FILLING A BLENDER WITH A QUADRO VAC
 

Problem

A large pharmaceutical customer was looking for a conveyor to fill their V-blenders with powdered ingredients of varying bulk densities. They had purchased a pneumatic conveyor for conveying one specific product. When they tried to use the same conveyor for a lighter ingredient, they found that the rate was very low because the filter on the conveyor was blinded quickly. They wanted a conveyor that can transfer product efficiently without waste and at maximum capacity for all the powders.

Quadro Vac Solution

Quadro provided a pharmaceutical grade Quadro Vac pneumatic conveyor, equipped with a dry running, variable speed vacuum pump. When the speed of the pump is varied, the volumetric air flow rate also varies, allowing the conveyor to be used with multiple products. For a higher bulk density, when a higher pick-up velocity is required, the pump speed can be turned up. For lower bulk density products, the pump speed can be turned down to ensure optimum conveying without filter blinding. Hose sizes can remain the same.

The unit was also equipped with Quadro's own computerized User Interface that allows for pre-programming of the cycle times and pump speeds for multiple products. Each product code is tagged to a unique set of running parameters.

When the operator needs to change over from one product to the next, he/she simply enters the product code on the container label and the Quadro Vac automatically adjusts the timers and pump speeds to allow for optimum conveying of the particular product.

  

Summary

The customer's requirement for one conveyor for all products at maximum rate was achieved. The customer subsequently purchased 7 more units, complete with computerized User Interface controls and floor to ceiling height adjustable hoists for all their suites.
