High thermal transfer, hollow core extrusion screws (50, 52, 124, 126, 190) include elongated hollow core shafts (54, 128, 130, 192) equipped with helical fighting (56, 132, 134, 194) along the lengths thereof. The fighting (132, 134, 194) may also be of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). Structure (88, 90) is provided for delivery of heat exchange media (e.g., steam) into the hollow core shafts (54, 128, 130, 192) and the hollow fighting (132, 134, 194). The fighting (56, 132, 134, 194) also includes a forward, reverse pitch section (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to be used as complemental pairs as a part of twin screw processing devices (20), and are designed to impart high levels of thermal energy into materials being processed in the devices (20), without adding additional moisture.

The present invention relates to a hand mixer having a heat activation function. The heat activation function preferably allows a user to heat ingredients that are to be mixed by a hand mixer. The hand mixer may include a cavity that has each of a fan, a motor to drive the fan, heated coils, and an output area or mouth. When a user wishes to activate the heating function to soften ingredients in a bowl or other vessel to be mixed, he or she may use a controller to activate the fan and blow air through the heated coils and out from the output area toward the ingredients to be mixed and/or mixing devices used to mix the ingredients, so that the ingredients may be softened.

A heating and stirring device is described herein that comprises a base configured to removably attach to one of a beverage container and a beverage container lid, the base containing a power supply, a controller, and a motor, and an agitator having a body and a length with a first end portion configured to be supported by the base, and a second end portion, wherein the first terminal end is configured to be outside of the beverage container and the second end portion is configured to be inside of the beverage container. Corresponding systems and methods also are disclosed.

An agitator rotor includes a shaft, rails, and a rod. The shaft defines a longitudinal axis. The rails extend radially from and are coupled to the shaft. The rails are separated from each other along a length of the shaft. Each rail includes a surface defining a non-zero angle with respect to the longitudinal axis of the shaft. The rod includes a first end coupled to a first one of the rails. The rod includes a second end coupled to a second one of the rails. A projection of the first end and the second end of the rod in a plane perpendicular to the longitudinal axis of the shaft defines a minor arc about a portion of the shaft.

A beverage mixing system/method allowing faster mixing/blending of frozen beverages is disclosed. The system/method in various embodiments utilizes inductive coupling to introduce heat into the frozen beverage during the mixing/blending process via a rotating driveshaft and attached mechanical agitator to speed the mixing/blending process. Exemplary embodiments may be configured to magnetically induce heat into the driveshaft and/or mechanical agitator mixing blade to affect this mixing/blending performance improvement. This heating effect may be augmented via the use of high power LED arrays aimed into the frozen slurry to provide additional heat input. The system/method may be applied with particular advantage to the mixing of ice cream type beverages and other viscous beverage products.

A method for preparing semisolid slurry. The method is achieved using a device for preparing semisolid slurry. The device includes a slurry vessel and a mechanical stirring rod. The mechanical stirring rod includes a first end and a second end extending into the slurry vessel. The method includes: S1. putting a molten alloy having a first preset temperature into the slurry vessel; S2. cooling the molten alloy to a second preset temperature, positioning the second end of the mechanical stirring rod to be 5-25 mm higher than the bottom wall of the slurry vessel, rotating the mechanical stirring rod and injecting a cooling medium into the mechanical stirring rod; and S3: allowing the temperature of the molten alloy to be 10-90 degrees centigrade lower than the liquidus temperature of the molten alloy, stopping stirring and cooling, to yield a semisolid slurry.
