Tobacco shred expansion equipment and tobacco production system

The utility model provides cut tobacco expansion equipment and a tobacco production system. The tobacco shred expansion equipment comprises a storage bin used for storing tobacco shred flowing out of a steeper; the expansion device is arranged on the downstream of the storage bin in the flowing direction of the tobacco shreds so as to receive the tobacco shreds flowing out of the storage bin and enable the tobacco shreds to expand; and the loosening device is arranged between the storage bin and the expansion device along the flowing direction of the tobacco shreds and is used for loosening the tobacco shreds flowing from the storage bin to the expansion device. Therefore, the expansion effect of the tobacco shred expansion equipment can be effectively improved. 本申请提供一种烟丝膨胀设备和烟草生产系统。烟丝膨胀设备包括：贮存仓，用于贮存从浸渍器流出的烟丝；膨胀装置，沿着烟丝的流转方向设置于贮存仓的下游，以接收从贮存仓流出的烟丝，并使烟丝膨胀；和松散装置，沿着烟丝的流转方向设置于贮存仓和膨胀装置之间，并对由贮存仓流向膨胀装置的烟丝进行松散。这样，可有效改善烟丝膨胀设备的膨胀效果。
