HTX GRAIN HEATER

DESCRIPTION

The HTX Grain Heater is designed for controlled temperature increase of free-flowing cereal grains.

Grain is conveyed into the heater via the inlet hopper, where it passes by a series of vertical heating plates. As the Grain flows through the plates, heat is conducted from the plate surfaces to the grain. Temperature increases of up to 70° F (21° C) are possible.

The HTX Grain Heater is very flexible because of its modular design and its automatic or manual controls.  The machine can be mounted above or through the floor.  Steam, super heated water, or even thermal oil systems can be used as the heating medium.  There is also an optional feed-back control system that can continuously monitor and maintain the target set point temperature and product retention time.  All of these features make for easy training, use, and maintenance.

THE SYSTEM

The Optional Control System continuously monitors and maintains a constant product level above the plates, based on the incoming rate of feed. In cases where thermal oil or hot water is used as a heating medium, the target set-point temperature will also be maintained.

Temperature is regulated by steam pressure (in the case of high pressure steam) or by a hot fluid mixing valve. The valve position is determined by the product discharge temperature. The inlet temperature is also displayed for reference.

Product retention time is maintained by a continuous level control system. An inlet hopper sensor determines the variable position of the discharge slide gate. As the product level varies above or below a preset target, the slide gate will open or close proportionally. This, along with a mass-flow discharge design, ensures a constant retention time within the heating area, and a smooth discharge flow equivalent to the incoming flow.

The optional control panel is housed in a NEMA 4 enclosure with front panel operator controls. The continuous digital displays include target discharge temperature, actual inlet and discharge temperatures, gate position, and inlet product level.  Remote communication is possible with existing PLC’s.  Manual back up controls are built into the panel.
