I would like to know how can I get Food Grade Steam (Steam suitable to be used in the food industry).

Also, I would like to know about Chemicals approved by FDA for treatment of water to be used in a boiler to produce Food Grade Steam.

Contact your boiler chemical vendor and ask them for documentation that the treatment chemicals and dosage rates are FDA/USDA approved.  If they cannot provide the documentation, or cannot supply a suitable approved chemical ~ find another vendor that understands all the criteria for your application including product liability.

How strict are the steam requirements for your application?  Can you get by with filtered steam, or do you require separate culinary steam?

Many UHT milk suppliers, for example, do not bother with culinary, and simply use carbon-filtered steam, from a boiler with USDA chemical treatment.

Do not use the steam generated from the normal boilers. Use normal steam for indirect heating in stainless steel  steam systems to generate the food quality steam. The quality of water should also be monitored accordingly. This system may be more suitable and economical for small but quality steam requirements.little low dryness factor shall also not be alarming.

Have you considered ozonating the water in any step of this process?  What's your goal in this process.

I work in a Canadian Manufactucturing facility that ships to the US, so we are subject to the FDA regulations and requirements.  My QA manager has a more intimate knowledge than I do of "Food Grade" and the discussions we have had revolve around "culinary steam".  This applies to steam that is to be applied into food directly as part of a cooking process, as opposed to food in indirect  contact (thermal vessels).

The requirement states a required filter size (I'm not sure what it is, exactly - by definition, 95% of particles 2 microns and larger must be removed) and that only stainless steel piping be used between the filter and the product.

If this is not your question, my apologies for the waste of time and space.

Food grade steam requires DI water and the process of producing the steam is in food grade equipment as you can contaminate the steam if you do not keep to spec.

Culinary steam for introduction into MILK products is well defined by 3A standards and the PMO (Pasteurized Milk Ordinance).

http://www.3-a.org/  see 609-02

http://www.wa.gov/agr/FoodAnimal/Dairy/LawsRules/1999PasteurizedMilkOrdinance.pdf   ;(just one of many sites)

I too am looking for information on requirements for direct injection into other food products and CIP solutions.

I'd like to receive technical or legal references, espeically on statements such as the DI water requirement.
