Speed Chain Conveyor Systems is one series of our Conveyor Systems , is also named pallets conveyors. The Home Appliance Assembly Line, like Tv Assembly Line, computer Assembly Line , oven assembly line are usually designed to Speed Chain Conveyor systems. In the speed chain conveyor systems, the semi-finished products on the pallets is driven by free flow chain, goes through every work station to fix all components into a completed products. The special structure of free flow chain make it continuously running but at the same time every work station can be stopped independently by manually controlling the stopper cylinders. This movement of the speed chain conveyor systems is convenient to operate and can make sure one assembling process are finished before next process. We can design the speed chain conveyor systems according to your products and your plant. Welcome to contact us for detail discussion.

Traditional Chinese medicine has good prospects for development, and modernization of traditional Chinese medicine is an important way to enhance the industry. In order to comply with industry trends, many pharmaceutical companies have begun research and development and production of mechanical products in line with market demand.
The author has learned that the current application of spray dryer in China's traditional Chinese medicine pharmaceutical industry is relatively extensive. Its fast drying speed, stable quality and other characteristics, can save the concentration, filtration, grinding and other processes, have a good impact on the product's liquidity and instant solubility. The spray drying technology not only greatly simplifies the process of extracting traditional Chinese medicines into semi-finished or finished products, but also shortens the production cycle and improves the production efficiency and product quality. In addition, the technology has been combined with fluidization, micro-encapsulation, and coating in recent years, making its application in the field of traditional Chinese medicine expanding and playing an enormous role.
In the extract of traditional Chinese medicine, spray dryer also has a crucial influence. The author was informed that in the spray drying process of Chinese herbal extracts, it is necessary to pass initial, medium-efficiency filtration to clean clean air with grade 100,000. After being heated by the steam heat exchange and electric heating, the heat is heated to the corresponding required temperature, and then it is led to the hot air distributor and distributed evenly before entering the tower. The corresponding material is supplied by a feed pump to a centrifugal atomizer located at the top of the drying tower. Atomization into droplets, and then evenly sprayed into the drying tower, with a good distribution of hot air, convection over a large area, instantaneous drying molding, to obtain powder or granular products.
However, the spray dryer also faces a big problem in Chinese herbal extracts, that is, sticky and dry products tend to absorb moisture during the drying process, and it is difficult to handle high-concentration, high-viscosity Chinese herbal extracts. Some studies have shown that the softening point of Chinese herbal extracts is lower than the air temperature of spray drying, which is the main cause of sticky wall phenomenon. By adding auxiliary materials to improve the softening point of the extract, the sticking phenomenon can be eliminated, but the addition of auxiliary materials may affect the purity of the product. . In addition, another drawback of spray drying is that the product recovery rate is lower than that of drying technology. Industry and companies should pay attention to this.
Some experts also stated that China's traditional Chinese medicine extract drying technology needs to further strengthen the basic theoretical research, consolidate applied research and application development technologies, and strengthen innovations in drying degreeization, testing techniques, manufacturing processes, and exterior design. .
In the face of fierce market competition and unfavorable environmental factors, related pharmaceutical companies must pay attention to international exchanges and cooperation, and must also pay attention to the protection of intellectual property rights; they must try new technologies, develop new applications, and strengthen Innovation and innovation in traditional processes and traditional applications. For now, customers and markets favor high-quality, low-energy, environmentally-friendly machinery and equipment. Therefore, companies need to gradually adjust the product structure, cultivate and play a competitive advantage, use high-quality products and sincere services to win the trust of customers, so as to lay the foundation for the good development of enterprises and industries in the future.
Chinese medicine extract drying technology needs to be further strengthened
With the surge of “return to nature†and the deep understanding of the side effects of chemicals, the acceptance of Chinese medicine in the international market is gradually increasing. From some developed countries, such as the United States, Japan, etc., the application and production of Chinese medicine can be seen that Chinese medicine is increasingly welcomed by the international market, which also creates a vast space for internationalization in the future.
