Patent number: 5878655Abstract: An automatic convection heating baking apparatus for bread or cake making with greatly improved automatic-baking quality is disclosed. Baking in this apparatus is achieved by two hot air streams each covering about half of the baking chamber space. Hot air circulation is produced by forming suction and blowing regions within the baking chamber by placing an electric fan within a single ventilation compartment. The machine is compact and low-cost since only a single electric fun is needed to cause circulation and to produce two hot air streams, premature hot air return to the ventilation compartment is prevented by using air-regulating means. Dual timer for mixing and baking is provided to improve cake fluffiness by controlling heating during ingredient mixing.Type: GrantFiled: November 18, 1996Date of Patent: March 9, 1999Assignee: China Packific Trade Ltd.Inventor: Wing Kin Chan
