Abstract

The invention provides a bidirectional pneumatic ball-type grain air-drying device and a double ball-cage drying method. In existing grain drying, burning fuels are needed to supply a heat source, a fan blows hot air into a grain drying box, and grains are turned over by a mechanical device and then dried. A drying device in a traditional method is complicated, large in occupied space and high in price, and a small peasant household cannot afford the drying device. The air-drying device comprises a dryer (1) and a drying fan (2) mounted in the dryer, the outer surface of the dryer is spherical, a spherical drying cage (3) is fixedly mounted inside the dryer through a frame (6), the drying fan is mounted between the dryer and the spherical drying cage, a grain inlet (4) is arranged on the upper portion of the dryer, a grain outlet (5) is arranged on the lower portion of the dryer, and a support (7) is arranged at the bottom of the dryer. The air-drying device is used for drying grains of small and medium-sized rural cooperative organizations.

Description

Wind-force crop dryer and two ball cage drying means

Technical field:

The present invention relates to the air-dry drying equipment of a kind of two-way wind ball formula grain and two ball cage drying means.

Background technology:

Grain is as a kind of live body life, if put in the wet environment, moisture around one-tenth branch in the grain absorbs, cause grain expansion, heating, germination, infested, phenomenon such as go mouldy, can not eat and use, cereal is after cleaning in the conventional treatment, deliver to the drying machine grain storage section by elevator, automatically control upward grain by level detector, grain traffic direction in drying machine becomes cross-flow with hot blast (cold wind) flow direction, realize the whole process of preheating, drying, commutation, drying, cooling, discharge through rubber conveyer by discharge zone at last.Grain is shed, is disperseed, is suspended, is moved forward under motion state, and carries out heat exchange in the time of setting.In the existing grain heat-drying, the combustion fuel supplied heat source need be arranged, by blower fan hot blast is blown in the grain drying case, by plant equipment rolling grain, carry out drying.

The drying equipment complexity of conventional method, occupied ground is big, the price height, small-sized peasant household can not purchase.

Summary of the invention:

The present invention relates to a kind of wind-force crop dryer, reduce floor space, improve drying effect.

The object of the present invention is achieved like this:

A kind of wind-force crop dryer, its composition comprises: dry body, be installed in the drying air fan in the described dry body, described dry body is that outer surface is spherical, spherical dry cage is equipped with in described dry body inside, described drying air fan is contained between described dry body and the dry cage of described sphere, and the top of described dry body has grain-entering mouth, and the bottom of described dry body has the mouth of putting out cereal.

Described wind-force crop dryer, described dry body have uniform warp-wise skeleton and one group of broadwise skeleton, and the dry cage of described sphere has uniform interior warp-wise skeleton and one group of interior broadwise skeleton, and described drying air fan is two-way same sex axial flow blower.

Described wind-force crop dryer, outer screen is equipped with in the inboard of described warp-wise skeleton broadwise skeleton, and nexine screen cloth, described outer screen and described nexine screen mesh diameter 1-3mm are equipped with in described interior warp-wise skeleton and the described interior broadwise skeleton outside.

The method of wind-force dried grain, its composition comprises: adopt above-mentioned wind-force crop dryer, wind-force is adjusted at 1000m ³ / t/h, when environment temperature at 5 degrees centigrade, ambient humidity is less than under 40% the situation, the commutation of every 10-30 minute drying air fan turnover wind wind direction once, input grain suitable for reading from dry body, grain is between two-layer spheroid, when drying air fan is blown into dry wind to the dry cage of sphere, wind-force sees through nexine screen cloth-grain-outer screen and carries out drying, and when drying air fan was outwards extracted the dry cage dry wind of sphere out, wind-force saw through outer screen-grain-nexine screen cloth and carries out drying, through 10 hours, moisture 20% paddy rice moisture reduces 3-5%, moisturely reaches 13% o'clock drying and finishes, and emits from the end opening of dry body.

Beneficial effect:

1. pneumatic dryer of the present invention directly uses the big air quantity of natural wind to dry up material.Material is between outer screen and inner screen, when drying air fan is blown into dry wind to the dry cage of sphere, wind-force sees through nexine screen cloth-grain-outer screen and carries out drying, when drying air fan was outwards extracted the dry cage dry wind of sphere out, wind-force saw through outer screen-grain-nexine screen cloth and carries out drying.The variation of wind direction hockets, to improve drying effect and the dry uniformity.

2. pneumatic dryer of the present invention does not have the air link of heating, and has saved fuel cost.Because adopt normal temperature to handle, the grain quality after the processing obviously is better than drying the quality of heat drying furnace cereal.

3. the present invention adopts two-layer wind ball design, and floor space is little, and cost is low, and suitable peasant household takes care of the drying of grain voluntarily, has reduced middle warehousing costs, has reduced whole commodity food price.
