Votator’s high efficiency and
productivity results from a simple
concept, heat or cool continuously
moving product by providing a large
heat transfer surface for a small
amount of product in a confined
space.
Inside every Votator
®
, a mutator
shaft rotates within a tube. The
product passes through an annulus
formed by the shaft and heat transfer
tube (light yellow). Heating or
cooling medium flows in a jacket
(orange). The unit is insulated (pink)
to minimize energy loss and protect
personnel. A stainless steel cover
protects the insulation.
In operation, the rotating shaft has
blades which continuously scrape
product film from the heat transfer
tube wall, thereby enhancing heat
transfer, and agitating the product to
produce a homogenous mixture.
Concentric
For most applications the shaft is mounted in the
center of the heat transfer tube, or CONCENTRIC.
Eccentric
An off centered shaft mount or ECCENTRIC design
is recommended for viscous and sticky products.
This shaft arrangement increases product mixing,
eliminates mass rotation, and reduces the
mechanical heat load.
Oval Tubes
Oval tubes are used to process extremely viscous
products. This design eliminates product
channeling within the tube, it reduces mechanical
heat by a double cam action of the scraper blades,
and it balances the internal forces to prevent shaft
deflection.
