Pre-Roll Infusion Machine

What a pre-roll infusion machine actually does

An infused pre-roll carries a dose of concentrate inside the flower — injected, not sprayed or soaked — so the unit smokes evenly and the potency on the label matches the potency in the joint. Done by hand with syringes, infusion is slow, inconsistent, and hard on staff: doses drift through a shift, viscous concentrates clog and cool, and output caps at what a person can steadily inject.

A pre-roll infusion machine replaces the syringe with a recipe: each unit receives the same dose, at the same depth, at the same temperature, hour after hour. Operators load pre-rolls and select a stored recipe; the machine handles dosing, placement, and consistency.

Hash holes: the format driving demand

A hash hole (or "donut") pre-roll carries a visible center channel of concentrate running the length of the joint. The format rewards precision — the channel has to be clean, centered, and consistent to earn its shelf price. Jiko+'s donut-maker needle and heat management were built for exactly this: viscous rosin flows at the right temperature and lands as a clean center placement, up to 700 units per hour on rosin and 1,200 on distillate.

Manual vs. automated infusion

• Dose accuracy. Hand-injected doses drift with operator fatigue and concentrate temperature. Recipe-controlled injection holds ±0.03g per unit — potency compliance you can print on the label.
• Viscosity range. Syringes fight thick concentrates. A heated system that handles 500–100,000 cP runs everything from standard distillate to heavy rosin without thinning or additives.
• Throughput. One operator and a machine produce up to 1,200 infused joints per hour — steady output that doesn't slow down at hour six.
• Payback. Most operations producing 500+ joints a day see positive ROI; typical payback lands under ten months (run your own numbers in the ROI calculator).

What to look for in an infusion machine

1. A published dose-precision figure — not "consistent," a number.
2. The viscosity range, stated in cP — this decides whether your concentrate menu runs without compromise.
3. Hash-hole capability, if the format is on your roadmap — center placement is a different engineering problem from simple injection.
4. Honest throughput per finished unit, for your concentrate — distillate and rosin numbers differ.
5. Support you can reach: remote diagnostics, overnight parts, a warranty measured in operating hours.

Built by the people who created the category

Jiko created automated pre-roll infusion; Jiko+ is its current generation — patented, deployed across production facilities, and refined for hash-hole formats with the donut-maker needle and advanced heat management. It runs on standard 120V power in a 42-inch footprint and ships with on-site training and a 2,000-operational-hour renewable warranty.
