微、細な食品屑が付着し水漏れを生ずるという重大な欠
点があった。However, with this type of system, high-pressure cleaning water or drainage water leaks from the vertical gaps that are inevitably created between the gate valve and the cleaning water and drainage passages, causing the cleaning water to leak during cleaning. Also, when draining water, water may leak through the gap between the switching valve and the casing, increasing the amount of remaining water, or fine food particles mixed in with the wastewater may adhere to the items being cleaned, causing water leakage. There were serious drawbacks to this.
