New technology of pre-treating processing of grain crops seeds by protective-incentive means

Abstract

As the result analysis of known materials in the field of seed preparation, patent search and their systematization, an innovative approach is proposed, on the basis of which a conceptual model of a new technology for pre-sowing seeds of cereals by working solutions of chemical and biological protective-stimulating agents with preliminary dust cleaning in a continuous hermetic single technological flow. According to the proposed technology pre-sowing preparation is carried out directly at the seed storage site, which excludes energy-consuming and labor-intensive loading-unloading and transportation operations. The basis of the new technology is a combined machine for pre-sowing treatment with pneumatic loading and dust separating device, which works as follows. Seeds, from a boot by a pneumatic loader, where the seed surface is cleaned of dust, are fed into the dust separator. In the dust separator there is a separation of seeds and a dust-air mixture. In this case, the cleaned seeds without contact with the dusty medium are sent to the treatment zone where the fine particles of the working fluid (less than 40 microns), moving in the air flow, are applied to the surface of the seeds, which ensures the accuracy of the rate of application and the uniformity of the working solution distribution by the weight of the seeds and on the surface of each grain. When pre-sowing seed treatment with biopesticides, a temperature regime is maintained that ensures the vitality and effectiveness of the biopesticides action. The processed seeds are packed in sacks and sent for sowing. The proposed technology will provide increased productivity and reduced energy intensity of the technological process, reducing the seeds trauma, eliminating the over expenditure of expensive protective and stimulating agents and improving the quality of processing, high life activity and effectiveness of biopesticides exposure, reducing environmental stress and harmful effects on humans.
