Driven by booming breakfast‑chain and frozen ready‑to‑eat food markets, many soup‑dumpling (xiao long bao) chain brands are facing tight production capacity. Traditional handmade xiao long bao heavily relies on skilled artisans. High labor turnover and rising labour cost, together with inconsistent weight & folding shapes from manual work, make it hard to maintain standardized supply for nationwide store networks. Recently, our company officially signed an automatic soup‑dumpling‑baozi machine project with a well‑known domestic xiao long bao chain brand. We deliver a complete pastry automation solution for the client's new‑built central kitchen, supporting large‑scale capacity expansion and consistent product quality across outlets.
Project Solution: Full‑chain Automation for Chain‑Brand Xiao Long‑Bao Production
This turn‑key solution is not limited to a single forming machine. It covers full workflow: dough preparation, filling processing, product forming and finished‑goods auto tray‑loading. The whole line seamlessly integrates QS400-600 Automatic Tray Loading. Freshly‑formed soup dumplings get neatly placed onto freezing trays automatically and flow straight to IQF tunnel, realizing end‑to‑end automated production from raw ingredients to frozen finished goods.
Production line configuration:
1.Pre‑processing unit: Vacuum dough mixer and frozen meat grinder for dough kneading and soup‑filling preparation, ensuring stable dough tenacity and well‑mixed juicy fillings.
2.Soup‑dumpling & baozi forming main unit: Optimized for thin‑wrapper juice‑rich xiao long‑bao. Capable of producing soup dumplings, pork buns and vegetable buns. Multiple product recipes are stored in touch‑screen HMI, shortening product change‑over time.
3.Auto tray‑loading unit (QS400-600 Automatic Tray Loading): Servo aligning mechanism guides xiao long bao into trays in preset rows and columns. Built‑in buffer dropping design prevents wrapper rupture and soup leakage, replacing low‑efficiency and uneven manual tray‑placing.
4.Central PLC control system: Food‑grade SUS304 stainless steel construction complying with food‑plant hygiene requirements. Real‑time production status readout and fault alarm simplify operator workload.
Key Pain Points Solved for Chain Soup‑Dumpling Operators
1.Cut down labour dependency and unlock higher production capacity Hand‑made xiao long‑bao output is capped by skilled workers, and staff turnover directly threatens order fulfilment. After automation deployment, manual labour at forming stations is greatly reduced. The production line supports long‑hour continuous running, coping with order growth from new retail stores and frozen e‑commerce channels.
2.Standardized output for consistent quality across all store locations Xiao long‑bao demands precise wrapper thickness, filling weight and folding appearance. Automatic equipment precisely controls wrapper and filling dosage, keeping piece‑to‑piece weight deviation within acceptable range. Uniform product specifications are maintained for outlets in different regions, avoiding quality fluctuation caused by hand‑making.
3.Flexible multi‑variety production for fast product iteration By quick mould swapping, one set of equipment can produce soup dumplings, pork buns, vegetable buns, red‑bean paste buns and more. It suits central‑kitchen requirements of multi‑SKU, small‑batch manufacturing and supports brand new‑product launches.
4.Smooth connection with downstream freezing process & less material waste Finished xiao long‑bao are directly transferred to trays via QS400-600 Automatic Tray Loading with minimal human contact. It improves food‑safety level and reduces wrapper damage during manual handling, cutting production material loss.
