What do the different nozzle positions do on the drum cap of the GB-9001?
The Nozzle positions make the area between the drum cap and auger tighter, so at position 3, the pulp would come out more dry and compact due to the tight space between the drum cap and the auger. At position 1, the nozzle would be loose and thus the space between the drum cap and auger would be less tight and the pulp would be looser.
