Main purpose:
This machine is suitable for pressing double-layer and three-layer tablets, and can compress granular raw materials into tablets. It is mainly suitable for tablet production in the pharmaceutical industry, and also applicable to industrial sectors such as chemical, food, and electronics. According to the ordering requirements, it can press round pieces, irregular pieces, and double-sided engraved pieces.
ZPB-31Automatic rotary tablet press Features:
1. The outer shell is fully enclosed and made of stainless steel, while the inner tabletop is made of stainless steel, which can maintain surface gloss and prevent cross contamination, meeting GMP requirements.
2. Equipped with a transparent protective cover, the status of the tablet can be clearly observed, and the side panel can be fully opened for easy internal cleaning and maintenance.
3. All controllers and operating components are arranged reasonably, and a human-machine interface variable frequency speed regulation device is used for electrical speed regulation and reverse rotation.
4. Easy to operate, smooth rotation, safe and accurate. Implement mechatronics integration, using touch screen PLC control and operation.
5. The transmission system is enclosed in the oil tank below the machine body, which is a separate and independent component that does not contaminate each other. It is easy to dissipate heat and wear-resistant.
6. The machine is equipped with a vacuum cleaner, which can absorb and clean the dust flying in the suppression room.
7. This machine has high pressure and can adapt to the production of various large, small, and difficult to form tablets, making it an ideal equipment for tablet production.
