Description

Seed selection processing method

Technical Field

The invention belongs to a seed processing technology, and mainly relates to a seed cleaning processing technique.

Background

With the continuous optimization and adjustment of grain crop planting modes and the popularization and application of precision seeding machines in China, the requirements of agricultural markets on the quality of the selected crop seeds are increased day by day, the development of the seed industry processing in China to automation, scale and refinement is promoted, and professional seed companies have achieved the operation state of packaging and selling according to grains, so that the agricultural technology requirements of farmers on precision seeding according to grains are met.

At present, seed selection processing factories used and built in China still adopt the traditional seed processing method, namely the processing steps are as follows in sequence: the method comprises the steps of firstly, winnowing and screening seeds, secondly, gravity sorting seeds, thirdly, grading seeds, fourthly, coating seeds, fifthly, drying seeds and sixthly, metering and packaging seeds. The seeds processed by the sequence of the process steps basically meet the use requirements of current users to a certain extent. However, in practice for many years, it has been found that the gravity sorting of seeds is arranged before the classification of seeds in the existing seed processing steps, i.e. the gravity sorting of seeds is performed before the classification of seeds, and then the classification of seeds is performed, so that the operation efficiency and productivity of the whole seed processing production line are affected and reduced, and the seed selection purity is still to be improved.

Disclosure of Invention

The invention aims to provide a novel seed selection processing process method aiming at the problems of the conventional seed selection processing process step sequence, and the purposes of greatly improving the capacity of seed selection processing production equipment with the same specification and improving the purity of finished seeds are achieved.

The purpose of the invention is realized as follows: the seed selection processing method comprises the following steps:

firstly, a seed winnowing and screening process: winnowing and screening the primarily cleaned seeds;

secondly, a seed grading procedure: classifying the seeds subjected to air separation and screening according to the overall dimensions of the length, the width and the thickness of the seeds;

thirdly, a seed gravity sorting process: sorting the seeds after grading according to the proportion, entering all levels of process bins for temporary storage before entering the proportion sorting process, and waiting for gravity sorting in sequence;

fourthly, seed coating: coating the seeds subjected to gravity separation;

fifthly, seed drying: drying the coated seeds;

sixthly, seed metering and packaging process: and (5) metering and packaging the dried and dried coated seeds.

The invention replaces and changes the seed gravity sorting process and the seed grading process before and after the seed grading process in the traditional and the conventional seed selection processing technique, namely the seed grading process is configured before the seed gravity sorting process, and the invention is the invention attribute of changing the element relationship in the element invention.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A seed selection processing technique comprises a seed winnowing and screening process, a seed grading process, a seed gravity sorting process, a seed coating process, a seed drying process and a seed metering and packaging process, wherein the method comprises the following steps:

fourthly, seed coating: coating the seeds subjected to gravity separation;

fifthly, seed drying: drying the coated seeds;

According to the traditional seed selection processing technology, the ungraded seeds are a mixture of seeds with different sizes and impurities with different specific gravities, the raw material of the mixture is difficult to be effectively selected by gravity selection, the selection quality and effect of gravity selection are seriously affected, the method of the invention firstly enters the seed classification procedure for the seeds after the seed selection and selection procedure, the seeds are divided into a plurality of grades according to the length, width and thickness of the seeds, the external dimensions of the seeds in the same grade are basically the same, although the impurities with different specific gravities are mixed in the seeds, the raw materials of the seeds in the same grade are very suitable for gravity selection processing treatment, therefore, the method firstly classifies the seeds, and then sorts the specific gravities, changes the inherent scheme of the traditional technology for many years, and solves the technical problems which are solved but can not be solved all the time in the technical field, the technical effect is obvious.

In multiple detections of scientific research experiments, on the premise that various devices of a seed processing production line are not changed, the production line sequenced according to the technological method can greatly improve the yield by more than 20%, and the net rate of selected seeds is greatly improved by more than 99% and exceeds the requirement of 98% of the finished product net rate in national standards.
