Right: The AK400 strand dryer from Accrapak is suitable for 40-60 strand production
Steven Critchley. “We have now added a small suction dryer to our production range. Our AK50 will dry up to seven strands of extruded polymer ensuring a dry cut when strand pelletising.” The dryer can be used on seven-strand lines at a rate of up to 200kg/h. Further up the scale, the company has also developed a larger machine for production lines running at between 1-2 tonnes/h. The AK400 can handle 60 strands at 3mm diameter and features a feed width of 400mm and a powerful centrifugal fan, according to Critchley. Existing suction dryers – the AK100, AK200, and AK300 – are benefiting from the new developments, too. “When
designing our new suction dryers we have also incorporated the new features throughout the range,” Critchley says. These include a redesigned drying chamber with a longer suction head, giving strands more time in the drying chamber. “The extra slot ensures more suction hits before being fed into the strand pelletiser, Critchley says. The suction head has been pressure tested to obtain the maximum amount of suction vacuum for each machine and extra suction slots have been added to obtain the maximum amount of hits, ensuring the best possible drying of each extruded strand. The slots are adjusted to give the maximum
possible airflow through the suction plate, which is then locked into position with the correct suction slot gap for each individual machine.
All the machines are now
also fitted with an inverter drive as standard to run the fan
at 60Hz, which provides 20% more suction, while the adapter between the filling head and the suction tube is now conical provide maximum air flow. In addition, the fan unit orientation has been modified to allow optimise the exhaust, further increasing suction power. “We estimate that the modifications have increased the suction power
throughout the range by more than 25% to an already proven design,” Critchley says. “We
are now in the process of designing a new model which recirculates the air flow from the suction head back into the drying chamber. This will blow air down onto the extruded strands as they pass over the suction plate without blowing water into the working area.”
