Conveyor cleaning and cooling system for pasta
Efficiently halt cooking processes and eliminate surface starch with a streamlined system that cools products swiftly, retaining quality and freshness for subsequent processing stages.

Cools, Washes, and Removes Starch from Products
The WZ Washing Zone from GEA is a purpose-built conveyor system designed to enhance the quality of pasta and cereal production by cooling, washing, and removing starch from products such as chilled penne, blanched macaroni, and cooled snack pellets. This machine’s specialized conveying mechanism features an inclined belt with a plastic material, optimizing continuous automated processes for productive, low-maintenance operations. The WZ includes a divided bottom water tank for effective water recycling, reducing consumption while maintaining product temperatures as low as 25°C. Top spraying ramps controlled via flow switch and regulating valve ensure thorough coverage and starch elimination. Constructed with stainless steel, it guarantees durability and ease of cleaning through accessible hinged covers, meeting the stringent hygiene standards required in food processing environments. With belt widths ranging from 750 to 1200 mm and a washing length of 2.5 m, the WZ readily integrates into any existing line, suited to food processing companies seeking reliable and efficient starch removal systems.
