A kneading machine for food doughs includes a kneading bowl, one or more tool shafts rotatably mounted in a housing, a kneading tool attachable to the tool shaft and insertable into the kneading bowl, and a kneading space,each tool shaft being assigned a seal carrier fixed to the housing and which carries a seal arrangement to seal the tool shaft with respect to the seal carrier, the seal carrier being spaced from the tool shaft by a first gap outside the kneading space and which communicates directly with an escape space for food particles escaping out of the kneading space.

A lock member includes a housing, a movement body, and an elastic member. The housing includes an open groove at an inner wall of the housing. A bottom of the open groove is provided with a movement surface. An end of the movement surface proximal to an opening of the open groove is a locking end, and an end of the movement surface distal to the opening of the open groove is an unlocking end. The movement body is provided in the open groove and moveable along the movement surface. The elastic member is provided in the open groove and configured to maintain the movement body at the locking end or the unlocking end of the movement surface.

A dough kneading and feeding system includes a dough barrel that defines a dough handling space in which a screw shaft is provided to extend through a shaft hole and a discharge opening of the dough barrel. An ejection nozzle is coupled with the discharge opening. The screw shaft includes a blade for driving a dough material toward the discharge opening located at the front side to be discharged through the ejection nozzle. At least one assisting screw is arranged, in combination with a bearing, to be parallel with the screw shaft in the dough handling space. The assisting screw includes at least one helical blade, which is rotatable to drive the dough material in a direction opposite to the direction of the dough material driven by the screw shaft and also to drive the dough material toward the screw shaft in a radial direction of the screw shaft.

A baking attachment for a kitchen appliance has an outer container with inner walls enclosing a receiving compartment and an insertion opening on an upper side. A preparation container is arranged in the receiving compartment. A heating device is provided in an intermediate space between a base and side walls of the preparation container and inner walls of outer container. A mixing and kneading mechanism and a cover for the insertion opening are provided. The outer container detachably inserts into a receiving section of the kitchen appliance base. A free end of a rotary shaft of the mixing and kneading mechanism arranged in a connection section has a first coupling section for rotationally fixed connection to a second coupling section on a drive shaft of the kitchen appliance base. Electrical contact elements of the heating device in the connection section detachable connect to electrical contacts of a kitchen appliance base.

A counter-rotating dough making mechanism, including a drive shaft (9) that is provided with an upper dough hook assembly (1) and a lower dough hook assembly (2) is disclosed. The lower dough hook assembly (2) is preferably provided with a stir plate (3) which enhances the thorough mixing of flour during dough kneading. The upper dough hook assembly (1) and the lower dough hook assembly (2) are connected by gears (42a, 42b, 42c) so that they rotate synchronously but in the opposite direction. By the counter-rotating action of the upper dough hook assembly (1) and the lower dough hook assembly (2), the dough making process is more effective as compared to the usual single piece dough hook as used in many stand mixers. The design and construction of the disclosed counter-rotating dough making mechanism is simple, robust, and reliable, and can deliver superior performance in dough making.

A method for manufacturing a food product, comprising mixing dehulled fava bean flour and vegetable protein flour to obtain a basic mixture, wherein the basic mixture has 15-30 wt-% of dehulled fava bean flour and 70-85 wt-% of vegetable protein flour; adding water to the basic mixture in an amount of 30-70 wt-% of the total weight of the basic mixture and water to obtain a hydrated mixture; kneading the hydrated mixture at a temperature of 100-150 C. in an extruder, to form a dough; and allowing the dough to exit the extruder via a cooling die to form the food product, wherein the temperature of the food product at the exit of the cooling die is 50-95 C.

A dough penetration prevention device of a kneading machine includes a lip seal ring having seal ring wings integrally formed on an inner circumferential surface of the lip seal ring and fixed to a bearing housing, a head seal body on the sleeve in front of the bearing housing and fixed by a fixing body, to supply steam at a pressure level equal to the pressure of the kneading container into an opposite gap (t) between an outer circumferential surface of the sleeve and the lip seal ring, in opposition to the steam pressure of the kneading container attempting to penetrate into a gap (t) between the seal ring wings of the lip seal ring and the outer circumferential surface of the sleeve, and a steam supply and discharge part discharging condensed water to the outside while supplying steam to an inner circumferential surface of the head seal body.
