The Peachey Proton
Robust. Savvy. Dynamic.
Crafted for precision roasting in a compact footprint, the Proton is an 8 lb fluid bed roaster designed for specialty coffee operations that value control and repeatability. Offering granular thermal data, advanced automation with manual override, and exceptional batch to batch consistency, it delivers performance normally reserved for larger systems - without sacrificing space or efficiency.

ENGINEERED ADVANTAGES
What Makes the Proton Different
The Proton isn't a repurposed hot air system-it's a purpose built specialty fluid bed platform. Every structural and control decision is made to increase thermal stability, reduce maintenance, and deliver pristine flavor development across a full, true 8 lb batch capacity (tested up to 10 lb in development).
Overbuilt Stainless Chassis
1/8" thick stainless plate & premium components minimize flex, hotspots, and long term fatigue for decade scale reliabilty.
True 8 lb Capacity
Roast a full 8 lb production batch repeatedly-no 'marketing capacity'. Consistent loft and heat application across batch size.
Four 2mm Thermocouples
High resolution bean mass & environmental data streams feed precise profile control & post roast analysis.
Integrated Cooler & Stirring Arms
Dedicated blower & mechanical agitation rapidly end development; unload & cool efficiently without manual stirring.
Automation Ready (Artisan)
Ships with dedicated computer & screen plus configuration files. Install Artisan (license requirements prevent pre-install) and begin automated logging immediately.
Fine Control & Repeatability
Responsive heat & air adjustments for tight roast curve shaping; ideal for dense, high elevation & delicate ferment lots.
Lower Operating Costs
Efficient heat transfer & robust components decrease energy waste and downtime, improving cost per lb over life.
Serviceability Built-In
Straightforward access panels; common size fasteners; modular assemblies reduce repair time & inventory.
PRECISION FOR SPECIALTY
Designed for Modern Profile Strategy
Whether you're tuning early drying, extending Maillard for sweetness, or modulating post first crack development for higher solubility, the Proton gives you actionable, granular data and responsive controls. That's how you consistently showcase origin, process, and fermentation nuance.

FAQ
Questions & Answers
Is the deposit really refundable?
Yes. Your 50% deposit is fully refundable up until the week we begin building your specific unit.
Why isn't Artisan pre-installed?
Licensing restrictions prevent us from shipping it installed. We include the configuration files and guide so you can install and be ready within minutes.
What utilities do I need?
Standard electrical & venting requirements will be confirmed on the pre-build call; we provide a checklist so installation is frictionless.
Typical requirements are 60 amps 240 volts single phase
How many roasters per month?
We currently produce two Proton units per month to maintain build quality and rapid iteration of improvements.
Can I finance the purchase?
Yes. Bank or equipment financing is common. Your reservation confirmation and invoice can support loan documentation.
What support is included?
Remote orientation plus baseline profile assistance. Additional consulting or profile development packages are available.
