Donut trucks (mini-donut and full-size)
Mini-donut operators run a Lil Orbits SS1200 or equivalent, a conveyor fryer that produces 1,200 mini-donuts per hour at 375°F oil. The machine itself is 15A/120V but the oil reservoir holds 12-15 lb and the heat recovery after a surge is the real throughput limit. We spec a dedicated filtration line so the operator can hot-filter oil mid-service without a 20-minute cooldown.
Full-size donut operators running cake or yeast donuts need a larger footprint: a Belshaw Thermoglaze or Donut Robot Mark VI in a fixed commissary, with the truck used for frying + glazing stations only. Yeast-risen donut production on a truck is possible but the proof timing (40-60 min at 95°F / 85% RH) requires a humidity-controlled proofer that most trucks don’t have room for. We build proofer cabinets on 22’+ trailers.
Ice cream trucks (scoop, soft-serve, and batch-frozen)
Scoop operators (Coldstone, Ben & Jerry’s, Häagen-Dazs pints) need deep well freezers, typically a Delfield F18 or similar 18 cu ft dipping cabinet at -10°F. We insulate these heavily (R-25 foam) because truck interior temps at a Texas festival can hit 140°F with the roof in direct sun. Standard insulation fails at that differential.
Soft serve operators run a Taylor C707 or Stoelting F231, twin-barrel soft-serve machines pulling 208V / 30A. The compressor cycle is brutal; we specify a dedicated 8kW generator with soft-start capability because a hard-start in-rush can trip standard inverters.
Batch-frozen / house-made ice cream operators use a Carpigiani LB500 or Emery Thompson CB350 batch freezer. These are 3-phase 208V machines, significantly more power than a standard truck’s single-phase 240V service. For batch-frozen builds we install a small rotary phase converter or spec a 3-phase generator.
Snoball / shaved ice operations
New Orleans snoball is a cult product and we’ve built three dedicated snoball trailers for operators running the block-ice shaving style. The core equipment is a Southern Snow SI-20 or Little Snowie Max block-ice shaver, which is mechanically simple (500-1,000W motor) but consumes massive block-ice inventory, 25 lb per 40-50 snoballs. We install a 2-door reach-in freezer dedicated to block-ice storage, separate from any syrup or topping refrigeration.
The syrup rail is where operators differentiate. A serious snoball operator carries 40-60 syrup flavors. We build a 48″ or 60″ bar-style syrup rack with rubber-gasket bottles, each on a 10-degree forward tilt so syrup pours without shaking. Cream-based toppings (condensed milk, ice cream fill, stuffed flavors) need their own refrigerated 4-pan well.
Crepe, pancake, and batter-based builds
Crepe operators run a Krampouz Billig CEBPA4 (round billig plate) at 400-430°F. 2,700W electric. The key spec is the surface seasoning, a new billig needs a 14-day oil cure exactly like a new pizza oven stone. We do the cure at our shop before delivery.
Pancake operators use a Chandler / Chromalox commercial griddle (same family as a burger griddle, but thermostatically controlled to 375°F). The throughput is 80-120 pancakes per hour on a 36″ surface. We see pancake builds mostly in tourist-destination markets (ski towns, beach resorts) where the ticket average supports the slower cook time.
