The invention discloses a static-pressure fried dough twist machine with a pneumatic suspended cylinder, and relates to the field of food processing machinery. The static-pressure fried dough twist machine is characterized in that a transverse beam support frame is arranged on the upper side of the edge of a bottom plate, a dough vat is arranged in the middle of the bottom plate, an upper transverse beam is arranged on the upper side of the transverse beam support frame, a supporting seat is arranged on the lower side of the middle of the upper transverse beam, the cylinder is arranged below the supporting seat, a rotary disc connecting rod is arranged below the cylinder, a rotary pressure disc is arranged below the rotary disc connecting rod, a large belt pulley is arranged on the outside of the dough vat and is connected with a motor by a belt, a dough passing pipe is arranged below the dough vat, an internal gear is connected to the lower side of the dough passing pipe, a forming hopper is connected to the lower side of the internal gear, and a dough discharge forming sheet is arranged at a lower port of the dough passing pipe. The static-pressure fried tough twist machine has the advantages that destruction to glutinous degrees of dough for fried dough twist can be prevented, and products can be prevented from being contaminated.
