A cleaning process is provided after the food processor completes food processing, and in the cleaning process, cleaning water, the volume of which is no less than V0, is injected into the cup body at least twice, and the crushing device is controlled to drive the cleaning water to move in the crushing cavity, wherein 0.2V1≤V0≤0.6V1. The food processor can realize self-cleaning, and the crushing efficiency is high.

To simplify management of a sterilization process of a filling nozzle, a method for sterilizing a filling nozzle is provided, hot water or a liquid chemical agent is fed to drink supply piping that feeds a drink to a plurality of filling nozzles at the same time, the hot water or liquid chemical agent is discharged from all the filling nozzles, a flow rate of the hot water or liquid chemical agent is detected at all the filling nozzles, a representative temperature of the hot water or liquid chemical agent upstream or downstream of at least one filling nozzle is measured, and the sterilization process is ended when both the flow rate at each filling nozzle and the representative temperature reach respective target values.

A mobile decontamination system has an internal combustion engine, a generator, a first pump, a boiler and a second pump. The engine is coupled to the generator and to the first pump. The first pump is designed for discharging a first decontamination medium via a first spray lance. The second pump is designed for discharging a second decontamination medium via a second spray lance. A system controller is designed for selectively operating the first pump and the heating boiler in one of at least two different operating modes. In the first operating mode, the first pump delivers a first volumetric flow through the boiler which is at such a high level that the first decontamination medium is in liquid form. In a second operating mode, the first pump delivers a second volumetric flow through the boiler which is at such a low level that the first decontamination medium transfers into gaseous form.

A sterile tube connector for a fluid circuit system comprising a housing. A first opening is configured to receive a first length of tubing in communication with a first chamber. A second opening is configured for communicating with the first chamber when the tube connector is in an open configuration but not in a closed configuration. The second opening is configured to reversibly engage a third opening to form a second chamber. The third opening is configured for communicating with a second length of tubing. A first portion of the housing forming the first opening comprises a material at least partially permeable to a sterilization energy source for sterilizing contents of the second chamber.

An embodiment of the present subject matter including a FOUP body and a FOUP cover includes: a loading and unloading part configured to load or unload the FOUP; a standby part which is provided at one side of the loading and unloading part and on which the FOUP body and the FOUP cover are separated from or coupled to each other; a cleaning chamber configured to clean the FOUP body and the FOUP cover using steam; and a robot configured to transport the FOUP body and the FOUP cover between the standby part and the cleaning chamber.

Vehicle washing apparatus has a platform for supporting a vehicle and a filtering grid covering the platform. A hopper under the grid receives a combination of water after its use in washing the vehicle and waste removed from the vehicle surface by the washing. Larger solid matter is retained on the grid. The fluid combination is pumped from the bottom of the hopper to a clarifier having another hopper. Another pump is used to pump bottom-lying residue from the other hopper into a separator bag formed of mesh material permitting drainage of water from the separator bag into the clarifier while maintaining solids within the separator bag.

The present invention relates to a method of removing contaminants from interior of a vehicle. The contaminants become suspended by an emulsification process and removed from the interior of the vehicle by a vacuum suction unit.

The present disclosure relates to cleaning a surface in a printing device, wherein a guiding member directs a stream of cleaning fluid towards the surface; and at least one barrier unit to confine the stream of cleaning fluid to a portion of the surface, wherein the at least one barrier unit guides air to provide at least one air curtain confining said stream of cleaning fluid to the portion of the surface.

A low-pressure system for cleaning items includes a tub, an ultrasonic generator and ultrasonic transducer, at least one steam head mounted in the tub having a rotatable nozzle configured to direct steam towards the bottom of the tub. The steam generator is in fluid communication with both the first steam head and the second steam head. A valve including a foot pedal mounts in fluid communication between the steam generator and each steam head. The steam generator connects to a water and power source for generating dry steam at a temperature exceeding 300° F. and at a pressure of less than 150 psi. The dry steam maintains a dryness fraction of 0.4-0.9 at all points within the system.

A handheld appliance for emitting steam to treat a fabric has a housing, a water reservoir, a pump, and a steam generator operatively connected to the pump. The housing has an annular steam emitting head having a hole passing through the steam head. The steam head has an outlet with a shape surrounding the hole so that steam inside the steam head is emitted out of the steam head through the outlet around the hole. A handheld appliance for emitting steam to treat a fabric also has a housing having a water reservoir, a pump, a steam generator operatively connected to the pump, and an outlet. The steam generator forms a steam path that has a first layer that extends from an inlet into the steam generator on a first side of a heater to a second layer that is on a second side of the heater opposite to the first layer.
