WHAT IS DIRECT STEAM INJECTION

Direct steam injection is a method of heating that mixes a precisely controlled mass flow of steam directly with water or other types of process fluids, providing an instantaneous transfer of heat from steam to fluid. Direct steam injection works by directly injecting steam into a process fluid to obtain more rapid heat transferring, resulting in more efficient energy usage than indirect heat exchangers. This method of heat transfer allows 100% thermal efficiency and energy savings of 20-25%

Direct steam injection is the most widely used method for boiler feedtank heating throughout industry. This method is often chosen because of its simplicity. No heat transfer surface or steam trap set is required, and there is no need to consider the condensate return system.

ONE STEP FORWARD : STEAM INFUSION

  1. What is Steam Infusion? – Steam Infusion is a direct-contact heating process in which steam condenses on the surface of a pumpable food product. Its primary use is for the gentle and rapid heating of a variety of food ingredients and products.
  2. Why to choose Steam Infusion? Unlike steam injection and traditional vesselled steam heating; the steam infusion process surrounds the liquid food product with steam as opposed to passing steam through the liquid. Steam Infusion allows food product to be cooked, mixed and pumped within a single unit, often removing the need for multiple stages of processing.

STEAM INFUSION ADVANTAGES VS. STEAM INJECTION:

  • Steam has a larger contact surface with the product – higher efficiency
  • No product overheating
  • More uniform steam temperature
  • Applicable to very heat sensitive products

APPLICATIONS >

STEAM INJECTION APPLICATIONS:

  • Pasteurization of variety of dairy products
  • Cooking of fluid-based products
  • Gentle and rapid heating of heat sensible products
