Description

Technical Field

[0001] The present invention relates to the technical field of catering equipment, and particularly to an ancient method rice steamer. Background Art

[0002] Currently, the supply of rice in the industry mainly focuses on traditional rice cooking or steaming. For large-scale rice supply, steaming is more common. However, the taste of current traditional steamed rice is not good, the quality of the rice is difficult to control, and the quality requirements for the rice are relatively high, that is, the cost of the rice is high.

[0003] When steaming a large amount of rice, there is no dedicated equipment on the market that can save manpower for steaming rice. Especially after the steaming is completed, due to the large amount of rice, it is often impossible for one person to complete the action of scooping out the rice. Multiple people need to cooperate to scoop out the rice from the inner tank. In order to save the time of scooping out the rice, even shovels are used for digging. This way of steaming rice can easily cause the rice in the central part not to get enough temperature, resulting in the phenomenon of undercooked rice. In particular, before steaming a large amount of rice, if the rice needs to be mixed with other materials such as seasonings, soybeans and other auxiliary materials, it needs to be done manually and cannot be well combined with the rice steaming equipment, which has a large workload and wastes human resources.

[0015] The advantages of the ancient method rice cooker provided by the present invention are as follows: The present invention is convenient to use and simple to operate. It can steam rice in large quantities, is convenient to take out the steamed rice, and saves labor. The specific beneficial effects are as follows:

[0016] 1. By setting the inner container, the inner container is designed in the form of a combination of a first hemisphere, a second hemisphere and a connecting shaft. The rice is directly put into the cavity of the spherical inner container formed by the first hemisphere and the second hemisphere. The first hemisphere and the second hemisphere are hermetically sealed. When the spherical inner container is in use, it can be driven by an external driving mechanism and can rotate freely without spilling the internal rice. While rotating, the inner container is heated by steam, and the steam can heat the entire outer surface of the inner container, so that the internal rice is evenly heated, making it easier to steam the rice and improving work efficiency. Put the soaked rice grains into the inner container without adding water. During the rotation process, the rice grains remain in a moving and tumbling state. During the steaming process, the rice grains will not stick together into a whole block. When the rice is steamed, directly open the first hemisphere and the second hemisphere, and the internal rice will directly fall from the gap into the mixing device without sticking into a block and does not need to be taken out manually, which is convenient, fast and effective.

[0017] 2. The inner container driving device is designed in the form of a combination of a first servo motor, a rotating shaft, a lead screw, a second servo motor and a bearing. The first servo motor drives the rotating shaft to act, driving the inner container to rotate. While the inner container rotates, it can tumble the rice inside. The outer surface of the inner container can evenly obtain external steam, so that the internal rice is evenly heated, and the phenomenon that the rice near the outer layer is steamed and the internal rice is not cooked in the prior art will not occur. Moreover, through rotation, the internal rice will not form lumps after being steamed and is in a loose state.

[0018] 3. By controlling the forward and reverse rotation of the second servo motor to drive the lead screw, the gear of the second servo motor drives the lead screw, so that the lead screw can move back and forth along the axis direction of the rotating shaft. The lead screw is connected to the rotating shaft through a bearing. Since the inner hole wall of the bearing is fixed on the outer wall of the rotating shaft and its outer wall is fixed on the inner wall of the lead screw, the back and forth movement of the lead screw drives the rotating shaft to move back and forth along its own axis direction, and the back and forth movement of the rotating shaft can drive the two hemispherical covers of the inner container to open and close each other.

[0019] 4. By setting the bearing, when the first servo motor acts, the second servo motor is turned off, and its gear limits the position of the lead screw. The first servo motor drives the rotating shaft to support and rotate through the bearing, and the two hemispherical covers of the inner container will not open and close each other due to the action of the lead screw. On the contrary, when the second servo motor acts, the first servo motor is turned off, and the gear on the first servo motor limits the rotation of the rotating shaft. The forward and reverse installation of the second servo motor drives the rotating shaft to move.

[0020] 5. When controlling the opening and closing of the first or second hemisphere by moving back and forth through the rotating shaft, the loose rice inside can be directly unloaded under the action of gravity, without the need for manual scooping, which is convenient, fast and effective.

[0021] 6. By designing the mixing device in the form of a combination of a cylindrical container, a cover, a feeding plate, a driving device, a combined rotating shaft and a stirring blade, the cylindrical container receives the rice released from the inner container. Then, seasonings or other auxiliary materials, such as soybeans and other crops, can be manually added. After putting them into the cylindrical container, directly start the second motor and the third motor, drive the outer shaft sleeve to rotate and reciprocate axially, drive the stirring blade to rotate to stir the rice, and drive the stirring blade to move axially, so that the rice in the entire cylindrical container can be stirred evenly. When the stirring is even, steaming can continue. After steaming, stop the second motor and the third motor, control the action of the first motor, drive the feeding plate to rotate, and the wing plates of the cover on the feeding plate are rotated and affected by the gravity of the rice, and the wing plates are opened, thus opening the cover. After the cover is opened, the rice falls from the opening on the feeding plate to the discharge port at the lower end of the cylindrical container, fully realizing automatic operation.

[0022] 7. The rice on the inner wall of the cylindrical container cannot fall automatically. To avoid waste, drive the second motor and the third motor to drive the stirring blade to rotate. The scraper on the stirring blade can scrape all the rice on the inner wall of the cylindrical container into the bottom of the cylindrical container to avoid waste of rice. When the amount of rice is too large, the first motor can be driven to operate to discharge a part of the rice, and then stop the operation of the first motor, and leave the remaining mixed rice in the cylindrical container for multi-batch supply, which is clean, hygienic and convenient to operate.

[0044] 1. By providing an inner container, the inner container is designed in the form of a combination of a first hemisphere, a second hemisphere and a connecting shaft. The rice is directly placed into the cavity of the spherical inner container formed by the first hemisphere and the second hemisphere. The first hemisphere and the second hemisphere are hermetically sealed with each other. When the formed spherical inner container is in use, it can be driven by an external driving mechanism and can rotate freely without spilling the internal rice. While rotating, the inner container is heated by steam, and the steam can heat the entire outer surface of the inner container, so that the internal rice is evenly heated, making it easier to steam the rice and improving work efficiency.

When the rice is steamed, directly open the first hemisphere and the second hemisphere, and the internal rice will directly fall from the gap into the mixing device without sticking together into a block and does not need to be taken out manually, which is convenient, fast and effective.

[0045] 2. The inner pot driving device is designed as a combination of a first servo motor, a rotating shaft, a lead screw, a second servo motor, and a bearing. The first servo motor drives the rotating shaft to act, driving the inner pot to rotate. While the inner pot rotates, the rice inside can be tumbled, and the outer surface of the inner pot can evenly obtain the external steam, enabling the rice inside to be evenly heated, and preventing the phenomenon in the prior art where the rice near the outer layer is cooked while the rice inside is uncooked. Moreover, through rotation, the cooked rice inside will not clump and will be in a loose state.

[0046] 3. By controlling the forward and reverse rotation of the second servo motor to drive the lead screw, the gear of the second servo motor drives the lead screw, enabling the lead screw to move back and forth along the axis of the rotating shaft. The lead screw is connected to the rotating shaft through a bearing. Since the inner wall of the bearing hole is fixed on the outer wall of the rotating shaft and its outer wall is fixed on the inner wall of the lead screw, the back-and-forth movement of the lead screw drives the rotating shaft to move back and forth along its own axis, and the back-and-forth movement of the rotating shaft can drive the two hemispherical covers of the inner pot to open and close.

[0047] 4. By setting the bearing, when the first servo motor operates, the second servo motor is turned off, and its gear limits the position of the lead screw. The first servo motor drives the rotating shaft to be supported and rotated by the bearing, preventing the two hemispherical covers of the inner pot from opening and closing due to the movement of the lead screw. Conversely, when the second servo motor operates, the first servo motor is turned off, and the gear on the first servo motor limits the rotation of the rotating shaft. The forward and reverse rotation of the second servo motor drives the rotating shaft to move.

[0048] 5.

[0049] 6. By designing the mixing device as a combination of a cylindrical container, a cover, a blanking plate, a driving device, a combined rotating shaft, and a stirring blade, the cylindrical container receives the rice released from the inner pot. Then, seasonings or other auxiliary materials, such as soybeans and other crops, can be manually added. After being placed in the cylindrical container, directly start the second motor and the third motor to drive the outer shaft sleeve to rotate and reciprocate along the axis, driving the stirring blade to rotate and stir the rice, and driving the stirring blade to move axially, so that the rice in the entire cylindrical container can be stirred evenly.

After the cover is opened, the rice falls from the opening on the blanking plate to the discharge port at the lower end of the cylindrical container, fully realizing automated operation.

[0050] 7. The rice on the inner wall of the cylindrical container cannot fall automatically. To avoid waste, the second motor and the third motor are driven to drive the stirring blades to rotate. The scraping plates on the stirring blades can scrape all the rice on the inner wall of the cylindrical container into the bottom of the cylindrical container, avoiding waste of rice.
