Abstract:
A mixing device, comprising:an input container configured for receiving a product that comprises a fluid component and a second component; a whipper having a tapered whipper surface that has an axis and that is configured for aerating and frothing the product, the whipper surface extending between first and second surface ends, the first surface end having a first diameter of at least about 18 mm and being in fluid communication with the input container to receive the product, and the second surface end being disposed downstream of the first surface end and having a second diameter that is larger than the first diameter, wherein the whipper surface is oriented at a surface angle to the axis of less than 90Â° to extend the whipping surface with a sufficient length and surface area to provide a high frothing efficiency; a motor in driving association with the whipper for rotating the whipper about the axis at a speed sufficient for aerating and frothing the product; and a product exit conduit disposed downstream of the whipper and configured for dispensing the product of the fluid and second components.
