Final answer:
A pressure steamer cooks food at higher temperatures by sealing the chamber and building pressure, leading to faster cooking times,
Step-by-step explanation:
The main difference between a pressure steamer and a convection steamer is the way they use steam to cook food. A pressure steamer, similar to a pressure cooker, seals the cooking chamber, allowing the pressure to build up, which raises the boiling point of water and cooks food at a higher temperature.
This process results in faster cooking times because the higher temperature accelerates the cooking process. On the other hand, convection steamers use steam as well, but do not seal the chamber. Instead, they cook by continuously bringing hot steam into contact with the food, often circulating the steam around the food to cook it evenly.
While convection steamers provide more even cooking and can cook large batches of food, they do not operate at the higher pressures and temperatures that pressure steamers do, and thus may take longer to cook the food.
while a convection steamer circulates steam around the food for even cooking but does not use increased pressure.
