Description

Technical Field

[0001] The utility model relates to the technical field of seed treatment, in particular to a drum-type seed initiation disinfection device. Background Art

[0002] Seed priming and disinfection (specifically dry heat disinfection) are important techniques for enhancing seed value. Seed priming enhances seed viability by controlling the intensity and rate of water absorption by seeds, allowing the repair and activation of macromolecules, cell membranes, and organelles within the dry seed that contribute to germination activity. After priming and re-drying, seeds are in a metabolic state ready for germination. However, because radicle extension is inhibited, the seeds maintain their high viability and storage state after re-drying. Seed priming promotes germination, increases germination speed and uniformity, and improves seedling survival and seedling resistance. As a simple, effective, and easy-to-use method, seed priming is gaining increasing attention in agricultural production. Dry heat disinfection effectively eliminates pathogens and ensures seed health. Seed priming and disinfection require seeds to be placed under specific temperature and humidity conditions, and some seeds also have specific lighting requirements. Conventional seed priming and dry heat disinfection processes are relatively independent, requiring complex regulation of conditions such as temperature, humidity, and light intensity. It takes a lot of manpower to control a single process, resulting in small processing capacity, poor uniformity, and poor process control repeatability, making it impossible to achieve industrial application. Moreover, during the commonly used static priming or dry heat disinfection processes, the seeds are stacked together and cannot fully contact the environment, affecting the uniformity of seed priming and the quality of treatment.
