Rapid Mixer Granulator

Construction of the Machine

Rapid Mixer Granulator is developed for mixing of ingredients as well as wet granulation required for tablet/ capsule manufacturing process. This is achieved by reduced processing time, more homogeneous mixing, and uniformity of granule size and above all maintaining improved hygiene compliant to cGMP norms.

Mixing Bowl

It is circular with a large diameter and flat base. The top portion of the bowl is conical in shape to assist mixing of cohesive powders. Constructed from SS 316/ 316L. A large diameter tube surrounds the drive shaft where it enters the base of the bowl.

The main drive, shaft seal is on the top of tube and thus well above the normal powder level. The Shaft seal is provided with automatic air purge.

The seal housing and drive shaft may be flushed with cleaning water, which is then drained away from the machine through built discharge port.

The multi-bladed impeller is fitted close to the base of the mixing bowl whereas the chopper is mounted on the wall of the mixing bowl. Both the impeller & the chopper have dual-speed options for gently distributing the binder solution as it is added and creating the vortex of the material being mixed.

Granulator

A high speed granulator is located so as to assist blending of powder and to break the product to granule of required size.

The granulator rotates at two speeds 1500 or 3000 RPM. The granulator head is of highly polished stainless steel and is easily removable for cleaning.

The Granulator Shaft where it enters the bowl incorporates AIR PURGED SEAL.

The motor is provided with a removable stainless steel covers to meet cGMP norms.

Online Co- Mill

The online CO-Mill is provided on the discharge port to reduce the oversized lumps. Resulting in reduced drying time by approximately 20%. As the lumps are small product can be uniformly dried at lower temperature. Thus giving it a longer shelf life beside eliminating caseing & capping of tablet due to improper drying.

Side Discharge Valve

It is provided on the side of the bottom, operated by ASS. Spindle connected to pneumatic cylinder in closed position. The gate is flushed with the contour of the bowl.

A cover with removable silicone rubber seal gives unrestricted access into the chute for easy cleaning.

A safety lock in the form of a limit switch is provided at the discharge port to prevent the valve or the motors to start during the cleaning operation.

The pneumatic cylinder is covered with stainless steel shroud to meet cGMP standard.
