Description

Method for the regulation of the absorption of oxygen or any other gas .
The present invention relates to a method for regulating the absorption of gaseous oxygen, or other gases, by fluids or pastes obtained by means of grinding or crushing of raw materials, in particular vegetable matter, according to the preamble of the main claim. The invention also relates to a plant for implementing the abovementioned method, according to the preamble of the corresponding main claim.
By way of a non-limiting illustration, in the present invention reference will be made to the pressing of olives as an example of vegetable matter and to oxygen as the element whose content within the fluid obtained is to be regulated.
As is known, pressing consists in breaking up the olives using mechanical means, mainly by means of crushing or impact, and has the aim of forming a paste, commonly known as "olive paste", which will undergo a subsequent kneading process, this process being intended to break up the emulsions which form during pressing and facilitate the subsequent separation of the oil from the remaining components of the paste. The olive paste, owing to the way in which it is obtained, contains dissolved oxygen and, incorporated therein, small gas bubbles with a composition similar to the atmosphere present in the press during pressing.
As is known, oxygen, like other substances in the gaseous state, dissolves in a fluid, i.e. in the olive paste in the case in question, in amounts regulated by physical laws, depending on its partial pressure, on the temperature of the fluid and on other characteristics related to the type of fluid and the system as a whole, such as stirring, the contact time, etc. The oxygen, moreover, in the case described here is also contained in the atmosphere present in the press and consequently in the small bubbles incorporated in the paste-like fluid. These small bubbles release oxygen to the paste also after pressing, in particular during kneading.
It is to be considered that usually the presses operate at atmospheric pressure and therefore the partial pressure of the oxygen in the atmosphere contained by them coincides with its mole fraction.
The kneading process usually has a duration varying from twenty to fifty minutes and may be loosely described as a slow remixing of the paste inside a special container called a kneader. It is known to persons skilled in the art that, during the kneading operations, the oxygen dissolved in the paste, if present in concentrations such as those present following turbulent contact of the latter with the air (as occurs during pressing) , produces oxidation effects which impair the quality of the oil and moreover result in the need for frequent cleaning and sanitization of the kneaders .
These are the reasons why it is important to reduce and control the oxygen in contact with and dissolved in the olive paste.
Known techniques aimed at keeping the oxygen at optimum concentrations within the gaseous phase inside the kneader exist, this phase being in contact with the paste during kneading. These techniques, although rapidly forming and maintaining for the kneading time an atmosphere with an optimum composition in contact with the separation surface of the paste, have the limitation consisting in the fact that the small gas bubbles incorporated in the paste, during pressing, rise very slowly to the surface of the paste where they break and form again, possibly, with an optimum composition, such as that existing in the protective atmosphere formed inside the kneader. The slowness of the breaking-up process and any formation of new small bubbles with an optimum composition is almost inevitable and is due to the necessary slowness of remixing inside the kneader.
With this technique the time required to reduce the oxygen contained in the paste to optimum values is decidedly greater than that needed for oxidation and deterioration of the components of the oil and therefore, by means of the known method, the deterioration of these components is only partly avoided.
The object of the present invention is to overcome the limitation indicated above by means of a method and an improved plant able to ensure that the oxygen dissolved in the paste-like fluid, such as olive paste, is kept within optimum amounts, so that there is no deterioration of the components of this paste-like fluid when processed.
In particular, the object of the invention is to provide a method and a plant of the type mentioned which, by obtaining a gaseous atmosphere with an optimum composition inside the press during processing of the paste-like fluid, ensures that the small bubbles incorporated in this fluid or paste have the same composition as the atmosphere and consequently the dissolved oxygen possesses predefined, desired, optimum values .
For the purposes of reducing the oxygen content one method is that of operating within the press at a pressure lower than atmospheric pressure, thus reducing the partial pressure thereof.
The present method is based on the fact that the partial pressure of the oxygen may be reduced by reducing its mole fraction in the atmosphere in contact with the olive paste during and after its formation.
The object of the present invention is therefore that of solving the problem of the excess oxygen in the olive paste, not by removing it during the kneading step, as occurs in the known techniques, but by regulating its incorporation during the stage preceding that of kneading, namely during pressing.
These and other objects which will become clear to the person skilled in the art are achieved by a method and a device according to the accompanying claims. - A -
For a better understanding of the present invention the following drawing is attached purely by way of a non-limiting example. In this drawing:
Figure 1 shows a schematic and generic view of a plant according to the invention;
Figure 2 shows a schematic view of a different embodiment of the invention;
Figure 3 shows a diagram in the case where the crusher or press is of the disk type. With reference to the Figures, Figure 1 shows schematically an olive press 1 - a device which is known per se - equipped with a hopper 2 for loading the olives, a conveyor 3 for unloading the paste-like fluid or olive paste, a line 4 for supplying a gas or gas mixture provided with a regulating/interceptor valve 5 and a probe 6 for taking samples of the gaseous mixture to be sent to an analysis system (not shown in the figures) .
10 denotes the flow of olives entering the press, 9 denotes the paste leaving it and 7 any gaseous mixture discharged from the press 1.
Figure 3 may be regarded as a particular case, shown on a larger scale, of Figure 1 where the press 1 consists of an external containing structure Ia, a stator 20, an element integral with the containing structure Ia, and a rotor 21 rotating about its axis 12.
The hopper 2 has a feeder screw 11 rotating about its axis and, in the case shown by way of example, coinciding with the axis 12.
The operating principle of the system, briefly and with reference to Figure 3, is as follows: the olives are introduced into the hopper 2 and pushed by the feeder screw 11 towards the centre of the rotor 21 which is suitably shaped and, during its rotation, crushes the olives and forms the paste.
The circular movement of the rotor 21 pushes the paste radially towards the containing structure Ia which conveys it towards the outlet 3. The presence of the paste on the conveyor 3 prevents the gaseous atmosphere inside the press from escaping from the conveyor.
The press 1, the loading hopper 2 and the discharge conveyor 3 must have at least one discrete gas seal, limiting as far as possible the exchanges of gaseous volumes with the surrounding environment. Poor sealing of these components with respect to the exchange of gaseous volumes results in wastage of gas or mixture to be supplied, and if this wastage is considered to be excessive, the components must be suitably sealed using means which are known per se and which are outside the scope of the present invention.
The formation of the gaseous atmosphere with an optimum composition inside the press 1 is obtained by supplying in suitable quantities: oxygen-free gases, such as N2, Ar, CO2 or mixtures thereof, or mixtures with the required oxygen content if the object is to have an atmosphere inside the press with the given oxygen composition alone,
- gaseous mixtures having a given composition if atmospheres inside the press having a given composition with respect to both the oxygen and other components are required. By way of an example, which is not limiting however, one of the possible ways of obtaining a mixture with the desired composition using the plant shown in Figure 1 is described.
Via the line 4, by opening and if necessary regulating the valve 5, a quantity of gas or mixture sufficient for obtaining inside the press itself an atmosphere with a desired composition is supplied inside the press 1, said composition being measured by the special analyzer which analyses the samples of gaseous mixture taken by the probe 6. The operation of supplying gas or mixture is performed immediately before and during pressing.
The gases or gas mixtures are contained inside tanks outside the press or, as in the case of N2, may be obtained by means of machines for separating the gas from the air.
The quantity of gas or mixture to be used depends both on the quantity of paste produced and on the type and characteristics of the press and the quantity of oxygen which is required.
By way of example, with reference to a tonne of paste, in order to obtain a mole fraction of oxygen, in the atmosphere in contact with the paste and in the small bubbles incorporated, equivalent to about 0.05 - 0.08 (such as that optimum for the quality of the oil produced), the consumption may range from 0.5-1 Nm3 for presses with mixers arranged inside special sealed boxes, to 3-5 Nm3 in disk or hammer presses provided with normal sealing means.
It is to be considered that the current systems for containing the oxygen inside kneaders have a consumption approximately the same as that of disk or hammer presses, but result in a protective effect which is decidedly lower.
The supply of gases or a mixture via one or more lines 4 provided with one or more valves 5 may be performed automatically, managing the opening, closing and regulation of the valves depending on the composition of the internal atmosphere sampled by one or more probes 6 and measured by an analyzer (not shown in the Figure) . This is performed with the aid of a PLC, a microprocessor unit or equivalent systems, which are nevertheless known per se. Figure 2 shows schematically and in generic form a plant able to perform, in addition to that described above, also the controlled-temperature refrigeration of the pressing operation. In fact, if it is desired to produce also the olive paste in a refrigerated environment and at a controlled temperature, this may be achieved by supplying suitable quantities of cryogenic fluids such as CO2, N2, Ar in the liquid or gaseous state at suitable temperatures, via lines 4a provided with interceptor/regulating valves 5a and where the internal temperature is detected by special thermometers 6a. Inside the press, the cryogenic fluids in the liquid state or the gases at suitable temperatures draw off heat from the paste-like vegetable matter or fluid which at the same time cools. The supplying of the necessary quantities of these fluids may be performed automatically, by managing the opening, closing and regulation of the valves depending on the values of the temperature measured inside the press by means of one or more thermometers 6a, with the aid of PLC units with microprocessor or equivalent systems known per se.
Preferred embodiments of the invention have been described. Other embodiments are also possible, however, in the light of the above description and are to be regarded as falling within the scope of the present invention.
