- Thursday, December 22, 2022

In the pharmaceutical industry, there are many types of mixers, such as V cone blenders, double cone blenders,  drum blenders, ribbon blenders, etc.

If you are looking to buy a ribbon blender, we have brought a complete guideline for you where you will know about the ribbon blender advantages and disadvantages, how it works, and why pharmaceutical industries need it.

However, before digging into the details, let's know some basic things about ribbon blenders.

What is a Ribbon Blender?

What is a ribbon blender & mixer machine? The horizontal ribbon mixer is a new type of mixing and stirring equipment with high efficiency, high uniformity, high loading coefficient, low energy consumption, low pollution, and low crushing. The product has a wide range of applications and can be used for mixing and stirring powder and powder, powder and liquid, especially for mixing paste, viscous or high specific gravity materials (such as putty, real stone paint, metal powder, etc.). This equipment is currently widely used in the fields of pharmaceuticals, food, pesticides, dyes, chemicals, plastics, ceramics, coatings, putty, mortar, etc.

Ribbon Blender Advantages and Disadvantages

Besides being a budget-friendly machine, this blender has its pros and cons, which we will explain in detail.

Ribbon blending machines are powder-mixing type accessories available in the market. Industries use them for mixing solid and liquid ingredient mixing when required. In the corrective maxing pattern of the ribbon blender, you can run short and fast mixing cycles ranging from a few minutes to 15 minutes. These rapid mixing cycles make you think the ribbons move at a high RPM. However, that is not true. Ribbon agitators run up to 300 feet/min tip speed.

One can benefit from its full discharge feature if the machine has a central discharge port. By running the machine at a lower speed, one can easily push the item back and forth till the mixing vessel is empty. In addition, the manufacturers can use several powder valves on the mixer's discharge port. Whereas many plug valves can be flush with the internal surface of the mixer body when in the closed position. That preserves the buildup of the mixture during the mixing cycle.

The working volume capabilities of a ribbon mixer remain low at 30%. In case the capacity is less, it won't permit contact between the ribbons and materials. The mixer can work with 100% capacity in various applications. Whereas the ideal mixing capacity remains within 50-70.

Ribbon Blender Advantages

  •  Multi-functional

There is a never-ending list of ribbon blender benefits. One can use such versatile machinery in several industries, including food, cosmetics, agriculture, pharma, etc. Moreover, it is very easy to operate for workers looking to mix heavy ingredients easily. It is a time-saving accessory that ensures flawless outcomes within a quick time. Whether how messy the ingredients are, this machine will deliver quality results.

  •  Swift response

High shear speed ensures ingredients are mixed quickly and produces smooth output. Furthermore, the solid build of the ribbon blender guarantees no leakage of ingredients during the mixing process. As a result, one can complete the task before the given time without committing any mistakes.

  •  Durable and hygienic

Mixing different ingredients can result in contamination, leading to the transmission of hazardous material, which can adversely impact your overall health, causing infection and other diseases. The ribbon blender machine is built considering such facts and ensures excellent hygiene by avoiding products from cross-contamination. Moreover, the stainless-steel construction of this mixing machine enables It to last for years.

  •  Suitable for dry and wet users

The ribbon blender machine Adopts exquisite craftsmanship making it equally advantageous for dry and wet users. In addition, the blenders of machines are designed so that both ends are sealed.

  •  Fits easily in limited areas

The blender adopts space-saving size and easily fits limited areas. This means you don't have to arrange a dedicated area for placing your machinery to blend the industry ingredients.

  •  Produces homogenous mixture

Its double ribbon agitator moves in a counter-current motion sending material from one place to another. As a result, the manufacturers get a homogenous mixture quickly without investing too much effort.

Let's proceed with the disadvantages.

Ribbon Blender Disadvantages

  •  Not suitable for all laboratories

The blending machine does not work well in all laboratories. Therefore, you should decide about the unit as per your needs.

  •  Ribbon agitator blockage

One might experience the issue while using power's bulk density in a high concentration.

  •  It takes time to mix.

If the mixing tank of your blender is overfilled, it will require more time to mix ingredients than its normal routine.

  •  Leakage of particles

Lack of proper care can lead to broken seals, which can cause leakage of particles creating a mess for you to clear.

Principle of Operation 

How does a ribbon blender work? Ribbon mixers are powder blenders having two moving parts on a central shaft. Its mixing medium has helical ribbons inside and outside, which can move both inwards and outwards. They grab product from the sides into the middle and internal ribbons. The back-and-forth folding motion of the materials needs to be blended, forming a connective mixing pattern.

The ribbons of the machine have a distance between its walls. The manufacturers sometimes produce them with soft wipers to ensure the product keeps building up on both sides. Driving mechanism basis of a belt drive for power transmission in the motor and gearbox. It uses a system that produces speed by using flexible belts and pulleys.

Some manufacturers have started using direct drives through gears that use a motor to match the gearbox unit. As a result, machine owners do not have to worry about maintenance expenses over time. However, the owner of the ribbon blender mixer knows the needed volume of the machine.

Knowing several densities of the products to mix is important. Additionally, you should know the required mixer capacity and the need for motor power to ensure proper mixing. Often many designs produce great results with a bulk density of 35 lbs./ft³. However, when mixing the batch initiates, you need to know the requirement for heavy motors and the gear change ratio.
