Description »

The subject of the present application is a screening machine known Sauart, the one from a task - or Einüttrumpf and a subsequent. The sieve space consists of · The bottom of the insertion trunk forms in a known manner a screw trough with a motor-driven screw shaft, the hull between rubble and Siebrauni . passes through and for holding the screen wing support crosses in the sieve space, is extended

The sieve device in. Sieve space is in cooperation of afore-mentioned wing mechanism and a fixed screen mesh cylinder formed and fed by the tendon

With a large capacity, the heap of the flour filling must have as moderate a height as possible from the service floor to the pouring edge fuselage lower edge za. lie koamt · The auger sits on the vane shaft of the sieve and runs at its high number of revolutions. The outer screw diameter is very small compared to the sieve diameter, so that the sieve box enclosing the sieve extends down below the upper edge of the service floor »

If the rubble box is then on the floor , the built-on sieve box penetrates a corresponding breakthrough in the floor.

This arrangement of the machine is one of those that need to be protected Objects of the registration because it represents the basis necessary for the increased working capacity of the machine

These sieving machines are used to prepare baking flour loosened up and cleaned. They become whole by emptying them Sacks of flour are filled into the bulk trumpet by hand and then the whole filling should be done automatically and completely without fiest and without loosen up further operation, guide through the sieve cover and discharge

This works easily with well-stored dry flours, but moist flours tend to be in the bulk trumpet above the auger to form a bridging semi-consistent mass. Under the aehlbrücke that forms, the snail then continues to run empty and the screening process remains interrupted as long as it is not in the bulk trumpet

poking or shaking causes the flour bridge to collapse

Such behavior of the damp flour in the sieving machine excludes an automatic tooth sieving of the Schüttrumpfüll, which means an increase in the price of the bakery, because Such a flour sifting requires additional labor

Another object of the present invention is a mechanically moved in the bulk hull just above the Loosener shaft provided with crank-like arms, the ends of which are connected with guide rods · These crank arms and guide rods cut through the entire length of the rubble hulls it continuously the amount of flour stored or bridging over the screw and thereby tear the connection between the measuring particles continued on »

Sin is an automatic sieving process for the entire poured quantity secured here by, and one worker saved

The cylinder sieve of the present invention is closed off at the rear end of the sieve box by a metal, removable cover carrying a shaft bearing, into which the ends of the sieve blades protrude, and which has passed away with a tangential and helical discharge nozzle connected to the direction of rotation of the sieve shaft ühreiniichkeiten circuits therein with the signal generated by the Siebflügeln Zentrifugalluftstroni by means of which they are blown out by prescribed Äustragstutzen from the Siebinnern · D _e r prescribed IÖ & ckel are to Losnäbme the entire screening space freely, the worm shaft so Cap work exposed for insertion or removal is ·

The machine device to be protected is enclosed Drawing shown schematically.
