(57) This invention is a food product selector that selects on the basis of the size of
the product, especially devised for selecting such products as frozen or fresh bivalve
molluscs, frozen food, etc., characterised by the fact that it is composed of a bed
(1) on which a series of shafts (2) are arranged lengthwise, all of which are jointly
motorised, each one of which is equipped with a series of rollers (3) that all have
a helicoidal hole, with the particularity that inside each shaft the size of the respective
rollers (3) become progressively larger from one end of the selector to the other,
in such a way that the rollers (3) with the smallest holes lie closest to the selector
loading zone so that the smallest products can drop through these smaller holes, whereas
the rest of the products are conveyed towards the rollers (3) whose hole size is slightly
larger, and so on and so forth, the biggest holes lying at the other end.
