Embodiment 1
[0060] Carry out sulfur fumigation to Fritillaria japonicus, the specific sulfur fumigation steps of Fritillaria japonicus are as follows figure 2 Shown specifically as follows:
[0061] 1) Place 1kg of Fritillaria evenly in the sulfur fumigation box;
[0062] 2) Place 1g of sulfur in the sulfur chamber;
[0063] 3) Fill the water tank with clean water;
[0064] 4) Turn on the power and the air pump to make the fumigation box reach a vacuum state;
[0065] 5) Ignition of sulfur;
[0066] 6) Through the control panel, set the temperature of the temperature controller to 5°C and the fumigation time to 1 hour; at the same time, monitor the air pressure in the fumigation box through the control panel;
[0067] 7) Turn on the temperature controller, and let the sulfur dioxide enter the temperature controller; control the temperature of the sulfur dioxide at 5°C through the temperature controller, and enter the medicine fumigation box through the sulfur dioxide inlet for fumiga...

Abstract
The invention relates to the technical field of processing of traditional Chinese medicine materials, in particular to equipment and a method for sulphur fumigation of traditional Chinese medicine materials and medicinal slices. The method is characterized by comprising the following steps: 1) placing the traditional Chinese medicine materials, i.e. uniformly paving the traditional Chinese medicine materials to be subjected to fumigation in a sulphur fumigation box; 2) adding sulphur proportionally according to the amount of the added traditional Chinese medicine materials; 3) burning the sulphur, setting temperature, time and air pressure in the fumigation box, and subjecting the traditional Chinese medicine materials to fumigation by adopting vacuum and low temperature; 4) monitoring and adjusting temperature and concentration of sulfur dioxide as well as the air pressure in real time; and 5) absorbing and processing sulfur dioxide waste gas. According to the method and equipment for sulphur fumigation of the traditional Chinese medicine materials, controllable operation of the sulphur fumigation process of the traditional Chinese medicine materials is realized. Through controlling key factors such as temperature, concentration of oxygen and sulfur dioxide and the like in the fumigation process, the loss of active ingredients in the traditional Chinese medicine materials is reduced, and the residual quantity of sulfur dioxide and heavy metal in the traditional Chinese medicine materials can be controlled, therefore, the quality of the traditional Chinese medicine materials can be ensured to the maximum degree. The equipment has the characteristics of convenience in operation, controllable fumigation parameters, low cost, convenience in generalization and the like.
Description
[technical field] [0001] The invention relates to the technical field of processing Chinese medicinal materials, in particular to a sulfur fumigation device and method for Chinese medicinal materials and decoction pieces. [Background technique] [0002] Food-grade sulfur is used for bleaching and antisepsis in food production. It is a legal food additive bleaching agent allowed by the country. Applying sulfur to the field of processing and maintenance of Chinese medicinal materials can effectively realize the moisture-proof, anti-corrosion, and anti-corrosion of Chinese medicinal materials. Anti-insect, anti-bacteria and other effects. Through chemical analysis and research, it is found that sulfur dioxide and sulfuric acid produced in the sulfur fumigation process are the main factors for moisture resistance, anti-corrosion, insect resistance, anti-bacteria and bleaching. The occurrence of the reaction requires the participation of oxygen and high temperature conditions. F...
