Abstract
The utility model discloses a grain drying device, which comprises a preheating cabin, a drying chamber and an electric heating hot air generating chamber that are arranged from top to bottom. The grain drying device is characterized in that the top of the preheating cabin is provided with a feeding hole, and the lower part of the preheating cabin is provided with a material automatic-outflow port; the drying chamber is internally provided with a plurality of vertical slots provided with through holes, wherein the top of each vertical slot is communicated with the material automatic-outflow hole of the preheating cabin, and the bottom of each vertical slot is communicated with the electric heating hot air generating chamber at the lower side; and an electric heating plate is arranged in the electric heating hot air generating chamber, and a negative pressure fan is arranged outside the electric heating hot air generating chamber. The grain drying device disclosed by the utility model is free of environment pollution, good in drying quality and stable in performance and effectively reduces the probability of skin cracking or internal cracking of grains in the drying process.
Description
Technical field
The utility model relates to grain drying device, particularly a kind of foodstuffs electric drying apparatus.
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 that increases income more needs safety stock.The key of the safe storage of grain is to reduce the moisture in the grain, the generation of going mouldy with minimizing.At present, some grain depots of China and grain processing plant change to the drying mechanization technology mode from the conventional method that artificial airing reduces moisture the grain.The outstanding advantages of drying mechanization technology mode is the restriction that can not be subjected to natural conditions, but all weather operations, and oven dry is large in batches, high efficiency, but, the confession hot charge of the drying plant that adopts now mainly is coal, diesel oil, kerosene etc., ubiquity pollution problem in the drying course, and steep temperature rise in the drying course, can make rapidly drying shrinkage of grain skin, produce larger peripheral 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 the 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 utility model has carried out brand-new design to the dryer in the existing grain drying device, the technical solution of the utility model is: a kind of grain drying device, comprise that the pre-heating cabin, hothouse, the electro-thermal that arrange become humorously the chamber from top to bottom, it is characterized in that, the pre-heating cabin top is provided with charging aperture, and the bottom is provided with material from flow export; Be provided with some vertical slots with through hole in the hothouse, the top of vertical slot communicates from flow export with the material of pre-heating cabin, and the bottom becomes humorously the chamber to communicate with the electro-thermal of below; Electro-thermal becomes humorously the indoor electric hot plate that is provided with, and electro-thermal becomes humorously the outdoor negative-pressure air fan that is provided with.
Further, the sidewall of described pre-heating cabin and hothouse is provided with a plurality of oolemmas as peep hole, can dry in the air by a plurality of peep holes in the whole touring drying course and hope the oven dry process of in time adjusting.
The beneficial effects of the utility model;
(1) the utility model has thoroughly solved existing dryer take coal, diesel oil, kerosene etc. as for hot charge produced pollution problem with the supplying heat source of electric heating as drying plant, belongs to the environment-friendly type grain drying device.
(2) the designed vertical slot formula web plate hothouse of the utility model makes grain and hot warm braw comprehensive engagement carry out heat exchange, oven dry quality better, stable performance; And can go the rounds to work continuously high efficiency.
(3) the utility model to grain preheating, effectively reduces the situation of grain skin crack in the drying course (frightened line) or internal cleavage (quick-fried waist) by pre-heating cabin, has improved the commodity value of grain after the baking, has guaranteed the financial benefit of enterprise.
(4) the utility model is simple in structure, but the little long-term gain of one-time investment tally with the national condition, be particularly suitable for grain depot, farm, seed production, rice factory, flour mill, feed factory and brewery and promote the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Wherein: pre-heating cabin-1, hothouse-2, electro-thermal become humorously chamber-3, charging aperture-4, material from flow export-5, vertical slot-6, electric hot plate-7, negative-pressure air fan-8, peep hole-9.
The specific embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of grain drying device comprises that the pre-heating cabin 1, hothouse 2, the electro-thermal that arrange become humorously chamber 3 from top to bottom, it is characterized in that, pre-heating cabin 1 top is provided with charging aperture 4, and the bottom is provided with material from flow export 5; Be provided with some vertical slots 6 with through hole in the hothouse 2, the top of vertical slot 6 communicates from flow export 5 with the material of pre-heating cabin, and the bottom becomes humorously chamber 3 to communicate with the electro-thermal of below; Electro-thermal becomes humorously to be provided with electric hot plate 7 in the chamber 3, and electro-thermal becomes humorously chamber 3 to be outside equipped with negative-pressure air fan 8.
Further, the sidewall of described pre-heating cabin 1 and hothouse 2 is provided with a plurality of oolemmas as peep hole 9, can dry in the air by a plurality of peep holes 9 in the whole touring drying course and hope the oven dry process of in time adjusting.
Grain to be dried by the fire is promoted by elevator and enters dryer feeding mouth 4, electro-thermal becomes humorously the electric hot plate 7 in the chamber 3 to open, grain is carried out preheating, after pre-heating cabin 1 is filled, level detector control (not shown) control material is opened from flow export 5 by buying securities with all one's capital, material flows into hothouse 2, hot blast carries out damp and hot exchange to the grain that enters between the vertical slot 6 from pre-heating cabin 1, in this process, grain is top-down flowing always, and hot blast moves from bottom to top, and negative-pressure air fan 8 suctions mix the purpose that wind reaches oven dry, can be by the prestige of drying in the air of a plurality of peep holes 9 in the whole touring drying course, guarantee that the oven dry operation carries out situation smoothly.
Claims (2)
1. a grain drying device comprises that the pre-heating cabin, hothouse, the electro-thermal that arrange become humorously the chamber from top to bottom, it is characterized in that, the pre-heating cabin top is provided with charging aperture, and the bottom is provided with material from flow export; Be provided with some vertical slots with through hole in the hothouse, the top of vertical slot communicates from flow export with the material of pre-heating cabin, and the bottom becomes humorously the chamber to communicate with the electro-thermal of below; Electro-thermal becomes humorously the indoor electric hot plate that is provided with, and electro-thermal becomes humorously the outdoor negative-pressure air fan that is provided with.
