Screening and drying integrated screen for seed processing

Abstract

The invention discloses a screening and drying integrated screen for seed processing, and belongs to the technical field of seed processing. According to the screening and drying integrated screen forseed processing, seeds can be screened and dried at the same time, so that the working procedure is simplified, and the processing efficiency is improved; a special drying layer and a special water absorption layer are arranged, and water on the surfaces of the seeds is dried through a direct moisture absorption method; compared with a hot air method, the activity of the seeds cannot be affectedby high temperature; a water guide core is arranged in a matched mode and can guide the water absorbed by the drying layer into an specially-made expansion heating agent to enable the expansion heating agent to expand and heat; a water guide net rope set and a heat conduction assembly are arranged, wherein the water guide net rope set can assist the water guide core in guiding water, the heat conduction assembly can guide heat to the drying layer to accelerate the evaporation of the water in the drying layer, and therefore drying efficiency and effect is improved; and through arrangement of aninertia pressure assembly and the like, the drying effect can be further improved while the seeds are effectively screened.

Description

technical field [0001] The invention relates to the technical field of seed processing, in particular to a screening and drying integrated screen for seed processing. Background technique [0002] Seeds refer to the specific propagules of gymnosperms and angiosperms, which are formed by pollination and fertilization of ovules. Seeds are generally composed of three parts: seed coat, embryo and endosperm. Some mature seeds of plants only have two parts: seed coat and embryo. Seed formation enables young sporophytic ovules to be protected by the mother and nourished like a mammalian fetus. Seeds also have various structures suitable for spreading or resisting unfavorable conditions, creating favorable conditions for the continuation of the plant race. Therefore, in the process of plant phylogeny, seed plants can replace ferns to obtain the dominant position. [0003] In order to prevent the seeds from becoming mildewed during storage, the seeds need to be disinfected and cle...

AI Technical Summary

Problems solved by technology

[0003] In order to prevent the seeds from becoming mildewed during storage, the seeds need to be disinfected and cleaned before storage, and the seeds must be screened to remove unqualified seeds. After disinfection and cleaning, there will be residual water on the surface of the seeds, and now The sieve of the seed screening machine in the prior art generally only has a screening function. Therefore, the seeds need to be dried separately before screening, and the process is cumbersome, which reduces the processing efficiency. In the prior art, for the screening of seeds , usually using hot air drying, during the drying process, the temperature is higher, which is easy to reduce the activity of the seeds
