44162/2 »ant> ΐρηηι Taw o' taon o»»n»s oVa %-n>ina/ iD»» nn and apparatus Procees/for pretreating oil-oontaining vegetable raw materials Stork Amsterdam B.V.
This invention relates to processes for the pre-treatment of oil-containing particulate rav vegetable material.
A process is already known in the art according to which oil-containing seeds are heated in so-called cookers or flour boilers in the presence of moisture. A flour boiler comprises a vessel with a plurality of hollow plates disposed one over the other, each provided with a passage which discharges over a plate situated thereunder. The oil-containing seeds are essentially indirectly heated by the piaires.
In order to extract oil from oil-containing raw vegetable material such as fruits, or seeds, by crushing or by means of solvents, it is necessary to expose vegetable material to a number of pre-treatment steps prior to extraction of oil therefrom. Irrespective of specific pre-treatments for various kinds of seeds and differences due to a choice between extraction by crushing or by means of solvents, the following pre-treatment steps may be necessaryt removal of shells, skins or husks, pulverizing, rolling, heating, drying and cooling.
Depending upon the type of vegetable material and the process by which the oil is extracted, one or more of these pre-treatment steps are required and some of the pre-treatment steps may have to be performed simultaneously. Although the meohanism of the pre-treatment steps is not yet entirely known, it can be suggested that the pre-treatment steps have the following effect: - cell material is opened, whereby oil therein is more easily released) - 2 - 44162/3 The known process discussed above suffers, however, from the disadvantage that the residue of the vegetable material in the cooker or flour boiler often exceeds the optimum time necessary so that a uniform well-controllejLtreatment of the vegetable material is impossible. This is caused by poor heat conduction and heat transfer due to the fact that the heat supply to the vegetable material is substantially indirect, that is to say it is effected via a heat exchanging surface of the hollow plates. Moreover heat conduction through the vegetable material is insufficient, because it is treated in a mass.
According to one aspect of the present invention, there is provided a continuous process for the pre-treatment of oil-containing particulate raw vegetable material in order to improve the extraction of oil therefrom comprising the steps of loosening the particles of vegetable material from each other so that the particles are in a loosened state and applying a gaseous moisture and/or heat transferring fluid directly into the interior of the mass of vegetable material when the particles thereof are in the said loosened state.
One thus may achieve by this process an excellent heat and moisture transfer, with a resultant considerable reduction of the required treatment times and a more uniformly controlled treatment of the vegetable material.
Preferably the vegetable material is disposed in a relatively thin layer and is subjected to a vertical shaking treatment and oonveying treatment, during which the gaseous moisture and/or - 3 - 44162/3 in the loosened state.
Consequently a remarkable Improvement may be obtained due to the result of mutual collisions and due to the fact that they are separated from each other for a short time, in which time the gaseous moisture and/or heat transfering fluid can easily act upon each individual particle.
During the removal of excess moisture, it is also advisable to have the particles of vegetable material close to each other for a short time and to keep tehm further apart for a short time.
The action of moisture and heat on the vegetable material is effected by bringing the vegetable material into direct contact with the gaseous moisture and/or heat transfering fluid.
So as to obtain . desired conditions of the vegetable material, one may use air with a temperature between 15°C to 150°C, steam, cold water as the gaseous moisture and/or heat transferring fluid. Due to the fact that the gaseous moisture and/or heat transferring fluid directly contacts the vegetable material local superheating or even lump formation owing to local moisture accumulations, are substantially avoided. When the vegetable material is in a relatively thin layer the layer may be between 1 and 10 cm. in thickness.
According to a further aspect of the present invention there is provided a device for carrying out the process recited above comprising a treatment space having a perforated wall bottom in which oil-containing particulate raw vegetable material is subjected to a pre-treatment ; loosening means for loosening the - into the interior of the mass of loosened vegetable material when the particles thereof are in the loosened state.
The invention is illustrated merely by way of example in the accompanying drawing which illustrates schematically a device for carrying out a process according to the present invention.
A particulate raw vegetable material 3 to be treated, e.g. beans, seeds, or fruits, whether previously broken, shelled and rolled or not, is fed to a feeding and metering system 1 of the device shown in the drawing. The output material from the system 1 has then by virtu^e of preceding treatments (not shown), if any- a particular temperature value and mdsture content. In a first part 2 of a continuously operating device the material 3 is simultaneously moistened and heated by means of steam introduced through a pipe 4· For that purpose the part 2 is divided into a plurality of sections 5 to which both steam and heated air can be supplied through bottom walls 6. The transport of material in the device is performed by a combination of the overflow principle and a vibration as of a shaking gutter 9a whilst heat and moisture transfer is directly applied whilst the material is in fluidlzed condition. As a result one can considerably reduce the time during which the material 3 stays in the part 2, in order to attain the necessary predetermined process conditions for the second stage of the pre-treatment. Usually the vegetable material does not stay longer than 5 minutes in the part 2, contrary to the time required in the conventional cookers which is in the range of 5 to 20 minutes. In the second stage of the treatment ensuring a uniform temperature at this stage of the process one avoids the possibility of subjecting the vegetable material to an excessively high temperature. After the second stage of the pre-treatment of the vegetable material the latter is introduced into a third part 8. In the part 8 the moisture content and the temperature of the vegetable material is reduced to values required for the extraction of oil therefrom by cruehing or by means of solvents. In this part 8 a combination of the overflow principle and vibrations is used, whereby the particles of vegetable materia} ο,τβ temporarily held apart, while the transfer of heat and moisture is effected in a more or less loosened state by means of air.
The above described process leads tot a. very short and unifd&om residence times between 2 and 10 minute in the parts 6,7, 8 contrary to the conventional residence times of between 20 and 45 minutes, while in order to attain the desired conditions of the Vegetable material, air with a temperature between 15°G and 150°6, steam or cold water can be used: b. a direct contact between the moisture and heat transferring fluid and the vegetable material whereby local superheating or lump formation by local moisture accumulations is avoided.
Preferably the device comprises one or more shaking for the vibrating movement. Shaking gutters with a perforated bottom wall covered by strips as described in the U.S. Patent tively large quantity of moisture, without any risk of crusting or obturation of perforated bottoms, through which steam, hot or cold, dry or wet, air can be passed.
It should be noted that due to the vibratory motion of the shaking gutters a certain loosening effect is produced which is enhanced by the gaseous moisture and/or heat transfer* ring fluid supplied through the bottom wall of the shaking gutter.
