My apologies for not providing enough detail.
We are a carbonated soft drink manufacture.
We produce syrup ( treated water, flavorings, sweetener and acidulants, preservatives and other ingredients). This syrup is blended in our mixing room in tanks with agitation. This syrup is highly concentrated and then is blended with treated water and injected with carbon dioxide and chilled on a blending station which is in a separate room.
The mixing room is a separate room and currently does not contain a heat source, it does have a cooling source. We are located in the Northeastern U.S.
I could not find any SQF requirements regarding a heat source for a food mixing room.
