The invention relates to a process and to a device for producing a pore-containing foodstuff, the matrix of which enclosing the pores contains starch. The process is characterized in that the dough is flowable, is admixed with pressure gas and is expanded through a nozzle into an adjacent flow-through channel so that the raw dough containing pressure gas foams in the flow-through channel. For warming of the foamed dough the flow-through channel has a section which is directly adjacent and has at least two electrodes arranged on its circumference for applying current to the foamed dough.

A dough preparation machine includes a power unit, which drives, through rotational speed mechanism, a helical screw shaft that extends into a dough chamber so that the dough is compressed and pushed through rotation of the helical screw shaft to be discharged out of a jet nozzle mounted to the dough chamber. The dough chamber is provided, at a location above the helical screw shaft, with an auxiliary dough driver, which includes two movable blades that are opposite to each other and are selectively extendable outward and retractable inward. When one of the movable blades passes through a circular sidewall of dough chamber, it is pressed by the sidewall to get retracted inwardly and at the same time causing another one of the movable blades to extend outward to knead and poke dough. This process is cyclically repeated to efficiently knead the dough and prevent attachment of the dough.

A device for preparing extrudable food products includes a working chamber configured to house ingredients in operation of the device, an extrusion die, a rotation shaft configured to stir the ingredients and extrude the food products through the extrusion die, and a driving system by which the rotation shaft is driven. The driving system is configured to separate the extrusion by at least one time period during which the rotation shaft rotates in a first direction which is opposite to a second direction in which the rotation shaft rotates to extrude the food products. Therefore, build-ups inside the working chamber can be removed by the sticky dough hit and/or lifted by the stirring bars on the rotation shaft when the rotation shaft rotates reversely.

A dough-based food product, an apparatus and method for production of the dough-based food product. A food product matrix to be foamed includes a proportion by weight of a starch-containing raw material and a proportion by weight of water. Gas that has been dissolved or is to be dissolved is introduced into the food product matrix to be foamed. The gas is dissolved under pressure in the food product matrix to be foamed. Gas bubbles are formed by expansion and increasing the volume with a resulting reduction in density of the dough as a result of bubble growth for formation of a foamed food product matrix of the food product to be produced. The foam is then stabilized. Gas is introduced into and dissolved in the aqueous component of the food product matrix to be foamed in a subcritical state below the critical point and at a pressure of 10 barp<critical pressure of the gas.

A vertical household noodle maker includes a base, a stirring container connected to the base, a stirring rod longitudinally arranged in the stirring container, an extrusion cylinder horizontally arranged at one side below the stirring container, a spiral rod arranged in the extrusion cylinder, an extrusion die and a control unit. The stirring rod includes a rod body and a stirring blade. The motor rotates the stirring rod and the spiral rod, and a feeding inlet in communication with the extrusion cylinder is provided at a bottom of the stirring container. An inner wall of the stirring container is provided with a cutting rod, and a projection of the cutting rod at least partially overlaps with a projection of the stirring blade in the horizontal direction when the stirring blade is driven by the motor to rotate to a position of the cutting rod.
