China Drying Network News Drying is the last step in the production of tablets from the extraction of raw materials to the semi-finished dry paste products. The application of drying equipment and technology is directly related to product quality. In the production of tablets, the other links are even better controlled. If there are problems such as uneven drying, destruction of active ingredients, and thermal deterioration in the drying process, the quality of the tablets will eventually be at a disadvantage.
The vacuum continuous drying equipment and technology have the advantages of low temperature drying, less destruction of active ingredients, looseness, easy dissolution, absorption, drying, and sterilization at the same time, thereby ensuring that the product has high active ingredients, high sterility index, and good oral absorption. Therefore, the vacuum continuous drying method has many unique advantages compared with currently used oven drying methods, spray drying methods, etc., and can guarantee that the product quality is much higher than that of other drying methods.
The vacuum continuous drying method has the following four main characteristics: Low-temperature drying In a vacuum environment, the boiling point of moisture is reduced, and low-temperature drying can be achieved, which provides favorable conditions for the drying of heat-sensitive materials and can effectively avoid the active ingredients of the products during the drying process Destroyed by high temperatures. For example, when producing natural extracts, the product is in a vacuum and closed environment throughout the drying process, and the drying process is mild (temperature 40°C to 60°C) to maintain its active ingredients to the maximum. Oxygen-differentiated vacuum environment, the oxygen partial pressure is reduced, to avoid the phenomenon of material degradation in the drying process, to protect the quality of the product being dried. Loose micropores Under high vacuum conditions, after the product has been gradually dried over a period of time, there are micropores in the microscopic structure, and after the particles are directly crushed to the required particle size, the particles have good fluidity. At the same time, due to the microscopic loose structure, the particles are extremely fast-dissolving and are More conducive to human body absorption. Simultaneous sterilization in the vacuum hypoxia state, can effectively inhibit the proliferation of bacteria to achieve the purpose of killing bacteria. While drying the product, sterilization can be achieved again. Double sterilization ensures that the product is aseptic.

Vacuum drying equipment
Vacuum drying equipment is designed to dry heat-sensitive, easily decomposable and easily oxidized materials. It can be filled with inert gas. In particular, some complex components can also be quickly dried. Vacuum drying box design is perfect, the box body is processed by CNC machine. The test chamber liner adopts SUS304 stainless steel plate, and the outer shell is A3 plate spray treatment, which is more smooth and beautiful. The door opening of the circuit system is adopted for easy maintenance and overhaul. The closed tightness of the door can be adjusted, and the integrally formed silicon rubber door seal ensures high vacuum inside the box. Storage, heating, testing, and drying are performed in the absence of oxygen or in an atmosphere filled with inert gas, so they do not oxidize.
