Description
Technical field
The present invention relates to one repeatedly dedusting foodstuff drying device, belong to Cereals Processing Machines equipment technical field.
Background technology
Grain is human lives's necessity, and various countries all pay much attention to grain-production deposit.But before receipts grain puts in storage, because weather or other reason large portion grain do not dry and moldy metamorphism immediately, not only affect grain quality and also potential harm is present in other health.The grain moisture content of new harvesting is generally at about 17%-32%, and the safe moisture of grain storage, about 14%, can store if therefore need safety stock grain must reach safe moisture to grain precipitation.At present, carry out drying mainly adopt following several method to grain, one is the method adopting the sun to be exposed to the sun; Two is the methods adopting fixing warehouse for drying, in use all there is following deficiency in two kinds of methods, first, adopt the method that the sun is exposed to the sun, although cost is lower, but this method is limited to weather and place, so, use inconvenience; And use the method for warehouse for drying, although can not by the restriction of weather, the one-time investment of warehouse for drying be comparatively large, and meanwhile, warehouse for drying is when oven dry amount is less, and its cost run is also higher.
The generic way that current world food is dried adopts vertical grain drying tower.Its thermal source generally comes spontaneous combustion coal, fuel oil, combustion rice husk, stalk, and fuel produces hot blast through Combustion of Hot Air Furnace, hot blast is passed into grain heap, by grain heat-drying.This drying mode shortcoming is more: general about 150 DEG C of the flue gas after fuel combustion, directly enters air, and the flue gas of heat does not utilize, and produces energy waste.It is shorter that hot blast passes the silo time, generally about a second, exchanges thorough, be with the air of temperature of having a surplus directly to enter air and cause energy waste after exchanging.The air simultaneously extracting temperature lower from air again heats.For my north, dry season generally in the winter of cold, outdoor temperature, at about-20 DEG C, extracts-20 DEG C of air and heats, again the gas of about 40 DEG C above freezing is entered in air after heat exchange, and waste is serious.Traditional tower oven dry hot blast needs to penetrate 60-80cm grain heap, and hot blast can produce very large resistance through during grain heap, and energy loss is larger.Traditional tower oven dry operation energy consumption is very large, and drying its general power of 500T drying tower day is 255kw, is all operate power, is mainly used on blower fan, elevator, does not produce oven dry heat.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of repeatedly dedusting foodstuff drying device of good drying effect.
The present invention is the technical scheme solving the problems of the technologies described above proposition: one is dedusting foodstuff drying device repeatedly, comprise conveyer belt, at least one hot blast shower nozzle, warehouse for drying, air-heater, hot air duct, coil pipe and boiler, described conveyer belt surface is latticed, described air-heater is communicated with described hot blast shower nozzle by hot air duct, described hot blast shower nozzle is positioned at above described conveyer belt, disposal box is provided with below described conveyer belt, described disposal box has vavuum pump by pipeline connection, described conveyer belt one end is provided with aggregate bin, and described aggregate bin is connected with auger; Described warehouse for drying is provided with grain-entering mouth and grain outlet, and described air-heater is communicated with warehouse for drying by hot air duct, and the air outlet of described air-heater is provided with corona discharger, and described coil pipe is arranged in warehouse for drying, and described boiler is communicated with by hot water pipeline with coil pipe; The discharging opening of described auger is communicated with described grain-entering mouth.
The improvement of technique scheme is: the discharging opening of described auger is provided with outlet valve.
The improvement of technique scheme is: described warehouse for drying top is provided with air outlet.
The improvement of technique scheme is: described grain-entering mouth is at least one.
The improvement of technique scheme is: described air-heater is at least two.
The improvement of technique scheme is: described warehouse for drying outer surface is enclosed with heat-insulation layer.
The improvement of technique scheme is: described hot air duct outer surface is enclosed with heat-insulation layer.
The improvement of technique scheme is: described hot water pipeline outer surface is enclosed with heat-insulation layer.
The present invention adopts the beneficial effect of technique scheme to be: 1) owing to being dried the grain in warehouse for drying together with coil pipe by air-heater, combine the advantage of air-heater and coil pipe, and make drying effect better, drying efficiency is higher; 2) because the air outlet of air-heater is provided with corona discharger, this corona discharger ionized air forms gas ions, takes arrival warehouse for drying out of by air-flow, with electrostatic and dedusting object in reaching; 3) because warehouse for drying outer surface is enclosed with heat-insulation layer, the heat loss in warehouse for drying can be prevented; 4) because hot air duct outer surface is enclosed with heat-insulation layer, the heat loss in hot air duct can be prevented; 5) because hot water pipeline outer surface is enclosed with heat-insulation layer, the heat loss in hot water pipeline can be prevented; 6) due to by drying the secondary drying adding warehouse for drying during conveyer belt, make to dry more thoroughly efficient; 7) owing to being provided with disposal box below conveyer belt, described disposal box has vavuum pump by pipeline connection, grain can be sucked disposal box through conveyer belt by the dust that hot blast shower nozzle blows out, reach the effect of repeatedly dedusting.
