Pest removal system for wood packaging products

Abstract

The invention discloses a pest removal system for wooden packaging products. The system comprises a processing cabin, a high-energy microwave emitter, an infrared thermometer, an environment temperature sensor, an environment humidity sensor, a wood moisture detector, a sprayer, a central processing unit and a display module, wherein the infrared thermometer, the environment temperature sensor, the environment humidity sensor and the wood moisture detector transmit detected data to the central processing unit, and the central processing unit adjusts the working parameters of the sprayer and the high-energy microwave emitter in real time according to the received data. The method has the advantages of being environmentally friendly, short in operation time, good in pest killing effect, small in deformation after wood treatment, free of scorching and carbonization, little in pollution and the like.

Description

technical field [0001] The invention relates to the technical field of detoxification of wood products, in particular to a detoxification system for wood packaging products. Background technique [0002] According to the provisions of the International Convention for the Protection of Plant Products, the wooden packaging used for outbound goods must undergo pest removal treatment. At present, there are three main methods of wood packaging detoxification and treatment adopted in the world, including: [0003] (1) Methyl Bromide fumigation (MB for short). In this method, the wooden packaging products are first put into a closed space (usually a tarpaulin is used to cover the wooden packaging), and then methyl bromide or other chemicals are put into the tarpaulin to fumigate the wooden packaging inside the tarpaulin. , the treatment temperature is not lower than 10°C, and the treatment time is not less than 16 hours [1] . The detoxification treatment method has a good detox...

Problems solved by technology

However, because this dielectric heating treatment method needs to strictly control the wood core temperature of the wood, if the temperature is too low and the duration is too short, the effect of the pest removal treatment will not be good, and the living insects and insects remaining in the wood cannot be completely killed. Insect eggs; if the temperature is too high and the duration is too long, the inside of the wood will be browned or even carbonized and blackened [2] , can easily cause a fire and cause serious consequences
