Slug assessment

  Uncategorized

During the wash cycle count the number of slugs entering the receiver.

The aim is to have 12-15 well-formed slugs entering the receiver during the wash cycle, at a speed of between 7 and 10 m/s

Slug speed can be estimated by following this method:
1. Determine the time, in seconds, from when the air injector turns on to when the slug enters the receiver.
2. Calculate the entire length of the milk line in metres.
3. Divide the length by the time to get the speed i.e. metres/second.

Example: A 25-unit herringbone with a looped milk line.
Time taken from when the air injector first turns on to when the slug entered the receiver is 4.1s.
The entire length of the milk line is 40 m.
