Description

l P 136366NL00 Title: Method and apparatus for separating egg liquid The invention relates to a method and apparatus for separating egg liquid. Egg liquid separation processes and respective systems are known in various variants. Generally, egg liquid separation concerns separating (whole) yolks and albumen, in particular after breaking ofrespective eggs. W02016053093 discloses an example ofan apparatus andmethod for collecting and separating egg uid, comprising, successively, breaking an egg whereby receding egg halves are obtained, and separately collecting egg yolk and albumen in a separate egg yolk cup and albumen cup provided one above the other, each as a part ofa collecting unit which is advanced in a conveying direction. At least a part ofthe albumen is guidedfrom the egg yolk cup andows out downward via at least one outow opening in a wall part ofthe said egg yolk cup and substantially asymmetrically in relation to the conveying direction. As is mentioned in the document, during collecting, briefback- and- forth movement, or shaking, ofthe breaker unit can be allowed to recover as much uid from the egg halves as possible. Besides, it is known to shake the egg yolk cup, with a predetermined fixed amount of shaking, to enhance yolk-albumen separation. Another example ofan egg liquid separation system andmethod is described in NL1010910, the method comprises breaking the eggs, separating the egg contents from the shells, and supplying the egg contents to a means for separating the white and yolk, following which a check is made (e.g. using video means) for yolk in the white and for broken yolks. If yolk is detected in the white, the yolk pieces are removed, e.g. by additional separation means such as blowingmeans of suction means. The system includes an obliquely extending separation trough having an elongated central slit, such that liquid egg white (albumen) can leak downwardly through the slit (to be received in an egg white discharge reservoir)while respective yolks can be guided along an upwardly facing surface ofthe separation trough (towards an egg yolk collector / reservoir). It has been found that egg liquid separation provided by known systems not always leads to good egg liquid separation results. As a result, under certain conditions undesired amounts ofalbumen can still be present in yolk that is produced. Besides, under certain conditions, system operation can lead to breaking of (released) yolks which leads to undesired mixing of yolk material into the released albumen. Also, egg processing speeds of known systems can be relatively low. Known systems usually require a relatively large amount ofhuman system operator handling / intervening during use (in particular for setting and ne-tuning system operating parameters to provide good egg liquid separation results), leading to increase ofoperational costs. The present invention aims to provide improved egg liquid separation, in particular overcoming or reducing disadvantages ofknown methods and system. More in particular, the invention aims to provide egg liquid separation that can efciently and reliably separate yolk and albumen. To that aim, the invention provides a method and apparatus as dened by the features ofthe independent claims. According to an aspect ofthe invention, advantageously, there is provided a method for separating egg liquid, in particular for separating yolk and albumen, including: -providing egg liquid, containing yolk and albumen, from a broken egg; and -separating the albumen from the yolk using one or more adjustable egg liquid separation parameters; wherein at least one ofthe one or more egg liquid separation parameters is automatically adjustedbased on predetermined information. In this way, improved, efcient and more reliable egg liquid separation can be achieved, compared to known processes. For example, the egg liquid can be providedby an egg liquid separation structure that is congured to separate yolk and albumen using one or more adjustable egg liquid separation parameters (the egg separation structure e.g. being congured to utilize saidpredetermined information to adjust respective one or more egg liquid separation parameters ). In particular, the invention provides a exible process that can automatically adjust egg separation (using predetermined information e.g. as control information for controlling an egg separation step), to provide optimum separation results. To that aim, various types ofpredetermined information can be used. As an example, the predetermined information can be or include specific (origin) information relating to the broken egg before breaking, for example one or more of: - egg age information (egg laying date information) concerning the egg; -egg farm information and / or poultry house information concerning the egg; and -avian specic information concerning the egg. More particularly, such information can be selected from the group consisting of: 1. a-priori data, including one or more of: 1a. an age ofthe egg in days, or a number of days since the laying ofthe egg (e.g. 5 days); 1b. Respective chicken age (e.g. 30 weeks); 1c. Respective chicken breed (e.g. Hendrix Genetics Babcock Brown); 1d. Egg color (e.g. brown; being an indicator ofchicken breed / variety); 1e. Feed type and / or contents ofspecic nutrients offood that has been fed to the respective chicken (e.g. calcium content, which could impact shell thickness); 1f. Egg production conditions and / or storage conditions concerning the egg, especially temperature andhumidity (which inuence the evaporation ofegg liquids); this can include information concerning different (subsequent) storage locations, starting e.g. from a chicken house up to a packstation; 1g Egg ock information, e.g. an eggock identication code; and 1h. Batch average egg weight ofa previous batch ofthe same ock. It has been found that an origin ofan egg can be ofsignicant inuence ofegg liquid separation results. The invention can make use of such egg specific origin information to automatically adjust one or more egg liquid separation parameters, for optimizing respective egg liquid separation results. In addition or alternatively, the predetermined information (e.g. egg separation control information) can be or include information concerning yolk and / or albumen ofone or more earlier broken eggs. For example, a result ofthe separating ofthe albumen from the yolk ofa (rst) number ofeggs can be automatically monitored, to (e.g. continuously) generate egg breaking evaluation information, wherein the resulting egg breaking evaluation information can be used as predetermined information for subsequent breaking ofa further (second) number of eggs. In particular, according to a further embodiment, the method can include processing a plurality of eggs, including breaking each egg for providing egg liquid containing yolk and albumen, the method further including: -separating the albumen from the yolk from at least one rst broken egg; -automatically evaluating a result ofthe separating ofthe albumen from the yolk ofthe at least one first broken egg and generating corresponding evaluation result information concerning the separating of the at least one first broken egg, the evaluation result information in particular providing saidpredetermined information; -automatically adjusting at least one ofthe one or more egg liquid separation parameters based on the generated evaluation result information concerning the separating ofthe at least one first broken egg; -separating the albumen from the yolk, from at least one second broken egg, using the one or more adjustable egg liquid separation parameters with at least one ofthese parameters being adjustedbased on the evaluation result information concerning the separating ofthe at least one rst broken egg. In this way, the egg liquid separation process can be automatically adjusted, in particular without requiringhuman intervention to adjust one or more egg separation parameters. For example, the automatically evaluating ofthe result ofthe separating ofthe albumen from the yolk ofthe at least one rst broken egg can include measuring at least one physical characteristic ofthe yolk and / or albumen,. The at least one physical characteristic can e.g. be selected from: - a viscosity ofthe yolk and / or albumen; - a temperature ofthe ofthe yolk and / or albumen; -a dry matter content ofthe yolk and / or albumen; (e.g. a relatively large amount ofalbumen in the yolk, due to poor egg liquid separation, generally lowers a dry-matter percentage); -an optical density ofthe albumen (presence ofyolk in the albumen will negatively affect albumen optical transparency); -apH value ofthe yolk and / or albumen (pH ofegg liquid is an indicator ofegg age and therefore yolk firmness); and -aow characteristic ofthe yolk and / or albumen (e.g. detected by a mass ow sensor). In each case, for example, a said physical characteristic ofthe yolk and / or the albumen can be automatically compared (e.g. by a system controller) to a (predetermined) threshold value or desired value ofthe respective physical characteristic, wherein evaluation result information can include or be based on a deviation (if any) between a determined physical characteristic and a respective threshold value or desired value. Preferably, according to an embodiment, said automatically evaluating ofthe result ofthe separating ofthe albumen from the yolk of the at least one first broken egg can include determining a broken yolk ratio. Optionally, a determinedbroken yolk ratio can be automatically compared (e.g. by a system controller) to a (predetermined) threshold value or desired value ofthat ratio, wherein evaluation result information can include or be based on a deviation (ifany) between a determined ratio and respective threshold ratio or desired ratio. Further advantageous embodiments can include one or more ofthe following features that provide good results: - the separating ofthe albumen from the yolk includes agitating an egg liquid separation structure, containing the egg liquid to be separated, using one or more shaking parameters, for example a shaking frequency and / or shaking velocity, wherein at least one shaking parameter is automatically adjusted based on the predetermined information; -the separating ofthe albumen from the yolk includes blowing pressurized air towards the egg liquid using one or more air blowing parameters, in particular in a downwards direction, wherein at least one air blowing parameter (e.g. ow rate) is automatically adjusted based on the predetermined information; -the separating ofthe albumen from the yolk includes sliding the liquid along a chute structure, wherein at least one chute structure parameter ofthe chute structure (e.g. a slit width and / or chute slope) is automatically adjusted based on the predetermined information; and - the egg liquid is transported at a certain velocity along a transport path during the separating ofthe yolk and albumen, wherein the velocity is automatically adjustedbased on the predetermined information. Further, an aspect ofthe invention provides an apparatus for separating egg liquid, for example an apparatus congured to carry out a method according to the invention. According to a preferred embodiment, the apparatus includes at least one egg liquid separation structure, congured to receive egg liquid of a broken egg, the egg liquid separation structure being further configured to separate albumen and yolk ofreceived egg liquid using one or more adjustable egg liquid separation parameters, wherein the apparatus includes a controller for controlling the egg liquid separation structure, the controller being configured to receive predetermined information (e.g. egg separation control information) and to automatically adjust at least one of the one or more egg liquid separation parameters based on the received predetermined information. In this way, above-mentioned advantages can be achieved. The apparatus can be congured in various ways. For example, the or each egg liquid separation structure can include a cup, or alternatively a chute, configured to retain egg liquid yolk and to dispense egg liquid albumen of a broken egg. According to an embodiment, the or each egg liquid separation structure can include a slit having an adjustable slit width for passage of albumen. The controller can be congured to automatically adjust said slit width based on said predetermined information. In addition or alternatively, the apparatus can include at least one agitation device for agitating, for example shaking, at least part ofthe or each egg liquid separation structure, wherein the controller is configured to automatically adjust at least one agitation parameter of said agitating device based on saidpredetermined information. In addition or alternatively, the apparatus can include at least one blowing device configured for blowing pressurized air towards at least part ofthe or each egg liquid separation structure, wherein the controller is congured to automatically adjust at least one air blowing parameter ofthe blowing device based on said predetermined information. Preferably, the at least one egg liquid separation structure includes or is part ofa conveyor for transporting the egg liquid at a certain conveyor velocity. According to a further embodiment, the controller can be congured to automatically adjust said conveyor velocity based on said predetermined information. According to a preferred embodiment, the apparatus includes or is associated with at least one egg breaker congured for breaking eggs and for supplying respective egg liquid to said at least one egg liquid separation structure. For example, the apparatus can be part ofan egg breaking system, as will be appreciatedby the skilled person. According to a further embodiment, the apparatus can include an egg liquid evaluation device configured to evaluate a result ofthe separating ofthe albumen from the yolk and to generate corresponding evaluation result information, wherein the controller is configured to receive and process said evaluation result information for subsequent adjusting ofone or more egg liquid separation parameters. According to an embodiment, the controller includes or is associated with an information receiver configured for receiving the predetermined information. Further, as follows from the above, the predetermined information can be or include e.g. specic information relating to the broken egg (e.g. egg origin information) before breaking, for example one or more of: - egg age information (egg laying date information) concerning the egg; -egg farm information and / or poultry house information concerning the egg; and -avian specic information concerning the egg. In addition or alternatively, the predetermined information can include one or more of: -at least one physical characteristic ofyolk and / or albumen ofone or more broken eggs; and - a broken yolk ratio. Also, as follows from the above, the predetermined information can include aforementioned evaluation result information (concerning the separating ofthe at least one broken egg). In the following, the invention will be explained in more detail, with reference to the drawings that depict non-limiting examples. Therein shows: Figure 1 schematically an apparatus for separating egg liquid according to an embodiment ofthe invention; Figure 2 a perspective view ofpart ofa further embodiment ofthe apparatus shown in Figure 1; Figure 3 a side view ofpart the example shown in Fig. 2; Figure 4 part the example ofFigures 2 and 3; Figure 5 a perspective view ofan egg liquid separation cup ofthe example ofFigures 2-4; Figure 6 a perspective view ofpart ofa further embodiment ofthe apparatus shown in Figures 2-5; Figure 7 a perspective view ofpart ofan alternative embodiment of the apparatus shown in Figure 1; Figures 8A, 8B schematically top views ofthe example ofFigure 7, indicating two egg liquid separation states ofthe egg liquid separation structure; and Figures 9A, 9B schematically side views ofpart offurther alternative embodiments ofthe apparatus shown in Figure 1, indicating two egg liquid separation states ofthe egg liquid separation structure. Corresponding or similar features are denoted by corresponding or similar reference signs in this application. Figure 1 schematically depicts an apparatus for separating egg liquid (i.e. for separating yolksYfrom albumen B). The apparatus includes at least one egg liquid separation structure 1 (which can also be called an egg liquid separation system, an egg liquid separation assembly, and / or egg liquid separation means), congured to receive egg liquid B,Y ofa broken egg E. The egg liquid separation structure 1 is congured to separate albumen B and (whole, unbroken) yolkY ofreceived egg liquid using one or more adjustable egg liquid separation parameters (as will be explained in more detail below). Generally, the egg liquid separation structure 1 is arrangedimmediately after an egg breaking system or device 12, for directly receiving egg liquid B,Y therefrom. The egg breaker device 12 is preferably congured to break supplied eggsE without breaking respective egg yolksY (so that whole yolksY can be delivered to the subsequent liquid separation structure 1). Further, the apparatus includes a (central) controller C for controlling the egg liquid separation structure 1. Also, for example, the apparatus can include or be associated with one or more egg suppliers, e.g. one or more egg supply conveyors 33, for feeding eggs E (to be broken) towards or into the apparatus. An egg breaker device 12 (known per se) can be provided (arranged downstream ofthe one or more egg suppliers 33), for breaking the received eggs E (e.g. for decapitating or otherwise opening each ofthe eggs E that is fed into the apparatus during operation). The egg breaker device 12 can be congured to discharge (e.g. drop) egg liquid (containing albumenB and yolk Y) to or into a respective egg liquid separation structure 1. Also, the egg breaker device 12 can be congured to separate egg shells S ofbroken eggs E, and to discharge separated egg shell parts S towards an egg shell discharge port, e.g. to be collected in an egg shell collectorW (see Fig. 1). The egg liquid separation structure 1 can e.g. be congured to transport the egg liquid along an egg liquid separation path, e.g. via a respective (endless) conveyor 15 (see Figures 1-6), or via a chute 101, 125a, 201 (see Figures 7, 8, 9) and to allow separation ofalbumen B from (unbroken) yolkY during respective transport ofthe egg liquid, as will be appreciated by the skilled person. In particular, the egg liquid separation structure 1 can e.g. be congured to retain (and support) egg yolksY during such transport along the liquid separation path, to discharge those yolks to a yolk discharge port 36, e.g. to be collected in a yolk collector YC. The egg liquid separation structure 1 can e.g. include at least one yolk support, e.g. a plurality ofcups 25 (see Figures 3-5), or a chute 101, 201 (Fig. 7, 8), for retaining (and carrying or guiding) the egg yolksY along the separation path. In addition, the egg liquid separation structure 1 can e.g. be congured to downwardly dispense liquid albumen B (by gravity) towards an albumen receiver 14 during such transport along the liquid separation path, to discharge albumenB to an albumen discharge port 35, e.g. to be collected in an albumen collector AC. For example, a said yolk support can include or be associated with an opening (e.g. a gap 25a of a cup structure 25, see Fig. 5) or slit (e.g. slit 125b ofa chute 101, see in Fig. 7) for passage ofalbumen, e.g. towards an albumen collection structure 6, 26 that can be locatedbelow the yolk support 25, 125a. According to a preferred embodiment, the egg liquid separation structure 1, 101 includes at least one agitation device 2, 102 for agitating, for example shaking or vibrating, at least part ofthe or each egg liquid separation structure 1, 101. The agitation device 2 can e.g. be configured to cooperate directly or indirectly (e.g. via a respective conveyor) with a yolk support (e.g. a yolk cup 25, or chute section 125a), for shaking the yolk support during egg liquid transport along at least part ofthe egg liquid separation path. As an example, the embodiments ofFigures 1, 6 include an agitation device 2 having a toothed structure 2a, arranged for mechanically contacting (and e.g. guiding) passing opposite sections 15a ofthe egg liquid conveyor 15 during operation, causing respective yolk receiving cups 25 (being part ofthe conveyor 15) to shake or vibrate (e.g. in vertical directions), thereby enhancing discharge ofalbumen B out ofthe cups. It is preferred that the agitation device 2 includes an adjustment mechanism 2b for setting an amount of agitation (i.e. for adjusting a respective agitation parameter, e.g. an amplitude ofcup vibration and / or a frequency ofcup vibration), for example an adjustment mechanism 2b for adjusting a height position ofthe toothed structure 2a with respect to the passing cups 25 (to adjust vibration amplitude). According to an embodiment, the adjustment mechanism 2b can be configured to move the toothed structure 2a to an idle position wherein the toothed structure 2a does not cooperate with the conveyor 15 and does not effect yolk cup vibrations. According to an embodiment, the adjustment mechanism 2b can be configured to move the toothed structure 2a to a first position wherein the toothed structure 2a can cooperate with the conveyor 15 to effect relatively small (rst) yolk cup vibrations, and to move the toothed structure 2a to a second position wherein the toothed structure 2a can cooperate with the conveyor 15 to effect relatively large (second) yolk cup vibrations, said small (rst) yolk cup vibrations being smaller than said large (second) yolk cup vibrations (at the same conveyor speed). Similarly, according to an embodiment, a chute type separation structure 101 can include an agitation device 102, e.g. a shaking device, for vibrating or shaking at least part ofthe respective chute 101 (as is schematically depicted in Fig 7). Also in this case, the agitation device 102 is preferably adjustable, to change agitation ofthe respective chute section 125a, e.g. to change a frequency and / or amplitude ofvibration ofsuch a chute section 125a. In this case, the agitation device 102 can e.g. be a motorized agitator, an electromagnetic agitation device, a driven actuator and / or the-like, which can be directly or indirectly connected to a chute section 125a to effect agitation (shaking, vibration) thereof. In addition or alternatively, a preferred embodiment ofthe or each egg liquid separation structure 1 includes at least one blowing device 3 (known per se) configured for blowing pressurized air towards part ofthe apparatus, e.g. towards a said yolk support (e.g. a passing cup 25, or chute 101). Figure 1 depicts a number ofblowing devices 3, arranged above an egg liquid conveyor 15 for blowing air towards passing egg liquid during operation, to assist respective egg liquid separation. Similarly, the example ofFig. 6 shows a blowing device 3 having an array of air discharge nozzles 3a, arranged above the cup conveyor 16, for blowing air towards passing yolk support cups 25 during operation (and thereby enhancing discharging ofalbumen from those cups 25). The blowing device 3, 3 can e.g. include or be connected to an air supply duct 3b for supply ofpressurized air to respective air discharge nozzles 3a, wherein the air supply duct 3b can be connected to a pressurized air source (not shown), e.g. an air compressor or the-like. Figures 2-4 show a non-limiting example ofthe apparatus for separating egg liquid in more detail. The apparatus can be part of a system 10 for shelling eggs E (known per se). The egg shelling system can include e.g. a casing 1 1 defining a shelling compartmentA and an unloading compartment U.A shelling device 12 (i.e. an egg breaker) can be housed in the shelling compartmentA and can be configured to open egg shells of received eggs E. An unloading device 13 can be housed in the unloading compartmentU and can e.g. comprise at least one hopper member 14a, 14b, 14c suitable for receiving and unloading a shelling product (in particular albumen B, yolk Y, and e.g. a mixture ofalbumen and yolk respectively). Further, according to an example, the system can include a transport device 15 comprising e.g. one or more conveyors 16, 17 congured to separately transport albumen B and yolkYfrom the shelling device 12 to the unloading device 13. It is preferred that a conveyor speed ofthe transport device 15 is controllable by a respective controller C ofthe apparatus, for example for changing (increasing or decreasing) apparatus egg liquid processing speed. According to an example, the shelling device 12 can comprise at least one openingmember 34, ofa traditional type and configured to open an egg shell and cause the yolk and albumen to fall. The conveyors 16, 17 of the examplemay e.g. comprise at least a rst conveyor 16 having a plurality of seats each adapted to house yolk, and at least a second conveyor 17 having a plurality of seats each suitable for housing albumen. As will be appreciated by the skilled person, each openingmember 34 can be placed above the rst conveyor 16 to discharge a yolk for each seat ofthe latter. The first conveyor 16 can be placed above the second conveyor 17 to discharge albumen into the seats ofthe second conveyor 17. For example, the conveyors 16, 17 ofthe system may comprise a plurality ofmodules 22, each comprising at least one ofthe seats, and which can be connected in sequence to form respectively a first chain member and a second chain member, which are closed in a ring. Also, a first transmission unit 23 and a second transmission unit 24 can be provided to which the chain members can be connected andbetween which the latter extend, dening a forward sectionD and a return sectionR ofthe chain members which extendfrom the shelling compartmentA to the unloading compartment U. For example, Figure 4 illustrates a shelling device 12 and an unloading device 13, which in Figure 3 are schematizedby a dashed line. The unloading device 13 ofFigure 5 has some parts removed to facilitate their intelligibility. In Figure 4, in particular, the conveyors 16 and 17 are seen, where the first conveyor 16 is seen in the forward sectionD where it hides the second conveyor 17 which is under it. On the contrary, in the return sectionR the second conveyor 17 is visible and hides the first conveyor 16 which is under it. In the example ofFigure 4 it can be seenhow the conveyors 16 and can be integrated in a single product which has a plurality ofmodules 22, which form lines and rows respectively transversal and longitudinal with respect to the direction ofadvancement M. The first chain member and the second chain member can constitute a single product, that is, consist of a single chain member. The seats ofthe conveyors 16, 17 can be dened respectively by a first spoon element 25 and a second spoon element 26, for example like those illustrated in Figure 5. Each module 22 can comprise a rst spoon element 25 and a second spoon element 26 which can be reciprocally positioned in such away that, along the forward section D, the rst spoon element 25 is positioned above the second spoon element 26, when the apparatus 10 is in use. The rst spoon element 25 can be congured in such a way as to retain a yolk and discharge the albumen ofan egg. For example, it can have at least one opening or holes 25a positioned and configured not to allow the passage of a whole yolk but to allow the passage ofthe albumen that surrounds it. The second spoon element 26 can be congured so as to receive an albumen unloadedfrom the first spoon element 25 ofthe same module 22. Optionally, an unloading device 13 ofthe system can comprise an emptyingmember (known per se) operable to interfere with the respective second conveyor 17 in a first unloading position F ofthe unloading compartment U.A rst hopper member 14a ofthe at least one hopper member 14a, 14b, 14c can be positioned so that, in use, it is under the second conveyor 17 in the first unloading position F to receive the contents ofthe seats ofthe second conveyor 17 . The emptyingmember can be congured to cause, following its actuation, a fall ofthe contents ofthe seats ofthe first conveyor 16 when these pass through the first unloading position F during the operation ofthe apparatus 10. For example, the emptying member can be congured to rotate the second spoon 26 in such a way as to cause it to overturn to make its contents fall into the rst hopper member. The emptyingmember and the conveyors 16 and 17 can be ofa traditional type and, therefore, not further described or illustrated. Optionally, the apparatus 10 may e.g. comprise a rst ltering device 27 positioned in such a way that in use it is located above the first hopper member 14a to lter and retain eggshell fragments and allow the passage ofthe shelling product. The unloading device 13 can e.g. comprise a secondhopper member 14b and / or a third hopper member 14c which can be housed in the unloading compartmentU and positioned, with respect to the conveyors 16 and 17, so that when the apparatus is in use they are under conveyors 16 and 17 . The unloading device 13 can be congured to cause the falling of shelling product from the seats ofboth the conveyors 16 and 17 into the second hopper member 14b, to simultaneously collect both the yolk and the albumen together. Moreover, the unloading device 13 can be configured to cause the falling of shelling product selectively from specic seats ofthe conveyors 16 and 17 into the thirdhopper member 14c, to collect waste yolks and / or albumen. In this case, optionally, the selection ofsaid specic seats can be carried out by an operator or by a selection device (e.g. a said controller C), possibly equipped with a viewing system facing said seats, which can be integrated or connected with the unloading device 13 to operate it so as to unload their contents from said specic seats when such content is identied as to be discarded. According to an embodiment, the unloading device 13 can comprise a tank 28 positioned in the unloading compartmentU in such away that in use it is under the rst conveyor 16 to receive the shelling product from the latter.A refrigeration device (not shown) can be provided, thermally connected to the tank 28 to cool it to a temperature not higher than 15°C and preferably between 0°C and 4 C, for example by means of a cooling- jacket with recirculation ofrefrigerant associated with the tank 28. The apparatus 10 can e.g. be configured to unload the shelling product from the first conveyor 16 into a second unloading position G ofthe unloading compartment U. Optionally, the apparatus 10 can comprise a second filtering device 29 positioned in such a way as to receive shelling product from the first conveyor 16 unloaded in the second unloading position G, to lter and retain eggshell fragments and allow the passage of the shelling product. The rst ltering device 27 and / or the second ltering device 29, respectively, can comprise a mesh or perforated conveyor belt which can be operated to drag, in an ejection direction H, J, fragments of eggshell ltered during the operation ofthe apparatus 10. The ejection directionH ofthe first filtering device 27 can e.g. be transversal and preferably perpendicular to the direction ofadvancement M. The ejection directionH ofthe second filtering device 29 can e.g. be parallel to the direction ofadvancementM where the second unloading position G is located at one end ofthe transport device 15 distal to the shelling device 12. The apparatus 10 may also comprise a loading device 33 (see Figures 1-3) congured to load eggs E into the shelling device 12 through an inlet compartmentK ofthe casing 1 1. The inlet compartmentK can be provided at a first end ofthe casing 1 1 where at a second end ofthe same, distal from the rst end with respect to the direction ofadvancement M, an ejection opening can be provided through which the second ltering device 29 can eject waste material from the casing 1 1. Figures 7, 8A, 8B depict part ofanother example ofan apparatus for separating egg liquid. In this case, the apparatus includes a chute 101 (known per se), configured to receive egg liquid B,Y at an upper chute section 125U, and to transport liquid at an angle downwards along a glide path to a lower chute section 125L (see also the alternative example of Figures 9A, 9B).A liquid supplier 150 (e.g. including an egg liquid guide surface) be located between a said egg breaker 12 (not shown in Fig. 7) and the upstream section 125U ofthe chute 101, for transferring liquid contents B, Y ofbroken eggs E (providedby the egg breaker 12) onto the chute 101. At least part ofthe (inclined) chute 101 includes an elongated slit 125b, e.g. extending centrally through the chute, for passage (and downwardly discharging) ofthe albumen B from yolks that are supported on an upper chute surface. For example, the chute 101 can include two parallel chute sections 125a having opposite longitudinal edges dening the albumen passage slit 125b there-between. An albumen receiver 14 (see Fig. 1), or e.g. a hopper member, can be located below the elongated slit 125b, for receiving albumen B that has passed the slit 125b, e.g. for transferring separated albumen to a downstream albumen collector AC. An egg yolk collector (not shown) can be located at the bottom end 125L ofthe chute for collecting yolks that have been transported along the respective chutes glide path, i.e. along the chutes guide surface. Preferably, a widthW ofthe slit 125b ofthe egg liquid separation structure (in this case the chute 10 1) is adjustable. To that aim, for example, one or each ofthe respective chute sections 125a can be movable arranged, to be transversally adjusted between at least a first position and a second position. For example, the widthW ofthe slit 125b is larger when the chute sections 125a are in their second position (see Fig. 8B) with respect to the widthW ofthe slit 125b when the chute sections 125a are in their rst position (depicted in Fig. 8A). For example, the chute 101 can include a chute support structure 125d for supporting or carrying the respective chute sections 125a in a transversally adjustable manner (allowing said slit width adjustment), as will be clear to the skilled person. It is preferred that the egg liquid separation structure includes a controllable slit adjustment device 140 (e.g. a motor, actuator, servo or the- like), for setting the width ofthe slit 125b. The drive 140 can be under control ofthe controller C. Optionally, the chute 101 can include an agitation device 102 for agitating (e.g. shaking or vibrating) at least part of the chute 101. Figures 9A, 9B schematically show side views ofpart ofan alternative embodiment 201 ofan apparatus for separating egg liquid that includes a chute. The example ofFig. 9A, 9B differs from the example shown in Figures 8A, 8B in that an angle ofinclination ofthe chute 225 (i.e. its slope) is adjustable. For example, the chute 225 can be pivotally mounted with respect to an upstream egg liquid supplier 150, e.g. at least between a first angle 61 and a second angle 82 (said angles 61, 62 e.g. being measured between a chutes glide path -the slope- and a horizontal plane P, seen in side view). Preferably, the chutes angle is automatically adjustable. To this aim, the chute 225 can be a connected to a controllable drive 240 (e.g. a motor, actuator, servo or the-like), configured for pivoting the chute 225 to a desired angle (i.e. for setting a slope ofthe chute). The drive 240 can be under control ofthe controller C. As is mentioned before, the egg liquid separation structure 1, 101 ofthe apparatus is congured to separate albumen B and yolkY ofreceived egg liquid using one or more adjustable egg liquid separation parameters. In particular, such an adjustable egg liquid separation parameter concerns egg liquid separation action ofthe structure 1, 101. For example, increasing an egg liquid separation parameter can lead to increasing a driving force to separate the albumen B from the yolk (as carried out by the egg liquid separation structure 1, 101), and / or it can lead to decreasing or reducing a barrier for the albumen B to leak away from the yolk Y. Similarly, for example, decreasing an egg liquid separation parameter can lead to decreasing a driving force to separate the albumen B from the yolk (as carried out by the egg liquid separation structure 1, 101), and / or it can lead to increasing or enhancing a barrier for the albumen B to leak away from the yolk Y. For example, the separating ofthe albumenB from the yolkY can include agitating the egg liquid separation structure 1, 101 containing or supporting the egg liquid to be separated (the agitating carried out by a respective agitation device 2, 102), using one or more shaking parameters, for example a shaking frequency and / or shaking velocity, wherein at least one shaking parameter can be adjustable. Generally, increasing the shaking or vibration can enhance separation ofthe albumenB from the yolk Y, and decreasing the shaking or vibration reduces the respective separation enhancing effect. In addition or alternatively, the separating ofthe albumen B from the yolkY can include blowing pressurized air (by a respective blowing device 3) towards the egg liquid using one or more air blowing parameters (e.g. airow rate, air velocity), wherein at least one ofthe air blowing parameters can be adjustable. Generally, increasing such an air blowing parameter can enhance separation ofthe albumenB from the yolk Y, and decreasing the air blowing parameter reduces the respective separation enhancing effect. Also, as follows from the above, the separating ofthe albumen B from the yolkY can include sliding the respective liquid along a chute structure 101, wherein at least one chute structure parameter ofthe chute structure 101 (e.g. a widthW of a chute slit 125b) can be adjusted (e.g. via a respective drive 140, under control ofthe controller C) based on the predeterminedinformation. Generally, increasing the widthW ofthe slit 125b can enhance separation ofthe albumenB from the yolk Y, and decreasing the widthW ofthe slit 125b reduces the respective separation enhancing effect. Besides, as is mentioned before, a speed of an egg liquid conveyor 15 (ifany) can be adjustable, the speed also being an egg liquid separation parameter. In particular, lowering the speed ofthe egg liquid conveyor 15 (from an initial conveyor speed) provides increase ofprocessing time, i.e. more time for albumen B to separate from yolkY in the apparatus. Similarly, referring to Figures 9A, 9B, generally, increasing the slope ofa egg liquid separation chute 225 (as liquid separation parameter) can lead to an increase ofliquid glide velocity and a resulting change in liquid separation performance. Preferably, the apparatus includes at least one egg liquid evaluation device 4a, 4b, 4c, 4d, 4e configured to evaluate a result ofthe separating ofthe albumenB from the yolkY and to generate corresponding evaluation result information. The controller C is congured to receive and process said evaluation result information for subsequent adjusting ofone or more egg liquid separation parameters. According to an embodiment, the apparatus includes or is associated with one or more one egg liquid evaluation devices 4a, 4b, 4c, 4d, 104. One or more egg liquid evaluation devices 4a, 4b, 4c, 4d can be congured to detect a result ofan egg liquid separation process, carried out by the separation structure. For example, the egg liquid evaluation device can include at least one detector 4a, 4b, 4c, 4d for detecting a physical characteristic ofthe yolk Y, ofthe albumen B, or ofboth yolkY and albumen B. As is indicated in Figure 1, the detector can be located in various positions, in particular downstream ofthe egg breaker 12 and for example at, near or downstream ofthe egg separation structure 1. For example, a detector 4a can be located in, at or near a respective yolk collector YC, for evaluating yolk received in the yolk collector YC. For example, a detector 4b can be located in, at or near a respective yolk discharge port 36, for evaluating yolk owing to or through the port 36. For example, a detector 4c can be located in, at or near a respective albumen collector AC, for evaluating albumen received in the albumen collector AC. For example, a detector 4d can be located in, at or near a respective albumen discharge port 35, for evaluating albumen owing to or through the port 35. It will be appreciated that a said detector 4a, 4b, 4c, 4d for detecting a physical characteristic ofthe egg liquid (yolk and / or albumen) can also be located at different positions ofthe apparatus. Various physical characteristics ofthe egg liquid Y, B can be used, i.e. be detectedby a said detector 4a, 4b, 4c, 4d. For example, a detector 4a, 4b for detecting yolk characteristics can be congured to detect one or more of: - a viscosity ofthe yolkY (i.e. by a viscosity sensor); - a temperature ofyolkY (i.e. by a temperature sensor); -a dry matter content ofthe yolkY (i.e. by a dry matter sensor); -apH value ofthe yolkY (i.e. by apH sensor); -aow characteristic ofthe yolkY (i.e. by aow characteristic sensor, e.g. a mass ow sensor). For example, a detector 4c, 4d for detecting albumen characteristics can e.g. be congured to detect one or more of: -an optical density ofthe albumen (e.g. an optical density sensor); - a viscosity ofthe albumenB (i.e. by a viscosity sensor); - a temperature ofthe albumen B (i.e. by a temperature sensor); -a dry matter content ofthe albumen B (i.e. by a dry matter sensor); -apH value ofthe the albumen B (i.e. by apH sensor); -aow characteristic ofthe the albumen B (i.e. by aow characteristic sensor, e.g. a mass ow sensor). Moreover, one or more detectors can be provided to detect one or more physical characteristic ofegg liquid containing a mixture ofyolk and albumen (e.g. in case whole egg liquid is produced). It will be appreciated that various types of detectors (e.g. respective sensors) can be combined or installed in the apparatus, to detect various types ofphysical egg liquid characteristics. In addition or alternatively, the apparatus can be congured to detect a broken yolk ratio. For example, the apparatus can include a sensor 4e (see Fig. 1), e.g. a camera, for examining yolk contents of a yolk conveyor, wherein respective sensor detection results ofthe sensor 4e can be processed (e.g. by the controller C) to determine if a cup 25a contains an unbroken (whole) yolkY or broken yolk, before the yolk is discharged towards a yolk outlet 36. The respective processing (e.g. by the controller C) can then e.g. determine the broken yolk ratio (i.e. a detectednumber ofbroken yolks divided by a total number of detected yolks). The controller C can be communicatively coupled to the one or more detectors 4a, 4b, 4c, 4d, 4e for receiving respective detection results thereof, e.g. via wired and / or wireless communication links, a will be clear to the skilled person. Advantageously, the controller C is configured to receive predetermined information and to automatically adjust at least one ofthe one or more egg liquid separation parameters based on the received predetermined information. For example, the controller C can be communicatively connected to at least part ofthe egg liquid separation structure 1, 101 (e.g. via a suitable communication link, a wired or wireless control signal line and / or the-like) to automatically adjust a respective egg liquid separation parameter. According to an example, the controller C can be congured to control a said blowing device 3, to adjust (e.g. change) a respective air blowing parameter, based on saidpredetermined information. According to an example, the controller C can be congured to control a said agitating device 2, 102 to adjust (e.g. change) a respective egg liquid agitation parameter, based on saidpredetermined information. According to an example, the controller C can be congured to control a said egg liquid conveyor 15, to adjust (e.g. change) a respective egg liquid conveying speed, based on said predetermined information. According to an example, the controller C can be congured to control a said chute structure 101, to adjust (e.g. change) a respective chute slit width W, based on saidpredetermined information. The controller C ofthe apparatus can be configured in various ways. For example, the controller C can be a central control unit, a computer, hardware and / or software, in particular congured (e.g. programmed) to provide above-mentioned control functionality during controller operation, as will be appreciated by the skilled person. Further, the controller C can include a (digital) memory for storing said predetermined information. For example, the controller C can include or be associated with an information receiver IR configured for receiving detection results from the one or more detectors 4a, 4b, 4c, 4d 4e as predetermined information. Alternatively or in addition, the controller C can be congured to receive predetermined information (e.g. via an information receiver IR) from an external information provider 104 (see Figure 1). Such an information provider 104 can be a user interface, a remote information provider, an information server and / or the like, and can e.g. be communicatively coupled to the controller via a communication link (e.g. user interface link, a computer network, Internet and / or the like). The external information provider 104 can in particular be congured to provide predetermined information that is or includes specic information relating to the eggs E (i.e. egg origin information) before breaking (i.e. the eggs E that are fed to the apparatus, towards the respective egg breaker 12). Such predetermined egg origin information can for example include one or more of: - egg age information egg laying date information concerning the egg E; -egg farm information and / or poultry house information concerning the egg E; and -avian specic information concerning the egg E. Such predetermined egg specific information can be received by the controller C (via the information receiver IR), to be processedby the controller C. The controller C can automatically adjust (e.g. change) a said egg liquid separation parameter based on this received specific information relating to the eggs E before breaking. Optionally, e.g., the controller C can be configured to use data or a database (which can e.g. be stored in a memory ofthe controller C) for associating egg origin information with one or more respective egg liquid separation parameters. For example, such data can include a look-up table, including a list ofentries of (known) egg origin information (e.g. concerning different farms and / or different avian types) linked to one or more specific egg liquid separation parameters that are to be used by the apparatus for processing eggs having the respective egg origin. Operation c.q. use ofthe apparatus can provide a method for separating egg liquid, in particular for separating yolkY and albumen B. During use, the apparatus can provide / process egg liquid, containing yolkY and albumen B, from broken eggs E (broken by the breaking device 12). The apparatus can separate the albumen B from the yolkY ofeach eggE using one or more adjustable egg liquid separation parameters (as mentioned above). Advantageously, at least one ofthese egg liquid separation parameters is automatically adjusted (by the controller C) based on afore- mentioned predetermined information. In this way, optimum egg liquid processing can be achieved. In particular, the controller C can automatically adjust one or more egg separation during operation, depending on the predetermined information, to optimize quality (e.g. purity) of generated yolkY and separated albumen B, i.e. to reduce chances that part ofalbumen B is not separated from yolkY and is undesirably fed to a yolk collector YC. Repeating the above, such predetermined information can include specic information relating to the eggE before breaking by the breaker 12, for example one or more of: egg age information egg or a laying date information concerning the egg E; egg farm information and / or poultry house information concerning the egg E; and avian specific information concerning the egg. The controller C can automatically associate such predetermined information with the one or more egg separation parameters. For example, it has been found that the age ofan egg can inuence the liquid contents ofthe egg, as well a resulting action required to separate a respective yolkYfrom respective albumen B. In particular, a relatively fresh (young) eggE (e.g. younger than 10 days) can have a relatively strong yolkY that can withstand signicant shaking and relatively strong air streams (without breaking the yolk Y). The controller C can therefore be congured to control a respective agitating device 2, 102 and / or air blower 3 to achieve significant shaking and / or a relatively high airow rate, to process liquid that been obtained from that egg E, in case respective egg specic information indicates that the eggE has a relatively young age. Similarly or alternatively, in case ofthe apparatus having a chute structure 101 that includes an adjustable slit, the controller C can be configured to control the chute structure 101 to provide a relatively large slit width W (see Fig 8B) in case ofprocessing liquidfrom such relatively young eggs E. Alternatively, in case ofan adjustable slope (see Figures 9A, 9B), the controller C can be configured to control the respective chute structure 201 to provide a relatively large chute slope 82 (see Fig. 9B) to achieve relatively high liquid glide velocities to process such liquid. On the other hand, a relatively old eggE (e.g. older than 10 days) can have a relatively weak yolkY that cannot withstand significant shaking or relatively strong air streams. The controller C can therefore be congured to control a respective agitating device 2, 102 and / or air blower 3 to achieve no or only a litter shaking and / or a relatively low (or no) airow rate, to process liquidhas been obtained from that egg E, in case respective egg specic information indicates that the eggE has a relatively old age. Similarly or alternatively, in case ofthe apparatus having a chute structure 101 as egg liquid separation structure, the controller C can be configured to control the afore-mentioned chute structure 101 to provide a relatively small slit widthW (see Fig. 8A, i.e. a widthW that is smaller than said large slit width W) in case ofprocessing liquidfrom such relatively old eggs E. Alternatively, in case ofan adjustable chute slope (see Figures 9A, 9B), the controller C can be configured to control the respective chute structure 201 to provide a relatively small chute slope 61 (see Fig. 9A) to provide relatively small liquid glide velocities to process such liquid. The same holds for other types ofpredetermined egg specic information, in particular egg origin information, for example the egg farm information and / or poultry house information concerning the egg E, and the avian specic information concerning the egg. It has been found that different egg farms or poultry houses can generate mutually different types ofeggs that can require different egg processing parameters. Also, different types of avians (e.g. different breeds) can generate mutually different types ofeggs that can require different egg processing parameters. The controller C can be configured to associated such information with one or more egg separation parameters used by the apparatus (e.g. via an afore-mentioned database or look-up table), and e.g. automatically change one or more egg separation parameters in case of a change of a type ofthe origin ofthe eggs E fed to the apparatus based on egg farm or poultry house or avian type. It will be appreciated that saidpredetermined information can e.g. be stored or heldby a remote information provider, and can be sent to the controller C via a respective information receiver IR, or differently as will be clear to the skilled person. For example, a batch ofeggs E that is being fed to the apparatus (e.g. to a respective egg supply conveyor 33) can be provided with such predetermined information, e.g. on a data carrier, a readable code or label, wherein the information provider 104 or information receiver IR can e.g. include a reader congured to obtain the predetermined information from the batch ofeggs (e.g. by reading a respective data carrier, a readable code or label). In addition or alternatively, the predetermined information used can relate to an earlier result ofegg breaking process as such. To that aim, the method can include processing a plurality ofeggs E, including breaking each eggE for providing egg liquid containing yolkY and albumen B, the method further including: -separating the albumenB from the yolkW from at least one rst broken egg (e.g. from a batch or plurality ofrst eggs); -automatically evaluating a result ofthe separating ofthe albumen B from the yolkY ofthe at least one rst broken egg (e.g. by an aforementioned sensor 4a, 4b, 4c, 4d, 4e) and generating corresponding evaluation result information concerning the separating ofthe at least one first broken egg. The controller C can then automatically adjust at least one ofsaid one or more egg liquid separation parameters based on the generated evaluation result information concerning the separating ofthe at least one first broken egg. Subsequently, the apparatus can separate albumen B from yolk Y, from at least one second broken egg (e.g. a batch ofsecond eggs), using the one or more adjustable egg liquid separation parameters with at least one ofthese parameters being adjusted based on the evaluation result information concerning the separating ofthe at least one rst broken egg. Thus, the apparatus can automatically adjust one or more ofthe egg liquid separation parameters to process a number of (second) eggs E, based on evaluating an outcome ofthe separating ofegg liquid ofa number of (first) eggs that have been processed earlier. Then, in particular, the automatically evaluating ofthe result of the separating ofthe albumen B from the yolkY ofthe at least one first broken egg preferably includes measuring (e.g. by a said sensor 4a, 4b, 4c, 4d) at least one physical characteristic ofthe yolk and / or albumen, for example at least one physical characteristic selected from: - a viscosity ofthe yolkY and / or albumen B; - a temperature ofthe ofthe yolkY and / or albumen B; -a dry matter content ofthe yolk Y; -an optical density ofthe albumen B; -apH value ofthe yolkY and / or albumen B; and -aow characteristic ofthe yolkY and / or albumen B. In addition or alternatively, the automatically evaluating ofthe result ofthe separating ofthe albumen from the yolkY ofthe at least one first broken egg can include determining a broken yolk ratio, as is mentioned before. In addition or alternatively, the egg liquid can be transported at a certain transport velocity (by a respective conveyor 15) along a transport path during the separating ofthe yolk and albumen, wherein the transport velocity can be automatically adjusted by the controller C based on said predetermined information. In this way, optimum egg liquid separation can be achieved, in particular in an efcient and highly automated manner, leading to improved reliable egg liquid separation results. It is self-evident that the invention is not limited to the above- described exemplary embodiments. Various modifications are possible within the framework ofthe invention as set forth in the appended claims. In this application, the eggs to be processed are in particular non- living, dead eggs, i.e. eggs for consumption that are not fertilized (and do not contain any embryo). The avian / bird eggs can be poultry eggs, for example chicken eggs. The afore-mentioned predetermined information is in particular information that has been determined before the egg liquid ofan egg is being separated (by the egg liquid separation structure), as will be clear to the skilled person. Determining c.q. providing predetermined information (in particular egg origin information and / or egg age information) can e.g. be carried out in various ways, for example by an operator or personnel ofan egg laying production facility (e.g. an egg farm or a poultry house thereof), to be entered via an information receiver, and / or automatically by an egg specic information generator ofthe respective egg production facility (which can e.g. be a date or time generating system that automatically generates egg laying date information or egg laying time information concerning the eggs that are produced in the egg production facility, wherein the generated information can be -e.g. automatically- supplied to the information receiver to be used in the processing ofthose eggs), and / or differently. According to an embodiment, the predetermined information can be stored and / or provided on an information carrier, for example an analogue or digital information carrier. According to an embodiment, the predetermined information can be stored and / or providedby an electronically readable information carrier for example a digital information carrier, a readable code, QR-code, bar-code, datamatrix code, RFID-tag. According to an embodiment, in case ofsupplying a plurality (e.g. a batch) ofeggs E that is to be processed (i.e. broken and subsequently liquid separation), a respective information carrier can be attached or coupled to a carrier that carries or holds the plurality ofeggs (the carrier e.g. being a crate, a pallet, an egg box, an egg tray, or a combination ofsuch carrier structures). For example, according to an embodiment, a said information carrier can be read during the processing ofthe eggs, for obtaining the respective predetermined information, to be subsequently used by an egg liquid separation structure. To that aim, the egg liquid separation structure can include an information receiver including a reader device for reading the information carrier. Alternatively or additionally, ahuman operator can assist in the reading ofthe information carrier (e.g. using a manually operable reader).
