DEVICE FOR MIXING AND/OR KNEADING FOOD PRODUCTS

摘要

The invention relates to a device for mixing and/or kneading food products. The device is provided with at least one container having a container inlet and, spaced therefrom, a container outlet, and at least one rotary shaft extending substantially in the longitudinal direction of the container between the container inlet and the container outlet. The shaft is provided with a mixing and/or kneading element for mixing and/or kneading the food products substantially in a continuous manner. In the container, an operative space is formed between the container inlet and the container outlet, where mixing and/or kneading of the food products is to take place. According to the invention, the device is provided with pressure means for adjusting the pressure in the operative space, and with pushing means for at least partially forming a sealing wall of the operative space with the food products to be mixed and/or kneaded.

1. A device for mixing and/or kneading food products, in particular foodstuffs, in which the device is provided with at least one container having a container inlet and, spaced therefrom, a container outlet, as well as at least one rotary shaft extending substantially in the longitudinal direction of the container between the container inlet and the container outlet, which shaft is provided with a mixing and/or kneading element for mixing and/or kneading the food products substantially in a continuous manner, wherein the mixing and/or kneading element comprises a bar which helically surrounds the shaft, spaced therefrom by spacers, wherein the device is further designed for transporting the food products from the container inlet to the container outlet, wherein an operative space is formed between the container inlet and the container outlet in the container, where mixing and/or kneading of the food products is to take place, wherein the device is provided with pressure means, such as a vacuum pump unit, for adjusting the pressure in the operative space, and also with pushing means for at least partially forming a sealing wall of the operative space with the food products to be mixed and/or kneaded so as to thus maintain the pressure in the operative space, characterised in that, seen in cross-sectional view of the cylinder, the distance between a radially outward point on the mixing and/or kneading element and the inner side of the container varies during rotation of the shaft, wherein the distance between the point on the mixing and/or kneading element and the inner side of the container is smaller near a point above the shaft than near a point below the shaft, at least in an operative condition of the device.
