Heres something that i made up to keep hop flowers from clogging kettle pickup tube during draining to fermentor.It works a treat.Two 25cm stainless strainers ($12 each) with handles cut off ,wired together,and a hole cut in the top of one for hop additions. I have a 80l kettle and with the strainer ball sitting on the bottom of kettle,the opening sits above boil line for single batches,and i drop hops into it as i go.when i do bigger batches i have a stainless flap thta covers the opening and i raise/immerse the strainerball with a bit of stainless wire when i need to . The joys of bargain stores and chinese imports!
