Automatic Siomai Maker Machine for Commercial Siomai Production

An automatic siomai making machine is designed to produce siomai (also known as shumai or shumai dumplings) with consistent shapes, uniform wrappers, and accurately portioned fillings. It automates the main production processes, including dough sheeting, wrapper forming, filling dispensing, and siomai shaping.

Our SL-80 siomai making machines are available in fully automatic double-row, fully automatic three-row, and semi-automatic models. With different production capacities and adjustable product specifications, these machines can meet the needs of small food businesses as well as commercial food processing factories.

Whether you produce meat siomai or glutinous rice siomai, we can provide a suitable machine configuration and customized production solution based on your product requirements.

1. How Does the Automatic Siomai Maker Machine Work?

The automatic siomai making machine is specially designed to produce square-wrapper siomai. Operators only need to place the prepared dough and filling into their respective hoppers. The machine then automatically processes the materials into finished siomai.

The main working processes include:

• Dough Feeding: Prepared dough is placed into the dough hopper for continuous processing. The dough can be prepared using our multifunctional dough mixer .
• Multi-Roller Dough Sheeting: Multiple rollers gradually press the dough into sheets with uniform thickness.
• Wrapper Forming: The dough sheet is processed into square wrappers suitable for siomai production.
• Filling Dispensing: The filling system delivers a controlled amount of filling onto each wrapper.
• Automatic Shaping: The forming mechanism wraps the dough around the filling to create the characteristic open-top siomai shape.
• Finished Product Output: Formed siomai are discharged for subsequent steaming, cooling, freezing, or packaging.

The siomai maker uses program-controlled operation to coordinate the production process, reducing manual work and improving production consistency.

2. Main Features of the ST-80 Siomai Making Machine

Fully Automatic Production

The automatic model integrates dough sheeting, wrapper forming, quantitative filling, and siomai shaping. Once the dough and filling are prepared and loaded into the hoppers, one operator can manage the machine during production.

This reduces the need for manual wrapper preparation and individual filling operations.

Multi-Roller Dough Sheeting for Uniform Wrappers

The multi-roller pressing system gradually processes the dough into sheets. It helps maintain consistent wrapper thickness and provides a more uniform appearance for the finished siomai.

The wrapper thickness and size can be adjusted according to the customer’s product specifications.

Accurate Filling Portioning

The filling system controls the amount of filling dispensed into each wrapper. Customers can adjust the filling quantity according to the required product weight and wrapper-to-filling ratio.

This helps produce siomai with more consistent weights and filling distribution.

Adjustable Product Specifications

Different markets and food businesses may require different siomai sizes. The siomai making machine allows adjustments to wrapper thickness, wrapper size, and filling quantity.

The finished product weight can also vary depending on the machine model and customized configuration.

Easy Cleaning and Maintenance

• The material hopper features a detachable design for convenient cleaning.
• The support frame uses PE material, making disassembly and cleaning easier.
• The machine body is made of stainless steel for food processing applications.

The dough moisture content is approximately 28%, depending on the dough formulation and processing requirements.

4. What Types of Siomai Can This Machine Produce?

The automatic siomai making machine can be configured for different siomai recipes. Two common product types are meat siomai and glutinous rice siomai.

Meat Siomai

Meat siomai typically uses minced pork, beef, or other meat fillings. Depending on the recipe, customers can also add vegetables, mushrooms, shrimp, and seasonings.

The filling quantity and wrapper specifications can be adjusted to achieve the desired finished product weight.

Glutinous Rice Siomai

Glutinous rice siomai uses cooked or prepared sticky rice as the main filling ingredient. It can also contain diced meat, mushrooms, and other ingredients.

For fillings containing larger particles, we recommend confirming the ingredient size and recipe before selecting the machine configuration. This helps us evaluate the suitability of the filling system and provide an appropriate solution.

5. Customized Siomai Production Solutions

Not all customers produce the same type of siomai. Differences in recipes, product weights, wrapper sizes, and filling ingredients can affect machine configuration.

To recommend the right automatic siomai making machine, we need to confirm the following details:

1. Siomai Type: Do you produce meat siomai or glutinous rice siomai?
2. Finished Product Weight: How many grams does each siomai weigh?
3. Wrapper-to-Filling Ratio: How much dough wrapper and filling are required for each piece?
4. Product Shape and Size: What shape and dimensions do you want for the finished siomai?
5. Filling Ingredients: If the filling contains large particles, please provide the ingredient details, particle size, and recipe.

Based on this information, we can recommend the appropriate ST-80 model and discuss customized machine settings to match your production needs.

6. Applications of the Automatic Siomai Making Machine

The series is suitable for businesses that need to produce siomai in consistent quantities and specifications.

Typical applications include:

• Frozen food processing factories
• Commercial dumpling and dim sum manufacturers
• Central kitchens and catering companies
• Restaurants and food chains
• Food wholesalers and distributors
• Ready-to-cook food manufacturers

The formed siomai can be sent to subsequent steaming, cooling, quick-freezing, and packaging processes according to the customer’s production arrangement.

7. Get a Suitable Siomai Making Solution

Choosing an automatic siomai making machine involves more than considering production capacity. The type of filling, product weight, wrapper thickness, and desired siomai shape are equally important.

Our ST-80 series includes fully automatic double-row and three-row machines, as well as a semi-automatic option. We can recommend a suitable configuration based on your actual production requirements.
