Seed treatment instrument of cold plasma

Abstract

A cold plasma apparatus for treating seeds to improve the germination rate and quality of seeds has a cylindrical body with feeding inlet, discharging cutlet, cavuumizing port and air inlet, parallel upper and lower plate electrodes in said cylindrical body, a seed conveying belt driven by power unit to pass through the region between said upper and lower plate electrodes, a RF source connected electrically with said upper and lower plate electrodes, and metallic shielding cover for said plate electrodes.

Description

technical field [0001] The present invention relates to a seed treatment device, in particular to a cold plasma seed treatment apparatus. Background technique [0002] In agricultural production, seeds of various crops usually have a selection and treatment process before sowing. Seed selection and seed treatment have a direct impact on their germination, production, yield, and the nutritional content of fruits. In recent years, the technology of using plasma to treat crop seeds has been adopted. For example, a low-temperature plasma seed processor disclosed in Chinese patent CN1203752C generates a certain degree of vacuum in the cavity, and uses a radio frequency source and an induction coil to generate a glow discharge , activating the internal energy of crop seeds, so as to achieve the purpose of increasing yield and improving product quality. However, this kind of seed processor has the following shortcomings. The induction coil will generate eddy current and magnetic s...

AI Technical Summary

Problems solved by technology

However, this kind of seed processor has the following disadvantages. The use of induction coils will generate eddy currents and magnetic short circuits, resulting in a sharp increase in power consumption, resulting in waste of energy, and at the same time the processing efficiency is also greatly reduced.

There is a foreign technology that uses radio frequency source to connect two parallel electrode plates to generate glow discharge area to treat seeds, but because glow discharge will also be generated between the two electrode plates and the inner wall of the cavity, resulting in a sharp increase in power consumption and a waste of energy , and cannot produce a concentrated glow discharge area between the two plates, so the treatment efficiency for crop seeds is still very low, and no obvious effect can be achieved
