Industry focus
Geek Engineering engineers controls for candy and confectionery production, including sugar cooking, chocolate tempering, depositing, starch-mogul and starchless gummy lines, enrobing, cooling tunnels, panning and wrapping, for manufacturers, co-packers and the OEMs that build confectionery equipment. The work centers on temperature and weight control, servo synchronization, recipe-driven changeover, and the allergen and sanitation constraints food plants work under.
Confectionery is unforgiving process control. Chocolate tempering depends on a multi-stage temperature curve held within a degree or two; sugar syrup changes viscosity with every few degrees of cook temperature; and a depositor that drifts by a fraction of a gram across a mold row becomes give-away or underweight packs by the end of a shift.
Most candy lines are assembled from machines built by different OEMs: a cooker from one, a depositor from another, a cooling tunnel and a wrapper from two more. The losses tend to appear between those machines, as mismatched speeds, recipe parameters typed in by hand at every station, and changeovers that take longer than the run that follows them.
Seasonal demand makes it harder. Holiday SKUs, short runs and new shapes arrive on a fixed calendar, so the control system has to make changeover, recipe management and allergen sequencing predictable rather than heroic.
Scope
Project process
Review equipment, recipes and loss data to find where temperature, weight and changeover cost most.
Define recipe structure, machine handshakes, temperature loops and servo synchronization.
Program and simulate against the line's I/O so commissioning time stays short.
Cut over in planned shutdowns, with product trials and documented parameter tuning.
Deliver as-builts, backups and training before the next seasonal peak.
| Process | Critical variable | What goes wrong without control |
|---|---|---|
| Hard candy and caramel cooking | Final cook temperature and moisture | Grainy or sticky product, color and texture variation |
| Chocolate tempering | Multi-stage temperature curve | Bloom, poor snap and loss of gloss |
| Gummy depositing | Deposit weight and syrup temperature | Underweight pieces, tailing and mold-fill errors |
| Enrobing | Coating viscosity and curtain temperature | Uneven coating weight and give-away |
| Cooling tunnels | Zone temperature and humidity | Condensation, sugar bloom and sticking at the wrapper |
| Wrapping | Product pitch and registration | Jams, misaligned wraps and seal failures |
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 confectionery equipment manufacturer, a food-safety auditor or a recipe developer. Formulation, FSMA and allergen programs, and certification audits stay with your team and your auditors, and machine fabrication stays with the OEM or a fabrication partner. We engineer the controls, electrical design and integration that connect them.

Usually, yes. Most cookers, depositors, tunnels and wrappers expose hardwired signals or industrial-network interfaces for speed, ready and fault states. We define the handshakes, coordinate speeds from one line controller and push recipe parameters to each machine, so operators stop re-entering them at every station.
By closing the loop: checkweigher averages feed back to the depositor's piston stroke or servo profile, syrup temperature is held tightly enough to keep viscosity stable, and recipe limits stop targets drifting upward. How much that saves depends on today's weight spread, which we measure first.
We engineer servo motion, recipe structures, HMI screens and electrical drawings for builders of depositors, enrobers, cooling tunnels and other confectionery machines, together with the documentation and FAT procedures their customers expect when a machine ships.
They can make a changeover verifiable: HMI-guided cleaning steps, sign-offs, interlocks that block a run until verification is recorded, and records tied to the lot. The allergen program itself, and proof that the cleaning works, stays with your food-safety team.
It can be. Sugar, starch and cocoa powder are combustible dusts, and NFPA 61 and NFPA 652 call for a dust hazard analysis in food facilities. Electrical equipment in affected areas has to suit the classification that analysis sets, which our design follows rather than decides.
Outside your seasonal peaks, with the program developed and simulated offline first. A staged cutover, one machine or zone per shutdown, keeps the line producing through the upgrade and leaves a rollback path at every step.
