Description

Technical Field

[0001] This utility model relates to the field of self-heating rice, specifically to a fresh rice production line and its rice washing 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 fails to meet the demand of consumers for the authentic flavor. Other methods use a mixed rice and water cooking process, but due to its relatively simple design, this method has several drawbacks.

[0004] For example, CN108850846A discloses a self-heating rice production line including 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 cooking box. The secondary cooking and sterilization device performs high-temperature sterilization and secondary cooking. In this production line, the rice washing process is placed after the rice soaking device, and the rice washing device uses a traditional stirring method. This not only easily damages the rice grains during stirring but also, due to the large volume in industrial production, makes it difficult for the rice 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 rice washing device.

[0006] According to the present invention, a rice washing device for a fresh rice production line includes a storage compartment, a rice washing component, and a conveying pipe.

[0007] The rice washing assembly includes a first rice washing tank and a second rice washing tank. The first rice washing tank is a cylindrical structure. The upper inlet of the first rice washing tank is connected to the lower outlet of the storage compartment. The storage compartment contains purified water. The upper inlet of the storage compartment is used to receive finely sieved rice. The first rice washing tank is provided with an air inlet. The second rice washing tank includes a first tank body with a cylindrical structure and a C-shaped conveying pipe connected to the first tank body. The lower inlet of the C-shaped conveying pipe is connected to the lower outlet of the first rice washing tank. The upper outlet of the C-shaped conveying pipe is connected to the upper inlet of the first tank body. The lower outlet of the first tank body is connected to the inlet of the conveying pipe.

[0008] External high-pressure gas enters through the air inlet. The rice-water mixture discharged from the first rice washing tank is pushed by the high-pressure gas and discharged into the first tank from bottom to top in a rotating manner along the inner cavity of the C-shaped conveying pipe. The rice-water mixture is then conveyed outward through the conveying pipe from the first tank.

[0009] In some embodiments, the second rice washing jar is a set of multiple sets, which are connected in series.

[0010] In some implementations, the number of the second rice washing jars is 3-5.

[0011] In some embodiments, the delivery pipe is a J-shaped pipe.

[0012] This utility model also provides a fresh rice production line, which uses the rice washing device for the fresh rice production line.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model rice washing device connects the first and second rice washing tanks in the rice washing mechanism through a C-shaped conveying pipe, allowing the rice-water mixture to rotate and flow under the action of high-pressure air. This is equivalent to using high-pressure air as a stirring element to agitate the rice and water. The high-pressure air entering the rice-water mixture will form bubbles. During the rotational flow of the rice-water mixture, the bubbles in the liquid will burst, and the bursting bubbles will have a scrubbing effect on the surface of the rice in the mixture, effectively improving the cleanliness of the rice after washing. At the same time, using high-pressure air as a stirring element will avoid the problem of trace impurities caused by friction due to agitation of solid agitators. Attached Figure Description

[0018] 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.

[0019] This embodiment provides a rice washing device for a fresh rice production line, such as... Figure 1-2 As shown, it mainly includes a storage tank 11 and a rice washing assembly 12. The storage tank 11 contains purified water, which receives finely screened rice from the upstream production line through the inlet. The finely screened rice entering the storage tank 11 mixes with the purified water to form a rice-water mixture. The storage tank 11 has a cylindrical upper section and a conical lower section structure. A valve is installed on the outlet pipe at the lower end of the storage tank 11 to control the inflow and outflow of materials. Figure 2As shown, the rice washing assembly 12 mainly consists of a first rice washing tank 121, a second rice washing tank 122, and a third conveying pipe 123. The first rice washing tank 121 is a cylindrical structure with its upper inlet connected to the lower outlet of the storage chamber 11. Its lower ends are respectively equipped with an air inlet 1211 and a discharge outlet 1212. High-pressure clean air is introduced into its cavity through the air inlet 1211, and the rice-water mixture inside the first rice washing tank 121 is discharged from the discharge outlet 1212 under the pressure of the high-pressure gas. The second rice washing tank 122 consists of a first tank body 1221, which is also a cylindrical structure, and a C-shaped conveying pipe 1222 connected to the first tank body 1221. The upper outlet of the C-shaped conveying pipe 1222 is connected to the upper inlet of the first tank body 1221, and its lower inlet is connected to the lower outlet of the first rice washing tank 121. The opening of the C-shaped conveying pipe 1222 faces the first rice washing tank 121. The rice-water mixture in the first rice washing tank 121 is propelled by high-pressure air and enters its cavity from the top of the first tank 1221 through the C-shaped conveying pipe 1221. The second rice washing tank 122 has a discharge port at its lower part, and the rice-water mixture is conveyed to the water filtration mechanism 2 through the third conveying pipe 123. The first rice washing tank 121 and the second rice washing tank 122 are connected by the C-shaped conveying pipe 1221, allowing the rice-water mixture to form a swirling flow under the action of high-pressure air. This is equivalent to using high-pressure air as a stirring element to stir the rice-water mixture. The high-pressure air entering the rice-water mixture will form bubbles. During the swirling flow of the rice-water mixture, the bubbles in the liquid will burst. The bursting bubbles will have a scrubbing effect on the surface of the rice in the mixture, effectively improving the cleanliness of the rice after washing. At the same time, using high-pressure air as a stirring element will avoid the problem of trace impurities caused by the friction of stirring with solid agitators. In this embodiment, there are multiple second rice washing containers 122, preferably 3-5, and all the second rice washing containers 122 are connected by C-shaped conveying pipes 1221. Multiple second rice washing containers 122 form a multi-stage circulating rice washing system, improving the rice washing effect.

[0020] In some preferred embodiments, the third conveying pipe 123 is designed with a J-shaped structure, which also conveys the rice-water mixture to the filtration mechanism in the downstream production line by means of anti-gravity. By conveying the rice-water mixture by means of anti-gravity through the J-shaped conveying pipe in the soaking mechanism, the collision and friction frequency between rice grains can be increased during the conveying process, and the bursting of air bubbles in the conveying pipe can clean the surface of the rice in the solution, forming a technical effect similar to rolling washing, improving the cleanliness of the rice surface and improving the taste of the cooked rice.
