Herbal tea is deeply loved by the public for its natural taste, fresh aroma, and healthy drinking experience. But in the processing of herbal tea, drying and insect egg treatment are key links to ensure product quality and food safety. The traditional method of drying and killing insects often has many drawbacks, while the microwave secondary drying and insect killing technology, with its unique advantages, has become a high-quality processing method in the current processing of herbal tea. It can quickly complete the processing while protecting the quality of herbal tea as much as possible.
After picking and initial processing, it is difficult to completely solve the problems of uneven moisture content and residual insect eggs in herbal tea, even after a basic drying process. The folds of flower petals, gaps in sepals, and the interior of flower stamens can easily hide insect eggs. The heat generated by traditional drying methods is difficult to penetrate these areas and cannot completely inactivate the insect eggs; At the same time, the residual moisture inside the material can also cause moisture regain and mold growth in herbal tea during storage, affecting the shelf life of the product. The microwave secondary drying technology for killing insect eggs is an effective solution to these problems.
The core of microwave secondary drying insecticidal eggs is to use the characteristics of microwaves to complete the treatment. Microwaves belong to electromagnetic waves that can directly penetrate the tissue structure of herbal tea, causing water molecules inside the material and polar molecules inside the insect eggs to vibrate rapidly and high-frequency, generating heat through intermolecular friction. This heating method is completely different from traditional hot air heating. It does not slowly transfer heat from the surface of the material to the inside, but achieves synchronous heating inside and outside. The heat can directly reach the fine parts of the herbal tea, making the drying and insecticidal eggs uniform and thorough.
The prominent advantages of this process are short processing time and fast speed. Microwave technology can complete secondary drying and insect egg inactivation in just a few minutes. Greatly shortening the processing time of herbal tea, improving overall processing efficiency, and reducing the residence time of herbal tea in the processing stage, it can lock in the natural color of herbal tea to the maximum extent, keeping the petals and leaves in a bright and natural state, while retaining its fresh and unique aroma, allowing herbal tea to restore its original flavor as much as possible after brewing, reducing the risk of quality damage.
