Description

[Detailed Description of the Invention] This invention relates to an improvement of an automatic rice washing and draining device in a continuous automatic rice cooking device which is capable of cooking a large amount of rice within a required time.

To explain the outline, a large amount of unwashed rice is continuously and automatically sent from a rice storage silo to an ice supply silo for unwashed rice, and a measuring device installed in this ice supply silo quantitatively measures the amount of unwashed rice. Rice is automatically supplied to multiple water pressure washer machines installed on a turntable at their set positions to wash the rice, and the rice washing and finishing switching valves of the water pressure washer machines are controlled by horizontal rotation of the water pressure rice washer machine using the turntable. A related cam mechanism is used to switch to the finished side, and this fixed amount of washed rice is allowed to fall naturally into an automatic drainer installed below it, and is then washed by injecting finishing washing water and processed by the draining action of the automatic drainer. death,
This fixed amount of washed rice is filled by gravity into a rice cooking container, such as a rice cooker, which is set in advance under an automatic drainer, and a fixed amount of water is poured into the rice cooking container by a fixed amount water injection device.

Then, an aerial cable system (ropeway system using gondolas and ropes) is installed in front of the rice cooking container containing the fixed amount washing rice and fixed amount water injection using a driving roller conveyor.
The rice is sent to a conveyor, and the conveyor slowly moves to complete the absorption of a fixed amount of water into the rice.The rice cooker uses the exhaust heat of a continuous rice cooker (a tunnel-type rice cooker that cooks rice using the heat of the combustion flame of a gas burner) installed directly below the rice cooker. The rice is transferred to the continuous rice cooking device while being preheated, heated and boiled while being slowed down, and subjected to uneven treatment until the rice is cooked.The rice cooking container is sent to the next conveyor, the roller conveyor, and then this rice cooking container is transferred to the reversing machine. Then, by automatic operation of this inverting machine, the rice cooking container is raised and inverted at the top, and the cooked rice inside is automatically dropped onto a serving machine equipped with a loosening device, and the rice is weighed by a weighing machine and transferred to another rice container. This is transferred by a roller conveyor and delivered.

This invention will be explained in detail below with reference to the illustrated embodiment.Unwashed water is sent to the ice supply silo 3 for unwashed rice through the rice feeding pipe B by the pneumatic rice feeding device in the ice storage section, as shown in FIG. The unwashed rice enters the cyclone 8 at the top of the supply silo 3 and is separated from the air, and the rice is stored in the supply silo 3.

Level control motor 9 installed in this supply silo 3
The rotation is stopped by the unwashed rice that has been sent.

From this point on, a timer set electrically starts to operate, and rice feeding is completed under time control.

At the same time, when the unwashed rice is consumed in the lower part of the supply silo 3 and the amount of stored rice decreases, the level control motor 9 starts rotating and rice feeding is started, so that this movement is repeated in a whitening manner.

For example, a plurality of quantitative rice measuring devices 4 as Masu 2 measuring devices are installed side by side on the turntable 10 (set at a predetermined interval).
When one of the rotary water pressure rice washers 5 reaches its set position, the electric circuit of the electric cylinder 11 is closed by a switch such as a limit switch, and the electric cylinder 11 is turned off.
One reciprocating operation is started via .

The quantitative rice measuring device 4 pushes the unwashed rice to a fixed amount using the ram 12 of the electric cylinder 11 and the forward/backward pusher 13 and conveys it to the drop-off hopper 14 section.

The measurement of this unwashed rice can be changed and adjusted by the adjustment knob 15.

A fixed amount of unwashed rice weighed by the measuring device 4 is automatically supplied from the drop-off hopper 14 to a water pressure rice washer 5 located directly below it, and the rice is washed in this water pressure rice washer 5.

This water pressure rice washer 5 utilizes water pressure pressurized by a water pump 17 from a rice washing tank 16 installed below, and uses a rotary joint type water divider 18 to send water to each water pressure rice washer 5 through water pipes 19 and 20. It looks like this.

The water overflowed in this water pressure washer 5 is
The rice washing tank 16 is passed through the overflow pipe 21 again.
It is returned to the public for reuse.

The water pressure washing action of this water pressure washing machine 5 is as follows.
Washed rice is raised by pressure water from water supply pipes 19 and 20 in the rice washing pipe 24, which is a rice raising water circulation pipe installed almost vertically in the center of the rice bowl, and the rice washing circulation is carried out by the automatic switching valve 22 installed in the upper part of the rice shade. It descends again into the water pressure rice washer 5 from the mouth and ascends again through the rice washing pipe 24, performing a circulating flow rice washing action.

Then, the fixed amount of washed rice that has been washed is force-fed from the finished port to the finished pipe 26 by the switching action of the automatic switching valve 22.

The rice washing and finishing operations are performed by opening and closing the automatic switching valve 22 shown in FIG. is actuated by the guide cam rail 27, thereby automatically repeating the motion of rice washing → finished rice, water supply → rice washing, finished rice.

Thus, a small amount of washed rice that is automatically discharged together with water from the output tube 26 of the water pressure rice washer 5 is placed in each washed rice draining chamber SW between several rotary blades 31 in the draining case 49 of the automatic draining device 6. The washed rice is divided into portions and automatically flows in one after another, and while being pushed by the several rotary blades 31, the rice is dehydrated and uniformly drained through the draining hole 47 of the draining case 49 as shown by the arrow in FIG. The rice is cleaned and washed. At this time, cleaning of the washed rice can also be promoted by flowing clean water from the finishing water shower 32 into the washed rice.

Then, the cleaned and washed rice that has been drained automatically falls into a rice cooking container 34 such as a rice cooking can placed on the drive roller D at the lower side, and is filled in a fixed quantity.

In this case, if the rice cooking container 34 is not located below the automatic drainer 6, the automatic drainer 6 and rice washing turntable 10 will be automatically stopped by the automatic control device after a certain period of time (5 to 10 seconds). It looks like this.

This is a safety mechanism to prevent mistakes.

A water injection pipe 35 connected to the system tank 36 of the quantitative water injection device 7 at the same time as fixed amount filling of washed rice into the rice cooking container 34.
A certain amount of water suitable for cooking rice is poured into the rice cooking container 34.

This quantitative water injection device 7 uses a high tank system and a liquid level control system in combination to ensure a constant water pressure, and uses a highly accurate timer to open and close the solenoid valve 37 for quantitative water injection.

Also, the amount of water injected is adjusted using the timer dial.

When water is poured into the rice cooking container 34 at a constant rate, any change in water temperature will affect the cooking time, so hot water and water are mixed together in order to maintain a constant water temperature even in summer and winter.

The turntable 10 and the rotary feed blades 31 of the automatic drainer 6 are rotated at low speed by a motor 38 rotating a rotating shaft 39.degree. 40 via a sprocket and a roller chain.

After filling a fixed amount of washed rice and pouring a fixed amount of water, the rice cooking container 34 is transferred to the washed rice water absorption conveyor device by the drive roller D, thereby absorbing an appropriate amount of water into the washed rice.
After being preheated by exhaust heat from the next continuous rice cooking device, the rice is transferred to a roller conveyor, and from this roller conveyor, the rice is transferred to the continuous rice cooking device for cooking.

The automatic switching valve 22 is opened and closed by a switching lever 30 during the rice washing and finishing processes, and this switching lever 30 is automatically operated by a guide cam rail 27 via a guide roller.

This guide cam rail 27 is bent and fixed in a substantially horizontal direction on the machine base, and controls the switching lever 30 of the automatic switching valve 22 that moves in cooperation with the plurality of water pressure rice washers 5 that simultaneously rotate as the turntable 10 rotates. It is supposed to be activated.

This invention is based on an automatic draining device 6 that is installed below the washed rice that is automatically drained together with water from the output pipe 26 of the water pressure rice washer 5.
In.

A small amount of washed rice is divided into each draining chamber SW between the several rotary blades 31 in the draining case 49, and the washed rice is sequentially received, and the washed rice is pushed by the several rotary blades 31, uniformly and efficiently. Can be drained and dehydrated.

Therefore, a certain amount of washed rice that has been reliably and uniformly dehydrated is automatically flowed into the rice cooking container, and the mixing of this certain amount of washed rice and the added fresh water is performed accurately, and the rice cooking operation using the continuous automatic rice cooking device using the rice cooking container is performed. It has great practical benefits, such as being able to cook food evenly.
