The patented Torresak vacuum sealer/N2 purge machine was carefully designed to meet challenges unique to biochar packaging in mind. There are two modules attached to arms than swing in and out as needed for filling and vacuum sealing/N2 purging the patented, hermetically lined bulk FIBC bags. A box shaped vibratory compaction table with adjustable frequency removes airspace between biochar particles, and enables 20% more material to be loaded into the bag. The extra- long, extra -wide fill spout attaches securely to filling tube, and a plumbing fixture on the tube enables N2 gas to be added into the bag during the filling cycle. This “nitrogen blanket” extinguishes any live biochar embers that may enter into the bag while filling product.

Once the bag has been filled, the filling module is detached from the bag filling spout, and swung out of the way. Then, the vacuum sealing module is swung in and attached to the spout opening. Using a simple shop vacuum, air is quickly removed from inside the bag. The patented vacuum nozzle features an expansion chamber, which slows down the velocity of the air being removed from the Torresak bag. The velocity of air being evacuated through the nozzle is lower than the settling velocity of dust, so that no biochar fines are removed from the bag. Tubes inside the entry aperture of the nozzle prevents the bag spout from collapsing and blocking air flow during evacuation. The vacuum sealing/N2 purge process normally takes less than 5 minutes.

Torresak packaging equipment are very well made and durable, and should provide decades of service.
