Cleaning Your EXAKT Mill

By | Pharmacy

For everyday cleaning between formulations, alcohol and a soft cloth or paper towel are the best
things to use. Do NOT spray the alcohol on the rollers or pour the alcohol into the gap when the
machine is running. Put the alcohol on a paper towel or cloth and hold it against the roller tightly
while you turn the roller with the hand wheel.

When you start to get a buildup you can use an abrasive to clean the rollers. You don’t want to do
it too often because it will remove some of the porcelain over time.

1. Do not use Ajax or Comet cleansers (even SoftScrub). They have bluing crystals that can
leave the blue dye on the roller. Find a form of SoftScrub that is made of
completely white powder. Bon Ami is another acceptable cleanser. You can find this in
big box stores with the other cleansers. Make a slurry of it with either water or Goo-Gone
(a citrus based liquid that cuts oils) and put it on the tip of a sponge and gently scour the
rollers. Other people use baking soda in light oil to do the same thing. It is possible to
put some of these slurries or Soft Scrub in the back gap and run the mill. One or two
passes will suffice. Running additional passes has the potential to create larger pores in
the porcelain.

2. Fast Orange Hand Cleaner can also be used. It can be found at retailers like Wal-Mart,
Sam’s, Home Depot, and auto parts stores. It’s a pumice based hand cleaner with the
consistency of jelly. When there is a badly stained roller, run it through the mill with the
gaps slightly open. One pass usually takes off any stain or congealed product. Do NOT
use this for more than one pass. The pumice is much more abrasive than the cleanser or
baking soda. You can put a little on a damp sponge and spot clean with it gently.
Once you’ve completed any of these steps, thoroughly clean the rollers with soap and water.
Then remove that residue with alcohol before running a new product.

Safety Warning – Many pharmacies are running back-to-back ointments and need to clean their
mills quickly. So rather than turning the rollers with the hand wheel they leave the machine running
while they clean. Not only is this unsafe for the technician, but it makes it easy to get the
cleaning cloth caught in the gap. When this happens there is a risk not only to the technician but
to the machine and its precision. It is possible to bend the shafts of the rollers if something too big
is pulled in and the repair/replacement cost can be in the thousands of dollars.

Whether you already own an EXAKT ointment mill or a mill from another manufacturer, the EXAKT 50EC+ is the best choice when considering additional mills. The EXAKT 50EC+ is a modular ointment mill, designed with removable rollers for easy, efficient cleaning. With the purchase of an extra set of rollers, you can increase efficiency in your pharmacy by having a clean set ready for your next preparation. Depending upon the product being milled, this machine produces output quantities from .02 to 7 liters per hour. Removable rollers cut down on cleaning time and cross-contamination between preparations! Remove and clean rollers with confidence! If you are processing 3-5kg at a time several times per week, or you anticipate continued growth of your topical business, you may need to consider the EXAKT 80 High Capacity or EXAKT 80E Electronic model.

The Ointment Mill Process

By | Pharmacy

An ointment mill utilizes high shear force to reduce particle sizes, disperse agglomerates, and homogenize viscous materials.  Shear force is created by three horizontally positioned rollers rotating in opposite directions and at different speeds relative to each other.  The whole product is pulled through the gap between the rollers, resulting in a precise, controllable, and narrow particle size distribution.  The particle size can be easily and precisely controlled by adjusting the gap widths.

Step by Step Process:

  1. The premixed product is placed in the hopper.
  2. The product is drawn between the feeding and center rollers and finely ground.
  3. Adhering to the bottom of the center roller the product is transported to the gap between the middle and front roller.
  4. In this gap, the product is homogenized and ground for the second time.
  5. The finished product is removed from the front roller by the scraper system.
