Seed Drying Features

• STS chamber dryers are designed and engineered for precision of temperature, humidity and air flow for drying all varieties of seed.
• Seed drying must be as versatile as possible. Yet, the products' temperature, humidity and air flow have to be accurate. If they are not, under drying or over drying can occur. The STS dryers are designed to provide this accuracy.
• The STS dryer cabinet/chamber models trap air and humidity with precise calibrated temperature and discharge them at a given rate based on seed density and seed moisture content.
• The operator has the control to increase or decrease the amount of air velocity in the front portion of the dryer plenum. This control allows the operator to increase or discharge excess amounts of air as needed with regards to drying load capacity.
• Each drying box or chamber has its own damper adjustment. Either to balance air velocity or close off a section.
• Each drying box or chamber section can be calibrated with air velocity different from the other damper section or chambers at anytime.
• The STS electric and gas model heating units are both versatile in air flow to provide a more detailed velocity requirement. The Gas Model, however, uses speed control motors and bleeder dampers to adjust air speed and pressure.

Seed Dryer Heating Components

1. Modulating Controller - Gas Models

   STS Dryer systems use a modulating controller to keep the temperature band as tight (narrow) as possible to eliminate heat swing.

   The modulating controller senses the temperature of the discharged air and proportions the gas input to load demand. When the temperature is below the controller setting, the burner will modulate to high fire. As the air temperature approaches the controller setting the modulating gas valve will close in small increments until the control point temperature is maintained. As the discharge air temperature falls below the control point setting, a reverse cycle takes place opening the modulating gas valve trying to maintain at least a 3-50F heat swing. Again, as tight of a heat band as possible is maintained.

2. Electric Models

   All electric model heating units are versatile to heat settings. Our electric air flow is calibrated by a variable speed controller Also available is a motor switch control for two speed setting. The heat is controlled by staggering heat elements to keep a consistency of calibrated heat throughout the drying regime. This is to provide a gentle cycle at all times. The dryer can keep temperature consistent to 1 degree heat swing with mild (tight band) heat swing cycling.
