VLS Technologies presents Lees-Stop, the new crossflow filter for must and lees. The Lees-Stop filter allows you to process lees, musts and solutions with a high content of suspended solids at high performance even in the presence of filtration adjuvants. The filtrate quality is much higher than that obtained with traditional filtration made by rotary drum vacuum filters. It can be used immediately without any additional treatment. The Lees-Stop allows you to obtain a high quality product by keeping its properties and alcohol gradation, unlike what happens with rotary drum vacuum filters.
