Oil-press with mild cracking of olive-crop and washing of olive-mass with waste olive-water.

The invention refers to an oil-press for the extraction of oil without striking hard the olive-crop and with normal and easy separation of the oil from the core and the olive-water.

The currently existing technology manufactures oil-presses which crack hard the olive-crop resulting in "soap-like" olive-oil, relatively bitter, and then through rotation and centrifugal power the olive-water separates from the core and the oil is obtained, therefore having low yield of oil and poor quality. The aforementioned technical difficulties led to an attempt of seeking a technical structure and a novel method for extracting the olive-oil.

Thus, a first object of the present invention is the manufacture of an oil- press which achieves cracking of the olive-crop with two gear-wheels entangling each other, into which the olive-crop drops in order to be cracked . Afterwards, the cracked olive-crop is carried on a cylinder having a central axle with blades rotating and stirring the olive-mass. In the outer part of the cylinder there is a pipe which directs the already extracted olive-water into the cylinder for washing the olive-mass. After the olive-mass is washed, the separated oil mounts up onto the surface of the olive-mass inside the cylinder, and, due to pressure coming from t he incoming olive-water, it passes through t he pipe into t he container, wherefrom i t is received.

Th invention will be understood by those skilled in the art by reference to the accompanying drawings, wherein certain preferred embodiments of the invention are illustrated by way of example, wherein: Fig. 1 is a perspective view of the invented oil-press.

Referring to a selected typical example of an embodiment of the invention, a numbering of the main parts of the article takes place below, with reference to the corresponding numbering of these parts in the attached

drawings, wherein these are shown in typical descriptive illustration, without scale, simply in dimensional ratio between the parts.

According to the preferred typical embodiment of the invention, the invented oil-press consists of the following main parts, as these are marked on the attached drawing having same numbering:

1. A funnel for receiving the olive-crop provided onto the cracking member.

2. A pulley which moves the two gear-wheels of the cracking member and receives movement from the motor 3. Both toothed wheels have deep and wide gears, between which the olive-crop passes through and gets mildly squeezed. 3. An electric motor which rotates the two toothed wheels 2.

4. A funnel for receiving the olive-mass from the cracking member 2, with a flow switch, which directs the olive-mass into cylinder 5.

5. A cylinder-washing machine having a central axle wit h blades which rotate and stir up the olive-crop toget her wit h t he incom ing olive-water. 6. A cylinder blades rotating pulley 5, which rotates by the electric motor 1 8.

7. A vessel with heater for receiving the waste olive-water.

8. A pipe which guides the olive-water from the container 13 into the vessel- heater 7.

9. A pipe which guides the warm olive-water from the container 7 into the washing-machine 5 through the distributor, aided by the pump 19.

10. Olive-water distributor in the washing-machine 5, with small distributing pipes along the whole length of the washing-machine since the olive-mass, being at the bottom o the washing-machine, should receive olive-water aiong the whole length thereof. 1 1 . A shutter separating the olive-core from olive-water and oil.

1 2. A pipe carrying olive-oil and olive-water from the shutter 1 1 into container 13.

13. Container. A container with an inside chamber 20 for oil. The containei receives the olive-water and oil and separates in chambei 20 the oil, the olive- watei being discharged from the pipe 8 and guided into the heatei 7.

14. A pipe for drawing oil out of the vessel 20. 15. A port for drawing olive-core out of the washing-machine 5.

16 A vessel l eceiving core from the washing-machine 5

17 A pipe for di ming olive-watei J i om the washing-machine 5.

18. An electi IC motor for rotating a blade-cylinder pulley 5.

1 A pump electric motor for sending olive-water fiom heatei 7 to washing- machine 5.

20. Conical chamber inside container 13 receiving the separated with normal flow, due to mounting up on the surface,olιve-oiI.

The pi ocess of producing olive-oil with the invented oil-press is the following: The olive-crop drops into funnel 1 wherein the two toothed wheels rotating by pulley 2 are provided. The cracking of olive-crop takes place mildly and present no "soap-like" olive-oil, something that occurs when the o ve- ci p ci ack hai d. The cracked olive-ci op. constituting now the olive-paste oi olive-mass, di ops into funnel 4 whei efi om it is guided into washing-machine 5 Inside washing-machine 5, the olive-mass stπs up together with olive-watei guided into the washing-machine from the heater 7 at approximately 40°C temperature.

Olive-water from pre-treated olive-crop is guided into heater from container 13 through pipe 8, and is channeled into the washing-machine 5 by distributor 10 along the whole length of the washing-machine 5 through small pipes 10 Hot olive-water contains ingredients having the ability to wash thoroughly the olive-crop.

After stirring up and washing of the olive-mass inside the washing- machine 5, the olive-water together with the oil rises onto the upper surface of the washing-machine, wherein shutter 1 1 is provided. There, the said oil and olive-water pass through shutter and, pressurised by olive-water coming from pipe 10, rise into container 1 3 through pipe 12. Therein, the oil, being lighter, mounts up onto the surface and through slot 20 enters the conical vessel and, through pipe 14, exits into the collection vessel.

After complete extraction of the oil from the amount of olive-mass existing in the washing-machine 5, its rotation stops and this is channeled by air-drill inside the washing-machine 5 for drying the olive-crop and draining the liquids. Then, the dried olive-crop is removed through port 1 5, is dropped into vessel 16 and conveyed.

It must be considered that the object of the invention is not limited by the above example. The accomplishment of the invention is possible by other constructing ways, methods, accessories and mechanisms which still are within the scope of the present description.
