Scraper Blade with Baffle Agitation Systems

Used in conjunction with cone bottom tanks on products of a very viscous and tenacious nature
Scraper blades remove product film from side and cone surfaces greatly enhancing the heat transfer
Mild agitation of the product is enhanced by the fixed baffle which also provides a blending and gentle folding action
Products best suited for this type of agitation include:

pet food
pumpkin mix
gravies
bakery sponge
heavy creams
Agitator maximum speed is 20 rpm, available with single or two-speed drives ranging from 1 to 7-1/2 hp.

Heavy Products Scraper Blade Agitation Systems

Used in conjunction with cone bottom tanks for gentle intermixing and solid suspension of heavy products
Scraper blades afford the maximum heat transfer
Twin baffles provide gentle folding, shearing and blending action
Primarily used in blending viscous and tenacious products
Products best suited for this type of agitation include:

heavy syrups
pet food
pie fillings
cheese spreads
Agitator maximum speed is approximately 35 rpm, and is available in single, two, or variable speed drives ranging from 1 to 7-1/2 hp.

Vertical Bar Heavy Product Scraper Blade Agitation Systems

Used in conjunction with cone bottom tanks for gentle intermixing and solid suspension of heavy products
Scraper blades afford the maximum heat transfer
Vertical bars provide a gentle folding of product
Primarily used in blending viscous products
Products best suited for this type of agitation include:

syrups
milk products
creams, macaroni and cheese

Scraper Blade/Squirrel Cage Combination Agitation Systems

Used for products that require both high-speed mixing and thorough gentle blending during the cooking and/or cooling function
Dual agitation is provided to achieve maximum performance
High-speed squirrel cage agitator is used for the rapid dispersal and incorporation of ingredients into the product
Scraper blade agitator operating at low rpm moves the product over the heat exchange surface while continuing the blending action
Slow gentle agitation assists in keeping the ingredients in suspension
Combination agitator speeds would be identical to the standard scraper blade and squirrel cage when used separately
Counter Rotating Scraper Blade Agitation Systems
