The present invention refers to a filtering device for filtering a fluid containing dissolved solutions and optionally colloidal substances, including solvents and solutes, comprising a first filter unit (12) serving to remove substances in a first filtering step by way of a membrane filtration, said removed substances having a molecular weight above a defined limit value, a second filter unit (19), disposed downstream of the first filter unit (12), for the treatment of the permeate of the first filter unit (12), wherein the second filter unit (19) comprises a filter bed comprising at least one filter material of the group comprising graphene, modified graphene, graphite, activated carbon and a zeolite compound, and a third filter unit (20), disposed downstream of the second filter unit (19), for the treatment of the permeate of the second filter unit (19), wherein the third filter unit (20) comprises a porous membrane, through which the liquid to be filtered flows in a cross-flow. The present invention provides a device with the possibility of filtration with high working pressure, avoiding possible clogging inside the adsorbing material and easy regeneration and reactivation of the adsorbing material.

Lightweight construction panels, such as plasterboard, (e.g. gypsum plasterboard) are commonly used to provide internal partitions in buildings. Sheets of plasterboard are typically carried and positioned by hand. Accordingly, it is desirable to reduce the weight of plasterboard. It is known to include an aqueous foam in the stucco slurry used to produce plasterboards. However, prior known mixers have been found to destroy foam bubbles. The present invention provides a stucco slurry mixing apparatus (100) including an inlet (130) for the introduction of foam into a mixing chamber (110), wherein the inlet (130) includes an inlet aperture (132) in a wall of the mixing chamber (110) and an inlet conduit (134) extending therefrom such that a relative angle between a longitudinal axis (136) of the inlet conduit (134) and a tangent (140) to a mixing path (124) defined by a mixing member (120) is less than 90 degrees.

Provided are an immediately-before-stirring-type fluid processing device and an immediately-before-stirring-type fluid processing method that can adjust or improve the final properties of a fluid to be processed that is introduced as a raw material into an annular flow channel of a microreactor employing the annular flow channel, which is formed between relatively rotating processing surfaces, as a flow channel in which fluid processing is performed. A fluid to be processed, which has been prepared in a fluid preparing system so as to be in an ideal state for reaction, is charged into a fluid processing device. The fluid processing device subjects the fluid to be processed to reaction processing in an annular flow channel, which is formed between two processing surfaces. A cylindrical stirring space is provided in the radially inner side of the annular flow channel, and a rotor and a screen are disposed inside the stirring space. Stirring energy is applied by the rotor and a shearing force is applied between the rotor and the screen to the fluid to be processed immediately before the fluid to be processed is introduced into the annular flow channel.

A device, which serves to separate particles of a bulk material, which is deliverable at an input location and is removable processed in different or at least approximately unitary particle sizes at an output location, includes at least one separating element, which has a metal separating plate with through-openings provided therein, which separating element can be provided with ultrasonic energy and for this purpose is connected to an ultrasonic transducer and which is held by a holding device. The holding device is a mounting shaft, which is held at one end or at both ends fixedly or movably, in particular rotatably and/or axially displaceable, and which at one end or at both ends is connected to an ultrasonic transducer, by means of which ultrasonic energy is couplable via the mounting shaft into the separating element, which is designed to be dimensionally stable.

The present disclosure discloses a yogurt maker and its method of use for using the same. A vertical upwardly extending mixing container protrusion is set at the bottom of the mixing container of the yogurt maker and a mixing head is detachably sleeved on the mixing container protrusion, and the rotation of the mixing head is driven by a power device so that the mixing head can mix the mixture in the mixing container well. At the same time, a temperature sensor is installed at the bottom of the mixing container to monitor the temperature of the mixing container, so as to ensure constant heat preservation conditions in different environments. The mixing device can be detached easily, which eliminates hygienic blind spots and ensures that the yogurt maker can be cleaned easily after making yogurt.

A bubble formation apparatus (500) includes: a rotor (100); a container (200) in which the rotor (100) is housed together with a liquid (LQ) and a gas (GS); and a rotary device (300) that causes rotation of the rotor (100) with the rotor (100) being pressed against an inner lower surface (221) that is the inner surface of the container (200). A bubble is formed by periodically repeating pressurization and depressurization of a mixture of the gas (GS) and the liquid (LQ) in a gap between the inner lower surface (221) and a portion, pressed against the inner lower surface (221), of the rotor (100) due to the rotation of the rotor (100) by the rotary device (300).
