Abstract

A device for shelling shrimps has a long conveyor belt, the upper surface of which is inclined on both sides from the centre line outwards, a number of horizontal slots forming grading openings increasing in size progressively in the direction of motion, assigned to the grading openings and inclined outwards and downwards from the conveyor belt, a number of shrimp aligning chutes each of which blends into a funnel, compressed air leads each of which opens into a curved tip near the outlet of the funnel, roughly at a tangent, and at the outlet of the funnel, a shelling channel with a shell slitter the teeth of which project pike jaw style forming with the shell stripper an oval channel corresponding to the cross section of the shrimp.

Description

BE SC HREIBUN Beschreibung zu Blatt (1) und Blatt (a) der Zeichnung (1) Der Technischevortschritt liegt darin weil bisher mit der Hand geschält wurde.Die vom Förderband zur Sortierung geförderten Krabben,werden durch den Sortierungschlitz Skitze (1) nach größe sortiert,zuerst.die kleinen,die mittelgroßen, und zu letzt die großen.Das Sortierförderband förder die Krabben an den Sortierungschlitz vorbei und die Krabben fallen durch den Sortierungschlitz.BE SC HREIBUN Description of sheet (1) and sheet (a) of the drawing (1) The technical progress lies in the fact that up to now the peeling has been done by hand Crabs transported by the conveyor belt for sorting are passed through the sorting slot Skibbles (1) sorted by size, first the small, the medium-sized, and last the large ones. The sorting conveyor belt transports the crabs past the sorting slot and the crabs fall through the sorting slot.

(2) Die Krabbenrichtrutsche muß von jeder einzelen Krabbe paßiert werden,durch schrägstellung der Richtrutsche auf 55 Grad Winkel wird die Krabbe durch das eigene schwergewicht in die richtige zufuhr lage gebracht und eine sicherre zufuhr garantiert.(2) The crab straightening chute must be passed by each individual crab By inclining the straightening slide at an angle of 55 degrees, the crab becomes brought into the right supply position by your own heavy weight and a safe one supply guaranteed.

(3) Die zu schälende Krabbe kommt von der Richtrutsche in den Ovalen führungkanal und wird von Druckluft angesaugt und durch den Führungkanal durch den Schäler geschossen Skitze(4) (4) Durch die Auffangtrommel wird das schälgut aufgefangen und zur Reinigung geführt Skitze (6) und (7)(3) The crab to be peeled comes from the straightening slide in the ovals guide channel and is sucked in by compressed air and through the guide channel through the Peeler shot Skitze (4) (4) The peeled material is caught by the collecting drum and guided for cleaning Skits (6) and (7)
