PerMix Vertical Ribbon Mixers

PerMix Engineering Team Presents: Ribbon Mixers Designed For Small Spaces

PerMix has been leading the industry with our engineering & innovation since 1954. We set the standards others follow.

Recently we have been featuring our horizontal ribbon mixers, the type that is most common. PerMix also has created a vertical ribbon mixer that gives you all the standard features of a horizontal ribbon mixer, along with some added features & benefits, that make it quickly becoming one of the most popular units.

Horizontal ribbon mixers, of all brands, leave residue inside the mixing chamber upon discharge. This is typically between 5-10% of the volume mixed. The creates not only a cleaning issue but also impacts the bottom line when it comes to increasing profit margins. The vertical ribbon mixers greatly reduce this issue, using gravity along with the vertical cone design to discharge almost 100% of the product, with a residue typically of only 0.5%-1%. This not only saves cleaning time but also increases the profit margins.

Horizontal ribbon mixers also require a minimum of a 20-30% minimum fill capacity to have an efficient mixing action. This greatly effects the units flexibility when it comes to batch sizes and the ability to run small batches when needed. The vertical ribbon mixer’s minimal batch size is typically 5% of capacity, allowing it to be more flexible in production runs that are smaller, a perfect fit for co-packers.

Horizontal mixers, due to their U-shaped trough, when it comes to heating & chilling, have less surface area for proper & efficient heat transfer. Vertical ribbon mixers have a more efficient conical design that allows for a greater surface area for heat transfer, making it more efficient when it comes to heating or drying, decreasing batch times and increasing production & profits.

Horizontal mixers require a larger amount of floor space when compared to vertical ribbon mixers. This greatly benefits the end-user in several ways from allowing for smaller footprint in the processing line, which allows for the need for less real estate, saving money in regards to leasing/purchasing production area space.

These are just a couple of advantages when we compare horizontal ribbon mixers to vertical ribbon mixers, there are many more advantages not listed. For more information, contact your local PerMix office to discover the PerMix difference.

Here is an example of our PerMix PVRD Vertical Vacuum Ribbon Mixer that includes a polished interior, internal vacuum, ASME heating/cooling jacket, and inert gas injection.

PerMix Engineering Team Presents: Selecting The Right Configuration Of Ribbon Mixers

A ribbon mixer consists of a U-shaped horizontal trough and an agitator made of inner and outer helical ribbons which move them radially as well as axially. Blending time is usually less and mix quality is also good. In principle, a ribbon mixer requires very little maintenance.

Ribbon Mixer selection and specification:
One should take care of the sizing parameters as well as features that can be changed according to the need of your operation. Main thing is to define the entire process in detail so that one can arrive at the best model. Another parameter to take into considerations are volume required – which helps in arriving at proper size of the mixer, bulk density – which helps in determining how much dense the material is and whether the mixer will be suitable for that application or not.

Some of the common problems faced during ribbon blender processes are mentioned below, along with the solution.

Powder Blending – Batch processing is the most common ribbon blender operation. Mixing of spices, tablet formulations, chemical additives, powdered flavorings, baking mixes, etc. are some of the examples of mixing process which can be done in a ribbon mixer. Mixing process typically gets over within 15-20 minutes. Depending on the material characteristics of the powder in your batch’s recipe some of the optional features such as dust discharge valve are worth considering.

Particle Coating – Another frequent use of ribbon blender is to coat the smaller particles onto the particles with the higher size. As the particles sizes are different, close tolerances must be provided between the ribbon blades and trough which eliminates the dead zone present in the mixer. Another thing to be kept in mind is how the minor ingredient is added and at what time, cause it also affects the quality of the mix.

Vacuum drying ­– Another common operation that can be performed on ribbon blender is drying of the powders. The combination of reduced pressure and constant stirring accelerates the drying even at nominal temperatures. This process is ideally suited for the heat-sensitive material prone to thermal degradation when exposed to high temperatures.

Mixing solids of different particle shapes and sizes – In this situation, the different components in a mixture vary in size, shape and density. Achieving a thorough blend must often be balanced with minimizing damage to the more delicate ingredients. Fast and gentle mixing in a ribbon blender is a suitable method for preparing the blend.


PerMix Explosion Proof Mixers

PerMix Engineering Team Presents: Sanitary Mixing In Explosive Atmospheres – PerMix Explosion Proof Mixers Lead The Industry

Powders present a unique problem sometimes, creating an explosive atmosphere as sometimes ingredients have properties that have UEL, LOL, & flashpoints, creating hazardous atmospheres & work environments. No one understands the need to create a safe & sanitary mixing environment in these conditions than PerMix.

PerMix Explosion Proof Mixers are available in capacities ranging from 1 liter to 30,000 liters, PerMix engineers products that not only meet sanitary conditions but also have an Ex rating. Our ASME-certified jackets allow for the ability to not only heat but also cool, creating precise temperature control & monitoring, allowing users to stay within explosive limits, as well as monitor for chemical reactions sometimes that might take place while mixing, and avoiding them. Also, PerMix can include internal vacuum, which removes air from the mixing chamber, eliminating the one thing needed, oxygen.
