Description
Technical field
The utility model relates to a kind of dryer, particularly relates to a kind of grain drying machine.
Background technology
Paddy rice is one of main cereal crops of China, is extensively planted in most laboratories.The paddy of new results is not easily stored because of moisture higher (25% ~ 30%), and quality deterioration is very fast.According to statistics, China because of can not the dry in time and paddy about 2,500,000 tons that loses, be equivalent to the year consumption figure of 1,000 ten thousand people every year.Meanwhile, the energy consumption being applied to rice drying accounts for 64% of paddy production and processing total energy consumption, belongs to high energy consumption unit operations.Constantly reduce at cultivated area, grain security and energy crisis more aobvious outstanding today, after rice harvest in time, high-quality, low energy consumption drying become the important research topic in grain drying field.
The biological property of paddy self determines its heat sensitive material belonging to more difficult drying.At present, the drying mode of paddy mainly contains nature and dries and mechanical drying.By the restriction of economic condition, the mode that the many employings of most peasant households of China are dried naturally carries out drying to self-produced paddy.This drying mode is often subject to the impact of the factor such as weather and biology.Particularly south China area, results paddy runs into rainy weather often, and fresh paddy, because can not get timely drying easily mouldy or germination, causes foodstuff waste.Naturally mode of drying has been not suitable with the requirement of the market demand and the raising of plantation economy benefit.Mechanical drying, as cross-flow type drying machine, Mixed-fluid dryer and cocurrent drier etc., now many employing heated-air drying modes, this drying mode production efficiency is high, drying time shortens, decrease biological pollution (relative to naturally drying), existing be applied to extensive operation more farm and the department such as meter Ye company.But this drying mode heat utilization rate lower (< 80%), and with the discharge of heat and high humidity waste gas, energy consumption high (4.5kJ/g water).Particularly newly gather in the crops Rice Kernel Moisture Content higher, dried by hot air stream at high temperature often causes paddy that quick-fried waist occurs, and reduces drying quality.Structure all more complicated of the grain drying machine that present major part uses, expensive, and be not suitable for the drying process of a small amount of cereal.
Utility model content
The purpose of this utility model is just to provide a kind of grain drying machine to solve the problem.
In order to achieve the above object, the utility model have employed following technical scheme:
A kind of grain drying machine, comprise main cylinder, air-heater, negative pressure air scoop and agitating device, described main cylinder is the untight cylindrical shell in top, ventilative board is provided with in the bottom of described main cylinder, grain is stored in the top of described ventilative board, described agitating device is arranged on described ventilative board, and be positioned at the center of described main cylinder, described air-heater is arranged on the side of described main cylinder, the air outlet of described air-heater is connected with described main cylinder, link position is positioned at described ventilative board bottom, and described negative pressure air scoop is arranged on directly over described main cylinder.
Particularly, the side of described main cylinder is provided with charging aperture and discharging opening, and described charging aperture is arranged on the side top of described main cylinder, and described discharging opening is arranged on the side bottom of described main cylinder.
Further, described main cylinder is also provided with logical optical window.
Particularly, described agitating device comprises vertical machine and auger post, and the rotating shaft of described vertical machine is connected with described auger post.
The beneficial effects of the utility model are:
The utility model is a kind of grain drying machine, relatively simple for structure, employing is upwards led to hot blast by bottom and is carried out drying, and arrange in the upper end of main cylinder negative pressure air scoop will produce moisture derive, this drying mode effectively can prevent the mouldy of paddy or germinate, cause the waste of grain, and drying efficiency is higher, there is the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model grain drying machine.
In figure: 1-negative pressure air scoop, 2-main cylinder, 3-agitating device, 4-air-heater, 5-leads to optical window, 6-ventilative board, 7-charging aperture, 8-discharging opening.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the utility model is a kind of grain drying machine, comprise main cylinder 2, air-heater 4, negative pressure air scoop 1 and agitating device 3, main cylinder 2 is the untight cylindrical shell in top, ventilative board 6 is provided with in the bottom of main cylinder 2, grain is stored in the top of ventilative board 6, agitating device 3 is arranged on ventilative board 6, and be positioned at the center of main cylinder 2, air-heater 4 is arranged on the side of main cylinder 2, the air outlet of air-heater 4 is connected with main cylinder 2, and link position is positioned at ventilative board 6 bottom, and negative pressure air scoop 1 is arranged on directly over main cylinder 2.
The side of main cylinder 2 is provided with charging aperture 7 and discharging opening 8, and charging aperture 7 is arranged on the side top of main cylinder 2, and discharging opening 8 is arranged on the side bottom of main cylinder 2.Main cylinder 2 is also provided with logical optical window 5.
Agitating device 3 comprises vertical machine and auger post, and the rotating shaft of vertical machine is connected with auger post.
When cereal is dried, cereal enters main cylinder 2 by charging aperture 7, in main cylinder 2, ventilative board 5 only plays logical wind action, cereal is not by ventilative board 5, air-heater 4 works, and agitating device 3 works, and carries out horizontal stirring to cereal, cereal is evenly dried, and dries the negative pressure air scoop 1 of gas above main cylinder 2 produced and discharges.
