The truss assembly is configured to place the robot into the oil tank through the hole. The walking assembly is configured to drive the robot to move along the axis of the oil tank and to prevent the robot from toppling in the oil tank. The power unit is configured to clean the inside of the oil tank. The walking assembly includes two active walking assemblies, a drive assembly, and a folding assembly.

A material cleaning device and a cooking appliance. The material cleaning device comprises: a cleaning chamber, an air inlet, a material inlet, and a water inlet being provided on the cleaning chamber, the air inlet, the material inlet, and the water inlet being respectively used for transporting air flows, a material to be cleaned, and water for cleaning the material to the cleaning chamber; and a stirring assembly provided in the cleaning chamber and being capable of rotating in the cleaning chamber under the action of the air streams, so as to stir the material and the water in the cleaning chamber. The material cleaning device drives the stirring assembly to rotate by means of air streams, so as to make the stirring assembly stir the material and the water in the cleaning chamber, thereby implementing automatic cleaning. The material cleaning device features a simple structure, and is easy to use.

The invention relates to a centrifuge for cleaning a reaction vessel unit and to a method for cleaning such a centrifuge. The centrifuge has a rotor and a rotor chamber, in which the rotor is arranged and mounted, the rotor features a receiving area for receiving the reaction vessel unit. The rotor chamber is limited by a housing, the housing having an outlet to drain the liquid discharged from the reaction vessels and being provided with an inlet for filling the rotor chamber with a cleaning solution in such a way, when the rotor rotates, the rotor 2 is at least partially immersed in the cleaning solution and distributes it in rotor chamber and/or the inlet is designed in such a way that the cleaning solution is distributed in rotor chamber when it is supplied by the rotating rotor.

There is provided a technique that includes a first annealing step of annealing the reaction tube; a first cleaning step of cleaning an inner surface of the reaction tube, after the first annealing step, with a liquid including a fluorine compound having a first concentration; a first rinsing step of washing away the fluorine compound used in the first cleaning step with pure water; a second annealing step of annealing the reaction tube; a second cleaning step of cleaning the inner surface of the reaction tube, after the second annealing step, with a liquid including a fluorine compound having a second concentration higher than the first concentration; and a second rinsing step of washing away the fluorine compound used in the second cleaning step with pure water.

The invention is directed to methods of generating carbonate in situ in a use solution under an enriched CO.sub.2 atmosphere. In another aspect, the invention is directed to methods of cleaning food processing surfaces under an enriched CO.sub.2 atmosphere comprising contacting a food processing surface with a cleaning composition comprised of an alkalinity source, a surfactant, and water, monitoring the pH during the wash cycle and adjusting the pH by recirculating a use solution, adding a secondary alkalinity source, or both recirculating a use solution and adding a secondary alkalinity source, to generate carbonate in situ in the use solution. In a particular embodiment of the invention the alkalinity source is an alkali metal carbonate and the secondary alkalinity source is an alkali metal hydroxide.

A bulk HPP container (10) includes a flexible body portion (12) having closed off ends (14), at least one of which is depicted as being recessed to enable the containers (10) to be positioned end-to-end in an efficient manner, for example, when placed into an HPP pressure vessel, such as a wire wound vessel. One or more openings are provided in the body portion of the container with n appropriate closure for pumpable product to enter and exit the container. In this regard, an inlet valve (16) or other type of closure may be located at the opening in one or both of the ends of the container. Also, one or more outlet valves (18) or other type of closure are located at an opening on the body portion (12) of the container for emptying the container, for example, after HPP. The body portion 12) is composed of sufficient flexural strength and sufficient flexural modulus to enable the container to reduce in volume by from 0 to at least 30% while being rigid enough for reuse over a desired number of HPP cycles.

An apparatus and method used to maintain an engine coolant system and related components, which may be easily and quickly connected to multiple configurations and sizes, whereby an engine forward flushing can be accomplished.

The invention relates to an accessory part to be used in connection with cleaning a suction bag emptying device (13), the accessory part comprising a lid (25) for closing a container (15) in the emptying device (13), and a capsule containing agent to be used for cleaning the emptying device (13) in connection with the lid (25). The invention further relates to a suction bag emptying device (13).

Provided is a method for removing deposited solid residue from equipment used in the processing of (meth)acrylic acid or esters, including the steps of dissolving the solid residue in a cleaning solution comprising an organic carboxylic acid to produce a solid residue slurry; and removing the solid residue slurry from the equipment.
