AI Technical Summary
Existing cooking equipment in microgravity environments suffers from uneven heating, resulting in significant differences in heat absorption in different areas of the food. Some areas are overheated or underheated, affecting the taste and safety of the food.
The upper and lower plates of the cooking equipment are equipped with jet holes, and a guide plate is used to form an airflow circulation path. The guide surface of the guide plate gradually narrows with the surface where the jet holes are located in the direction of airflow, balancing the airflow velocity and air pressure, ensuring that the airflow enters the cooking cavity evenly, and achieving uniform heating of food.
This technology enables food to have a smaller surface temperature difference and more uniform heating in a microgravity environment, thus improving food quality and safety.
