How to clean beer lines with Maxi-Enzyme
- Firstly, read the SDS and the detailed ‘Safe Operating Procedure’ (SOP).
- Turn off the glycol system.
- Connect required beer lines to the wash out line.
- We recommend flushing out remaining beer in the system with water, this allows the new chemical to be attacking the biofilm on the wall linings and not the beer itself; and it helps to reduce the temperature of the beer font. Maxi-Enzyme is most effective when font is closer to ambient temperature.
- Connect line from siphoning pump to the wash out line. Smaller
venues can simply connect a drop lead from the ‘siphon spear’ to the wash out line, the system’s FloJet beer pumps will siphon. - Fill ‘wheely bin’ (or suitable container) with sufficient 50°C hot water add dilution as indicated on the label.
- Open beer taps and continue until the liquid is light blue (see below), we recommend using a small bar glass for reference. Keep the taps open until the colour blue is the same as in the container in the coolroom. Maxi-Enzyme changes colour when it is working and removing contaminants, we wish to rest the once the ‘easy to remove’ dirt has been removed.
- Once all the lines are full of Maxi-Enzyme, begin 60 minutes rest.
- We recommend checking all taps to ensure full of Maxi-Enzyme.
- After 60 minutes rest (longer is ok), disconnect the line from the siphoning pump and connect the water (potable).
- Flush the lines minimum 4 x line volume, for example if line holds 3L, then flush minimum 12L of water through the line.
- Maxi-Enzyme once activated is pH9.2, so pH test strips can be used.
- Reconnect all beer lines to their respective beer kegs.
- Open the taps until beer reaches the taps, stop at first sign of foam.
- We recommend checking all taps to ensure full of beer.
- Turn on the glycol pump on the glycol chiller unit.
