Wiegers Process Innovations B.V.

Description
The WPI Depositor is unique and a far cry from 20th century piston technology. It has been designed to deposit a range of products and works with either, indexing or continuous running lines.

Unlike conventional depositors, The Wiegers PDP system does not work with an open hopper but utilises a closed common rail (manifold) with a servo driven progressing cavity metering pump feeding each nozzle.

The common manifold is kept under constant pressure by a feeding pump, mounted below a buffer tank. This tank is jacketed and fitted with a slow rotating anchor type stirrer, which ensures that all the product remains homogenised at all times, thus eliminating the risk of product staling, as will occur in an open hopper as used in conventional systems. Neither is there risk of skinning, which happens if product is held in a hopper for a period of time.

The product in the common manifold that feeds the nozzles on the WPI, is held under constant pressure, which ensures extremely accurate depositing across the width of the conveyor regardless of the number of nozzles in operation at any given time.

Description
The TempAerator is a vertically scraped surface heat exchanger, with two concentric heat exchange surfaces providing optimum heat transfer, combined with a continuous aeration head. 

The WPI TempAerator has been granted with an Innovation award. 
The scraped surfaces provide a continuous cooling / heating process combined with gentle product handling.

Description
Temperature control is essential to guarantee a good production process. WPI designs and builds temperature control systems suitable to regulate each part of a process. The water tempering system has an integrated water chiller, and water heating system. Multiple circuits can be installed to control each step in your production process independently, with an accuracy of 0.1°C. Our water tempering systems are executed with a heat recovery system in the chiller to, save energy on heating.
