Gianpiero Baldisserotto, Sales Director, MB Conveyors Srl, Italy

MB conveyors has developed a custom-made conveyor system as part of a large bottling plant from a big Italian OEM in the Food & Beverage industry.

This horizontal-motion conveyor can smoothly and efficiently move a huge variety of materials which in this case are plastic caps for a bottling line.

The conveyor’s task is not only to receive the caps from the injection or compression molder and transfer them from a point A to a point B, but also to cool them along the path.

Pfannenberg and MB Conveyors have studied and tested together the most appropriate solution.

The Customer

Since 1985 MB Conveyors designs and manufactures custom-made solutions, machinery and systems for every application and need in the field of industrial handling.

The company based near Vicenza, in North-Eastern Italy, is a well-known designer and manufacturer of made-in-Italy conveyor belts and auxiliary machinery that are today sold in over 60 countries worldwide, and widely recognized for their excellence in the field.

The PA standard flat conveyor equipped with an additional tunnel and a combination of chiller and air/water heat exchanger from Pfannenberg.

The Solution

With the goal of introducing a cooling component into the conveyor belt path, MB Conveyors had already created a small tunnel and first experimented the lower impact solution: cooling with filterfans. This type of solutions proved to be poorly adequate for this application needs.

To achieve higher cooling capacity the use of rooftop cooling units was considered. This approach turned out to be effective for cooling but involved risks related to the contaminated environment of the machines characterized by ambient air with high content of dust.

Pfannenberg therefore proposed the combination of a RACK 2400 chiller and a PWD 5302 air/water heat exchanger.

This solution was widely appreciated since it guarantees both an efficient cooling and an uncontaminated environment.
