Cleaning E-cigarette Manufacturing Equipment

Q: We are manufacturing e-cigarettes and need to find a good cleaner for our equipment.  We are removing residues of essential oils, glycerin and flavor enhancers with an automated clean-in-place.  Our tank is 500 gallons.  We are unsure how much cleaner we need.  Can you at Alconox Inc. help?

A:  The oily residues in e-cigarettes (vape) you describe can certainly be a challenge to remove and make cleaning e-cigarette manufacturing equipment a challenge.

A good rule of thumb we use is you need about 10% of the overall tank volume as cleaning solution to properly Clean-In-Place (CIP).  In this case about 50 gallons of solution.  To make a 2% Solujet® Low-Foaming Phosphate-Free Liquid solution, use one gallon in 50 gallons of wash water. Use the hottest practical temperature, 160-180 deg F (70-80 deg C) would be ideal.  It is best practice to have that initial rinse be of equal or elevated temperature as well.  This is to avoid thermal shock to any micelles that have formed and the risk of redepositing the removed residue.

Higher concentrations of Solujet detergent can be brought to bear if there is a high amount of oil residue.  Concentration relates to detergent capacity, or the amount of residue that can be carried away.
