Designed for high-efficiency, uniform mixing of high-viscosity meat fillings, vegetable mixed fillings, dumpling/bun/samosa fillings, and various seasoning sauces. Equipped with 30L to 60L capacity stainless steel barrels, a bottom quick-discharge valve, and a multi-power speed system, it perfectly replicates the flavor absorption and binding texture of hand-stirred fillings while significantly reducing labor and time costs—making it the ideal choice for large-scale, standardized filling processing with a high return on investment (ROI).

I. Product Overview

1. Basic Equipment Information

  • Equipment Name: Commercial Vertical Stuffing Mixer / Sauce Mixing Tank (Commercial Vertical Stuffing & Sauce Mixer)
  • Product Models: MI Series (Includes MI-30 / MI-40 / MI-50 / MI-60)
  • Model Naming Convention:
  • MI: Mixer / Vertical Stuffing & Sauce Mixer
  • Number Series: Represents the capacity of the mixing bucket (e.g., MI-30 represents 30L capacity, MI-60 represents 60L high-capacity specification).
  • Equipment Positioning: Specially engineered for medium-to-large pastry factories, dumpling/bun/samosa forming workshops, central kitchens of chain restaurants, and sauce processing plants. It is an industrial-grade food processing machine integrating high-efficiency stuffing mixing, sauce blending, and liquid seasoning formulation.

Exterior & Technical Crafting Standards:

  • Industrial Standardization: Features a top-mounted heavy-duty motor drive combined with vertical agitator shaft technology, simulating multi-angle manual mixing trajectories. This ensures 100% dead-zone-free mixing of meat, vegetables, and seasonings, promoting rapid protein extraction and binding without destroying vegetable fiber textures.
  • Bottom Quick Discharge & Anti-Splash Design: Equipped with a food-grade quick-release discharge valve at the bottom (with a red handle). After mixing, there is no need to manually tilt or scoop out the product; simply open the valve to discharge directly into containers. The top is fitted with a fully enclosed stainless steel safety guard mesh and splash cover to maintain a clean workplace.
  • Heavy-Duty Power & Voltage Adaptability: Equipped with powerful 1500W to 4000W motors (2HP - 5.3HP), supporting 220V single-phase and 380V three-phase customization, delivering stable torque according to various material viscosities (thin sauces, vegetable-meat fillings, heavy meat pastes).

2. Mixing & Stuffing Process Flow

The MI Series Commercial Vertical Stuffing Mixer overcomes the bottlenecks of labor-intensive manual mixing and difficult unloading found in traditional horizontal mixers by adopting industry-leading vertical agitator shaft technology and bottom-split discharge systems.

  • Industrial Multi-Blade Paddle: Standardized with a food-grade 304 stainless steel multi-blade paddle that combines blending, kneading, and homogenizing functions to ensure meat fibers absorb water and seasonings evenly.
  • One-Step High-Efficiency Blending: Pour diced meat, chopped vegetables, sauces, and spices into the food-grade stainless steel mixing bowl, lock the protective lid, and start the machine. It achieves rapid protein binding or uniform vegetable mixing in a short time, giving the final product a juicy, tender texture.

3. Core Positioning: Why Choose Automatic Vertical Stuffing Equipment?

For pastry factories and central kitchens with high capacity demands, commercial vertical stuffing equipment is an essential tool to achieve capacity leaps and standardization:

  • Revolutionary Labor Replacement: Automates the entire process from meat-vegetable blending to high-viscosity meat binding. A single operator can process tens to hundreds of kilograms of ingredients, completely replacing strenuous manual mixing.
  • High Capacity & Efficiency: Bowl capacities reach up to 60L (MI-60 model), with a single batch output of up to 2-90kg, easily meeting the continuous feeding requirements of forming production lines.
  • Full-Process Standardization: Controlled speed via high-performance motors eliminates quality, taste, and seasoning fluctuations caused by inconsistent manual mixing effort, ensuring batch-to-batch product consistency.
  • Effortless Bottom Discharge: The unique bottom valve discharge design drastically reduces unloading time, lowers operator labor intensity, and accelerates workshop turnover.

Manual / Standard Horizontal Mixer vs. MI Series Commercial Vertical Stuffing Mixer

Feature Manual / Standard Horizontal Mixer MI Series Commercial Vertical Stuffing Mixer
Batch Capacity 5L - 20L 30L - 60L (Up to 60L with MI-60)
Discharge Method Manual scooping / tilting bowl (laborious) Bottom valve direct discharge (time & labor saving)

Material & Structure Standard metal / simple welds Food-grade 304 stainless steel / heavy chassis with casters
Target Users Small eateries, street stalls Large pastry plants, central kitchens, forming lines

4. Processing Compatibility & Customization Limits (Important Note)

  • Material Compatibility: Supports pork, beef, lamb, chicken, vegetable mixtures, bean paste, thick sauces, and liquid seasoning marinades. For high-viscosity heavy meat pastes, operation within the rated batch capacity (2kg-90kg) is recommended.
  • Capacity & Specification Limits: Bowl capacities are fixed at 30L-60L. Do not exceed the maximum stuffing capacity of each model to prevent overload. Special custom agitator blades can be ordered separately.
  • Facility Requirements: Users must provide a stable 220V / 380V (or custom 110V upon request) power supply adaptable to local voltage standards.

5. Core Structure, Hygiene & Waterproof Details

To meet the strict hygiene, cleaning, and durability standards of modern food factories and central kitchens, the MI Series has undergone professional upgrades:

  • Wiring & Drive Protection: The top motor and electrical control circuits are enclosed in sealed covers and heavy-duty protective conduit, offering excellent waterproof, moisture-proof, and oil-resistant properties to prevent short circuits in humid washdown environments.
  • Food-Contact Parts 100% 304 Stainless Steel: The mixing bowl, agitator shaft, blades, and bottom valve are made of premium food-grade 304 stainless steel. The material is corrosion-resistant, rust-free, and can be washed directly with water without hygiene dead spots.
  • Enclosed Safety Guard & Cooling Motor: Fitted with a safety guard mesh featuring a micro-switch to enhance operational safety. Built-in 4-fan high-efficiency cooling system ensures the motor does not overheat under continuous heavy-load operation, extending equipment lifespan.

II. Production Process & Standard Operating Procedure (SOP)

The following core operation and parameter setting guide is summarized from actual machine commissioning and operation:

1. Equipment Inspection & Preparation

  • Check the power cord and grounding protection to ensure stable voltage (220V/380V), and lock the caster brakes.
  • Verify that the bottom discharge valve (red handle valve) is fully closed and locked.
  • Install the stainless steel agitator shaft and blades properly, ensuring all fasteners are secured.

2. Material Loading & Speed Selection

  • Material Loading: Pour diced meat, chopped vegetables, water, and seasonings into the bowl, taking care not to exceed the maximum rated capacity (e.g., MI-30 output limit 20kg, MI-60 output limit 90kg).
  • Start Operation: Close the top stainless steel safety guard mesh, press the start button, and begin mixing.

3. Process Monitoring & Discharge

  • Observe the mixing status. When the meat filling reaches uniform water absorption and binding, or when the vegetable filling is evenly mixed, press the stop button.
  • Position a receiving container (such as a filling pan or trolley bucket) directly beneath the bottom discharge valve, open the red handle valve, and the material will rapidly discharge assisted by gravity and mixing motion.

4. Emergency Stop & Safety Protection

  • A prominent red Emergency Stop Button is located on the control panel. In an emergency, pressing this button immediately cuts power to all drive systems; rotate clockwise to reset.
