Claim 3

An apparatus for preparing a dough-like material from a powdered material mainly consisting of a starch-containing powder, thickening agents and binders, to which a liquid, preferably water, is added, said dough-like material being destined for the manufacture of so-called potato fries, croquettes and similar fried products, said apparatus comprising a feeding device for feeding a stream of said powdered material into a mixing device and a feeding device for feeding a stream of liquid into said mixing device, said mixing device having an outlet portion dispensing the mixture of powdered material and liquid in liquid state to a container in which said mixture stiffens to a dough-like material, said feeding device for the liquid including a water reservoir having a movable means movable between two predetermined positions, said water reservoir having a supply line adapTed to be connected to a water main and including a magnetic valve, and having a line operating a level switch, and a line connecting said reservoir of said feeding device for water to a common supply channel, said latter line including a valve, said movable means and said line to said level switch cooperating with each other such that during operation at the lowest position of said movable means said magnetic valve in said line connected to the water main is opened, and at the highest position of said movable means is closed.

Claim 4

An apparatus for preparing a dough-like material from a powdered material mainly consisting of a starch-containing powder, thickening agents and binders, to which a liquid, preferably water, is added, said dough-like material being destined for the manufacture of so-called potato fries, croquettes and similar fried products, said apparatus comprising a feeding device for feeding a stream of said powdered material into a mixing device and a feeding device for feeding a stream of liquid into said mixing device, said mixing device having an outlet portion dispensing the mixture of powdered material and liquid in liquid state to a container in which said mixture stiffens to a dough-like material, said feeding device for the liquid including a water reservoir having a movable means movable between two predetermined positions, said water reservoir having a supply line adapTed to be connected to a water main and including a magnetic valve, and having a line operating a level switch, and a line connecting said reservoir of said feeding device for water to a common supply channel, said latter line including a valve, said movable means and said line to said level switch cooperating with each other such that during operation at the lowest position of said movable means said magnetic valve in said line connected to the water main is opened, and at the highest position of said movable means is closed.

Claim 6

An apparatus for preparing a dough-like material from a powdered material mainly consisting of a starch-containing powder, thickening agents and binders, to which a liquid, preferably water, is added, said dough-like material being destined for the manufacture of so-called potato fries, croquettes and similar fried products, said apparatus comprising a feeding device for feeding a stream of said powdered material into said mixing device and a feeding device for feeding a stream of liquid into said mixing device, said streams of liquid and powdered material being fed into an inlet portion of said mixing device, said mixing device having an outlet portion dispensing the mixture of powdered material and liquid in liquid state to a container in which said mixture stiffens to a dough-like material, said mixing device being provided at its said inlet portion with a vertical feeding channel for feeding the streams of liquid and of powdered material commonly into said inlet portion of said mixing device, said vertical feeding channel being provided with means for feeding the stream of liquid in the shape of a sleeve therein and with means for feeding said stream of powdered material through the interior of said liquid sleeve into said mixing device.
