Equipment Gap Matrix — Cannabis to Kratom Powder
Authority: 01-RFP-RESPONSE.md Section 1
Benchmarks: 08-BENCHMARK-RESEARCH/
1. Reference: cannabis flour / dry milling line
Typical unit operations for cannabis or hemp flour / powder / biomass milling (not extraction):
| Step | Equipment | QC checkpoint |
|---|---|---|
| Receiving | Dock, pallet jack, scale | COA review, identity, moisture |
| Quarantine | Segregated hold area | Lot hold until release |
| Cleaning | Vibratory screener, destoner, magnet | Foreign material |
| Conditioning | Dampener / dryer (optional) | Moisture % target |
| Size reduction | Hammer mill, pin mill, roller mill | Particle size distribution |
| Classification | Plansifter, vibratory screen | Mesh target (product-specific) |
| Blending | Ribbon blender, tumble blender | Homogeneity |
| Packaging | Auger filler, checkweigher, sealer | Fill weight, seal integrity |
| Metal detection | Inline magnet / metal detector | Foreign metal |
| Utilities | Bucket elevator, pneumatic convey, dust collector | CFM, filter ΔP |
| Safety | Explosion venting, spark detection (NFPA 652) | Combustible dust program |
Cannabis-specific overlays: METRC tag assignment, potency sampling (THC/CBD), state-mandated microbial limits (where applicable), child-resistant packaging (retail cannabis).
2. Reference: extraction stack (Black Rock pipeline overlay)
Parallel path common in conversion targets — not required for powder-only kratom:
| Step | Equipment | Notes |
|---|---|---|
| Extraction | CO2, hydrocarbon closed-loop, ethanol | C1D1/C1D2 rooms |
| Filtration / dewax | Filter media, inline dewax | Cold ethanol |
| Concentration | Rotary evaporator, falling film | Solvent recovery |
| Distillation | Short-path / wiped film | Potency concentration |
| Remediation | Chromatography (some labs) | THC remediation (hemp) |
| Formulation | Vape fill, emulsification | Finished cannabis SKUs |
Pivot implication: Extraction CapEx is relevant for extract/tincture kratom SKUs or idle until Scenario A frees the room for powder line expansion.
3. Target: high-volume kratom powder line (AKA GMP aligned)
| Step | Equipment | QC checkpoint |
|---|---|---|
| Supplier qualification | Vendor files, audit records | Approved supplier list |
| Receiving | Import docs, scale, quarantine | Identity, COA review |
| Kill step | Steam pasteurization tunnel, batch oven, or validated alternative | Micro reduction study |
| Pre-grind | Coarse mill | Throughput |
| Fine mill | Pin/hammer mill | 40–80 mesh typical retail |
| Blend | Ribbon / tumble blender | Representative sample |
| Sieve | Vibratory classifier | Overs removal |
| Metal detect | Inline detector | Reject log |
| Pack / label | Auger fill, batch coder, QR COA | Label accuracy, 21+ |
| Release | QCU sign-off | ISO 17025 third-party COA |
Required COA panel (category baseline): mitragynine, 7-hydroxymitragynine (where required), Salmonella, E. coli, yeast/mold, heavy metals (Pb, As, Cd, Hg).
4. Master overlap matrix
| Equipment / system | Reuse immediately | Retrofit required | Fail / net-new |
|---|---|---|---|
| Hammer / pin / roller mills | ✓ If food-grade MOC, cleanable | Validate cleanout; mesh change; dust seals | Resin-bound or porous surfaces without validated clearance |
| Plansifter / screener | ✓ | Mesh specification change | — |
| Ribbon / tumble blender | ✓ Dedicated preferred | Cleanout validation for dual-run | Shared without allergen/cross-contact SOP |
| Bucket elevator / conveyors | Partial | Washdown rating; material contact review | Cannabis-only duct with unvalidated THC residue |
| Pneumatic convey | Partial | HEPA upgrade; grounding | Undersized for fine kratom dust |
| Auger / VFFS packaging | ✓ | Labeler, batch/QR coder | Cannabis child-resistant only formats |
| Checkweigher / scale | ✓ | Recalibrate; software | — |
| Metal detector | ✓ | Sensitivity recert | — |
| Dust collection | Partial | ↑ CFM, HEPA, explosion protection | Undersized; no NFPA 652 program |
| Dryers / ovens | If raw leaf inbound | Profile validation for kratom ( alkaloid heat limits) | Terpene-focused cannabis dryers without temp mapping |
| Kill step equipment | Rare | Retrofit existing oven with validation | Most flour lines lack validated microbial reduction |
| CO2 / BHO / ethanol extraction | N/A powder-only | Extract SKU path | Idle CapEx if abandoned |
| C1D1 extraction rooms | N/A powder-only | Repurpose as clean room (costly) | Cannot commingle powder mill in C1D1 |
| Cannabis QA lab (bench) | ✓ Space reuse | New instruments / panels for alkaloid + micro | METRC-only LIMS workflows |
| Track-and-trace | — | — | METRC → 21 CFR 111 batch system |
| Quarantine warehousing | ✓ | Segregation signage | — |
| HVAC | Partial | Dedicated AHU, HEPA, pressure cascade | Shared return air with cannabis trim dust |
5. Dual inbound material paths
Path A — Raw dried leaf
| Additional step | vs pre-milled |
|---|---|
| Moisture verification | Required on receipt |
| Drying (if needed) | May reuse cannabis/h hemp dryers with validation |
| Full grind train | Coarse + fine mill |
| Kill step load | Moderate — surface bioburden |
| Quarantine time | Longer — full panel before process |
Path B — Pre-milled import
| Additional step | vs raw leaf |
|---|---|
| Coarse grind | Skipped |
| Kill step | Mandatory — highest microbial fail rate on import |
| Blend-before-test | Critical — sampling representative of lot |
| Dust control | Higher — finer ambient dust |
| Receiving risk | Often fails Salmonella on first COA |
Black Rock supply alignment: Define inbound mix early in discovery (09-FACILITY-QUESTIONNAIRE.md) — equipment list changes materially.
6. Hybrid facility (flour + extraction)
| Scenario | Recommendation |
|---|---|
| Flour line exists + extraction idle | Prioritize flour reuse for powder; extraction optional for tincture SKU |
| Extraction only (most pipeline labs) | Net-new milling + kill step; extraction idle or Scenario B segregated |
| Both active (cannabis) | Scenario B requires separate mills and AHUs minimum |
7. Benchmark cross-reference
| Benchmark | Best fit for |
|---|---|
| Super Speciosa | Pasteurization + blend-before-test + powder mill |
| Kraken Kratom | Dual-lab QA + milling/blending SOPs |
| Happy Hippo | Pre-milled repack + sterilization |
| MIT45 | Extract purification (not powder) |
| OTEMFG | Contract manufacturing model |
| Wasatch Extraction | UT GMP + multi-extraction (hybrid pivot) |
8. Discovery flags (TBD until site walkdown)
- [ ] Equipment MOC (304 SS vs carbon steel)
- [ ] Dust collector nameplate CFM
- [ ] AHU zoning diagram
- [ ] Existing kill-step capability (any validated heat treatment?)
- [ ] Inbound material mix (% raw vs pre-milled)
- [ ] Target throughput (kg/day)
