Abstract
Abstract The lid support member for the lid of a high speed food processing apparatus supports a mixing baffle blade through the center of the lid. The mixing baffle blade and its rotatable support are counterbalanced to help prevent the mixing baffle blade from freely rotating when its axis of rotation is not vertical.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
In an apparatus for processing foodstuffs, including a mixing bowl having a drive shaft extending into the bowl through the bottom thereof, a motor mounted outside the bowl and connected to rotate the drive shaft, food processing blades mountable on the drive shaft within the bowl for processing foodstuffs therein when the motor is operated, a cover system including a lid for closing the top of the bowl, a mixing baffle blade and support mounted in the lid for rotation along and around the inside surface of the bowl for removing and returning foodstuffs from the side of the bowl to the vicinity of the food processing blades for further processing thereby, and a handle system including a handle outside the lid and means operatively connecting the handle to the mixing baffle blade support to rotate the support and mixing baffle blade, the improvement comprising balance means including the handle system being sized and positioned for counterbalancing the mixing baffle blade and the mixing baffle blade support when the axis of rotation thereof is not vertical.
