Crown DTDC

crown-dtdc
Product description

Crown DTDC uses a significantly lower amount of steam and as a result, distinctly lower solvent losses owing to the unique counter-current flow as well as improvement to meal and vapour flow throughout the vessel. Fabricated vertical, multi-stage unit meal first passes through basket type pre-desolventizing trays heated by indirect steam. Exiting vapours flow around these trays at low velocity. The meal then passes from one steam-heated desolventizing tray to the next via special chutes to control the meal level.

The direct steam tray at the bottom contains a number of holes through which steam is evenly distributed in a true counter-current system. Meal then passes from one steam heated desolventizing tray to the next via special chutes to control the meal level. The direct steam tray at the bottom contains a number of holes through which steam is evenly distributed in a true counter-current system. Vapours travel upwards through special Crown Schumacher trays in the upper sections and exit via the vapour wash. A Rotary Valve (S.S. 304 vanes) is located in the last desolventizing tray and its speed is variable and controlled from a level transmitter in the upper tray thus regulating the discharge of meal to the Dryer/Cooler section.

Features
  • Automatic level control with actuated gates, chutes or variable rotary valves means less operator attention required.
  • Unique counter-current flow.
  • Low horsepower/ton requirements.
  • Heavy-duty steam chests and robust computer-designed sweep arms.
  • Basket type pre-desolventizing trays.
  • Large dome of DT for reduced dust carried out with vapours.
  • Patented vapour recovery system for even less steam use and lower solvent consumption.
