Agitators
Agitators : An agitator is an apparatus for shaking or stirring.
Agitators vary in relation to individual process conditions, product characteristics and the degree of agitation required to achieve the desired end product.
Some of the basic types of Agitators include: -
Side and Bottom Scrape Agitator-Designed to ensure complete scraping of sidewall and bottom eliminating product burn-on or freeze-on. Increases heat transfer efficiency by moving product across the heat transfer surface sidewall and bottom.
Side and Bottom Sweep - An anchor type agitator consisting of bottom and side blades providing close clearance to the sidewall while promoting rapid heat transfer and reducing localized burn-on or freeze-on.
Bottom Sweep Agitator - Consisting of large diameter paddle sweeping across the tank bottom, lifting the product and pushing it ahead with a horizontal and vertical mixing action. Ensures thorough mixing and aids in unloading product.
Side Scrape and Bottom Sweep Agitator -The agitation system combines a low level sweep paddle with a circumferential scraper. The cupped bottom blade ensures a homogenous product mix and an even temperature distribution while scrapers continually expose new product to the sidewall, providing rapid heat transfer and eliminating film buildups which might burn or freeze on the sidewall surface.
Vertical Offset Agitator - These agitation systems incorporate multiple paddles or turbines in an off-center tank mounting. This configuration eliminates the need for baffles and guarantees thorough top-to-bottom pumping of product, producing complete movement of the entire body of the product in your tank. This application system is ideal for applications in a tank with a height to diameter ratio greater than one to one.
Side Entering Agitator - Consists of a direct drive horizontal propeller which provides thorough bottom to top pumping of product. This provides a gentle mixing of light and medium bodied products, assures good heat transfer, and ensures an adequate blending of liquids.
Dual Motion Agitator - Provides fast efficient blending and heat transfer through the combination of slow speed scraper and a higher speed turbine assembly, rotating opposite each other. Designed to ensure complete movement of viscous product in the tank, not just in the area of the impeller.
Ribbon Blender - Triple action agitation ensures thorough blending and mixing with capacities from 13 to 106 cubic feet. Product is moved simultaneously in opposite directions while the mixing action of the ribbon moves the product across the heat transfer surface completing the blending or heat transfer process. Portable Mixer- Utilizing single or dual, high-flow propellers driven directly or through a 5:1 gear box, these mixers are applicable to a wide range of products and tank volumes. The universal clamp mounting makes them ideal for most simple open tank mixing problems.
