Description

Cereal vacuum circle-type drier
Technical field
The present invention relates to a kind of vacuum drying apparatus, especially a kind of cereal vacuum circle-type drier.
Background technology
At the beginning of the fifties, China has introduced corn series dehydrator, drying tower (room) from the former Soviet Union, has carried out the state of drying tower Productization design and manufacture, although form is a lot, but basic structure is substantially the same.Drying tower all uses high temperature high wind to dry, and is dried Technological process is that the hot blast of following current, adverse current and mixed flow carries out grain-drying.It exists that drying plant volume is big, outside heat exchanger tower Heat exchange wind, heat energy energy loss is big, and hot blast is disposable utilization rate, and heat utilization rate is low, and hot blast power consumption is big, and waste heat obtains not To problems such as utilizations.Dried grain quality is poor, and drying time is long, and drying temperature is wayward, and dried corn is broken, quick-fried Waist and severe crack, cause intermediate links loss to increase.Described corn refers to Semen Maydis, Oryza sativa L., Semen Tritici aestivi, Semen sojae atricolor, miscellaneous grain crops etc. The seed of cereal crops.
Vacuum drying technology on market is the most ripe, carries out vacuum dehydrating at lower temperature to material under the vacuum state of low pressure, solves Hot blast temperature of having determined is high, inferior problem after drying materials.Now it is desirable that the low-cost and high-quality for corn is dried offer A kind of brand-new solution, has the strongest market competitiveness.
Summary of the invention
The present invention is to provide a kind of cereal vacuum circle-type drier, it is capable of persistently promoting stirring, improves dry Efficiency, optimizes drying effect;Heat exchanger is directly to corn heat conduction, heating, thermal conversion efficiency height and low-loss, heat supply temperature For 180--300 DEG C, the moisture vaporization boiling point of corn is at 30--58 DEG C;Expand heat conduction and heat radiation speed, the heat energy transmission of drying Total amount is improved;Corn cold drying is uniform, and drying rate is fast, energy-conserving and environment-protective.
For reaching above-mentioned purpose, the present invention adopt the following technical scheme that a kind of cereal vacuum circle-type drier by lifting device, Warehouse for drying, condenser, vacuum pump, heater, heat-exchanger rig, material inlet valve, discharge valve, delivery device, ventilation dress Put, support, airway form.
The lower end of described warehouse for drying is fixed support by support.
The metal warehouse that described warehouse for drying is fabricated to by metallic plate, the upper and lower side of warehouse for drying is taper;The section of warehouse for drying is Square or circular.
Described one end below warehouse for drying is provided with discharge valve;The side of warehouse for drying overlying one end is provided with material inlet valve, The centre of warehouse for drying overlying one end is provided with lifting device.
1, material inlet valve is the passage that material enters warehouse for drying;Discharge valve is the passage that warehouse for drying discharged by material.
2, material inlet valve and discharge valve are valves, or high airtight discharge gate, or vacuum valve.
3, material inlet valve and discharge valve play the effect closing warehouse for drying.After corn enters warehouse for drying by material inlet valve, envelope Start to dry corn after closing material inlet valve;Grain-drying opens discharge valve after drying, and corn just can utilize self gravitation to drop Discharge warehouse for drying.
Described lifting device is that corn is so followed by above in the storehouse inner bottom part cereal hoisting of warehouse for drying to the storehouse of warehouse for drying Ring turns, and is sufficiently stirred, and corn has obtained uniformly being dried.
1, in lifting device is mounted in warehouse for drying storehouse, or it is arranged on the outside of warehouse for drying.Lifting device and warehouse for drying Junction want fixing seal, it is impossible to enough gas leakage;Corn under the castering action of lifting device, corn in warehouse for drying in up and down Cycle balance stirs.
2, lifting device is bucket elevator, or auger elevator.
The middle position, lower end of described warehouse for drying is provided with delivery device, and the effect that delivery device is played is by warehouse for drying storehouse In the decline of corn uniform plane, corn so can be made to be heated, uniform drying.
Heat-exchanger rig and exhaust apparatus are installed in the storehouse of described warehouse for drying.
1, heat-exchanger rig is heat exchange of heat pipe, or tubular heat exchanger.Heat-exchanger rig by heat energy Homogeneouslly-radiating in dryness storehouse, The heat energy providing enough it is dried to the water vapor of corn.
2, exhaust apparatus is the exhaust apparatus of vacuum drying tower, or recycle stream ventilation exhaust apparatus, or tubulation aerofluxus Device.The corn thickness stacked in warehouse for drying storehouse is very big, and poor air permeability, so needing exhaust apparatus to penetrate corn heap, corn In dampness can eject smoothly.
Warehouse for drying is extended in the heat-exchanger rig outlet of described heat-exchanger rig and heat-exchanger rig import;Heat-exchanger rig import is connected to Heater, heat-exchanger rig outlet is connected to heater.
1, the heat-exchanger rig that heat energy produced by heater is transmitted in warehouse for drying by airway by heat-conducting work medium, heat conduction Working medium is entered in heat-exchanger rig by heat-exchanger rig import.
2, after heat-conducting work medium dispels the heat in heat-exchanger rig, through the outlet of heat-exchanger rig, it is again introduced into heating by airway Again heating in device, the circulation of such heat-conducting work medium is heated always, dispels the heat, heats, is dispelled the heat.
Described heater is air stove, or boiler, or burner, or heat pump device.
Described heat-conducting work medium is gas or water or conduction oil.
After warehouse for drying is extended in the outlet of described exhaust apparatus, the outlet by exhaust apparatus of the dampness in warehouse for drying, through leading Trachea, condenser, airway, vacuum pump are discharged in air.
1, condenser plays the effect that dampness is condensed into water and gas.Volume-diminished 60--90% after dampness condensation, is configured The power of vacuum pump will reduce a lot, energy-saving and emission-reduction.
2, vacuum pump plays the moisture exhausting in warehouse for drying storehouse, the effect of evacuation.Vacuum in warehouse for drying storehouse is by vacuum The pump drainage of pump controls, and makes the vacuum in warehouse for drying storehouse reach the vacuum required for the boiling point of 30--58 DEG C of water.
The present invention compared with prior art has the advantages that: the cereal vacuum circle-type drier that the present invention provides, its energy Enough realizations persistently promote stirring, improve drying efficiency and optimize drying effect;Heat-exchanger rig directly to heat grain, heat conduction, Heat radiation, in heat energy, cycling hot conversion efficiency is high and is lost little, expands heat conduction and heat radiation speed, improves drying temperature, reduce The boiling temperature of moisture, so shortens the corn drying time, makes grain-drying uniform moisture, and the grain quality after drying is entered The raising of one step.
