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
Technical field
The present invention relates to a kind of drying means of plant stem-leaf.
Background technology
At present, the plant stem-leaf of Tea Production factory or plant material processing factory generally adopts oven drying, or microwave drying, and drying means exists following shortcoming: the time is long, and baking temperature is high, causes energy consumption too high; Simultaneously to there will be local temperature too high for some drugs, causes plant stem-leaf surface to occur phenomenon that is dry and cracked, that burn.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of drying means of plant stem-leaf is provided.Method of the present invention is simple to operate, and energy consumption is little, and consuming time short, baking temperature is low, can avoid the phenomenon that plant stem-leaf surface is burnt.
To achieve these goals, the present invention adopts following technical scheme:
A drying means for plant stem-leaf, uses microwave fluidized-bed equipment to carry out drying to plant stem-leaf wet feed.
In above-mentioned drying means, described microwave fluidized-bed equipment is the patent No. is 201220174418.0, the microwave fluidized-bed equipment described in Chinese utility model patent that name is called " a kind of microwave fluidized-bed equipment for solid particle drying ".
In above-mentioned drying means, baking temperature controls at 50-90 DEG C, and wind speed is 0-30m/s.
In above-mentioned drying means, while microwave fluidized-bed equipment carries out drying in employing, also combinationally use hot blast or microwave carries out drying.
In above-mentioned drying means, the diameter of described plant stem-leaf wet feed is at 2cm-8cm, and water content is 12% ~ 25%.
Compared with prior art, the present invention has following beneficial effect: the present invention is by the drying of microwave fluidized-bed equipment introduced plant cauline leaf, and local temperature too high, consuming time length when solving dried plant cauline leaf, uneven drying cause degradation problem under plant stem-leaf part zoom, uneven drying, color and luster.The features such as when the present invention has a drying, residing for product, environment temperature is low, and little to sample surfaces appearance effects, energy consumption is low, and technique is simple, easy to operate.
Detailed description of the invention
With tealeaves for dry object, change microwave power, wind speed, quality of material, control cavity temperature and investigate the impact of microwave fluid bed on rate of drying lower than 80 DEG C.
By plant stem-leaf wet feed, putting into the patent No. is 201220174418.0, and the microwave fluidized-bed equipment described in Chinese utility model patent that name is called " a kind of microwave fluidized-bed equipment for solid particle drying " carries out drying.Plant stem-leaf wet feed is put into the hierarchical system of microwave fluid bed, be dried to water content <5%, plant stem-leaf is taken off from hierarchical system, obtain dried product.
