Problems and Solutions of Tablet Pressing Machine (Ⅰ)

Tablet Pressing Machine is a common Pharmaceutical Equipment. The following simple introduction tablet press a sticky blunt the cause and the treatment methods: rush is refers to the pressure for a tablet surface fine powder is the punch and die adhesion, led to dent, one-sided, not only uneven lettering punch are more likely to happen to glue phenomenon.
1. Insufficient dosage of lubricants, improper selection and excessive fine powder. The dosage of lubricant should be increased or new lubricant should be replaced to remove excessive fine powder.
2. Unreasonable design of engraving and stamping characters. Replace punch or change character design accordingly.
3. Excessive water content of particles or uneve
n dry and wet particles cause viscidity. Solution: control the water content of granule at 2%~3%, strengthen the inspection of dry granule.
4. Viscidity due to the material itself (such as the ability to attract moisture). Solution: add a certain amount of absorbent (e.g., 3% calcium hydrogen phosphate) to avoid sticking.

Parameters To Be Controlled In Fluid Bed Dryer

图片
Fluidized bed dryer (also referred to as  Fluid Bed Dryer ) is a sort of equipment utilized widely in the pharmaceutical businesses to decrease the moisture content of pharmaceutical powder and granules. In fluidization procedure, warm air is released in high pressure through a perforated bed of moist sound particulate. The moist solids have been raised from the ground and suspended in a flow of air (fluidized condition ). Heat transfer is achieved with direct contact between the moist strong and warm gases. The vaporised liquid is taken off from the drying gasses. Sometimes to conserve energy, the flow gas is partly recycled. To be able to boost performance, efficacy, and reproducibility of a fluidized bed drier, a few parameters will need to be controlled.  Fluid Bed Dryer Manufacturer  will tell you its parameters. Device parameters: People controlled by the equipment. Procedure parameters: People controlled by the Process. Merchandise parameters: People contr...

High Speed Development Trend of Roller Compactor

图片
Pharmaceutical is a complex process, which requires many processes, and  High Quality Roller Compactor  is an important part of it. Therefore, the role of  Roller Compactor  in the pharmaceutical industry is very obvious. With the development of the pharmaceutical market, the requirement for pelletizer is increasing day by day. Roller Compactor is a kind of swinging action of rotary drum. It can grind wet powder raw materials into granules by wire sieve. It can also be widely used for grinding granules which have become lumps and ready-made granules. A lump formed during lump forming or during chemical processing. With the continuous development of the industry, roller compactor machine began to emerge. It is a new roller compactor method developed after the second generation granulation method. it is an environmental friendly granulation process. it is a new equipment for directly pressing powder into granules. We are  Roller Compactor Manufacturer ...
