A method for producing rice with a low glycemic index and a low glycemic load includes, in sequence, preparing husked brown rice, humidifying the rice with water at room temperature until reaching a moisture content equal to 18-22%, resting the rice for 24-60 minutes, heating the rice to a temperature of 80-85° C., cooling the rice in an environment at a temperature lower than the room temperature until the rice reaches a temperature of 10° C., reconstituting the rice for 24-72 hours, maintaining the moisture content, until the rice reaches the room temperature, heating the rice again until the rice externally reaches a temperature of 60-65° C., corresponding to an internal temperature greater than 70° C., cooling the rice to reach the room temperature, refining the rice having a moisture content equal to 18-22% and drying until reaching a moisture content equal to 12-13%.

The partial or full dehydration of organic or inorganic matter containing water by induction of matter into a vacuum and processing matter through a specially designed acceleration channel is disclosed. The inducted matter accelerates in air from zero speed to sub-sonic speed to reach supersonic speed. As the material transitions the sound barrier, it is subject to acoustic shock waves and an instant negative pressure drop occurs. The sound waves disintegrate, disinfect the material and extract part or all moisture from any organic or inorganic material.

An imitation corn kernel is used to emulate a real corn kernel for use in research and testing of a grain drying system. The imitation corn kernel includes a core material that retains moisture and a shell material that repels moisture.

A method of processing grain from a dryer includes maintaining a transition zone within a volume of received grain, the transition zone being a cross section of the volume of the received grain that is at a same temperature, by cooling and drying the received grain; and extracting cooled grain.

A method for producing freeze-dried rice according to the present disclosure includes a rice cooking process of obtaining cooked rice by cooking rice with superheated steam, and a freeze-drying process of obtaining freeze-dried rice by freezing the obtained cooked rice and then drying the frozen cooked rice under vacuum. Preferably, in the rice cooking process, the cooked rice is obtained such that a rice cooking increase rate (a ratio of a weight of rice after cooking to a weight of rice before cooking) falls within a range of 260% to 280%. More preferably, in the freeze-drying process, the obtained cooked rice is washed, and then the cooked rice is frozen and dried.
