Description

TECHNICAL FIELD

[0001] The utility model relates to the field of self-heating rice, and in particular to a fresh rice production line and a rice filling device thereof. BACKGROUND

[0002] With the progress of society and the acceleration of life rhythm, people's requirements for food industrial products such as prepared dishes and self-heating rice are getting higher and higher. In recent years, prepared dishes have developed rapidly, and intelligent and automated factories have appeared. However, the industrial production of self-heating rice is challenging because it needs to complete many steps such as removing impurities, selecting, soaking, and cooking rice.

[0003] In the existing self-heating rice processing, some use reprocessing technology for the rice grains in self-heating rice, that is, the rice is crushed and mixed with starch (such as corn and potato starch) to form rice grains. This treatment can shorten the heating time and avoid the problem of slow gelatinization of raw rice, but it is difficult to meet the requirements of the original flavor pursued by the majority of consumers. Some use a mixing and cooking process for rice and water, but there are many problems due to the simple design of the process.

[0004] For example, CN116982720A discloses a rice automatic production line, which includes a rice feeding machine, a rice washing machine, a filling machine, and a rice cooking machine connected in sequence. The utility model uses a quantitative hopper and a quantitative cylinder to measure the rice. Specifically, the mixture of rice and water enters the quantitative cylinder 314 from the discharge pipe through the adjusting pipe 301 and the quantitative hopper 302. The water is filtered out from the water filter hole and then discharged from the drain pipe. As the amount of rice increases, when the rice reaches the middle top of the quantitative hopper 302, and then fills the entire adjusting pipe 301, the rice cannot be discharged, and the quantitative feeding is completed. When the time is up, the electric valve 309 is closed, and then the flapper valve 307 is opened after a period of time. The rice falls into the rice cooking pot. The rice measuring and filling device disclosed in the utility model is still complex to operate and has low efficiency. UTILITY MODEL CONTENTS

[0005] In view of the defects in the prior art, the purpose of the utility model is to provide a fresh rice production line and a rice filling device thereof.

[0006] According to the rice filling device for the fresh rice production line, the metering and filling mechanism includes a fifth storage compartment, a metering drive motor, and a metering assembly. The metering assembly includes a carrier plate, a metering column, and a conveying hopper. The carrier plate is provided with a rice falling hole. The metering column is provided with a volume groove. The volume groove is a through-hole structure with an open top and bottom. The metering drive motor drives the metering column to slide linearly on the carrier plate.

[0007] After the wet rice is conveyed to the fifth storage compartment by the conveying mechanism and falls into the volume trough, the metering column is driven by the metering drive motor to slide a predetermined distance. Then, the volume trough is connected to the rice dropping hole, and the wet rice falls from the rice dropping hole into the lunch box through the conveying funnel.

[0008] In some embodiments, the metering component further includes a volume adjustment plate, which is slidably disposed within the volume trough. The amount of wet rice held in the volume trough can be changed by adjusting the position of the volume adjustment plate within the volume trough.

[0009] In some embodiments, the conveying mechanism includes a transfer pump, a fourth storage tank, and a first belt conveyor. The transfer pump transfers wet rice into the fourth storage tank. The conveyor belt of the first belt conveyor has an inclined structure design. The wet rice in the fourth storage tank falls onto the conveyor belt of the first belt conveyor and moves obliquely upward. During the oblique upward transport of the wet rice with the conveyor belt, rice and water are separated.

[0010] In some embodiments, a material distribution mechanism is also included, which includes a material distribution hopper and a second belt conveyor. The material distribution hopper is used to receive wet rice transported by the first belt conveyor and transport the wet rice to the second belt conveyor. The second belt conveyor is provided with multiple conveying channels. The metering and filling mechanism is in multiple sets, and each set of metering and filling mechanisms is adapted to the number of conveying channels of the second belt conveyor.

[0011] In some implementations, the rice filling device for the fresh rice production line described above is used.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through its volumetric metering and filling mechanism, not only provides a more accurate amount of rice, but also offers simple and convenient operation, effectively improving production efficiency. Furthermore, by setting an adjustable volume plate, the amount of rice can be changed according to actual conditions, eliminating the need to replace different metering instruments and effectively reducing production costs.

[0019] 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.

[0020] This utility model provides a rice-filling device, such as Figures 1-4 As shown, the system mainly includes a conveying mechanism 1 and a metering and filling mechanism 2. The conveying mechanism 1 mainly consists of a transfer pump 11, a fourth storage tank 12, and a first belt conveyor 13. The material inlet of the transfer pump 11 is connected to the outlet of the upstream pumping pipe, and its material outlet is connected to the material inlet of the fourth storage tank 12. After receiving the rice-water mixture pumped from the upstream pumping pipe, the transfer pump 11 transfers it to the fourth storage tank 12. The fourth storage tank 12 conveys the rice-water mixture from its outlet to the conveyor belt at one end of the first belt conveyor 13. As the rice-water mixture moves forward driven by the conveyor belt, the water and rice in the mixture are separated. In this embodiment, the first belt conveyor 13 is designed with an incline, and the belt carrying the rice-water mixture containing a small amount of water moves in an upward incline, which can further improve the separation rate of rice and water. The metering and filling mechanism 2 mainly consists of a fifth storage chamber 21, a metering drive motor 22, and a metering component 23. Wet rice conveyed from the first belt conveyor 13 to the end enters the fifth storage chamber 21, and the wet rice inside the fifth storage chamber 21 is discharged into the metering component 23 through its outlet. Figure 2As shown, the metering component 23 mainly consists of a carrier plate 231, a metering column 232, and a conveying funnel 233. The carrier plate 231 has a sliding groove, and the metering column 232 is slidably mounted on the carrier plate 231, with its lower surface in close contact with the upper surface of the carrier plate 231. The metering drive motor 22 drives the metering column 232 to slide on the carrier plate 231. The carrier plate 231 has a rice-dropping hole, and the upper end of the conveying funnel 233 is connected to the rice-dropping hole. The metering column 232 has a volumetric groove 2321, which is a through groove with open upper and lower ends. When rice is filled into the metering column 232, the wet rice slides from the outlet of the fifth storage chamber 21 into the volumetric groove 2321. At this time, the lower end of the volumetric groove 2321 is misaligned with the rice-dropping hole on the carrier plate 231, and the two are not connected. After the metering drive motor 22 drives the metering column 232 to slide a predetermined distance along the surface of the carrier plate 231, the lower opening of the volumetric trough 2321 communicates with the rice dropping hole on the carrier plate 231, allowing the wet rice in the volumetric trough 2321 to fall into the conveying funnel 233 through the rice dropping hole. The wet rice then slides from the conveying funnel 233 into the lunch box located below its outlet. In some embodiments, the metering component 23 is also provided with a volume adjustment plate 234, which is slidably disposed in the volumetric trough 2321. The volume adjustment plate 234 and the metering column 232 can be connected by a screw, facilitating the adjustment of the position of the volume adjustment plate 234 in the volumetric trough 2321. When filling the metering column 232 with rice, the metering drive motor 22 first drives the volume adjustment plate 234 to a predetermined position, and then adjusts the amount of wet rice entering the volumetric trough 2321. In this embodiment, the volumetric metering and filling mechanism not only provides a more accurate amount of rice, effectively improving production efficiency, but also allows for adjustments to the rice quantity based on actual conditions by using an adjustable volume plate, eliminating the need to change different metering instruments and effectively reducing production costs.

[0021] In this embodiment, a material distribution mechanism 3 is also provided, such as... Figures 3-4 As shown, the material distribution mechanism 3 includes a material distribution hopper 31 and a second belt conveyor 32, wherein there are two sets of second belt conveyors 32. The material distribution hopper 31 independently conveys materials to the conveyor belts of the two sets of second belt conveyors 32 through pipelines. Correspondingly, there are two sets of metering drive motors 22 and metering components 23, which are respectively set below the discharge port of the conveyor belt of the second belt conveyor 32, and receive the materials transported from the conveyor belt of the second belt conveyor 32 through the fifth storage tank 21. By setting up the material distribution mechanism, two rice cooking production lines can be formed simultaneously, which can effectively improve production efficiency and reduce manufacturing costs.
