Standardized Dough Dividing Equipment: Technical Characteristics and Application Analysis of Dividin

In the industrialized production process of Chinese pastries, dough division is a core process that determines product consistency and production efficiency. As a specialized dough dividing machine, the dough divider automatically divides kneaded dough into uniform dough portions of a set weight, and is widely used in the large-scale production of steamed buns, dumplings, and other pastries. With the increasing demands for standardization and automation in the food processing industry, the dough divider has become a basic piece of equipment in central kitchens, frozen food factories, and chain restaurant kitchens.

I. Basic Definition and Classification of Dough Dividing Machines

(I) Definition A dough dividing machine, also known as a dough portion divider, is a food processing machine that uses mechanical transmission and control technology to quantitatively divide continuous dough into independent dough portions. Its core function is to achieve uniform dough portion weight, smooth cuts, and minimal gluten damage, providing standardized raw materials for subsequent shaping processes.

(II) Mainstream Classifications and Characteristics Spiral dough dividing machines use a auger spiral pushing structure. The rotating spiral blades compress and transport the dough to the cutting station, where it is cut with a cutter. It has a simple structure, low cost, and is suitable for medium to low hardness ordinary dough. The equipment is small in size and easy to operate. However, spiral extrusion can cause friction and stretching of the gluten, potentially affecting the elasticity of high-gluten dough or sourdough, resulting in a denser texture in the finished product.

The flat-push (press-type) dough ball machine uses a piston-push principle, without a spiral auger structure. A servo motor or pneumatic system drives the push rod to uniformly push the dough to the cutting device, without any rotation or extrusion throughout the process. Its core advantage is that it does not damage the gluten, fully preserving the dough's elasticity. It is suitable for special types of dough such as sourdough, fermented dough, high-gluten dough, and frozen dough, producing a soft finished product that is less prone to collapsing during steaming. It operates quietly, has high stability, and allows for precise fine-tuning of the dough's weight.

The static pressure dough ball machine uses hydraulic or servo constant pressure drive to apply uniform pressure to the dough for extrusion and segmentation. It has stable force and a smooth cut surface, making it suitable for large-scale continuous production and commonly used in large food processing plants.

II. Core Structure and Working Principle

(I) Core Structure Composition
Feeding Unit: Composed of a dough inlet hopper and a feeding chamber, used to place the dough to be segmented and guide it smoothly into the conveying mechanism.

**Quantitative Conveying Unit:** The spiral type uses auger blades, while the flat type uses a pusher piston. Combined with a servo control system, this achieves quantitative dough conveying and controls the weight of each individual portion.

**Cutting Unit:** Includes a cutter and cutting drive device, made of stainless steel with sharp blades to ensure clean, non-stick cuts.

**Power and Control Unit:** Consists of a motor, PLC control panel, and frequency converter, enabling equipment start/stop, speed adjustment, weight parameter setting, and fault alarms.

**Frame and Discharge Unit:** The frame is primarily made of stainless steel profiles, ensuring stability and corrosion resistance. The discharge port is equipped with a guide plate for easy collection or transport of dough portions to the next process.

(II) Workflow:
1. Manually feed the kneaded dough into the hopper.
2. Start the equipment; the conveying unit pushes the dough at a uniform speed to the cutting area.
3. The control system controls the pushing length according to the set weight; the cutter completes the cutting.
4. The divided dough portions are discharged through the discharge port, completing a single cycle. Continuous operation enables mass production.

III. Key Technical Parameters and Performance Indicators
