A feed-mixing device for receiving, mixing and dispensing animal feed includes a frame with a mixing bin for receiving and mixing the animal feed therein and dispensing it therefrom, at least one mixing device rotatably drivable in the mixing bin using a drive, in particular a vertical mixing auger, for mixing the received animal feed, and a weighing device for determining the weight of the animal feed received in the mixing bin, comprising N weighing elements, with N≥2, each of which emits a weighing signal, and a control system for controlling the feed-mixing device and for processing the weighing signals from the weighing elements to produce the determined weight. The control system is configured to perform an, in particular fully automatic, calibration action of the weighing elements. The calibration action includes driving the at least one mixing device, reading out the respective weighing signal of each of the N weighing elements in each of M different positions of the mixing device, with M≥N, calibrating the weighing elements on the basis of the read-out weighing signals, wherein the calibrating at least includes determining a respective correction factor for the weighing signal of each weighing element by analysing the read-out weighing signals of all weighing elements. Thus, all weighing elements may be calibrated without having to detach the weighing elements, which provides very reliable weight measurements in a very simple manner.

The disclosure relates to a mixing device and a liquid mixing method. The mixing device comprises a first clamping assembly, a second clamping assembly and a driving assembly, the first clamping assembly is used for fixing a first container containing a first liquid, the second clamping assembly is used for fixing a second container containing a second liquid, the first container and the second container are in communication, the driving assembly drives the first liquid and the second liquid to flow back and forth between the first container and the second container to complete a predetermined degree of mixing to form a third liquid. The flow speed of the first liquid and the second liquid driven by the driving assembly is accurately controlled, so that an iodized oil emulsion with better physical and chemical characteristics is prepared, and an emulsion with better emulsifying effect and treatment effect is obtained.

A fluid handling apparatus for ejecting fluid into a tank and draining fluid from the tank comprises: a fluid duct for draining/supplying fluid from/to the tank, the fluid duct configured for fluid communication with a tank opening at a tank bottom; a fluid inlet pipe for supplying fluid to the tank, the fluid inlet pipe extending at least partly through the fluid duct and configured to extend through the tank opening into the tank; a rotary fluid ejection device in fluid communication with the fluid inlet pipe; and a rotary drive shaft extending at least partly inside the fluid inlet pipe, the rotary drive shaft being rotatably connected to the rotary fluid ejection device. Also disclosed is a fluid tank system comprising a tank and a fluid handling apparatus, and a method for mixing beer or wort with solid hops material in a tank by a fluid handling apparatus.

An adapter couples to a container and includes an adapter body and a mixing element. The adapter body includes a neck section and a cap section. The neck section has a first interior surface that defines a first channel extending therethrough. The cap section is coupled to the neck section. The cap section has a second interior surface that defines a second channel extending therethrough that is in fluid communication with the first channel. The mixing element is coupled to the first interior surface and extends into the first channel.

A mixer for mixing and degassing fluids includes a revolution device having a revolution base to be driven for rotation; a first spin device connected to the revolution base of the revolution device; a first barrel connected to the first spin device to be spun by the first spin device; an transmitting coil electrically connected to a power source to generate a time-vary magnetic field; and a receiving coil connected to the revolution base of the revolution device and electrically connected to the first spin device, wherein the receiving coil rotates with the revolution base. The receiving coil receives the power from the time-vary magnetic field of the transmitting coil and produces an electromotive force to be supplied to the first spin device.

An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis subsystems can be used to analyze soil, vegetation, and/or manure samples.

Described is a device for granulating a powder to be granulated or a powder mixture to be granulated. The device includes at least one working vessel in which the powder to be granulated or the powder mixture to be granulated is provided, at least one mixer for mixing the powder to be granulated or the powder mixture to be granulated, at least one dosing device for granulating liquid, and at least one drive unit that includes a rotational speed range for providing a drive torque required for the mixer. The drive unit provides a uniformly high drive torque over its entire rotational speed range. Also described is a method for granulating a powder to be granulated or a powder mixture to be granulated using such a device.

Methods for in situ mixing of two or more different liquid compositions by employing a dynamic flow profile characterized by a ramping-up section and/or a ramping-down section.

An antibody-resin coupling apparatus quickly and efficiently activates resin beads and couples them to antibodies, while preventing breakdown and crosslinking of the beads, thereby improving downstream column purification processes, extending the usable life of the resin beads, and increasing molecule capture efficiency of the resultant resin-antibody complexes, to allow improved isolation and purification of factor VIII molecules or other drug compounds.

An apparatus is provided that is configured to be used with a container having contents to permit mixing of the contents of the container. The apparatus includes a main body having a geometrical shape having an open end, a closed end, and a longitudinally extending bore or opening extending from the open end to the closed end. The opening or bore is configured to receive at least a portion of a container. A shaft is generally orthogonally positioned from a portion of the closed end. The shaft is configured to be received by a rotational device. The mixing apparatus can be used to mix various sized containers containing contents having one or more materials to be mixed. The container is not attached to any portion of the main body and the container is configured to rotate freely and independently of the main body during an operation of the rotational device.
