The present invention discloses a novel air-source dryer for
powder food processing. The novel air-source dryer comprises a
drying box and a box body. A feeding funnel is disposed on an upper end of the
drying box. A feed hopper is disposed on an upper end of the
drying box. Feed inlets are symmetrically disposed at two sides of an extension end of the feed hopper, and both connected with spiral material pipes. The ends, far away from the feed inlets, of the two spiral material pipes are connected with a
discharge pipe. The two spiral material pipes surround a first drying cylinder and a second drying cylinder, respectively. A plurality of vent pipes are connected between the first drying cylinder and the second drying cylinder. An upper end of the first drying cylinder communicates with a blast
pipe, and the end, far away from the first drying cylinder, of the blast
pipe extends into the box body. A compressor, a condenser, a throttling device and an
evaporator are disposed in the box body. The end, extending into the box body, of the blast pipe communicates with the condenser. The novel air-source dryer for
powder food processing is simple in structure, easy to operate, good in
powder food drying effect, and not prone to accumulation; and the device is convenient and smart in use, and suitable for extensive promotion.
