Introduction of pharmaceutical vibro sifter
Pharmaceutical vibro sifter is dedicated to screening, sieving, grading for solid-liquid separation in the pharmaceutical industry. It is separated from the combination of liquid materials, and can be used for screening and removing impurities of acidic, alkaline, oily and other medical drugs such as pharmaceutical intermediates, medical excipients, traditional Chinese medicine powder, traditional Chinese medicine liquid, western medicine powder, and western medicine liquid. The equipment complies with the requirements for pharmaceutical equipment in the "Good Manufacturing Practice for Pharmaceutical Products" revised in 2010.
The whole machine is made of polished 304/316L stainless steel. The inside and outside of the screen are polished. The bouncing balls and seals are made of non-toxic and non-polluting silicone material. It is designed and produced in strict accordance with the hygienic standards of the pharmaceutical industry. The screening accuracy is high. Safe and hygienic, it is suitable for screening and filtering various medical materials, fine powder, micro powder, dry and wet materials, etc.
Application of pharmaceutical vibro sifter
Pharmaceutical vibro sifter is often used for impurity removal of raw materials, grading of oral granules, powder removal of tablets, screening of pills, etc. Its application scenarios mainly include:
1. Pharmaceutical powder: During the screening process of pharmaceutical powder, there are many problems such as excessive fiber, high viscosity, static electricity, and light specific gravity, which will lead to low screening throughput, weak continuous work, inconvenient cleaning, and low production efficiency. The ultrasonic deblinding system is adopted to effectively solve the above problems and reduce the network blocking phenomenon. For materials with light specific gravity and good adsorption, it can improve production efficiency, improve screening accuracy, greatly reduce labor intensity, and reduce waste of finished materials.
2. Drug granules: Generally, the fineness of Chinese and Western medicine granules should be able to pass through a 10-50 mesh sieve, but the fine particles that cannot pass through a 10-mesh sieve and a 65-mesh sieve should not exceed 8%.
3. Medicinal extract: After the liquid is roughly filtered from the storage tank, it enters the vibro sifter, and the smallest filter screen can pass through 625 mesh (20 microns). The machine itself has an automatic slag discharge function, which can be used continuously to eliminate screen blockage and achieve continuity. At the same time, it can improve the recovery rate and reduce the labor intensity of workers. In the pure settling process, if not used, the effective liquid will be lost with the residue. After use, the finished slurry in the slurry can be effectively recovered, and the waste residue treatment is drier and less polluted.
Sieving process of pharmaceutical vibro sifter
The main purpose of the pharmaceutical vibro sifter is to perform grading and impurity screening. The vibro sifter sieves layer by layer through screens of different meshes. The material (coarse material) with hole size stays on the screen surface and is discharged from the discharge port to achieve effective grading and screening of pharmaceutical products. Coupled with the vibration force of the vibration motor, it effectively solves various screening problems encountered in the biopharmaceutical process. question.
