Development of a device for disinfection by IR radiation of soil mixtures in a thin layer on a conveyor

Pest and disease control in the cultivation of greenery is an integral part of obtaining a high-quality and high yield. Heat treatment is one of the best ways to combat plant diseases and pests and allows you to quickly create the necessary sterile conditions without the use of chemicals. A device for disinfection of soil mixtures in a thin layer by IR radiation on a conveyor is being developed for heat treatment. The prepared soil mixture from the feed hopper enters the conveyor belt in a thin layer. An IR emitter with adjustable power is installed above the conveyor belt. The movement of the conveyor belt should ensure heating in the soil mixture layer up to 100 ± 5 ° C. This is controlled by a temperature sensor, which sends a signal via a programmable relay to the conveyor motor and regulates its movement. The disinfection process allows to achieve high energy efficiency due to software regulation, taking into account optimal modes and control of the processing temperature.
