Tunnel Washers
Tunnel Washers for the Bio-Pharm 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. San-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:
Injectable Liquids/Potent Compounds/API’s/Solid Dosage/ Creams/Lotions/OTC’s

Tunnel Washer Equipment cleaned:
IBC Bins/Totes/Trays/Bulk Containers/Product Carriers/ Pallets

Tunnel Washers - How It Works

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 for heavy product residues.

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 and overflows to Pre-Rinse (PR) if present.
4. The Fresh Water Rinse (FR)removes the remaining detergent film and overflows to Recirculated Rinse (RR) to conserve water.

Pallet Washer & Material Handling
Pallet Washers for the Bio-Pharm Industry

Sani-Matic Pallet Washers improve quality control and sanitary product handling. Available in either horizontal or vertical design, the Pallet Washer operates similar to the Tunnel Washer with the same standard features and options. Sani-Matic Pallet Washer Integrated Material Handling may be added to provide synchronized stacking and de-stacking of pallets to maximize cleaning and handling efficiencies.
