Abstract: A mixing device includes a plurality of elongated ampules mounted on a rotatable support with the longitudinal axis of each ampule inclined inwardly toward the rotational axis of the rotatable support. When the mixing device rotates about the rotational support, centrifugal force causes fluid in each ampule to move toward the end farthest away from the rotatable support. A bubble in each ampule then moves toward the opposite end. In one embodiment, the rotational support is inclined so that the end of each ampule positioned farthest from the rotational support is positioned sufficiently above the other end so that the bubble rises to the end farther from the support in at least one position as the support rotates. As a result, a bubble in each ampule moves back and forth between the ends of the ampule as the rotatable support rotates to mix respective fluids in the ampules.

Abstract: A system for controlling the moisture content of moisture absorbing fruit products to achieve a uniform moisture content of the product. The continuous flow of raw product in chip, diced, extruded or comminuted form initially enters a rotating reel where the product is tumbled and exposed to a high-humidity environment for increasing the moisture content beyond a target value. The added humidity can be in the form of steam or water spray.

Although the original moisture content of raw fruit product entering the system may vary considerably, contact between product during mixing in the moisture adding and drying reels causes the final product to assume uniform and consistent characteristics.
