Grain cooler machine equipment
About Grain Cooler
KINGFIT grain cooler is mobile refrigeration equipment, designed as characteristic of domestic food warehouse and climate, could be widely used in low-temp storage of food and other crops.
Qingfeng Low-temperature Grain Cooler function:
1. Reduce the loss caused by the pest and microorganisms grow. Don't need medicine fumigation, so as to reduce pollution, keeping food hygiene.
2. Slow down the metabolism of grain particle, delay quality aging and deterioration, keep the color, fragrance, flavor of finished product of grain, and maintain food eating quality. Especially suitable for the storage of rice, corn and fuel.
3. Reduce the wastage cause by grain breathing, insect, high temperature heating, mildew and turnover; The most greatly reduce the cost of storage.
4. Relax appropriately the storage be grain moisture, shorten drying process before being put in storage, not only save energy, but also can solve the problem of baking a large number of grain before store.
5. Low temperature storage cooling system can adjust grain temperature, reduce temperature difference to ensure the safety of storage, Take cooling processing of cold negative pressure mean temperature to guarantee the high water storage.
6. Prevent or eliminate moisture transfer, separation, condensation and exclude peculiar smell in pile to ensure safety and good quality storage
Qingfeng Low-temperature Grain cooler function Features:
1. Reliable operation: The introduction of advanced technology industries, the smart meter with microprocessor control, so that the temperature of the air to ensure that the air input granary within a set range from environmental factors.
2. Energy efficiency: Small power, low-power, high-efficiency, no warm-boot, do not need to store increasing passenger or transport circuit transformation
3. Cooling capacity: Cooling fan series, secondary cooling technology, the size of the air volume can be adjusted manually to meet the different granary, the needs of different cereal temperature.
4. While the system is running, the air does not accumulate in the lower condensation phenomenon does not occur due to the temperature difference is too large due to the grain temperature start upper drop to quickly reach a uniform temperature cooling effect.
5. Simple operation:
1) High efficiency design: Compressor series, cooling, high efficiency and low energy consumption.
2) Equipment hot air is discharged upward from the bad environment wind interference and ensure grain cooler to work efficiently.
3) Compact structure volume is small, light weight, flexible and easy to move. One person can move the installation. Performance of at least 50% higher than the same industry, after a set amount of wind speed control switch, the device can run automatically as required adjustment, simply set the air temperature.
6. Security protection: Machinery and equipment with automatic safety protection device, the fault alarm
Devices and fault code display, easy to find out the reasons, timely discharge fault.
7. Constant temperature & frequency conversion control. Make sure the outlet air temperature of each machine is the same.
The grain cooler cooling process:
>> Grain cooler cooling air through the ventilation pipe network into the grain, cereal calories in the cold negative pressure, cold air in a bottom-up process of the movement, to fully absorb, and then the hot air used granary the top of the axial fan is discharged outside the warehouse. The beginning of the grain bulk cold heart cold source, reduce the temperature of the top of the food continued cooler cold added to the cold heart, forming a loop cooling process. When grain heap need to control the temperature, the cooler off the end of the cooling process.
