    专利说明:

    The present invention relates to a freezing plant of the type in the preamble of claim 1, with a first vertical plate freezer and a second vertical plate freezer, which second vertical plate freezer is located after the first plate freezer in a longitudinal direction, forming a space, wherein each vertical plate freezer has an upper frame part with a number of longitudinally arranged downwardly open freezing chambers for freezing a content, such as fish, and a lower frame part arranged below the upper frame part, with i) an endless conveyor with a longitudinally movable upper conveyor surface and ii) a movable freezer bottom arranged to be able to close all the freezing chambers downwards in a first position of the freezer bottom, and which is adapted to be able to move longitudinally towards a second position below the conveyor for en route to allow successive downward emptying of the said contents onto the upper conveyor surface for conveyance; longitudinal contents, where for each vertical plate freezer the relative vertical position of the upper frame part and the lower frame part can be varied between a freezing position in which the freezer bottom in its first position closes the freezing chambers downwards and an emptying position in which the freezer bottom in its leading position position is at a vertical distance below the freezing chambers.
    Such a freezing system is described in European patent EP 1043555. In connection with such known freezing systems, there is a need to be able to - transport the frozen material to, for example, a packaging station with a few conveyors.
    FIG. 5 of the aforementioned patent shows a freezing plant with two vertical plate freezers placed one after the other.
    However, the patent does not indicate how the frozen material can be conveyed from the first vertical plate freezer in the conveying direction while the contents of the subsequent vertical plate freezer are being frozen, and it is thus an object of the invention to provide an improved freezing plant of the aforementioned kind. , with which
    DK 2019 70364 A1 2 that frozen content can be continued in a reliable manner from the first vertical plate freezer, regardless of whether it is frozen in the subsequent one. This object is solved according to the invention in that the freezer bottom of the second vertical plate freezer in its first position is at a distance above the upper conveyor surface of the endless conveyor of the second vertical plate freezer, for conveying on this upper conveyor surface exhausted contents from the first vertical cold plate freezer, and that the freezing plant comprises a further conveyor arranged to be movable between a) an active position, where it forms a bridge over the aforementioned space in order to be able to continuously continue said emptied contents away from the conveyor of the first vertical plate freezer and up to the conveyor of the second vertical plate freezer, and b) an inactive position, where the additional conveyor allows movement of the freezer bottom of the second vertical plate freezer from its first position to its second position.
    Advantageous embodiments appear from the dependent claims. Brief explanation of the drawings Figs. 1a and 1b show an embodiment of a freezing plant according to the invention, seen respectively. from the side and from above, and while emptying a vertical plate freezer shown on the right, Figs. 2a and 2b show a partial section on a larger scale of the area at the transition between those in fig. 1a and 1b showed two vertical plate freezers, seen respectively. from the side and in perspective, with a further conveyor between the two vertical plate freezers in its inactive position, Figs. 3a and 3b show the freezing plant in fig. 1a and 1b, set respectively. from the side and from above, and while emptying the vertical plate freezer shown on the left, and
    DK 2019 70364 A1 3 Fig. 4a and 4b show a partial section on a larger scale of the area at the transition between those in fig. 3a and 3b showed two vertical plate freezers, seen respectively. from the side and in perspective, with the additional conveyor in its active position. Detailed description of an embodiment In fig. 1a and 1b are respectively. from the side and from above shown a freezing system 1 comprising a first elongated vertical plate freezer A and a second elongated vertical plate freezer B, the second vertical plate freezer B being located in immediate extension of - the first vertical plate freezer A, seen in the marked longitudinal direction L. To the right of the second vertical plate freezer B may be arranged a conveyor (not shown) with a conveying direction in the plane of the drawing or out of the plane of the drawing. The freezing plant 1 can, for example, be located on board a ship, such as a fishing vessel.
    The vertical plate freezers A, B may be of the type described in EP 1043555, and reference is thus made to this patent specification for a more detailed explanation of the procedure which can be followed when freezing contents, such as fish F, which have been filled from above. in a series of longitudinally longitudinally located L-freezing chambers 20, which form part of each vertical plate freezer A, B. Since the two vertical plate freezers A, B will typically be the same, the following explanation applies to both the two vertical plate freezers A, B. The freezer system provides blocks of frozen contents that can subsequently be packaged.
    The vertical plate freezers A, B each comprise an elongate upper frame part 10 with the freezing chambers 20, as well as an elongate lower frame part 30 arranged below this upper frame part 10 with legs 2 for placing the vertical plate freezers A, B on a floor (not shown). For each vertical plate freezer A, B, the relative position in the vertical direction of the upper frame part 10 and the lower frame means 30 can be varied between a freezing position shown for the vertical plate freezer.
    DK 2019 70364 A1 4 A to the left in fig. 1a, and an emptying position shown for the vertical plate freezer B on the right in fig. 1a, where the two frame parts 10, 30 are separated from each other by a distance D1. The movement in the vertical direction can be provided, for example, by means of a piston arranged in a pressure cylinder 5.
    The lower frame part 30 comprises between its ends and as shown most clearly | fig. Fig. 2a shows an endless belt conveyor 45, which is driven by a drive roller 44 located at one end of the lower frame part 30, and which has an upper conveyor surface 47 which, when suitably activated by the belt conveyor 45, moves in the longitudinal direction L. Figs. 2a is a cross-section along the line Z-Z in fig. 1b. The lower frame member 30 also includes a movable, elongate freezer bottom 35 having a relatively smooth surface adapted to extend generally in a first position in a horizontal plane over the upper conveyor surface 47. | this - first position closes the freezer bottom 35 all freezing chambers 20 downwards. The freezer bottom 35 is in this first position, while the freezing of the contents F takes place in the freezing chambers 20 with the frame parts 10, 30 in the freezing position, until the frozen contents F can be emptied out when the frame parts 10, 30 are moving to the emptying position. The said first position of the movable freezer bottom 35 is for the first vertical plate freezer A shown on the left in fig. 1a, where the frame members 10, 30 are in the freezing position. The freezer bottom 35 consists of a number of interconnected slats 36 and is - arranged to be able to move in the direction of the longitudinal direction L in the aforementioned horizontal plane towards another position, where the freezer bottom 35 is inverted by activating a drive wheel 32. below the endless conveyor 45. The freezer bottom 35 can thus be connected along its opposite longitudinal side edges to a chain or the like as a precursor - around the drive wheel 32 and a corresponding wheel arranged at the other end of the vertical plate freezer B.
    DK 2019 70364 A1 Along each of the 30 sides of the lower frame part, guides 31 are arranged, which guide the freezer bottom 35 during this movement. | fig. 2a and 2b show how the drive wheel 32 successively grips the slats 36 when the drive wheel 32 is rotated in the direction shown by the arrow to guide the freezer bottom 35 towards its second position during the transport of the vertical plate freezer 45. | fig. 1a, for the vertical plate freezer B on the right, the freezer bottom 35 is shown on its way to its second position. When the freezer bottom 35 is finally in its second position, it applies that from left to right, as clearly seen in fig. 4b is free access to the upper conveyor surface 47, for the purpose described below.
    When the freezer bottom 35 is in its first position and the frame means 10, 20 are in the emptying position, the freezer bottom 35 is in the aforementioned vertical distance D1 below the downwardly open freezing chambers 20, with the blocks of the frozen contents F partially dropped out of the freezing chambers 20 for abutment against the - underlying freezer bottom 35, for example as a result of the procedure described in EP 1043555. When the freezer bottom 35 is at this time moved towards its second position opposite the longitudinal direction L, i.e. to the left of the drawings, a successive downward emptying of the said content F takes place out on the upper conveyor surface 47 for thereby conveying the content F in the longitudinal direction L, i.e. to the right in the drawings, in principle in the same way as described in EP 1043555. The freezer bottom 36 thus preferably has at the end a ramp 38 which can be turned downwards towards the conveyor surface 47, so that the frozen blocks of the contents F can successively slide down the last piece out of a respective freezing chamber 20 and come to lie horizontally on the part of the conveyor surface 47 exposed by the movement of the freezing bottom 36 towards its second position. Because there must be room for the path of movement of the freezing bottom 35 of the second vertical plate freezer B between the two vertical plate freezers A, B according to the invention, it is not possible to place the two vertical plate freezers A, B so that their respective conveyor surfaces 47 are completely close to each other. This
    DK 2019 70364 A1 6 problem is typically non-existent at the opposite end of the second vertical plate freezer B, where the blocks F are passed on from the freezing plant 1, because the freezing bottom 36 does not move down along this end. In order to now be able to continue the longitudinal blocks L of the frozen contents F from the first vertical plate freezer A while the contents F are being frozen in the second vertical plate freezer B, the freezing plant 1 according to the invention comprises a further conveyor 60 arranged in an active position shown in fig. . 4a and 4b, to bridge the space M between the two vertical plate freezers A, B. In this active position, the further conveyor can move the blocks F over to the conveyor surface 47 of the second vertical plate freezer B, after the freezer bottom of the second vertical plate freezer B 35 is led to its second position, or alternatively when the freezer bottom 35 of the second vertical plate freezer B is completely in its first position, whereby, as mentioned, there is - access from the left to the conveyor surface 47 of the second vertical plate freezer B.
    In figs. 2a and 2b, the further conveyor 60 is shown in its inactive position, in which it allows movement of the freezer bottom 35 of the second vertical plate freezer B from its first position towards its second position via the space M, - emptying the second vertical plate freezer B in the manner described above, where the freezer bottom 35 is moved from its first position. When the emptying of the vertical plate freezers A, B is completed, the respective freezer bottoms 35 are returned to their first position.
    It will be appreciated that in order to allow conveying on the underlying conveyor surface 47 of the second vertical plate freezer B of the discharged contents F from the first vertical plate freezer A while the frame parts 10 of the second vertical plate freezer B are in the freezing position, cf. fig. 3a, the freezer bottom 35 of the second vertical plate freezer B is arranged so that in its first position it generally extends in said horizontal plane at a distance D2 above the underlying
    DK 2019 70364 A1 7 conveyor 45 upper conveyor surface 47, corresponding to at least the thickness of the blocks, as shown in fig. 4a, i.e. forming the passage shown in the drawing with P.
    It will further be understood that the freezing plant may comprise a control system arranged to automatically control movement of the further conveyor 60 in accordance with the operations carried out with the two vertical plate freezers A, B so as to ensure that the further conveyor 60 does not collide with the movable freezer bottom 35 of the freezer B when the freezer bottom 35 is moved to a position wholly or partly below the conveyor 45.
