The apparatus comprises: a vessel including an opening, and an uptake line or pump coupled to the vessel and configured to transport the contained and suspended materials from an interior of the vessel to an exterior of the vessel.

An assembly rod (9a) is provided extending into the fermentation mass in the fermentation tank interior from the service shaft and at a distance from the tank wall (12).

A conveying system (206) can displace the articles (204) to be treated towards the dip-coating tank (202), into the inner edge of the dip-coating tank (202), out of the dip-coating tank (202) and away therefrom.

It is really inside ourselves that the cleaning process is taking place.

Each nozzle is oriented toward an interior space of the desalter vessel and is arranged oblique to the piping circuit.

Pulp stock (M) is guided to an inlet pipe (11) of the deaeration tank (10) and via it to the inner space of the deaeration tank (10) which space comprises a collecting space (V1) for the pulp stock (M).

The agitation means comprises a drum (20), which is rotatably arranged inside the pressure vessel (2) and which has an inner space (21 ) for receiving material that is introduced into the pressure vessel.

The width from the center of the agitating shaft is brought so close as possible to the internal diameter of the agitating container, thereby to leave substantially no clearance.

A nuclear reactor includes a reactor vessel, a containment vessel that surrounds the reactor vessel, and a condenser that receives coolant from within the reactor vessel.

The service shaft is arranged on a tank roof covering the fermenter tank interior in a manner which seals the tank roof.

As a result the laundry machine may improve capacity of the tub (100, 120, 130) and to prevent collision between the drum (300, 320, 340) and the tub (100, 120, 130) by adjusting the pressure inside the tub (100, 120, 130).

The liner is chemically inert and resistant to the one or more reactants to be contained inside the liner and the liner has at least one opening in communication with the inside of the liner.

A guiding device (30) is mounted and extended from one side of the upper portion of the tank body (10) toward the opposing side of the lower portion of the tank body (10) for guiding the falling down container to slide down and toss over.

Flow modifier members are placed such that their larger surface is more aligned with the larger dimension of the interior volume of the vessel in which the member is placed.

The washing and dewatering tub (4) is rotatably installed inside the water tank (3).
