Powder Handling / Transfer Systems for Pharmaceutical Industry

Pharmaceutical Industry

Raw material handling

In Pharma Industry the process of charging raw material through small bag can be done by Bag Dump Station with inbuilt Lump Breaker and Suction tool system, for Big Bag, Big Bag Unloading Station can be used. Inbuilt dust extraction system minimizes airborne particles/ dust nuisance, ensuring a dust free environment and the material is then transferred to downstream, after passing through a vibro screen. The process is designed to ensure operator safety, avoid contamination, and comply with GMP standards. This method provides a controlled, efficient, and clean way to transfer bulk materials into the processing system through PTS/VTS (Powder transfer system/Vacuum Transfer System).

Wet cake or wet material Transfer

After drying, the dried material, with some moisture percentage, also called as wet cake, is transferred to the next stage using a VTS. The VTS is a closed pneumatic conveying system that safely transfers the dried powder from the dryer to downstream processing equipment, such as a multi-mill, without exposure to the environment. This closed system ensures that the product remains free from any atmospheric contamination during transfer. It is particularly useful in handling toxic or highly potent materials, as it minimizes the risk of exposure to operators and the environment or any oxidation process. Once the material has been transferred by the PTS/VTS, it is processed in a multi-mill. A multi-mill is type of mill used to reduce size and homogenize the dried material. The speed of rotation and the size of the screen in the multi-mill can be selected to achieve the required particle size distribution. The output from the multi-mill is a milled finely and with consistent band width for further processing.

Sieving / Shifter

The milled powder is then passed through a vibro sifter, which ensures that the final product has a uniform particle size, which is crucial for downstream processes like blending, granulation, or tablet compression. The separated fine powder is further proceeded, and oversized particles are recycled back to the multi-mill upto further accepted size reduction.

Pack-Off

After sifting, the fine powder is once again transferred using a VTS to the final processing or packaging area. The pack-off machine is designed to fill, seal, and label the product into various types of packaging, such as bags, drums, or bottles, depending on the product and tended use. During the pack-off process, the powder is typically fed into the packaging machine from a storage hopper, where it is weighed and dispensed into the packaging. The pack-off machine may include features such as vacuum sealing, nitrogen flushing, or other forms of protective packaging to ensure the stability and shelf-life of the final product. Each step is designed to maintain product quality, safety, and pharma compliance with pharmaceutical industry standards.
