The prospect of traditional Chinese medicine industry is considerable, and the problem of extract drying needs attention

Traditional Chinese medicine is a national treasure in China With the promotion of a series of policies, the industrialization of traditional Chinese medicine in China is developing rapidly, and its related products are also emerging in the international pharmaceutical market According to industry data, the scale of Chinese traditional medicine industry reached 762.9 billion yuan in 2015, more than 800 billion yuan in 2016 and 1317 billion yuan in 2020 So it has a good market prospect In this context, the quality of traditional Chinese medicine products needs to be improved, and the production technology, technology and equipment related to traditional Chinese medicine are also concerned In the production process of traditional Chinese medicine, the drying problem of traditional Chinese medicine extract is more prominent With the development of modern science and technology, some drying equipment came into being Among them, the Chinese medicine extract spray dryer is mainly used for spray drying of Chinese medicine solution into dry powder, which has the advantages of fast drying speed, high efficiency and less process It can keep the color and aroma of heat sensitive materials, and the spray dryer of Chinese medicine extract is widely used in the pharmaceutical industry According to the working principle of the Chinese medicine extract dryer, it is actually the application of centrifugal spray drying technology in drying certain materials It also uses high-speed centrifugal atomizer to disperse the material into fog and fully contact with the hot air, so as to finish instant drying and form powder Compared with ordinary spray dryer, the spray drying machine of Chinese medicine extract is totally enclosed, with higher air level, automatic control and continuous working intensity After being dried by the machine, the traditional Chinese medicine extract powder will not appear coking deterioration, greatly increasing the powder collection rate (more than 95%), and will not produce the phenomenon of drug mixing and wall sticking The spray drying machine of Chinese medicine extract solves the defects of ordinary spray dryer, such as material sticking, low powder collecting rate, coking deterioration, difficult cleaning and low output According to the properties and technological requirements of Chinese medicine extract, the spray drying machine of Chinese medicine extract is designed After drying, the color of the material is good and not deteriorated, which greatly improves the economic efficiency of the factory There are pharmaceutical companies With the increasing market size of traditional Chinese medicine, the industry is becoming more and more standardized, and the use of dryers for traditional Chinese medicine extracts is becoming more and more common In this context, the competition among the dryer manufacturers of traditional Chinese medicine extract is more fierce, and enterprises have to enhance the added value of products in order to win the market competitiveness For example, some manufacturers specially designed and manufactured spray dryer for plant extract and Chinese medicine extract specially for the special characteristics of Chinese medicine extract materials, and developed new equipment combined with advanced foreign similar spray drying technology and long-term experience accumulated by company technicians In the design process of spray drying of Chinese medicine extract, the manufacturer has designed spiral case and hot air distributor for the equipment The purpose is to avoid the phenomenon of vortex pump air flow caused by high-speed rotating atomization disk, resulting in "droplet returning to the top or powder suction" It is understood that the spray drying main tower (rapid progressive structure) hot air vortex shell and hot air distributor designed by the manufacturer can ensure that the atomized droplets do not return to the top, cooperating with a primary air cooling technology to avoid coking deterioration At the same time, the manufacturer has designed a freeze dehumidification receiving device, which can make the material leave the high temperature area quickly and cool down, avoid the softening and caking phenomenon of the material caused by the material staying in the high temperature area of the cyclone separator for a long time, and avoid the phenomenon of moisture absorption and caking of the hygroscopic material In addition, in order to ensure that the materials are not polluted, the whole unit of the equipment is made of stainless steel at the contact with the materials, and the transmission parts in contact with the materials are well sealed, which can be waterproof and oil-proof The discharging place is operated by a sealed butterfly valve to prevent air leakage The air induction and discharging pipe sections are all connected flexibly, which can be disassembled, cleaned, disinfected and sterilized at any time.
