Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine extraction, and in particular to a preparation process and a preparation system for quick-injection traditional Chinese medicine powder. Background Art

[0002] Chinese medicine refers to medicines used under the guidance of traditional Han medicine. Chinese medicine is divided into Chinese patent medicine and Chinese medicinal materials according to the processing technology. Chinese medicine mainly originated in China. In addition to plant medicine, animal medicine such as snake gall, bear gall, five-step snake, deer antler, deer horn, etc.; shells such as pearls; minerals such as dragon bones and magnets are all Chinese medicines used to treat diseases. A few Chinese medicines originated from foreign countries, such as American ginseng.

[0003] Due to factors such as air, temperature, time and bacterial contamination, the enzyme decomposition in the liquid medicine is ineffective, bacteria multiply and breed, and starch, sugar nutrients and other ingredients are fermented and hydrolyzed, so that the liquid medicine becomes sour and deteriorates, which is harmful to human health after taking it. Therefore, Chinese medicine should not be taken overnight. Traditional Chinese medicine is mostly taken as soon as it is decocted. In order to facilitate the preparation and taking of Chinese medicine, pharmacies currently mostly use Chinese medicinal materials to boil in batches and then store the Chinese medicine decoction in several plastic bags, bottles or cans. However, the storage of liquid Chinese medicine decoction takes up a large space, is inconvenient to store or carry, and needs to be heated in a water bath or microwave before taking each time. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects in the prior art and provide a preparation process of quick-made Chinese medicine powder, which can prepare Chinese medicinal materials into Chinese medicine powder that is easy to carry and take, and the operation steps are simple and easy. The system consists of equipment such as decoction, filtering and drying, which ensures the application implementation and automatic control of the Chinese medicine powder preparation process.

[0005] To achieve the above object, the technical solution of the present invention is to provide a preparation process of quick-release Chinese medicine powder, comprising the following steps:

[0006] S1: Soaking, weighing the Chinese medicinal materials of various components according to a certain weight ratio, placing the Chinese medicinal materials to be soaked in a decoction kettle, adding pure water 2 to 3 cm above the upper surface of the Chinese medicinal materials, setting the soaking temperature through the controller, starting the ultrasonic generator and the heating element, and ultrasonically soaking the Chinese medicinal materials at a certain temperature for 20 to 40 minutes;

[0007] S2: decoction, according to the decoction requirements of the Chinese medicinal materials, the corresponding Chinese medicinal materials are put into the decoction kettle at once or in stages, the ultrasonic generator is turned off by the controller, and the heating rate of the decoction kettle is set, and the heating element, stirring device and air inlet valve switch in the decoction kettle are started, so that the Chinese medicinal materials in the decoction kettle are kept in a slightly boiling state for 1 to 2 hours under an inert gas atmosphere to obtain a medicinal liquid mixture;

[0008] S3: Filtration, opening the discharge port at the bottom of the decoction kettle, allowing the liquid medicine mixture in the decoction kettle to enter the filtering device through the discharge port for filtration, obtaining drug residues and Chinese herbal medicine decoction, wherein the Chinese herbal medicine decoction enters the buffer tank for storage;

[0009] S4: Processing, the rotation speed of the rotary atomizing nozzle of the centrifugal spray drying device, the temperature of the drying hot air and the air inlet speed are set through the controller. When the hot air temperature reaches the set value, the liquid transfer pump is started to continuously pump the Chinese herbal medicine decoction in the buffer tank to the rotary atomizing nozzle. After being dried by hot air, the Chinese herbal medicine decoction enters the cyclone separator for separation, and the Chinese herbal medicine powder enters the product collection chamber, and the exhaust gas is discharged by the induced draft fan;

[0010] S5: Packaging: The Chinese medicine powder in the product collection room is packaged in bags according to the dosage requirements.

[0011] The soaking process in this process adopts ultrasonic vibration, which effectively shortens the soaking time of medicinal materials from the traditional 60 minutes to 30 minutes to achieve the traditional soaking effect; the decoction process adopts inert gas protection, which effectively avoids the contact between the medicinal materials and the outside air during the decoction process, and ensures the efficacy of the Chinese medicine powder; the processing process adopts a centrifugal spray drying device to dry the Chinese medicine decoction, which ensures the drying efficiency of the Chinese medicine powder, and the powder particles are uniform and loose, which is easy to take; the Chinese medicine powder is packaged in bags according to the dosage, which is convenient for quantitative taking at a later time.
