In the food and beverage industry, the filtration process is crucial for ensuring product quality and safety. The importance of food and beverage filtration is reflected in the following aspects: Improving Product Quality: Filtration can remove impurities and particulates from food and beverages, thereby enhancing the purity and taste of the products, ensuring that consumers receive high-quality products. Extending Shelf Life: By removing microorganisms and spores through filtration, the risk of product spoilage and deterioration can be reduced, extending the shelf life of food and beverages. Meeting Regulatory Requirements: Many countries and regions have strict food safety regulations that require food and beverages to meet certain hygiene standards during production. Filtration is an important step in meeting these regulatory requirements. Protecting Production Equipment: Filtration can prevent large particulates from entering production equipment, reducing wear and breakdowns, and extending the service life of the equipment. Increasing Production Efficiency: Filtration can reduce downtime during production because the need for cleaning and maintenance is reduced, thereby increasing overall production efficiency. Ensuring Food Safety: Filtration is one of the key components of food safety management and can effectively remove bacteria, viruses, and other harmful substances that may cause food poisoning. Improving Product Appearance: Filtration can remove suspended solids and sediments that affect the appearance of products, making them look clearer and more visually appealing. Reducing Waste: Effective filtration can reduce the number of non-conforming products, minimizing the waste of raw materials and energy. Adapting to Market Demand: As consumer demand for healthy and natural products increases, filtration technology can help manufacturers provide purer products with fewer additives, meeting market demand. Supporting Sustainable Development: By reducing waste and improving resource utilization efficiency, filtration contributes to the sustainable development of the food and beverage industry.

Bottled Water plus-circle minus-circle

Challenges in bottled water filtration:

With the intensification of environmental pollution, the quality of source water may change significantly, presenting challenges to filtration processes that require continuous adjustment of filtration plans to adapt to changes in water quality. Microbial control in bottled water is a key challenge in the filtration process, necessitating effective removal of bacteria, viruses, and other microorganisms to ensure the safety of water quality. Bottled water filtration requires the removal of particulate impurities from water, such as silt and minerals, to improve the transparency and taste of the water. Choosing the right filtration materials to meet requirements for filtration accuracy, flow rate, service life, etc., while considering cost and replacement frequency. Improving filtration efficiency while ensuring filtration effects and reducing operating costs is an important issue faced by bottled water filtration. Ensuring consistency in taste, color, microbial content, etc., across different batches of bottled water poses higher demands on filtration processes. Additionally, regulations and standards for bottled water vary by country, and companies need to continuously adapt to and comply with regulatory requirements in different markets.

Beverages plus-circle minus-circle

Challenges in Beverage Filtration:

The market features a variety of beverages, including soft drinks, tea beverages, plant-based protein beverages, etc., each with distinct filtration requirements. The filtration of carbonated beverages often employs microporous membranes and activated carbon to eliminate suspended particles, sediment, and microorganisms. For juices and tea drinks, it is necessary to remove fruit pulp or residue to prevent downstream filter blockages by solids. Microbial control during the production process is also of utmost importance; beverages can contain a multitude of microorganisms such as bacteria, yeasts, molds, and viruses, which must be completely removed to ensure compliance with microbial safety standards.

SANITEK Filtration Solutions for Beverage :

SANITEK offers a comprehensive filtration solution for beverages, which includes diatomaceous earth pre-filtration to eliminate larger particles such as fruit skins, pulps, or tea leaf fragments from the raw materials; the use of deep filtration media to remove finer particles and suspended solids; and the application of microfiltration technology to remove microorganisms, spores, and smaller particles from the beverages, ensuring their microbial safety.

Fermented Alcoholic Beverages plus-circle minus-circle

Challenges in Alcoholic Beverage Filtration:

Alcoholic beverages can be categorized based on various criteria, including fermented types such as beer, wine, and distilled spirits; blended types, and spirits, etc. The quality of water is of utmost importance in the production of alcoholic beverages. Poor quality water used for dilution, or water with high levels of metal salts, can lead to cloudiness and sedimentation when incorporated into the beverage. Hence, filtration of water in the alcoholic beverage production process is essential.

Dairy Products plus-circle minus-circle

Challenges in Dairy Filtration:

The challenges encountered during the filtration of dairy products primarily include:

Filtration of dairy products is a crucial step in dairy manufacturing, aiding in enhancing product quality, prolonging shelf life, and refining taste. Common dairy products include fresh milk, pasteurized milk, yogurt, and cheese products, among others.

Dairy products consist of complex components; milk contains a multitude of substances such as fats, proteins, lactose, minerals, etc. The varying sizes and properties of these components necessitate precise control during the filtration process to ensure product quality.

Stringent microbial control is required for dairy products. Raw milk contains a variety of microorganisms, including bacteria and spores, which must be eliminated through filtration or subsequent pasteurization to guarantee product safety.

Filtration of dairy products may lead to membrane fouling due to the deposition of components like proteins and fats, necessitating regular cleaning and filter membrane replacement. In the production of products such as cheese, milk must be concentrated to enhance yield and quality, demanding filtration techniques capable of effective component concentration and standardization.

Lenticular Filter

Lenticular filters are commonly used in the food and beverage industry for their multi-layered stacked filtering media to remove impurities from liquids. This technology is widely applied in the fields of fine chemicals, pharmaceuticals, cosmetics, food and beverages, and biotechnology for liquid filtration. Lenticular filtration can effectively remove particles, colloids, microbes, and organic impurities from liquids, achieving the goals of decolorization, removing unwanted by-products, or correcting taste and odor.

SANITEK offers two efficient lenticular filters: the positively charged diatomaceous earth DIEdisc® I and the activated carbon ACCdisc® I. The filtering material of the lenticular filter is formed by high-temperature curing of wood cellulose, diatomaceous earth or activated carbon, and wet-strength resin, and then by grafting the functional groups carried by the charged polymer substances onto the surface of the base material to form a stable chemical bond, thus endowing the deep filtration material with the electrostatic capture capability of a positive charge. Through electrostatic adsorption, it can effectively adsorb negatively charged microbes, endotoxins, and cell debris, and is widely used in the pre-filtration of the food and beverage industry.

Membrane Filtration

Membrane filtration is a physical separation process that utilizes a semipermeable membrane as a medium to separate different components of a mixture based on molecular size, shape, or other characteristics. This technology is widely applied in various fields such as water treatment, food processing, biopharmaceuticals, and purification of chemical products. In the food and beverage industry, it is essential to remove spoilage microorganisms from beverages or wines by 100%, including unwanted yeasts, E. coli, and other bacteria. These membrane filters are typically used in the final filtration stage and are installed directly upstream of the filling equipment.
