The food industry uses industrial filtration in some production processes. This stage is used to ensure the quality and safety of food products, a priority for manufacturers, consumers, and regulatory agencies. Filtration helps ensure the quality and safety of food by removing impurities and unwanted particles that can affect the appearance, taste, and safety of food.
How can vertical hermetic leaf filters help in the food industry?
Hollbras produces hermetically sealed vertical leaf filters (HBV) that perform mechanical filtration. In this process, solids suspended in liquids are separated using filtration leaves coated with different types of filter elements (precoat). Mechanical filtration is commonly used to remove suspended particles such as solids, impurities, and contaminants, guaranteeing the quality of the end product. For example, filtration can be used to clarify liquids such as juices, vegetable oils, wines, and beers, removing solid particles that affect appearance and taste.
How do Hollbras HBV vertical leaf filters work?
Vertical leaf filters consist of several filtration leaves positioned in a vertical vessel operating under pressure. The process begins with the formation of a pre-coat. This pre-coat can be made up of the solid to be filtered or filter aids. The material to be filtered is then pumped into the filter under pressure, forcing it through the filtration leaves lined with their pre-coats. During this process, the solid particles are retained while the filtrate flows into the leaves, passing through the collecting tube and being directed to a filtrate tank. The process ends when the filter reaches its maximum solids limit. At this point, the filter is drained, and the retained solids are dried for dry discharge by vibration or washed when the option is wet discharge.
Quais são as aplicações dos filtros HBV na indústria alimentícia?
Vertical leaf filters are used in various applications in the food sector, such as:
What are the benefits of Hollbras vertical leaf filters for the food industry?
