Inner and outer double-layer seed drying box

Abstract

The invention provides an inner and outer double-layer seed drying box. The inner and outer double-layer seed drying box comprises an obliquely arranged outer layer drying box and an inner layer drying box sleeved with the outer layer drying box coaxially, wherein a partition is transversely arranged between the outer layer drying box and the inner layer drying box to divide the outer layer dryingbox into an upper drying box and a lower drying box; the top ends of the upper drying box and the lower drying box are both of an open structure and communicate with a heating fan; the side wall of the inner layer drying box is provided with a channel communicating with the upper drying box, and the channel is positioned close to the bottom end of the inner layer drying box; a lifting mechanism is arranged inside the inner layer drying box; and the side wall of the inner layer drying box is provided with a plurality of leakage holes communicating with the lower drying box, and the leakage holes are positioned close to the top end of the inner layer drying box. The oblique structure not only ensures that seeds fall to the inner layer drying box freely under the gravity, but also can reducethe falling speed, the one-time drying amount is large, the working efficiency is improved, the seeds are not damaged, and the drying effect is good.

Description

technical field [0001] The invention relates to the technical field of all-solid-state ultrafast lasers, in particular to an inner and outer double-layer seed drying box. Background technique [0002] Seeds are the reproductive system of seed plants, which play an important role in the continuation of species, but seeds cannot be sown at any time. In order to ensure that the seeds can continue to sow, grow, and reproduce in the next spring or longer, they need to be dried Or refrigerate to keep the seeds alive. However, cold storage often destroys the growth of the seeds themselves, so the method of preserving seeds is usually to dry and store. Due to the huge number of seeds and high requirements for drying effect, seed drying equipment is generally used to completely dry the seeds. [0003] At present, in the drying operation of seeds, most of the drying equipment is to wait for the seeds to be dried to be still, resulting in uneven drying and poor drying effect, so that...

AI Technical Summary

Problems solved by technology

[0003] At present, in the drying operation of seeds, most of the drying equipment is to wait for the seeds to be dried to be still, resulting in uneven drying and poor drying effect, so that part of the seeds are damaged due to excessive drying, and part of them are damaged due to drying. Insufficient drying leads to high water content, which affects the quality of the seeds, and the thermal efficiency is low
