The present invention provides a turntable color machine includes a rack, a controller is arranged on the rack, a wheel-type turntable that rotates vertically is arranged on the rack, a plurality of color paste bags are arranged on the wheel-type turntable, the color paste bags are evenly arranged along the circumference of the wheel-type turntable, the color paste bags are connected with a piston pump that is driven by a lifting mechanism to perform constant volume injection via a valve body, and a material receiving device that moves up and down is arranged at the middle of the wheel-type turntable. The piston pump is connected with the color paste bags to achieve volume injection, the wheel-type turntable drives the color paste bags to perform a circular motion, so that the color paste in the color paste bags are turned up and down to achieve an even mixing effect, no stirring device needs to be added, so that the manufacturing cost is reduced, the plunger valves are arranged in the color paste bags, the air in the color paste bags is extracted through the air suction cylinder to ensure that there is no air in the color paste bags, to prevent the color paste from deteriorating and to prolong the service life of the color paste.

A cleaning device for a mixing vessel of a food processor operated by an electric motor, wherein the mixing vessel has a vessel bottom, a circumferential wall and a cover element, wherein the cleaning device can be connected to a rotary element positioned in the mixing vessel of the food processor in a torque-proof manner with the aid of a fastening means and is designed for sweeping over at least a partial area of an inner wall of the mixing vessel and mechanically removing deposits located thereon during a rotation of the rotary element about a rotational axis. The cleaning device has a C-shaped design that is in contact with the vessel bottom, the circumferential wall and the cover element such that cleaning of the vessel bottom, the circumferential wall and the cover element can take place simultaneously when the mixing vessel is closed with the cover element.

A mixing vessel for a food processor operated by an electric motor, which mixing vessel has a mixing mechanism which can be connected to a rotary drive of the food processor by means of a coupling driver, wherein the mixing vessel has a cleaning device for cleaning an inner wall of the mixing vessel, in particular a floor of the vessel. The cleaning device is arranged on the mixing vessel, in particular on a vessel wall and/or the mixing mechanism, and has at least one cleaning element which is designed such that, upon actuation of the cleaning device, it sweeps over the inner wall and/or over sub-regions of the mixing mechanism and, by interacting mechanically with any deposits which may be located on the inner wall and/or the mixing mechanism, helps to remove the same. The mixing vessel can have a cleaning device which has an ultrasonic transmitter, which is arranged in a fixed position in a wall of the mixing vessel or which is arranged, in particular in a removable manner, in the interior of the mixing vessel.

A valve for injecting a fluid into a bowl has a vent with an inlet and a flexible diaphragm for covering the discharge opening of the vent. The diaphragm is connected to a vessel body of a bowl, and the vent is connected to a stand of a bowl. The diaphragm has a closing area for closing the discharge opening and a connecting area for connecting the diaphragm with the vessel body spaced to the vent. At least one window is provided between the closing area and the connecting area.

What is presented and described is a method for avoiding the microbial attack of a cleaning apparatus, in particular a cleaning apparatus for a metering system, wherein the cleaning apparatus has at least one mechanical cleaning element with at least one cleaning surface, wherein the method is characterized in that the at least one cleaning surface of the at least one mechanical cleaning element is exposed, at least temporarily, to an oxidizing agent. The present invention further relates to a method for cleaning a metering system, in particular for a dispersion, especially a paint-metering system, to a cleaning apparatus, and to a metering system.

A bioreactor (30) for production and harvesting of microalgae is described, comprising a reactor basin (32) in the form of a tank arranged to receive CO2 and water as well as algae, and which is equipped with at least one outlet for harvesting of algal biomass, where the reactor basin (32) comprises a rotating beam (54) equipped with one or more tillable mixing grates (60) and harvesting grates (62).
