Abstract

PURPOSE:To prepare high-quality steamed rice with good fragrance efficiently, by providing a passageway with a hot steam jetting means and an exhaust means to discharge fatty acids released together with steam by the hot steam jetting means to the outside of the passageway. CONSTITUTION:In continuous preparation of steamed rice wherein the steamed rice 5 transported by the conveyor 3 is treated by desired steaming action in a passageway, the passageway is provided with both the hot steam jetting means 9 and the exhaust means 13 to discharge fatty acids released together with the steam by the means 9 to the outside of the passageway. Consequently, the fatty acids can be discharged smoothly, efficiently, and forcedly. Even in continuous preparation of steamed rice, high-quality steamed rice having good fragrance, capable of preventing change in color and acidification of product can be prepared in high productivity, and in high operation efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for producing steamed rice in a sake production process and the like.

Conventionally, this steamed rice manufacturing apparatus has a steamer B storing steamed rice A as shown in FIG. Using a steamer steamer method in which heated steam is applied using a heating coil to create a steaming effect, or using a wooden barrel E with a lid or sheet on the top as shown in Figure 2, the top of the drainboard F inside the wooden barrel H is used. Steam is injected from the steam jetting part G on the lower surface of the drainboard F to give the steamed rice A the required steaming effect, or steamed rice A is put into a vertically open cylinder H from above as shown in Fig. 3. In the lower part, steam is ejected from the steam injection port (■), and the rice is discharged from the lower opening and transferred from the conveyor J.Furthermore, the rice is continuously transferred by the conveyor and steamed by the steam injection while passing through the passage. There are continuous steamers for steaming rice, but in the steamer type steamer mentioned above, the fatty acids contained in the steamed rice are naturally released. It is unsuitable for rice production, and has the disadvantage of being inferior in potash production efficiency and work efficiency.In addition, the above-mentioned continuous steamer and soybean rice steamer have production efficiency and work efficiency comparable to that of steamer steamer. Although it is better compared to the above, it has the disadvantage that the finished product has a bad aroma because the fatty acids are steamed without losing it, and the quality is poor because it is easily oxidized and spoiled, resulting in color change or a vinegar taste after completion. The current situation is producing results.

The disadvantage is that the aroma after steaming is not good because of the steaming process.
Furthermore, even in conventional continuous rice steamers, fatty acids are accumulated during steaming in order to prevent steam from escaping, so the drawbacks mentioned in NiJ cannot be overcome.

The present invention is capable of continuously producing steamed rice with high production efficiency and working efficiency, and is also equipped with a functional means for releasing fatty acids in a regular manner during steaming, and is capable of producing high-quality steamed rice with good flavor. The purpose of the present invention is to provide a method for producing steamed rice and an apparatus therefor.

In FIG. 4, reference numeral 1 denotes a cover, and a net conveyor 3 is disposed in a passage 2 formed by the cover to convey steamed rice 5 that has been conveyed by another conveyor 4.

6 in the figure is the bottom surface of the bottom surface of the net conveyor 3.
8 is a live steam injection means for injecting live steam to the steamed rice 5 on the net conveyor 3 from the bottom surface of the net conveyor 3. At this stage, the steamed rice is first moistened and steamed while being transported. Reference numeral 9 denotes a heated steam injection means located next to the live steam injection means 5.6, which applies a forceful steam injection action from above to the steamed rice on the net conveyor 3 from above the passage. Steam injection device I
It consists of a combination of I and heating heater I2, and at this point, heated steam is sprayed onto the steamed rice in a higher temperature atmosphere than in the previous stage, and the fatty acids generated in the previous stage are also removed from the steamed rice at this stage. Exhausted steam injection device 1
1 and the heating mixture 12 are discharged to the outside of the passage 2 by an exhaust means 13 formed on the lower surface of the net conveyor 3 at a position corresponding to the setting location. Reference numeral 14 denotes a heated steam injection means located in a box 15 with an opening on the top surface located under the net conveyor 3 that performs finishing steaming on the steamed rice that has undergone the fatty acid removal process, and a steam injection device 16.
This method consists of a combination of heating and a steamer 17, in which fresh clean steam is injected onto the steamed rice, and moisture on the surface of the steamed rice is removed by the heating and steamer 17.

In the case of this actual sample, the steam injection device 11 and heating heater I2 were installed on the top surface of the net conveyor 3, but this is because the steam is injected from the bottom surface of the net conveyor 3 toward the top surface in the previous stage. Middle (7) Since MiliW exists on the net conveyor 3, its location was inevitably identified for its efficiency, but it was installed below the net conveyor 3, heated steam was injected, and the fatty acid was sent along with the steam to the top of the net conveyor. It is also possible to discharge the steam using a provided exhaust means, or the live steam injection means 6 can be connected to the net conveyor 3.
Of course, it is also possible to provide the heated steam injection means 9 on the upper surface of the net conveyor 3, and to provide the heated steam injection means 9 on the lower surface of the net conveyor 3, and to attach and form the heated steam injection means for finishing on the upper surface of the net conveyor 3.

However, according to the present invention, although the minimum 4'IP heat is used for steaming rice, a large amount of about 3° to 50% of the heat calories absorbed by steamed rice is steamed, and the surplus steam is used for fatty acids. Based on the basic idea of using it, there is a functional #1m in the middle of the aisle.
By installing the H1 method, we were able to extract fatty acids smoothly and efficiently, so even in continuous steamed rice production, we were able to achieve a solution that prevents the product from changing in color or becoming vinegary with a good aroma. It is something that
