Cold Storage and Cold Chain

Cold storage is a method to preserve the frozen food under the cold storage temperature (often above the freezing point).
Especially for fruits and vegetables, it is mainly to delay their life metabolism and maintain their freshness.Generally, the refrigeration temperature is - 1 ℃ ~ 8 ℃.
The cold storage with this temperature is often called high-temperature cold storage. By reducing the rate of biochemical reactions and changes caused by microorganisms, refrigeration can prolong the shelf life of fresh food and processed products.

Cooling fan as a kind of cold storage evaporator. The cooling fan is the equipment that outputs the cooling capacity in the refrigeration system, mainly composed of cooling coil and axial fan. The axial fan of the cooling fan is responsible for the forced convection circulation of the cold storage fan and the air in the cold storage through the forced action to achieve the purpose of cold storage refrigeration. Cold storage fan is mostly a complete set of equipment consisting of axial flow fan and cooling ducts. Cooling fan according to the way used to cool the air can be divided into dry, wet and mixed dry and wet three. Among them, the refrigerant or refrigerant carrier in the flow of the exhaust pipe, through the wall of the tube to cool the air outside the tube is called dry chiller; to spray the refrigerant carrier liquid directly and the air for heat exchange, called wet chiller; hybrid chiller in addition to cooling the exhaust pipe, there is a refrigerant carrier spray device.

PBM motor and fan, as a professional cooling fan manufacturer and supplier, we provide high quality cooling fans and motors that can meet your cold storage and cold chain needs.

For most foods, cold storage can not prevent food from spoilage as can storage, dehydration or frozen storage, but can only slow down the deterioration speed of food. Therefore, it is actually a storage technology with relatively weak effect. However, not all foods can prolong the shelf life under cold storage conditions. For example, some tropical and subtropical fruits and some vegetables will suffer from chilling injury if stored at 3 ~ 10 ℃ above their freezing point, and the aging rate of bread will accelerate at low temperature.

Cold Chain refers to certain food raw materials, processed food or semi-finished products, special biological products and drugs. After being purchased, processed and inactivated, all links of cold chain are always in the specific low-temperature environment necessary for products in the process of product processing, storage, transportation, distribution, retail and use, so as to reduce loss and prevent pollution and deterioration, so as to ensure food safety, biological safety Special supply chain system for drug safety.

Freezer, cold storage and cold chain for foods, vegetables , fruits fresh-keeping are stepping from commercial to civil. Coronavirus gave impetus to the tendency speeding up from spring of 2020 when COVID-19 pandemic broke out in worldwide. This tendency gives PBM motor and fans an very good opportunity to satisfy civil residents requirements of lower power consumption and more quiet to make their to keep economic living cost and to be healthy.

By comparing the actual operation and maintenance costs in entire fan life cycle,
it is concluded that our fan can ideally meet the market requirements as appropriate solutions.
