Novel air-source dryer for powder food processing

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a novel powder food processing air energy dryer. Background technique [0002] With the rapid development of science and technology, energy saving and environmental protection have become an important indicator of the development of science and technology. The conservation and utilization of energy can reduce environmental pollution and save costs.

[0002] With the rapid development of science and technology, energy saving and environmental protection have become an important indicator of the development of science and technology. The conservation and utilization of energy can reduce environmental pollution and save costs. Nowadays, the energy on the earth is getting less and less, and the use of new energy can In line with the needs of modern technology, air energy should also be widely used. If air energy is used in the dryer, it can not only achieve a good drying effect, but also save energy and protect the environment. Traditional material dryers have belt drying , drum drying, box drying and tower drying, etc. The heat sources include coal, electricity, gas, etc. Whether it is industrial or civil, hot air box drying is one of them that is often used. Now Some hot air box dryers use the mode of blowing directly to the materials for drying, and the residual air of the hot air is directly discharged into the outside air, and the materials are easier to accumulate together in the drying box, so there will be many drying blind spots , so the existing hot air box dryer has relatively high energy consumption and relatively slow drying speed
