Accelerated machine the process of soaking and germinating seeds

Abstract

Germinated seed production is a processing of high value seeds but takes many days to produce because many steps require meticulousness, especially soaking and germination process, which is an important step that affects the amount of GABA and the overall quality. This project is to fabricate a machine to speed up the process of soaking and germinating the seeds. Using the principle of water flowing through the seeds by spraying water, adding moisture to the seeds together with the spray off that is allow the seeds to germinate the roots. Studying factors affecting seed germination include 3 spraying periods (20, 40 and 60 min) and 3 take a rest period (20, 60 and 100 min) by controlling the flow rate at 2.64 L/min/kg of paddy. Jasmine 105 paddy rice was used as a sample. The results showed that the water spray duration of 20 min and the take a rest time of 60 min is the shortest condition that causes the paddy to germinate within 24 h and the root length is approximately 1 mm after 36 h, which helps to reduce the soaking and germinating time by 2 times compare with the traditional process about 2-3 days without adding substances, accelerating the water condition, reduce water and times consumption with the traditional process about 5 times and 3 time, respectively. in addition, the rice quality detected the amount of GABA increasingly.
