FR2501008A1 - Bakery dough dividing machine producing loaf dough pieces - by pressure feeding dough into mould cavity of depositor roll - Google Patents

Abstract

Bakery dough dividing machine is for producing a series of dough pieces, all of equal vol., for making loaves of bread. The machine comprises a cylindrical roll which is rotated about its axis. In its circumferential surface, the roll has an open mouthed mould cavity of vol. equal to that of a dough piece. At one stage in the course of each revolution of the roll, the mould cavity is located briefly in communication with the outlet of a dough supply hopper. At this stage, dough is transferred under pressure through the hopper outlet into the mould cavity. To obtain this pressurised transfer, the dough hopper is pref. a closed vessel into which compressed air, etc. can be supplied to drive dough towards the outlet. When the roll has rotated to bring the filled mould cavity to a depositing position, compressed air is pref. injected through the base of cavity to free the dough piece and eject it cleanly from the cavity. The hopper is pref. the rotary bowl of a dough kneading machine operating inside an air-tight chamber. Used in prodn. of dough pieces for making loaves of bread. Positive transfer of dough from kneading bowl into mould cavity and clean demoulding of dough piece from dividing machine mould cavity are obtd. Very compact, hygienic and trouble-free combination of kneading and dividing operations is obtd.

Description

a) MIXER WITH AUTOMATIC DRAIN, distribuetrur.

b) The present invention relates to all kneaders and mixers
with the advantage of emptying without manual intervention, and
orientation to another place or machine as in the
patent n0? 925O4 supplemented by the AUDITIVE dated 4/19 19bu

c) Currently there is no identical machine:
1) known kneaders and mixers are not entirely

) They do not empty ONLY the baker or the staff of
service must empty the tank by hand.

3) It is therefore necessary by hand to transport the dough to places where my

The invention therefore achieves at least a gain of a function,
plus a significant gain in fatigue and handling.

conventional mixers fitted with removable bowls, these
being handled empty or full BY HAND,
Always by hand they are pushed to be taken in
load by tilting elevators of complete tanks

This process, besides being very expensive, is indisputable
danger of unsecurity for staff in service

this invention does three things well: rsalaxage, draining
and transport automatically.

This so-called positioned stop device then allows the actuator (15) to open the shutter (16) by pushing. The tank (7) is then with the lower part open, the upper part under air pressure the tab or the product under the effect of its own weight plus the pressure flow directed by the chute (17) on the lower conveyor belt.

The latter is driven by a small reduction motor (18).

When all the dough is entrained by the belt and is left of the tank, the pressure inside it

The control unit (4) then controls the cylinder (20) which CLOSES the shutter and also returns to its starting position. The machine is ready to cycle again. If you want to clean assuming the job is finished , note the presence of a safety device when the cover is removed, or more exactly when the machine is open.

It is obvious that the evacuation conveyor can be coupled with another elevator or conveyor conveyor to take the dough or the product to another place at the desired distance and height by means of a simple material inexpensive and safe for personnel. on duty.

Claims (1)

CLAIMS, MACLIINE allowing to knead or knead a product, then to evacuate it from the vat without manual intervention; when the dough is mixed, or the homogeneous mixture rereads. Characterized in that it includes: a) - A rotating tank with a lower drain orifice. This rotating tank is located IN b) - A fixed tank with watertight closure. c) -A mechanical stirring system whose shaft is fixed  tightly in the upper part of the tank  fixed. d) -A means of pressurizing the interior of the system. e) -A special shutter placed at the lower orifice  of the rotating tank.  f) -A micro-process control center or relay  timer for performing all operations  necessary for the preparation of the product and works  automatic machine as desired  The set makes it possible to carry out all of the ope  rations once the programming has been established according to  products to be mixed and the result to be obtained.
