Producing technology for processing raw material seeds by corn seeds

Abstract

The invention relates to the technical field of seed processing, and in particular relates to a producing technology for processing raw material seeds by corn seeds. The producing technology comprises the processes of mechanically peeling, manually selecting ears, drying the ears, threshing and primarily clearing, and temporarily storing grains. The corn ears are subjected to temperature-varying drying by a hot air drying technology. The drying step comprises the following substeps: blowing air into an ear drying room through a lower air flue, performing the hot air drying for 12 hours at the temperature of 30-35 DEG C, performing the hot air drying for 12 hours at the temperature of 35-40 DEG C, and performing the hot air drying for 24 hours at the temperature of 40-43 DEG C; and varying the air direction, blowing air into the ear dying room from an upper air flue, and stopping feeding hot air after continuing the hot air drying for 40 hours at the constant temperature of 42 DEG C or 43 DEG C, thus completing the ear drying after the corn ears are naturally cooled. The producing technology adopts the temperature-varying drying technology to efficiently and safely dehydrate the corn ears based on the drying and dehydration property of the corn ears, improves the production efficiency and ensures the quality of raw material seeds. The producing technology can be widely applied to production of the corn seeds.

Description

technical field [0001] The invention relates to the technical field of seed processing, in particular to a seed production process for corn seed processing raw materials. Background technique [0002] Seed processing can improve seed quality and obtain commercial seeds with high purity, high germination rate, high purity and high vitality. It is a basic technical measure to improve the commercialization of seeds and promote the circulation of seeds in the market. Seed processing includes pretreatment, basic cleaning, selection and grading, coating pelletization, weighing and packaging, etc., covering the processing process from harvesting, threshing to pre-sowing. Raw material seeds for corn seed processing refer to corn kernels obtained after harvesting of corn ears after peeling, drying, threshing, etc., which have relatively consistent material characteristics and can be directly used for subsequent operations such as cleaning, selection, and storage. Raw seed production...

AI Technical Summary

Problems solved by technology

The following problems usually exist in the production process of existing raw material seeds: manual peeling operation is labor-intensive and low in efficiency, mechanical peeling operation cost is high, and the damage rate is high; natural drying of corn ears is easily affected by the weather and the drying time is long and labor-intensive Large, low labor efficiency, unstable seed quality, large investment in ear drying facilities, high technical requirements for drying control

On the whole, the production process of raw material seeds has many links, diverse processes, and difficult process control. Raw material seeds are prone to problems such as reduced vitality, increased damage, unstable quality, and poor quality consistency.
