Applications: There are several terms used for steam.
- Process steam is used in process applications as a source of energy for process heating, pressure control and mechanical drives.
- Culinary steam can be direct injected during food processing. Culinary steam needs to meet 3-A Culinary Standards for the dairy industry.
- Process steam does not generally come in contact with the final product whereas culinary steam can, and often does, come in direct contact with the final product.
