Definitions

  • the present invention applies for example when extracting oil from an oilseed raw material or oilseed, algae, plants or more citrus.
  • thermomechanical preparation phase the raw material undergoes first a so-called thermomechanical preparation phase, followed by a pressing phase carried out in presses flat or in single-screw filters to collect more or less dry residues.
  • the residues are processed in a solvent extraction unit, conventionally n-hexane, which ultimately gives a residue with a residual liquid content varying from 1 to 3% of the weight.
  • the object of the invention is to propose a method extraction of a liquid contained in a material first, which significantly reduces the time necessary for the extraction of the liquid and therefore the energy consumption.
  • FIGs 1 and 2 there is shown schematically a continuous extraction installation of a liquid contained in a raw material, as by example an oleaginous or oleoproteinous material and especially citrus fruits, plants or algae.
  • This extraction installation consists of an extrusion machine designated as a whole by reference 1 and which comprises three parts, respectively A, B and C.
  • the extrusion machine 1 is supplied at its upstream end in raw material through an orifice 2 connected to a feed hopper 3 which is itself supplied with raw material through a storage hopper 4 and a doser 5, weight or volumetric type.
  • the first part A of the extrusion machine 1 includes two co-rotating and co-penetrating screws, respectively 10a and 10b, driven in rotation around of parallel axes, respectively 11a and 11b, inside of a first sheath 12.
  • the screws 10a and 10b are driven in rotation by an assembly, not shown, consisting of a motor, a gear motor and a gearbox.
  • the screws 10a and 10b are provided with helical threads which mesh with each other, and the inner wall sleeve 12 has two intersecting bores, respectively 12a and 12b, slightly inner diameter greater than the outside diameter of the threads of the screws 10a and 10b.
  • screws 10a and 10b are advantageously made up of fluted shafts, 13a and 13b respectively, on which are mounted screw sections.
  • each of these sections has splines corresponding to those of the shaft grooved and the external part is provided with threads helical whose pitch differs depending on the section considered for transport and processing of material first.
  • the first part A of the machine 1 is made up of several successive zones each corresponding to a particular phase of the extraction process according to the invention.
  • the screws 10a and 10b include wide threads 20 to ensure the transfer of the material introduced through the opening 2 which opens widely on the two screws 10a and 10b to distribute said material in the threads 20.
  • the screws 10a and 10b are provided with wide threads 21 to ensure mixing of the matter.
  • the sheath 12 is provided heating means 14 constituted by a circuit circulation of a heat transfer fluid or by a electric heating, for example by induction.
  • These heating means 14 make it possible to bake the material at a temperature between 90 and 150 ° C.
  • the screws 10a and 10b are provided with threads 22 with tight pitch in order to press the material to recover the liquid in this material.
  • the sleeve 12 is provided with a filtering surface formed by holes 15 distributed over a portion of the periphery of said sheath 12, rod shown in Fig. 3.
  • screws 10a and 10b are fitted with 25 threads with tight pitch and counter threads 26, that is to say reverse pitch threads comprising openings 27 extending radially from the axis of the screws to the periphery of the thread and evenly distributed around the axis.
  • the sheath 12 is provided heating means 16 constituted by a circuit circulation of a heat transfer fluid or by a electric heating, for example by induction.
  • These heating means 16 allow, in zone A5, to cook the material at a temperature between 90 and 150 ° C.
  • the second part B of the extrusion machine 1 is formed of two co-rotating single screws, respectively 30a and 30b, carried by parallel axes, respectively 31a and 31b, integral with the axes 11a and 11b of the screws 10a and 10b of the first part A of the extrusion machine 1.
  • the screws 30a and 30b are driven in rotation inside a second elongated sheath 40 with bores, 40a and 40b respectively, for each screws 30a and 30b.
  • bores 40a and 40b are independent and communicate with each other by a light 32 allowing a passage of the material between the two bores 40a and 40b sheath 40.
  • this area is formed by a first zone B1 in which the screws 30a and 30b are provided with nets 33 with wide pitch and a zone B2 in which the screws 30a and 30b are provided with threads 34 with a tight pitch.
  • Each of these series of holes 41 is characterized by its percentage of transparency.
  • This transparency is defined as the ratio of the area generated by the holes on the total interior area of a bore.
  • the third part C of the machine extrusion 1 determines a compression zone C1 and extruding the dry residue of said material.
  • This zone C1 is formed by a die 50 which includes an insert 51 cooperating with the tip of each single screw 30a and 30b and determining an air gap 52 and an outlet channel 53 of the dry residue.
  • the air gap 52 is adjustable by the insert 51 which is mounted movable longitudinally by means appropriate, not shown.
  • the residual liquid content in the residue dry coming out of the extrusion machine is less than 15%.
  • the flow rate can be used material supply, screw configuration, the speed of rotation of the screws, the configuration of the the filtering surfaces provided in the sheaths and the temperature of the heating means.
  • the material feed rate influences on the filling rate of the screws and this flow is controlled, for example, by the weight metering device 5 or volumetric.
  • the configuration of the screws determines the state of transformation of the material and by therefore the physical and physico-chemical characteristics of the product during the different phases of treatment.
  • the configuration of the single-screw influences the dynamics of pressing and the compression ratio.
  • the configuration of these screws fixes the pressing rate which is equal to the ratio of the quantity of material to be pressed contained in a thread on the time needed to perform a complete rotation of this step.
  • the screw rotation speed determines for a given flow rate, the residence time of the material within of the area considered which contributes to conditioning of this material at the entrance to the pressing zone and filtration.
  • the air gap makes it possible to create a more or less important material at the level of the sector.
  • This element therefore makes it possible to act over time of the material, but also on the time of pressing of this material within the air gap and on its degree of crushing.
  • the pressing and filtration zone by its geometric characteristics, influences the quantities of liquid extracted and on the liquid content of the residue dry at the outlet of the extrusion machine.
  • the temperature of the heating means allows regulate heat losses or heat the material also causing a change in flow within the extrusion machine, as well as within the sector.
  • Tests have been carried out on seeds rapeseed and pure rapeseed almonds 00.
  • the extrusion machine has the following configuration, for a bore diameter of 55.5mm in the first part A provided with co-rotating and co-penetrating screws and a bore diameter of 45.5mm in the second part B fitted with single screw.
  • the dry matter content in the oil collected is less than 10%.
  • the residual oil content in the meal is around 12%.
  • the extrusion machine has the configuration indicated in the table below for a bore diameter of 55.5mm in zone A with co-rotating and co-penetrating screws and a bore diameter of 45.5mm in part B with single screws.
  • the dry matter content in the oil collected is less than 10%.
  • the residual oil content in the meal is around 15%.
