Method for producing a confectionery semi-processed product, such as a chocolate-type product

摘要

A method of producing a semifinished confectionary product, such as chocolate or similar, using at least one centrifugal unit for simultaneously grinding and mixing at least some of the ingredients of the semifinished product, and which includes an elongated processing chamber with a substantially horizontal axis, at least one inlet for the ingredients to be processed and one outlet for the processed ingredients, and a powered shaft fitted inside the processing chamber, coaxially with the axis, and fitted with a succession of radial appendixes arranged between the inlet and the outlet; the method including the steps of loading at least a first ingredient of the semifinished product through the inlet; grinding the first ingredient inside the grinding and mixing unit by rotating the shaft at a first speed; loading at least a second ingredient through the inlet, after grinding; rotating the shaft at a second speed to grind and mix the ingredients to form a mixture of the same grain size as the semifinished product; loading at least a third ingredient through the inlet; mixing the third ingredient with the previously ground mixture to form a further mixture; bringing the further mixture to a given temperature to obtain the semifinished product; and transferring the semifinished product to a storage or packaging station.

主权项

1. A method of producing a semifinished confectionary product having a grain size, comprising:
providing a first centrifugal unit having a tubular shell closed at opposite ends by two walls for defining an elongated processing chamber housing a motorized shaft fitted integrally with one or more coiled rows of radial appendices; providing a second centrifugal unit having a tubular shell closed at opposite ends by two walls for defining an elongated processing chamber housing a motorized shaft fitted integrally with one or more coiled rows of radial appendices; providing a third centrifugal unit having a tubular shell closed at opposite ends by two walls for defining an elongated processing chamber housing a motorized shaft fitted integrally with one or more coiled rows of radial appendices; grinding sugar within the first centrifugal unit from a first grain size to a second grain size, the second grain size being smaller than the first grain size, the second grain size being larger than the grain size of said semifinished confectionary product, and outputting ground sugar from said first centrifugal unit; mixing said ground sugar with at least one second ingredient inside said processing chamber of said second centrifugal unit by rotating said shaft of said second centrifugal unit inside said chamber of said second centrifugal unit to move said ground sugar and said at least one second ingredient inside said chamber of said second centrifugal unit along at least one straight, horizontal, simultaneous grinding and mixing path, and to simultaneously grind and mix the ground sugar and the at least one second ingredient to form a mixture of the same grain size as the grain size of said semifinished confectionary product; taking said mixture out of said chamber of said second centrifugal unit through an outlet of said processing chamber of said second centrifugal unit, wherein said step of simultaneous grinding and mixing includes spinning the whole of said ground sugar and of said at least one second ingredient onto lateral walls of said processing chamber of said second centrifugal unit to form a layer of a predetermined thickness thereon; a difference in speed between said layer on said lateral walls and said radial appendices of said second centrifugal unit producing relative movement, and therefore thorough mixing and grinding; and inputting said mixture into the third centrifugal unit.
