Steam still has an important role to play in jacketed heating, but a Direct Steam Injection (DSI) Heater provides the most precise and energy-efficient method for heating the jacket water to the desired temperature.
Customers have many choices for heating water, liquids or slurries, but Direct Steam Injection (DSI) Heaters should be at the top of the list of options for these challenging applications.
The most common method of transferring energy with steam is indirect heat exchange, which has a significant drawback. Due to the pressure drop as the condensate exits the trap, some portion is inevitably lost to flash evaporation. As the condensate is lost, system efficiency is impacted. There is an alternative method that is ideal for high-pressure systems: direct steam injection (DSI) which achieves 100% heat transfer efficiency.
The challenges of heating fluids and providing a steady hot water supply are important to a wide range of industry types, and there are many solutions that engineers employ to meet those challenges. Not all solutions are equal, however; following a selection path designed to save up-front costs may not always be the best strategy. There are numerous factors to consider, including ones that may be less obvious.
The limits to indirect heat exchange examined in Part 1 become more significant as greater temperature or pressure is required for heat and hot water applications. In many cases, the solution for design engineers is to opt instead for direct steam injection (DSI).
If your cooking process is still relying on traditional batch cooking methods, it may be time to rethink what’s possible. With a Pick Sanitary Heater/Jet Cooker, food and beverage manufacturers can unlock the power of continuous cooking using direct steam injection, an innovative approach that delivers rapid, uniform heating, reduces energy costs, and streamlines maintenance.
