Combi steamers (also called combi-steamers, hot-air steamers, combination steam-convection ovens, or simply combi ovens) are cooking appliances typically used in professional catering or food service operations. Combi steamers can produce both dry (convection) and moist (steam) heat, and are capable of shifting between them automatically during the cooking process. It can be used to simultaneously steam vegetables or potatoes quickly and gently, while also roasting or braising meat and fish, or baking bread. The appliance is fit for many culinary applications, including baking, roasting, grilling, steaming, braising, blanching and poaching. Combi steamers expand upon standard convection ovens in that they also generate steam or a combination of steam and superheated steam. They help gastronomy-industry professionals bridge the gap between economy and menu diversity while also maintaining the desired food quality. https://www.youtube.com/watch?v=Ya6xwlR8phg& amp;t=33s
