Description
Technical field
This utility model relates to a kind of foodstuff drying device, belongs to agricultural and dries mechanical field.
Background technology
China is large agricultural country, and agricultural machinery is produced and supports with application big country by country.Grain purchases, store, the enterprise such as processing and agricultural cooperatives, home farm use crop dryer the most in a large number, and more and more higher to the quality requirements of crop dryer machinery.Traditional foodstuff drying device drying efficiency, dry after the collection etc. of grain the most perfect, grain is short with the time of contact of hot-air, is dried thorough, needs repeatedly to be dried, increase the working strength of peasant, is unfavorable for popularizing of agricultural equipment.China is grain-production state and the country of consumption of whole world maximum, according to statistics, annual because of climate reasons, grain has little time to dry or not up to safe moisture storage standard and causing is gone mouldy, the grain that germinates is up to about 5%, if the 60709.9 ten thousand tons of calculating of national total output of grains in 2014 announced by State Statistics Bureau, be equivalent to lose more than 3,000 ten thousand ton-grain foods every year.At present, the method for grain heat-drying usually relies on thermal source, and the grain needed is shed under the effect of gravity or machinery, allows moisture slowly distribute under the effect of conduction, convection current and radiation, thus reaches the purpose of grain heat-drying；But, its furnace drying method is more complicated, equipment power consumption is high, automatization level is low, investment is big.
Existing roller dryer is mainly made up of air stove, Drying, blower fan, conveying equipment etc., its simple in construction, easy to maintenance, cost is relatively low, but owing to equipment is single, drying effect is poor, the drying effect of grain relatively large to humidity especially is undesirable, and yield is relatively low；There is presently no high-efficient simple, the drying machinery of energy-conserving and environment-protective and furnace drying method that applicable farm machine test, big farming household and village's group use.
Summary of the invention
The purpose of this utility model is: for the problem of above-mentioned existence, a kind of foodstuff drying device is provided, save the labour force of peasant, improve agricultural production efficiency, its simple in construction, easy to use, maintenance and easy maintenance, drying amount is big, grain commodity performance after drying is good, and percent cracked rice and percentage of damage are substantially reduced.
The technical solution adopted in the utility model is as follows:
The utility model discloses a kind of foodstuff drying device, including by casing and air heater, air heater is connected at the air inlet at casing top by pipeline, is provided with the drying pipe of Pear-Shaped in casing, and this drying pipe upper end connection air inlet, lower end extend to the bottom of casing；It is provided with some through holes drying on pipe, the lateral wall drying pipe or medial wall are provided with the first filter；It is provided with air outlet in the bottom of casing, at air outlet, is provided with the second filter.
Further, the top of described casing is provided with aerator, and the air inlet of this aerator is connected with air heater, and air outlet is connected with the air inlet of casing.
Further, the outlet blast of described aerator is 50-60kpa.
Further, in described casing, it is provided with the drying pipe of two or more Pear-Shaped, is connected on the air inlet of casing after the drying pipe top parallel connection of two or more Pear-Shaped.
Further, the drying pipe of described Pear-Shaped including multiple annular protrusion, the quantity of its annular protrusion is 4-6, and the distance between adjacent two annular protrusions is 20-30cm.
Further, described casing includes internal box and outer case, is provided with discharge chamber between its internal box and outer case；Internal box is provided with some through holes for connecting the interior outside of internal box.
Further, being provided with dividing plate in described discharge chamber, discharge chamber is divided into multilamellar by dividing plate.
Further, corresponding with each layer of discharge chamber outer case is respectively arranged with air vent.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, this device uses the upper mode ventilating lower air draft to dry, the speed of the efficiency of drying can be increased, ensure that the uniformity of grain heat-drying simultaneously, the grain dried by this device has the more long storage phase, can not only ensure that grain is the most effectively dried, additionally it is possible to alleviate the work load of peasant；In suspended state, making the moisture within grain fully spread, the grain quality after drying is higher, greatly reduces percent cracked rice and percentage of damage.
2, outer double-layer structure in casing uses, the mechanism of its internal box ensure that casing discharges dampness to surrounding uniformly, the discharge making moisture is more uniform, it is reasonable in design, easy to use, make grain when drying, the humid air with moisture can discharge to surrounding uniformly, making the moisture within grain fully spread, the grain quality after drying is higher；Its discharge chamber also has the function of insulation, is greatly shortened drying time, makes drying effect more preferable, and grain heat-drying yield strengthens；The structure of the upper, middle and lower of discharge chamber three layers ensure that, separates three layers, then by with the coordinating of the electromagnetic valve being located at each layer, and then ensure the upper, middle and lower three layers of casing grain be dried uniform, lift grain dry mass.
3, drying pipe is extend in casing by this device, the through hole dried on pipe is utilized to flow from inside to outside drying gas, it has more preferable air circulation and higher drying effect, avoid the situation that the grain heat-drying at middle part is uneven, in addition, the filter screen being arranged on through hole ensure that preventing grain from entering dries pipe, and affects the efficiency of drying.
