Definitions
- the invention deals with a modulating machine, used to extract and recover essential oil from citrus fruit such as lemons, oranges, mandarins, grapefruit, etc, wherein the peel is not removed, but by means of microperforation of the peel and disruption of the oil cells.
- the oil thus extracted is trapped in water, so as to form an aqueous emulsion.
- the Brazilian patent PI 8002964 describes a device to extract oil from the peel of non-round citrus fruit and refers to the non-suitability of the machines as described in the patents US 3,707,176, US 3,954,032 and US 4,070,959 for such an application.
- That device comprises a pair of parallel horizontal serrated cylinders forming recesses within them to receive the fruit, means to rotate said cylinders in the same sense and means to cause axial displacement movement relative to said cylinders, so that such axial displacement promotes a change in fruit direction relative to such cylinders. Furthermore, said cylinders are immersed in water.
- Oil extraction in that equipment is accomplished by cutting the fruit peel by the cylinders in a region below the water level.
- the Brazilian patent PI 8402231 refers directly to patent US 4,070,959 and presents an improvement therein introduced.
- the improvement consists of providing water spraying pipes, spaced apart inside the closed recipient, intended to spray water directly over the external surface of each fruit, thus carrying the essential oil extracted from them through the cylinder teeth.
- that improvement intends to keep any bacteria coming from so- called “lower quality” fruit from being transferred to good quality fruit through the "water bath”.
- the serrated rings have a slight inclination relative to the cylinder that supports them.
- - emulsion tank - there is one single tank with the purpose of a tank per se, with structure to receive the bearing of a disk shaft acting both as a bearing and sealing.
- Sealing uses an o-ring, which limits the shaft rotation to a lower rotation than the bearing. This does not allow increasing the rotation and processing ability of the machine;
- - bearing of disk shaft - the bearing is made of graphite chuck, it is self-aligning and has rolling purposes. It has axial translation and sealing to limit rotation, thus forbidding an increase in speed and in fruit processing capacity.
- Graphite used in the bearing promotes emulsion contamination, as it is in direct contact with said bearing;
- - axial movement system - operation is done by means of a rotating lateral axis, by intermediate vertical axis actuated by cylindrical cams, operated by means of arms and two axis simultaneously. That configuration requires a larger quantity of items, such as bearings for the lateral axis, vertical axis, fastening supports and further lubricating points;
- Another object of this invention is to provide a machine that extracts and recovers essential oil from citrus fruit, offering a significant improvement in recovering efficiency of the oil extracted from fruit.
- the machine of the invention is built into modules, thus allowing for quick changes in configuration for a required fruit processing capacity. Modularity occurs in both dimensions, length and width, thus allowing for flexibility as a function of different customer processing capacities. This characteristic provides easier manufacture and wider range of offer with a high proportion of common components and consequently a reduced number of special parts. It results in more flexibility to compose the final equipment, reduces stocks and increases the negotiation power when purchasing components, due to the larger availability of common components in the market. Furthermore, it makes the assembling process more easily managed, enabling the simultaneous realization of various sets for later final assembly;
- the tank project is separate from the equipment structure, thus facilitating its manufacture, installation and maintenance. That solution allows for more flexibility as to concepts for disk axis sealing, thus favoring -the elimination of emulsion leaks and loss through lateral collectors, by keeping the feeding and discharge in closed circuit. It also provides for modular assembly of sets of four disk axes, to make maintenance easier;
- independent disk axis sealing was projected to have higher limiting rotation values than in existing machines. It also allows for quick substitution, with no need to disassembling the disk axis bearing;
- the tank structure includes two lateral collectors, which main purpose is to collect emulsion leakage from the axis interface provided with rotation and translation movement with its sealing;
- - emulsion control control of feeding water flow in the tank by mean of valves and a fluxometer to control the oil content in the emulsion, in the process of citrus oil recovery;
- - automatic tank cleaning a nozzle system located in the bottom of the tank, with specific arrangement for cleaning during operation intervals;
- - spillway allows the control of water level in the tank, thus resulting in better exposure of the oil cell perforating disks according to the size of the fruit to be processed. Its configuration allows for self-cleaning of floating solid matter;
- - axial movement system effected by two lateral axes with oscillatory movement, by using the concept of handle rod and through an arm directly activating disk axes simultaneously and within alternate positions;
- - disk cleaning system set located above disk axes, equipped with lengthwise translation operation following the natural fruit flow, simultaneously arranged to the fruit removing system;
- - automatic lubrication system consisting of an electrical panel with pumping, distribution and monitoring lubrication center for the bearings and chains.
- a timer operation eliminates manual intervention and reduces lubricant consumption by monitoring lubricant levels, thus resulting in longer working life for components, lower operational costs and avoiding stops for maintenance;
- - fruit washer and drier with separate operation consisting of a first set of grooved rolls to facilitate washing water flow and a second set of subsequent rolls to dry the fruit.
- FIG. 3 shows an upper view of the emulsion tank
- FIG. 4 shows a longitudinal view of the lateral collector
- FIG. 5 shows a lateral section view of the emulsion tank, stressing axis sealing
- FIG. 10 shows an enlarged front view of the axial movement set
- - Figure 11 shows a front view of the disk cleaning set
- - Figure 12 shows a side view of the disk cleaning set, stressing the spraying nozzle.
- FIG. 13a, 13b and 13c show respectively side, front and higher views of the fruit washer and drier
- the modulating machine for extraction and recovery of oil object of this invention consists of a basic or chassis structure (1), in which lower portion there is an installed transmission set formed by pulleys (2) and serrated chains or belts (3) operated by a motor (4). That set transmits by means of axis (5) movement to a range of pulleys and chains (which are illustrated and described below) , which re-transmit such movement to other pulleys providing for movement to the supporting axes (8).
- Over said supporting axes (8) there are serrated disks (9) responsible for the extraction of citrus oil from fruit.
- said supporting axes (8) are provided with alternated axial movement, by means of an operation set (10) interconnected to a motor reducing set. Said sets are connected to the piston rods (11) which transmit alternated movement to the handles
- FIG. 3 shows an upper view of the emulsion tank (15), which consists of two contiguous cells (15a) and (15b) provided with inclination towards their corresponding longitudinal axes (15c) and (15d), alongside which sets of spraying nozzles (17) are appropriately positioned.
- Said tank is surrounded by side walls to form a kind of tub to retain the collected water-citrus oil mix inside it and keep the discharge feeding outlets (15g) and (15h) .
- lateral collectors for emulsion leakage (16) and (16') can be seen, and the spillway (30) on the rear side.
- Figure 5 shows the emulsion tank (15), stressing the supporting axis (8). It can be seen that said emulsion tank (15) is supported on its center over a structure (19) and has a bottom with inclination " ⁇ " towards its longitudinal axis and cleaning discharge (15g) .
- the sealing set (20) of said supporting axes (8) is separate for each axis and allows for quick substitution with no need to disassemble the bearing.
- Figure 7 shows the spillway (30) equipped with "V"-shaped cut-outs (31) through which the water-citrus oil emulsion will drop towards the collecting and transfer box.
- Dimensions and quantity of cut-outs on the spillway will depend on specific characteristics of the machine project, such as capacity and flow.
- FIG 8 shows a section view of a bearing (40) of the supporting axes (8) of disks (9), representing rotation-bearing means.
- Said bearing (40) is of the linear- rotatory kind and comprises a chuck (41), eventually made of bronze, equipped with graphite blades (42), internally mounted over a self-aligning roll (43) located inside the base (44).
- FIG 9 shows the set for rotational movement of the supporting axes (8), including a series of modules (50) comprising a pair of pulleys (51) and (52) assembled over the corresponding supporting axes (8) and (8'), which are operated by means of a chain or belt (53). Said supporting axes (8) and (8') are axially operated by means of handles (54) and (55) mounted over a lateral axis (56).
- the quantity of modules (50) existing in the machine object of the invention will only depend on the dimensional characteristics of the project.
- Figure 10 shows in further detail the handle (12) rod (11) set for axial operation of the supporting axis (8) , where it can be seen that the connection with said elements is made by the end (13) of said supporting axis (8).
- the set is moved by a motor reductor (14) and an operation device consisting of a pulley (10) to which a pair of rods (11) is connected.
- Figures 11 and 12 show the disk cleaning set (9).
- Such set consists of a transversal structure (60) laterally supported by pulleys (61) and (62), with a fruit removal bar (63) articulated therewith in a suspended fashion.
- Said structure (60) supports a series of spraying nozzles (64) used to clean said disks (9) .
- the cleaning set is located above the disk (9) axes (8) and is provided with lengthwise movement, following the natural flow of fruit.
- This set has the purpose to remove the remaining fruit over the disks (9), when the fruit feed is interrupted, and simultaneously promotes the displacement of the spraying nozzle set (64), simultaneously cleaning the mentioned disks (9) by the action both of water jet pressure from the nozzles and the disk rotation.
- the cleaning water feed can be made by means of a flexible hose with high-pressure joint and provided with a degree of liberty for rotation.
- FIGs 13a, 13b and 13c show the fruit washing and cleaning unit.
- Such washer/drier is mounted over a supporting structure (70) and consists of a feeding slope (71) for fruit which just passed by the disks (9), which are thrown over a first set of grooved rolls (72), over which a structure (73) supporting a set of spraying nozzle set (74) is located.
- the purpose of this first set of grooved rolls (72) is to provide for washing of the fruit from which the essential oil has been extracted, removing the still remaining oil over its surface.
- a second set of flat rolls (76) which have the purpose to dry the fruit surface immediately upon washing by the first set of rolls. The fruit then dried are discharged over the slope (77).
- Both the first (72) and the second (76) sets of rolls are located inside a collecting tub (78) provided with emulsion discharge pipes (79). Also, both the first (72) and second (76) roll sets are provided with rotational movement as offered by a motor reductor set (100) and chains (81).
- Figure 14 shows the scheme of the automatic lubrication system of the machine.
- the lubrication system developed for the machine has the main purpose of providing for the application of oil and grease at specific points, with flow and time intervals duly regulated to guarantee the machine operation within ideal lubrication standards.
- the lubrication system includes therefore a lubricant command/pumping/tank frame (80). From that frame (80), specifically from the lubricant tanks, two pumps send oil and grease, respectively, to a central distributor (81). A timer circuit operates said oil and grease pumps, while the lubricant level in the tanks is sensed for replenishment.
- Throug appropriate sets of pipes (82), (83) and (84), oil and grease are sent to a number of controlled flow distributors (85), (86), (87) and (88) , from which they are sent to the application points, such as bearings, chains and others.
- Said distributors have holes with calibrated diameter for flow control in as many lubrication points.
- said controlled flow distributors (85), (86), (87) and (88) are strategically located around the emulsion tank (15).
- each controlled flow distributor for the sets (85), (86), (87) and (88) has a specific connection to the central distributor (81) through the corresponding pipes (82), (83) and (84) .
- special pipes (89) equipped with derivation blocks (89') and (89") feed a controlled flow distributor (90) installed to make the lubrication of elements from the fruit washing and drying unit (78) .
- This lubrication system therefore allows increasing the working life of the machine object of the invention, while reducing the frequency of maintenance and lubricant consumption.
