    Who Needs Yinuo vacuum filter?

    Vacuum drum filters are widely used in the food industry. They are applied in solid-liquid separation and purification during starch sugar and glucose production, clarification filtration of fruit juices, impurity removal in beer brewing, and filtration purification of soy sauce and vinegar. Combined with diatomaceous earth filtration technology, they can enhance product purity and efficiently meet the cleaning and separation needs of various processes.

    • Starch factories: In starch production processes, it is necessary to dewater starch slurries. For instance, potato starch, wheat starch, and other starches have high moisture content after extraction. Using a vacuum drum filter enables continuous suction filtration, washing, and dewatering, thereby yielding starch products that meet production requirements.
    • Starch sugar factories: When producing starch sugars such as crystalline glucose, xylose, and xylitol, pre-coating filter aids and using a vacuum drum filter for continuous suction filtration, washing, and dewatering ensures product quality. Additionally, its horizontal installation and cooling crystallization functions contribute to uniform particle size of the produced starch sugars.
    • Food additive factories: In the production of food additives, vacuum drum filters are used when solid-liquid separation is involved and high clarity of the filtrate is required. For example, in the production of certain colloidal food additives, they can effectively separate impurities and improve product purity.
    • Breweries (involving yeast production processes): During yeast production, it is necessary to separate yeast cells from the fermentation broth. Vacuum drum filters enable continuous solid-liquid separation: the vacuum suction draws the liquid through the filter medium, leaving the yeast cells behind, which meets the production requirements.

    The vacuum drum filter is an efficient solid-liquid separation equipment in mining and metallurgical plants. It can dewater the ore slurry after beneficiation of gold, nickel and other ores to facilitate subsequent smelting. It can also handle red mud in alumina plants, wash and dewater aluminum hydroxide suspensions, realizing resource recovery and waste residue treatment, and improving the quality and efficiency of metallurgical production.

    • Metal Ore Processing Plants: In the beneficiation process of metal ores such as gold, nickel, and cobalt ores, after processes like flotation and gravity separation, ore slurries containing metallic minerals are obtained. Vacuum drum filters can be used for dewatering these slurries, facilitating subsequent smelting and processing.
    • Alumina Plants: During alumina production, large amounts of red mud (a type of waste residue) and suspensions containing aluminum hydroxide are generated. Vacuum drum filters can be used for the filtration and separation of red mud, as well as the washing and dewatering of aluminum hydroxide suspensions, enabling resource recovery and waste residue treatment.

    In the sewage treatment process, a large amount of sludge is generated. Vacuum drum filters can dewater the sludge, reducing its moisture content and volume, which facilitates subsequent sludge disposal such as landfilling, incineration, or resource recycling.

    • They are primarily used for dewatering sludge generated during wastewater treatment, reducing sludge moisture content and volume to facilitate subsequent disposal (e.g., landfilling, incineration) or resource utilization (such as producing fertilizer or fuel).
    • They can also treat specific industrial wastewater slurries, separating solid impurities from liquid streams to purify wastewater and meet discharge standards.
    • In some cases, they assist in the filtration and recovery of valuable substances from wastewater, enhancing the efficiency of resource recycling in treatment processes.
