Ribbon Blender, Ribbon/Paddle/Plow Blenders Machine

Operation :

The RIBBON BLENDER is an efficient and versatile blending machine for mixing of dry granules & powders homogeneously. Approximate two third of the volume of the container of ribbon Blender is filled to ensure proper mixing. The ribbon Blender gives best result for mixing of dry powder & granules due to the design and shape of the mixing ribbon and product container. It can be used for Pharmaceutical, Food, Chemical and Cosmetic products etc.

Material should be charge from the top side. There are port/ports should be provided on the top cover to charge the material as well as for air vent. One discharge valve provided at the bottom side at center of the container. The discharge height could be adjusted as per the requirement, so that material gets discharge in the other container directly, so that material handling time for discharge is nil and the operation is dust free.In ribbon Blender the powder moves from center to the end of container and end of container to the center of container. Hence requirement of total mixing time is very less and the RPM required are also very less.The dry material gets sufficient continuous movement due to the shape & movement of ribbon & shape of the container, which moves material for good quality of blending.

The unit is consist of one electrical motor, one worm reduction gear, belt drive between motor and gear, couple drive between gear to ( ribbon ) mixing stirrer. Container having four nos. of legs with discharge valve & top cover. Both end of mixing shaft is sealed with bush & PTFE gland housing & safety guards are provided on all moving parts.

SHREE BHAGWATI Ribbon Blender Overview

The SHREE BHAGWATI Ribbon Blender is a highly versatile and efficient batch-style mixer designed for blending a wide range of bulk solids and granular materials in industries like food & beverage, pharmaceuticals, chemicals, plastics, agriculture, and more. Known for its ability to handle diverse materials with ease, it is often used for mixing powders, granules, and certain slurries or pastes. Additionally, it can heat, cool, dry, or coat materials under vacuum conditions, making it suitable for a wide array of specialized mixing applications.

Key Features

1. Efficient Mixing Action

   • The ribbon blender is equipped with two helical blades (ribbons) that move in opposite directions—outer ribbons push ingredients inward while inner ribbons push them outward. This dual action ensures efficient blending by promoting both radial and axial motion of the materials, which results in homogeneous mixing and reduces the time needed for uniform distribution.

2. Batch Mixing Capacity

   • Ribbon blenders are ideal for batch processing where precise control over mixing time, temperature, and conditions is needed. The blender typically operates at a 50-70% volume capacity for optimal mixing performance. Running below this capacity may not provide sufficient material contact with the ribbons, while operating close to full capacity may lead to insufficient movement or mixing inefficiency.

3. Versatile Material Handling

   • The blender is capable of mixing a wide range of materials, including:
     • Powders and granules (spices, seasoning blends, dry mixes, pharmaceutical powders, etc.)
     • Granular materials (fertilizers, ceramics, plastics)
     • Wet applications (soups, batters, slurries, pastes)
     • Coating particles with small amounts of liquid
   • Its gentle mixing action preserves the integrity of the materials while achieving uniform distribution.

4. Discharge Mechanism

   • The centrally located discharge port allows easy and complete discharge of mixed materials. The use of plug valves on the discharge port ensures a flush, clean surface when closed, preventing material buildup and contamination during mixing cycles.
   • Low-speed operation of the mixer can help push the product back and forth to empty the vessel completely.

5. Temperature Control (Heating, Cooling, Drying)

   • Vacuum mixing: Ribbon blenders can also operate under vacuum conditions for sensitive materials that require drying or cooling under controlled conditions.
   • The heating/cooling jackets allow for precise temperature control during the mixing process, making it suitable for thermal-sensitive products or materials that need to be blended at specific temperatures.

6. Durable Construction

   • The SHREE BHAGWATI Ribbon Blender is designed for long-lasting durability. Made with robust materials, it ensures minimal maintenance and is able to handle heavy-duty mixing tasks.

How the SHREE BHAGWATI Ribbon Blender Works

• U-Shaped Horizontal Trough: The base of the blender is a U-shaped trough, where the materials are loaded for mixing. This shape facilitates effective movement and blending of materials.

• Agitator Shaft: A solid agitator shaft runs the length of the trough, supporting outer and inner helical blades (ribbons). These blades are specifically designed to push materials radially and axially, creating a motion that promotes thorough mixing.

• Helical Blades (Ribbons):

  • The outer ribbons move the materials inward, toward the center of the blender.
  • The inner ribbons move the materials out toward the blender walls.
  • This two-way axial action (inward and outward motion) is essential for achieving a uniform blend, even for materials with vastly different sizes or densities.

• Mixing Process: The radial and axial movements of the ribbons work together to create:

  • Small-scale random motion (diffusion)
  • Large-scale random motion (convection)
  • Shear forces due to particle-to-wall, particle-to-particle, and particle-to-agitator collisions, further enhancing the mixing efficiency.

• Final Discharge: Once the materials are thoroughly mixed, the product can be easily discharged through the central discharge port, which is typically equipped with a plug valve or another valve system. This ensures a clean, efficient unloading process without material buildup inside the blender.

Applications

SHREE BHAGWATI Ribbon Blenders are ideal for use in industries that process large volumes of dry, powdery, or granular materials. Common applications include:

• Food & Beverage Industry:

  • Blending spices, seasoning mixes, drink mixes, instant recipes, and powdered food products.

• Pharmaceutical Industry:

  • Mixing pharmaceutical powders, nutraceuticals, or even slurries and certain pastes.

• Chemical Industry:

  • Blending dry chemicals, polymers, and plastic compounds.

• Plastic & Polymer Manufacturing:

  • Mixing polymer powders or plastic compounds for further processing.

• Agricultural Industry:

  • Mixing fertilizers, pesticide powders, and other granular agricultural products.

• Ceramics:

  • Blending ceramic powders and other materials used in ceramic manufacturing.

Benefits of the SHREE BHAGWATI Ribbon Blender

1. High Efficiency: Ribbon blenders are designed to provide uniform mixing in a relatively short time, even for large batches.

2. Versatility: These blenders can handle a wide variety of dry powders, granules, slurries, and even wet applications, making them suitable for multiple industries.

3. Gentle Mixing: The gentle blending action reduces the chances of damaging delicate materials or creating heat-sensitive reactions, making it suitable for sensitive applications.

4. Temperature Control: The ability to heat, cool, or dry materials within the blender provides full control over the final product’s quality.

5. Easy Discharge: The design allows for full discharge of mixed materials via a centrally located discharge port, which minimizes product waste and improves efficiency.

6. Cost-Effective: Ribbon blenders are often more cost-effective compared to other mixing technologies due to their simple design, durability, and low maintenance costs.
