Industrial raisin washing system
Achieve thorough cleaning and separation for small, high-density food products with this innovative washing system, designed to maximize particle removal and enhance product outfeed efficiency in continuous processing operations.

Washes, Disinfects, and Separates Dried Fruits and Vegetables
The GEWA 3850T PLUS from KRONEN GmbH is a comprehensive washing system tailored for high-density dried fruits and vegetables. Utilizing a helical washing system, it ensures thorough cleaning through a spiral motion in the wash tank. This design enables effective pre-cleaning, washing, disinfection, and rinsing in a continuous automatic process, making it ideal for processing operations with demanding purity requirements.
The machine specializes in handling products such as raisins, apricots, and salad components, ensuring efficient removal of fine particles and foreign materials. It integrates seamlessly into production lines, offering a throughput of up to 800 kg/h, thereby solving high-volume processing challenges.
Equipped with advanced features like pre-vibration for sand and particle separation, lateral fine particle removal drums, and sand trap sedimentation units, the GEWA 3850T PLUS minimizes water usage while maximizing cleaning efficacy. Constructed from AISI 304 stainless steel, it is designed for durability and easy maintenance, with all components accessible for cleaning.
This machine supports PLC-controlled functions, facilitating minimal manual intervention and efficient operation. Its versatility extends to applications across food processing industries, whether for dried fruit manufacturers or salad processors, providing a hygienic and efficient solution aligned with best practices and industry standards.
