Frequently Asked Questions
Answers to the questions we are asked most, taken from the operator guides. Each answer links to the guide it comes from, where the full explanation lives.
Does press design actually affect rosin quality?
Yes, particularly at the collection step. Pressed rosin is hot, liquefied, and aroma-rich the moment it leaves the plate, so how long it stays on the heat, how much surface it exposes to air and light, and how many times it is handled all shape the finished product. Those variables are set by the equipment's collection architecture.
What is a functionally closed collection path?
It describes a design where the extract discharges through a single drain into a seated collection cylinder, rather than being spread open on a plate and scraped off. Functionally closed does not mean sealed or airtight (the drain is still open to room air), but it presents far less exposed surface and far fewer open handling steps than an open flat-plate press.
How do the Flow Control bags relate to the collection path?
The truncated-cone Flow Control mesh bag and its O-ring flow seal are components of the same geometry: they direct the mobilized resin down the cone toward the central drain instead of letting it spread. The bag, the cone plates, and the front collection cylinder work as one system. See the bag as a flow-control device for how its geometry sets flow, and the pre-folded parchment pouch for the final stage. To match a bag to your platen, browse the rosin filter bags.
Which presses use this collection architecture?
The cone-plate, central-drain, seated-cylinder design is the basis of the Access Rosin press line: the FLUID, AIR, and KWÄD, paired with Flow Control filter bags. See the presses.
Is a rosin bag just a micron rating?
No. Micron sets the mesh permeability, but the bag's construction (where the seams sit, whether the base tapers, whether folds or flaps trap resin) sets the flow area and path length just as much. Two bags at the same micron can flow very differently under load. See the V3.7 rosin bags.
Why do rosin bags blow out?
A blowout is usually a flow-path problem, not simply too much pressure. When flow is choked by a bottom seam across the exhaust path, or by a tapered base collapsing and closing channels, pressure builds inside the bag until a seam fails. Keeping defined channels open under load is how the V3.7 geometry is designed to relieve that pressure.
Why pre-folded parchment instead of folding a sheet by hand?
Because hand-folding can't reproduce the same geometry twice. The pre-folded pouch has engineered cut lines that roll and interlock into a self-fixturing shape sized to the press, so the correct flow channel and placement are the default outcome rather than something you measure out under pressure. See the parchment formats.
Does parchment do anything besides keep rosin off the plates?
Yes, three jobs at once. It's a release surface (keeps extract off the metal), a flow conduit (a walled tunnel that speeds the extract to a single exit), and a positioning fixture (centers the bag and puck so every pouch points at the drain). The shape does as much work as the coating.
