A method for obtaining tomato seeds

Abstract

The invention relates to the technical field of tomato seed extraction, in particular to a method for tomato seed extraction, comprising the following steps: S1: pouring the tomatoes into a feed box together with fermentation liquid after cutting; S2: the materials in the feed box and the fermentation liquid enter the seed extraction gap along the feed pipe; S3: the materials in the seed extraction gap are transported from bottom to top during the rotation of the spiral plate, and the tomato seeds in the seed extraction gap are collected after passing through the filter holes on the inner cylinder together with the fermentation liquid under the action of centrifugal force, and the tomato residues in the seed extraction gap are removed from the upper port of the inner cylinder as the spiral plate rotates and are collected; S4: the tomato seeds are light-shielded and sealed for storage after being washed, sterilized and dried; the invention rotates the spiral plate on the inner side of the inner cylinder, so that the tomato materials in the inner groove of the inner cylinder are dispersed under the rotation of the spiral plate, and under the action of centrifugal force, the tomato seeds are exposed from the tomato materials and quickly pass through the filter holes on the inner cylinder, thereby greatly improving the seed extraction efficiency and effect of the tomato seeds.
