Abstract: The present invention comprises methods and systems for manipulation of media and particles, whether inert materials or biomaterials, such as cells in suspension cell culture. The methods and systems comprise use of an apparatus comprising a rotating chamber wherein the actions of the combined forces of gravity, fluid flow force and centrifugal force form a fluidized bed within the rotating chamber.

Abstract: An ice cream machine for cooling liquid ice cream into frozen ice cream includes an evaporator system with a secondary evaporator. The evaporator system includes a cooling chamber having an ice cream input and an ice cream output. A valve can be placed at the ice cream input to achieve dry freeze operation. The valve can prevent the cooling chamber from being completely filled.

Abstract: A motor system can be provided for a tank for mixing and chilling ice cream. The motor system includes a variable speed motor having a speed control. The speed control can be utilized to operate the motor in a forward or reversed speed or across a spectrum of more than two forward speeds. The motor can drive an auger. The auger can be operated in reverse to add semi-solid or solid inclusions to ice cream mix. The inclusions can be added through an aperture at the output of the tank. Appropriate time for discharge can be determined by time, temperature, or amperage.
