DESCRIZIONE
Device for squashing of krill and other marine organisms comprising a soft protein containing material and a shell material, so that some particulate protein material and protein rich liquid are separated from a residue fraction comprising shell and further protein material. The device comprises a press band (1) and a sieve band (2) which are both endless bands with a certain elasticity and which in a defined region hereinafter called the squashing zone (3/8) are arranged closely adjacent to one another and arranged to move with a common velocity and in the same direction. The sieve band (2) being arranged to receive the material to be squashed upstream of the squashing zone (3/8) is perforated with a certain convenient mesh size. In the squashing zone (3/8) the sieve band (2) is supported by a plate (10) while press band (1) which does not have perforations, is supported from above by pressing rolls (9) arranged to exert a controlled pressure on the material resident between the two endless bands (1, 2) in the squashing zone against the supporting, perforated plate (10).
