A cutting apparatus for cutting an essentially V-shaped strip from meat products fed in a transport direction has a knife carrier to which two knife units are assigned. Each knife unit has a circular knife and a drive for rotationally driving the circular knife about a central axis of rotation. The two circular knives are set substantially in a V-shape to each other in a position enclosing an angle. An adjustable arrangement of the knife units provides for setting of the size of the angle. The offset of the two central axes of rotation to each other is equal to zero in the transport direction and the two knife units are adjustable exclusively synchronously with each other. A corresponding apparatus and method for cutting an essentially V-shaped strip from meat products fed in transport direction is also provided.

The invention provides a fish processing device for cleaning blood and blood vessels from the spine of a fish, e.g. a salmon, after the visceral has been removed. A jet nozzle for spraying pressurized liquid and a movable suction device with a vacuum nozzle for entering the abdominal cavity of the fish serve in combination to clean the spine of the fish for blood and blood vessels. A controller controls an actuator for moving the vacuum nozzle to enter the abdominal cavity of the fish, and it is then moved in a first direction relative to the transport direction, until the first vacuum nozzle reaches an end of the abdominal cavity of said fish while sucking blood and blood vessels from the abdominal cavity along the spine of said fish. This is repeated by moving the vacuum nozzle in the opposite direction until reaching an opposite end of the abdominal cavity of said fish, where the vacuum nozzle exits the abdominal cavity. Preferably, the fish is continuously transported along with this cleaning process. Some embodiments comprise a second set of jet nozzle and suction device mounted downstream of the fish transport direction to allow even further cleaning of blood and blood vessels along the spine of the fish.

A method is used in the production of principal products conveyed in plurality along a processing line, consisting of fish, poultry or other meat which contains, in addition to the principal products to be obtained, inedible components to be removed (removal components) and also contains edible by-products remaining on said removal components. The edible by-products remain on the removal components after removal. The method includes: loading a separating device with a batch of fish, poultry or other meat; separating the principal products of this batch from the removal components, comprising by-products, of said batch; separating the by-products from the removal components; producing a by-product brine from the by-products by comminuting the by-products and mixing with water and stabiliser; and injecting a defined quantity of the by-product brine into the principal products, wherein principal products and the by-products contained in the by-product brine come from the same batch.

The invention provides a gutting device for gutting a fish along its abdominal cavity. A blade for cutting the fish open, and a shielding element are movably mounted on a controllable movable arm. The shielding element has a blunt tip, and it is arranged for being in: 1) a retracted position, where the shielding element allows the blade to cut the fish, 2) a tracking position, where the blunt tip of the shielding elements is inside the abdominal cavity of the fish, so as to track the end of the abdominal cavity of the fish, and 3) a shielding position, where the shielding element is pushed upwards by contact with the end of the abdominal cavity at a genital opening of the fish, thereby shielding the blade from further contact with the fish. This provides a precise method for without unintentionally damaging the fish.

A bleeding method for a fish includes step of forming a slit SL that connects pericardial cavity 11 to an outer part of the fish by cutting membrane 16 to split a head and an abdomen such that abdominal aorta 19 is not cut and internal organs incorporated in abdominal cavity 12 are not exposed to an outside air, step of spreading the slit such that arterial sphere 18 does not tomozure, and a caudal side surface of ventricle 171 is exposed, step of inserting tubular instrument 2 in heart 17, which runs through the spread slit SL from the caudal side surface of the ventricle toward arterial sphere 18, step of fixing tubular instrument 2 to heart 17, and step of discharging blood of the fish outside by press-fitting liquid into vascular system of the fish via tubular instrument 2.

A portable fish cleaning assembly includes a platform that has a drink aperture, a tool aperture, a plurality of hook apertures and a pair of storage holes each extending therethrough. A pair of grapples is each removably coupled to the platform. Each of the grapples releasably engages a top pier rail having the platform being horizontally oriented on the top pier rail. In this way a fish can be positioned on the platform for filleting the fish. A pair of legs is each pivotally coupled to the platform. Each of the legs extends downwardly from the platform when the legs are positioned in a deployed position. In this way each of the legs abuts horizontal pier rails thereby retaining the platform in the horizontal orientation. A clamp is pivotally coupled to the platform to engage the fish for retaining the fish on the platform for filleting the fish.
