Otokomae Tofu Inc.

Otokomae Tofu Inc. produces tofu (soybean curd) and is probably one of the most famous tofu producers in Japan. They have installed the second VOLUTE™ Dewatering Press in their Kiyosato factory, following the first one installed in their Kyoto factory. We interviewed the chief operator of their wastewater treatment plant to ask the reason why they have become our repeater.

They were using a belt filter press. When the company was considering installing sludge dewatering equipment in Kiyosato factory, the chief operator recommended that they install VOLUTE™ as well as the Kyoto factory, explaining,

“The reason why we installed the VOLUTE™ Dewatering Press again is its easy maintenance. In the case of a belt press, we had to clean it up every day, every after we stopped operation. If we left dry sludge in the equipment, cake solids content would be lower. To make it worse, we had to operate the equipment 20 hours per day, with lower cake solids content. On the other hand, the VOLUTE™ Dewatering Press takes only 15 minutes per week in summer and 30 minutes even in winter to maintain it. The operation is stable, and operation time is only 8 hours per day. Simple and effective.”
