Abstract
The present invention, which relates to, discloses a kind of drying means of fructus lycii, and fructus lycii is placed on basin, and heating vacuumizes, dry, is cooled to room temperature, obtains dried wolfberry.Shorter using drying time used in fructus lycii medicinal material obtained by drying means of the present invention, medicinal material water content is lower, and red is presented in medicinal material appearance luster, and exterior quality is preferable.
Description
Technical field
The present invention relates to a kind of drying means of Chinese medicine, in particular to a kind of fructus lycii drying means.
Background technique
Fructus lycii nutrition abundant, high medical value and health value carry out more people by both at home and abroad more one
Understand approval, people also enjoy great popularity to fructus lycii product, plant in the ground large area such as China Ningxia, Gansu, not due to fructus lycii
Easy fresh-keeping, every fructus lycii mature period, large batch of fresh fructus lycii are badly in need of drying.Drying fructus lycii is in order to which long term storage is without destroying
Nutritional ingredient deviates from certain moisture by drying means, and the concentration of solable matter is increased to what microorganism was difficult to be utilized
Degree, it is that the moisture in medlar fresh fruit is made to mend the method that dried medium is taken out of and removed by thermal energy.Currently, being widely used
Dry-making method of dried mainly include the following types: first is that natural drying, Ningxia old area peasant's Chang Xuan spaciousness ventilation place, by picking
Fresh fruit is spread out on fruit stack, thickness about 2cm, and fruit stack branch is set up sunning, and the method is most economical, but drying time is long, effectively at
Divide loss big, meet and be easy to rainy days go mouldy, is easily polluted by dust, fly, mouse.Second is that taking, stove is dry, this is a kind of biography
The method of system usually builds stove on ground, lights a fire at stove bottom, fresh fruit is spread out in stove room and is dried, first in 40-45 DEG C of temperature
, there is part curly grain in lower drying 24-36h；36-48h is dried at a temperature of 45-50 DEG C again, shrinkage mark, body is all presented
Product is reduced significantly；Left and right for 24 hours is finally dried at a temperature of 50-55 DEG C to parch.The method is at low cost, disposable drying amount
Greatly, but temperature is not easy to control, and drying is uneven, and drying time is long, and energy consumption is high, poor product quality.
The present invention has invented a kind of new fructus lycii processing method on the basis of studying fructus lycii drying parameter, can
It is significantly shorter drying time, is improved efficiency, and Lycium barbarum polysaccharides and beet alkali content are substantially improved, the moisture content of fructus lycii
It can be controlled within 5%, provides one kind newly for the high-quality and efficient production of fructus lycii medicinal material and the development and utilization of fructus lycii child resource
Approach.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of new fructus lycii drying means, the drying means energy
It is enough significantly shorter drying time, is improved efficiency, the fructus lycii exterior quality after drying is preferable, active constituent content is high, aqueous
It measures lower.
A kind of fructus lycii drying means provided by the present invention, comprising the following steps:
A takes fructus lycii to be placed on basin,
B heating, vacuumizes, dry；
C is cooled to room temperature, obtains dried wolfberry.
Disposing way of the fructus lycii on basin is preferably spread in a single layer in the step A.Take this disposing way
It makes fructus lycii medicinal material surface area bigger, is conducive to moisture and eliminates, further speed up dry speed.
Heating temperature is 35~50 DEG C, preferably 45~50 DEG C in the step B.Drying temperature is excessively high, influences appearance, temperature
It is too low to will affect dry speed.
The dry time is 20~40h, preferably 25~35h in the step B.Drying time is too short to be not achieved and removes fructus lycii water
The purpose divided, drying time too long meeting waste of energy, improves production cost.
Dry vacuum degree is 0.05~0.09MPa, preferably 0.07~0.08MPa in the step B.
Further, a kind of fructus lycii drying means provided by the present invention, comprising the following steps:
A takes fructus lycii fruit to be spread in a single layer on basin；
B is dried in vacuo about 27h under the conditions of 45 DEG C, and vacuum degree is maintained at 0.08MPa；
C is cooled to room temperature, obtains dried wolfberry.
The method and experiment condition that the present invention uses are obtained by screening, can achieve the purpose that accurately to measure, with
It is down screening and comparison procedure of the invention
1. the measurement of fructus lycii exterior quality
Lycium barbarum polysaccharides and beet alkali content measuring method are according in one page 249 of version of " Chinese Pharmacopoeia " 2015 in fructus lycii
Fructus lycii subitem under measuring method.
Drying mode appearance moisture polysaccharides glycine betaine
Air blast electrothermal drying kermesinus, shrinkage 10% 6% 3.5%
Kermesinus of drying in the shade 14% 13.1% 6%
Vacuum drying is bright red, full 5% 15% 10%
As upper, it is apparent that drying time used in fructus lycii medicinal material obtained by vacuum drying method is shorter, medicinal material water content compared with
Low, fructus lycii medicinal material Lycium barbarum polysaccharides and beet alkali content are apparently higher than other methods, and red is presented in medicinal material appearance luster, outside
It is preferable to see quality.
Beneficial effects of the present invention are
(1) it can be significantly shorter drying time, improved efficiency, product quality is high；
(2) the fructus lycii color glow in appearance after drying, active constituent content is high, and water content is lower.
