The source URL contains ZSJ-II, but the product description and technical table consistently identify the machine as ZPJ-II. ZPJ-II is used on this page.

High-capacity line architecture

Four-stage rolling, sealed filling and trim recovery

ZPJ-II is designed for continuous frozen-dumpling production. Rested, folded dough enters automatic feeding and passes through four independently controlled rolling stages. Progressive reduction develops a uniform wrapper without forcing final thickness in one aggressive pass. Photoelectric sensing coordinates dough supply with forming demand; filling and extrusion-forming modules then create the dumplings before conveyor discharge.

The published 60,000–70,000 pieces per hour applies within the stated 5–20 g range and must be reconciled with mold layout and acceptance criteria. Scheduled sanitation, dough changes and freezer loading affect realized hourly output. Although the source URL contains “ZSJ-II,” its product description and specification table consistently identify ZPJ-II, which is retained here.

Independent rolling control

Multiple rolling surfaces and single-side adjustment allow thickness and alignment correction while maintaining a continuous dough band.

Sealed filling supply

The movable, adjustable filling system is designed to reduce leakage and manage juicy fillings while keeping dosing aligned with the forming station.

Trim recovery

Excess wrapper material is returned for controlled reuse. The acceptable ratio must protect dough hydration, age, color, texture and food-safety controls.

Removable contact parts

Cleaning parts are removable, supporting a defined disassembly, allergen verification, inspection and restart procedure.

Upstream continuity

Mixers, resting equipment and dough handling need to supply uniform material continuously. A buffer strategy prevents every batch change from stopping the line. Filling temperature, particle distribution and free juice must also remain controlled.

Downstream capacity

At this output, inspection, flouring, product spacing and the IQF freezer must accept the same flow. The 7 m machine footprint also needs service clearance and safe sanitation-part removal routes.

Buyer questions

ZPJ-II high-speed dumpling line FAQ

Which products fit the published capacity?

The official range is associated with 5–20 g dumplings. Weight, mold positions and material behavior must be confirmed before contractual output is set.

Why use four dough rollers?

Progressive reduction creates a stable thin sheet while allowing independent alignment and thickness control.

Can trim be reused without a limit?

No. Returned material changes dough age and hydration; the acceptable proportion must be established through product-quality and food-safety testing.

Who is this line for?

It suits frozen-food factories, central kitchens and large producers with adequate mixing, material handling and freezing capacity.

Engineering selection guide

Specify High-Speed Automatic Dumpling Machine from the finished product backwards

A reliable quotation starts with the product and process target rather than a catalogue capacity alone. Provide piece shape, target weight, wrapper thickness, filling particle size, dough-to-filling ratio and downstream cooking or freezing. Samples, drawings and representative raw materials allow the supplier to identify the working configuration and any limits that should appear in the signed specification.

Published capacity is a reference condition, not an unconditional guarantee for every recipe. Sustainable performance must be measured as accepted product after normal rejects and interruptions. The acceptance plan should record piece-weight variation, seal integrity, wrapper damage, filling giveaway, reject rate and accepted pieces per hour. Agree the run duration, staffing, utility conditions and sampling frequency before the factory acceptance test so both parties evaluate the same result.

Factory integration

Confirm voltage and frequency, connected load, compressed air, water, drainage, exhaust or refrigeration where applicable. Check loading height, discharge direction, service clearance, floor loading and the real interface with upstream and downstream equipment.

Hygiene and changeover

Review dough and filling contact parts, mould access, residue recovery, allergen changeover and sanitation verification. The sanitation method must suit the machine’s electrical protection and the factory’s documented food-safety program.

FAT and site acceptance

Use the intended material and product format. Record start-up loss, stable output, quality variation, alarms, downtime, cleaning time and changeover time. Repeat critical checks after installation with actual site utilities and trained operators.

Information for a proposal

Send product photos or samples, formula where relevant, target hourly output, shift pattern, pack or downstream format, factory layout and utility schedule. Mark mandatory requirements separately from optional future expansion.

Application fit

Applications for High-Speed Automatic Dumpling Machine

Best suited to formed dumplings, gyoza, wonton, shumai or khinkali when the tooling, wrapper condition and filling properties are validated for the required product. Final suitability should be confirmed with representative product trials and the agreed acceptance criteria.
