Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, use the volatilization of the refrigerant to immediately cool the air in the air, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore it is necessary to be careful to select extensional perlite as cold storage.Irving,Before the installation of the controlled atmosphere warehouse, we should also know how long the time demand for freezing goods is. After the installation of the controlled atmosphere warehouse, it can be divided into fresh-keeping warehouse, cold storage, frozen storage and quick-frozen storage. The first thing for the fresh-keeping warehouse is to store regular items, the first thing for the cold storage is to store items below zero, and the first thing for the frozen storage is items around zero, The freezing time code takes hours. If it is put into the quick freezing warehouse, it only takes to hours to reach the phenomenon of quick freezing. In the process of depositing goods, if the temperature is too low, it will affect the normal temperature of the deposited goods. The high price cold warehouses of various specifications are installed installed, and medical cold warehouses are supplied in time, High cost performance, has become the preferred brand for many wire products, welcome to buy! It will also affect the shelf life.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 indoor space between the pile and the wall, 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,IrvingCold storage installation Telephone, special tool warehouse, loading and unloading platform, etc.Mao,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.Cold storage board, compressor, and other components in the cold storage can reasonably adjust the evaporation and condensation temperature, so as to improve the reduction of power consumption and reduce the production cost. Professional cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, quality assurance, professional, timely supply and high cost performance. It has become the preferred brand for many wire products. Welcome to buy! Save more resources.No matter whether the food cold storage or quick-frozen storage is in use, it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.
The bacterial action of acid disinfectants is mainly to coagulate the protein in the bacteria. Common disinfectants include lactic acid, bleach, formalin, etc. Specifically, 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, which makes the vinegar absorb a lot of fish smell.Precautions for transforming the warehouse into a fruit preservation warehouse: determine the area and height of the cold storage according to the estimated number of fruits. In this way, after all, the warehouse is too large and the stored fruits are too few, resulting in a large waste of electric energy.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate,IrvingCold storage manufacturing and installation, compressor line is disconnected, fuse is blown, thermal relay acts, high voltage switch acts, compressor is locked, ambient temperature is too high, condenser is blockedCustomer first,Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example, the insulation and sound insulation effects of polyurethane insulation board are relatively good, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, the cold storage will consume more energy during operation, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next, let's understand the physical properties of polyurethane insulation board.In order to ensure the safety of construction and cold storage operation, sorting room and the polyurethane top storage plate (mm thick) has a span of m.Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, quick freezing room, refrigeration room, channel, unloading platform, etc.
The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.Respect for customers, which is mainly composed of compressor, condenser, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.The valve shall be installed as close as possible to the cooling fan. The solenoid valve shall be installed horizontally, the valve body shall be vertical, and pay attention to the liquid outlet direction.However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.Irving,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, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.Cold storage has good fire and flame resistance. After adding flame retardant, polyurethane is a kind of flame retardant and self extinguishing material. If it is burned by fire,IrvingInstallation of large cold storage, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be closed as a whole after fire prevention treatment to form non combustible products.No matter whether the food cold storage or quick-frozen storage is in use, it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.
