Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, and in particular relates to a low-sugar rice steamer. Background Technology

[0002] Rice is a common staple food in people's diets and a major source of energy and sugar for the human body. The main nutritional component of rice is carbohydrates, accounting for about 75%, thus providing the primary source of calories for our daily lives. However, with improved living standards, more and more people are pursuing healthier lifestyles and are gradually realizing that rationally controlling sugar and calorie intake is a healthier way of eating.

[0003] Currently, rice cookers heat rice and water together in the inner pot. After the rice is cooked, the starch in the rice is converted into sugar, resulting in a high sugar content. This is not in line with a healthier diet and is not suitable for diabetics or obese patients. Therefore, it is necessary to develop low-sugar rice cooking equipment that meets these requirements.

[0004] However, most of the low-sugar rice cooking equipment on the market is for home use, namely rice cookers. For commercial markets such as canteens, restaurants, and hospitals that supply large quantities of rice, there is a lack of products that can meet the needs of commercial and large canteens for steaming and cooking low-sugar rice. In today's world where kitchen space is scarce and labor costs are rising, large-scale rice production requires multiple tools, equipment, and manpower throughout the process. Therefore, it is necessary to provide a rice steamer that can steam rice in large quantities and achieve low sugar content. Utility Model Content

[0005] This invention provides a low-sugar rice steamer to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A low-sugar rice steamer includes a cabinet body equipped with lockable omnidirectional casters and a rice steaming tray, as well as a bracket, heating element, and water injection module installed inside the cabinet body. The bracket inside the cabinet body has multiple layers, capable of holding multiple rice steaming trays. The rice steaming tray has a double-layer filter structure. The water injection module includes a water outlet plate located at the top of the cabinet body. The bottom of the cabinet body has a water tank structure, with heating element and multiple water level probes arranged within the tank, and openings for mounting an overflow valve, water supply pipe, and drainage pipe. The cabinet body also has a vent valve and a programmable controller with a touch-screen display.

[0008] Preferably, the double-layer filter structure of the rice steaming tray is divided into an upper filter plate and a lower filter plate. The filter holes in the upper filter plate are small holes, and the area of ​​the holes is located in the center of the upper plate, accounting for 20% to 40% of the bottom area of ​​the upper plate. The filter holes in the lower filter plate are large holes, accounting for 80% to 95% of the bottom area of ​​the lower plate.

[0009] Preferably, the water injection module consists of a water outlet plate, a water delivery pipe, a jet centrifugal pump, and an inlet solenoid valve.

[0010] Preferably, one end of the water inlet solenoid valve is connected to the water inlet pipe, and the other end is connected to the jet centrifugal pump through a pipe. The jet centrifugal pump is connected to the water outlet plate set at the top of the cabinet cavity through a water delivery pipe.

[0011] Preferably, the plurality of water level probes are positioned on the inner wall of the water tank in a horizontally ascending manner with intervals from low to high.

[0012] Preferably, the programmable controller controls the operation of the water injection module, the water level probe, and the solenoid valve in the drainage pipe.

[0013] Preferably, the cabinet doors of the cabinet are fitted with transparent viewing glass.

[0014] Preferably, the water outlet plate and the rice steaming tray placed on the bracket are both on the same vertical line inside the cabinet.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] This invention relates to a commercially viable rice steamer for large-scale rice cooking. Through its rational design, it achieves a low-sugar cooking effect that most rice steamers lack. Compared to using common low-sugar rice cookers to achieve low sugar content, this invention saves equipment and manpower while cooking large quantities of rice, and reduces sugar content during the process.

[0017] This utility model is equipped with a programmable controller with a touch screen. It realizes water intake, rice washing, rice draining, steaming, and drainage through preset workflow and control data. More importantly, it can control the water injection module to inject room temperature water from top to bottom to wash the raw rice in the steaming tray. During the rice draining process, the flowing and circulating high temperature water removes soluble glucose and starch, reducing the total sugar content. Subsequently, through the phenomenon of steam condensation, the water evaporated after boiling flows from top to bottom, cooking the rice multiple times. This process removes the soluble sugars from the rice, thereby further reducing the sugar content. In addition, based on the vertical arrangement of the steaming chamber, it saves kitchen space and allows the initial room temperature water or the subsequent condensed water to flow from top to bottom through each steaming tray by gravity to remove a certain amount of sugar, further reducing the overall sugar content.

[0018] This utility model can automatically match the corresponding water and electricity according to different loads, i.e. the number of rice steaming trays, to complete the steaming process of low-sugar drained rice, so as to achieve the purpose of energy saving and intelligent steaming.

[0019] This utility model is equipped with a solenoid valve, a vent valve, an overflow valve, and a water level probe. In conjunction with a programmable controller, it can provide real-time monitoring feedback to trigger alarms or open relevant valves to release air or water, greatly improving intelligence and safety.

[0020] The cabinet doors of this utility model are fitted with transparent viewing glass, which makes the overall appearance more beautiful and allows direct observation of the steaming process. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 8 As shown, this utility model is a low-sugar rice steamer, which mainly consists of a cabinet body 1 equipped with lockable omnidirectional casters 10, rice steaming trays 2, and a bracket 3, heating element 4, and water injection module installed inside the cabinet body 1. To ensure large-volume rice steaming, the bracket 3 inside the cabinet body 1 has multiple layers to accommodate multiple rice steaming trays 2, providing a basic steaming capacity. Furthermore, this utility model can automatically match the corresponding water and electricity amounts according to different load capacities, i.e., the number of rice steaming trays 2, to complete the steaming process of low-sugar rice, achieving energy saving and intelligent steaming. Furthermore, the bottom of the inner cavity of the cabinet 1 is designed as a water tank 11. The inner cavity of the water tank 11 is equipped with heating tubes 4 and multiple water level probes 6, and also has openings for mounting overflow valves 7, water supply pipes 8 and drainage pipes 9 respectively. The cabinet 1 is also equipped with a vent valve 14 and a programmable controller with a touch display screen 13. This structural design allows the present invention to have basic heating and steaming functions while ensuring water discharge or circulation and meeting standard safety requirements. The vent valve 14 is a pressure valve, located in the upper part of the cabinet 1. The steam generated by heating will rise and accumulate at the top of the inner cavity of the cabinet 1. When the internal air pressure is greater than the set value during operation, the vent valve will automatically open to ensure timely venting and thus ensure safety. Similarly, the overflow valve 7 is equipped with a float valve, which can discharge excess hot water in time when the water level in the water tank 11 reaches its inlet, preventing hot water from overflowing and scalding personnel when the operator opens the cabinet door due to excessively high water level during operation. It can be further explained that after the rice steaming tray 2 is removed, the water in the water tank 11 is discharged through the drain pipe 9, and the drain pipe 9 is equipped with a solenoid valve. Based on the program data set by the programmable controller, the solenoid valve can automatically open after the rice is steamed to drain the water, so as to prevent bacteria from growing inside or even being reused.

[0031] The key point of this utility model is that it achieves the low-sugar rice cooking function of a rice steamer through a reasonable structural design, thereby addressing the needs of commercial markets such as canteens, restaurants, and hospitals that supply large quantities of rice. It provides a healthier diet while also catering to diabetics or obese patients. Its main features are as follows:

[0032] 1. The rice steaming tray 2 has a double-layer filter structure, specifically divided into an upper filter plate 20 and a lower filter plate 21. The filter holes in the upper filter plate 20 are small holes, and the area of ​​the holes is located in the center of the upper layer, accounting for 20% to 40% of the bottom area of ​​the upper filter plate 20. The filter holes in the lower filter plate 21 are large holes, accounting for 80% to 95% of the bottom area of ​​the lower filter plate 21. This design ensures that the water added by the water injection module from top to bottom, or the water formed by steam condensation, can flow from the top rice steaming tray 2 to the bottom rice steaming tray 2. The water injection module adds room temperature water to wash the raw rice first. The flowing and circulating water removes soluble glucose and starch, reducing the total sugar content. The water formed by steam condensation is high temperature water, which heats and rinses the rice during the steaming process, removing the soluble sugars from the rice, thereby further reducing the sugar content of the rice.

[0033] Second: The water used for washing rice and the water generated during steaming are collected in the water tank 11. The bottom of the water tank 11 is equipped with a heating element 4. Its purpose is to repeatedly heat the water in the water tank 11 to a certain temperature during the steaming process, even when the water injection module has stopped adding water. This design is for water circulation. The heated water forms steam, which rises and comes into contact with the rice, humidifying and heating it. When the steam reaches the top of the cabinet 1, it condenses. The water formed by the steam falls into the top steaming tray 2. When the rice has sufficient moisture content, the water formed by the condensation of steam will flow from top to bottom to the bottom steaming tray 2, and finally fall into the water tank 11. This design can maximize the use of heat efficiency while heating and rinsing the rice multiple times during the steaming process. It can be further explained that when the water injection module washes and drains the raw rice at the beginning, it can allow the raw rice to absorb a certain amount of water to ensure the moisture content, thereby shortening the steaming time and increasing the sugar that can be removed during the steaming process.

[0034] 3. The water injection module consists of a water outlet plate 5, a water supply pipe 8, a jet centrifugal pump 51, and a water inlet solenoid valve 52. One end of the water inlet solenoid valve 52 is connected to the water inlet pipe, and the other end is connected to the jet centrifugal pump 51 through a pipe. The jet centrifugal pump 51 is connected to the water outlet plate 5 located at the top of the inner cavity of the cabinet 1 through the water supply pipe 8. The jet centrifugal pump 51 is set to ensure that the water pressure is sufficient to pump water from bottom to top into the water outlet plate 5 for rice washing.

[0035] Fourthly, this utility model is equipped with a solenoid valve, a vent valve 14, an overflow valve 7, and a water level probe 6. In conjunction with a programmable controller, it can provide real-time monitoring feedback to trigger alarms or open relevant valves to vent or release water, greatly improving intelligence and safety. To facilitate monitoring, there are multiple water level probes 6. These multiple water level probes 6 are installed on the inner wall of the water tank 11 in a horizontally ascending, spaced-out manner from low to high, to effectively monitor changes in water level.

[0036] Fifthly, in the rice draining stage of this invention, the programmable controller first heats the water to a high temperature but not to boiling state. At this time, the soluble sugars are not dissolved by steam condensation, but by the continuous circulation of hot water to rinse the rice. During the process of rinsing with high-temperature water, the raw rice gradually becomes cooked rice. During this process, the rice will continuously release glucose and starch. At this time, the circulating high-temperature water can dissolve and remove most of the soluble glucose and starch, thereby reducing the sugar content. The rice is not cooked during the draining stage. However, when the draining time controlled by the programmable controller is reached, the steaming stage begins. At this time, the water is boiling. The steaming stage can maximize the phenomenon of steam condensation. This stage will continue until the rice is cooked, which is specifically controlled by the programmable controller.

[0037] In addition, it can be mentioned that the water outlet plate 5 and the rice steaming tray 2 placed on the bracket 3 are all on the same vertical line inside the cabinet 1. This design ensures that the water vapor can rise vertically and the water flowing down can evenly contact each layer of rice, while making full use of the vertical space to save kitchen space. Furthermore, the cabinet door of the cabinet 1 is fitted with transparent viewing glass 12, which makes the whole more beautiful and allows direct observation of the steaming process.
