The ZKHM Series Vacuum Dough Mixer is core pre-processing equipment built for frozen food plants, large central kitchens and flour product manufacturers. It is widely used to prepare dough for frozen dumplings, wontons, siomai, fresh noodles, spring roll wrappers and other wrapper-based dim sum.

Ordinary atmospheric mixers trap large volumes of air inside dough during stirring. These trapped air bubbles are the main cause of wrapper cracking after freezing, breakage during forming, cloudy soup while boiling and dull, tough mouthfeel. Equipped with patented mixing paddles, the ZKHM vacuum dough mixer works in a sealed negative-pressure chamber and simulates hand-kneading motion. It accelerates hydration of gliadin and glutenin in wheat flour, forming a continuous, dense and even gluten network rapidly.

Dough from this machine is bubble-free, compact and glossy after cutting. It delivers far better elasticity, toughness and ductility compared with conventionally mixed dough. It fundamentally fixes most common quality defects of frozen dim sum wrappers at the dough preparation stage.

This series includes multiple capacity models such as ZKHM-300 and ZKHM-600. It can run independently or integrate seamlessly with GQ dumpling machines, WHP wonton machines, automatic shumai formers and tray arranging machines to build a complete automatic frozen dim sum production line. It serves as an essential pre-processing unit for automated dim sum workflows. For export orders, material, frame and electrical components can be adjusted to meet CE requirements for overseas food workshops.

Product Features

1.High-quality food-grade stainless steel construction

The main frame, mixing tank, stirring paddles and all parts that come into direct contact with dough are made of food-grade stainless steel. It meets domestic food safety standards and satisfies international hygiene audit requirements for export clients. Polished inner surfaces reduce dough adhesion for easy cleaning. The material is corrosion-resistant and rust-proof, stable for long-hour non-stop industrial production and extends machine service life.

2.Optimized seal and bearing structure for simple maintenance

The shaft seal and bearing assembly are redesigned for easier service. Unlike traditional mixers that require heavy disassembly, seals and bearings can be replaced quickly without taking apart the whole mixing chamber. It greatly cuts downtime during maintenance, reduces production interruption and lowers labor cost for routine upkeep.

3.Vacuum negative-pressure mixing for well-developed, consistent gluten

Mixing proceeds under stable negative pressure. Air is removed from the mixing chamber, enabling flour proteins to absorb water thoroughly and build a strong, uniform gluten network in a short time. The finished dough has a smooth surface with ideal toughness, stretchability and chewiness. It shows a natural pale yellow colour with excellent maturing performance, resists tearing during sheeting and produces translucent wrappers.

4.Higher water absorption rate, less flour consumption and lower production cost

With air eliminated from dough matrix, water molecules penetrate fully into protein structures. Under the same flour formula, vacuum kneading raises the water holding capacity of dough. You can produce more wrappers from the same weight of flour without sacrificing texture and quality. It reduces raw material waste and brings down the unit production cost for long-term mass production.

5.Patented paddle system, combines mixing, kneading and resting in one machine

The custom-designed patented mixing paddles follow a unique stirring track, different from conventional single-shaft mixers. One machine completes mixing, kneading and dough maturing in a single cycle. Freshly discharged dough is ready for sheeting and forming directly. No separate resting room or extra resting time is needed. It saves workshop floor space, simplifies production flow and lowers the risk of dough contamination during transfer.

6.PLC intelligent control with savable, adjustable process parameters

It adopts a PLC control system paired with an intuitive operation panel, simple for operators to learn. Users can freely set vacuum level and mixing duration according to flour type, wrapper recipe and final product. Multiple proven recipes can be saved and recalled. When switching between different products, calling preset parameters avoids inconsistent dough quality caused by manual adjustment, helping you achieve standardized batch production.

Technical Specifications (ZKHM-600 for reference)

Note: The ZKHM series also provides ZKHM-300 and other capacity options. Custom adaptation is available based on your workshop layout, required output, local power supply and export certification requirements. We also support full production line layout planning.
