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 steaming cabinet refers to a large kitchen baking device that uses electricity or gas to heat and steam rice. A stainless steel steaming plate (stainless steel square plate) is used as a container inside. In order to facilitate movement, universal wheels are installed under the device, so the appearance is like a car. The body is cabinet-shaped and made of stainless steel, generally 304 stainless steel. Rice steaming carts are mostly used in large canteens such as hotels, troops, 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 intake 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 intake 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 hinged on 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 intake 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, which improves efficiency and safety while being conducive to electrical dual use, high adaptability, and convenient control and use.

[0004] When the above-mentioned existing plateau rice steaming cabinet is in use, the rice to be steamed is placed in the rice steaming cabinet, 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 steaming cabinet, which will cause the air pressure in the rice steaming cabinet to increase to a suitable pressure for a longer time. At the same time, the steam in the rice steaming cabinet is from bottom to top, and the temperature received by the rice on the top layer is lower than that on 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 steaming cabinet is provided. Summary of the invention

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 storage 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 storage 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 with a placement rack 205, and a plurality of heating grooves 206 are slidably connected on the inner wall of the placement rack 205.

The connecting valve 216 is a prior art and will not be described in detail herein. 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 storage tank 202. 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. 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 a plurality of rods. A reflux pipe 303 is arranged at the lower end of the reflux rack 302. The reflux pipe 303 is on 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 from the top rice, resulting in excessive moisture in the top rice. See also Figures 1 to 8 A detection cylinder 304 for detecting the pressure is fixedly installed on the inner wall of the installation box 301, a piston ring 305 is slidably installed on the inner wall of the detection cylinder 304, and a telescopic spring 306 is fixedly installed 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, and the calculation formula is: F=P×A F represents the thrust Newton of the gas pressure in the cabinet 1 , N, P represents the pressure of the gas in the cabinet 1 in Pascal, Pa, and A represents the effective working area of ​​the piston ring 305 .

[0022] When the piston moves, the piston squeezes the telescopic spring 306. The formula for calculating the force of the telescopic spring 306 is: F=kx F represents the elastic force of the spring, and the unit is usually Newton N. k represents the elastic coefficient of the spring, also known as the stiffness coefficient or spring constant, with the unit of Newton per meter N / m. It describes the elastic properties of the spring material and is a characteristic parameter of the spring.

[0023] x represents the deformation of the spring, that is, the distance the spring is compressed or stretched.

[0024] Thus, the air pressure in the cabinet 1 can be calculated by the above calculation formula.

[0025] 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 , and an insulating sleeve 309 is provided on one end of the resistance rod 308 close to the linkage rod 307 .

[0026] See also Figures 1 to 8 A current-carrying coil 310 is fixedly installed at the upper end of the installation box 301 near the resistance rod 308, a transmission line 311 is fixedly installed at the side end of the current-carrying coil 310, and an air pressure pump 312 is fixedly installed at the end of the transmission line 311 away from the current-carrying coil 310. Specifically, when the current-carrying coil 310 moves to the outer surface of the insulating sleeve 309, the air pressure pump 312 no longer works. When the current-carrying 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, and the filter prevents debris in the air from being transmitted to the installation box 301 through the air pressure pump 312.

[0027] See also Figures 1 to 8 A pressure relief pipe 313 is fixedly installed on the upper end of the installation box 301 near the resistance rod 308, and a pressure relief cylinder 314 is threadedly installed on the upper end of the pressure relief pipe 313, and an exhaust groove for pressure relief is opened at the upper end of the pressure relief cylinder 314, and an air pressure scale rod 315 is set on the upper end of the installation box 301 near the pressure relief cylinder 314. The air pressure scale rod 315 at the upper end of the installation box 301 makes it more convenient for the staff to rotate and adjust the height position of the pressure relief cylinder 314 to a suitable height. An exhaust piston 316 is slidably installed on the inner wall of the pressure relief cylinder 314, and the resistance rod 308 is rotatably connected to the lower end of the exhaust piston 316. When the air pressure in the cabinet 1 is greater than the normal range, 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 a suitable range.

[0028] The working principle of the present invention is as follows: when the rice steaming cabinet is used, 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 to work 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 size; 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, and the heating pipes 208 in the plurality of heating tanks 206 start to work, evaporating the water in the heating tanks 206 to generate water vapor, heating and steaming the materials on the placement rack 205, so that the food is heated more evenly; 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 a suitable range.
