Abstract: Ambient water and steam in a predetermined ratio are delivered into the entrance of a venturi chamber in a fluid accelerator. The steam condenses and in so doing elevates the water temperature significantly. The heated water passes through a venturi throat and then has its pressure elevated considerably above the pressure of the incoming steam prior to discharging from the accelerator into valved piping leading to cleaning spray headers on opposite sides of the moving metal strip. High pressure, high temperature water cleaning sprays are directed through header nozzles onto the strip to thoroughly clean its entire surfaces. Venturi vacuum is utilized whenever desired to draw a cleaning additive into the system where such additive is entrained in the water stream. Simplicity and economy are achieved in a highly efficient cleaning system.

Abstract: In packing machines of the kind which form a tube of packing material for subsequent conversion into separate, filled packages, a filler pipe for the contents is usually arranged inside the material tube. Especially when the packing machine works with foodstuff under sterile conditions, the filler pipe as well as other machine parts situated inside the tube have to be carefully cleaned before and after production. As the filler pipe normally is surrounded by the foodstuff in the tube, it will have to be cleaned on the outside as well as the inside, and to facilitate the cleaning it is suggested to use a cleaning container, which has a controllable outlet and surrounds the lower end of the filler pipe and makes cleaning by circulation of a cleaning liquid possible. To increase the cleaning effect the cleaning liquid is circulated through the filler pipe as well as through separate nozzles directed towards the outside of the filler pipe.

If the temperature is below transformation after descaling the steel body is reheated without new scale formation before passing to accelerated cooling. Cooling water and surface quality are thereby improved.
