For a long time, the commonly used sterilization methods for traditional Chinese medicine raw powder in China include traditional heating drying and sterilization methods, such as wet heat sterilization, dry heat sterilization, ethylene oxide sterilization, microwave sterilization, and cobalt 60Co sterilizationWait for the sterilization of native Chinese medicine powder. Here is a brief description of these methods：

moist heat sterilizationSterilization temperature 121 ℃, sterilization time 30-60 minutes; But a considerable number of traditional Chinese medicine ingredients are sensitive to heat, such as volatile oils, easily oxidizable components, and enzymes. For traditional Chinese patent medicines and simple preparations with rich ingredients, steam will lead to degradation and destruction of ingredients, resulting in reduced efficacy and even toxic and side effects. This method not only has low thermal efficiency utilization, long heating time, but also occupies a large area. At the same time, sterilization should be carried out under pressure and at a high temperature of 121 ℃ for 30-60 minutes, which will inevitably damage the efficacy and nutritional components of the medicine to a certain extent.

dry heat sterilizationThe sterilization temperature is 110-120 ℃, and the sterilization time is 2-4 hours. The disadvantages of this method are high temperature, long time, weak penetration of dry heat, uneven sterilization effect, and loss of volatile components up to 25-40%. The color of the produced honey pills becomes lighter and harder, which does not meet the quality standards.

Ethylene Oxide(EO)：Sterilization can penetrate micropores and reach the corresponding depth inside the product. But the disadvantage is that it is flammable and explosive, and the residue can cause variability, which limits its use in pharmaceuticals.

Microwave sterilization:Due to its dependence on thermal effects, it is not suitable for most thermosensitive drugs, and this method has a high sterilization effect and affects the quality of the finished product

Water related, too dry does not have good results; Continuing to dry after sterilization due to excessive humidity may cause secondary pollution.

cobalt60CoRadiation sterilization:There is no standard for the qualification certification of irradiation devices. Improper control of radiation dose can cause vitamin damage, discoloration, and taste change in drugs, and may even lead to decreased efficacy and the induction of carcinogens. In addition, the complexity of radiation equipment, high protection requirements, expensive cost, and difficult maintenance make it difficult to promote and apply in practical production.

It is necessary to find an effective technology to control the bacterial contamination of native medicinal powder in order to ensure the quality of traditional Chinese medicine preparations and accelerate their commercialization.

WanchuangThe technology research and development team conducted a systematic study on the properties of traditional Chinese medicine raw powder, the effectiveness and economy of sterilization methods, and the integrity and stability of sterilized raw powder. A new technological product has been developed based on the principle of microbial thermal lethality and how to maintain the integrity of the original medicinal powder to a maximum extentInstant sterilization of traditional Chinese medicine powderequipment！This device has dozens of technologies，Not only can it kill bacteria, molds, Escherichia coli, etc. in the original powder of traditional Chinese medicine, meeting the requirements of sterility assurance, but it also better maintains the integrity and stability of the original powder of traditional Chinese medicine.

The principle and process of high-temperature instant sterilization of powder raw materials and high-temperature sterilization of milk liquid are *. However, due to the differences and disparities in their physical properties, there are significant differences in the specific details, sterilization equipment used, and requirements for steam heat sources.

Generally speaking, there are the following requirements for high-temperature instant sterilization equipment for powder raw materials:

1. The raw materials need to be heated to above 150 ℃ in an instant, and the heating should be uniform.

2. Once sterilization is complete, immediately cool to room temperature to reduce the loss of efficacy of the original powder.

3. During the entire sterilization process, there must be no clumping or adhesion of raw materials.

4. The equipment should be sealed and there should be no secondary contamination after sterilization.

Characteristics of instant sterilization and drying:

• Maintain the effective ingredients in materials: drying and sterilizing thermosensitive materials such as food and pharmaceutical raw materials;

• Drying speed is higher than hot air drying; The product has a lower moisture content and higher sterilization efficiency;

• It can utilize the latent heat of steam, with high thermal efficiency and energy saving*

• Drying efficiency, reducing drying energy consumption, minimizing environmental pollution, and improving product quality;

• Processing in a low oxygen environment can inhibit the decay and oxidation of food; Capable of vaporizing residual pesticides?
