Appearing at regular intervals, unhinged idealisers (10)

I believe the answer is:

serialised

I'm a little stuck... Click here to teach me more about this clue!

'appearing at regular intervals unhinged' is the definition.
I can't tell whether this definition defines the answer.

'idealisers' is the wordplay.
'idealisers' can be anagrammed to 'SERIALISED'.
Though, I'm not sure how this is indicated.

Can you help me to learn more?

(Another definition for serialised that I've seen is " shown in several parts".)

I've seen this clue in The Everyman puzzle in The Observer.
