SPRUWA washing machine

The SPRUWA is a spray washer for all types of root and tuber vegetables. It allows highly efficient cleaning and is available in various sizes and designs for potatoes and other field crop. The SPRUWA is designed as a self-supporting, sturdy sheet metal construction. In the potato version it is fitted with slanted metal-sheet bottom panels and a central outlet. The carrot version is fitted with a longitudinal opening as outlet as standard. The axis and spoke-free barrel is made of hot-dip galvanized steel and suspended from several V-belts from the two drive shafts running lengthwise to the machine. Each drive shaft is equipped with direct drive and a gear motor to reduce wear and tear.

Depending on the type of crop to be washed, the barrel is available in two designs. Barrels with round holes and turbulence paddles are used for potatoes. Barrels with elongated holes and turbulence fins are used for carrots, beetroot and celery. The edges of the holes are bent outwards for protection purposes to prevent the crop from coming into contact with sharp hole edges. This ensures maximum washing efficiency at optimal product protection. A spray pipe mounted lengthwise to the washer barrel allows washing with recycled process water or fresh water. A fresh water jet is installed at the outlet.
