I am trying to make alkaline water rice dumplings in large batches (about 50 kilos) I bought my glutinous rice grains directly from the producers and thus there are some rice grains mixed into the batch. Alkaline water rice dumplings are not supposed to have rice grains in them. Rice grains could not be cooked and merged together with the rest of the glutinous rice thus they will harden within the dumplings and the taste of the dumplings will be inconsistent.
Traditional methods of separating the rice grain from the glutinous rice grains require manual work in which you "eye" for the transparent grain (rice grain) from a small batch of rice pile and pick it out one grain at a time. This requires a lot of effort and time and is prone to human error. A single rice grain in the dumpling can cause deteriorate the eating experience tremendously.
How can I speed up the process of separating the rice grain and increase the accuracy of the system at the same time without relying on complex industrial machines or robots?
I tried to do research on it and even sought out ChatGPT and it was suggested to use the density separation method. Which places the rice grains in a liquid that relies on the density difference between the glutinous rice grain and the rice grain due to the difference in the amylase contents?
Will this method work? if it works, how do I measure the different densities between rice grain and glutinous rice grain? how do I make the liquid that can cause either rice grain to float as a form of separation?
