Systems and methods for delivering a cooking medium in a cooking apparatus are disclosed. A delivery system includes a rotary valve having a rotary inlet and a plurality of rotary outlets. The rotary inlet is configured to be in fluid communication with a source of cooking medium and the plurality of rotary outlets are configured to be in fluid communication with a corresponding plurality of receptacles. A rotary position sensor generates a signal, having continuous angular position resolution, based on an angular position of the rotary valve. A controller receives the signal generated by the rotary position sensor and selectively places the rotary inlet in fluid communication with one of the plurality of rotary outlets based on the signal generated by the rotary position sensor. The rotary position sensor may include a Hall-effect sensor that functions at elevated operating temperatures associated with the cooking medium.

The invention relates to a cleaning device (100) for cleaning a container, in particular an inner wall of a container, comprising: a base member (1) that can be coupled to a feed pipe for supplying a cleaning agent, a rotating member (3) mounted rotatably about a rotational axis (A) on the base member (1), a support member (2) having a first end portion (16) and a second end portion spaced apart along the rotational axis (A),
wherein the first end portion (16) can be coupled to the base member (1) and the second end portion to the rotating member (3) in such a way that in the coupled state the rotating member (3) is rotatably accommodated between the base member (1) and the support member (2),
wherein the cleaning device (100) further comprises a coupling means (15) which is adapted to lock the support member (2) in place relative to the base member (1) in the coupled state. The invention also relates to a method for assembling a cleaning device (100).

A dry etching method which includes a dry etching step in which an etching gas containing a halogen fluoride, which is a compound of bromine or iodine and fluorine, is brought into contact with a member to be etched (12) having an etching object, which is an object to be etched by the etching gas, thereby etching the etching object without using plasma. The etching object contains at least one metal selected from among titanium, indium, and tin. Also disclosed is a production method for manufacturing a semiconductor element using the dry etching method as well as a cleaning method for cleaning an inner surface of a chamber of a semiconductor element manufacturing apparatus using the dry etching method.

A system and method for removing vegetable gums from a vegetable oil tank for subsequent reuse is provided, as well as methods of using the same. The system and method of removing vegetable gums from a vegetable oil storage tank may provide the storage tank including the vegetable gums; provide a holding tank comprising a heating element; suck the vegetable gums up from the storage tank into a first conduit; transport the vegetable gums to the holding tank via the first conduit; and heat the vegetable gums in the holding tank, wherein the holding tank is configured to facilitate movement of the holding tank.

A method for cleaning a vacuum chamber, particularly a vacuum chamber used in the manufacture of OLED devices is described. The method includes cleaning at least one of an inside of the vacuum chamber and a component inside the vacuum chamber with active species, a process gas for generating the active species includes at least 90% oxygen and 5 at least 2% argon, particularly, wherein the process gas includes about 95% oxygen and about 5% argon.

A reusable vessel comprises a first compartment to store therein a substance and a second compartment separated from the first compartment by a boundary element comprising a wall or membrane having one or more apertures therein. A valve is movable between a closed position, in which the valve seals the one or more apertures, and an open position allowing the substance to be released from the first compartment into the second compartment, or a substance in the second compartment to mix with the substance in the first compartment. A triggering mechanism is coupled to the valve to move the valve between the open and closed positions. The triggering mechanism comprises one or more external elements coupled to one or more internal cam elements to control the valve, which, when triggered causes the one or more external elements to exhibit a visible change to indicate the open and closed positions of the valve.

Embodiments of the present disclosure generally relate to clean methods for processing chambers, and more specifically relate to plasma clean methods for removing carbon films from surfaces within the processing chamber. A method for cleaning includes introducing a cleaning gas into a processing region within a processing chamber, where interior surfaces of the processing chamber have a coating containing amorphous carbon. The cleaning gas contains oxygen gas and a noble gas. The method also includes generating an ion coupled plasma (ICP) from the cleaning gas within an upper portion of the processing region and generating a bias across a substrate support in a lower portion of the processing region. The method further includes exposing the amorphous carbon to atomic oxygen ions produced from the oxygen gas and the ICP and removing the amorphous carbon from the interior surfaces with the atomic oxygen ions during a cleaning process.

Systems, methods, and computer program products are disclosed for controlling a fryer. In response to determining a filtration cycle is scheduled to occur after a current cooking cycle, a temperature set-point for a cooking medium is increased to pre-heat the cooking medium prior to the end of the cooking cycle. A heating element used to heat the cooking medium may be deactivated prior to entering the filtration cycle, and reactivated during the filtration cycle in response to the filtered cooking medium in the fry pot reaching a predetermined level. Activating the heating element during the filtration cycle may further heat the cooking medium prior to starting the next cooking cycle, thereby reducing the total time needed for filtration and reheating for a subsequent cooking cycle.

A zonal cleaning system for a hopper trailer. The zonal cleaning system includes a controlled air supply that has air tanks with outlet valves operating sequentially and cyclically for a predetermined amount of time. Upper rail assemblies are positioned relatively about and mounted to the upper portion of the sidewalls and each connects to one of the outlet valves. The upper rail assemblies have nozzles directionally oriented and the sidewall rail assemblies each have a fluid delivery line connecting to one of the outlet valves. One or more drop-down segments connects to the fluid delivery line, and each of the drop-down segments has a nozzle manifold with one or more nozzles. Activation of the controlled air supply expels air sequentially and cyclically through each of the upper rail assemblies and each of the sidewall rail assemblies.

Included are methods and systems for recycling a gas emitted from non-aqueous cleaning. An example method includes contacting a contaminated equipment with a non-aqueous cleaning material; wherein the spent non-aqueous cleaning material emits the gas. The method further comprises capturing the emitted gas, filtering the emitted gas, and recycling the emitted gas into the non-aqueous cleaning material.
