Industry focus
Geek Engineering supports companies that build commercial espresso machines, batch brewers, bean-to-cup units, cold-brew dispensers and coffee roasters with control-system design, electrical drawings, prototype builds, end-of-line test stands and connected-machine telemetry software. For roasting and coffee packaging plants, the same team engineers roaster, grinding and packaging-line controls. Certification testing stays with your listing lab.
A commercial coffee machine is a small process plant on a countertop. Water treatment, a boiler or thermoblock under closed-loop temperature control, a pump that sets brew pressure or flow, dosing by volume or weight, and a cleaning cycle all run from one controller, and that controller has to behave the same across thousands of units installed on different water and different electrical supplies.
What decides whether a coffee OEM's launch goes smoothly usually sits outside the industrial design: a control architecture that holds temperature shot after shot, wiring and documentation a contract manufacturer can build from, a test stand that proves every unit before it ships, and field data that shows the service team which machines are scaling or drifting before a café calls.
Roasters and coffee packagers have different problems, among them roast-profile repeatability, chaff and afterburner interlocks, and degassing-valve packaging under nitrogen. They share one requirement with machine builders: control logic documented well enough that the next engineer can maintain it.
Scope
Project process
Define beverages, throughput, utilities, target markets and the listings the product needs.
Select controller, sensors and actuators, and specify the temperature, pressure and dosing loops.
Build or instrument a prototype and record temperature stability, flow accuracy and recovery.
Release drawings, BOMs and test limits a contract manufacturer can build and check against.
Commission the end-of-line tester, train its operators, and hand over code and documentation.
| Machine type | Control challenge | Engineering focus |
|---|---|---|
| Commercial espresso machine | Brew-temperature stability across back-to-back shots | Boiler or thermoblock PID tuning, heater sizing, group-head sensing |
| Batch and pour-over brewers | Consistent volume and contact time across batch sizes | Flow-meter calibration, spray-head timing, recipe structure |
| Bean-to-cup / super-automatic | Dose and grind repeatability with little operator input | Grind-by-weight feedback, brew-unit sequencing, cleaning cycles |
| Cold-brew and nitro dispensers | Concentrate ratio and gas infusion at serving temperature | Ratio dosing, gas-pressure control, refrigeration interlocks |
| Coffee roasters | Repeatable roast profiles and fire safety | Bean-temperature logging, burner modulation, afterburner and chaff interlocks |
We do not publish fixed prices: these are the factors that determine effort. A scoped proposal follows the technical fit review.
We are not a contract manufacturer and we do not certify products. Production assembly stays with your factory or contract manufacturer, listing tests are run by an accredited lab, and pressure-vessel, gas-appliance and combustion approvals follow the rules of each market you sell into. Our part is the engineering that gets a design through those gates with fewer surprises.

Yes, at the level of control architecture, temperature and pressure control logic, electrical schematics, harness drawings and validation testing. Board-level electronics and certification testing are scoped per project with your electronics team, a specialist partner and your listing lab.
It depends on the market. In North America, commercial brewers are commonly listed to UL 197 for electrical safety and to an NSF/ANSI food-equipment standard for sanitation, and a wireless module brings FCC Part 15 into scope. Your listing lab confirms the exact standards; we design and pre-test against them.
Field conditions are harsher than a lab bench: supply voltage sags, hard water scales heating elements, ambient temperature swings and peak-hour demand outruns the test pattern. Instrumented testing under those conditions usually shows whether the fix is control tuning, heater sizing or sensor placement.
Typically water and steam leak tightness, heater function and recovery, pump pressure, flow-meter calibration, valve operation and electrical safety checks such as ground continuity. Every result is stored against the serial number so quality and service teams can trace a unit later.
Yes. Roaster work covers bean and exhaust temperature logging, burner modulation, roast-profile recipes, cooling-tray sequencing, and the afterburner and chaff interlocks that limit fire risk. Combustion safety devices remain listed components installed per their manufacturer's instructions and local code.
Yes. We design the data model and software that move shot counts, error codes, cleaning compliance and maintenance counters from each machine's controller into a cloud database, with dashboards for your service team and distributors.
