The invention discloses a pneumatic extrusion type deblocking machine for tea. The pneumatic extrusion type deblocking machine comprises a case; the top end of the case is provided with a hopper; the interior left and right sides of an inner barrel are respectively provided with a left platen and a right platen; the left platen and the right platen are both connected with the inner barrel via vibration springs; the outer side of a hollow metal plate is provided with tooth cones; through holes are formed in the tooth cones; and the outer sides of the through holes are provided with gas-jet heads. According to the pneumatic extrusion type deblocking machine provided by the invention, a vibration exciter works and transmits vibration force to the right platen under the cooperation among the right platen, the tooth cones and the gas-jet heads, and the right platen is cooperated with the left platen during vibration so as to realize extrusion deblocking of tea; during vibration of the right platen, tea blocks are pushed and pressed by the tooth cones, so tea deblocking effect is improved; jet gas is used for blowing and deblocking of tea, so tea deblocking effect is further improved; and the pneumatic extrusion type deblocking machine is diversified in deblocking procedures and improved in deblocking effect and meets demands of tea processing.
