Automatic Phoenix Roll Machine — Seaweed and Pork Floss Snack Production Line by UDTECH (UD-02)
The UDTECH UD-02 can produce filled phoenix rolls-the seaweed-wrapped, pork-floss-and-granule-filled crispy wafer snack-at 720 pieces/hour with full-time automation from batter mixing to roll demolding. One smart controller manages the rotation at each step: laying the seaweed, dispensing the batter, heating the batter for baking, folding the dough sheet into a cake, rolling that cake around the fill, and demolding the roll. That process supplants hand-rolling.

Solving Production Bottlenecks in Phoenix Roll Manufacturing
There’s a labor problem in making phoenix rolls. On a typical line, food workers turn and shape individual savory, seaweed-and-pork-floss-stuffed wafers at rotary stages by hand, and output eventually maxes out where operators’ hands tire. It’s an inconsistent product, with variation in shape, fill weight, and the incidence of cracked rolls, as tired hands tend to do more damage to fragile wafers. For commercial food companies serving grocery, online shopping, or gifting marketplaces, hand-rolling has created an impasse between throughput and consistency.
UDTECH engineers addressed that impasse in designing the UD-02, a fully automatic phoenix roll machine in which the entire wafer is formed through six successive rotary stations operating under a single controller: seaweed layout, batter filling, heating, folding into a cake, rolling, and roll ejection onto the transport conveyor. Precisely controlled heat holds the wafer in a narrow window of rigidity and pliability for clean folding and rolling, which prevents premature cracking. Output is consistent, clean-tasting rolls at production speeds that satisfy retail packaging and contract-manufacturing needs: 720 per hour, with a clear gain in pieces produced per operator.
ENGINEERING NOTE — WHY SEAWEED FILLING CHANGES THE MACHINE
A number of features are specific to fabricating the sandwich of seaweed sheet and pork-floss-and-granule filling. Its seaweed sheet must be laid evenly and held in alignment before the batter sets; because the floss is low-density and fibrous, a specialized depositor meters the mix without crushing the strands. UD-02 meets that with a dedicated seaweed layout station ahead of the depositor, where photoelectric sensors track sheet position as it advances with each step of the rotation. Switching roll type is a recipe adjustment for the granular fill materials rather than a hardware change, so the single, customizable UD-02 line can produce many varieties.

Filling Versatility — One Machine, Several Phoenix Roll Variants
UD-02 working system features both an interchangeable filling depositor and laying, as main distinguishing characteristic in opposition to the standard 1-product fixed line machines.
To be able to produce different filled Phoenix Rolls including seaweeds (chicken/pork flavor fillings) or powder (matcha/coffee/sugar flavor fillings) using the identical, flexible machinery by switching the product blended to seasonality & gifting marketplace demand-without needing another machine unit.
The Rotary-Station Workflow
Working on a Continuous rotary manner, every turn of the table moves the specific rolled cake with the next stage in sequence of the different machine parts in the production-thus as soon as one machine component completes, the next machine part starts the next working component in real-time of an entire line operation and vice-versa, e.g. a roll leaves the moulder as a subsequent one moves forward into mold, into folding, into heat-transfer module, etc..

| Driver | The UD-02 fits when | Talk to us about a line when |
|---|---|---|
| Output target | Up to ~720 pcs/h on a single line | You need parallel lines for higher volume |
| Product mix | Seaweed / pork floss / powder-filled | You add unrelated snack formats |
| Channel | Retail, e-commerce, gift-box packaging | You need integrated downstream flow-pack |
| Plant power | Three-phase 380 V available | You require a different supply voltage |
| Floor space | ~4.6 m² footprint plus clearance | You want a multi-machine cell layout |
Engineering Note — Servo Linkage, Sensing, and Air
Multi-channel servo linkage drives the feeding, folding, and laying stations electronically rather than off a single mechanical cam, so the timing between stations can be programmed in the PLC for different fillings and wafer recipes. Position is checked at every point of the working table through fiber-optic photoelectric sensors, which keeps a misfed wafer or a missing seaweed sheet from turning into a jam. Power consumption is 12 kW on a three-phase 380 V supply, and a 0.2 m³/min compressed-air feed drives the demolding and discharge actuators — plants should size their air line and dryer to hold ≥0.6 MPa continuously during production.
Automatic vs Manual Phoenix Roll Production — Performance Comparison
An honest benchmark for a phoenix roll machine is not another supplier’s spec sheet — automated competition in this niche is thin. A more useful comparison is against the manual and semi-automatic methods most producers run today, as set out below. Those manual figures are industry-generic ranges; they shift with each crew’s spec and skill, and none were taken directly from UDTECH operations.
| Metric | UDTECH UD-02 (automatic) | Manual / semi-automatic (typical) |
|---|---|---|
| Output per line | 720 pcs / h | Highly variable, operator-bound |
| Labor per line | 1–2 attendants | Several rollers per shift |
| Shape & filling consistency | Servo-controlled, uniform | Drifts with operator fatigue |
| Filling changeover | Recipe-driven | Re-train / re-set by hand |
| Hygiene | Full stainless enclosure, less hand contact | High hand-contact |
| Temperature control | Automatic, closed-loop | Manual judgement |
| Footprint | ~4.6 m² | Bench space + multiple stations |
| Power | 12 kW (380 V) | Mostly manual |
Financial & Operational Insight
What finance wants to see is labor against output. Shifting filled phoenix roll production from hand-rolling to a single automatic line collapses the output of a full rolling crew onto one machine run by one or two attendants — a step-change in labor efficiency — while tightening the shape and filling-weight control that drives both consumer acceptance and lower giveaway. Across food-line automation, producers who invest on total cost of ownership rather than purchase price report much better ROI, higher plant uptime over the years, and fewer disruptions — as true for phoenix rolls as for the broader snack sector.

Automating hand-rolled snacks has a three-pronged impact on plant economics - all of it positive. These numbers reflect industry averages for the snack and biscuit industries, based on studies that measure total cost of ownership. They are sectoral, not equipment-specific benchmarks, and should serve as indicative figures rather than guaranteed, firm returns; the ROI from our UD-02 line is necessarily driven by the labour rate and output level at which your operation runs, and the efficiency of your utilization; for that reason, we prepare a bespoke ROI worksheet for each quote.

Pattern 1 — Hand-rolling to UD-02 (typical transition)
Switching from a hand-rolling crew to a single UD-02 line for filled phoenix rolls lets operations aggregate the throughput of many rollers into one machine run by one or two attendants, while holding tighter control on shape and filling weight across a shift. Payback on this kind of labor-led snack automation commonly lands in the 14–22 month range.
Pattern 2 — E-commerce & gift-market scale-up
For many producers that supply the e-commerce and gifting channels, ensuring a uniform appearance across a very large production batch is critical, as visual inconsistency can result in rejected products on even a small delivery. Through consistent output shape, controlled by servo forming and closed-loop temperature control, our automated system dramatically reduces the incidence of both rework and giveaway in a gift presentation.
Pattern 3 — Multi-variant production
If your operations routinely produce and supply several varieties of phoenix roll, our recipe changeover function supports easy transitions from seaweed to pork floss, or powder fills - on the same line - which avoids investing in multiple dedicated lines and maximises the efficiency of a single UD-02 through-out the product range.
Each UDTECH quote includes a customized worksheet that accurately measures the economic returns at your operational level-incorporating your particular labour rates, target output, and level of asset utilization. Generic ROI metrics have their value in a high-level check; however, the data that actually gets signed off at finance centres on the specific kilogram/hour, attendant/line and waste/thousand pieces values that compound favourably over the years. The e-commerce/gift presentation requirement on phoenix rolls introduces another key metric that automation significantly influences; that is the percentage of product output passing visual inspection and control, and we can ensure that percentage improves on levels achievable by hand.
Food Safety Certifications & Compliance
UD-02 is engineered to the harmonized standards for food-contact materials, machine safety, and quality management. A full compliance set ships with every machine, and specific certificate numbers and issuing-body references are provided in the procurement package for your audit file. UDTECH builds every product to the regulations that apply across the food-processing sector as default scope rather than an optional upgrade, so a phoenix roll machine is held to the same framework as any other snack and bakery production equipment.
Engineering Note — Food-Contact Surfaces & Hygienic Design
Food-contact surfaces of the UD-02 use stainless steel grades recognized by the FDA as Generally Recognized As Safe under 21 CFR 175.300, with the corrosion resistance and cleanability required by 21 CFR 117.40. Full stainless-steel encapsulation of the contact zone, combined with a largely hands-off rotary process, makes the UD-02 a clear step up in hygiene and cuts the contamination risk intrinsic to hand-rolled product — which matters not just for shelf-life but also for the audit file.
Procurement Guide — Pricing · Lead Time · After-Sales

You can then review the details and request your individually quoted price for a UD-02 system.
Pricing Factors
ConfigurableA UD-02 quotation covers the equipment as specified at the contract point, and it varies with fill-system design, filling type (seaweed inlay or flavored filling), control architecture, warranty package, and integration options such as upstream dough-mixing or downstream cooling and packaging. Every factor is itemized in the quotation so your team can compare value line by line.
Indicative Lead Time
Configured per orderYour scheduled production from the signing of the contract, through the final acceptance testing to final packing ready for transit is coordinated by UDTECH. Please note, shipping and on-site installation is scheduled independently according to destination of client’s production site. UDTECH issues a definitive and dated schedule of projected machine completion at the point of order, typically proving significantly faster to produce and install the machine than an equivalent custom-built machine for similar application.
Minimum Order
1 lineSingle-line orders are the standard at UDTECH. Producers scaling capacity in stages commonly add further UD-02 lines later, sharing spare-parts inventory and operator training across the deployment as production grows.
Installation
On-site commissioningWe deploy our engineers to your facility to carry out the setup of your machinery, tuning of any specified recipe settings and the certification of live production of your product on site. UDTECH matches the seaweed filling settings with the forming and baking parameters of your new UD-02 by working with the UDTECH formulation at the point of the plant installation stage rather than post-install, which avoids issues and complications at a later date.
Operator Training
Operations + maintenanceOur engineers carry out two levels of hands-on, face-to-face training on site. Level one concentrates on operation — recipe changes, daily start-up, and cleaning routines — while level two covers maintenance (routine tasks, calibration, troubleshooting). We supply full training and operating instructions in English and Chinese, with other languages available on request.
Warranty & Support
12 months + lifetime remoteA twelve-month warranty is applied to the basic parts and equipment included with your UD-02 installation starting from the day you perform the factory acceptance testing.

Phoenix Roll Machine — Frequently Asked Questions
A phoenix roll is a crispy rolled wafer snack wrapped tightly around a savory filling — most often seaweed (nori) and pork floss, sometimes with granular powder blends. Its wafer skin is baked and rolled while still warm so it sets into a crisp shell, which is what gives the snack its signature crunch. UDTECH's UD-02 produces this automatically across six rotary stations: it lays the seaweed sheet, injects the paste filling, heats, folds the cake, rolls, and demolds the finished roll onto the conveyor — no hand-rolling, and uniform shape from the first piece to the last.
Interchangeable fillings are the point of the UD-02: seaweed / nori sheets, pork floss, and various granular powders, plus custom blends. Seaweed is laid and registered at a dedicated station, floss and powders are metered by a servo depositor that won't crush the fibrous material, and switching variants is a recipe change rather than a hardware change — so one machine produces several phoenix roll variants for different channels.
UD-02 produces 720 pieces per hour, fully automatic. It draws 12 kW on a three-phase 380 V supply and needs compressed air of 0.2 m³/min at ≥0.6 MPa for its pneumatic stations. At 2300 × 2000 × 1400 mm (about 4.6 m²) and 960 kg, it fits compact production rooms while still running as a continuous rotary line.
UD-02 is quoted as a configured line, not a fixed catalogue price. Final pricing depends on filling-system configuration, control-system tier, certification scope, spare-parts package, and any upstream or downstream integration, each itemized in the quotation. Buyers who select on total cost of ownership rather than unit price tend to report higher multi-year ROI, and UDTECH supplies a TCO worksheet during quotation so your finance team compares on the same basis. Contact UDTECH for a configured quote.
Both form a crispy rolled wafer, but they differ by filling and recipe. A phoenix roll is savory — seaweed and pork floss — while a wafer egg roll is usually sweet, hollow or cream-cored. That changes the filling stations: a phoenix roll line needs a seaweed-laying station and a floss-friendly depositor. UDTECH builds both; if you produce sweet wafer rolls, see our automatic wafer egg roll machine.
Yes. Multi-channel servo linkage lets station timing be tuned in the PLC for different fillings and wafer recipes, and the depositor handles seaweed, floss, and powder through recipe settings. UDTECH calibrates your filling formulation to the UD-02 during on-site commissioning.
UD-02 is engineered to CE (Machinery Directive 2006/42/EC, moving to EU 2023/1230), FDA 21 CFR 117 and 21 CFR 175.300 GRAS stainless steel, ISO 9001, GMP, and HACCP. Specific certificate numbers come in the procurement package.
Standard support: a 12-month warranty on main components from factory acceptance test, lifetime remote engineering help by email, phone, and video, and spare-parts recommendations at delivery. Two-track operator training runs during on-site commissioning.
