Steamed rice cooling machine. Horeiki literally means “cold emitting machine”. Usually a stainless steel mesh conveyer that blows cooler air on the rice to bring down the temperature immediately after steaming. For even cooling, there is a roller with finger like prongs across the conveyer that will work to flatten the rice out to an fixed layer depth. There is a duct attached to the horeiki and the speed of airflow over the rice can be used to control how fast the rice is cooled. Rice can also be cooled manually, usually by spreading out on a fabric sheet over a bamboo mat on the floor, but the Horeki speeds up the process.
