Mobile Catering Ventilation Canopy Question
I'm starting a mobile catering business and I'm currently looking to buy a used trailer. I'm intending to have a double gas fryer (2x9L) and a double electric (2x5L) and I am led to believe I will need a canopy extending a certain distance beyond the frying equipment.
Can anyone provide clarity on exactly what is needed in terms of a ventilation canopy? (I understand there is a further requirement of 25sq cm per kW of fixed ventilation).
Would we need a commercial extraction system? Could this be a DIY job with some sheets of stainless of the right dimensions, in order to get the natural draught?
Any further help greatly appreciated1
