To Spray Or Not To Spray, That Is The Question. The Advantages Of Using Spray Nozzles To Add Liquids Into Powders During Mixing
From pharmaceuticals & foods to chemicals & cosmetics, mixing ingredients together often requires the mixing of powders & liquids. The way we add liquid into powders during the mixing process can extend the mixing process if not done correctly. Many times you will see liquids being added by simply pouring or “dripping” them into the batch. This form is adding liquids into powder mixers is not a good practice. Droplet size or particle size of the liquid has everything to do with how the powders are affected. We want the powders to absorb the liquid, not the liquid to absorb the powder. When we simply pour ar drip the liquid in, the particle size is larger than that of the powder and what happens is the powder is drawn to the liquid and forms clumps.
By reducing the particle size and reducing the surface tension of the liquid by using spray nozzles and different pressures, we can eliminate clumping and decrease the amount of time it takes powders to absorb the liquid. The size of the powder particles will suggest what type of nozzles to use and the amount of pressure needed at the pump. The higher the pressure of the pump, the more the liquid is atomized. Several different options are available.
An additional advantage of using pumps and spray nozzles to add liquids into powders is that it optimizes the efficiency of the liquids and absorption rates, allowing you to use less liquid. It will also optimize batch control and consistency, and minimize mixing & drying times if mixing & drying.
Here is a video of our PerMix Paddle Mixer with liquid additive manifold and nozzles. The unit was equipped with a dosing pump that supplied the manifold. Not that the manifold and nozzles can be broken down with no tolls by using the Tri-Clover sanitary type clamps.

Powder Induction Mixers That Win The Hearts Of Our Customers & Perform Better Than The Competition & Beat Them On Price
Since 1954 PerMix has been leading the industry, setting the standards others follow and our PerMix Powder Induction Mixers are a testimonial of this. Our powder induction mixers take on the big brands, Ross®, Silverson®/Admix®, and others and win in regards to performance & innovation, then knock them out with our pricing.
Here is our high-shear powder induction mixer that was just rolled off our assembly line. The unit was custom built to roll up to a drum that holds the powder, fill the hopper, then close the hopper and mix into the liquid. The hopper includes a viewing port. Note that the unit can be quickly broken down to clean and maintain without the need of tools except for a wrench to remove the rotor and stator.

Nanotechnology In Pharmaceuticals Creates A Need For Advanced Mixing & Drying Solutions & PerMix Leads The Industry
Advancements in nanotechnology in the pharmaceutical industry have opened the door to new medicines and given new life to old medicines that were inefficient. Faced with so many positive aspects offered by this technology, the pharmaceutical industry has been increasingly inserting nanotechnology in its products, based on the concept that innovation moves the world.
As nanotechnology advances the pharmaceutical industry, it also advances the engineering world. A new version of old technology needs to advance, yielding highly efficient, precise, high-performance equipment & PerMix leads in mixing solutions for the nanotech industry.
So many engineering features have been advanced to create these pharmaceuticals. From mixers with jackets that allow for superheating temperatures in some circumstances that go up to 300•C and cool down to cryo temperatures, to mixers that have internal vacuum or pressure. Liquids must be added with precise control and atomized for faster absorption rates into powders. Drying of products must be precise and in some circumstances timed or staged in levels, all while recording & charting. Also, during the drying stage, vapors of solvents, reagents, and other vapors must be recovered. Finally, discharge. Discharge of products with no product loss is crucial as the product has such a high dollar value, and the formulation is so precise, product loss is a huge concern.
