Continuous bagging processes and systems

摘要

Disclosed herein are processes for continuously bagging pellets. The pellets can be formed from a tacky and/or polymer-containing formulation. Other embodiments relate to systems for continuously bagging pellets. Still other embodiments related the individual components of the processes and systems for continuously bagging pellets.

主权项

1. A system for continuously bagging a tacky and/or polymer-containing formulation, the system comprising:
a feeding section configured to receive a tacky and/or polymer-containing formulation; a mixing section configured to receive the tacky and/or polymer-containing formulation from the feeding section and mix, melt, and/or blend the tacky and/or polymer-containing formulation; a pelletizing section configured to receive the tacky and/or polymer-containing formulation from the mixing section and pelletize the tacky and/or polymer-containing formulation; a drying section configured to receive the tacky and/or polymer-containing formulation from the pelletizing section and dry the pelletized tacky and/or polymer-containing formulation; a pellet diverter valve, with a first position and a second position, to continuously route an incoming flow of pellets comprising:
an inlet configured to receive the incoming flow of pellets from the drying section; andat least a first and second outlet to continuously dispense an outgoing flow of pellets; a controller, in communication with the pellet diverter valve, configured to calculate or receive a first predetermined time interval; and at least a first and second bagging assembly in communication with at least the first and second outlets, respectively, of the pellet diverter valve, wherein the at least the first and second bagging assemblies alternatingly receive a predetermined quantity of pellets from the pellet diverter valve to allow continuous bagging of the pellets; wherein the controller signals the pellet diverter valve to move from the first position to the second position based on the first predetermined time interval.
