A screw-type separation device 1 includes a casing 10 including an object discharging port and discharging an object A having been dehydrated, and a separated liquid discharging port; a screw shaft provided inside the casing and extending in an extending direction that is a direction from the one end part to the other end part; a first screw blade extending spirally on an outer peripheral surface of the screw shaft; and a second screw blade extending spirally on the outer peripheral surface of the screw shaft such that a predetermined gap is formed with respect to the first screw blade in the extending direction. A groove is formed on an inner peripheral surface of the casing.

A noodle boiling apparatus includes a noodle boiling unit, and a hot water supply mechanism supplying water, which is heated, to the noodle boiling unit. The noodle boiling unit includes a boiling tank storing the water and boiling noodles, a hot water pipe supplying the water, which is heated, to the boiling tank, and a discharge pipe discharging the water from the boiling tank to the hot water supply mechanism. The hot water supply mechanism includes a heat exchanger heating the water to a desired temperature and a circulation pump pumping the water to the heat exchanger. The hot water supply mechanism is configured to circulate the water constantly between the boiling tank and the hot water supply mechanism when the noodles are boiled.

A cleaning device includes a supporting mechanism, a clamping mechanism arranged on the supporting mechanism and used to clamp a spray head, a heating mechanism, an adjusting mechanism, and a cleaning mechanism. The heating mechanism, the adjusting mechanism, and the cleaning mechanism are arranged on the supporting mechanism. The heating mechanism is used to heat the spray head clamped by the clamping mechanism. The cleaning mechanism is used to inject cleaning liquid into the spray head, dredge the spray head, and detect the spray head. The adjusting mechanism is used to rotate and adjust a position of the cleaning mechanism to complete different tasks on the spray head.

A novel cleaning container is disclosed for backflushing and hence clean an espresso machine. The container may include a body having a top, an opposing bottom, and an interior cavity for holding water, detergent, and/or other cleaning fluid. A piston is slidably disposed within the interior cavity between up and down positions, wherein the piston and an opening of the body at the top define a variable volume for cleaning the machine. A spring is seated firmly within the body underneath the piston for biasing the piston to the up position. A stopper disposed about the top of the piston limits the motion of the piston at the top of the body. One or more grooves within the body are in fluid communication with one or more outlets to permit fluid to exit the body during cleaning. The body may be transparent or translucent.

Embodiments of a system and method for endoscope cleaning and inspection are disclosed. In an example, an endoscope cleaning and inspection unit includes cleaning and testing capabilities operated via control equipment and a display screen, to operate leak testing equipment, flush control equipment, and optical inspection equipment for leak testing, flushing, rinsing, and inspection of an endoscope interior chamber (lumen) and exterior surfaces. In a further example, the endoscope cleaning and inspection unit may further operate and receive information from a borescope imaging device or a magnification imaging device, using an imaging sensor to capture images of an endoscope lumen or surface respectively, as captured or output on the display screen. Further embodiments provide for control, monitoring, data collection, data input, and data output with such imaging devices via the endoscope cleaning and inspection unit.

The present disclosure provides a cleaning system, including a first sub-chamber, a second sub-chamber adjacent to the first sub-chamber, and a third sub-chamber adjacent to the second sub-chamber. A first divider is positioned between the first and the second sub-chambers. A second divider is positioned between the second and the third sub-chambers. A vacuum system is coupled to the third sub-chamber to generate a vacuum pressure in the third sub-chamber that is less than a pressure of the first sub-chamber to create a pressure differential to induce a pressurized flow of a first cleaning media from the first sub-chamber to the third sub-chamber through an internal passage of a component positioned in the second sub-chamber. A filtering system is coupled to the first sub-chamber and the third sub-chamber to remove and filter the first cleaning media from the third sub-chamber and return the first cleaning media to the first sub-chamber.

A back-blush cleaning container may have a spring-biased piston that allows the container to fill with hot water when attached to a group head of the espresso machine. When the hot water of the espresso machine is turned off, the piston due to the spring urges the hot water out and back through a 3-way valve to clean the espresso machine. The backflush cleaning container also may have a steam conduit that allows steam from a steam wand of the espresso machine to clean the group head, 3-way valve and tubes. Moreover, the container may have a window which based on the position of the piston, a particular color is shown. The colors indicate whether the container is safe to remove from the group head of the espresso machine and when the container is full of water.

Valve and related assemblies, systems, and methods may include a self-cleaning feature that may be configured to at least partially displace material from a portion of the valve. Such valves may be utilized in a pressure exchanger.

The invention relates to compositions and methods for reducing biocontaminant (for example flesh, blood, mucous, faeces or biofilm) on a surface, such as an endoscope surface. The compositions are viscoelastic and of low lubricity, having the following properties at 21° C.: a rotational yield point between 140% strain and 300% strain; a peak viscosity between 550 Pa.Math.s and 2000 Pa.Math.s; an oscillatory flow point between 250 and 700% strain; and a coefficient of friction μ which has a maximum value (preferably 0.06 or greater) in the viscoelastic liquid's elastohydrodynamic region.

A surgical instrument according to an embodiment may include: a shaft; an end effector provided on a side of one end of the shaft; a housing provided on a side of the other end of the shaft and including a base including an attachment surface to be attached to a robot arm, a lid portion covering the base, and cleaning liquid supply holes to supply a cleaning liquid; and a cleaning tube to supply the cleaning liquid into the shaft. The cleaning liquid supply holes include: a first cleaning liquid supply hole to which the cleaning tube is attached; a second cleaning liquid supply hole communicating with an inside of the housing; and a third cleaning liquid supply hole opening in a direction substantially orthogonal to an opening direction of the second cleaning liquid supply hole and communicating with the inside of the housing.
