Food product can be selectively drained or retained in food flow path, wherein the self-cleaning valve can be continuously or intermittently exposed to a treating solution for treating non-food flow path portions of the self-cleaning valve assembly.

An endoscope reprocessor includes: an endoscope housing portion; a medicinal solution tank in which a medicinal solution is stored; a medicinal solution transfer portion that transfers the medicinal solution from the medicinal solution tank to the endoscope housing portion; a comparison portion that compares the concentration of the medicinal solution and a first reference concentration; a first adjustment portion that increases a reaction rate of the medicinal solution in a state in which the concentration of the medicinal solution is lower than the first reference concentration; and a control portion to which the comparison portion and the first adjustment portion are connected, and which drives the first adjustment portion in a case where the comparison portion determines that the concentration of the medicinal solution is lower than the first reference concentration.

To simplify management of a process of sterilization of a filling nozzle.

In a method for sterilizing a filling nozzle, hot water or a liquid chemical agent is fed to drink supply piping (7) that feeds a drink to a plurality of filling nozzles (2a) at the same time, the hot water or liquid chemical agent is discharged from all the filling nozzles (2a), a flow rate of the hot water or liquid chemical agent is detected at all the filling nozzles (2a), a representative temperature of the hot water or liquid chemical agent upstream or downstream of at least one filling nozzle is measured, and a sterilization process is ended when both the flow rate at each filling nozzle and the representative temperature reach respective target values.

A machine for cleaning regeneration chambers of furnaces, the regeneration chambers having stacks of hollow refractory elements delimiting vertical passages, which define chimneys includes a self-propelled support structure to be introduced into a compartment, below the regeneration chamber to be cleaned, which communicates with the regeneration chamber. The machine further includes at least one lance, applied to the self-propelled support structure and configured to send within the vertical passages a stream of cleaning material powder and compressed air generated by a compressor positioned outside of the regeneration chamber to be cleaned, and at least one suction mouth, applied to said support structure and configured to suck cleaning material dust and aspirable materials from the ground, which were removed during the cleaning operation. At least one video camera is mounted on the support structure and at least one monitor controls from outside, through the video camera, operation of the machine.

Disclosed herein is a cleaning ammunition for facilitating cleaning of a projectile launching system, in accordance with some embodiments. Accordingly, the cleaning ammunition may include a casing and a cleaning projectile. Further, the casing traversable through a barrel of the projectile launching system. Further, the casing may include a proximal end and a distal end. Further, the casing may include a propellant disposed within an interior space of the casing at the proximal end. Further, the casing may include a primer disposed alongside the propellant. Further, the primer is configured to ignite the propellant based on a striking force receivable from a launching mechanism of the projectile launching system. Further, the cleaning projectile disposed within the interior space adjacent to the propellant. Further, the cleaning projectile is disposed at the distal end of the casing. Further, the cleaning projectile may be configured for performing a cleaning action on the barrel.

A clean-in-place process may begin with a pre-rinse step in which soil (e.g., contaminants, residual product) is flushed from industrial equipment prior to circulating a cleaning agent through the equipment. To determine when the equipment has been suitably flushed, pre-rinse fluid exiting the industrial equipment and containing soil may be fluorometrically analyzed. A concentration of the soil is determined from fluorescent emissions emitted by the soil itself. Based on this information, the pre-rinse flushing process can be controlled, for example, to minimize water usage, maximize pre-rinse cleaning, or based on any other suitable metric.

A portable resonance induction cleaning system for cleaning a process tubular or heat exchanger can include a portable high pressure plunger pump, which can provide a liquid to the portable resonance induction cleaning apparatus. The portable resonance induction cleaning apparatus can regulate flow of the liquid to provide pressurized pulses of the liquid with a resonance for removing fouling. A hose assembly or ram connecting mechanism can provide the pressurized pulses of the liquid to the process tubular or heat exchanger. Air can be used to control flow of the pressurized pulses of the liquid. A hydraulic intensifier can be in fluid communication with the portable resonance induction cleaning apparatus for receiving the air, and a hydraulic control valve can be bi-directionally engaged with the hydraulic intensifier and the hydraulic ram. The hydraulic ram can seal with the heat exchanger to provide the pressurized pulses of the liquid thereto.

A flushing station for a ring-pipe or series-pipe system, comprises a cold water port for connecting a cold-water pipe, a hot water port for connecting a hot water pipe, and a waste water port, wherein the cold-water port and the hot water port are fluidicly coupled to the waste water port. The cold-water port, the hot water port and the waste water port are assigned to a bottom side of the flushing station.

An endoscope reprocessor includes: a connector to which an endoscope is connected; a fluid supplying section that supplies fluid to the connector; an electromagnet arranged at the connector and including a magnetic material and a coil wound around the magnetic material; a current supplying section; a magnetic force switching portion configured to switch a strength of a magnetic force to at least one of a first strength and a second strength weaker than the first strength; and a control section configured to switch the strength of the magnetic force by controlling the magnetic force switching portion while driving the fluid supplying section.
