Used primarily for blending of low viscosity products, impeller style agitators such as Pitched Blade Turbines, Marine Props and High Efficiency Axial Flow impellers are the most common tank agitators. This very versatile agitator may be used in conjunction with baffles, single or multiple impellers that can be adjustable or fixed in location and operating at a variety of speeds to match the shear and pumping characteristics required for the application. Typical applications include blending low viscosity liquids across all industries.

Traditional, familiar turbine designs
High efficiency axial flow “Hydrofoil” impellers
High solidity ratio “Marine” style props
Vertical / Radial blade turbines
Custom / specialized impeller designs
Welded or adjustable design
Sanitary CIP-able in-tank bottom support guide is standard
Free-hanging, unsupported options are available

These low speed agitators are perfect for enhancing heat transfer while providing good overall flow in an agitator that is gentle to your product. These agitators are suitable for viscosities up to 10,000 cps. By sweeping over the vessel surface without scraping or pumping it, products such soups, yogurts and creams can be properly agitated but not damaged.

Sweep bottom head and sidewall
Blades do not contact tank
Improved heat transfer
Flow from perimeter to core
Suited for viscosities to 10,000 cps
Low shear

Heat Transfer expectations often require the use of a scrape surface agitator. By scraping the vessel surface, heating and cooling times can be cut in half while preventing product burn on. Due to their relatively low speed, Scraper agitators move the project with very little shear or air entrapment. Typical applications include Juice concentrate tanks, sour cream & cream cheese mixing, and cosmetic applications. Feldmeier has designed the most cleanable method of Scraper attachment in the industry, designed without the use of clips, pins, snap rings or o-rings, typical cleaning concerns are minimized.

Scraper blades on the bottom head and sidewall
Plastic blades contact the tank wall to minimize stagnant product on the surface
Improved heat transfer
FDA plastic blades available in UHMW, Nylon, PTFE Teflon, and more
Moderate to High viscosity applications
Low shear

For the most demanding applications, multiple agitators are often required in a single vessel. Centered on our “Thermo-mixer,” Feldmeier manufactures a complete line of multi-agitated vessels. By adding a Turbine agitator that opposes a Scraper, the benefits of high product turns and scrape surface can be combined. This versatile agitation system is typically used for products such as shampoos and body washes. For applications such as creams, lotions and toothpaste a high shear homogenizer can be added as well. When it comes to Counter-Rotating & Triple Agitated vessels Feldmeier is the leader in the industry manufacturing sizes ranging from 15 – 8,000 gallons each year.

Maximize heating / cooling capability
High viscosity products
Scraper blades on the bottom head and sidewall
Plastic blades contact the tank wall to minimize stagnant product on the surface
FDA plastic blades available in UHMW, Nylon, PTFE Teflon, and more

For high shear applications, Feldmeier Equipment’s bottom entering “RapidMixer” agitator is tough to beat. By locating the impeller at the low point of the liquid, solids and semi-solids are naturally drawn into the agitator for fast, efficient dissolving. Typically belt driven for easy maintenance and service, this mixer feature a heavy-duty impeller which sustains a constant circulation within the vessel for uniform mixing maximum exposure of product to heat transfer surface.

Sizes from 25 hp to 100 hp for batches up to 600 gallons
Offset belt driven are standard; direct drives are available as an option
USDA-MID approved
Agitator may be installed in single shell or insulated & jacketed vessels both cylindrical and square

Feldmeier’s Horizontal CIP-able Agitator is USDA accepted and designed for use in 3-A Silos and Storage Tanks. The patented design features sanitary internal construction to ensure effective CIP that does not require user adjustment. It is the simplest design in the industry with (1) moving part making it easy to disassemble and easy to install in new or existing vessels. Feldmeier’s standard design is suitable for milk, skim milk, cream, half & half, infant formula, and beverage applications. By standardizing on an oversized prop compared to our competitor’s option, we can more effectively agitate product at low speeds to minimize foaming.
