Method and apparatus for cutting high viscosity liquid material, said apparatus comprising a cylinder divided into upper and lower tanks by a partition with a central discharge opening, a moveable and elevatable liquid supply pipe with a distal end positioned opposite the discharge opening, the liquid supply pipe being mounted so that it can be raised until its distal end contacts the partition around the discharge opening, and then lowered until there is no contact, means for raising and lowering the liquid supply pipe, the upper tank having peripheral injection ports for injecting a low viscosity liquid into the upper tank, means for feeding high viscosity liquid material into the lower tank and flowing it into the upper tank, means for feeding low viscosity liquid into the liquid supply pipe and for feeding low viscosity liquid into the peripheral injection ports, the high viscosity liquid material flowing from the lower tank into the upper tank when the liquid supply pipe is lowered, the high viscosity liquid material being pushed upwardly into the upper tank by the low viscosity liquid when the liquid supply pipe is raised, whereby the high viscosity liquid material being pushed upwardly in the upper tank is cut into blocks by the low viscosity liquid being injected into the upper tank.

Method and apparatus for cutting high viscosity liquid material

A continuous mixer for liquids comprises a casing having a conical interior surface and a discharge outlet at the apex of the cone formed by the conical interior surface, a rotor that rotates at its center on the axis of the cone and has a conical exterior surface whose vertical angle is approximately equal to the vertical angle of the conical interior surface, a pressure-transport device that has one or more feed lines which communicate with a gap between the interior surface of the casing and the exterior surface of the rotor a position removed from the discharge outlet and that delivers one or more liquid inputs under pressure through the feed lines, and a gap-adjustment device capable of axially adjusting the rotor within the casing to adjust the gap. The internal pressure and temperature or the mixer can be controlled or adjusted while the rotor is rotating by changing the gap width along the axial direction.
