Automatic killing device for pathogenic bacteria of grain seeds

Abstract

The invention discloses an automatic killing device for pathogenic bacteria of grain seeds. The automatic killing device comprises a bearing platform, a pre-heating water tank, a high-temperature water tank, a cooling water tank and a material collection bucket, which are arranged on the bearing platform; the automatic killing device further comprises a roller type hoisting basket, a draught fan,a temperature sensor, a heating module and a control system, wherein the roller type hoisting basket can do spinning motion around the axis of the roller type hoisting basket; the draught fan has a hot air mode and a natural air mode. The automatic killing device disclosed by the invention can conveniently realize sterilization, drying, air cooling and unloading processes of the grain seeds and ishigh in integration degree; the treatment time is shortened and the sterilization efficiency of the grain seeds is improved; rapid switching of operation procedures can be realized; meanwhile, watercan be stirred and a temperature field of the water is enable to be uniform; the grain speeds placed in the water also can be continuously turned over, so that the grain seeds can be rapidly and uniformly pre-heated, heated or cooled; furthermore, the sterilized grain seeds can be dried and cooled with air in time so that storage requirements are met.

Description

technical field [0001] The invention relates to the technical field of seed sterilization equipment, in particular to an automatic killing device for grain seed pathogenic bacteria. Background technique [0002] Cereal seeds often carry various pathogenic bacteria, such as rice blast, bacterial streak, bakanae disease, rice smut and other fungal diseases. Seeds with pathogenic bacteria are one of the main causes of diseases during the growth of grains. Research institutes such as the China Rice Research Institute and Shanghai Jiaotong University have found through research that grain seeds carry pathogens on the surface or inside. During the breeding process, these bacteria The seeds of the pathogen often infect the seedlings or young plants, causing the disease to occur. Therefore, sterilizing the grain seeds before sowing is one of the essential steps in the sowing process of grain in modern agriculture. By sterilizing the grain seeds, the occurrence of diseases can be re...

Problems solved by technology

But it still has many problems: 1. When using warm water, hot water and cold water to process grain seeds, the seeds are in a relatively static state between the warm water or hot water or cold water, and the seeds are piled up in stainless steel baskets. This treatment method requires a long waiting time to exchange heat between the seeds and warm water or hot water or c
