This invention relates to the field of tea leaf winnowing and discloses a reciprocating turbulent winnowing machine for fresh tea leaves. The machine includes a housing with a vertical chamber and a horizontal chamber within it. An inlet is located on the side wall of the vertical chamber, and a centrifugal fan is located at the bottom of the vertical chamber. Both the vertical and horizontal chambers have outlet groups at their bottoms. A cylindrical cavity is formed horizontally within the vertical chamber, and a set of air-distributing plates is rotatably mounted within this cavity. A movable drive structure is connected to the end of the air-distributing plates. The air generated by the centrifugal fan blows some of the fresh tea leaves into the horizontal chamber, where they are discharged through the outlet groups. The remaining fresh tea leaves fall onto the air-distributing plates and are dispersed by the reciprocating rotation of the plates. In this invention, the fresh tea leaves are repeatedly turbulent as the air-distributing plates rotate, which, combined with the airflow, disperses the tea leaf pile, preventing lighter leaves from mixing with heavier leaves and being discharged, thus ensuring the winnowing effect.

The utility model relates to a kind of grain impurity air separator, belong to grain detection technical field, including the air suction collecting pipe, impurity unloader, impurity suction pipe and air separator shell connected in turn, air separator shell is provided with grain discharge port and grain unloading port, the grain discharge port is through with grain unloading port, air inlet is equipped between the grain discharge port and grain unloading port.The utility model device is connected in turn by optimization design, and air suction collecting pipe, impurity unloader, impurity suction pipe and air separator shell form an efficient air separation system.Grain enters air separator shell by grain discharge port, due to the setting of air inlet, so that airflow can be uniformly applied to grain, effectively separate impurities.Outlet is set in the just above of grain unloading port, further improve the air separation effect, ensure that grain is fully air separation treatment before unloading.

The utility model discloses a pepper impurity removal dry cleaning production line, which belongs to the technical field of pepper processing and comprises a bottom plate, the top of the bottom plate is fixedly connected with a support plate, a transmission case and a mounting seat respectively, and the support plate is rotatably connected with an air outlet pipe. The hot pepper winnowing machine is provided with the servo motor, the roller, the winnowing assembly and the transmission assembly, the servo motor drives the winnowing assembly and the roller to work simultaneously through the transmission assembly, the baffles in the roller can continuously turn over hot peppers to enable the hot peppers to be subjected to winnowing more fully in all directions, the winnowing effect is greatly improved, impurity residues are reduced, and compared with traditional equipment, the winnowing efficiency is improved. Impurities in the peppers can be more thoroughly removed, the quality of the peppers is guaranteed, a collecting assembly is arranged, airflow enters a collecting cloth bag in the collecting assembly, the collecting cloth bag can intercept and collect the impurities carried in the airflow, the impurities are prevented from scattering all around, the workshop environment is kept clean and tidy, dust is not diffused any more, the impurities are collected properly, and the environment is protected. Therefore, the purity of the raw materials is ensured.
