A short-waveband active optical component based on a vertical emitting laser and a multi-mode optical fiber has an emitting end and a receiving end. In the emitting end, multiple VCSELs generate multiple optical signals of different wavelengths, and multiple photodiodes in the receiving end receive the optical signals emitted by the VCSELs. Both ends use a focusing lens array to collimate and focus the optical signals A Z-block-shaped prism performs a light combining function at the emitting end, while another Z-block-shaped prism performs a light splitting function at the receiving end. Both ends use a focusing lens for collimating and focusing the optical signals at ends of a multi-mode optical fiber, which is used for transmitting the optical signals generated by the VCSELs. The short-waveband active optical component has a small size and a high transmission rate.

The invention relates to a tobacco shred feeding treatment device and a method for improving the heat energy and feed liquid absorption efficiency of tobacco shred, comprising: a tobacco shred feeding machine, said tobacco shred feeding machine mainly comprises a roller, a process warm-air pipe, a power blower, a heater, a steam nozzle, a feed liquid nozzle and an air inlet pipe; the process warm-air is blown into said roller from said air inlet pipe via said steam nozzle and said heater under the action of said power blower, and mixed with the tobacco shred; said air inlet pipe is provided directly under the central axis of said roller; the opening of said air inlet pipe faces up obliquely, and the opening direction of which could be adjusted into any position within the roller according to the requirements; said steam nozzle is mounted between the power blower and the heater, to achieve heating the condensed water in the steam, and to avoid directly injecting the steam to burn the tobacco shred. Under the premise that it is not necessary to configure the tunnel heating and humidifying equipment, the process warm-air with steam can contact with the tobacco shred sufficiently to improve the heat energy and feed liquid absorption efficiency and uniformity.
