Description

Technical Field

[0001] This utility model relates to the field of parboiled rice processing technology, and in particular to a steaming and drying device for parboiled rice processing. Background Technology

[0002] Parboiled rice, made from indica rice, undergoes a process involving cleaning, soaking, steaming, and drying, followed by conventional hulling and milling. It is a pure, natural, and nutritious type of rice, also known as semi-cooked rice. After hydrothermal treatment, parboiled rice becomes harder, resulting in a lower breakage rate and higher yield. The yield can increase by 1% to 2% compared to brown rice. Steaming makes the husks softer and easier to remove, increasing the efficiency of rice hulling machines by about 30%. The oil yield from parboiled rice is higher than that from regular rice. The finished rice grains are transparent and glossy, with improved nutritional content. The vitamin and mineral content in the endosperm is increased, and vitamin B is more evenly distributed within the grain. Vitamin B1 and B2 content is four times higher than in regular rice, and niacin content is eight times higher. Parboiled rice produces rice with good expansion properties, is easily digestible, and has a high yield. After steaming, the yield of japonica rice is about 40% higher than that of regular rice, and that of indica rice is about 45% higher. Less solid matter remains in the water during steaming, resulting in loose, glossy grains with the distinctive flavor of steamed rice. Because the hydrothermal treatment kills microorganisms and pests, and also eliminates its germination ability, the rice is easier to store, preventing sprouting and mold growth.

[0003] Currently, traditional processing methods are no longer suitable for the current processing model. They have low automation, low efficiency, and poor parboiled rice processing results. How to achieve high-efficiency and high-quality processing has become an important issue. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1-3 A steaming and drying device for processing parboiled rice includes a heating base 1, a rotary motor 4 mounted on the heating base 1, a connecting plate 5 mounted on the output end of the rotary motor 4, two sets of material trays 3 mounted on both ends of the connecting plate 5, an exhaust assembly 2 and a steam assembly 6 symmetrically mounted on both sides of the rotary motor 4, the outer frame of the material trays 3, the outer frame of the exhaust assembly 2 and the side wall contour of the steam assembly 6 are the same; an openable and closable top cover 7 is mounted above the steam assembly 6.

[0023] Open the top cover 7 of the steam assembly 6, and evenly place the parboiled rice to be processed into the corresponding tray 3 of the steam assembly 6. Then close the top cover 7 to ensure a good seal and prevent steam leakage. During the cooking process, start the heating base 1 to heat the steam assembly 6. The water in the steam assembly 6 is heated to generate steam, which is sprayed onto the parboiled rice in the tray 3. After cooking, open the top cover 7, start the rotary motor 4, replace the tray 3 corresponding to the exhaust assembly 2 and the steam assembly 6, and place the material into the empty tray 3 to carry out the cooking step. At the same time, start the exhaust assembly 2 to blow the heat generated by the heating base 1 onto the cooked material to dry it. After drying, remove the material and repeat the above steps.

[0024] The rotating motor 4 drives the material tray 3 to rotate, thereby replacing the exhaust component 2 and the steam component 6 with the corresponding material tray 3. This allows for the simultaneous cooking of one set of materials and the drying of another set of cooked materials. Furthermore, new materials can be added and cooked simultaneously during the drying process, enabling parallel and cyclical cooking and drying processes. This significantly improves the processing efficiency of parboiled rice, shortens the overall processing cycle, and meets the needs of large-scale production.

[0025] The heating base 1 directly heats the steam assembly 6, resulting in more concentrated and efficient heat transfer compared to traditional decentralized heating methods, thus reducing heat loss. Simultaneously, the exhaust assembly 2 directs the heat generated by the heating base 1 to the material to be dried, improving heat utilization efficiency.

[0026] The outer frame outlines of the material tray 3, exhaust assembly 2, and steam assembly 6 are identical, which not only makes the device structure compact and space-saving, but also ensures a smooth transition during the replacement of the material tray 3, avoiding compatibility issues caused by structural differences. The components work together to form an integrated processing flow from cooking to drying, simplifying operation steps and reducing the difficulty of manual operation.

[0027] In other preferred embodiments, the material tray 3 includes a first outer frame, a support tray, and a connecting ring. The bottom surface of the support tray is a screen. The support tray is connected to the first outer frame through the connecting ring. The first outer frame, the support tray, and the connecting ring form a return trough. A leakage hole is provided at the bottom of the return trough. The lower end face of the top cover 7 is conical, and the height of the middle of the lower end face of the top cover 7 is higher than the height of the surrounding area.

[0028] By setting a screen structure on the bottom surface of the bearing plate of the feed tray 3, good air permeability is ensured during the cooking process of parboiled rice, which is conducive to the uniform penetration of steam into the material, so that the parboiled rice is heated more fully and the cooking effect is improved.

[0029] The lower end face of the top cover 7 has a conical structure that is high in the middle and low around the edges. When the steam assembly 6 is working, the water vapor that accumulates under the top cover 7 is guided to the edge position and flows back into the return groove. Together with the leakage hole at the bottom, it flows back into the steam assembly 6.

[0030] In other preferred embodiments, the inner surface of the tray 3 is provided with an anti-stick coating, which is a polytetrafluoroethylene coating, to prevent parboiled rice from sticking to the tray 3 during the cooking and drying process.

[0031] In other preferred embodiments, the top cover 7 is made of transparent material, and the top cover 7 is fixedly connected to one end of the L-shaped plate, while the other end of the L-shaped plate is hinged to the heating base 1.

[0032] In other preferred embodiments, the exhaust assembly 2 includes an exhaust fan and a second outer frame, the second outer frame being an annular baffle; the exhaust fan is disposed within the second frame, and a filter screen is disposed on the top of the second frame. The filter screen prevents materials from falling into the exhaust assembly 2 and affecting its operation.

[0033] In other preferred embodiments, the steam assembly 6 is a barrel with an open top, and the height of the barrel is the same as the height of the outer frame of the exhaust assembly 2.

[0034] In other preferred embodiments, the bottom of the heating base 1 is provided with several height-adjustable support feet. Each support foot includes a threaded post and an adjusting sleeve fitted on the threaded post. The adjusting sleeve is fixedly connected to the bottom of the heating base 1 by bolts, and a shock-absorbing pad is fixedly connected to the bottom of the support foot.

[0035] In other preferred embodiments, the heating base 1 is hollow inside, and a combustion chamber is provided on the rear side of the heating base 1. The hollow structure of the heating base 1 provides a good channel for heat transfer, and the heat generated by the combustion chamber can be quickly and evenly distributed to all parts of the heating base 1, and then efficiently transferred to the steam assembly 6 and the exhaust assembly 2.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
