Description
Technical field
This utility model belongs to grain drying equipment field, is specifically related to the device of a kind of microwave fluid bed drying grain.
Background technology
Grain heat-drying is the very important process procedure of grain storage and following process.The particularly material such as Semen Maydis, Oryza glutinosa, receives
When obtaining, moisture is high, has seed big, has hard shell or epidermis, is difficult to quickly remove moisture removal.When heating-up temperature is low, dry
Dry material speed is slow；During temperature height, material epidermis can be caused by spalling, there is crackle in surface, and percent cracked rice increases, and makes time serious
Become material Jiao burnt, it is also possible to cause fire.
Present furnace drying method is a lot, but without can solve the problem that the problems referred to above, is still Grain Trade urgent problem.
One class exsiccator of existing use hot blast is the most tower, box, drum-type, fluidized bed dryer etc. have distinct disadvantage, gas
Temperature during body emptying is higher, and the thermal efficiency is relatively low, and energy expenditure is higher.
Newer technology is to use low temperature drying process at a slow speed, although percent cracked rice is low, quality better, but the volume of drying machine is big,
Efficiency is low, and dry rate is slow, and energy consumption is high.
Also having now utilizes microwave to be dried grain, but the dried grain of present equipment is also with higher temperature,
Should not preserve, and the waste energy, additionally the grain skewness in hothouse, causes drying effect undesirable.
Utility model content
The purpose of this utility model is to provide the device of a kind of microwave fluid bed drying grain, solves the problems referred to above.
The device of this utility model microwave fluid bed drying grain, including hothouse, hothouse one upper lateral part be provided with charging aperture,

There is feeder, below described hothouse, be provided with dividing plate with holes downward-sloping from charging aperture to discharging opening, arrange below dividing plate
There are microwave generator, dividing plate to be fixedly arranged above transverse slat, are fixed with below transverse slat no less than 2 distribution grids being vertically arranged, distribution
Having gap below plate and between dividing plate, hothouse is provided above gas outlet, and gas outlet connects cyclone separator by escape pipe,
Connect discharge nozzle below cyclone separator, top connects preheating chamber by gas backstreaming pipe, and the discharge nozzle other end connects Heat Room,
Being provided with spiral coil in Heat Room, spiral coil one end connects discharge nozzle, the other end is connected with the rewinding pipe stretching out Heat Room,
The outer cover of spiral coil is connected to heat exchanger tube, and heat exchanger tube upper end connects aerator, lower end connects preheating chamber by waste heat recovery pipe.
Gap between described distribution grid and dividing plate is from left to right sequentially reduced so that grain distribution is more uniform, and drying effect is more
Good.
Described preheating chamber is internally provided with staggered baffle plate, and baffle plate is porous plate so that pre-heat effect is more preferable.
Described dividing plate by not absorbing microwave, heat-resisting quartz glass is made.
Compared with prior art, the utility model has the advantage of:
This device is by hot and humid gas heating preliminary to material and is dried to prevent the epidermis spalling of material or quick-fried waist, and at hothouse
Inside being provided with distribution grid, it is ensured that grain is evenly distributed, drying effect is more preferable, and dried grain is carried out pre-pick up the heat
Room, prevents energy waste.
