Description

A fast drying device for a drying machine

Technical Field

The utility model relates to the technical field of drying machines, in particular to a rapid drying device of a drying machine.

Background Art

In some rural areas or towns, people will take the wheat they grow to processing stores to grind it into flour. However, since the wheat is very moist, it needs to be quickly dried in a dryer before it can be ground into flour. Therefore, a dryer that can dry wheat quickly is needed.

A current fast dryer, as described in the patent with publication number CN219776262U, comprises: a mounting support portion; an air guide device is mounted on the mounting support portion; a diversion conveying member is mounted inside the mounting support portion; a drying member is fixedly connected inside the mounting support portion; a load-bearing guide member is fixedly connected inside the mounting support portion; the mounting support portion comprises: a mounting support box, a collection box and a positioning shaft, and the collection box is slidably connected inside the mounting support box.

With respect to the above-mentioned related technologies, the applicant believes that when the rapid dryer is working, wheat is poured into the support part, transported by an inclined conveyor belt, and dried by blowing hot air from the drying element below. In actual use, the wheat at the bottom is transported by a conveyor belt for transportation and drying, and then returned to the support part for repeated drying. However, since the bottom end of the conveyor belt cannot be close to the bottom, the probability of the wheat at the bottom being transported up is small, resulting in uneven drying of the wheat, thereby affecting the quality of some ground flour.

By adopting the above technical solution, the guide plate is arranged below the conveyor belt, which facilitates the wheat to slide onto the lower conveyor belt for drying, thereby realizing multi-stage drying in the drying box and improving the drying effect.

Preferably, the first roller, the second roller and the third roller are arranged crosswise, and hot air holes are provided on the inner wall of the drying box corresponding to each conveyor belt.

By adopting the above technical solution, by opening the hot air holes on one side of the conveyor belt, the hot air blown in will be concentrated on the wheat blowing towards the conveyor belt, thereby improving the drying efficiency of the drying component.

Preferably, the gap from the bottom of the funnel to the top conveyor belt is five centimeters, and the bottom width of the funnel is smaller than the width of the conveyor belt.

After the wheat is conveyed on the upper conveyor belt, it will slide to the lower conveyor belt in sequence for drying. When entering different conveyor belts, the wheat will be turned over for drying, so as to achieve the purpose of multi-stage uniform drying of wheat in the drying box, thereby improving the quality of flour ground from the wheat after drying;

(2) By installing the drying component on the outside of the drying box and blowing hot air into the drying box through a single hot air pipe and a single hot air hole, the hot air will be concentrated and blown onto the wheat on the corresponding conveyor belt, and then discharged through the air outlet plate to form a circulation channel, so that the wheat can be exposed to the concentrated flowing hot air, thereby improving the drying effect and increasing the utilization rate of the heat generated by the drying component.
