Agitator Type ALB

Alfa Laval Type ALB -
Bottom-Mounted Agitator

Alfa Laval Bottom-Mounted Agitators come in a range of sizes and designs, and is suitable for mixing applications in Food, Dairy, Beverage, Pharmaceutical, Biotechnology and Cosmetic industries.

ALB Agitators can be used in both atmospheric and pressurised vessels, with a range of size options making them suitable for a wide spread of tank volumes, allowing for optimal power consumption. The modular design and choice of size ensures an Agitator fit-for-purpose, so you can minimise investment outlay while maximising efficiency. ALB Agitators are designed for easy CIP and can also be configured for use in sterile/aseptic applications, and environments with potentially explosive atmospheres.

How the Type ALB Bottom Mounted Agitator Works

The Alfa Laval ALB Agitator is a Bottom Mounted Agitator, suitable for tank mixing in a wide range of Food, Dairy, Beverage, Distilling, Pharmaceutical, Biotechnology or Personal Care applications.

The ALB Agitator has an electrical drive motor that rotates the Agitator shaft, either directly or via a gearbox. This turns the EnSaFoil impellers, whose movement creates a high flow, low shear axial pumping effect on the liquid in the tank. The result is effective mixing and blending of the entire contents.

Duties Typical Examples
Maintaining mixture homogeneity Milk storage tanks, cream tanks, mixed product tanks, UHT, and product storage tanks
Mixing suspensions and solutions Fluid and fluid mixing, drinking yoghurt and fruit mix tanks, flavoured milk mix tanks, and syrup mix tanks
Dispersing Powder protein and oil mix tanks, micro salt and milk product mix tanks
Suspension Fluids with particles, juice tanks, crystallizing tanks, etc.
Heat transmission Circulation of media in tank with dimple jacket (cooling or heating)
Flocculation Wastewater treatment tanks
Operation features Due to
Low energy consumption The wide range of high efficiency propellers and drive units makes it possible to design for low operational costs
Gentle product treatment The wide range of high efficiency propellers makes it possible to design for low shear operation
Hygienic features Due to
Easy external cleaning Stainless steel bearing frame design with seal O-rings (for washing)
Connections inside the tank (risk zones) can be minimised Bearing frame drives with drive shaft and special internal shaft connection without having a flange coupling inside the tank
Good drip off properties No plane surfaces or grooves on internal parts
Easy CIP No interior shadow sides between the blades and smooth surfaces
Maintenance features Due to
All servicing (replacement of wearing parts such as shaft seals, bearings, etc.) can be done from outside the tank Bearing frame drives with detachable shaft which can be dismounted from outside the tank
Easy dismantling Use of spider type coupling and stainless steel parts

FAQs

The Alfa Laval ALB Agitator is a bottom-mounted Agitator, suitable for atmospheric and pressurised tanks.

The ALB bottom-mounted Agitator is designed for a wide range of tank mixing and blending duties across the dairy, food, beverage, brewery, personal care, biotechnology and pharmaceutical industries.

The Alfa Laval ALB Agitator meets both EU and US standards and regulations such as EHEDG, USDA, FDA and 3-A Sanitary Standards

The seal arrangements available for the ALB Agitator are:

  • F-S1 (Seal flange with O-ring seal against tank flange, drain, fluid trap and shaft seal: single mechanical bellow seal)
  • F-S2 (Seal flange with O-ring seal against tank flange, drain, fluid trap and shaft seal: single mechanical nonbellow seal)
  • LF-S1 (Lantern (spacer), seal flange with O-ring seal against tank flange, drain, fluid trap and shaft seal: single mechanical bellow seal)
  • LF-S2 (Lantern (spacer), seal flange with O-ring seal against tank flange, drain, fluid trap and shaft seal: single mechanical nonbellow seal)
    LF-D (Lantern (spacer), seal flange with O-ring seal against tank flange, drain, fluid trap and shaft seal: double mechanical seal for high pressure applications and aseptic use)

The range of high-efficiency drive units and EnSaFoil impellers make it possible to design the ALB Agitator for maximised energy efficiency.

Our team of mixing technology experts will be happy to advise you on the ideal Agitator type and configuration for your applications. We will need the following information to ensure we can properly specify your unit:

  • Tank geometry
  • Product properties
  • Task of Agitator

Alfa Laval EnSaFoil impellers can range from just 125mm in diameter to 1900mm, so the ALB can be used in almost any size of tank.
