ABSTRACT:
A processing section in a gel coat processing unit for seeds to uniform the coating amount of seeds with gelatinizer to change a grain diameter of coated seeds without taking plenty of time and labor nor cost. In the processing section the seed is introduced from an outside into a passageway filled with gelatinizer which becomes the polymeric gel by hardening and a coated seed made by coating the seed with the gelatinizer is dropped from the passageway, the processing section comprises: a gel storing section to which the gelatinizer is supplied from an outside, the gel storing section communicating with the passageway; an opening-closing valve for opening and closing an aperture between the passageway and the gel storing section; and an extension-contraction member for extending and contracting an internal space of the gel storing section, the extension-contraction member moving in the gel storing section linked with an opening and closing of the opening-closing valve, the extension-contraction member being movable between a first position where an internal space of the gel storing section has the minimum capacity corresponding to a position when the opening-closing valve is opened and a second position where the internal space of the gel storing section has the maximum capacity which is equal to the minimum capacity plus an amount of the gelatinizer used for the coated seed corresponding to a position when the opening-closing valve is closed.
