  • Patent number: 5947009
    Abstract: An automatic baking apparatus for baking food products from dough having upper and lower holding devices (14, 16, 76) to be affixed to either end of a flexible, sealable mixbag (44) which mixbag contains ingredients for dough. A dough preparation and baking station (24) having a slit (37, 41) at the top and bottom portions. Kneading devices (22, 24, 39, 43, 56) for mechanically working the ingredients in the mixbag. Devices for creating relative reciprocating movement between the mixbag and the slit openings and heating means (18, 20) in at least a portion of the dough preparation and baking station 25 so as to bake the kneaded ingredients. The kneading devices situated in the top and bottom portions of the apparatus, the top and bottom slits (37, 41) are each formed by a set of two adjacent members (22, 24, 39, 43, 56). Each member has a kneading surface (36, 38, 40, 42) defining the slit between each set and through which slit the mixbag passes.

  • Patent number: 5146840
    Abstract: An automatic baking apparatus for making food products in piece form from dough-like substances which apparatus has holding means adapted to be fixed to the top and bottom edges of a flexible sealable mixbag (100) containing dry ingredients and water. The baking apparatus has upper and lower drums (230,232) and means for moving the drums, and the mixbag has male protrusions (134, 134a) at the upper and lower edges so that the mixbag (100) can be attached respectively to the upper and lower drums (230, 232). The holding means on the upper and lower drums is in the form of a female groove (234, 234a) commensurate in shape with the male protrusions (134, 134a) on the mixbag so that the mixbag male protrusions can be detachably interlocked with the female grooves on the drums. In this way the mixbag is attached to the drums for a kneading process in the baking apparatus and after the kneading process is completed, the mixbag is rolled up onto the lower drum (232).
