[0014] The tobacco cake breaking and stem-leaf separating device will be further described in detail below with reference to the drawings.

[0015] A method and apparatus for breaking up tobacco cakes and separating stems and leaves, such as Figure 1 As shown, it includes a leaf trimmer 1, an air distributor 2, a tangential feeder 3, an air duct 4, a support 5, and a fan 6.

[0016] like Figure 2 The diagram shows a leaf-beating machine 1, which consists of a leaf-beating machine inlet 1-1, a beating roller assembly 1-2, a fixed blade 1-3, a frame 1-4, a power system 1-5, and a leaf-beating machine body 1-6. The power system 1-5 drives the beating roller assembly 1-2 to rotate at high speed. Unloose tobacco cakes are struck by the moving blades mounted on the beating rollers. Under the combined action of the fixed blade 1-3 and the frame 1-4, the tobacco cakes are broken up, and simultaneously, the tobacco leaves on the stems are torn apart and separated from the stems. The beaten material falls through the round hole in the frame 1-4 into the lower conveying pipe 4-1.

[0017] like Figure 3 The diagram shows the air separator 2. A high-speed airflow feeds the processed material into the air separator chamber 2-2 through the feed inlet 2-1. Due to the different suspension velocities of the tobacco flakes and tobacco stems, the flakes, whose suspension velocity is less than the upward airflow velocity, rise with the airflow and enter the tangential distributor 3 through the air outlet 2-3. The tobacco stems, whose suspension velocity is greater than the airflow velocity, sink downwards and enter the tobacco stem collection box through the discharge airlock 2-5. The air separator chamber is equipped with an air regulating plate 2-4. Adjusting the angle and position of the air regulating plate 2-4 ensures that the airflow within the air separator chamber 2-3 meets the velocity and angle requirements. A supplementary air inlet 2-6 is located below the feed inlet 2-1 to prevent tobacco flakes from falling into the windless area at the bottom of the air separator chamber 2-2, thus improving the sorting effect.

[0018] like Figure 4 The diagram shows the distributor 3. The mixture of tobacco flakes and air enters the tangential distributor 3 through the mixing inlet 3-4. Under the combined action of centrifugal force and gravity, the tobacco flakes pass through the outer cavity between the distributor body 3-1 and the distributing screen 3-2, downwards through the discharge air lock 3-3, and enter the tobacco flake collection box. Air enters the blower 6 through the outlet of the tangential distributor 3 and circulates through the air duct 4, providing power to the system.

[0019] Before reaching the leaf-crushing machine, the air duct 4 splits into two paths: the air supply duct 4-1 and the make-up air duct 4-2. The air supply duct 4-1 delivers the crushed material into the air distributor 2, while the make-up air duct provides supplementary air volume to the air distributor 2.
