Definitions

  • the invention relates to an automatic hydraulically operated press for the extraction of oils from seeds or fruit in which the ad mission and exhaust of the pressure on the different pistons, the insertion of the filter ing fabric or fabrics, the ejection of the oil cake-from the press and the setting of the press for a new cycle of operations are auto- .matic.
  • the invention consists in the filtering fabric being arranged in front of a bed for the movable pressure chamber and-in means for moving said fabric out of the pressure chamber together with the pressed oil cake. Furthermoreaccording to the invention the ram after having pressed the oil cake begins its backward motion first, and then the pressure chamber returns to its initial position, the
  • I Fig. 1 is a part elevation, part vertical section of the whole of thepress and of its accessory parts.-
  • Fig. 2 is a cross view with part-section through the casing E for one half and through the casing F for the other half.
  • Fig. 3 is avertical section of an-alternative construction of the piston-head I.
  • the apparatus comprises:
  • a frameworkA supporting a cylinder B and a bed C stayed by two columns D.
  • bis metal casing can be brought against the ressure ex- "erted, and the time during which it is apbed 0, by means of the pawns o placed symmetrically to the horizontal axis of the press.
  • the pistons H with invariable ressure tend to hold the casing E, F away rom the bed C; the action of the pistons G being more powerful when they receive the hydraulic pressure, the casing F is pressed against the bed C.
  • a pressing piston I slides inside the cylinder B, and is brought back bythe rods K connecting it with the constant pressure cylinder J sliding on the piston L when the pressure of the piston I is shut off.
  • the piston I enters the portion F of the casing to compress the material to be treated placed against the filtering fabric T itself placed next to the perforated plate Q.
  • the portion E of the casing has an inner annular perforated wall E the holes in which lead into a circular channel M conveying the liquids to a nozzle N through which theyflow away.
  • the part F of the casing cylindrical in its lower half, runs up in two parallel sides in its second half, the top part of which is open and communicates with a piping O, bringing'the parts to be pressed, the latter coming from a heater P, for instance.
  • the bed C carries a perforated plate Q, the holes in which. lead to vertical channels B which allow the liquids to escape outside the filtering casing.
  • a valve controller Z operates by cams on the pressure exhaust flapsof the pistons G and It should be noticed that the pistons H. and L are under constant pressure and only come into action when the pressure of the pistons G and I ceases.
  • the press may be doubled by fitting similar organs on both sides of the cylinder B, the latter containing in this case, two pressing pistons I opposed to each othe and moving simultaneously in opposite directions.
  • the press acts as follows:
  • the metal casing E. F. being filled with the material to be pressed, the corresl'mnding cam of the valve controller Z raises the pressure-admission flap-valve into the cyliuder B.
  • the piston I enters part F of the casing, closes the inlet of'the paste, enters part E of the casing, and there starts to strongly compress the matter.
  • the liquid runs out through the perforated wall E into the groove M and through the nozzle N into the tray A,.
  • the clutching of the pulley U allows the driving of the drum S, which pulls upwards the fabric T, thus raising the oil-cake into the funnel D,; the fabric coiling itself round the drum S tears itself away from the oilcake, the latter being maintained during its upward motion in the funnel D against the side d, tangential to the drums.
  • the oil'cake could also, by spontaneous parting from the fabric T, fall into the lower part.
  • Fig. 3 shows a different construction of part of the apparatus, the piston I being fitted with a perforated plate M the holes in which lead into vertical channels thence into a circular groove N,, from which the liquids flow out of the casing, by way of the pipe 0,.
  • the fabric L will resume its position by its own weight, as the fabric T returns into position.
  • an automatic hydraulically operated press for extraction of oil from seeds and fruit, a ram, a movable pressure chamber for said ram, a bed for the pressure chamber carrying a perforated plate allowing liquid to escape from the pressure chamber, a filtering fabric arranged in front of the perforated plate of the bed, means for moving said fabric to and fro upwards anddownwards and from out of the pressure chamber, hydraulic means for moving said ram into the pressure chamber and withdrawing the fabric to be pulled upwards togetherwith the adhering oilcake, and means for controlling the motion of the fabric and giving it but once the to and fro motion only after the pressure chamber being removed from its bed. 7
  • a ram In an automatic hydraulically operated press for extraction of oil from seeds and fruit, a ram, a movable pressure chamber for said ram, a bed for the pressure chamber, carrying a perforated plate allowing liquid to escape from the pressure chamber a filtering fabric arranged in front of the perforated plate-of the bed, means for moving said fabric to and fro upwards and downwards and from out of the pressure chamber, hydraulic means for moving said ram into the pressure chamber and withdrawing from the latter, hydraulic means for moving the pressure chamber to and fro, an inlet opening for material to be pressed provided in the wall of the pressure chamber and to be controlled by the ram, means for admitting the hydraulic pressure onto the ram and onto the pressure chamber in such a way that the ram after having pressed the oil cake begins its backward motion first and then the pressure chamber is returning to its initial position whereby the speed of the pressure chamber exceeds the speed of the ram, thus enabling the fabric to be drawn u, awards together with the adhering oilcake, and means for controlling the motion of
  • a ram having at its front end a perforated plate for the escape of liquid, a filtering fabric having one edge, attached to the upper part of the front surface of the ram and laying against said front surface, a movable pressure chamber for said ram, a bed for the pressure chamber, carrying a perforated plate allowing liquid to escape from the pressure chamber, a second filtering fabric arranged in front of the perforated plate of the bed, means for moving said second fabric upwards and from out of the pres sure chamber, hydraulic means formoving said ram into the pressure chamber and with drawing from the latter, hydraulic means for moving the pressure chamber to and fro, an inlet opening for material to be pressed pro viding in the wall of the pressure, chamber and to be controlled by the ram, means for a dmitting the hydraulic pressure onto the ram and onto the pressure chamber in such a way that the ram after having pressed the oil cake begins its backwards motion first and then the pressure chamber
