- the air volume at this time is, for example, 6 m 3 / ton'h or less.
- the grain after the refining is discharged from the tempering tank 20 through the discharge gutter 25 by the discharge valve 24.
- the grain refined in the tempering tank 20 is supplied to a supply hopper 39 of a grain grinder 34 by a conveying means 41, and is subjected to milling. That is, the embodiment shown in FIG. 3 is a method of directly milling high-moisture (20-30% moisture) grains after the refining (see step 6 in FIG. 1), but is not limited thereto.
- a commercially available grain dryer may be provided in the process preceding the grain mill 34.
- the refined high-moisture grains are sent to a refining room 37 of a grain refining machine 34 and subjected to a grinding action by a refining trochanter 35.
- the outlet of the refining chamber 37 is pressed by the external resistor 38, the inside of the refining chamber 37 is in a moderately high pressure state, and the bran layer and the germ are peeled off to perform the polishing.
- the GABA content and the magnesium content in the endosperm at a milled rice yield of 90% are remarkably increased as compared with ordinary milled rice.
- hypochlorite ion solution may be used.
- water was sprayed to adhere to the surface of brown rice as atomized water droplets, and the diameter of the atomized water droplets was set to 0.1 mm or less.
- the water was transferred to a tank and tempered for 210 hours.
- the optimal ambient temperature during this tempering was 16-24 ° C, and the tank was ventilated by taking in outside air.
- the water temperature was the temperature of tap water, and no pH adjustment was required. A series of operations were performed at room temperature of about 20 ° C.
- the brown rice or paddy was dried by a usual drying method to a moisture suitable for hulling and milling, and then hulling was milled.
- the GABA content in the endosperm at a yield of 90% is increased by about 20 times that of ordinary milled rice (see Fig. 5). It can be seen that the magnesium content of the endosperm is about three times that of ordinary milled rice (see Figure 6).
- water was sprayed and adhered to the surface of brown rice as atomized water droplets, and the diameter of the atomized water droplets was set to 0.1 mm or less. After completion of the water addition, they were transferred to a tank or the like and tempered for 2-3 hours. The optimal environmental temperature during this tempering was 16-24 ° C, and ventilation was performed by taking in outside air into the tank. The water temperature was the same as tap water, and no pH adjustment was required. A series of operations were performed at a room temperature of about 20 ° C. After the tempering, the brown rice or paddy was superheated at 130 ° C for 3 minutes, dried by a normal drying method to a moisture suitable for rice polishing, and then ground rice *.
- the milled rice thus obtained was 4.3 times at a yield of 90%, 4.4 times at the embryo, and 1.2 times at the bran layer.
- GABA content in endosperm is increased (see Table 1).
- the conventional production method is 79% compared to the conventional production method in which the brown rice is immersed in water and enriched by this method.
- the manufacturing method was 10%. Therefore, by using the present method, brown rice that retains the shape of rice during cooking and has little starch elution and is excellent both visually and taste can be obtained.
- the wheat flour obtained in this manner had a GABA content increased by about 3.8 times or more as compared with commercial F wheat flour (see Fig. 7).
- the corn kernels thus obtained had a GABA content approximately 1.9-2.3 times higher than that of the corn kernels continuously immersed (see Fig. 8).
