Tunnel Washers
Tunnel Washers for the Food & Beverage Industry

Sani-Matic Tunnel Washers provide consistent, repeatable cleaning results for a variety of items. The basic design provides detergent and final rinse zones. Pre-rinse and recirculated rinse zones may be added for heavy product residues or high capacity requirements. Sani-Matic Tunnel washers are simple and efficient to reduce labor costs, minimize chemical usage, and lower water and utility costs while providing you with cleaning confidence.

Tunnel Washer Applications include:
Dairy/Beverage/Brewery/Bakery/Confectionary/Distilleries/ Meat & Poultry/Snack Foods/Sauces/Slurries

Tunnel Washer Equipment cleaned:
Pallets/Freezer Spacers/Slip Sheets/Distribution Trays/ Totes/Buckets/Barrels/Molds

Tunnel Washers - How They Work
Tunnel Washers for the Food & Beverage Industry

General Tunnel Washer Operation

Three section Tunnel Washers (detergent wash, recirculated rinse and final rinse) are the most commonly requested designs, however, the use of a pre-rinse section may be required depending on product residues, sanitation requirements, and desired throughput rate.

Operational overview of a 4-section washer:

1. Soiled product containers are conveyed through the Pre-Rinse (PR) section to loosen and flush off heavy particulates.
2. The Detergent Wash (DW) section loosens and sprays off the remaining product residue.
3. The Recirculated Rinse (RR) removes most of the residual detergent solutions from the product containers.
4. The Fresh Water Rinse removes the remaining detergent film.

Note: Final Rinse (FR) water overflows into Recirculated Rinse (RR) and then overflows into Pre-Rinse (PR) to conserve water.
