Abstract: Provided is an one-pass type dispersing and emulsifying apparatus, including: a chamber, at both sides of which an inlet for inputting a liquid and an outlet for discharging the liquid is arranged to provide a moving path for the liquid therein; a shaft rotatably arranged inside the chamber; a motor arranged for rotating the shaft; a rotation impeller fixed to the shaft as a plurality at a predetermined interval along a length direction and arranged on the moving path for the liquid, wherein at each rotation impeller, a first blade extended toward the inner circumferential surface of a fixing impeller is formed at a predetermined interval as a plurality along the length direction of the shaft; and a fixing impeller provided on the inner surface of the chamber as a plurality along the length direction of the shaft to be disposed around the rotation impeller.

Abstract: The machine comprises a hollow rotary body (1) of large dimensions which may be loaded with the containers to be recycled, nozzles for supplying and spraying washing fluid at a predetermined temperature to the rotary body (1) for the mutual separation and washing of the containers and the initial separation of labels and bases, and mechanical impact devices (2), (21, 23) housed in the rotary body (1) and actuated by the rotation of this body so as to exert on the containers a mechanical action suitable for the mutual separation of the containers themselves, the separation of the stoppers and the completion of the washing and label and base separation operation. The rotary body (1) may have an inlet opening (5) and an outlet opening (7) for the containers to be recycled or a single inlet and outlet opening (30) so as to form a machine operating continuously or discontinuously respectively.

Abstract: Chocolate is ground in order to obtain a very small average particle size. A determined viscosity is necessary for further processing. In order to keep as small as possible the fraction with particle size lying above the desired value and having an adverse effect on the taste of the final product, according to the invention the process mass is circulated in a cycle incorporating a grinding device and a ball mill. This has the result of accelerating the grinding process and reducing the inconsistency in the distribution of the particle size.
