Commercial Burner
A high-capacity, low-emission Maxon® burner is standard on BROCK BCT Commercial Tower Dryers. The commercial-grade burner features a cast aluminum manifold to help reduce orifice corrosion and maintenance. Brock’s unique application of centrifugal fans allows the square burner to be mounted in a square duct and provides uniform airflow across the complete burner surface for efficient combustion and even heat mixing. The generous length of duct above the burner further enhances the temperature balance from the top to the bottom of the heat plenum.
Maxon trademark is not owned or licensed by CTB and is the sole property of its respective owner.
Double-Wide, Double-Inlet Centrifugal Fans
Double-wide, double-inlet (DWDI) centrifugal fans were an easy first choice for the BROCK BCT Dryers because they deliver more air while using less horsepower. This method of delivery promotes uniform, efficient movement of heated air. The twin-fan unit also offers easy access to motors for servicing as needed.
Unobstructed Grain Columns
Fresh air along with electrical conduits and gas piping enter at the bottom of the dryer and not through the grain columns. This promotes even grain flow and efficient drying. Air inlet louvers are adjustable to control the volume of cool air entering the dryer.
Variable Width Grain Column
A narrower width column is employed at the top of the dryer to help increase the air flow on the wettest grain to start the drying process sooner.
Stainless Steel Screens
Stainless steel screen perforations are used in two sizes .078 and .062 inch (1.98 and 1.58 mm) to help confine particulates for cleaner dryer operation.
Self-Cleaning Plenum Floor
Brock’s unique, self-cleaning heat plenum floor minimizes particulate accumulation by recirculating it back into the grain for safe operation and reduced cleaning maintenance.
Brock’s advanced Circular Drag Grain Unloading System (patented) evenly meters the grain from the grain columns and gently delivers it to the unloading point at the perimeter of the dryer.
Easy Access and Service
Ample clearance under the dryer offers easy walk-through access and generous space for auxiliary equipment.
Commercial Plumbing
Commercial block and bleed gas train is standard with high and low gas safety switches.
Brock’s advanced INTUI-DRY® Dryer Controller is standard and automatically regulates the drying process.
With the TrueGrain™ Moisture Sensor System from Brock, grain is diverted through a vertical chamber at a constant speed using a metering wheel. This uniform sensing area prevents fines and condensation from accumulating which could distort measurements.
