Description

Laminated grain direr

The utility model relates to a kind of drying equipment with water content in reduction grain, the oil plant, especially for grain storage department or oily factory soybean is given in the processing, needs low temperature precipitation to guarantee the laminated type grain drier of its baking back quality and purity.

Present storehouse of using is the Bath tower dryer now, adopting the direct-fired mixing wind of flue gas is medium, low humidity, high temperature, the dry soybean of flash baking method, because temperature height, make soybean produce a large amount of quick-fried waist grains, reduced grain quality and nutritive value, dry other Cereals also easily cause burnt stick with paste grain, half-cooked, overdo, make its pollution, degradation, devaluation; Above-mentioned drying tower is bulky, and floor space is big, the cost height; Coal consumption is big, and is main fuel with the anthracite, the cost height.Another kind of single layer hole plate current dryer, in the grain heat-drying process, precipitation range is little, and flow process is single, the high moisture content grain of inapplicable oven dry.Also having a kind ofly as U.S. Baily section type dryer, is fuel with diesel oil, is difficult to promote under the energy-intensive situation.

It is the oven dry thermal source with hot water that the purpose of this utility model provides a kind of, have the grain of maintenance edibility, thoroughly do away with and pollute, unlikely degradation devalues, and heat imitate high, power consumption less, cost is low, floor space is little, low temperature, preserve moisture, the slow laminated type grain drier of precipitation.

Drying equipment provided by the utility model is made up of body, heating system, conveying transmission system and four major parts of ventilation humidity discharging system.Body is welded into tower structure by shaped steel, reaches the top all around and is sealed by thermal insulation board, does not leak to guarantee the equipment heat, constitutes the casing of sealing, and two ends and middle part are provided with observation window, and there is charging aperture the top that is positioned at a side of casing, and there is discharging opening the below.Heating system is the groundwork part of this machine, is made up of the horizontal heated plate of multilayer that is fixed on the frame in casing.The heated plate empty stomach, mobile hot water is filled with in inside, with the in parallel or series connection of several pipeline valves control several layers heated plates, to regulate hot water flow, controls its temperature.And, heat is reached the material that is dried by heated plate.Carry transmission system by motor, decelerator, phoresy sprocket wheel, chain and wooden scraper plate and form, by motor, decelerator, drive, be transferred to two parallel bushroller chains and the pusher scraper plate that is fixed on therebetween through driving shaft, make it on each heated plate, promote material and move.The ventilation humidity discharging system is made up of circulating fan and moisture-eliminating blower.Circulating fan is fixed on casing top, is mainly used in to squeeze into material and give hot plate being distributed in the high temperature air that has certain humidity in the body, preserves moisture and gives heat.Moisture-eliminating blower is located at the casing end, mainly is outside the hot blast discharge machine that the inner water capacity of machine is bigger.

The dry run branch of entire equipment is preserved moisture and is given heat, heat drying and ventilation cooling three phases.Its operation principle is: after materials such as grain entered feed arrangement, being scattered in the overall with scope rapidly by feeding roller fell into heated plate, and the promotion of nationality chain scraper is slowly advanced, and obtained upset in dull and stereotyped terminal.The grain layer of being close to heated plate is because the heat conduction, progressively heat up and the discharge water branch, top layer grain is subjected to the heat transmission of bottom humid air on the one hand, be subjected to brushing of circulating fan hot-air on the other hand, humidity discharging simultaneously heats up, but because the upper strata is to be in the situation of preserving moisture and heating, therefore material surface water evaporates has certain limit, the material particles internal and external temperature is balanced to rise thereby reach, moisture content relaxes the purpose of evaporation, the phenomenon of particle epidermis hot tearing (dry and cracked) is suppressed, and this is necessary when giving temperature.Enter heat drying after the stage, this moment, temperature of charge rose little, the heat that adds is mainly used in the material water evaporates, and the hot blast main purpose that is blown into is used to provide heat, the heating upper materials, and the nationality hot blast flows, take away the bigger humid air of water content, the hot-air humidity that therefore middle lower floor is blown into should slightly reduce, and the dryer section below is depositing the comparatively saturated humid air of moisture content, no longer include value, outside moisture-eliminating blower discharge machine.Material is the dry humidity discharging through certain hour in this stage, is promptly discharged by the bottom, enters another tempering cooling stage.

The laminated type grain drier has the following advantages compared with the prior art:

1, adopts the indirect mode, the thermophores such as material and flue gas that are dried are disengaged, avoid polluting.

2, employing is the most cheap, and the water that is available anywhere is as thermophore, and recycling, improves heat and imitates, and reduces cost.

3, utilize the high humidity hot blast, give the heat material that is dried, prevent the too fast loss of its epidermis moisture content, crack, rupture, and reduce use value.

4, adopt low temperature, middling speed to relax dry method, keep the edibility such as fresh, good to eat of material such as grain.Suitably improve, also can be used for needing to keep the seed drying of germinating capacity.

5, make full use of waste gas residual heat and give warm material, improve the thermal efficiency, cut down the consumption of energy.

Therefore this suitable novel material such as equipment drying grain that provide has the grain of maintenance edibility, good to eat degree, thoroughly does away with and pollute, and the advantage of unlikely degradation devaluation, compare with same category of device, also have superiority such as thermal efficiency height, less energy consumption, cost are low, work situation improvement.
