I just completed an experiment that aims to filter the trub out of the cooled wort before it goes into the fermenter without clogging the strainer/filter at the fermenter mouth. The reason I had to come up with this technique was I still cant whirlpool effectively
.
The result was zero lumps of trub going into the fermenter and only very few traces of material in the strainer. Only fine cloudy stuff got into the fermenter which Im guessing is the cold break, yeast and fine hop powder from the pellets.
Essentially, once the cooled wort had been given 30mins to settle, I placed a steel colander into a nylon grain bag and slowly lowered it into the kettle. The steel colander needs to be just small enough to fit into the kettle. The kettle was then allowed to settle for a further 20mins.
I believe the key here is the weight of the colander made it act as a press that lightly but continually squeezed the clearer beer through the filter into the colander without letting in any larger material. The filtered beer in the colander would also settle further before being siphoned from the centre of the colander. Some trubby wort did get pushed up the sides between the kettle and the bag but as the level of wort fell from the siphoning, clearer beer would also filter through from the sides (although didn't contribute too much).
Here it is in pictures.
The wort in the kettle after cooling and settling for 30mins:

Lowering the sanitized colander and filter bag into the kettle (slowly):

Colander at bottom of kettle and clearish beer entering the kettle centre:

After syphoning, the beer left at bottom is still clear of any large material:

This is the only material on the strainer at the mouth of the fermenter!
