Our factory-made metal body TGJRF series of stand drum products are coal-fired hot air furnace heated indirectly by the China Design Institute of Agricultural Engineering Research, after upgrading to the five leading domestic level, and access to national patent technologies. The furnace used a set of combustion and heat for one to the furnace heat exchanger parts of the latest indirect heating technology. gas and air of the aisle, absolutely pollution-free heating, thermal efficiency as high as 65-80%, warming fast, small, easy to install , reliable, and low prices (compared with 1 ton boiler, the boiler heating system is only about half the price of heating system). Measures taken to high temperature, making it longer than tube stove greatly increased the output air temperature of 300 degrees, using a specially designed output air temperature can reach 500-800 degrees, while the vertical erosion by the smoke and heat sink exhaust from vacuum suction, no accumulation of dust and heat exchanger parts, no cleaning, thermal performance and stability. can use a variety of coal or firewood as fuel, and with a secondary air device, complete combustion. The furnace of the technical and economic indexes have reached the advanced level. 

 The furnace is the versatile hot air heating device, with a variety of materials supporting the use of drying equipment. Widely used in food, seed, feed, fruits, dehydrated vegetables, mushrooms, edible fungus, white fungus, tea, tobacco and other agricultural products, food, medicines, chemical raw materials, light and heavy industrial products, heating dehumidification. Can also be used for a variety of facilities, heating and dehumidification Treasury.
