Abstract
The invention relates to a drying device, and in particular relates to a grain drying device which comprises a preheating chamber, a drying chamber and an electro thermal chamber which are arranged in sequence from top to bottom, wherein the electric thermal chamber is capable of generating hot air; a feeding hole in a funnel shape is formed in the top of the preheating chamber; baffles in a closing mode are arranged inside the preheating chamber below the feeding hole; a plurality of material ejection holes with shrunk holes are arranged at the lower part of the preheating chamber; the drying chamber is internally provided with a plurality of ventilation tubes with through holes; the top parts of the ventilation tubes are communicated with the preheating chamber; the bottoms of the ventilation tubes are communicated with the electric thermal chamber below; the electric thermal chamber is internally provided with a graphite electric thermal plate. By adopting the grain drying device with the technical scheme, grains can be sufficiently preheated without crack caused by sharp temperature raising, and the quality of the grains is ensured.
Description
Technical field
The present invention relates to a kind of drying unit, be specifically related to a kind of grain drying device.
Background technology
Along with the development of modern agriculture science and technology, advanced increases in grain production technology has obtained applying in vast rural area, yet the grain increasing income more needs safety stock.The key of the safe storage of grain is to reduce the moisture in grain, to reduce the generation of going mouldy.At present, the conventional method that some grain depots of China and grain processing plant have reduced moisture grain from artificial airing changes to drying mechanization technology mode.The outstanding advantages of drying mechanization technology mode is the restriction that can not be subject to natural conditions, can all weather operations, and dry large in batches, operating efficiency is high, but, the drying plant that adopted now, due to steep temperature rise in drying course, can make grain skin drying shrinkage rapidly, produce larger periphery tension and internal compressive stress, make grain skin crack (frightened line) or internal cleavage (quick-fried waist), quality and the commodity value of grain have been reduced, thereby, restricted to a certain extent drying mechanization technology mode at many medium and small grain depots, rice factory, the units such as flour mill apply.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of to the abundant preheating of grain, avoid steep temperature rise to cause grain cracking, guarantee the grain drying device of grain quality.
In order to solve the problems of the technologies described above, the invention provides a kind of grain drying device, comprise preheating chamber, the hothouse setting gradually and the electrothermal chamber that can generate warm braw from top to bottom, described preheating chamber top is provided with funnel-form charging aperture, preheating chamber inside below charging aperture is provided with the material baffle of reducing shape, in the bottom of preheating chamber, be provided with the material ejiction opening of a plurality of reducing shapes, in hothouse, be provided with some ventilation ducts with through hole, the top of ventilation duct communicates with preheating chamber, bottom communicates with the electrothermal chamber of below, is provided with graphite electric heating plate in electrothermal chamber.
Adopt the grain drying device tool of technique scheme to have the following advantages: grain is by funnel-form charging aperture, avoided grain to leak outside, the material baffle of the reducing shape that grain arranges by charging aperture below again, the speed that grain is fallen is cushioned, avoided grain directly to enter the impulsive force that drops to preheating chamber, simultaneously grain by material baffle after falling speed reduce, in the process that grain slowly falls, the drying and preheating that contributes to grain, the material ejiction opening of reducing shape contributes to control the speed that logistics falls, further contribute to grain to enter the abundant preheating of preheating chamber, grain falls into after preheating chamber, the graphite electric heating plate of simultaneously opening, graphite electric heating plate heats up fast, evenly, fully effectively grain is carried out to preheating, can produce the electrothermal chamber of warm braw, can so that the hot blast producing to preheating chamber, and the grain entering in hothouse from preheating chamber carries out damp and hot exchange, in this process, grain is top-down flowing always, hot blast moves from bottom to top, grain after abundant preheating is dry again, reduced the situation of grain cracking in drying course, improved the commodity value of grain after drying, guaranteed the quality of grain.
As preferred version, consider the convenience of ventilation, fast and effeciently to grain heat-drying, in described electrothermal chamber, be externally connected with centrifugal blower.
accompanying drawing explanation
Fig. 1 is the structural representation of grain drying device of the present invention;
In figure: 1-preheating chamber, 2-charging aperture, 3-hothouse, 4-ventilation duct, 5-graphite electric heating plate, 6-centrifugal blower, 7-material baffle, 8-material ejiction opening, 9-blast cap.
the specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, the invention provides a kind of grain drying device, comprise the preheating chamber 1 setting gradually from top to bottom, hothouse 3 and the electrothermal chamber that can generate warm braw, preheating chamber 1 top is provided with funnel-form charging aperture 2, preheating chamber 1 inside below charging aperture 2 is provided with the material baffle 7 of reducing shape, in the bottom of preheating chamber 1, be provided with the material ejiction opening 8 of a plurality of reducing shapes, in hothouse 3, be provided with some ventilation ducts 4 with through hole, the top that is provided with the ventilation duct 4 of blast cap 9 communicates with preheating chamber 1, the 9 pairs of interior generation exhausting of ventilation duct 4 abilities of blast cap, make ventilation duct 4 export into local decompression, be conducive to the dry of grain, ventilation duct 4 bottoms communicate with the electrothermal chamber of below, in electrothermal chamber, be provided with graphite electric heating plate 5, in electrothermal chamber, be externally connected with centrifugal blower 6.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the premise without departing from the principles of the invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
