Abstract:
A coffee processor having a grinder and a densifier is disclosed. The densifier comprises an elongated housing having a mixing chamber configured to receive ground coffee. The mixing chamber has an inlet end opposite a discharge end. The discharge end has a discharge door. The densifier has a mixing shaft driven by a mixing motor, the mixing shaft extending along a longitudinal length of the mixing chamber. The densifier has a plurality of pins fixed to the mixing shaft and configured to agitate a bed of coffee within the mixing chamber. An automatic coffee density control system is also disclosed. A controller is configured to signal a discharge door actuator to move the discharge door a predefined distance to increase or decrease the mixer motor load when the mixer motor load sensor reports a mixer motor load value that is outside a predefined mixer motor load operating range or setpoint.
Abstract:
A machine for processing food products in at least one basin (12a, 12b) with the use of a mixer (13a, 13b) activated by a motor (11a, 11b) controlled by an inverter (10a, 10b), in turn in communication with an electronic card with a micro-processor (1), equipped with an electronic bidirectional communication circuit (9) with serial transmission and protocol of the Modbus, Canbus or Profibus type, suitable for revealing the instantaneous state of said inverter (10a, 10b). The process and machine of the invention offer the advantage of controlling the effective execution of each processing phase of the product, repeating it automatically if this is not so.
Abstract:
A mixer nozzle assembly for mixing fluid introduced into a tank having a tank volume therein. The mixer nozzle assembly includes a stationary body and a rotatable body mounted on the stationary body for rotation about an axis in a predetermined direction. The fluid flows through the stationary body to the rotatable body and exits into the tank volume via one or more outlet apertures for causing the rotatable body to rotate in the predetermined direction about the axis. The mixer nozzle assembly also includes a governor subassembly for controlling a speed of rotation of the rotatable body in the predetermined direction about the axis and a hydraulic circuit for governing a flow rate of hydraulic fluid directed to the governor subassembly, to adjust the flow rate of the hydraulic fluid for adjusting the speed of rotation of the rotatable body to the preselected speed.
Abstract:
A stir system for stirring a liquid in a vial includes a top for at least partially closing the vial and a stirrer rotatable mounted in the top. The stirrer extends from the top into the vial and the stirrer is being connected with a magnet, which is rotatable during use by a rotating magnet field so as to rotate the stirrer in the vial. The system further includes a holder for holding the vial and a cover for covering the vial in the holder.
Abstract:
A method for the continuous phase conversion of a product in a kneader mixer, into which the product is introduced, said mixer comprising kneading elements that are mounted on at least one shaft. The product is back-mixed until a predefined viscosity of the product is determined by measurement of the torque of the shaft, or a product with a predetermined viscosity that has already been achieved is back-mixed, the kneader mixer is then switched to a continuous mode, in which optionally and additional component is added and the product is subsequently transported to the discharge point.
Abstract:
According to the invention, an apparatus for mixing laboratory vessel contents, in particular, said apparatus having an accommodating adapter having a holder for accommodating vessels, in particular laboratory vessels, in particular in exchangeable thermoblocks, and a drive which can be used to put the accommodating adapter into a mixing movement which essentially oscillates in a circular and translatory manner in a horizontal plane, is distinguished by a sensor which measures a vectorial variable which is dependent on the mass of a load of the accommodating adapter.
Abstract:
Devices and methods for controlling and monitoring the progress and properties of multiple reactions are disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight. Computer-based methods are disclosed for process monitoring and control, and for data display and analysis.

Abstract:
A method for cleaning a substrate with sherbet-like composition, comprising mixing the liquid organic agent and pure water in a mixing vessel to form a mixture, supercooling the mixture uniformly at a predetermined temperature while stirring the mixture, wherein the stirring includes creating vortices in the mixture, growing the vortices and diffusing the grown vortices in the mixture, thus providing sherbet-like cleaning composition and moving the sherbet-like cleaning composition relative to the substrate to be cleaned.
Abstract:
In a method for controlling the mixing of dough ingredients in a mixer, dough ingredients are mixed. The amount of power supplied to the mixer is measured in specified time intervals. Data relating to the amount of power supplied are stored. Based on the stored data, a decline in the amount of power supplied to the mixer is identified and the mixer mixes the dough ingredients for a predetermined period of time after the decline is identified. A mixer of the present invention includes a mixing device, a motor coupled to the mixing device, a power source coupled to the motor, and a mixing-time controller.
