要がある。By the way, particularly hard rice such as exotic rice cannot be completely cooked by a series of the above-mentioned steaming treatments only once, and after the treatment process up to the third stage steaming section C, the first rice is again treated. A double steaming process is repeated from the first stage steaming unit A to repeat the steaming process. Also, such as packed food,
If it needs to be heat-processed again just before eating, it should be made into steamed rice that is pregelatinized and has an appropriate water content. Therefore, for raw rice that needs to be steamed with saturated steam for a long time, the block of the second stage steaming section B is made relatively long to increase the steaming time. Also, for those that require that the amount of free water adhering to the grain surface be suppressed to a certain degree or less, it is necessary to lengthen the block of the third-stage steaming section C to a relatively long time for treatment here.
