Powder Mixer Selection Considerations

Aug. 20, 21

A growing challenge for the powder handling industry is to accommodate a wide portfolio of formulations and a large number of different ingredients, some of which pose an allergen risk. Some companies are willing to spend a lot of money to install the highest speed mixers and packaging lines to achieve high efficiency and throughput. But just because powder blender equipment is high-speed does not necessarily mean it offers the best process solution.

 

Whether you are a beginner or a seasoned professional, choosing a mixer from the wide range of available options can be confusing and overwhelming. This article presents some questions to consider during the mixer selection process.


After installing the mixing bin, the HTD series column bin mixer will complete all the actions automatically such as lifting, mixing, and descending. An automatically-lifting bin mixer and several mixing bins of different specifications can meet the mixing requirements of diversified varieties and different batches of products. It is an ideal machine for mixing in pharmaceutical plants. It is also widely used in such industries as medicine, chemical industry, food, etc.

Batch production or continuous production?

The most important decision to make before choosing is whether to produce in batches or continuously. Will the process require periodic recipe changes or will it produce the same product day in and day out? If no changes are required, then it makes sense to consider continuous processing with large stationary powder mixing equipment coupled to upstream and downstream processes.

 

However, many manufacturers are finding that consumer desire for more variety is leading to more recipes being added to an ever-expanding product portfolio. The result is more recipe variations than ever before. This leads to the need to double-check how the mix is made. In this case, batching is the only way to go.

1. Batch size

For mixers, bigger is not necessarily better. The dry powder blender may be large enough to match the order quantity and batch size, but be aware of the loading time. Consider how long it takes to rip and dump a 25 kg bag of ingredients to fill. Then consider how long it will take to empty the product into the package. During this time, the mixer will be idle and inefficient. Companies often do not realize the cost of time lost in filling and emptying the mixer but should consider the waste it represents.

 

Also, consider if there are different batch size requirements. Does the customer always want the same size order? Is it necessary to produce half or a quarter of a large batch in small quantities? If there is a lot of variabilities, consider mixing with a medium-sized bulk container system (IBC), which can accommodate different sized containers in a single powder blending machine.

 

2. Powder characteristics

Free-flowing powders with similar composition particle sizes will mix readily. More gentle mixing methods will work well here, such as tumbling mixing or ribbon mixing.

On the other hand, in order to uniformly mix sticky powders that are viscous, the material needs to be processed to force the particles to fold and bind. In this case, a mixer that provides high shear in the form of a tool or enhancer is required. Applying the right amount of shear is critical to get the particles to engage and mix with each other, however, if not managed properly, particle degradation and heat buildup may occur.
