Plant stem and leave drying method

Abstract

The invention discloses a plant stem and leave drying method. Microwave fluidized bed equipment is used for drying wet materials of the plant stem and leave, the patent number of the microwave fluidized bed equipment is 201220174418.8, and the microwave fluidized bed equipment is recorded in China patent for utility models with the title of 'microwave fluidized bed equipment for drying solid particles'. The plant stem and leave drying method includes that drying temperature is controlled at 50-90 DEG C, and wind speed is at 0-30m / s; and hot wind or microwave are combined to be used for drying the time when the microwave fluidized bed equipment is adopted; and diameters of the wet materials of the plant leaves are 2cm-8cm, and water content is 12%-25%. With the plant stem and leave drying method, the problems of parts of the plant leaves being burnt with uneven drying and color fading caused by high local temperature, long time consumption and uneven drying when the plant leaves are dried are solved. The plant stem and leave drying method of the plant leaves has the advantages that environment temperature is low when the plant leaves are dried, surface appearance of samples are not affected much, energy consumption is low, processing is simple, and operation is facilitated and the like.

Description

[0001] technical field [0002] The invention relates to a method for drying plant stems and leaves. Background technique [0003] At present, the stems and leaves of plants in tea production plants or plant raw material processing plants are generally dried in ovens or microwaves. The drying method has the following disadvantages: long time, high drying temperature, resulting in high energy consumption; High, causing the surface of plant stems and leaves to appear cracked and scorched. Contents of the invention [0004] The purpose of the invention is to overcome the deficiencies of the prior art and provide a method for drying plant stems and leaves. The method of the invention has the advantages of simple operation, low energy consumption, short time consumption and low drying temperature, and can avoid the scorching phenomenon of the surface of plant stems and leaves. [0005] In order to achieve the above object, the present invention adopts the following techn...
