Microwave insecticidal equipment is mainly used for drying and insecticidal effects on various types of herbal teas, health drinks, traditional Chinese medicine decoction pieces, grains for health preservation, boards, and other items containing insects or insect eggs. The microwave insecticidal and antifungal equipment can complete the process of killing and preventing insect eggs within 3 minutes. It has the advantages of low temperature for insecticidal eggs, thorough insecticidal effects, and easy operation.
Classification of microwave insecticidal equipment
Microwave insecticidal and antifungal equipment is divided into two styles: box type and assembly line equipment
Working principle of microwave insecticidal equipment
It utilizes the thermal and non thermal effects (also known as biological effects) of microwave energy to interact with insect eggs and fungi, both of which can affect physiological changes and responses in organisms. The thermal effect of microwaves on living organisms is that the organisms absorb microwave energy and convert it into thermal energy (heat) inside the body, causing their own temperature to rise. This leads to the phenomenon of thermal denaturation and coagulation (>5a}) of the proteins that make up the organism, thereby rapidly killing insect eggs and bacteria.
Application of Microwave Insecticide and Mold Prevention:
1. Insecticide: A Japanese company successfully treated a grass mat with microwave insecticide. When the temperature of the grass mat rises to around 60 ℃, the pests and eggs inside have been killed. The practice of some manufacturers in Huangyan, Zhejiang has also proven that using microwaves for insecticide, sterilization, and prevention of mold has good effects. Practice has shown that when the temperature of agricultural products reaches 55 ℃ -60 ℃, their adult insects, larvae, pupae, and eggs have been completely killed.
2. Enzyme inactivation: In the processing of food and agricultural products, it is often necessary to inactivate certain enzymes. For example, flour made from mature grains has strong alpha amylase activity and must be inactivated. Otherwise, the interior of the bread will become tough, which can also be problematic when used in other areas such as adhesives, thickeners, and fillers. European countries produce wheat. Due to the particularly strong activity of its alpha starch, it is more urgent to inactivate the enzyme. The commonly used method is to heat the flour to a temperature much higher than 64 ℃, which will result in the loss of moisture in the flour and require reprocessing. But using microwaves only requires heating for a few tens of seconds to reduce enzyme activity to an acceptable level, and can also kill a large number of microorganisms in flour without affecting its main characteristics.
Microwave insecticidal and enzyme killing equipment is widely used in the treatment of grains, miscellaneous grains, herbal products, Chinese medicinal materials, wood products, bamboo products and other products. Compared with chemical insecticides, diatomaceous earth insecticides, neutron radiation insecticides, and Y-ray radiation insecticides, microwave insecticidal and enzyme killing equipment is simpler, easier to operate, requires less investment, has no radioactive pollution or residue, and is safer. It is also a thorough insecticidal and enzyme killing method.
