The unit consists of two cylinders arranged in a "V" shape with an angle of 80°. A manually actuated inspection and loading port is provided at the end of each cylinder, allowing access to its interior. The product outlet is located at the point where the two cylinders are joined and is fitted with a manually or automatically actuated butterfly valve. The geared motor and the bearing system are located within the lateral supports holding the blender body.
The solids are introduced into the blender through the loading aperture. The mixing performance is of 50%, that is, with each turn of the blender, the product located in the two cylinders moves into the central common section, and this is repeated continuously. The speed is not high, which makes this unit especially suitable for products that need to be
maintained cold.
The mixture is discharged through a hermetically closing butterfly valve which can be operated manually or automatically.
The unit is provided with a guard rail with electrical safety to prevent the operator from accessing it when in operation. If anyone should gain access to the unit, for safety reasons, the operation will cease.

Blending is crucial for the big organizations that are in the manufacturing of medicines, food, and agricultural products. Various blending equipment is available in the market that can help. V mixer and ribbon blenders are on top. These machines make the blending of materials quite efficient.

However, most companies get confused about selecting the right machine for their use. It could be possible that one machine is not suitable for two different tasks in the firm. Therefore, it is vital to think carefully before buying a blending machine.

Undoubtedly, both V blenders and ribbon mixers work excellently. So, let's know more about them and see the key things that make them different from one another.

V Blender

                                                       

V blender is a mixing equipment that perfectly handles dry mixing in an orderly manner. It can be used to combine different dry powder and granular ingredients in the culinary, chemical, and pharmaceutical sectors.

The mixer has the qualities of a straightforward structure, easy use, and an attractive look. Stainless steel, which complies with CGMP, is used for the portions that come into touch with the materials.

1) Working Principle

The working principle of the V blender is simple and effective. A motor and speed reducer are installed on the right side of the equipment. The motor of this machine is responsible for driving the speed reducer with the help of a belt.

The reducer tends to drive the mixing cylinder in the V shape. It will work via a coupling process. Therefore, the powder content available in the V-shaped cylinder gets mixed. During the mix, the motion that is being followed in the machine is back and forth. The motion is in all directions in the cylinder.

2) Machine Structure

The V-Blender, the double cone, and the slant cone are the three most common designs for tumble blenders. The powder in a rotating jar in a tumble blender cascades due to the influence of gravity. One of the most popular tumbling blenders is the V-Blender, usually referred to as a twin-shell blender.

Many other family members have closely followed this blender's blending performance. They enable quick and effective blending at the same time. As for the v blender parts, the two hollow cylindrical shells linked at an angle of between 75° and 90° make up the V-Blender. Trunnions support the blender container to enable it to tumble.

Ribbon Mixer

                                                     

What is a ribbon mixer? A ribbon mixer is a light-duty blender mostly used for pre-processed powder ingredients. The content is simple to mix, such as dry granules and pre-sieved powders. It is a SOLID/SOLID mixer that is mostly used for mixing.

The ribbon mixer is the most adaptable and popular kind of powder blending machine on the market. They can be employed for applications that involve coating a dry particle with a liquid ingredient. Besides, particle absorption of any liquid addition. However, they are frequently used for mixing solids on solids.

1) Working Principle

How does a ribbon blender work? Powder blenders with two pieces fixed on a central shaft are known as Ribbon Mixers. Inner and outer helical ribbons intended to move material inward and outward frequently make up the mixing medium.

The internal ribbons push the product back to the sides of the mixer as the external helical ribbons pull it in from the sides. A convective mixing pattern is produced by the ingredients being folded back and forth in the motion of blending.

2) Machine Structure

Below are the pictures of the ribbon blender construction:

Main Differences: V Blender VS Ribbon Blender

1) Blending

V BLENDER

V blender can mix the powder effectively. In the pharmaceutical industry, there are many compositions that are in the powdered form. Proper mixing of the content is essential before adding the capsules. So, mixing the powdered material is extremely important. V mixer is capable of blending the powders in the right manner.  

RIBBON BLENDER

Ribbon blenders or mixers are also the right tools for mixing the powders. At the same time, they are also the perfect equipment to blend the liquid with the powder. It doesn't make lumps while mixing the liquid and powder together. Thus, it is a tool that is a great choice for blending the materials effectively. Liquid and powder mixing is not the benefit of V blenders.

2) Shape

V BLENDER

V blender is a vertical type in shape. Its structure is perfect for mixing.

RIBBON BLENDER

Unlike V blenders, ribbon blenders are a horizontal shape. They offer effective mixing with the help of their shape and design.

3) Discharge

V BLENDER

V blender has an excellent shape which helps in the complete charging and discharging of the materials. So, it offers 100% discharge of the content compared to other blender types.

RIBBON BLENDER

The ribbon blender does not offer complete discharge of the mixture. A little material will remain in the bottom of the mixer while you use it.

4) Mixture Segregation

V BLENDER

V blender is the type of blender type that can cause segregation. It might cause an issue with the proper mixing of the components in the blender.

RIBBON BLENDER

The ribbon blender offers better mixing as it avoids segregation. So, if you want the blending results without any separation of the content, pick this blender.

5) Installation Space

V BLENDER

A V blender is a machine that needs more space for installation. As the device is bigger, you will need more area to install it.

RIBBON BLENDER

However, a ribbon blender is smaller than a V blender. So, the space it will require for the installation will be lesser.
