Abstract: The invention relates to an egg breaking apparatus and a method of feeding eggs to an egg breaking apparatus, where eggs are fed to a plurality of egg breaking devices by means of a feed conveyor. Each egg breaking device receives one egg at a time and all egg breaking devices are mounted on a common drive conveyor, where the egg breaking devices are moved in relation to the feed conveyor in a first direction following a substantially vertical first axis at the area of the feed conveyor. The feed conveyor feeds eggs to the egg breaking devices along a substantially horizontal second axis. When near a position at the feed conveyor, the egg breaking devices are tilted about a third axis, which is substantially perpendicular to the first and second axes, in a second direction substantially opposite to said first direction.

Abstract: The invention relates to a method and an apparatus for monitoring the breaking of eggs. The eggs are fed to a plurality of egg breaking devices by means of a feeder, each egg breaking device receiving one egg at a time, whereupon the shell of each egg are broken by means of the respective egg breaking device and the contents of each egg are collected in an egg receiving device, each egg receiving device receiving the contents of only one egg in each process cycle. The remains held by each egg breaking device after the breaking of the eggshell are discharged to a waste receptacle, and the contents of the egg receiving device are discharged into one or more product receptacles. The monitoring consists in that the presence of at least one of the conditions (a) the egg is dropped, (b) eggshell is unbroken or (c) yolk membrane is broken is registered automatically, and that the presence of an abnormality in the egg-breaking is presented to an operator.

Abstract: A centrifuge for draining washed egg trays comprises a centrifuge chamber in a housing (9). A bottom (8) for receiving a washed stack (7) of egg trays in a feeding position is displaceable with respect to said housing (9) between the feeding position and a centrifuging position. The stack (7) of egg trays is centred on the bottom in the centrifuging position, and in this position the bottom is in engagement with a rotational drive (22, 23), which is vertically non-displaceable with respect to the housing.

Abstract: A destacking apparatus has a number of lifting devices (10) for mechanical destacking of egg trays. Each lifting device comprises a carrier part (27) with at least one gripper unit (20, 21) having an abutment (22) and a gripper means (25). The abutment and the gripper means are mutually spaced in the destacking direction. The gripper means (25) is movable transversely to the destacking direction in relation to the abutment, and the gripper unit (20, 21) is movable in the destacking direction in relation to the carrier part (27).

Abstract: A machine for washing eggs (1) has a washing section with spray nozzles (23) and with a brush frame (12) carrying brushes facing down towards the conveyor and having an underside profiled according to the egg shape. The brush frame is suspended in a stationary machine frame and may be actuated by a drive (30,38) for reciprocating movement in both the longitudinal and the transverse directions of the conveyor so that the brushes are moved in a curved movement in relation to the conveyor and thus also in relation to the eggs, which results in a thorough cleansing of, particularly, the end areas of the eggs.

Abstract: An egg processing machine comprises egg breaking units positioned above egg collecting units and an albumen recovery device. The units are moved in pairs with a vertical distance between the two units through an egg breaking section where the egg breaking unit breaks the egg shell and albumen and yolk fall down in the egg collecting unit. An albumen recovery device comprises a rotating body catching albumen drippings with possible stringers before the egg shell is discharged.

Abstract: A feeding apparatus for transferring eggs from a pile of egg trays to an egg depositing position on a supply conveyor of an egg processing machine comprises at least three units which each comprise lifting and retaining heads for lifting all eggs from an egg tray and transferring the eggs to the depositing position and releasable grapplers for transportng the egg trays. The units move in a closed path between a first operational position where a pole of egg trays is located, a second operational position where emptied egg trays are received and a third operational position where the egg depositing position is located. The units are vertically movable at each of these operational positions between an operational level and a conveyance level. The grappler releases retained egg trays at the second position of operation, whereas the units retain the eggs for transfer to the egg despositing position.

Abstract: In an apparatus for the breaking of eggs and separation of yolk and albumen, and of the kind comprising a supply conveyor, a washing and flushing system and a breaking mechanism positioned at one end of the conveyor and having a considerable number of egg stations each capable of receiving and holding one egg at the time, and with separate containers of yolk and albumen, the eggs stations are arranged for successively passing the conveyor to receive eggs and continue through a closed path along which working stations are provided for control of the separation of yolk and albumen, their collection in separate ducts or containers and removal of empty egg shells.

Abstract: An apparatus for shelling boiled eggs is adapted to crackle the egg shell in a first section by impact action for a certain period and to subsequently transfer the egg to a second section, in which the egg shell fragments are cleared from the egg body. The first section includes a tubular egg positioning member with an upper opening and a lower opening which during the crackle action are positioned above two shafts rotatable in the same direction of rotation. The second section comprises a conveyor belt and a retainer roller mounted in spaced relationship from a cylinder, the roller and the cylinder being rotatable about substantially parallel axes of rotation and being capable of contacting the upper side of the conveyor belt. The apparatus is capable of shelling the eggs without causing damage thereto, even though the eggs are only light-cooked, i.e. so-called "smiling" eggs.
