A reconditioning apparatus for an endoscope including a controller configured to: supply an interior of the endoscope with a fluid at a predefined pressure; supply one or more channels of the endoscope and an exterior of the endoscope with a rinsing liquid to carry out a reconditioning process using the rinsing liquid; concurrently with the supplying of the rinsing liquid, determine a temperature and a pressure in the interior of the endoscope during the reconditioning process; and when the determined pressure decreases lower than a predetermined pressure: identify the endoscope as not defective, when the decrease in the determined pressure is preceded by a corresponding decrease in the determined temperature, and identify the endoscope as defective, when the decrease in the determined pressure is not preceded by a corresponding decrease in the determined temperature.

The present disclosure is a food injection needle cleaning system and method. The food injection needle cleaning system comprises a cleaning fluid tank coupled to high-pressure pump configured to pump cleaning fluid through at least one inlet, a channel, and at least one outlet of a food injection needle to dislodge and remove debris as well as sanitize the needle. The present disclosure comprises a high-pressure chamber configured to secure the food injection needle and seal around the needle such that fluid enters the needle through an inlet of the high-pressure chamber and exits the needle through a waste line.

A method and an apparatus for cleaning a channel, especially a transmission and/or cooling channel, in any type of device, machine, installation, and/or tool, particularly in any type of heat exchanger and/or a molding core, cavity and/or insert is proposed, wherein a channel is cleaned through dynamic, bi-directional pulsation of cleaning medium inside the to-be-cleaned channel, the method being realized by a cleaning apparatus equipped with a diaphragm pump module, plugged either only in the feed side of the transmission line or in the feed side and in the return side, which, after connecting the diaphragm pump module to the external energy source and shutting off the flow control system from the reservoir and the feed pump, allows for putting cleaning medium into a state of two-way dynamic pulsating motion.

The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

The present invention relates to an apparatus (20) for clearing a plugged control line (12), in particular for clearing a plugged surface controlled sub-surface safety valve (11) control line (12), the apparatus (20) comprising a connecting means (27) configured to connect the apparatus (20) to an upstream end of the plugged control line (12); and a pumping means (21, 22) configured to pump a dissolvent (30) through the connecting means (27) into the control line (12) to build up dissolvent pressure in the control line (12). The invention further comprises a bore system and a method for clearing a plugged control line (12).

A method of cleaning and sterilizing a drink filling apparatus including a CIP process of circulating a cleaner in a drink supply piping to remove foreign matter on an interior of the drink supply piping, and an SIP process of sterilizing the interior of the drink supply piping. The processes are performed at the same time or in sequence without an interruption between the two. The SIP process uses the cleaner to sterilize the interior of the drink supply piping. After the SIP process, while the cleaner is kept circulating, a temperature condition at a predetermined position in the drink supply piping is adjusted to a temperature setting for manufacture, after which the cleaner in the drink supply piping is removed.

An apparatus and process to clean medical devices, such as endoscopes, that includes an automatic endoscope reprocessor system equipped with a peracetic acid/hydrogen peroxide sensor are described.

A cleaning system comprise: a first pipe 20 connected to a reactor 10 used for producing polysilicon by using chlorosilane as a raw material; a heat exchanger 30 connected to the first pipe 20; a second pipe 60 provided between the heat exchanger 30 and the first pipe 20; and a driving unit 50 provided at the first pipe 20 or the second pipe 60. A cleaning liquid circulates through the first pipe 20, the heat exchanger 30 and the second pipe 60 by the driving unit 50.

A high temperature food treatment method is disclosed wherein by alternatingly operating between a first final heater (13) and second final heater (23) arranged in parallel on a food processing line (30, 40, 50), it is possible to operate a continuous process, yet significantly reducing the overall downtime of the processing line (30, 40, 50), by performing a cleaning in place process on the final heater (13, 23), not currently being used in the high temperature food treatment process, thereby eliminating or significantly reducing the influence on the processing line (30, 40, 50) downtime by the process elements and/or processing equipment most easily contaminated.

A vehicle fluid exchange machine is disclosed that allows the technician to control the flow into the vehicle or stand-alone cooling or hydraulic system either manually or automatically based on a safe working pressure for the vehicle. If the vehicle's cooling system can handle a higher pressure for example, the technician may adjust the machine's flow to a flow rate consistent with the higher pressure rating while monitoring the pressure across the system. The default setting for the air injection process is automatic, but can also be switched to manual by the technician.
