Well the lunch break is not work time in Sweden so if you have a 1 hour lunch you just work longer in the afternoon. 30 minutes lunch (scheduled to fit the shifts) has been the norm when I have done blue collar work. I don't know anyone who has fika every hour. 15 minutes breakfast break and 15 minutes in the afternoon (on the clock) is normal.

You are entitled to 5 minutes (paid) break per hour worked in a shift, which the employer has the right to consolidate in various (but not endless) ways. This is on top the right to a lunch break which has separate rules. I think that both of these are is in the labour law and not allowed to substantially re-negotiated. (Many things across the various labour laws are explicitly allowed to be overridden by CBA).
