Food dispenser and method for portioning and dispensing free-flowing foods

摘要

Food dispenser for free-flowing food has a piston movable in a reciprocal manner in a cylinder by a drive and having a valve (2) having a valve body (5) which is rotatable about a rotational axis (7) between a first and a second switching position. In the first switching position, a first channel (14) of valve body (5) connects a suction opening (11) and a working opening of piston (12), such that a working stroke of the piston suctions food through suction opening (11) and working opening (12) into an intermediate space. In the second switching position, a second channel (15) of valve body (5) connects working opening (12) and a dispensing opening (13) such that a second working stroke of the piston conveys food from the cylinder through working opening (12) and dispensing opening (13). The suction opening (11), working opening (12) and dispensing opening (13) are offset, spaced from one another along rotational axis (7) of the valve body (5).

主权项

1. Food dispenser for portioning and dispensing free-flowing food, comprising a piston which is able to move in a reciprocal manner in a cylinder by means of a drive and having a valve (2) comprising a valve body (5) which is able to be rotatably driven exclusively about a rotational axis (7) between a first and a second switching position, in the first switching position by means of a first channel (14) delimited by the valve body (5) a fluidic connection being created between a suction opening (11) and a working opening assigned to the piston (12), such that by means of a working stroke of the piston, food is able to be suctioned through the suction opening (11) and the working opening (12) into an intermediate space, which in particular is formed in the cylinder, and in the second switching position by means of a second channel (15) delimited by the valve body (5), a fluidic connection being created between the working opening (12) and a dispensing opening (13) such that by means of a second working stroke of the piston in a second axial direction counter to the first axial direction, food is able to be conveyed from the cylinder through the working opening (12) and the dispensing opening (13), the suction opening (11), the working opening (12) and the dispensing opening (13) being arranged offset, spaced apart from one another, along the rotational axis (7) of the valve body (5),
wherein the first channel (14) is configured as an outwardly open first groove (16) and wherein at least one side wall (20, 21) of the first groove is/are helical and/or wherein the second channel is configured as an outwardly open second groove (17) and wherein at least one side wall (20, 21) of the second groove is/are helical.
