Application scope：

▲This furnace is supported for each kind of material drying equipment as a kind of general hot air unit , which is widely used for dehumidification of cereal ,seed ,feed and fruit ,heating and wet extraction of vegetables ,mushroom ,Jew's-ear ,tea ,tobacco , food ,pharmaceutical products ,chemical raw materials and light and weight industrial products ,as well as for heating of various facilities and dehumidification of warehouses .

 Working principle：

▲Combining burning and heat exchange as a whole ,this furnace adopts the novel indirect heating technology of performing heat exchange at high temperature position of the furnace ,inside which, smoke and sir flow separately ,heating has no contamination ,thermal efficient reaches (60-75%)，therefore ,it features speedy temperature rise ,compact dimension ,convenient installation ,reliable operation and lower cost (only half of that by boiler heating system ).High temperature resistant measure is taken to extend its service life significantly in comparing with the tube still hot air furnace ,whereas ,cross brushing of heat sink by the smoke and negative pressure smoke exhaust are used to ensure a clean heat exchanging position with stable thermal performance .Fueled by any coal or firewood ,it is equipped with two phase air inlet unit ,which ensures sufficient combustion ,each technical and economical index of the furnace has reached the domestic leading level .
