Description

Technical Field

[0001] The invention relates to the technical field of seed processing, in particular to a drum-type seed initiation and disinfection machine. Background Art

[0002] Seed priming and disinfection (specifically dry heat disinfection) are important technical means to enhance the value of seeds. Seed priming technology can promote seed germination, increase germination speed and uniformity, and improve seedling rate and seedling resistance. Seed dry heat disinfection can fully kill pathogens in seeds and ensure seed health. Seed priming and disinfection require seeds to be placed in a specific temperature and humidity environment, and some seeds also have requirements for light conditions. Conventional seed priming and dry heat disinfection processes are relatively independent, and require more complex regulation of conditions such as temperature, humidity, and light intensity. It takes manpower to control a single process, with small processing capacity, poor uniformity, and poor process control repeatability. It is impossible to achieve industrial application. In addition, during the commonly used static priming or dry heat disinfection process, the seeds are stacked together and cannot fully contact the environment, affecting the uniformity of seed priming and the quality of treatment. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a drum-type seed priming and disinfection machine to solve the technical problems in the prior art that the seed priming and dry heat disinfection methods have complex environmental control, small processing capacity, poor uniformity, poor repeatability, and the priming uniformity is affected by seed stacking during the priming process; and the two processes of seed priming and dry heat disinfection can be carried out continuously or independently as needed, which greatly improves the work efficiency of high-quality seed production.

[0004] In order to solve the above technical problems, the present invention provides a drum-type seed induction disinfection machine, including a frame, a drum, a driving component, a temperature control component, a humidity control component, an induced draft component and a control system.

The driving component, the temperature control component, the humidity control component and the induced draft component are all electrically connected to the control system.

[0005] After adopting the above structure, the drum-type seed priming and disinfecting machine of the present invention has the following advantages: the seeds to be processed are placed in the containing chamber, and the temperature control component and the humidity control component are controlled by the control system to generate air with the required temperature and humidity, and the air is introduced into the containing chamber through the induced draft fan, so that the seeds are in a specific environment. During the priming process, the driving component drives the drum to rotate, so that the seeds in the containing chamber can fully contact with the environment. This priming method can improve the vitality of the seeds by accurately adjusting and controlling the moisture and temperature of different seeds and regulating the uniformity of seed treatment during the seed priming process by the drum. The present invention can be applied to a variety of crops and different combinations of treatment conditions, so as to flexibly optimize the priming conditions and achieve automatic programmed control of seed enhancement, drying and other processes. There is no need to change the conditions manually, the adjustment is simple, the processing volume is large, the uniformity and repeatability are high, and the problem of affecting the priming uniformity due to seed stacking during the priming and dry heat disinfection process can be prevented.
