Problems solved by technology

[0003] Most of the existing lotus leaves are used in dietotherapy, and there are relatively few teas. In the paper "Research on the New Technology of Microwave-assisted Drying of Lotus Leaf Tea", the production method of lotus leaf tea is introduced. The specific steps are as follows: Fresh Wash the lotus leaves and cut them into pieces, use water steam to fix them, and then knead them. The kneaded lotus leaves are dried by microwave, and then continue to dry with hot air in an oven. The lotus leaf tea has a strong aroma, but it has the following disadvantages: Cut the lotus leaves before steaming, which will easily cause the lotus leaves to be oxidized during cutting, and the color will not look good. Although microwave drying can improve the fragrance, it is easy to overdry, the sensory quality is not good, and the rehydration is not good. , because the lotus leaf itself has a bitter taste, if the finished product needs to be soaked before drinking, the lotus leaf water will be very bitter after soaking, and many people do not like bitter tea, which will affect the sales of lotus leaf tea.
