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 2 & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?
Guihu.Air tightness test: air tightness test of fresh storage system, also known as leak detection process, which can be divided into pressure, vacuum and ammonia filling leak detection stages.
Before the acceptance and delivery of the project, it shall be treated. There shall be no obvious scratch on the board surface.
.The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable, but the project cost is relatively high.
Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.
Goods in and out frequently, throughput
It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is 15-20 degrees. If our humidifier is connected with the warehouse, there is no temperature compensation, even if
All equipment connections shall be laid with wire pipes and fixed with clips. PVC wire pipes shall be bonded with glue, and the pipe orifice shall be sealed and wrapped with adhesive tape.
The selection of cold storage is very important for cold storage, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low, and the air temperature, humidity and environmental requirements are relatively high. When selecting cold storage, the temperature in the cold storage is difficult to, which is easy to cause the deterioration of products in the cold storage, or the refrigeration compressor in the cold storage often works, wasting more resources and increasing the cost.
Direct labor.The quantity is large, and a special tally room (area) is set according to the needs of production and operation. The temperature of the tally area is usually controlled at 0 ~ + 7 ℃.
During the cold storage commissioning,GuihuAssembled cold storage, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.
Initial operation unit of cold storage equipment: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.
On the basis of cold storage and preservation, 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 2 & mdash; Three times or more. OK, what is the standard of quick freezing warehouse?
Product range.The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.
The warehouse shall be equipped with emergency lighting door lock opening and alarm devices, which can save themselves or call the police for help.
Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.
Guihu.For the ground insulation of large 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 15cm 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, the XPS extruded plate with thickness of 150 ~ 200mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of 100 ~ 150mm can be laid in the high-temperature cold storage.
For water-cooled units, the turbidity of cooling water shall be frequently,GuihuVegetable preservation and freezing warehouse, the cooling water shall be replaced frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.
The polyurethane insulation board used in the construction of cold storage shall be integral and continuous, and there shall be no joint in the middle. The junction of polyurethane insulation board, top plate and ground shall be made into fillet arc for transition, which can well meet the health needs.
