Application examples and advantages of vibrating screen in the pharmaceutical industry
The pharmaceutical industry vibrating screen, also known as the medical vibrating screen, generally uses a round full 304 stainless steel vibrating screen or a standard vibrating screen (the material contact part is 304 stainless steel). This series of vibrating screens absorbs the advantages of domestic and foreign vibrating screen machines. to make. Beautiful shape, reasonable structure and excellent performance. Light weight, small size, low noise, low energy consumption, non-clogging mesh, no flying powder, no leakage of liquid, the direction of the outlet can be adjusted 360 degrees, easy to connect with other equipment, high degree of automation, easy to thoroughly clean and disinfect , Easy maintenance and other advantages. Screening, solid-liquid separation and filtration of various powders and granules of materials to meet different physical requirements such as product uses, required fineness and purity, particle size consistency, stability, uniformity, appearance, etc., to more effectively improve products Quality, improve efficiency, ensure production fluency and easy storage.
Application examples of vibrating screens in various processes in the pharmaceutical industry:
Acetylsalicylic acid, sulfamethoxazole, vitamin C, penicillin potassium, ampicillin, cephalosporin C sodium, Welfare equal powder pharmaceutical raw materials, after sieving, can ensure the consistency of the finished powder particle size, fluffy powder, texture It is uniform, reduces the chance of agglomeration during transportation or storage, and ensures the high quality of APIs.
Second, granule preparation
1. Raw material processing: Separate the raw materials and auxiliary materials, effectively remove large particles and debris, and increase the uniformity of the materials. The original and auxiliary materials are mixed and sieved to make them mixed evenly, mainly distributed evenly, and make the powder combination even and highly fluffy, which greatly increases the effective area of powder and liquid, effectively shortens the mixing time, and lays a good foundation for the production of high-quality medicines.
2. Whole granulation: For granulation after drying, remove large particles and fine powder at one time to ensure that the particle size meets the standard of drug requirements. Large batches of granules are more effective.
Three, Chinese medicine preparations
1. Primary treatment of seed medicinal materials: The primary screens are used at the same time, effectively removing impurities, dust, broken seeds, etc. to achieve the purpose of purifying raw materials at one time. In order to ensure the integrity and rigor of drug formulations, improve the efficacy of drugs, colleagues reduce labor costs.
2. Crushing of Chinese medicinal materials: After crushing, sieving to remove large particles to ensure the consistency of Chinese medicine powder and reach the required fineness. Closed screening, powder does not fly, reduce waste and improve production environment.
3. Filtration of extraction liquid: one-time filtration can effectively separate solid and liquid, and automatically discharge slag, with high efficiency.
4. Various types of traditional Chinese medicine preparations: all kinds of raw and auxiliary materials are sieved before use to remove larger particles and plant fibers, and sieve to loosen into agglomerated powder particles, so that the powder particles are fluffy, the particles are uniform, and the distribution is even, which helps the main medicine to be mixed evenly To produce high-quality medicines.
After tableting, the tablets are sieved to effectively remove the attached fine powder, burrs, loose tablets, and debris, thereby improving the appearance quality of the tablet and making the next process smooth.
Working characteristics of vibrating screen:
1. All parts of the machine that are in contact with materials are made of stainless steel 304 or 316, and the seals are made of silicone material, which is more suitable for pharmaceutical GMP regulations.
2. The sieving process is completely closed, the powder does not fly, the liquid does not leak, and the production environment is improved.
3. The mesh size of the screen can be matched to 500 mesh, and the finest filtering can be up to 5 microns. The whole machine is easy to disassemble and disassemble, without the need of professional technicians.
4. L-shaped grid design. Can be used in single or multiple layers. The structure of the parts has no dead corners and is easy to clean and disinfect.
5. 360 degree adjustment of the direction of the outlet. All screening materials are automatically discharged, suitable for mass production and assembly line production.
6. The mesh is not clogged, and the filtering efficiency is high.
7. According to the production process requirements, it can be specially manufactured.
8. The vibrating screen machine can be equipped with waterproof spring apron to prevent dust from entering the motor and increase the service life of the motor.
