Pre-cooling in the long-distance cold room transport of food or frozen in advance for a cooling method, the request is to be fast to the required food storage temperature. It is protecting the transportation of food quality and extend the storage life of the important measures. Pre-cooling and pre-cooling is usually conducted in the refrigerator. Pre-cooling methods commonly used natural air cooling, ventilation, cooling, vacuum cooling and cold water cooling. After pre-cooling treatment, the food should be promptly placed in cold room environments.

Refrigeration should pay attention to cold room some problems. Precooling.Can be refrigerated cold room where food, medicine and other equipment stored at low temperature in order to avoid deterioration. Cooling Optional: water-cooled or air-cooled. Compressor Optional: Open-type or semi-closed compressor Quantity: One or more. Implementation of a very energy regulation: can a machine library or stand-alone single library. Protection ability: high and low voltage protection with fluoride, hydraulic differential protection, phase, overload protection. High degree of automation: the implementation of library can automatically adjust temperature, cooling water, adjust, man-machine dialogue can be implemented using the PLC functionality. Refrigerator frozen food. Frozen foods, or frozen food, frozen food, frozen food, frozen after refers to processing of food. Frozen food is a very common method of food preservation, in addition cold room to significantly reduce food spoilage and chemical reaction rate, the better because the water freezes food, but also a serious impediment to microbial breeding, which can significantly extend the foods best before date. Many countries will have a large refrigerator, strategically save cold room a lot of food for national emergency purposes. Some agencies will seed stored in minus 18 degrees Celsius in the seed bank to plant species extinction in response to the situation. Saved seed crops, or more often rare species. Changes in the temperature range and allows storage period. Cold room temperature is not possible at a constant temperature, the result of cooler performance, storage capacity factors such as size and temperature difference between inside and outside the library temperature will fluctuate within a certain range. In general, the food is low storage temperature, and the range as small as possible. It is a good food preservation, to prevent loss and low temperature physical disease. Temperature control. Different foods have different optimum cold room temperature. After cold room temperature and storage temperature of food is affected by many factors, such as storage temperature and the library when the food temperature difference, refrigerator performance and storage capacity, database of air circulation, stack method, food variety and maturity and so on. Stacking storage should be reasonable, based on the actual temperature regulating reservoir conditions; the library before the need with gradually heating method, to avoid large temperature difference between inside and outside, resulting in condensation drops of food surfaces. Humidity control. Often due to a large number of cold room evaporator absorbs heat and constantly attached to frost in its last statement, but also keep the frost melts and flows away, causing bank humidity were lower than the food storage demands on the humidity. Increased evaporator area can be used to reduce frost, wet the installation of spray equipment or automatic device to regulate the humidity inside the refrigerator. In addition, when frequent access for goods, so that bank relative humidity increases, the device can be installed moisture absorption, and strengthening cold room management, strict control of access to goods and personnel frequently. Axial fan is the same direction with the flow (ie wind direction and axis parallel), such as electric fans, air conditioner fan is run axial fan. Known local fan axial fan is a fan common industrial and mining enterprises, security is different from the normal fan motor and fan it in a cylinder, the shape is a cylinder, for local ventilation, installation convenient ventilation effect is obvious, safe, hairdryer can take lookout sent to the designated area. According to the characteristics of axial fan to make the following categories:By material categories: steel fan, FRP fan, plastic fan, PP fan, PVC fans, aluminum fans, stainless steel fan and so on.End-use categories: proof fans, corrosion fan, explosion-proof fans and other types of corrosion.By using the required categories: pipeline, wall, post, fixed, rain and dust type, electric and other external. Axial Fan Application: used in metallurgy, chemical industry, light industry, food, medicine and civil buildings and other places for ventilation or to enhance heat dissipation purposes. If we remove the chassis can also be used as free fan, but also in the more long interval between the exhaust pipe installed in series to increase pipeline pressure. Axial fan features: simple structure, stable and reliable, low noise, wide range of functional options and so on.Axial fan work, power machine drive impeller rotating within the cylindrical casing, the gas flow from the collection devices to enter, access to energy through the impeller to improve the pressure and speed, and then along the axial discharge.Haile Electric Industrial Co. Ltd, as a member of the Sino-Resource Group, is the leading manufacturer and exporter of cold room,axial fan,condensing unit,centrifugal fan,shaded pold motor and refrigeration products in China.Axial Fan arrangement in the form of vertical, horizontal and tilt of three, small, about 100 mm diameter impeller, large up to 20 meters.
