The invention discloses a gap-type high-pressure boiling device for seed nut food. The gap-type high-pressure boiling device for seed nut food comprise a rack, a rotary power mechanism A, a top lift cylinder, a lifting arm, a rotary power mechanism B, a top cover rotating shaft, a top cover, a boiling pot body and a mesh material barrel, the top of the rack is mounted with the rotating power mechanism A through a bracket, a driving gear A is mounted on the rotating power mechanism A, and a driven gear A is mounted on the top lift cylinder; the lifting arm is fixed on the top of a lifting rod of the top lift cylinder, the rotary power mechanism B is mounted on the lifting arm, the driving gear A is mounted on the rotary power mechanism B, the top cover rotating shaft is rotatably mounted onthe lifting arm, and a driven gear B is mounted on the top end of the top cover rotating shaft, the boiling pot body is arranged on an electric heating seat, and the mesh material barrel is arrangedinside the boiling pot body. The device carries out high-pressure boiling treatment on the seed nut snack food, and solves the problems that the seed kernel is difficult to taste, the shell is difficult to remove, the energy consumption is high, the baking time is long, and the efficiency is low.
