Conveyorized Tunnel Washer Process
The ideal tunnel washer for your company depends on the type of quantity of items to be washed, the type of soil to be removed, the desired wash time, heating and drying options, water and energy usage, space limitations, and budget considerations.
Conveyorized Tunnel Washer Features
Regardless of the model, each Douglas Machines’ conveyorized tunnel washer features:
- Our tunnel washers can be configured with any combination of 4 standard sections: recirculating wash, recirculating rinse, fresh sanitizing rinse, and blow-off.
- If needed, a recirculating pre-wash can also be added.
- Choose between vertical or horizontal load machines with either transport belts or chains depending on the shape of your containers
- We offer a single or two-lane operation with transport belts or chains to meet your desired throughput
- Machines can be designed for space-saving or water-saving and inline or off-line use.
Our computer-aided design and state-of-the-art manufacturing equipment allow us to produce customized tunnel washers with remarkable precision – without delay or added expense.
