Abstract: In order to determine the best drying method and process parameters of the lotus leaf, freshly stalked lotus leaves are used as raw materials. The lotus leaves are first cleaned, graded, cut and steamed, and then steamed. Secondly, microwaves with different powers are used. Treatment to improve its drying quality; Finally, the “microwave-blast drying” process of lotus leaf tea was studied by single factor and orthogonal experiment.
After testing, it was found that steam was used. 5 min, microwave fire strength 60%, microwave drying equipment processing time is 60 s, lotus leaf tile thickness is 2. 5 cm, the blast drying temperature is 70 °C, and the blast drying time is 0. At 5 h, the obtained lotus leaf quality is better.
