Routine manual cutting and cleaning methods for eggplant seeds are laborious and labor intensive. Especially in the case of a large amount of eggplant, when the weather is not stable, it is not conducive to grab the sun. One advantage of the new method of threshing with a washing machine is that the processing personnel no longer use the fingers to dig the seeds directly, which greatly reduces the labor intensity and saves labor and time, which is 8 to 10 times that of the manual method. This method does not affect the normal germination traits of seeds, does not waste seeds, and has a high recovery rate. The second is that the seed surface is clean, the color is positive, the glossiness is obviously improved, and the appearance of the product is excellent. The washing procedure is as follows: Electromechanical preparation. A normal functioning washing machine, power board and rinse water. Add water to about 70% of the highest water level in the tank. Select fruit slices. Choose the complete seed with no pests and post-ripenings and slice it laterally on a wooden mat, about 1.8 cm thick. Cut the seedless little end without cutting. The slicing preparation should be used with the cut, and the cut should be used up to avoid discoloration. Power off. Turn on the power and turn on the machine. After tumbling with strong washing water, you can add fruit and vegetable slices without soil contamination. Adding 10 kg to 13 kg is appropriate. Note that the height of the water layer in the tank does not exceed the maximum water level, and the threshing time is 15 minutes. ~ 20 minutes, observe the vast majority of slices broken, separated seeds and pulp, you can shut down. Seed rinse. Put the inner pulp mixture into the basin, add water, dilute and stir. After the seeds are settled for a while, remove the above pieces of seedless pulp with bamboo and pour the suspended water slowly to leave the seeds. Rinsing with water is repeated until the seeds are cleaned without any impurities. Then, the washed wet seeds are placed in a cloth bag and the excess water is spun off. The air is dried in a clean colorless cloth or on a clean fine grass mat in time, and the water content of the seeds is up to standard dryness. .
