Definitions

  • the present invention relates to the production of meslins and flours commencing with various vegetable products such as, for example, cereals or legumes.
  • the present invention has as one object to provide an apparatus in the form of a mill, retaining the principle of the millstones, and permitting domestic or dietetic centre utilisation for the milling of various vegetable products utilised in dietetics, in proportion according to needs, whilst thus preserving all their properties.
  • the mill is more particularly characterised by great speed of relative rotation of the millstones, and by low inertia.
  • the mill comprises, on the one hand, a certain number of arrangements ensuring the cooling of the motor, the protection against the possible breaking of the rotary millstone, and the filtration of the air, and, on the other hand, a system for moving the millstones nearer together and further apart, and, finally, an arrangement for the forced discharge of the meslins.
  • the passage for the grain comprises an opening which is regulatable by means of a regulating screw or by any other analogous regulating arrangement.
  • FIG. 1 is a view half in external elevation and half in sectional elevation of a mill in accordance with the invention
  • FIG. 2 shows a device for the reception of the meslins and for the evacuation of the air
  • FIG. 3 is a view in section of a bolter for the separation of the meslins according to three different size grades
  • FIG. 4 is a view half in external elevation and half in sectional elevation of the upper portion of the mill with the screw for regulating the opening of the passage for the grain, and
  • FIG. 5 is a view of a detail, in plan, of the opening for the passage of the grain.
  • the mill which is the subject of the invention, is comprised essentially of a casing including an upper cylindrical body 1 supporting a hopper 2, and a likewise cylindrical lower support 3. Within the casing is an upper millstone 4 fixed in a rigid manner in the body 1, a rotating nether millstone 5 secured upon the shaft of a motor 6 mounted in the support 3, and two fans 7 and 8. An outlet spout 9 to which is attached a bag 10 or analogous receptacle projects laterally from the casing.
  • a ventilation chamber 12' serving for the cooling of the motor 6 by virtue of the fan 8 drawing the air through a filter 14 fixed, for example by means of two rails 15, below the base 11, and through openings 16 provided in the base 11.
  • the support 3 comprises a connecting piece 17 furnished at its upper extremity with an internal screw threading 17' co-operating with an external screw threading l of the body I.
  • the relative displacement between the body 1 and the connecting piece 17, or the support 3 when the latter co-operates directly with the body 1, determines the spacing between the two millstones 4 and 5 and thus the grade or size of the meslins. From this it follows that in order to obtain the necessary precision the screw threading connecting the connecting piece 17 and the body is of the micrometric type.
  • a locking system for example in the form of a screw 18.
  • a second air filter 19 Between the upper part of the motor 6 and the rotary nether millstone 5 there are provided a second air filter 19, a plate 20 for locating the filter l9 and provided with holes for the passage of the air, and a second fan 7, which discharges towards the outlet spout 9 and towards the bag 10 which is fixed there to receive the meslins produced by the two millstones 4 and 5.
  • the current of air created by the fan 7 around the base of the millstones 4 and 5 obviates the accumulation of the meslins and the clogging of the millstones.
  • the supplying of grains to the mill is effected at the upper part of the hopper 2.
  • the fixed upper millstone 4 comprises a central passage 22 comprising a channel 3 through which the grains descend vertically in order to arrive by natural gravitation at the nip between the millstones 4 and 5.
  • the rotary nether millstone 5 supports at its upper part a hollow stem 23 extending inthe central opening of the fixed upper millstone 4 and furnished with a screw threading 23 for disengagement, that is to say of the opposite sense in relation to the sense of rotation of the millstone 5.
  • the stem 23 terminates, suitably, at its upper end in the form of a stirring vane 24 serving for the agitation of the grains in the hopper 4.
  • the invention has as another object and according to another feature of the invention an evacuating arrangement disposed between the outlet spout 9 and the reception bag 10 (FIG. 2).
  • This evacuating arrangement is advantageously comprised of a three-way connecter 25 of which one passage is connected to the outlet spout 9, a second passage is connected to the bag 10 for the reception of the meslins, whilst the third passage, upwardly directed, is equipped with a very fine mesh filter permitting the escape of the air whilst the meslins become deposited in the bottom of the bag 10, which in this instance may be completely airtight.
  • outlet spout 9 of the mill may be equipped with a bolter permitting the separation of the different size grades of the meslins.
  • this bolter or separating arrangement is constituted by a chamber 26 divided into compartments by partial partitions 27 equipped with deflectors 28 and provided at its base with secondary outlet spouts 29 to which are fixed the sacks 10 or receptacles, possibly with the interposition of an obtura-.
  • tor filter with a double bottom which permits, by rotation for regulation of the evacuation of the air as desired, either progressively or by all or nothing.
  • the outlet spout 9 of the mill or an intermediate outlet spout 10 may, in the case of the application of the bolter, be equipped with a throttle vane or rotary accelerator 30. 2
  • the chamber 26 may comprise regulatable obturator air filters 31 in its upper portion. According to the regulation of the obturators it is therefore extremely simple to obtain the separation of the different size grades of the meslins as a function of their densities.
  • the channel 22 for the passage of the grain is regulatable by means of a screw 32 the inner end of which thus serves as a shutter.
  • This latter screw 32 is provided with a knob 33 easily accessible from the exterior and permitting a good prehension.
  • the regulation of the opening of the channel 22 for the passage of the. grain can be effected as a ⁇ function of the flow quality of the grain and. of. the speed of milling desired.
  • graduation marks 34 may be engraved and coloured with reference tothe grains and the speedsof milling utilised, upon thescrew
  • the screw 32 for regulating the supply does not come into engagement with the hollow stem-23
  • a mill for the production of meslins and flours comprising a fixed annular upper millstone and a rotatable lower millstone, said millstones having a common vertical axis, a casing supporting said upper millstone,
  • a mill as claimed in claiml said electric motor being of the rotary type and having an output shaft that rotates about a vertical axis coaxial with said mill-.
  • said fan means including a fan coaxial with and disposed below said motor for drawing air into the bottom of said casing.
  • a mill as claimed in claim 1 and filter means for air passing between the interior of said casing and said chamber.
