It is one of the most frequently utilized blenders, belonging to the family of tumbling blenders. It is also called a twin-shell blender, due to its two hollow cylindrical. It has a distinctive V shape, thus the name V blender. The two angled cylinders are fused to create a V shape that has a unique role in diffusive blending.

It smoothly mixes solid-solid particles in any ratio. Moreover, it also blends solid-liquid ingredients precisely. V blender provides uniform blends of granulated, ground, and powdery materials.

2.Why V blender is so significant?

V blender is a great industrial equipment that processes up to 10 different ingredients in one cycle. It has a pivotal role in the manufacturing industry because of its unlimited benefits. This type of blender generates substantial profit margins for the industries.

Here are some common pros of V blender that boost its significance in different industries.

Homogenous Mixing

Homogenous Mixing

V blender has a characteristic V shape that makes mixing and blending easier. Its designs ensure homogenous and complete mixing. Its mixing action boosts the flowability of different particles, thereby, promoting diffusive amalgamation. This blender consistently leads to the division and combination of powdered mixture.

Gentle Handling

One of the major concerns in industries is the mixing of fragile substances. Therefore, a V blender is typically involved in the gentle handling and mixing of fragile materials because of the absence of a shaft or rotor. This results in low impact mixing force, causing minimal size reduction of particles.

Unlike other traditional blenders, the V blender ensures low-shear mixing. Hence, there is no loss of structural integrity with the V blender.

Accurate Blending

It is commonly used in the manufacturing of talcum powders, cosmetic pigments, blushes, eye shadows, and many more.

4.What is the working of the V blender?

V blender relies on gravitational force to blend the materials. The working principle behind this machine is diffusive mixing. To operate the V blender at its maximum blending efficiency, it is vital to learn about its working. Thus, we are detailing the working of the V blender for your learning.

Feeding

Feeding- Picture Courtesy: Jerónimo Martins

The raw feed is usually loaded in the V blender at the start of the operation. It is done through feed ports, located at the top of the machine. It is advised to fill the V blender with about 50-60% of its total volume. Increasing this range results in a doubling of mixing time if uniform mixing is required.

Blending

As soon as the feed materials are loaded up to the desired volume, the mixing action of the V blender begins. The entire mixing shell rotates to achieve diffusive mixing. Due to the 360° rotation of the V blender, an avalanche of materials is created. In this falling of materials, the particles are split and fused, resulting in an even blend.

The mixing is attained by random falling of materials. The ingredients constantly fall towards and away from the central point with the movement of the vessel. This random movement with frictional force between the feed and walls of the V blender results in a consistent but delicate mixture.

Discharging

Finally, the blended mixture is discharged from the vent fitted with a butterfly valve. This port is found at the bottom of fused shells. The opening of the butterfly valve is either controlled manually using a hand lever or automatically using pneumatic controls.

5.What is the structure of a V blender?

This machine is composed of twin mixing vessels or barrels that are connected mutually at the angle of 70-90° to create a V shape. There is a huge assortment of parts in the V blender. These components act together to ensure that every blending batch has precision and consistency.

Some fundamental parts that have an essential role in blending are penned below:

Parts of V Blender

Inspection Port	This vent along with the feed port is enclosed by cover to maintain the blend integrity. There are different types of inlet covers such as the ones that are secured by the safety pin and those that are locked by the clamp rings. This port aids in cleaning, checking, and maintaining the machine.
Intensifying Bar	It is the optional component present in some versions of V blender. It is fixed on the rotational axis of the equipment and functions as a lump breaker. The intensifying bar also plays a part in breaking large agglomerates. It offers adequate shear for reducing chunks.
Feed Port	This is the feeding inlet from which raw feed is poured into the machine. It is located at the top of the V shell. The inlets are hermetically sealed to maintain a dust-free environment.
Trunnion	It is a cylindrical structure that provides stability and support to the mixing vessel. It bears the whole weight of the equipment and allows the vessel to rotate.
Mixing Vessel	It is a V-shaped vessel and is one of the most critical components of the machine. The actual blending process happens in the mixing vessel. The rotation of the mixing vessel is essential in the cascading of materials that in turn causes the mixing of feed. This part is fitted with intensifying bars, spray nozzles, jackets, and vacuum systems for increased mixing efficiency.
Safety Guard	It is a cage-like structure and is a fundamental safety feature. Its function is to safeguard operators from dangers during the machine's working. Some dangers include rotating parts and sparks.
Discharge Port	It is the vent from where blended materials are removed from the V blender. It is situated at the bottom part of the equipment, where two shells are joined. For optimal efficiency, the discharge ports are equipped with a butterfly valve that prevents material wastage.
Alarm Light	It is a detector that functions as a visual indicator by blinking light to notify the operators of abnormalities in the working of the V blender. It is an important tool from a safety perspective, as it helps decrease the risk of accidents.
Control Panel	It typically provides a platform for starting and stopping the machine. It is the main programming component of the machine that regulates the functionalities of the V blender. It is customized with different buttons and sensors to optimize the programming performance.
