A screening and drying integrated screen for seed processing

Abstract

The invention discloses a screening and drying integrated screen for seed processing, which belongs to the technical field of seed processing. It can not only sieve the seeds, but also dry the seeds at the same time, which simplifies the process and improves the processing efficiency. It also has a special drying layer and a water-absorbing layer to dry the moisture on the surface of the seeds by direct moisture absorption. Compared with the hot air method, the activity of the seeds will not be affected by the high temperature. It is equipped with a water guide core, which can guide the moisture absorbed by the dry layer into the special expansion heating agent, so that the expansion heating agent expands and generates heat. It is also equipped with a water-conducting mesh rope set and a heat-conducting component. The water-conducting mesh rope set can assist the water-conducting core to conduct water. The heat-conducting component can conduct heat to the drying layer, accelerate the evaporation of water in the drying layer, and thus improve the drying efficiency. And the effect, and through the setting of inertial pressure components, etc., while effectively screening the seeds, the drying effect can be further improved.

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.

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
