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, perhaps microwave drying, and there is following shortcoming in drying means: the time is long, and the baking temperature height causes energy consumption too high; It is too high that while part medicine can local temperature occur, causes the plant stem-leaf surface phenomenon dry and cracked, that burn to occur.
Summary of the invention
The objective 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, weak point consuming time, and baking temperature is low, the phenomenon that can avoid the plant stem-leaf surface to burn.
To achieve these goals, the present invention adopts following technical scheme:
A kind of drying means of plant stem-leaf uses the microwave fluid unit that the plant stem-leaf wet feed is carried out drying.
In above-mentioned drying means, described microwave fluid unit is that the patent No. is 201220174418.0, and name is called the microwave fluid unit that the Chinese utility model patent of " a kind of microwave fluid unit for the solid particle drying " is put down in writing.
In above-mentioned drying means, baking temperature is controlled at 50-90 ℃, and wind speed is 0-30m/s.
In above-mentioned drying means, when adopting the microwave fluid unit to carry out drying, also be used in combination hot blast or microwave and carry 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: in the drying of the present invention with microwave fluid unit introduced plant cauline leaf, too high, the consuming time length of local temperature when having solved the dried plant cauline leaf, uneven drying is even to cause that plant stem-leaf part zoom, uneven drying are even, degradation problem under the color and luster.Characteristics such as product environment temperature of living in was low when the present invention had drying, and is little to the sample surfaces appearance effects, and energy consumption is low, and technology is simple, and is easy to operate.
The specific embodiment
Be dry object with tealeaves, change microwave power, wind speed, quality of material, the control cavity temperature is lower than 80 ℃ and investigates the microwave fluid bed to the influence of rate of drying.
With the plant stem-leaf wet feed, putting into the patent No. is 201220174418.0, and name is called the microwave fluid unit that the Chinese utility model patent of " a kind of microwave fluid unit for the solid particle drying " puts down in writing and carries out drying.The 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.
