Description
Technical field
The present invention relates to grain hot-blast furnace equipment technical field more particularly to a kind of efficient hot-airs for foodstuff drying device
Stove.
Background technology
It is well known that the temperature and humidity conditions in grain local environment meet microbial growth, will go mouldy.
That is moisture and temperature are two key factors of the microbial reproductions such as mould in grain.Grain water is controlled under normal circumstances
Dividing may prevent grain from going mouldy below safe moisture.Currently, the method for reducing grain moisture content is spontaneous combustion drying method.
Major grain producing area dries lack of space, often moisture exceeds safe moisture to the grain of grain depot purchase, is to cause since yield is big
The principal element that grain depot foodstuffs go mouldy especially just catches up with successive cloudy days in the grain purchases phase, even more so, in addition, being even put in storage
When grain moisture do not exceed safe moisture, but since spontaneous combustion is got damp, the grain of storage is also required to periodically dry, and just can guarantee
Grain does not go mouldy, and due to the limitation in the drying place of grain depot, the grain of storage tends not to dry on time, to cause grain depot grain
Food goes mouldy, and then, people dry the moisture in grain using dryer, since existing cereal drying technology is all using straight
The grain drying layer that the hot cigarette that fuel combustion generates is input to foodstuff drying device is connect, this mode that directly heats can make grain
At pollution, while the hot smoke temperature degree that fuel combustion generates is unable to control, and excessively high temperature can allow grain Decrepitation Phenomena occur.
