Abstract
Apparatus (10) for processing organic material is disclosed which breaks down the inedible components of fruit and vegetables (core, skin, pips, pithy material) into an edible substance with a cream-like consistency. The apparatus comprises a passage having a series of communicating sections including at least a first section and a second section, with each sections having an inlet end and an outlet end and at an angle with respect to the section which precedes it, and an impact wall at the outlet end of each section, means for pressurising the material so that, in use, the material flows into the inlet end of the first section of the passage, emerges from the outlet end of the first section, impacts on the impact wall at the outlet end of the first section, changes direction and then flows into the second section. The apparatus comprises a first part that defines surfaces and a second part that defines surfaces corresponding to the surfaces of the first part, with the passage being formed between the corresponding surfaces of the first and second parts. The apparatus further comprises a bias mechanism that urges the second part towards the first part. The means for pressurising the material comprises a pressure chamber which forms a continuation of a cylindrical bore of a barrel, the pressure chamber communicating with a passageway and having a piston in the cylindrical bore, means for reciprocating the piston in the cylindrical bore in alternating forward pressurising strokes and retraction strokes so that material is forced by the forward pressurizing strokes of the piston from the cylindrical bore, directly through the pressure chamber and the outlet of the pressure chamber, towards the passageway.
Claims (15)
1. An apparatus for processing materials, said apparatus comprising a passage having a series of communicating sections including at least a first section and a second section, each of said sections has an inlet end and an outlet end and each of said 5 sections is at an angle with respect to the section which precedes it, an impact wall at the outlet end of each section, means for pressurising said material so that, in use, the material flows into the inlet end of the first section of said passage, emerges from the outlet end of the first section, impacts on the impact wall at the outlet end of the first section, changes direction and then flows into the second section; 10 said apparatus comprising a first part that defines surfaces and a second part that defines surfaces corresponding to the surfaces of the first part, said passage being formed between said corresponding surfaces of the first and second parts, and said apparatus further comprising a bias mechanism that urges the second part towards the first part; 15 wherein the means for pressurising the material comprises a pressure chamber which forms a continuation of a cylindrical bore of a barrel, said pressure chamber communicating with a passageway and having a piston in the cylindrical bore, means for reciprocating the piston in the cylindrical bore in alternating forward pressurising strokes and retraction strokes so that material is forced by the forward pressurizing 20 strokes of the piston from the cylindrical bore, directly through the pressure chamber and the outlet of the pressure chamber, towards said passageway.
2. n apparatus as claimed in claim 1, wherein said sections are at right angles to one another.
3. An apparatus as claimed in claim 1 or 2, wherein the first part comprises a sleeve with an internally stepped bore to provide alternating axially facing surfaces and radially inwardly facing cylindrical surfaces the diameters of which increase from one end of the internally stepped bore to the other, and wherein the second part comprises a bobbin which matches the shape of the internally stepped bore and has axially facing surfaces alternating with cylindrical surfaces, the diameters of the cylindrical surfaces increasing from one end of the bobbin to the other, there being an annular gap between each cylindrical surface of the bobbin and the cylindrical surface of the sleeve which lies 5 radially outwardly of it.
4. An apparatus as claimed in claim 3, wherein the widths of the annular gaps decrease in the direction from the smaller end of the sleeve and bobbin towards their larger ends. 10
5. An apparatus as claimed in claim 3 or claim 4, wherein the bias mechanism comprises means selected from a spring or a hydraulic cylinder.
6. An apparatus as claimed in any one of claims 3 to 5, wherein the bobbin has a sealing element at its smaller diameter end which fits into an outlet end of a 15 passageway that leads from the outlet of the pressure chamber, said sealing element, in one of its positions, sealing said outlet end of the passageway.
7. An apparatus as claimed in any one of the preceding claims, wherein each section of the passage is of a smaller cross-sectional area then the section upstream of 20 it.
8. An apparatus as claimed in any one of claims 3 to 6, wherein said bobbin has skew grooves in its largest diameter cylindrical surface whereby, in use, the material flowing in these grooves causes the bobbin to turn.
9. An apparatus as claimed in any one of the preceding claims, wherein the pressure chamber has an inlet which is located in a side wall of the pressure chamber
10. An apparatus as claimed in claim 9, wherein said outlet of the pressure chamber 30 is in an end wall of the pressure chamber, the inlet of the pressure chamber being between the outlet of the pressure chamber and the piston when the piston is at the end of its pressurizing stroke.
11. An apparatus as claimed in claim 10 and including an inlet valve having an open 5 position in which the material is permitted to enter the pressure chamber through the inlet of the pressure chamber and a closed position in which flow of the material to the pressure chamber is prevented, and a control system which maintains said inlet valve closed until after the piston has commenced a retraction stroke. 10
12. An apparatus as claimed in any one of the preceding claims, wherein the means for reciprocating the piston comprises an hydraulic or pneumatic cylinder in which there is a drive piston, a piston rod attached to the drive piston the piston rod extending through an end wall of the pneumatic or hydraulic cylinder, across a gap and being attached to the piston in the cylindrical bore.
13. A method of processing material which comprises: providing a reciprocating piston in a cylindrical bore and a pressure chamber which forms a continuation of the cylindrical bore; reciprocating the piston in the cylindrical bore in alternating forward pressurizing strokes 20 and return strokes; feeding the material to the pressure chamber and cylindrical bore, while the piston is retracted; pressurizing the material in the cylindrical bore with the forward pressurizing strokes of the piston and forcing the material under pressure from the cylindrical bore, directly 25 through the pressure chamber into a passageway under a pressure of between 20 and 200 MPa so that it emerges from the passageway at a speed of between 500 and 6000 causing the material to flow from the passageway through a passage comprising a plurality of sections including at least a first section and a second section, each of said 30 sections having an inlet end and an outlet end and each of said sections being at an angle with respect to the section which precedes it, said method being performed on apparatus comprising a first part that defines surfaces and a second part that defines surfaces corresponding to the surfaces of the first part, said passage being formed between said corresponding surfaces of the first and second parts; 5 urging the second part towards the first part with a bias mechanism, so that the material changes direction as it flows from one of said sections to the next: and providing an impact wall at the outlet end of each section so that the material, as it emerges from each section, impacts on the impact wall at the end of that section, changes direction and flows into the next section of the passage.
14. A method as claimed in claim 13, wherein the pressure is between 30 and 160
15. A method as claimed in claim 14, wherein the pressure is between 35 and
