Stainless steel twin-shaft paddle mixer for fast, uniform batch blending of flour, premixes and compatible powders or small granules.
The Voson Stainless Steel Twin-Shaft Paddle Mixer is a horizontal batch mixer for flour, starch, premixes, food ingredients and other compatible powders or small granules. Two parallel shafts carry specially arranged paddles that lift, scatter and cross-mix material through the chamber. This coordinated movement supports rapid, uniform blending while limiting unnecessary compression of suitable ingredients.
The machine can be integrated with weighing and dosing equipment, stainless steel screw conveyors, storage bins and a flour packing machine. Chamber volume, usable batch weight, paddle layout, shaft speed, discharge system and motor are selected from the material and process requirement rather than one universal specification.
| Item | Available Configuration |

| Typical materials | Maize flour, wheat flour, starch, premixes, food powders and suitable small granules |
| Working capacity | Customized; confirmed from batch weight, bulk density and recommended fill level |
| Product-contact construction | Stainless steel; grade, thickness and surface finish confirmed before manufacture |
| Feeding | Manual, conveyor-fed or integrated with weighing and dosing equipment |
| Discharge | Large bottom outlet or other project-specific discharge arrangement |
| Controls | Batch timer, variable-frequency control, pneumatic functions and line interlocks as required |
The table gives configuration guidance, not guaranteed model data. Final capacity, motor power, shaft speed and mixing time depend on bulk density, particle size, moisture, flowability, ingredient ratio, batch weight and the required mixing test result.
Two shafts rotate in coordinated directions inside the horizontal chamber. Paddles mounted on both shafts pick up material from different zones and project it toward the center and opposite side. The overlapping trajectories repeatedly separate and recombine the ingredients, creating strong convective mixing with localized particle exchange.
With a suitable fill level and shaft speed, the moving material may form a low-density mixing zone in which particles can change position quickly. The result depends on the actual formulation, so the term “fluidized mixing” describes the movement principle and is not a guarantee of a fixed mixing time or uniformity value for every recipe.
After the validated mixing period, a large bottom discharge opening can release the batch quickly into a receiving hopper or downstream conveyor. Fast discharge helps shorten the total batch cycle, but the outlet size and receiving equipment must be selected to avoid restriction or material backup.
The internal detail shows the polished shaft, paddle support and bolted connection. Paddle quantity, angle, spacing and clearance influence circulation, energy demand and residue. Some configurations allow the paddle position or angle to be adjusted during commissioning; the exact construction is confirmed in the technical proposal.
Shaft seals separate the product chamber from the bearing and drive areas. Seal type must match powder fineness, operating temperature, cleaning method and any pressure or dust-control requirement. Regular inspection of paddle fasteners, shaft seals and clearances is part of routine maintenance.
Stainless steel construction is project-specific. Product-contact parts can be stainless steel while the motor, gearbox, bearing housings, actuator, guards and support structure may use other materials unless full stainless steel construction is stated in the quotation.
Suitability must be checked before ordering. High liquid content, sticky ingredients, highly abrasive powders, fragile inclusions or very large density differences can require a different paddle design, spray system, wear protection, seal or operating sequence. Dust explosibility, allergen control and sanitation requirements also affect the electrical and mechanical specification.
| Selection Point | Twin-Shaft Paddle Mixer | Horizontal Ribbon Mixer |
|---|---|---|
| Primary movement | Two paddle shafts lift, scatter and cross-mix material | Inner and outer ribbons circulate material axially and radially |
| Typical advantage | Rapid mixing and fast discharge for suitable powder or powder-granule recipes | Thorough circulation of many free-flowing dry powder batches |
| Material handling | Can provide relatively gentle, low-compression movement when correctly selected | Continuous ribbon movement can be effective for cohesive or uniform powder systems |
| Discharge | Often configured with a large bottom opening | Commonly uses a bottom or side discharge valve |
| Final choice | Must be based on formulation, batch size, density difference, fragility, cleaning and required test result | |
Neither design is universally better. Voson selects the mixer from material tests or verified material data and from the required batch cycle, cleaning procedure and downstream process.
Confirmed model, capacity and motor-power data are not available for this product page. The following information is therefore used for engineering selection and must not be interpreted as fixed machine specifications.
| Required Information | Selection Purpose |
|---|---|
| Material names and addition ratios | Defines the formulation and segregation risk |
| Bulk density and particle size | Converts batch weight to working volume and influences paddle design |
| Batch weight and batches per hour | Determines chamber size and required total cycle time |
| Moisture, oil or liquid addition | May require spray equipment, different seals or another mixer design |
| Fragility and allowable breakage | Influences paddle geometry and shaft speed |
| Target mixing result and test method | Provides the acceptance basis for mixing time and uniformity |
| Cleaning and allergen controls | Influences access, surface finish, seals and residue targets |
| Plant voltage and layout | Determines drive, controls and equipment connections |
Usable batch volume is lower than the empty chamber volume. Overfilling or underfilling can change the material trajectories and reduce mixing performance, so the recommended fill level must be confirmed for the selected machine and recipe.
It is a horizontal batch mixer with two parallel shafts carrying paddles. The shafts create overlapping material paths that lift, scatter and recombine ingredients throughout the chamber.
Yes, it can be selected for maize flour, wheat flour, starch, premixes and compatible food powders. The actual recipe, addition ratio and material properties must be checked first.
Twin-shaft paddle mixers are often selected for rapid batch circulation, but there is no universal mixing time. The cycle must be validated for the formulation, fill level, loading sequence and required test result.
Many powder-granule blends are possible. Particle size, density difference, fragility and segregation after discharge must be evaluated before confirming the machine.
Limited liquid addition may be possible with a correctly designed spray system. Sticky or high-moisture formulations may require different paddles, seals, drive power and cleaning access.
Please provide the formulation, bulk density, particle size, moisture, batch weight, batches per hour, target mixing result, cleaning requirements, voltage and production-line layout.
