Tulzia cimpia turzii.The controlled atmosphere warehouse is mainly used for the storage and processing of fruits. It can keep the low temperature of fruits in the cold warehouse and make the storage time longer. The walls of the cold warehouse are equipped with heat insulation panels, and the bottom is equipped with quick boards to prevent moisture and heat from the outside, Today we'll take you to know some precautions about how to store fruits in the cold storage: disinfection treatment before fruits are put into the fruit preservation cold storage: the cold storage should be disinfected before fruits are put into the fruit preservation cold storage. Sulfur is used for disinfection. Generally, and then use sawdust to ignite and close the doors and windows. Don't open the doors and windows within two days. The storage volume of fruits should not be too large every time. It's good if the daily purchase volume is about 10%.
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 kg of sulfur can be used for disinfection of 100 cubic meters, how to seal the refrigeration equipment is the key. First of all, all through wall pipelines must be equipped with sleeves, 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, 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.
.Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.

Welcome to consult. Pay attention to its compactness and continuous uniformity.
The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating, good waterproof performance, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation protection and long service life. The corner shall be temporarily fixed with 0.5 color plate angle steel; When installing each wall panel, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place, and the rivet spacing in the warehouse should be 300mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.
The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.
If the refrigerator has been used for more than months, or the high / low voltage switch often fails, or the refrigeration capacity is reduced, please arrange staff to clean the condenser. If the ultra-thin light box is repaired according to the above instructions for many times, and the refrigerator fault still sounds for a long time, please ask the maintenance personnel of the refrigerator to repair it.
Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.
Interpretation and observation.The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.
The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.
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 50 degrees Celsius. Then, 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.
The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, it needs to be checked in time.
project.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof moisture-proof, anti-collision, anti binding and other safety protection.
Another point is the ground maintenance measures in the wholesale of large fresh-keeping warehouses., Because the wholesale floor of large-scale prefabricated fresh-keeping warehouse is also a thermal insulation board, there will be a lot of ice on the ground in the process of use, so when cleaning these ice layers, you should pay attention not to beat them with a hammer or shovel, because it will damage the thermal insulation board on the ground. If the thermal insulation board is damaged, it will affect the thermal insulation performance of the wholesale of fresh-keeping warehouse.
1 - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place, and do a good job in the floor and evaporator drainage system.

The refrigerator compressor unit generally adopts high-end units with guaranteed quality and strong operation stability. The evaporator adopts the imported joint venture refrigeration air-cooled evaporator, which can effectively meet the refrigeration capacity of the refrigerator and ensure the refrigeration effect of the refrigerator. The refrigerator lamp adopts the special LED energy-saving lamp for the refrigerator, which has the advantages of low temperature resistance, low energy consumption and long service time, It can effectively save the operation cost of cold storage.
The service life of the cold storage depends on the quality of the refrigeration equipment, but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times, people often ignore the latter point. In daily life, as long as we maintain and maintain the cold storage regularly, we can greatly improve the service life of the cold storage and reduce the cost.
