Reconstituted Tobacco Sheet Processing Equipment By Rolling

Reconstituted Tobacco Sheet Production Line By Rolling

1. General Statement

Reconstituted Tobacco Sheet Production Line By Rolling is one complete group of equipment which makes full use of tobacco waste such as tobacco stems, powder and dust etc. produced in cigarette manufacturing process. It adopts special technical recipe and flow to finally remake the waste into tobacco Sheet filament.

This production line has the advantages of small investment, environment protection without pollution during manufacturing, reducing cigarette production cost greatly and producing great economic profit.

The production capability of it has specifications of 80kg/h, 180kg/h, 200kg/h, 400kg/h, 600kg/h, 800kg/h.

4.2 The main characteristics of Recon Production Line:

 (1) Pre-treatment section adopts the working procedures of vibratory sieving, iron removing and pneumatic classification, to effectively eliminate the impurity of the raw material so as to raise the purity of the materials.

 (2) The tobacco stem and powder adopts time-sharing drying on line and automatic classification storage. The stem and powder are proportioned automatically under the accurate control of screw electric scale with its error less than 2%. What’s more, it is convenient to adjust the proportion between the tobacco stem and powder. The drying of tobacco stem and power adopts the drying cylinder with dehydration capacity is more than 6%. After drying, the material has moisture of not more than 10%, which is easy to be grinded.

 (3)The material pneumatic conveying system and grinded material pneumatic conveying system both adopt negative pressure operation, two-stage dust discharging, which improves the environment of workshop.

 (4) Stem bin and powder bin both have been installed with material positioning sensor, which achieves an automatic start/stop of equipment through the signal interlocking.

 (5) The measuring of liquid and solid material all adopt decrement electronic scales .It can control the accuracy of materials output through frequency conversion control. It can ensure the moisture accuracy ±2% after blending.

 (6) It adopts advanced technology in stem defibration. The tensile strength of recon will raise over 100% after adding stem fiber. It raises greatly the valid utilization rate of the sheet which is ≥95%.

 (7) The adoption of the second time crimping technology can raise the filling value of cut-recon. After the drying & crimping cylinder, there is a cooling de
