Quick Start Guide
Chocolate Refiner
Everything you need to set up, season and run your stone refiner — first-use cleaning, refining and conching, washing and long-term care.

Minimum batch
Of rated capacity — keep the shaft covered.
12–72h
Conching
Longer develops flavor and cuts bitterness.
HOW IT WORKS
Heat, minimal pressure, patience.
A stone refiner grinds and conches in one drum. Granite rollers turn against the base stone, shearing cacao into a progressively finer paste while friction warms the mass and cocoa butter is released.
Three things make or break a batch: gentle heat to keep the chocolate fluid, minimal stone pressure set through the Top Lock Nut, and gradual loading so the stones never stall. Keep the roller shaft covered with product and let time do the rest.
STEP BY STEP
Setup, first use & care.
Everything you need for a confident first batch — and clean, reliable runs after.
Before you begin
Inspect the machine
Carefully inspect your Chocolate Refiner for any shipping damage before first use. Check all parts — stone rollers, drum, lid, shaft, and top lock nut — against the diagram in your manual.

Critical step
Machine setup
Correct stone pressure adjustments via the Top Lock Nut are critical. For stainless steel assemblies, only a single turn after the spring engages is needed. This low-pressure approach results in faster, more even refining and better flavor development.
Place the machine on a stable, level surface. Ensure the power cord reaches your 110V outlet without stretching. Never use an extension cord.
First use only
First-use cleaning
Before your first chocolate batch, remove fine stone dust from the granite grinding stones. Mix vegetable oil and sugar at 70% oil / 30% sugar for a total weight of 2½ – 3 lbs. Run for 10–15 minutes, then discard completely.
Do not skip
Stone dust from new grinding wheels affects flavor and texture. This step is mandatory before your first chocolate batch.
After every use
Washing & drying
Remove drum and roller stones and disassemble completely. Wash with mild soapy solution and rinse well. Use the included wire brush inside the roller stone grooves.
Not dishwasher safe
Air dry completely. Use a blow dryer for a few seconds — moisture in the stone hub must be fully removed before reassembly.
After washing
Reassembly
Refer back to Step 2 — Machine Setup. Ensure the drum is fully seated, roller stones correctly positioned on the shaft, and the Top Lock Nut is in place before starting.
Before you start
Double-check all parts are completely dry before reassembling. Even small amounts of moisture can affect your chocolate batch.
Most important step
First batch — refining & conching
Heat. Minimal pressure. Gradual ingredient addition.
These are the three keys to a successful first batch. Loading too quickly stops the stones — gradually add cacao nibs and let them form a thick paste, applying gentle heat with a blow dryer if needed. Once you reach paste consistency, turn the Top Lock Nut to apply pressure.
Always keep the roller stone shaft covered with product. Minimum batch size is 40% of rated capacity.
What to look for
The paste should look like chunky peanut butter before you add more nibs. Watch for it to glisten — that sheen is cocoa butter releasing.
Optional
Additional conching
To conch without additional refining, loosen and remove the Top Lock Nut. The stones float freely over the chocolate, promoting volatilization and deeper flavor development.
Flavor development
Extended conching (12–72 hours) develops complexity and reduces bitterness. The longer you conch, the smoother and more rounded the flavor profile.
When ready
Emptying the drum
Once satisfied with texture and flavor, empty the drum using the technique shown below.
Never store in the drum
Always empty, wash, and dry after each use.
Between uses
Storage
Wash, dry, and fully reassemble before storing. Store clean, dry, and covered with the lid in a cool, dry location away from sunlight and humidity.
Long-term care
Use a blow dryer to remove all moisture from stone hubs and the drum interior before covering. A well-maintained machine lasts for many years of production.
REFINING VS CONCHING
Two modes, one machine.
The same drum refines and conches — the Top Lock Nut decides which.
Refining
Top Lock Nut engaged. Stones grind under light pressure until the paste glistens — that sheen is cocoa butter releasing. Add nibs gradually so the stones never stall.
Conching
Top Lock Nut removed. Stones float freely over the chocolate; volatiles escape and the flavor rounds out. 12–72 hours builds complexity and cuts bitterness.
Daily care
Disassemble fully, wash with mild soap, brush the stone grooves and air-dry — blow-dry the hub. Never dishwasher. Never store chocolate in the drum.

Frequently asked questions.
Run at least 40% of the machine's rated capacity, and always keep the roller stone shaft covered with product. Smaller batches can stall the stones and refine unevenly.
Yes. Before your first chocolate batch, run a mix of 70% vegetable oil and 30% sugar (about 2½–3 lbs total) for 10–15 minutes, then discard it completely. This removes fine stone dust from the new grinding stones and protects the flavor and texture of your first batch — it's mandatory.
Refine until the paste glistens — that sheen is cocoa butter releasing. To conch, remove the Top Lock Nut so the stones float freely over the chocolate; 12–72 hours develops complexity and reduces bitterness. The longer you conch, the smoother and more rounded the flavor.
Use minimal pressure. For stainless steel assemblies, a single turn after the spring engages is enough. Low pressure refines faster and more evenly — and develops better flavor — than over-tightening.
No part is dishwasher safe. Disassemble completely, wash with a mild soapy solution, brush inside the roller stone grooves with the included wire brush, and rinse well. Air-dry, then use a blow dryer to remove all moisture from the stone hub before reassembly.
