[Sticky] CUP15 Gen 2.0 - Basic SOP for cold temp process
CUP15 Gen 2.0 - Basic SOP for cold temp process
- DO NOT OPERATE SYSTEM INSIDE OF FREEZER
- DO NOT PUT DRY ICE INSIDE SOLVENT FOR OPERATION
- DO NOT RUN SYSTEM BELOW -40c (PSI review cleared to -40c. Hoses and auxiliary equipment is NOT rated below -40c)
- DO NOT RUN SYSTEM ABOVE +60c
- DO NOT OVER-PACK MATERIAL BAGS (10 lbs for gen1.2 / 15 lbs for gen2.0)
- DO NOT RUN LIQUID NITROGEN OR CO2 IN SYSTEM JACKET
- DO NOT APPLY VACUUM TO CUP SYSTEM
- DO NOT APPLY PRESSURE TO CUP SYSTEM
- DO NOT OPERATE ON AN UNEVEN SURFACE
Operator loads material bags with 8-14 pounds of biomass (dependent on type of biomass and milling of material).
The bag must have biomass filled in an even distribution, the operator will want to press the material down into the bag every few inches with a medium force to fill it up evenly without damaging the bag. Once the bag is packed, the operator will load the the bag into the system and then pack it down into the CUP chamber evenly (an even distribution of biomass will provide best results).
- Operator closes the lid & makes sure the drain valve is closed.
- Operator loads alcohol into system from alcohol-source kegs. There are two options for doing this:
First Option: Alcohol is pushed out of the source keg using compressed nitrogen (with regulator) into the CUP chamber. Use no more than 15 psi for this procedure. The operator needs to make sure when filling starts that the system has both ball valves open to allow air displacement while the system is filling with solvent.
Secondary Option: Alcohol is transferred out of the source keg using a pneumatic transfer pump, powered by either: a remote air compressor, or inert compressed gas. The operator needs to make sure when filling starts that the system has both ball valves open to allow air displacement while the system is filling with solvent.
- Once the system is full of alcohol, operator starts the agitation process.
On the system control panel click "Agitation 1". The operator can program the RPM & the duration of the agitation. Most processes will run the agitation between 85-130 rpm. Once the operator has entered the parameters, click "START" to begin the "Agitation 1" program. The plant material/alcohol will then undergo a bi-directional agitation sequence. The duration of the agitation sequence when doing a room temp. extraction is roughly 5-10 mins per load. The colder the system is, the longer the agitation sequence can be run before extracting undesirable compounds. When running cold it can be beneficial to use a chiller on the jacket or to pull a vacuum to help with thermal degradation. Using an injection coil from the keg to the system can also help with keeping the alcohol stay at a constant low temp in between programs, which is important to avoid pulling the chlorophyll and waxes.
- OPERATOR NEEDS TO MAKE SURE IF THE KEG WAS PRESSURIZED TO FILL THE SYSTEM THAT THE PRESSURE IS RELEASED BEFORE THE DRAIN BEGINS.
- When the "Agitation 1" program is complete, operator opens the drain valve to start draining the fluid out of the system into an empty storage keg.
Once the system has drained most of the alcohol (minimal amounts of flow will be visible through sight-glass) the operator will start the "Spin" mode to extract the residual tincture from the biomass. On the control panel click "Spin 1". The CUP15 2.0 system comes preset with a 6 min spin out time. It starts at 250 RPM for then ramps up to 1800 RPM for 5 minutes.
- Upon completion of the spin mode, operator unlocks the lid and pulls the material bag out of the system.
It will be dry to touch and won't be dripping any alcohol - However, it still has 2-3 percent residual solvent inside of the biomass. Operator should place spent material in a well ventilated room or under a fume-hood to off gas the remaining alcohol before disposing of the biomass.
The process can be repeated until a maximum saturation of desirable compounds has been achieved.
This method provides the safest, most economically viable way to batch-process biomass using alcohol. Typically, on medium-quality input material, clients are doing 3-4 loads (typically 30 lbs of alcohol per keg) - On high-quality input material, clients are doing 2-3 loads (20-24 lbs of alcohol per keg).
