PROBLEM TO BE SOLVED: To provide a filter capable of suppressing the admixture of foreign matters to a fish-paste product and being readily maintained. SOLUTION: An opening part 12 is formed at the tip of a cylinder 11 and end walls 13 is made at the rear end. The outside of the side walls 13 is projected in a hemispherical state backward and plural slots 14 are formed in parallel on the end walls 13. When the tip of the cylinder is placed at the downstream side and the rear end is laid toward the upper stream side, a plastic raw material is passed through the slots 14, advanced into the cylinder 11 and sent out from the opening part 12 while being deformed. Since foreign matters incapable of passing through the slots 14 are prevented from advancing to the cylinder 11, a fish-paste product is not mixed with the foreign matters. Clogging hardly occurs. |
