pneuCONVEYOR – Octagonal Blender is a very precision machine, performing dry blending of powder or granules homogenously in only 10 to 30 minutes. This machine is utilized for mainly homogenizing, blending and also for granules lubrication as that facilitates better flowability at a tablet press while compressing this granules. Due to its octagonal shape is designed to process larger volume of material. It occupies less space compared to other similar blenders like ‘V’ / Double Cone. The blending takes place at low speed during operation. It is well balanced & smoother even in higher capacities. It is very useful for pharmaceutical industries wherein gentle blending of dry granules of powder is to be done.
The important feature of the machine is easy to wash in place. Octagonal blender is supplied with a bin charging system or can be designed for vacuum charging. Dust free charging system is also incorporated, which is a completely closed system for charging and discharging of powders or granules.
The power consumption is comparatively lower than other similar type of blenders. Basic machine consists of a blender container which is supported both ends by stub shafts which are supported on plummer block bearings. Entire assembly is placed on a structure which has drive unit consisting of electric motor, chain coupling and in case of heavy loads fluid couplings. All parts coming in contact with mix are of stainless steel 316 quality and are highly polished. Drive motors, electrical control panel and control station are supplied in non-flameproof as well as flameproof construction, as per clients requirement. In case of flameproof construction, the control panel should be located in low risk area.
There is a baffle made of ss316 pipes inside which can be removed by losing the nut between the baffles. Baffles assembly also depends upon the customer’s specific requirements. Baffle ensures uneven movement of mass during tumbling and results in better homogenising. Blender has a discharge butterfly valve which if a client requires so can be operated through pneumatic actuators. Entire butterfly valve is of SS316 with seats of silicone rubber
The whole drive assembly is covered with S.S. side panel. All drives, pulleys and belt are adequately guarded. Interlock is provided for the railing so that operator does not have access to the container when it is in motion. Machine will stop automatically once the blender main railing is made to open.
The inside of Octagonal body is mirror polished and the outside surface is matt polished. The material to be mixed is charged in machine either manually from top or bin charging system or vacuum charging system and then the port is locked positively. Then blender is started to preset blending time. At the end of process, machine is stopped and the product is transferred to process containers by opening the butterfly value.
There are three methods to load Blenders.
Pneumatic Automatic powder charging system is provided duly mounted on a swivelling davit interlocked with sensor to safeguard against blender. It is provided with a SS suction nozzle coupled to a flexible PVC food quality conveying pipe to enable for direct suction of the powder from container which will be discharged in blender and on complete charging of batch or maximum upto 70-80% by volume, filter bag of charging system may automatically be cleaned by auto reverse pulse jet mechanism thereby safeguarding against operator dependency, charging system may be swivelling on side and locked in that position which will actuate the sensor for that position, a dummy cover to be clamped on charging hole & homogeneous blending action can be initiated by starting the blender operation. After necessary blending period the material can be discharged & collected from bottom into container by manually opening the butterfly valve. The entire auto charging system is a tool free assembly.
