperature. The walls,ChakaritaCold storage by package, floors and flat roofs of large cold storages are laid with thermal insulation materials with a certain thickness to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color.
Fire retardant, flame retardant and high temperature resistant polyurethane is a kind of flame retardant self extinguishing material after adding flame retardant. Its softening point can reach more than ℃, and it will decompose only at higher temperature. In addition, polyurethane forms carbon deposits on the surface of the foam, which helps to isolate the foam below. It can effectively prevent flame spread.Direct material,In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.According to the technical requirements for the installation of cooling fan, when selecting the lifting point position, the position with good air circulation shall be considered first. Secondly, the direction of library structure is considered.General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)Chakarita,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.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, 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.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.
