On the other hand, the content of the present invention will be described in more detail by examples. However, these examples are only presented to more easily understand the contents of the present invention, the scope of the present invention is not limited by these examples.

Device production

Steam processing unit for supplying the raw material in the brown state to eject the steam to the raw material, waste steam removal unit installed in the steam processing unit to discharge the waste steam generated in the steam processing unit to the outside, steam through the steam processing unit A device including a pre-processing unit which receives a processed raw material and removes the rice bran layer remaining on the surface of the raw material and processes it into rice, and a controller which controls the operation of the steam processing unit and the waste steam removing unit is manufactured.

Materials and Experiment Methods

The material used in this experiment was purchased from Hwaseong, Gyeonggi-do, processed into brown rice and white rice, and used as test material.

The steam treatment test was carried out at 5 ° C intervals up to a steam temperature of 60 to 85 ° C, and the treatment time was 4 levels at 10 second intervals up to 10 to 40 seconds. In addition, the temperature change investigation was measured by using a temperature measuring sensor (PT100Ω) at the raw material inlet, the steam treatment unit, the waste steam removal unit, and the metropolitan government where the temperature change occurs. After the measurement was repeated three times using a single grain moisture meter (PQ-510). In addition, the rice exterior quality survey was visually inspected by the rice exterior quality survey method, and the samples collected according to treatment conditions were calculated by weight ratio.

Water content change during steam treatment

After the steam treatment unit was sealed (before improvement) so that steam was not ejected to the outside, the moisture content change of grains when steam treatment was shown in Fig. 5, in the case of brown rice, in the first stage steam treatment unit, the water content was 0.7 to 0.8. % Increase, 1.7-1.8% increase in the two-stage steam treatment section, 3.2-3.5% increase in the drying section (dehumidification section), and white rice showed similar trends. Therefore, after removing the drying treatment unit that has a large increase in moisture content, install and improve the blower to forcibly discharge the waste steam to the outside of the steam treatment unit, and change the water content when it is connected to a blower-type rice polisher to prevent the increase in water content. As shown in FIG. 6, the water content was slightly increased to 0.1 to 0.5% as compared with the untreated rice as the final product.

Change of grain temperature by process during steam treatment

As a result of examining the change in grain temperature of each process when steaming and browning the brown rice at the same time, the grain temperature was 18.8∼19.0 ℃ during raw material injection as shown in FIG. As the grain temperature increased, the grain temperature was 64.3 ~ 79.3 ℃ when the steam treatment temperature was 65 ~ 80 ℃.

In addition, after steam treatment, the waste steam was forced out into the blower, and when the instant cooling was performed, the grain temperature of the steam exhaust portion dropped to 28.3 to 30.9 ° C. Subsequently, when the white rice discharged from the steam treatment unit was directly whitened by a blow mill, the grain temperature of the white rice was slightly increased from the grain temperature of the steam treatment discharge unit to 32.0-32.5 ° C., but management was possible at a relatively low grain temperature.

White rice after steaming during steam treatment

When steaming and steaming brown rice at the same time, as shown in Fig. 8, the complete grain ratio tends to decrease slowly as the temperature increases from 65 ° C to 75 ° C as shown in FIG. On the other hand, the decrease was sharply increased to 80% at 80 ℃. In addition, the yield rate increased slowly to 75 ° C, inversely proportional to the decrease of the total grain rate, and increased to 80 ° C.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include examples of many such variations.
