Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a steaming rice cooker for cooking sekihan by steaming mixed grains of glutinous rice and red beans (prior art). A common method is to put a mixture of grains in a pot and cook rice.

(Problem to be solved by the invention) However, in such a configuration, work events are low;
Furthermore, since the red beans themselves were colored, the coloring of the grains may be uneven, resulting in a decrease in commercial value.

(Means for Solving the Problems) Therefore, the present invention aims to provide a steaming rice cooker that can improve the commercial value, and has taken the following technical measures.

That is, a dipping device 1 for storing high-temperature water capable of absorbing mixed grains of glutinous rice and red beans, a coloring device 2 capable of coloring the absorbed mixed gold grains, and a coloring device 7L2 for conveying the colored mixed grains. Steam cooking f' which is equipped with a conveyance device 3 and a steam supply device 4 capable of supplying high-temperature steam during the conveyance in the conveyance device 3! i device configuration.

(Function) The mixed grains of glutinous rice and red beans absorb high-temperature water stored in the dipping device 1, are colored by the coloring device 2, and are conveyed in a predetermined direction by the 1112 feeding device 3. Then, this grain is (finally) bathed in high-temperature steam supplied from the steam supply device 4 to be cooked.

(Effects) Since the grains are colored after water absorption, the grains are colored well, and since the coloring is performed during the rice cooking process, automation can be achieved. Therefore 1
It is possible to make rice with high workability, less uneven color, and high commercial value.

(Example) An embodiment of the present invention will be described with reference to the drawings.

The base rice cooking device 5 has a primary steaming device 7 on the top of the frame 6,
Conveyor8. A dipping device 1, a secondary thinning device 9, etc. are provided, and a motor 1, which is the power source of the drive unit, is installed at the bottom of the frame 6.
0. Water heater which is a source of high temperature water11. Steam regulator 12 with a pressure regulator capable of cleaning high-temperature steam
etc.

The next steamer 217 is a tank 1 that stores mixed grains of glutinous rice and adzuki beans that have been soaked in advance and sent by an appropriate means.
3, and a steam supply device 14 capable of supplying high temperature moist steam to the stored grains. The secondary steaming device 7 may be configured to perform primary steaming by showering the grains fed on a net-type conveyor with high-temperature moist steam.

The conveyor 8 is provided in the rotating portion to convey grains to the soaking device 1 side after passing through the secondary steaming device 27. The soaking device 1 includes a water tank 15 that stores high-temperature water, and a grain conveying device 1 that is variable-speed capable of conveying the grains fed into the water tank 15 to the secondary steaming device 9 side.
6, and a heat insulating tank (not shown) provided on the lateral side of the ifI water storage tank 15. The heat retaining tank and the water tank 15 communicate with each other through a water hole (not shown) that is large enough to prevent grains from passing through. Therefore, when the high temperature water stored in the water tank 15 becomes low, the high temperature water in the heat retention tank is supplied to the water tank 15 through the water passage hole, and the water in the heat retention tank is reduced to a predetermined level. When the amount reaches a predetermined amount, water is supplied from the water heater 11 via an appropriate supply means until a predetermined amount is reached. Note that this control is performed by a computer (not shown), a sensor (not shown), and a control tool (not shown).

The secondary steaming device 9 is connected to a net conveyor-type conveyor device 3 which is rotatably provided to carry the grains conveyed by the grain conveyor device 16 in a predetermined direction, and a ventilation hole of this conveyor device 2i3. It is equipped with a grain supply device 4 capable of supplying wet steam from the grains to be transported. The steam supply device 4 is configured to be supplied with steam from the steam regulator 12 via appropriate means.

The coloring device 2 is provided above the transport start end of the transport device 713, and includes a plurality of small-diameter supply ports (nozzles) 17 in a direction transverse to the grain transport direction. The coloring device 2 is connected to a coloring liquid tank 18 containing a red coloring liquid via a liquid chamber tube 19, and a pump and a steam heater are connected to the coloring liquid tank 18 in the middle. 21, ``rL magnetic valve η, and float type flow meter n
and.

24 is a pressure gauge, and δ is a pressure adjustment valve.

Note that a liquid circulation circuit A is formed between the colored liquid tank 18 and the electromagnetic valve η. Reference numeral 26 denotes a drain valve that can drain the colored liquid remaining in the liquid chamber tube 19 on the coloring device 2 side.

Also, transport equipment? At a position above the conveyance surface of I3, stirring bodies n capable of stirring the grains colored by the coloring device 2 are arranged in parallel in the direction of conveyance of the grains.

Note that the agitator n is also configured as a speed change unit in a speed change device (for example, a continuously variable speed drive using a motor with an inverter, although not shown), and is provided with a lever that projects radially on the outer peripheral surface of the rotating shaft. ing.

(effect) Next, we will discuss the effect.

A predetermined amount of mixed grains of unhulled rice and red beans soaked in a separate soaking tank (not shown) is supplied into the tank 13 by an appropriate conveyance means. Incidentally, when the unhulled rice and the red beans are soaked separately and then supplied into the tank 13, they may be mixed together.

Next, when you open the shutter provided at the bottom end of the tank 13,
The grains fall onto the conveyor 8'' and are conveyed to the soaking device 1 side, and the amount of grains in the tank 13 decreases in relation to this, but since the grains are continuously fed by the conveying means, A predetermined amount of grain is always stored inside.

The grains fed into the water tank 15 are then transported to the secondary steaming device 9 side by the grain transport device 3716, and absorb high-temperature water stored in the water tank 15. The grains supplied from the soaking device 219 to the conveying surface of the conveying device 3 are conveyed by the conveying device 3 to the dipping device 9 in the opposite direction.

Further, when the electromagnetic valve η receives the drive command signal and opens, the colored liquid sent from the colored liquid tank 18 by the pump through the liquid indoor tube 19 heated by the air heater 21 is colored. , 712 are injected from the nozzles 17.

Therefore, the water-absorbed grains are bathed in the colored liquid sprayed from each nozzle 17, then stirred by the stirrer n, and then again bathed in the colored liquid sprayed from the subsequent nozzle 17 and stirred by the stirrer n. Ru. Further, while the conveying device 3 is conveying the colored grains, the grains are exposed to high temperature moisture supplied from the steam supply device 4 and sent through the conveying device 3, and are cooked to become red rice.

Therefore, since the rice can be forcibly colored in the rice cooking process, it is possible to automate the cooking of colored rice containing beans, for example, red rice.

Furthermore, since the coloring and stirring of the grains are repeated, uneven coloring is reduced and it is possible to produce cooked rice with high commercial value.

In this example, the pre-soaked grains were soaked in high-temperature water and then exposed to high-temperature steam.
Although it is configured to cook rice, rice can also be cooked by performing a primary steaming process in which high-temperature steam is applied before the water absorption process.

However, if high-temperature steam is supplied for a long time in this secondary steaming process, a large gelatinization phenomenon will occur on the surface of the grain during the water absorption process, causing it to become sticky, resulting in poor secondary steaming efficiency or a decline in quality. Sekihan may turn out to be fried.

Therefore, when cooking sekihan, it is better not to perform blow-off, or even if it is done, to lower the steam temperature or shorten the steaming time.

Further, by using the steaming rice cooking apparatus having the configuration of the embodiment, not only red rice but also ordinary white rice can be cooked, so that the suitability of rice cooking can be improved.

In addition, in the case of white rice, close the electromagnetic valve η or stop driving the pump to stop supplying the coloring liquid, and then supply high-temperature steam from the steam supply bag M14 and shower it on the grains. Just heat it up.

Next, when cooking red rice, the temperature of the high-temperature water stored in the water tank 15 is set lower than when cooking white rice, and the rotation speed of the stirring body H (the circumference of the tip) is set lower. (even speed is fine) is set high. If you do 4II like that, you can make red rice that is harder than regular white rice.

Furthermore, when cleaning the red rice after cooking, the coloring liquid remaining in the coloring device 2 and the liquid chamber tube 19 can be drained by opening the drain valve.
