Description
Technical field
The present invention relates to grain drying equipment fields, and in particular to a kind of suction type roller drier.
Background technology
Bread is the staff of life, and grain is lived in peace originally as the people, is one of national grand strategy material for preparedness against war always.By
Still containing a large amount of moisture in the grain by traditional dryness in the sun, usually storage is no more than 1 year and can go mouldy or germinate,
The rainwater weather more frequent time is above-mentioned or even shorter.If running into continuous unusual weather conditions, grain drop in production, grain stocking
Amount also can significantly atrophy, this does not obviously meet the positioning of the strategic material for preparedness against war of grain.Therefore, drying is now mostly used at present to replace
In generation, dries to be further reduced the water content of grain, to further extend the period of storage of grain, to meet as strategy war
The demand of standby goods and materials.
As the core equipment of drying process, the performance of drying machine directly determines the excellent of grain drying technology.The most
Common drying machine mostly uses cartridge type or pot type structure.But in practical practical process, due to being structure in sealing or semitight
In, as the moisture in grain gradually steams, the moisture in drying receptacle is higher and higher, and humidity is increasing, to shadow
Ring to residual moisture in grain and steam, cause after drying Measurement for Grain Moisture Content it is still higher.Further, since container
Interior moisture is not discharged in time, when grain cooling down, easily causes the phenomenon that getting damp, that is, the grain weight after drying
It newly absorbs the moisture in container and gets damp again.
Invention content
The present invention provides a kind of suction type roller driers, are asked with solving to get damp caused by moisture in drying receptacle is excessively high
Topic.
The technical solution adopted by the present invention is as follows：
A kind of suction type roller drier, including pedestal, the holder being mounted on the base and pass through shaft Cheng Xuan with holder
Turn the drying cylinder of cooperation；Feed opening is provided at the top of the drying cylinder, bottom is equipped with discharge port；The shaft is provided with axis hole；
It is integrated with heating layer in the drying cylinder barrel；Ventilation duct with hollow structure is installed in the barrel chamber of the drying cylinder；Institute
Ventilation duct both ends are stated to stretch out axis hole and be pierced by holder；The ventilation duct, which is located on the tube wall inside drying cylinder, is provided with ventilation hole.
The operation principle and process of the technical program are as follows：
When the grain of drying in need, grain is gone out to be added in drying cylinder from feed inlet, is added in dry mouth
Grain is by being arranged the heating layer heat temperature raising in wall inner portion, to make the moisture in grain is heated to evaporate
Come, has reached dry purpose.At the same time, cold air is dried by flow at high speed in hollow ventilation duct.When air height
When speed flowing, the surface that air flows through can form strong negative pressure.Pass through the ventilation hole being provided on ventilation duct, suction function conduction
Into drying cylinder, to make the wet air extraction for also having grain to steam moisture in drying cylinder so that in drying cylinder not
Have the siltation of vapor.In this way, during cooling down, due to the dry environment in drying cylinder, would not exist
Grain leads to the problem of moisture regain because reuptaking the moisture that its own is evaporated, it is ensured that grain is dried final
Effect.In addition, due also in drying cylinder there are negative pressure and humidity it is relatively low, reduce the boiling point of moisture, increase environment and grain
Intergranular psychrometric difference.Under the common promotion of the two, the degree of drying of grain is improved, rate of drying is accelerated, is contracted
The short dry required operating time.
In drying process, it can realize that the stir-frying to grain acts on by tumble dried cylinder, can be promoted in this way
Grain is heated evenly degree, while preventing from heating part grain always and cause temperature excessively high and that causes burn risk.
At the end of drying, heating layer is made to be stopped, while keeping constant ventilation in ventilation duct, then waits for grain
Gently natural cooling.Due to reduction of fractions to a common denominator pipe constant ventilation, always be in a state of negative pressure in drying cylinder, in this way in the state of, it is dry
Remaining a small amount of vapor remains its dispersity in cylinder, to agglomerate to and can be reuptaked by grain
Degree eliminates the problem of grain cooling gets damp again.
Further, described ventilation duct one end is provided with drying device；The drying device includes drying box and is set to
Air inlet on drying box；Drier is filled with inside the drying box.By the effect of drying device, reduces and flow through ventilation
The humidity of air inside pipe, it is poor with drying cylinder interior humidity inside ventilation duct to have widened.It is pushed in the physical action of psychrometric difference
Under, the moisture in drying cylinder is more easy to escape into ventilation duct to be carried over by ventilation hole, further reduced in drying cylinder
Humidity reduces the moisture regain degree of grain in follow-up cooling step.
Further, the diameter of the air inlet is more than the diameter of ventilation duct.Pass through resistance when drying box due to air
Power is larger, and flow velocity decreases, therefore by the design of air inlet size, drying box is made to be attached to the function of supercharging device,
The colleague of its resistance is offset, keeps or promoted air by flow velocity after drying box, to ensure that it is to generate to flow through ventilation duct
Vacuum effect.
Further, the heating layer is any one of microwave heating layer or resistance heating layer.Using above two side
Formula, homogeneous heating degree is good, quick heating, is effectively shortened the operation duration of drying process.
Further, the heating layer is microwave heating layer.Microwave heating is by microwave directly to grain inside
It is heated, the efficiency of heating surface is high, has good energy-saving effect, and strengthen the movement of hydrone, and more conducively hydrone is from grain
It eats and is detached from inside particle.
Further, it is provided with material taking mouth on the discharge port.It, can in the drying process at any time by increasing material taking mouth
To the sampling analysis of grain, the monitoring to grain degree of drying is realized, is conducive to sentence the accurate of dry terminal
It is disconnected.
In conclusion the advantageous effect of the present invention compared to the prior art is：
(1) humidity and pressure that can be effectively reduced in drying cylinder accelerate the discharge of grain internal moisture；
(2) moisture that air in drying cylinder can be detached, grain water suction moisture regain when preventing cooling；
(3) drying cylinder can rotate, and realize the stir-frying to grain, and improve grain is heated evenly journey
Degree, avoids and burns, goes bad because local temperature is excessively high；
(4) analysis can be sampled to the grain in drying cylinder, to accurately hold the terminal of drying process, into
And ensure the dry mass of grain.
