EsparzaDesign and installation of fruit and vegetable cold storageWhat to know about

every 1 ℃ increase in the evaporation temperature of the cold storage can save energy by 2 ~ 5. Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.

It is built in the room. There shall be excellent drainage pipe standards around the cold storage, the soil temperature shall be low, there shall be interlayer under the cold storage, and good natural ventilation shall be maintained. Maintaining dryness is very important for the cold storage. In addition, before the construction of the cold storage, the tap water pipeline shall be paved and the FRP cooling tower shall be built.

Esparza.The air in the controlled atmosphere storage shall have appropriate circulating stream to make the air temperature in the storage uniform. If the circulation stream is not carried out, the air in the warehouse absorbs the respiratory heat of vegetables and the heat leakage of various parts which increases the upper temperature and is easy to deteriorate the products. Especially soon after vegetables are put into storage,EsparzaFresh keeping cabinet for fruit, it is more necessary to strengthen ventilation and circulation.

Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid, without hollow feeling, load-bearing, antifreeze, moisture-proof,EsparzaInstallation and construction of cold storage, etc.

.The spacing of pull rivets at inner and outer corners is 300mm and 200mm respectively; After the polystyrene library is installed the wall panel joints shall be evenly sealed and decorated with silicone sealant.

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, it can be carbonized, unlike flow burning and flashover like extruded board, it can be closed as a whole after fire prevention treatment to form non combustible products.

These measures have achieved quite good results. Compared with several cold storages at a customer in Jining, the cold storages using their white materials have significantly lower power consumption than those using other white materials.

However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.

For the installation of refrigeration unit, oil separator shall be installed for semi sealed or fully sealed compressor, and an appropriate amount of oil shall be added in the oil. When the evaporation temperature is lower than - 15 ℃, gas-liquid separator and an appropriate amount of refrigeration oil shall be added.

Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.

Convenient and efficient.The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.

At ordinary times, users should check the sealing degree of the gap of the cold storage, and notify the cold storage for maintenance in time if damaged parts are found.

When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.

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, installation of cold storage, 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.

reform.Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Fault phenomenon of cold storage: the dryer does not operate, the compressor line is disconnected, the fuse is blown, the thermal relay acts the high-voltage switch acts, the line is falsely connected or loose. Fault phenomenon: it stops in a short time after the drying motor, and the environment

Precautions for fruit delivery: it is the same as warehousing. It should be gradually adapted during delivery to avoid condensation on the fruit surface, dark color, affecting the taste and causing decay. The temperature should be 2 ~ 4 ℃ higher than the fruit temperature each time, and the relative humidity should be 75% ~ 80%, it can be delivered from the warehouse.

Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.

Esparza.These measures have achieved quite good results. Compared with several cold storages at a customer in Jining, the cold storages using their white materials have significantly lower power consumption than those using other white materials.

When the cold storage is used for the first time or shut down for a long time, 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.

Relative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important from centrifugal humidification to high-pressure micro fog humidification, gas-water mixed humidification, to the current ultrasonic humidifier. The utility model has the advantages of small particles, uniform humidification, no freezing and blocking, and no dirty blocking. The air conditioning humidifier we produce is specially designed for all kinds of vegetable and fruit quick freezing warehouses, which is essentially different from other humidifiers in the market: fully closed circulation, that is, take the gas in the warehouse, return to the warehouse through the humidifier and isolate it from the outside air.
