Abstract

The utility model provides a device for drying foods. The device is easy to manufacture, can uniformly dry the foods, is low in crushing rate, and has zero mechanical energy consumption. The device comprises a material inlet, a drying bin and a material discharging port, wherein the material inlet is formed above the drying bin; and the material discharging port is formed below the drying bin. The device is characterized in that: the drying bin has a tapered shape with a large upper part and a small lower part, and comprises an inner tapered sieve, an outer tapered sieve and a dustproof protection cover which are arranged coaxially; sieve pores are densely formed in the inner tapered sieve and the outer tapered sieve; and the material discharging port comprises a material outlet and an impurity outlet.

Description

A kind of grain drying device

Technical field

The utility model relates to a kind of drying unit of grain.

Background technology

Present drying plant generally includes grain storage layer, baking zone and discharge layer; The grain storage layer is arranged on the top of baking zone; Baking zone is a square structure; The baking zone below is provided with the discharge layer, and the same section of said discharge layer is provided with a plurality of discharge mechanisms, below a plurality of discharge mechanisms, is provided with total discharge mechanism.There is following shortcoming in this mechanism: 1, guarantee that surely its running status is unified because a plurality of discharge mechanisms differ when fabrication and installation, cannot say for sure to demonstrate,prove grain can evenly descend, and this just influences the drying effect of material, and the final moisture content unevenness increases.2, because of repeatedly receiving the mechanical rotation effect, material is broken because of a large amount of extruding increase, and has a strong impact on baking back quality.3, also need carry out material and impurity separating treatment after the oven dry, increase the consume of the labour intensity and the energy.

Summary of the invention

The utility model provides a kind of grain drying device, makes simply, can make that grain is evenly dried, percentage of damage is low, and not have mechanical energy consumption.

For addressing the above problem, the utility model is achieved in that

A kind of grain drying device comprises charging aperture, the oven dry storehouse; Discharge gate, said charging aperture are arranged on top, said oven dry storehouse, and said discharge gate is arranged on below, said oven dry storehouse; It is characterized in that the taper that said oven dry storehouse is big up and small down comprises that inner conical sieve, the male-tapered of coaxial setting sieved and dust cover; Be densely covered with sieve aperture on said inner conical sieve and the said male-tapered sieve, said discharge gate comprises material outlet and impurity outlet.

As the further optimization of the utility model, the rounded or polygon in cross section of said inner conical sieve, male-tapered sieve and dust cover.This regular shape, easily manufactured.

The beneficial effect of the utility model is embodied in:

1, coaxial setting has guaranteed that the time that grain contacts with hot blast is identical, thereby precipitation range equates, has improved the water uniformity after the grain baking.

2, pyramidal structure makes grain can rely on gravity just can discharge outside the baking zone, need not to be provided with power.

3, grain effectively reduces the fragmentation of grain not through mechanical agitation and high-speed friction, has guaranteed the quality of oven dry grain.

4, be provided with dust cover, reduce environmental pollution, impurity gets into the annular space of male-tapered sieve and dust cover formation with air-flow, discharges from the impurity outlet afterwards.

Wherein: charging aperture 1, oven dry storehouse 2, inner conical sieve 3, male-tapered sieve 4, dust cover 5, sieve aperture 6, material outlet 7, impurity outlet 8.

The specific embodiment

Do below in conjunction with 1,2,3,4 pairs of the utility model of accompanying drawing and to further describe:

A kind of grain drying device comprises charging aperture 1, oven dry storehouse 2; Discharge gate, said charging aperture 1 are arranged on 2 tops, said oven dry storehouse, and said discharge gate is arranged on 2 belows, said oven dry storehouse; It is characterized in that the taper that said oven dry storehouse 2 is big up and small down comprises inner conical sieve 3, male-tapered sieve 4 and the dust cover 5 of coaxial setting; Be densely covered with sieve aperture 6 on said inner conical sieve 3 and the said male-tapered sieve 4, said discharge gate comprises material outlet 7 and impurity outlet 8.

As the further optimization of the utility model, the rounded or polygon in cross section of said inner conical sieve 3, male-tapered sieve 4 and dust cover 5.This regular shape, easily manufactured.

During work, material is got in the drying channel that inner conical sieve 3 and male-tapered sieve 4 constitute by charging aperture 1, relies on gravity evenly to flow, and is discharged by discharge gate again.Hot blast gets into oven dry storehouse 2, under the effect of hot-blast pressure, passes inner conical sieve 3 and gets in the drying channel, and discharge from male-tapered sieve 4.Accomplish the wet exchange of heat when hot blast passes drying channel, take away grain moisture content and impurity.Grain flows from top to bottom, accomplishes grain heat-drying.Because inner conical sieve 3 sieves 4 coaxial settings with male-tapered, guaranteed that the time that grain contact with hot blast is identical, thereby precipitation range is equal, has improved the water uniformity after grain dries by the fire.Because oven dry storehouse 2 big up and small down pyramidal structures make grain can rely on gravity just can discharge outside the baking zone, need not to be provided with power simultaneously, grain effectively reduces the fragmentation of grain not through mechanical agitation and high-speed friction, has guaranteed the quality of oven dry grain.

The utility model is not limited to the foregoing description, and the cross section of said inner conical sieve 3 and male-tapered sieve 4 can also be regular polygon.
