He discovered that rubbing the rice between his fingers while applying pressure removed the pestle. He returned to his workshop and immediately began working on a machine that he finished the next day, thus creating the first rice peeler horizontal cylinder. The invention was named the Engelberg Huller and was soon adapted to also work with coffee.

Rice husk ash has long been used in ceramic glazes in rice growing regions in the Far East, e.g. China and Japan. [2] Being about 95% silica, it is an easy way of introducing the necessary silica into the glaze, and the small particle size helps with an early melt of the glaze.
Rice-hull bagwall construction is a system of building, [1] with results aesthetically similar to the use of earthbag or cob construction. [2] Woven polypropylene bags (or tubes) are tightly filled with raw rice-hulls , and these are stacked up, layer upon layer, with strands of four-pronged barbed wire between.
For white rice, the whole rice is collected from the sheller and moved on to the whitener. Here, the film coat on the rice, which is called bran is removed from the rice and the bran is collected separately. The whitening process is done by a whitener. The whitened rice is polished by a silky rice_polisher. The polished rice is destoned again ...
