Problems solved by technology

[0006] 1. The thermal energy effect generated in the confined space and the space outside the barrier form a temperature difference and a humidity difference, which makes the water vapor in the confined space adsorbed on the surface of the Chinese herbal medicine, resulting in secondary pollution of the Chinese herbal medicine;
[0007] 2. The overheating reaction itself will accelerate the volatilization of the internal oil of some Chinese medicinal materials, making it lose part of its medicinal value;
This maintenance method has many deficiencies in the current field of traditional Chinese medicinal materials maintenance. Its application rate and response in the industry are not high. Secondly, the maintenance cost is quite high. Some small enterprises and individuals cannot afford the high maintenance cost, so in the end Still haven't solved the substantive problem

Embodiment 1

[0061] Embodiment 1 A method for modularizing and classifying nitrogen storage of Chinese medicinal materials, comprising the following steps in turn:

[0062] (1) Bottom laying: According to the types of medicinal materials, delineate different stacking areas in the stacking area and mark the stacking positions, and lay a layer of thatch on the corresponding stacking positions respectively. Keep the same area; lay a layer of old sacks on the tarpaulin, and then lay a layer of film on the old sacks to form the bottom of the warehouse. The area of ​​the film laid on the bottom of the warehouse is larger than the area of ​​the stacking position, and the edge of the film exceeds the stacking position by 20 -30 cm.

[0063] (2) Lay a layer of old sacks on the film at the bottom of the warehouse to prevent the bottom of the film from being pierced when stacking, and then stack the Chinese medicinal materials to be stored on the old sacks, stacking from the inside to the outside, A...

Embodiment 2

[0101] Embodiment 2 A method for modularizing and classifying nitrogen storage of Chinese medicinal materials, the steps are as follows:

[0102] The storage experiment was carried out according to the same method as in Example 1, except that the Chinese medicinal material was: Epimedium, the storage start time: 2016 / 07 / 02, the storage end time: 2016 / 12 / 31, and the experiment period was 6 months. Storage method: scattered storage of single species.

[0103] In this embodiment, the product name and quantity distribution of Chinese medicinal materials are shown in Table 7:

Embodiment 3

[0131]Embodiment 3 A method for modularizing and classifying nitrogen storage of Chinese medicinal materials, the steps are as follows:

[0132] The storage experiment was carried out according to the same method as in Example 1, except that the storage start time: 2017 / 01 / 19, the storage end time: 2018 / 01 / 18, and the experiment period was 12 months. Storage method: scattered storage of multiple varieties. The performance of the sealed chamber used in this example after sealing is as follows: oxygen transmission rate OTR and nitrogen transmission rate are both less than 10.2 (cc / ㎡·24h·0.1Mpa), moisture permeability is less than 8.3 (g / ㎡·24h), sliding The coefficient of friction is not less than 0.17, the haze is not less than 19.50%, the average thickness is not less than 120.82 (μm), the ultimate thickness is 115-120 (μm), and the longitudinal and transverse impact rupture strengths are 524 and 553 (0.1mpa) respectively , The heat seal strength is not less than 53.72 (N / 15mm...

Abstract

The invention belongs to the technical field of warehousing of traditional Chinese medicinal materials and particularly relates to a traditional Chinese medicinal material maintenance method adoptingnitrogen storage. Traditional Chinese medicinal materials are sealed by a gas-tight silo to be isolated from outside natural gas environment, nitrogen is injected into the gas-tight silo by movable pressure swing adsorption separation type nitrogen generating equipment, and an automatic pumping and filling linkage system which is arranged outside is in charge of discharging replaced gas outwards from the gas-tight silo. The method has the main advantages as follows: oxygen decreasing speed is high, insect pests can be eliminated within short time, and loss caused by the insect pests for the traditional Chinese medicinal materials can be reduced; the preservation effect is realized through continuous low-oxygen storage, phenomena such as autoxidation, weathering, color change and bleeding of the traditional Chinese medicinal materials can be relieved sufficiently, and accordingly, the storage period of the traditional Chinese medicinal materials is prolonged.

Description

technical field [0001] The invention belongs to the technical field of storage of traditional Chinese medicinal materials, and in particular relates to a maintenance method for traditional Chinese medicinal materials stored in nitrogen. Background technique [0002] There are many kinds of Chinese herbal medicines with complex ingredients, mostly containing starch, sugar, oil, protein and other ingredients. If they are not stored properly and there is no reasonable maintenance technology, they will be moth-eaten, moldy, oily, discolored, weathered, spontaneously combusted, sticky, Problems such as loose gas and odor, thereby affecting its medicinal value and medical quality, causing unnecessary waste, and also bringing direct economic losses. [0003] The nitrogen storage technology currently used was initially based on the storage method of the fruit and vegetable industry, and was derived through continuous research and development, improvement, and upgrading. Its predeces...
