Heat conducting pipe is conveyed into burning heater or boiler, and burning heater or boiler give heat-conducting medium heating again, heat-conducting medium week and
Heating, heat dissipation, heating, the heat dissipation renewed.
The heating device is fixed on grain harvesting machine, and heating device and grain harvesting machine are connected to one.
1, the fuel used in burning heater or boiler is oil entrained in corn mowing machine top tank;Either lay in
Other fuel on corn mowing machine.
A kind of the grain dry principle and particular advantages effect of cereal vacuum dryer.
1, vacuum dehydrating at lower temperature is exactly that will be placed in closed dryness storehouse by dry wet cereal, steamed using moisture vaporization
The principle that temperature is reduced with environmental pressure reduction is sent out, cereal vacuum dryer is true in dryness storehouse during drying cereal
Reciprocal of duty cycle optimal setting is -0.025 Mpa to -0.098Mpa, and the low temperature drying of 36~60 DEG C of realization is to paddy under vacuum conditions
Object is dried.While being vacuumized with vacuum pump set, heat-exchanger rig to being heated by the continuous thermal conductivity of dried grain, dryness storehouse
Vacuum degree gets over that high air resistance is small in storehouse, and the thermal energy supply of the three-dimensional heat exchange thermal conductivity of heat-exchanger rig is abundant in dryness storehouse, in cereal
Moisture vaporization rate with regard to fast, the boiling point of moisture is lower in cereal, and the vaporization rate of moisture is faster, makes the water inside cereal
Divide and surface is diffused by pressure difference or concentration difference, hydrone obtains enough kinetic energy on cereal surface, intermolecular overcoming
It after attraction, escapes into the low-pressure air of dryness storehouse, to take removing away by vacuum pump set, has reached the quick vacuum of cereal
The purpose of low temperature drying.
2, in cereal vacuum dryer dried grain heat-conducting medium " heat conducting pipe, heat-exchanger rig, heating device " envelope
Cycling and reutilization in system is closed, such as 80 DEG C of heat-conducting medium after heat conduction and heat radiation, returns to heating device in heat-exchanger rig
The temperature of heat-conducting medium can also reach 50 DEG C, and heat-conducting medium is heated to required 80 DEG C, only 30 DEG C of the temperature difference, such institute
The thermal energy needed is just much less, and the effective rate of utilization increase of thermal energy is very big.Heating device is by heat-conducting medium directly to cereal
Heat conduction is heated, and thermal conversion efficiency is high and loss is small;The heat exchange area of the three-dimensional heat exchange of dryness storehouse inner heating device increases 12-
30 times, the heat conduction heat transfer rate under vacuum state is improved, the thermal energy transmission total amount for drying cereal is improved;Heat-conducting medium exists
Cycling and reutilization improves having for the thermal energy on grain harvesting machine in the closed system of " heat conducting pipe, heat-exchanger rig, heating device "
Imitate utilization rate.
3, the energy consumption index of vacuum conductive drying is 2800-4000kj/kg, and the energy consumption index of hot air convective drying is
5500—7500kj/kg;The thermal energy availability of hot air convective drying generally only 20-50%, and vacuum conductive drying
Thermal energy availability in theory can be close to 100%, and actually the thermal energy availability in vacuum conductive drying device can
To reach 60-80%.Vacuum conductive drying is more energy saving by 30-50% than hot air convective drying under normal circumstances, this is because vacuum passes
It leads drying and does not need Hot-blast Heating material, it is small by the thermal losses for being vented lost, in constant speed drying section, due to vacuum or decompression drop
The low boiling point of water, material heating is minimum, and heat almost all is used for evaporating hygroscopic water, such as close or be less than critical moisture content
When, the power savings advantages of vacuum conductive drying are bigger;The availability height of Vacuum Heat conduction heat transfer solves on grain harvesting machine
The small problem of thermal energy supply.
When grain harvest, successive cloudy days are easily encountered, the cereal after harvest cannot dry drying in time, and paddy is resulted in several days
Object plays heat, goes mouldy.
1,35-25% when the cereal vacuum dryer on grain harvesting machine will be harvested using vacuum drying technique
The cereal of water content is dried.
2, in the case that drying time of the cereal in dryness storehouse is 15-30 minutes, the water content of cereal can be dried
It is reduced to 21-19%.
3, in the case that drying time of the cereal in dryness storehouse is 30-120 minutes, the water content of cereal can be dried
It is dry to be reduced to 16-14%.
The present invention has the advantages that compared with existing cereal kernel cropper:The structure letter of cereal vacuum dryer
Single, equipment volume is small, low manufacture cost, and heat insulation effect is good;Cereal kernel cropper is mixed cereal vacuum dryer and can be harvested
The cereal of harvest is dried while cereal, the heat-conducting medium that thermal energy is carried in cereal vacuum dryer passes through heat-exchanger rig
Directly to cereal conduction heating, the heat-exchanger rig in dryness storehouse is three-dimensional heat exchange heat conduction, and thermal conversion efficiency is high and loss is small, improves
Heat conduction heat transfer rate, accelerates the rate of drying of cereal.
