Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] In the present invention, in the process of fried rice grains from the bottom to a high place, water is added to the rice grains without any unevenness, the taste is improved, and the rice is supplied from the bottom. The present invention relates to a rice grain humidifier that discharges rice grains from high places.

[Conventional technology and its problems]

It is generally said that the important factor for the taste of cooked rice is the moisture content of white rice. White rice containing about 15% water does not crack or split even when immersed in water, so it is cooked into a perfect rice grain, and the viscosity and hardness that are factors of taste are kept moderate and the taste is good. Is. However, the water content is 14%
The cracked white rice has a water absorption rate that is too fast when soaking and momentarily causes cracks in the rice grains, and soon a through crack occurs in the inside of the rice grains. Since it is broken, it is a low quality cooked rice that is neither chewy nor sticky. In short, in order to improve the taste, it is necessary to humidify the rice grain to a moisture content of about 15%, which is the inspection standard of the government.

Conventionally, as this type of rice grain humidifying device, a tank is equipped with a fried machine to form a circulation path, and a water addition device is provided in a part of this circulation path to add water while circulating rice grains. Are known. In this product, since the water content of rice grains is intermittently added, water spots are unavoidable, and the rice grains are discharged from the grain lifting machine and tank for loading the rice grains into the tank and transported to the next process. It is necessary to install a grain machine and position the bottom of the tank to a certain height.

On the other hand, as a continuous rice grain (polished rice) humidifying device, for example, there is JP-A-56-26164 of the present applicant. This product does not wet the surface of the rice grain without causing it to wet and cause cracks in the rice grain at the maximum limit of the natural water absorption rate of the rice grain. However, this product could not add water at a rate higher than the natural water absorption rate, and the tank was required to have a certain height because of grain removal from the bottom as in the above.

Further, in Japanese Patent Application Laid-Open No. 61-174949, there is proposed that the tank is hermetically sealed and the pressure is increased by a pressure device. Although this may increase the water addition rate, the problem of relatively high tank position remains.
