Description

Has the box type multi-stage drying device that gas stirs

Technical field

The utility model relates to a kind of box type multi-stage drying device, particularly a kind of box type multi-stage drying device with gas stirring.

Background technology

In the reconstituted rice process, need dry cooling to the reconstituted rice particle after the extruding cutting.Yet the reconstituted rice particle water content after the extruding cutting is higher, temperature is higher, starch component wherein is under the big condition of temperature high humility, the gelatinization effect can take place, and makes the outer surface of reconstituted rice particle have higher viscosity, this also caused between the reconstituted rice particle to be stained with sticking degree bigger.

For the oven dry of solid particle material, often adopt tower baker, cylinder baker etc., under the convection current or following current effect of hot-air, the moisture of solid particle material is taken away, thereby with its oven dry.Yet because reconstituted rice particle outer surface has viscosity higher,, will very easily be stained with the group of sticking between the reconstituted rice particle, block drying unit in case adopt baroque tower drying unit to carry out large batch of oven dry.Be stained with coherent particle simultaneously and also can bring the uneven situation of oven dry.

Because the reconstituted rice water content is higher, in drying course, as drying fast, when reaching the water content requirement, the outer surface of reconstituted rice particle produces the crackle of be full of cracks through regular meeting.This is because when adopting hot-air seasoning in the drying course, hot-air is taken away the water of particle surface rapidly, and that the water of granule interior is not easy is volatilized, thereby make particle surface different with the evaporation rate of the water of inside, when the water content of granule interior reached requirement, particle surface was but because dehydration too much produces be full of cracks.Another causes the reason of above-mentioned situation to be, the process of oven dry is fierce too rapidly, there is not time enough to be diffused into particle surface by the water of granule interior, remedy surperficial different and water content difference that bring with the internal water evaporation rate, make granule interior and the surface the water content balance, avoid surface checking.

Simultaneously in the reconstituted rice drying course, because surface and inner water content inequality, even if the particle surface after the oven dry is be full of cracks not, yet after placing a period of time, still can chap, and the situation of this water content inequality also caused boiling in the process in reconstituted rice, and the reconstituted rice particle is very easily damaged, causes nutriment that reconstituted rice adds etc. to run off along with water.

Yet existing drying unit and method can't solve that reconstituted rice is intergranular is stained with sticking situation, and it is uneven and produce the situation of be full of cracks also can't to solve the volatilization of particle surface and internal moisture.
