[0002] In scenarios where meals are prepared for a large number of people, such as in the military, mines, schools, and canteens of enterprises and institutions, a large amount of rice needs to be prepared. In order to improve efficiency, the traditional method of steaming rice has gradually been replaced by automated steaming machines, which can transport the washed rice inside. During the transportation process, the rice is steamed and stewed with hot steam, and finally the steamed rice is delivered. However, using only hot steam for steaming and stewing will not only waste a lot of heat, but also the efficiency of steaming rice is not high enough and the flavor of the rice is also affected. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a preheating device for a rice cooking and stewing machine in view of the above-mentioned technical deficiencies, which can preheat rice in advance, improve the utilization rate of heat, and improve the steaming and stewing efficiency and the flavor of rice.

DETAILED DESCRIPTION
[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0019] like Figure 1 As shown, a preheating device for a rice cooker and stew machine comprises a cooker and stew machine body 1 and a rice washer 2 located on the left side of the cooker and stew machine body 1, a cooking pool 3 and a water supply pipe 4 are fixed on the upper side of the cooker and stew machine body 1; a water supply nozzle 5 is connected to the water supply pipe 4; the water supply nozzle 5 is correspondingly arranged above the cooking pool 3; a scraper conveyor 6 is correspondingly installed inside the cooking pool 3; a raw material conveying mechanism is arranged between the rice washer 2 and the cooking pool 3;
[0020] like Figure 2-4 As shown, the raw material conveying mechanism includes a conveyor casing 7 arranged at the lower end of the discharge port of the rice washing machine 2; the conveyor casing 7 is fixedly connected to the cooking and stewing machine body 1 through a bracket 8; the conveyor casing 7 is an inclined structure with the left side lower and the right side higher; a net chain conveyor 9 is correspondingly installed inside the conveyor casing 7; baffles 10 are respectively fixed on the front and rear sides of the upper end of the conveyor casing 7; a receiving hopper 11 is fixed to the left part of the conveyor casing 7; the right end of the receiving hopper 11 is correspondingly fixedly connected to the left end of the baffle 10; the receiving hopper 11 is correspondingly received below the discharge port of the rice washing machine 2; the net chain conveyor 9 is correspondingly installed inside the conveyor casing 7; the front and rear sides of the upper end of the conveyor casing 7 are respectively fixedly connected; the receiving hopper 11 is correspondingly connected to the left end of the baffle 10; the receiving hopper 11 is correspondingly connected to the lower part of the discharge port of the rice washing machine 2; the net chain conveyor 9 is correspondingly installed inside the conveyor casing 7; the front and rear sides of the upper end of the conveyor casing 7 are respectively fixedly connected ... The left part of the conveyor 9 is connected to the bottom of the receiving hopper 11; the left end of the immersion tank 3 is connected to the bottom of the right part of the mesh chain conveyor 9; a preheating nozzle 12 is fixed in the cooking machine body 1; the immersion tank 3 supplies water to the preheating nozzle 12 through a water pipeline (the layout of the water pipeline is various, not marked in the figure), and the power for water supply in the water pipeline can be water pumping, air pressure power, etc. The specific selection can be set by technical personnel according to actual conditions, and this scheme does not limit it; the preheating nozzle 12 is correspondingly arranged above the mesh chain conveyor 9.
[0021] like Figure 1-2 As shown, in the present technical solution, after the rice washing machine 2 washes the raw rice, the washed raw rice is discharged from the discharge port of the rice washing machine 2, and can be smoothly discharged onto the mesh chain conveyor 9 with the guidance of the receiving hopper 11. The mesh chain conveyor 9 rotates clockwise to deliver the raw rice into the immersion pool 3, and the scraper conveyor 6 rotates counterclockwise to gradually transfer the raw rice delivered to the immersion pool 3 to the subsequent processing flow.
[0022] The subsequent processing flow is to continue to transport the rice and steam it using steam. Since the steam steaming structure is not a technical feature of this solution, the steam steaming structure in the cooking machine body 1 is omitted in the figure.
[0023] Hot water (about 90°C) can be injected into the boiling pool 3 through the water supply nozzle 5 to boil the rice for a period of time. The subsequent steaming time can be shortened by boiling, the utilization rate of heat can be improved, and the flavor of rice can be improved; the rising hot steam can also transfer heat to the hot water in the boiling pool 3, keep the water in the boiling pool 3 warm and heat it, and improve the utilization rate of steam heat. The water flowing into the water supply pipe 4 comes from the hot water used to produce hot steam in the cooking machine body 1.
[0024] The pushing of the scraper conveyor 6 can also prevent the rice sent by the net chain conveyor 9 from piling up at the left end of the cooking tank 3. The pushing can also produce a turning effect on the rice, thereby improving the cooking effect and efficiency.
[0025] When the raw rice is transported on the net chain conveyor 9, the preheating nozzle 12 sprays the rice slurry produced by the soaking and boiling pool 3 onto the net chain conveyor 9. Since the rice slurry has a certain temperature, it can preheat the rice during the transport process; the conveyor housing 7 is low on the left and high on the right, which ensures that the rice slurry fully soaks and preheats the raw rice during preheating, and avoids the situation where the raw rice is discharged into the soaking and boiling pool 3 before it is fully soaked and preheated. By preheating the raw rice, the utilization rate of heat is further improved, the time for subsequent steaming and stewing of rice is further shortened, and the efficiency is improved.
[0026] The heat source in the preheating process is the rice slurry in the immersion pool 3. The advantage is that on the one hand, it avoids the heat waste caused by using hot water alone. On the other hand, when hot water alone is used to spray the raw rice, the flowing water will take away more nutrients in the raw rice, while spraying the rice slurry in the immersion pool 3 can reduce the loss of nutrients (the nutrients in the rice slurry itself will be absorbed by the raw rice, and the nutrients lost by flushing the raw rice will be reduced).
[0027] In addition, since water is involved in both the preheating and the boiling process, it can clean the mesh chain conveyor 9 and the scraper conveyor 6, thereby improving the reliability during long-term operation.
[0028] like Figure 3 As shown, a limiting opening 13 is opened at the lower right end of the receiving hopper 11; the upper end of the limiting opening 13 is higher than the upper end of the mesh chain conveyor 9 and lower than the upper end of the baffle 10. The distance between the limiting opening 13 and the mesh chain conveyor 9 can limit the thickness of the raw material rice spread on the mesh chain conveyor 9 to ensure the preheating effect.
[0029] like Figure 4As shown, the two baffles 10 are fixed with a limit bar 14 on the sides close to each other; the limit bar 14 is parallel to the right end of the receiving hopper 11; an adjustment plate 15 is provided on the right end of the receiving hopper 11; the adjustment plate 15 is slidably connected between the limit bar 14 and the receiving hopper 11; and a fixing bolt 16 is threadedly connected to the upper part of the adjustment plate 15. By sliding the adjustment plate 15 and locking the fixing bolt 16, the distance between the adjustment plate 15 and the mesh chain conveyor 9 can be changed, so that the thickness of the raw material rice spread when being transmitted through the limiting opening 13 can be further limited by the lower end of the adjustment plate 15, so that the thickness of the raw material rice spread on the mesh chain conveyor 9 can be adjusted more conveniently according to needs.
[0030] like Figure 2 As shown, an overflow pan 17 is fixed to the upper left side of the cooking machine body 1; the overflow pan 17 is correspondingly received below the right side outlet of the conveyor housing 7. The overflow pan 17 can receive the slurry flowing down from the conveyor housing 7 and the net chain conveyor 9 to ensure the sanitation of the working environment.
