Definitions

  • the present invention relates to a device for separating mussel clusters, comprising brushes which upon relative movement between brushes and mussel clusters influence the mussel clusters.
  • O FI device and a method for cutting connected mussels from each other, the device comprising a plurality of plates along which the mussels are transported and which is provided with a plurality of openings through which one or more hook-shaped means are moving for tearing off the mussel threads binding the clusters together.
  • the task underlying the present invention is to give instruction for a device which in a gentle and effective manner can loosen mussels which are grown together in clusters without subjecting the mussels to so strong mechanical influences that the mussels are crushed, even though the mussel clusters have been grown on ropes or lines freely suspended in a ram stream and therefore having thinner shells than bottom grown mussels.
  • a device of the type stated in the preamble which according to the invention is characterized in that it further comprises a perforated support which the mussels in the mussel clusters by means of one or more first brushes on the one side of the support are partly pressed down against and partly pressed through for cutting the clusters due to relative movement between clusters and support.
  • a set of scraping brushes tearing away and removing the mussels which are tangled in the mussel threads, and keeping that said side of the support clean.
  • the first set of brushes influences the mussel clusters with a resilient force, said brushes aiding in cleansing the mussels for growths before the latter are passed on in the refining process.
  • the size of the perforations is adapted to the average mussel size and can constitute 120-130% thereof, the per ⁇ forations being diamond-shaped, round or out-of-round.

  • the device can also comprise a plurality of supports having co-operating relatively moving first set of brushes and possibly scraping brushes, the support being arranged such that the mussels being treated are successively transported from one support to the other.

Abstract

Un dispositif de séparation de groupes de moules comprend des brosses mobiles (3a-3d) qui coopèrent avec un support perforé (2) portant ou déplaçant des groupes de moules (1). Le dispositif comprend un premier ensemble de brosses (3a-3d) qui presse ou comprime de manière résiliente les groupes de moules (1) partiellement vers le bas contre le support (2) et en partie au travers de celui-ci, pour couper les groupes ou bouquets de moules au moyen des bords (2b) des perforations (2a). De l'autre côté du support perforé (2), des brosses râcleuses (4a-4b) peuvent être prévus pour détacher et enlever les moules (1b) qui tiennent par les fils des moules, et pour garder le support (2) propre. La dimension des perforations est adaptée à la dimension moyenne des moules et les bords (2b) des perforations sont pourvus de sections à bord tranchant et/ou de sections dentées qui effectuent le cisaillement et l'enlèvement des byssus qui tiennent les moules groupés, enchevêtrés et fixés au milieu environnant. Eventuellement, plusieurs supports successifs peuvent être prévus pour traiter et nettoyer les moules et effectuer en même temps leur triage selon la taille. Le dispositif effectue un traitement plus doux des moules spécialement cultivées qui possèdent des coquilles plus fines que les coquilles qui se développent en profondeur.
