Description

[Detailed description of the invention] (Industrial application field) TECHNICAL FIELD The present invention relates to a rice steaming device for grains.

(Prior Art) As a rice cooking means, a structure has been considered in which grains are exposed to high-temperature steam, immersed in high-temperature water, and then exposed to high-temperature steam again to cook rice.

(Problems to be Solved by the Invention) However, since grains vary in variety and freshness, it is not possible to obtain high-quality cooked rice with the rice cooking device having the above configuration.

(Means for Solving the Problems) Therefore, the present invention aims to improve the adaptability of cooking grains, and has taken the following technical measures.

That is, in a steaming and rice cooking apparatus that immerses grains supplied with high-temperature steam in the primary steamer 1 in high-temperature water and then supplies the high-temperature steam again to cook the rice, the primary steamer 1 is provided with a steam amount adjusting means. It has the structure of a rice steaming device for grains.

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

The grain steaming/cooking device 2 includes a primary steaming device 1, a conveyor 4, a dipping device 5, a secondary steaming device 6, etc. in the upper part of the frame 3, and a motor which is the power source of the drive part in the lower part of the frame 3. 7. Equipped with a hot water regulator 8, which is a source of high-temperature water, a steam regulator 9, which can purify high-temperature steam sent from the boiler, and has a pressure regulator (not shown), etc. There is.

The primary steaming device 1 is provided with a receiving port 10 that can receive pre-soaked grains at the upper end, and has a switching operation (manual or automatic) for discharging and stopping the grain at the lower end. A grain tank 12 equipped with a shutter 11 that can be used for drying, and a plurality of steam pipes 1 disposed at a predetermined interval in the vertical direction in the middle of the grain tank l.
3.14. The steam pipes 13, 14 are each equipped with a plurality of steam exhaust ports 15, and are also provided with a regulator 16 that can adjust the amount of steam supplied (and can also stop the supply). . Also, a steam pipe 13.
The steam temperature of the steam sent to No. 14 is approximately 100% at constant pressure.
℃, and the temperature can also be controlled via a temperature control means (not shown).

FIG. 3 shows that the steam guide pipe 17 communicating with each steam pipe 13, 14 is provided with an adjustment device 16.
The amount of steam in the steam pipe 13 located on the upper side can be adjusted (or stopped) by this operation. In addition, in both embodiments, a base adjustment device (not shown) that can be sent to the steam guide pipe 17 is provided.

The soaking device 5 includes a soaking tank 18 that can store high-temperature water of about 85° C., and a conveying device 19 that can transport the grains sent into the soaking tank 18.

The secondary steaming device 6 is transferred to the dipping tank 18 by the conveying device 19.
An endless belt on which grains transported outside can be loaded and transported, and a space formed between the grain transport side and the non-transport side of the primary steamer 1, and A plurality of steam chambers 21 are provided in the direction of movement of the belt.

The endless belt is provided with a large number of ventilation holes that prevent grains from falling through it, and is rotatable. Further, the steam chamber 21 is formed into a box shape with an open top surface, and is provided with approximately the same width as the width in the transverse direction with respect to the grain conveyance direction. The upper surface of each steam chamber 21 is brought close to or in contact with the lower surface of the grain conveying side part of the endless belt, and about 100 meters are placed inside the chamber toward the bottom wall.
A steam pipe η comprising a plurality of discharge nozzles capable of discharging steam at a temperature of ℃ to 115℃ at predetermined intervals in the width direction.
has been established. Note that the temperature of the steam sent into the steam pipe η via the steam guide pipe can be adjusted via a temperature control means. Further, in this embodiment, the amount of steam formed into the steam-cooking device z is configured to be substantially constant, but it may be configured to be adjustable by a steam amount adjusting means. 23 is a cover.

Reference numeral 24 denotes a layer thickness is device provided on the grain tank hill, which is capable of adjusting the layer thickness of grains which are subjected to primary steaming in the primary steaming device 1 and transported by the conveyor 4.

(Operation) Next, the operation will be explained. First, soaked grains are fed into the grain tank ρ in advance. and,
The base regulator is operated to send steam into the steam guide pipe 17 as desired, and the regulator 16 is operated to supply high-temperature steam to the grains from the steam pipes 13, 14 for a predetermined period of time. Then, when a preset time is reached, the operator operates the shutter 11 to cause the steamed grains to fall onto the conveyor 4.

Then, this grain is conveyed by the conveyor 4 and fed into the soaking tank 18. Then, the grains are stored in the soaking tank 18 to absorb high-temperature water, and are transported to the secondary steaming device 6 side by the transport device 19, and are supplied endlessly from the end of the transport. The grains that have been exposed to high-temperature steam and immersed in the primary steamer 1 are further conveyed by this endless belt, but at this conveyance speed, the grains reach the steam chamber 2! The rice is cooked by bathing in high-temperature steam supplied through an endless belt. Incidentally, the grains that are sent following the grains that have fallen due to the "open" operation of the shutter 11 gradually fall following the falling grains.

Therefore, when the grains are sent down, they are also exposed to high temperature steam supplied from the steam pipes 13 and 14.
Thereafter, primary steaming of grains can be carried out continuously.

Next, when reducing the base air amount depending on the grain conditions, one of the regulators 16 is operated to reduce or stop the supply of steam supplied from one steam pipe n. Note that it is also possible to increase or decrease the amount of steam by operating both adjusting tools 16.

Therefore, since it is possible to supply the amount of steam according to the conditions of the grain, it is possible to prevent quality deterioration due to, for example, insufficient steaming, and it is possible to obtain cooked rice with high commercial value.

(Effects) Since the amount of steam supplied can be adjusted, rice can be cooked by supplying the amount of steam that matches the conditions of the grain, and it is possible to obtain cooked rice of good quality.
