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 below 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 press 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 end 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 cannot be contaminated.
