Technical Field
[0001] The invention relates to the field of food processing, in particular to a plateau rice steaming cabinet. Background Art
[0002] A rice steamer is a large kitchen appliance that uses electricity or gas to heat and steam rice. It uses a stainless steel steaming tray (a square stainless steel tray) as its internal container. Universal wheels are installed underneath for easy mobility, giving it a cart-like appearance. The cabinet-shaped body is made of stainless steel, typically 304 stainless steel. Rice steamers are commonly used in large canteens such as hotels, military units, schools, and factories.
[0003] After massive searches, it was found that the prior art publication number is CN116473418A, which discloses a new type of fully automatic plateau pressurized rice steaming cabinet, including an inner pot, both sides of the inner surface of the inner pot are fixedly welded with brackets, a heating box is provided at the bottom of the inner pot, a water level regulating box and a heating plate are fixedly connected to the interior of the heating box, an air inlet pipe is fixedly connected to the surface of one side of the inner pot, a pressurizing valve is installed at one end of the air inlet pipe, a toggle switch is fixedly connected to the interior of the water level regulating box, a bracket is provided at one end of the water level regulating box, a lever is hingedly connected to the surface of one end of the bracket, and a floating ball is installed at one end of the lever. This scheme installs the water level regulating box by connecting the inner pot to the heating box, and combines the air inlet pipe and the pressurizing valve on the side to facilitate precise control of the water intake for electric heating, and steam can also be input for increase, while improving efficiency and safety, it is conducive to electrical dual use, has high adaptability, and is easy to control and use.
[0004] When the above-mentioned existing plateau rice steamer is in use, the rice to be steamed is placed in the rice steamer, and hot water is heated to boiling. However, in a plateau environment, the boiling point of water will decrease, resulting in a lower temperature of the steamed rice in the rice steamer, which will cause the air pressure in the rice steamer to increase to a suitable pressure for a longer time. At the same time, the steam in the rice steamer is from bottom to top, and the temperature received by the rice on the top layer is lower than that of the bottom layer, resulting in part of the food being overcooked and part being undercooked. Therefore, based on the above search and in combination with the existing problems, a plateau rice steamer is provided. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] See also Figures 1 to 8, a plateau rice steaming cabinet, comprising a cabinet body 1, a cabinet door 101 being rotatably mounted on the side end of the cabinet body 1, and a sealing ring being provided on the end of the cabinet door 101 close to the cabinet body 1 to keep the rice steaming cabinet sealed, and the sealing ring provided on the cabinet door 101 ensures the sealing of the rice steaming cabinet after the cabinet door 101 is closed, and a limiting block 102 is fixedly welded on the end of the cabinet door 101 away from the cabinet body 1, and a limiting handle 103 is threadedly provided on the end of the cabinet body 1 close to the limiting block 102, and the limiting handle 103 is threadedly installed to prevent the cabinet door 101 from bouncing open due to excessive air pressure in the rice steaming cabinet during the rice steaming process after the cabinet door 101 is closed, and a steaming placement mechanism 2 is provided inside the cabinet body 1 to evenly heat the food placed in the cabinet body 1 for heating, and a pressure control mechanism 3 is provided on the upper end of the cabinet body 1 to quickly increase the pressure inside the cabinet body 1 to an appropriate pressure after the cabinet door 101 is closed.
[0035] See also Figures 1 to 3 The steaming and placing mechanism 2 includes a placing slide rail 201, and the placing slide rail 201 is fixedly installed on the inner wall of the cabinet 1. A water tank 202 is slidably provided at the lower end of the cabinet 1. A drainage head 203 and a water inlet head 204 are fixedly installed at the side end of the water tank 202. The water inlet head 204 is an induction valve in the prior art. After the water inlet head 204 is connected to the water pipe, when the water in the water tank 202 is higher than the water inlet head 204, the water inlet head 204 is closed, and the water in the water pipe no longer enters the water tank 202. When the water in the water tank 202 is lower than the water inlet head 204, the water inlet head 204 is opened, and the water in the water pipe enters the water tank 202 for replenishment. The upper end of the slide rail 201 is slidably connected to the placement rack 205, and a plurality of heating grooves 206 are slidably connected to the inner wall of the placement rack 205.

[0036] See also Figures 1 to 4 , a heating pipe 208 is fixedly installed in the water tank of the heating tank 206, and a water inlet valve 209 is fixedly installed at the side end of the heating tank 206. A water hole 210 is provided inside the placement rack 205 near the water inlet valve 209, and the water hole 210 fits with the water inlet valve 209, so that after the heating tank 206 is installed in the placement rack 205, it is convenient for the placement rack 205 to pass water. A control end of the water inlet valve 209 is rotatably provided with a control rod 211, and a float 212 is fixedly installed at the end of the control rod 211 away from the water inlet valve 209, and the float 212 is arranged above the heating pipe 208. Specifically, when water is transferred to the heating tank 206 through the water inlet valve 209, the water level in the heating tank 206 rises, causing the float 212 to start rising. When the water level in the heating tank 206 is higher than the appropriate height, the float 212 changes the rotation angle of the control rod 211 to close the water inlet valve 209.
[0037] See also Figures 1 to 4 , a water transfer groove 213 is provided at the side end of the placement slide 201 near the water hole 210.

Near the lower end of the water tank 202, a connecting valve 216 is provided at the side end of the water tank 202 near the connecting head 215. The water inlet end of the connecting valve 216 is threadedly provided with a filter cartridge 217, and the filter cartridge 217 is provided with an activated carbon net for filtering microorganisms and debris. The above-mentioned connecting valve 216 is a prior art and will not be described in detail here. After the connecting head 215 is inserted into the connecting valve 216, the connecting valve 216 is opened. The retractable connecting head 215 makes it more convenient to install and remove the water tank 202.
[0038] See also Figures 1 to 6 The pressure control mechanism 3 includes a mounting box 301, and the mounting box 301 is fixedly mounted on the upper end of the cabinet 1. A ventilation gap is opened at the upper end of the cabinet 1, and a reflux rack 302 is fixedly mounted on the inner wall of the ventilation gap. The reflux rack 302 is arranged in a pyramid shape formed by connecting multiple rods, and a reflux pipe 303 is arranged at the lower end of the reflux rack 302. The reflux pipe 303 is away from the inner wall of the cabinet 1 away from the reflux rack 302, so that the water vapor evaporated during steaming contacts the reflux rack 302, and the water vapor condenses on the surface of the reflux rack 302, and then is transferred to the reflux pipe 303 along the reflux rack 302, thereby preventing the condensed water vapor from dripping into the rice at the top, resulting in excessive moisture in the rice at the top.
[0039] See also Figures 1 to 8 A detection cylinder 304 for detecting pressure is fixedly mounted on the inner wall of the installation box 301. A piston ring 305 is slidably mounted on the inner wall of the detection cylinder 304. A telescopic spring 306 is fixedly mounted between the piston ring 305 and the detection cylinder 304. When the piston ring 305 in the detection cylinder 304 moves, the air pressure in the cabinet 1 begins to change. The calculation formula is:
[0040] F=P×A
[0041] F represents the thrust of the gas pressure in the cabinet 1 in Newtons, N, P represents the pressure of the gas in the cabinet 1 in Pascals, Pa, and A represents the effective working area of the piston ring 305.
[0042] When the piston moves, the piston squeezes the telescopic spring 306. The formula for calculating the force of the telescopic spring 306 is:
[0043] F=kx
[0044] F represents the elastic force of the spring, and the unit is usually Newton N.
[0045] k represents the spring's elastic coefficient, also known as the spring constant, and is measured in Newtons per meter (N / m). It describes the elastic properties of the spring material and is a characteristic parameter of the spring.
[0046] x represents the deformation of the spring, that is, the distance the spring is compressed or stretched.
[0047] The air pressure in the cabinet 1 can be calculated using the above calculation formula.
[0048] A linkage rod 307 is fixedly mounted on one end of the piston ring 305 close to the spring telescopic rod. A resistance rod 308 is fixedly mounted on the upper end of the linkage rod 307 . An insulating sleeve 309 is provided on one end of the resistance rod 308 close to the linkage rod 307 .
[0049] See also Figures 1 to 8 , an electrified coil 310 is fixedly installed at the upper end of the installation box 301 near the resistance rod 308, a transmission wire 311 is fixedly installed at the side end of the electrified coil 310, and an air pressure pump 312 is fixedly installed at the end of the transmission wire 311 away from the electrified coil 310. Specifically, when the electrified coil 310 moves to the outer surface of the insulating sleeve 309, the air pressure pump 312 stops working. When the electrified coil 310 contacts the resistance rod 308, the farther away from the insulating sleeve 309, the higher the output power of the air pressure pump 312, so that the air pressure pump 312 can quickly adjust the air pressure in the installation box 301 to an appropriate size, and the air pressure pump 312 is fixedly installed at the upper end of the installation box 301, and a filter is fixedly installed at the input end of the air pressure pump 312. The filter prevents debris in the air from being transmitted to the installation box 301 through the air pressure pump 312.
[0050] See also Figures 1 to 8 The cam 314 is screwed onto the top of the pressure relief valve 314, and the cam 314 is screwed onto the top of the pressure relief valve 314. The cam 314 is screwed onto the top of the pressure relief valve 314, and the cam 314 is screwed onto the top of the pressure relief valve 314. The cam 314 is screwed onto the top of the pressure relief valve 314, and the cam 314 is screwed onto the top of the pressure relief valve 314. The cam 314 is screwed onto the top of the pressure relief valve 314, and the cam 314 is screwed onto the top of the pressure relief valve 314. The cam 314 is screwed onto the top of the pressure relief valve 314, and the cam 314 is screwed onto the top of the pressure relief valve 314.
[0051] The working principle of the present invention is as follows: when the rice steaming cabinet is needed, the material to be steamed is placed on the upper end of the placement rack 205, the pressure relief cylinder 314 is rotated and adjusted, and after the pressure relief cylinder 314 is rotated and adjusted to a suitable position, the cabinet door is closed, the resistance rod 308 is energized, and the air pressure pump 312 starts working to replenish air pressure in the cabinet body 1, so that the air pressure pump 312 quickly adjusts the air pressure in the installation box 301 to a suitable level;
[0052] When the air pressure in the cabinet 1 increases, the water in the water tank is transferred to the heating tank 206 through the connecting valve 216 and the water transfer pipe 214 under the action of the air pressure. The heating pipes 208 in the multiple heating tanks 206 start to work, evaporating the water in the heating tanks 206 to generate water vapor, which heats and cooks the ingredients on the shelf 205, thereby heating the food more evenly.
[0053] When the water in the heating tank 206 is heated and evaporated, the temperature in the cabinet 1 begins to rise, and the air pressure in the cabinet 1 begins to increase, the exhaust piston 316 moves to the exhaust groove opened at the upper end of the pressure relief cylinder 314, so that the air pressure is discharged through the pressure relief cylinder 314, so that the air pressure in the cabinet 1 is maintained within an appropriate range.
[0054] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
