Embodiment 1

[0069]

[0070] Japonica rice with a water content of 15% to 16% (w.b.%) is used as raw material. Then, the non-japonica rice is put into the raw material tank 2 of the pretreatment unit 5, and the non-japonica rice supplied from the raw material tank 2 is spread on the endless belt conveyor 3 in a sheet form with a thickness of about 5 mm to 20 mm for conveyance. In the heating device 4 , hot air at 40° C. is supplied for 10 to 40 minutes to dry the japonica rice until the moisture content of the japonica rice reaches about 11% to 13% (w.b.%). Thereby, generate many tortoise-like or fish-scale fine fissures ( Figure 2 ~ Figure 4 ).

[0071]

[0072] The rice grains with fine cracks formed on the surface are carried out from the heating device 4 and supplied to the water filling drum 6 of the water filling unit 12 . The water adding part 12 controls the water adding amount through the valve 10 . Control the amount of water added so that the water content of the entire ...

Abstract

The present invention eliminates the need for power used for roll milling by significantly reducing the hardness of rice, and provides fine rice powder with good quality even when the rice is ground only with a jet mill. The present invention includes: a preprocessing step (5) of creating a number of fine cracks on the surface of an uncooked rice grain; a water-adding step (12) of increasing the water content of the rice grain having the fine cracks formed on the surface thereof; and a grinding step (19) of grinding, with a jet mill, the rice grain having absorbed water. That is, when water is added after the fine cracks are formed on the surface of the rice grain, the swelling of a compound starch grain proceeds remarkably faster than in the case of water being absorbed gradually through a germ. The rapid swelling increases the amount of strain in the structure of a cell wall, making it easy to break the strong structure of the cell wall and significantly reducing the hardness of the rice. At the time of grinding, due to the significant reduction in the hardness of the rice, the structure of the cell wall is easily broken and even a starch grain is finely ground.

Description

technical field [0001] The present invention relates to a method for producing rice flour capable of significantly reducing the hardness of rice even when rice is ground using only a jet mill, and rice flour obtained by the method. And provide fine and high-quality rice noodles. Background technique [0002] Rice flour is obtained by crushing rice. In response to the expansion of domestic rice (locally produced rice) consumption in various parts of Japan, new markets for rice have been opened up in the field of bread manufacturing and Western confectionary manufacturing. For example, manufacturing Bread using 100% of the rice flour, cakes using the rice flour, etc. are expected to be the cornerstone of market expansion. [0003] As a conventional method for producing rice flour, the following method has been known for a long time: washing polished rice with water, subjecting the washed polished rice to immersion treatment for 2 hours or more and within 24 hours to contain w...
