Project Introduction
In recent years, countries have attached great importance to the control of the introduction of exotic pests. In particular, they may carry imported timber such as beetles and pine wood nematodes. The quarantine measures are more stringent, and quarantine treatment methods are increasingly used in wood quarantine. At present, the most popular quarantine treatment methods in the world are chemical treatment (methyl bromide) fumigation treatment and heat treatment. However, due to the strong penetrability of methyl bromide, the use of methyl bromide for wood quarantine is fast, but from an environmental point of view, quarantine and quarantine must move toward physical processing.
Compared with conventional treatment, electromagnetic wave heating such as high-frequency microwave has the advantages of uniform treatment, short time, small deformation, good quarantine effect, etc. It is a new destructive method worthy of further study. While saving processing time and reducing labor input, the problem of uneven heating is also solved.
Due to the microwave's ability to heat various electromagnetic loss media, the microwave absorption of water is particularly strong, and the general living insects have a strong ability to enrich water, especially in the larval stage of insects and in the breeding stage of nematodes. The water is much larger than its living environment. Therefore, once microwave treatment is carried out, the first to absorb energy are insects and nematodes, and the dehydration rate of living insects or nematodes is significantly higher than that of medium wood.
No Pollution
The traditional method of quarantine of wood is to adopt methyl bromide fumigation treatment. Due to its low efficiency and high pollution, especially the severe damage to the ozone layer, it has been completely banned worldwide. There is no effective quarantine and quarantine treatment to prevent and control the epidemic, resulting in restricted and blocked entry timber.
Low Loss
The MCVEY microwave wood quarantine complies with the national regulations on timber quarantine, which minimizes the loss of wood quarantine during processing. It can completely remove dangerous pests and diseases in a short period of time and completely eliminate the spread of harmful organisms.
The use of microwave radiation for processing is one of the best treatment methods in the field of wood quarantine because of its rapid, efficient and economical advantages. It not only has good economic value, but also improves the speed of port inspection and release and enhances the efficiency of “big customs clearance”. Etc., all have very important meanings, so the social benefits are also very huge.
