Technical field
The utility model belongs to dryer technical field, particularly a kind of small-size grain drying machinery.
Background technology
The history of China plantation grain reaches several thousand, and in traditional grain harvesting, people rely on manpower by grain collecting, then by grain airing under sunlight, it is dewatered, so that the long term storage of grain.
But if after harvesting grain, due to weather reason (as rainy, cloudy etc.), grain can not get being dried timely, will go bad, germination etc., affect the preservation of grain.And, with regard to current Chinese countryside, most of young labour does manual work in city, and that stay rural area is some old men and child mostly, the extremely shortage of labour that this just causes rural area, makes existing rural laborer be not suitable with to a great extent the development of the rural area relations of production.
Therefore, need to greatly develop agricultural machinery, improve agricultural productive force.And for current Chinese countryside, the small-sized foodstuff drying device that is applicable to single household more can meet people's demand.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model and useful technique effect thereof are elaborated, but the specific embodiment of the present utility model is not limited to this.
Refer to Fig. 1 and Fig. 2, the small-size grain drying machinery that the utility model provides, comprise the inner core 3 of drive motors 1, axial flow blower 2, up/down perforation with holes, urceolus 4, base plate 5 and the support 6 of up/down perforation with holes, axial flow blower 2 is connected with the output shaft of drive motors 1, and axial flow blower 2 is fixed on support 6, one end of one end of one end of support 6, inner core 3, urceolus 4 is all fixed on base plate 5, inner core 3 is located in the periphery of support 6, urceolus 4 is located in the periphery of inner core 3, and inner core 3, urceolus 4 and base plate 5 form grain drying chamber 7.
Wherein, dryer also comprises the steel cylinder 9 of up/down perforation, and axial flow blower 2 is arranged in steel cylinder 9, and steel cylinder 9 is arranged at the upper end of support 6.The effect one of support 6 is to support steel cylinder 9, and the two is for for fixing inner core 3.
Dryer also comprises heater 8, and heater 8 is also arranged in steel cylinder 9, and heater 8 is arranged at the below of axial flow blower 2.What heater 8 adopted is electric heater, and its power is 1000W.Generally, heater 8 does not need to open, and only has temperature low or when overcast and rainy, can heater 8, and suitably improve drying medium temperature or reduce relative humidity.This be because, although use heater 8 can improve grain heat-drying speed, prevent the generation of the dewfall phenomenon that night ventilation grain that relative air humidity is high likely produces, but can greatly increase power consumption, thereby increasing operating cost, therefore, the using priciple of heater 8 is to guarantee not the least possible use or need not under the prerequisite of dewfall of grain.
Dryer also comprises Polypropylence Sheet 10, and Polypropylence Sheet 10 is covered on the top of grain drying chamber 7 hermetically.Polypropylence Sheet 10 is tightened with inner core 3 and urceolus 4 respectively, guarantees air tightly, improves drying effect, also prevents that grain is blown from the upper end of grain drying chamber 7.
The thickness of Polypropylence Sheet 10 is 1 μ m～10mm.The thickness of Polypropylence Sheet 10 can not be too little, otherwise easily by grain, punctured, and the thickness of Polypropylence Sheet 10 can not be too large, otherwise can increase cost.Preferably, the thickness of Polypropylence Sheet 10 is 1mm～5mm.
Inner core 3 and urceolus 4 are all set to the tubular structure of the up/down perforation that surrounded by bamboo mat, the diameter of urceolus 4 is greater than the diameter of inner core 3, bamboo mat has advantages of that intensity is large, good permeability, windage are little, do not leak grain, and can gather materials on the spot, low price, can roll collection in the time of no easily.Tubular structure can guarantee that air is along all directions distributed uniform, and then guarantees that precipitation that grain piles up each section in drying course is without significant difference, and it is basic identical that moisture remains.
Support 6 comprise rigidity foundation ring 61, rigidity collar 62 and be arranged at rigidity foundation ring 61 and rigidity collar 62 between some rigid supporting rod 63, the two ends of some rigid supporting rod 63 are welded to connect with rigidity foundation ring 61 and rigidity collar 62 respectively.
Whole dryer is when work, and under 400Pa static pressure, axial flow blower 2 can provide 1080m
3the air quantity of/h.
During use, first grain is poured in grain drying chamber 7, then with Polypropylence Sheet 10, covered the upper end (openend) of grain drying chamber 7, and tighten with inner core 3 and urceolus 4 respectively, air tight to guarantee.Then open drive motors 1, make it drive axial flow blower 2 to rotate, start to dry operation.
Drying medium is under the pressure-acting of axial flow blower 2, upper end by steel cylinder 9 enters into inner core 3, then by inner core 3, is entered in the grain heap being positioned in grain drying chamber 7, radially through whole grain heap layer, carry out heat, matter exchange with grain, reach the object that reduces grain moisture content.Owing to using normal temperature air or micro-hot-air that adds, do drying medium, the temperature of drying medium is low, relative humidity is high, the difference of steam partial pressure and grain grain surface water vapor pressure is much smaller than conventional convection current high temperature foodstuff drying device, therefore rate of drying is slow, can well guarantee grain quality, particularly suitable for being dried of paddy, can effectively prevent that cracked kernel from occurring, thereby guarantee the quality after grain heat-drying.And because rate of drying is slow, the uniform drying of inside and outside grain layer is fine.
Practice shows, while adopting the utility model, in the harvest season in rainy season, paddy is dried to operation, through the continuous drying operation of 60-100h, the moisture of 1 ton of Paddy With High Moisture Content Stored can be down to 14% left and right from 25%, and precipitation ability is about 1.8kg/h.And the rice quality after drying is good, with daylight airing and shady dry comparing, head rice rate on average improves 2%.
The announcement of book and guidance according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.In addition,, although used some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
