Abstract
A device for blending materials comprising a carrier support (1) arranged to support a closed bag (3) containing a material to be blended, a kneading mechanism in the form of paddles (5) which are arranged to apply a kneading action to the bag walls for homogenizing its contents, and a clamping device (4) for holding the bag closed and against the carrier support (1) during kneading. The kneading mechanism (5) is arranged to act in conjunction with the carrier support (1) and an island baffle (7) to cause the contents of the bag to circulate during kneading.

A device for blending materials comprising a carrier support arranged to support a closed bag containing a material to be blended, a pair of kneading paddles arranged to apply a kneading action to the bag walls for homogenizing its contents, and a bag holder for holding the closed bag against the carrier support during kneading, the pair of kneading paddles being arranged to act in conjunction with the carrier support to cause the contents of the bag to circulate during kneading, wherein each kneading paddle in the pair of kneading paddles is arranged to act on a different area of the bag and there is an island baffle provided between the kneading paddles in said pair of kneading paddles to substantially prevent movement of material transversely through a central region of the bag.
An assembly for blending materials comprising a sample bag having an arcuate internal boundary in a plane of intended circulation and a device for blending materials comprising a carrier support arranged to support the sample bag containing a material to be blended, a pair of kneading paddles arranged to apply a kneading action to the bag walls for homogenizing its contents, and a bag holder for holding the sample bag against the carrier support during kneading, the pair of kneading paddles being arranged to act in conjunction with the carrier support to cause the contents of the sample bag to circulate during kneading, wherein each paddle in the pair of kneading paddles is arranged to act on a different area of the sample bag and there is an island baffle provided between the kneading paddles in said pair of kneading paddles to substantially prevent movement of material transversely through a central region of the sample bag.
A device for blending materials comprising a carrier support arranged to support a closed bag containing a material to be blended, a kneading means which is arranged to apply a kneading action to the bag walls for homogenizing its contents, and holding means for holding the closed bag against the carrier support during kneading, the kneading means being arranged to act in conjunction with the carrier support to cause the contents of the bag to circulate during kneading, wherein the kneading means comprises a pair of paddles, each paddle in said pair being arranged to act on a different area of the bag and there being an island baffle provided between the paddles to substantially prevent movement of material transversely through a central region of the bag.
