Agitators for Dairy & Milk Processing Tanks

Premix Technologies manufactures hygienic top-entry agitators for dairy and milk processing tanks used in milk storage, standardization, cream blending, ingredient dispersion and recombination duties. Engineered for sanitary operation, these agitators deliver gentle, uniform mixing that protects product quality while keeping milk, cream and added ingredients homogeneous throughout the batch.

Mixing Requirements in Dairy Processing

Dairy processing places specific demands on agitation. Mixing must be thorough enough to keep fat, solids and added ingredients uniformly distributed, yet gentle enough to avoid excessive shear that can damage fat globules or incorporate air. Equipment must also meet sanitary standards — smooth contact surfaces, crevice-free welds and easy cleaning to support CIP routines and prevent product contamination. Temperature uniformity matters too, since dairy tanks are frequently heated or cooled during processing.

Typical dairy mixing duties include milk storage and standardization, cream and fat blending, dissolving and dispersing vitamins, minerals and stabilizers, alkali (KOH) and cleaning solution circulation, and sub-batch preparation in recombination plants.

Premix Engineering Approach

Each dairy agitator is sized for its specific tank and duty rather than supplied as a generic unit. Selection considers tank volume and geometry, the product being mixed, required blend time, viscosity, sensitivity to shear and heat-transfer needs. Typical engineering features for dairy applications include:

• Hydrofoil and pitched-blade-turbine (PBT) impellers — efficient, gentle flow for low-shear blending of milk and cream.
• Anchor impellers — for higher-viscosity products and improved heat transfer near the tank wall.
• Sanitary SS 316 contact parts — smooth finishes and hygienic construction suited to food-grade duty and cleaning.
• Sealing options — mechanical seals appropriate to hygienic and closed-tank operation.
• Specific-power sizing — motor and gearbox matched to the blend duty (kW/m³ by duty type) to avoid over-agitation.

Impeller Selection by Duty

The right impeller depends on what is being mixed. Low-viscosity milk storage and standardization tanks use high-efficiency hydrofoil impellers for gentle bulk movement. Cream and ingredient blending may use pitched-blade turbines for combined flow and mild shear. Viscous or heat-transfer duties — such as concentrated mixes near a jacketed wall — benefit from anchor impellers. Premix selects and combines these based on the actual product and tank.

Representative Specifications

• Tank capacity: from small batch tanks to large milk storage and process tanks
• Impeller types: hydrofoil, pitched-blade turbine (PBT), anchor
• Contact MOC: SS 316 (food-grade), sanitary finish
• Mounting: top-entry, with gearbox and drive sized to duty
• Sealing: hygienic mechanical seal options

Exact impeller diameter, motor power, RPM and seal type are determined from the specific tank and product for each enquiry.
