A novel device for frothing milk is disclosed. The frothing device preferably includes a rotatable impeller and a screen disposed about the bottom of the impeller downstream of milk being pushed by the impeller. The frothing device may further include a pitcher and a base upon which the pitcher sits wherein the base includes a heater. The pitcher includes a magnetic drive capable of turning the impeller at very high speeds. The impeller is positioned off-center within the pitcher that preferably includes a tapered interior. The structure of the device and programs that adjust the speed of rotation of the impeller permit the user to create bubbles and further break the bubbles down into a silky smooth microfoam without the conventional use of a steam wand or other such device and without the skills of a professional barista.

A wireless sensor that can measure properties of a substance and transmits the properties to a remote wireless receiver is disclosed. The wireless sensor can be fully enclosed within a container containing the substance, for example, allowing remote monitoring of the properties of the substance without compromising the integrity of the closed system.

A device for storing and circulating drinking water with vortex flow includes a base, a tank and an actuator housed in the base and configured to circulate the drinking water stored in the tank with vortex flow. The base includes an inlet port through which the drinking water is received and an outlet port through which the drinking water is dispensed. The tank is mounted on the base with a sealed engagement and is configured to store the drinking water. The tank has spherical or egg shape and includes an air inlet on an upper portion of the tank through which air can flow in and out of the tank.

A cooling and heating cabinet according to an embodiment of the present invention may comprise: an inner case having a storage space provided therein; an outer case which is disposed surrounding the inner case and forms an insulation cavity between the outer case and the inner case; a thermoelectric element module disposed in the insulation cavity; a separation panel disposed inside the inner case and having a plurality of through-holes; an agitating part disposed between the separation panel and the bottom surface of the inner case, and having a magnet and an agitating fan that rotates with the magnet; and a magnetic field-generating part disposed outside the outer case, and generating a magnetic field to rotate the magnet.

A culture medium preparator includes a cylindrical vessel that terminates at the low part in a substantially hemispherical cap, a lid and a stirrer placed in the vessel. The stirrer includes a vertical tube placed in the center of the vessel, a plurality of blades put into rotation about the tube and magnetic masses at the periphery so that they are placed in proximity to the internal wall of the vessel. The preparator furthermore includes a magnetic ring in rotation about the internal wall at the same height as the magnetic masses. The magnets attract the magnetic masses, the magnetic ring being moved in rotation by a motor. In this way, the stirrer is driven in rotation without requiring mechanical elements placed inside the vessel, the absence of such elements facilitating the cleaning.

An apparatus for agitating liquid foodstuff, comprising a whisk that includes a magnetic rotor of a brushless electromotor assembly, and a main body including a liquid foodstuff container in which the whisk is receivable such that it is rotatable around a rotation axis thereof, and a stator of the electromotor assembly. The stator is configured to electromagnetically drive the rotor in rotation, and includes at least one magnetic sensor configured to provide a signal that reflects positional changes of the magnetic rotor relative to the magnetic sensor. The main body also includes a controller configured to detect an initial, manually effected rotational movement of the whisk around its rotation axis from the signal of the magnetic sensor, and, once such initial movement of the whisk is detected, to operate the apparatus independent of said initial, movement.

The invention relates to a dispersion tool (4) that can be cleaned more easily. For this purpose, the dispersion rotor (8) is arranged on the dispersion tool (4) axially moveable between the working position in the shaft tube (5) and the cleaning position outside the shaft tube (5), the dispersion rotor (8), in the cleaning position, being preferably completely arranged outside the shaft tube (5) and therefore being more easily cleanable.

The present disclosure relates to improved magnetic mixing assemblies and mixing system. The magnetic mixing assemblies can provide improved mixing action, ease of use, and low friction. The mixing assemblies can be adapted for use with a wide variety of containers including narrower neck containers and flexible containers.

An impeller (18), for example, a Rushton impeller for a bioreactor system (10) is disclosed. The impeller (18) includes a hub (44), optionaly including a slot (168), a plurality of blades (46), and one or more turbulators (64). The plurality of blades (46) is disposed along a circumferential direction (48) of the hub (44) and spaced apart from each other. Each of the plurality of blades (46) is coupled to at least a portion of a circumference (50) and/or a top surface (1351;1451;1551) of the hub (44). Each blade of the plurality of blades (46) includes a pressure face (52) and a suction face (54). The one or more turbulators (64) is disposed on at least a portion of the suction face (54), the pressure face (52), or both, of a blade of the plurality of blades (46).
