Abstract

The invention discloses a drying method of a Chinese medicinal material. The method comprises the following steps of: (1) uniformly spreading a Chinese medicinal material in an environment control room with thickness of between 2.0 and 6.0cm; setting an ultraviolet lamp, an ozone generator, a refrigeration air conditioner and an industrial dehumidifier, controlling the environment temperature to be between 10 and 22 DEG C by the refrigeration air conditioner, controlling the environment humidity to be between 10 and 50 percent by the industrial dehumidifier, and dehumidifying and drying the Chinese medicinal material for 2 to 24 hours; and (2) transferring the Chinese medicinal material into an electrothermal draught circulating drying oven for drying at a temperature of between 50 and 70 DEG C for 2 to 12 hours. The drying method improves the product quality, is applicable to drying treatment of massive Chinese medicinal materials, as well as foods, medicaments, pollen and the like.

Description

A kind of Chinese crude drug drying means

Technical field

The invention belongs to the drying means technical field of Chinese crude drug.

Background technology

When present valuable medicinal Cordyceps, Cordyceps militaris (L.) Link. (Cordyceps militaris), golden Periostracum cicadae (also claiming large Cordyceps), all kinds of pollen drying, because the Thermo-sensitive of various effective ingredient, excess Temperature will affect and destroy effective ingredient (or nutritional labeling), so the baking temperature general control is below 60 ℃ even lower.During the oven dry carried out under 60 ℃ of conditions, because medical material and pollen humidity are too high, and temperature is fit to the growth of microorganism amount reproduction, in dry run, how can cause going mouldy of Chinese crude drug and pollen, causes finished product microbial limit severe overweight, affects quality.And relatively large with the electric energy consumption that the method is used, drying time is long, and equipment investment is large, and a large amount of oven dry need large-scale baking oven to use for a long time.

The traditional furnace drying method of the many employings of Cordyceps, Cordyceps militaris (L.) Link., golden Periostracum cicadae and the relevant solid fermentation culture products etc. of selling in the market, it is black that outward appearance obviously becomes, and there is certain influence in quality.And the baking needed energy consumption is large, and the input of the equipment such as drying plant is larger.

Summary of the invention

The objective of the invention is: the deficiency for prior art exists, provide a kind of and can guarantee the Chinese crude drug quality, and the little drying means of volume drying energy consumption.

For realizing the present invention's purpose, be achieved by the following technical solutions: a kind of Chinese crude drug drying means is characterized in that may further comprise the steps successively:

1.. Chinese crude drug is placed in the environmental control room, evenly spread out, THICKNESS CONTROL is at 2.0-6.0cm; Uviol lamp, ozonator, refrigeration air-conditioner and industrial dehumidifier are set in the environmental control room, 10-22 ℃ of Refrigeration and Air-Conditioning control ambient temperature, the industrial dehumidifier humidity 10-50% that controls environment carries out removal moisture drying 2-24h to Chinese crude drug;

2.. change Chinese crude drug in electric heating air blast cyclic drying baking oven drying, the control oven temperature is 50-70 ℃, and be 2-12h drying time.

As preferred version: it is 4.0cm that described Chinese crude drug spreads out thickness, 20 ℃ of Refrigeration and Air-Conditioning control ambient temperatures, and the industrial dehumidifier humidity 40% that controls environment is carried out removal moisture drying 20h to Chinese crude drug; The control oven temperature is 60 ℃, and be 10h drying time.

Compared with prior art, the invention has the beneficial effects as follows: owing to before use electric heating air blast cyclic drying baking oven is dried Chinese crude drug, use first industrial dehumidifier that Chinese crude drug is carried out preliminarily dried, and use refrigeration air-conditioner that ambient temperature is controlled in the low situation and effectively prevented growing in a large number, breeding of microorganism, improve product quality, be applicable to the drying and processing of a large amount of Chinese crude drugs, and this kind drying means is equally applicable to food, medicine and pollen etc.

The specific embodiment

Embodiment 1

The Cordyceps militaris of 50kg is spread out, thickness is 2.0cm, and uviol lamp, ozonator, refrigeration air-conditioner and industrial dehumidifier are set in the environmental control room, 10 ℃ of Refrigeration and Air-Conditioning control ambient temperatures, the industry dehumidifier humidity 10% that controls environment is carried out removal moisture drying 2h to Chinese crude drug; Then Cordyceps militaris is changed over to drying in the electric heating air blast cyclic drying baking oven, the control oven temperature is 50 ℃, takes out behind the oven dry 12h.

Following table is that Cordyceps militaris uses the traditional drying method and adopts the Surveillance of drying means of the present invention to contrast.

Project	The traditional drying method	Drying means of the present invention
			Outward appearance	Partially black	Do not turn black displaing yellow
Cordycepin	1.10mg/g	1.30mg/g
			Adenosine	1.20mg/g	1.58mg/g

Embodiment 2

The Cordyceps militaris (L.) Link. (artificial sporophore) of 50kg is spread out, thickness is 4.0cm, place in the environmental control room, uviol lamp, ozonator, refrigeration air-conditioner and industrial dehumidifier are set in the environmental control room, 20 ℃ of Refrigeration and Air-Conditioning control ambient temperatures, the industry dehumidifier humidity 40% that controls environment is carried out removal moisture drying 20h to Cordyceps militaris (L.) Link.; Then change in the electric heating air blast cyclic drying baking oven and dry, temperature is controlled to be 60 ℃, takes out behind the oven dry 10h.

Embodiment 3

The artificial golden Periostracum cicadae of 50kg is spread out, thickness is 6.0cm, place in the environmental control room, uviol lamp, ozonator, refrigeration air-conditioner and industrial dehumidifier are set in the environmental control room, 22 ℃ of Refrigeration and Air-Conditioning control ambient temperatures, the industry dehumidifier humidity 50% that controls environment is carried out removal moisture drying 24h to Cordyceps militaris (L.) Link.; Then change in the electric heating air blast cyclic drying baking oven and dry, temperature is controlled to be 70 ℃, takes out behind the oven dry 2h.

In addition, drying means of the present invention is equally applicable to the drying of food, medicine and pollen etc.
