AI Technical Summary
At high altitudes, boiling and steaming food at normal pressure lowers the temperature, resulting in undercooked food. Pressure cookers, on the other hand, cause excessively high temperatures, leading to poor cooking quality, nutrient loss, and unpleasant taste in noodle and steamed rice dishes.
A high-altitude steaming pot was designed. By adjusting the pressure inside the pot using a low-pressure relief valve, the food status can be monitored in real time through an observation window. A water inlet valve adds cooling water to increase the elasticity of the noodles, and an exhaust valve quickly releases pressure to prevent the noodles from becoming soft, thus achieving efficient cooking.
High-altitude cooking is achieved, preventing excessively high or low temperatures, preserving the nutrition and texture of food, avoiding softening of pasta, and improving food quality.

Abstract
Claims
1. A high-altitude cooking pot, comprising a pressure cooker body (1), a pressure cooker lid (2) screwed onto the pressure cooker body (1), a pot handle (11) and a lid handle (21) fixedly installed on the same side of the pressure cooker body (1) and the pressure cooker lid (2), an exhaust port (22) disposed at the center of the pressure cooker lid (2), a safety valve (23) and a float valve (24) fixedly installed on the pressure cooker lid (2), and a steaming rack (12) disposed inside the pressure cooker body (1), characterized in that: A low-pressure relief valve (221) with an adjustable range of 0.015-0.2 MPa is fixedly installed on the exhaust port (22). An observation window (3) for observing the internal condition of the pressure cooker body (1) is fixedly installed on the pressure cooker lid (2). A water inlet valve (4) for adding a small amount of cooling water twice when cooking noodles to increase the elasticity of the noodles is fixedly installed on the pressure cooker lid (2). An exhaust valve (5) for quickly releasing pressure to prevent the noodles from becoming mushy and soft is fixedly installed on the pressure cooker lid (2).
2. The high latitude digester of claim 1, wherein: The pressure cooker lid (2) is provided with a first mounting hole (25), a second mounting hole (26) and a third mounting hole (27) for installing the water inlet valve (4), the exhaust valve (5) and the observation window (3), respectively.
3. The high latitude digester of claim 2, wherein: The observation window (3) includes a well pipe (31) inserted into the top of the third mounting hole (27), a limiting ring (311) fixedly connected to the side of the well pipe (31), a locking ring (32) screwed to the bottom of the well pipe (31) and in contact with the bottom surface of the pressure cooker lid (2) so that the limiting ring (311) abuts against the top surface of the pressure cooker lid (2), and a windowed cover (33) installed at the top of the well pipe (31) by a flange connection.
4. The high latitude digester of claim 3, wherein: The bottom end of the first mounting hole (25) is connected to a first hollow bolt (41) that is screwed to the bottom end of the water inlet valve (4) for locking the water inlet valve (4) on the pressure cooker lid (2).
5. The high latitude digester of claim 4, wherein: The bottom end of the second mounting hole (26) is connected to a second hollow bolt (51) that is screwed to the bottom end of the exhaust valve (5) for locking the exhaust valve (5) on the pressure cooker lid (2).
6. The high latitude digester of claim 5, wherein: The bottom end of the exhaust port (22) is connected to a third hollow bolt (222) that is screwed to the bottom end of the low pressure relief valve (221) to lock the low pressure relief valve (221) on the pressure cooker lid (2). The low pressure relief valve (221) is fitted with a steam cover (6) that surrounds the side of the low pressure relief valve (221) to collect the leaked steam and hold it in water.
7. The high latitude digester of claim 6, wherein: Sealing gaskets (7) are provided at both the upper and lower ends of the first mounting hole (25), the second mounting hole (26), the third mounting hole (27), and the exhaust port (22). The sealing gaskets (7) are polytetrafluoroethylene gaskets.
8. The high latitude digester of claim 7, wherein: A sealing gasket (7) is also provided between the top of the windowed cap (33) and the top of the well pipe (31).
