Description
Technical field
This utility model belongs to drying plant technical field, is related to aspiration circulating grain dryer.
Background technology
The grain major part contained humidity that peasant has just harvested is higher, such as reduces moisture not in time, can cause in storage, fortune
There is rotten situation of going mouldy and germinate in the links such as defeated, processing, so grain drying becomes an important step in grain puerperal,
It is an extremely important condition of grain security storage.Artificial dry in the sun, not only needs very big place, and grain is being spread
It is put into during grain is packed up storage after dry in the sun place, solarization are got well, wastes time and energy, labor intensity is larger, and work efficiency is relatively low,
So foodstuff drying device arises at the historic moment.
The foodstuff drying device industry of China starts to walk from initial extensive style, drum-type, is stepped up to criticize from after 2012
Secondary tower crop drier, increased high tower continuous dryer again from 2013, and in China, domestic grain drying device is new so far
Old altogether three generation products come into operation, and capture China's grain heat-drying market, are that the grain processing of China's agricultural production is done and contributed,
Putting on market in all different degrees of demand for having complied with market at that time of different historical stages for three sections of products, meets grain
The processing hope of Planting household.But the improvement of the adjustment and pattern of farming with national policy, three sections of products all can not meet use
Demand, gives individually below and dialyses:
(1) extensive roller dryer:
The product is that market starts, and thing, material enable such type, this machine containing purchase spot and processing stand Feedstuff Enterprises
The manufacture of type, start to be very extensive do not possess detection, control function, the direct grind turning in cylinder of grain is particularly easy to dry
Jiao, the uniformity are very low, and loss rate is very high, and the product has essentially dropped out market now.
(2) batch tower crop drier:
The product is the foreign technology introduced, and the introduction of the technology is primarily directed to China's Rice Production and manufactures and designs
Product, the listing of the product are made that certain contribution for Rice Production industry, but the product cost is high, it is high to consume energy, work effect
Rate is low, and the corn brightness of drying is low, and the rice quality of baking is poor, but peasant does not have advanced technical equipment select this to set yet
It is standby to be processed production.
(3) continuous type drying tower foodstuff drying device:
This type is to enter market in recent years, the major consumers market of the product be for high-volume grain processing family,
Particularly sold in northeast, Inner Mongol, three, Xinjiang area, the farm big farming household in above-mentioned area, home farm is relatively
Many, the temperature of the product drying is higher, and grain is mainly Semen Maydiss, and other products can not be dried, and the advantage of the product is that baking amount is big,
Yield is high, but drying expense is also high, and its minimum temperature is 180 DEG C, and above drying yield is mainly dried by high temperature, the product
Maximum problem is:1. the Semen Maydiss form gelatinizing dried, the product for baking can only be made feedstuff and can not eat, and go out starch rate also very
It is low;2. cost is high, dries costly;3. put into high;4. the use range and the range of work of the product is limited.
Three sections of products more than comprehensive, no matter advantage might as well, shortcoming might as well, be all that using single, range of application is limited, and all
Using the drying processing for having medium, the increase of production cost is caused, because there is medium increase to cause drying expense to increase, this is put into
Impute to the user of drying plant.

Collision many times, loss rate are higher, and the utility model realizes the direct heat exchange of hot blast and grain, and grain is not any
The collision of amboceptor, only hot blast and grain combine together, and hot blast will not make grain damaged, so drying course loss rate is almost
Zero.
F, because without parameters such as medium, temperature, wind speed, efficiency, grain flows, can be according to the granular size of grain, weight
Amount, adaptive temperature, gelatinization degree, receipts bud rate, percent cracked rice, flour extraction etc. are adjusted correspondingly, so as to according to drying grain product
The difference planted performs different stoving processes, and this utility model realizes heat exchange, hot blast using the hot blast and grain of different temperatures
Will not recycle, all be new warm-air supply grain that thermal source is sent, there is no the moisture regain that return air brings, only grain moisture content and tide
Wet discharge realizes dehydration, makes grain quality not get damp again the pollution for bringing, either Oryza sativa L., seed, millet, Semen Maydiss, various beans
Class, during drying and dewatering discharges some nuisances of grain so that the quality of grain keeps genuine, improves grain
Quality.
(2) air draught type drying is with advantages below:
A, with high-power air suction function grain with inhale per hour grain 20-25 tons circulation rate lifted, a few minutes when
Between complete once to be lifted, the purpose of dehydration is realized in the heat exchanging process of a few minutes, drying time is shortened, baking is improve
Dry efficiency;
