  "description_excerpt": "This application is a continuation of U.S. application Ser. No. 13/770,081 filed Feb. 19, 2013 entitled “Scalable Automated Cooking System Having Small Footprint and Reduced Labor Cost,” the disclosure of which are hereby incorporated herein by reference in their entireties.\n\nUS Patent Applications:\n\nSer. No. 13/770,081, Filed: Feb. 19, 2013, Inventor: Zhengxu He\n\nSer. No. 13/607,712, Filed: Sep. 8, 2012, Inventor: Zhengxu He\n\nSer. No. 13/490,523, Filed Jun. 7, 2012, Inventor: Zhengxu He\n\nThe present application relates to cooking system, and specifically to cooking method and equipment capable of automatically delivering food ingredients.\n\nConsiderable amount of research and experiments have been conducted on automating cooking. A conventional cook apparatus includes a full set of storage containers positioned above each cooking container. A drawback of conventional cook apparatus is it requires too many storage containers for each cooking container, which takes too much space in a kitchen. For example, a kitchen in a common fast food restaurant may include dozens of storage containers. The problem becomes even worse when there are multiple cooking containers in a kitchen; the kitchen must have large space to host such systems with multi-cooking containers. In addition, subdividing a same ingredient into more than one storage containers disallows sharing by different cooking containers.\n\nU.S. Pat. No. 4,919,950 teaches an automated cooking system comprising a plurality of cooking containers and a conveyor means for moving the cooking containers along a pre-determined path, as to access the dispensers of food ingredients.",
