In the grain drying process, the most commonly used is the grain dryer radiator. Due to the high temperature and humid environment in the south, it is suitable for the growth of grain storage pests and mites, and the prevention of grain storage pests and mites has become an important issue in the south of grain storage;

The temperature in the north is low, and there are four or five months of freezing in a year, sometimes spring drought, summer flood, and autumn early frost. Therefore, the key to the north is to prevent water from mooring. Therefore, there is a grain storage law of "controlling insects in the south and mooring water in the north". Therefore, dry food has become an important part of insect control and anti-mooring water.

1. Features of Grain Dryer Radiator

1. Cost saving: the price is much lower than that of the hot blast stove, and its performance-price ratio is high;

2. Meticulous processing: advanced processing technology, strict quality assurance system, strict organization, and meticulous processing;

3. Easy installation: installation, use, and maintenance are simple and convenient, and the labor intensity is low;

4. Rolling process: The finned tube adopts the overall rolling process, no contact thermal resistance, high strength, thermal shock and mechanical vibration resistance, good thermal expansion performance, and considerable heat transfer surface. The heat exchanger made of this kind of finned tube has the effect of serial fin or wound fin heat exchanger.

2. Working principle of grain drying radiator

The grain drying radiator is composed of a perforated plate frame and a heat exhaust pipe groove. The heat exhaust pipe groove is fixed and installed by the frame, with close contact and good heat dissipation performance. Using steam or hot water as hot coal, its working principle is as follows:

When the hot coal passes through the finned tube base tube, the heat is transferred to the fins by heat conduction, and then the air is heated by heat transfer and forced convection to achieve the purpose of dry food.

The above are the characteristics and principles of the grain dryer radiator.
