China Milk vacuum filter manufacturer-Xinxiang Yinuo Machineries Co., Ltd.

Milk vacuum filter

The milk vacuum filter is a sanitary-grade solid-liquid separation device specifically designed for the dairy industry. Utilizing vacuum suction principles and a rotating disc structure, it enables continuous, integrated, and highly efficient filtration, washing, and drying of dairy materials such as milk and whey. It is widely applied in key processing stages within the dairy sector, including raw material impurity removal, whey separation, and efficient recovery of milk proteins.

Product Introduction

The core of the milk filter consists of multiple parallel filter discs, each divided into several sector-shaped filter plates. During operation, the disc section is submerged in the liquid tank and connected to the vacuum system via a distribution head. Vacuum suction draws the filtrate through the filter cloth into internal channels, while solid particles are retained on the filter cloth surface to form a filter cake. As the discs rotate, the filter cake sequentially passes through the filtration zone, washing zone, drying zone, and discharge zone, completing the entire filtration cycle. All parts in contact with the material are constructed from food-grade 304/316L stainless steel. Surfaces undergo polishing treatment, ensuring no dead corners and easy cleaning, meeting product hygiene and safety requirements.

Selection Recommendations:

Based on Processing Capacity:

· Small dairy plants: Models with a filtration area of 5-15 m² are suitable. For large-scale dairy processing enterprises, equipment with a filtration area of 20-50 m² is recommended to meet continuous, large-scale production demands.

Based on Material Characteristics:

· Skim milk/whey: Higher vacuum levels and smaller pore size filter cloths are recommended to ensure effective clarification and separation.

· Fat-containing materials:Moderately reduce vacuum pressure to prevent fat globule rupture under high pressure differentials, thereby preserving final product flavor and quality.

Supporting Systems:

· To enhance operational stability and overall efficiency, integrate a CIP (Clean-in-Place) system, vacuum buffer tank, and filtrate recovery unit. This configuration minimizes downtime, maximizes equipment utilization, and further safeguards product quality.

Applications of Milk vacuum filter:

Milk Clarification: Removes dust, impurities, microorganisms, and colloidal particles from raw milk, enhancing the purity and physical stability of dairy products while reducing wear on downstream processing equipment.

Whey Processing:

· Separates residual casein particles, free fat globules, and other suspended solids from whey, ensuring high-quality whey powder production;

· Efficient recovery of whey protein to enhance raw material utilization and product value;

· Also removes lactose crystals to optimize product texture and solubility.

Cheese Production: During cheese processing, separates curds from whey to improve yield and quality.

Milk Protein Concentration: Concentrates milk proteins through selective filtration to produce high-protein dairy products.

Other Dairy Applications: Widely used in pre-treatment and refining processes for yogurt, cream, butter, and other products. Effectively removes impurities introduced or generated during processing, ensuring product sensory and hygienic quality.

Milk vacuum filters have become one of the key pieces of equipment in modern dairy processing due to their advantages of efficient separation, hygienic reliability, and flexible operation. They effectively help enterprises enhance product quality, reduce production costs, and strengthen overall market competitiveness.
