Description

Technical Field

[0001] This utility model relates to the field of automated rice preparation, specifically to a fresh rice production line and its feeding device. Background Technology

[0002] With social progress and an increasingly fast pace of life, people have higher and higher demands for industrialized food products such as pre-cooked meals and self-heating rice. In recent years, the development of pre-cooked meals has been rapid, and intelligent and automated factories have emerged. However, the industrial production of self-heating rice faces certain challenges due to the numerous steps involved, such as removing impurities from the rice, selecting high-quality rice, soaking it, and cooking it.

[0003] In existing self-heating rice processing methods, some methods utilize a reprocessing technique where rice grains are crushed, mixed with starch (such as corn or potato starch), and then extruded into rice grains. This process shortens heating time and avoids the problem of raw rice not gelatinizing quickly, but it doesn't meet the demand of consumers for the authentic flavor. Other methods use a mixed rice and water cooking process, but this is relatively simple and has many problems.

[0004] For example, CN108850846A discloses a self-heating rice production line that includes a rice washing device, a rice soaking device, a filling device, a microwave cooking device, a sealing device, and a secondary cooking and sterilization device. The rice washing device delivers washed rice to the rice soaking device, which then delivers the soaked rice to the filling device. The filling device quantitatively delivers the soaked rice and nutrient solution to the cooking box. The microwave cooking device heats and cooks the rice and nutrient solution in the cooking box, actively releasing steam after the rice is evenly cooked to accelerate the dissipation of the nutrient solution. The sealing device seals the cooking box containing the cooked rice to obtain a semi-finished product. The secondary cooking and sterilization device performs high-temperature sterilization and secondary cooking. In this production line, the rice enters the rice washing device by direct falling, which prevents further separation of dust and other impurities from the rice in the rice bin. This results in the rice failing to achieve the required cleanliness, thus affecting the taste of the cooked rice. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a fresh rice production line and its feeding device.

[0006] According to the present invention, a feeding device for a fresh rice production line includes an elevator, a storage tank, a first conveying mechanism, and a first storage and conveying mechanism.

The inlet of the pump is connected to the discharge port of the storage tank and the discharge port of the pump is connected to the inlet of the conveying tank. The first conveying pipe is a J-shaped pipe and the horizontal pipe opening of the first conveying pipe is connected to the discharge port of the conveying tank.

[0008] The vertical pipe opening of the first conveying pipe is used to connect with the feed inlet of the first storage compartment of the first storage conveying mechanism. After the pump pumps the finely screened rice in the storage tank into the conveying tank, the finely screened rice is conveyed from the low position to the first storage compartment at the high position through the first conveying pipe.

[0009] In some embodiments, the storage tank is composed of an upper cylinder and a lower cone connected together, the conveying tank is located below the storage tank, and the funnel opening of the lower cone of the storage tank is connected to the feed inlet of the pump.

[0011] In some embodiments, there are two storage tanks, and the elevator is connected to the two storage tanks via pipes.

[0012] In some embodiments, the first storage compartment is located above the upper surface of the storage tank.

[0013] In some embodiments, the first material conveying mechanism further includes a second conveying pipe, an auxiliary pipe, and a first switching valve.

[0014] This utility model also provides a fresh rice production line, which uses the feeding device for the fresh rice production line.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model relates to a feeding device for a fresh rice production line. The device uses a J-shaped conveying pipe to transport finely sieved rice in an anti-gravity manner. During the conveying process, light impurities such as dust and empty, damaged rice grains are lifted upwards by the pressure air and separated. Heavy particles such as stones are trapped during the transition from horizontal to vertical motion and during the vertical motion. This results in fewer impurities in the rice grains entering the storage tank, and the grain size tends to be uniform, improving the taste and appearance of the cooked rice.

[0019] Figure 2 This is a side view of the feeding device of this utility model. Detailed Implementation

[0020] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0021] This embodiment provides a feeding device for a fresh rice production line, such as... Figure 1-2 As shown, the system mainly includes an elevator 1, a storage tank 2, a first conveying mechanism 3, and a first storage and conveying mechanism 4. The elevator 1 is located on one side of the storage tank 2. The elevator 1 lifts the finely screened rice from the upstream process from the bottom to the top, and then conveys the finely screened rice into the storage tank 2 through a conveying pipe connected to the storage tank 2. The storage tank 2 is a tank composed of an upper cylinder and a lower cone. The finely screened rice is conveyed into the storage tank 2 by the elevator 1. In this embodiment, two sets of storage tanks 2 are fed by one set of elevators 1. The elevator 1 can be controlled via a three-way connector to first convey a predetermined amount of rice to one set of storage tanks 2, and then convey it to the other set. During the process of conveying rice to the other set of storage tanks 2, the rice received in the first set of storage tanks 2 can be used for output, improving production efficiency.

[0022] The first conveying mechanism 3 mainly includes a pump 31, a conveying tank 32, and a first conveying pipe 33. The conveying tank 32 is located below the storage tank 2. The inlet of the pump 31 is connected to the outlet at the bottom of the conical tank of the storage tank 2, and the outlet of the pump 31 is connected to the inlet at the top of the conveying tank 32. Finely screened rice enters the conveying tank 32 through the pump 31. While pumping the finely screened rice into the conveying tank 32, the pump 31 also pumps air into the conveying tank 32, creating a positive pressure state inside the conveying pipe 32. The first conveying pipe 33 has a J-shaped structure. The inlet port at the horizontal part at the bottom of the first conveying pipe 33 is connected to the outlet of the conveying tank 32, and the outlet port at the vertical part at the top of the first conveying pipe 33 is connected to the inlet of the first storage chamber 41 of the first storage and conveying mechanism 4 via a pipe. While pumping 31 delivers sieved rice into conveying tank 32, air at a predetermined pressure is simultaneously introduced. This causes the sieved rice, entering the first conveying pipe 33 from tank 32, to be propelled upwards along the J-shaped inner cavity of the first conveying pipe 33 into the first storage chamber 41 by the pressurized air. The J-shaped conveying pipe 32 delivers the sieved rice using an anti-gravity method. During this process, light impurities such as dust and empty, damaged rice grains are lifted upwards by the pressurized air and separated. Heavy particles such as stones are trapped during the transition from horizontal to vertical motion and during the vertical motion itself. This results in fewer impurities in the rice grains entering the storage tank, and the grains are more uniform in size, effectively improving the taste and appearance of the cooked rice.

[0023] The first storage chamber 41 is mounted above the upper opening of the storage tank 2 via a bracket. Preferably, the first storage chamber 41 is mounted above the end cap of the storage tank 2 via a bracket. This installation utilizes the structure of the storage tank 2, making it simple, convenient, and cost-effective. The first storage and conveying mechanism 4 also includes a second conveying pipe 42. The lower opening of the first storage chamber 41 is connected to the inlet of the second conveying pipe 42 via a valve. The outlet of the second conveying pipe 42 is connected to the inlet of the rice washing machine at the rice washing station. The valve is used to control the amount of material entering the rice washing mechanism from the first storage chamber 41. In some embodiments, the first storage and conveying mechanism 4 is also provided with an auxiliary pipe 43 and a first switching valve 44. The inlet end of the auxiliary pipe 43 is connected to the pipe body of the second conveying pipe 42 to form a Y-shaped structure. The first switching valve 44 is a three-way valve, installed on the auxiliary pipe 44, and used to control the opening and closing of the auxiliary pipe 44 or the second conveying pipe 42. The first switch valve 44 controls the auxiliary pipe 43 to be in a normally closed state and the second conveying pipe 42 to be in a normally open state. When the second conveying pipe 42 is blocked while conveying the rice-water mixture or when cleaning the first storage tank 41, the first switch valve 44 closes the second conveying pipe 42 and opens the auxiliary pipe 43 at the same time to discharge the blockage or cleaning material from the auxiliary pipe 43, which facilitates the maintenance and management of the production line.
