Continuous Flow Capacities Up to 7,000 Bushels Per Hour

Brock's continuous-flow BROCK® Commercial Tower Grain Dryer offers drying capacities ranging from 3,000 to 7,000 bushels (75 to 175 metric tons) per hour. This Brock grain dryer incorporates some of the best qualities of Brock’s proven MEYER ENERGY MISER™ Tower Grain Dryers while also adding some new features.

The new Brock commercial dryer design focuses on top quality and energy-efficient grain conditioning as well as offering user conveniences.

Features include:

  • Narrower columns at the top. A narrower width column 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) to help confine particulates for cleaner dryer operation.
  • Commercial burner. A high-capacity, low-emission Maxon® burner is standard on BROCK 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.
  • DWDI centrifugal fans. Double-wide, double-inlet (DWDI) centrifugal fans were the first choice for the BROCK Commercial Tower 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.
  • 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.
  • 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.
  • Gentle grain unloading system. 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.
  • QUANTUM® Controller. Brock's advanced QUANTUM® Dryer Controller is standard and automatically regulates the drying process.

 

Brock also offers a full line of grain storage bins/silos and accessories.

It’s been very simple to operate, and although I haven’t crunched the numbers yet, I’m sure it’s more energy efficient. It’s rated at 5,000 bushels per hour, but we’ve been getting about 5,400 with it. We liked Brock’s discharge system better than most of the competitors. There are fewer parts to keep greased and wear out, which results in less maintenance. I’d recommend the BROCK Commercial Tower Dryer to anyone who needs this type of dryer. I don’t see how Brock could’ve made it any better. It’s operated flawlessly for us, and I’m glad we went with it.

- Larry Koontz, Facility Manager, Assumption Cooperative Grain Co., Pana, Illinois

During harvest we ran it (BROCK® Commercial Tower Dryer) for 600 hours straight, and we never had a flaw or anything with it. It’s very economical to run, very energy efficient, we ran it at a higher-than-rated capacity, and we were able to integrate it very easily into our existing grain-handling system. It’s also very easy to operate – my grandmother could do it. I’d refer it to anybody. It’s the only dryer on the market, as far as I’m concerned.

- Jerry Moen, General Manager, Larson Grain Company, LaMoure, North Dakota

The price was competitive, and I really liked some of its new design features. I especially liked the way they hung the burner. It’s better as far as visibility, cleaning, and being able to work on it. It’s very accessible.

- John Husk, General Manager, Elburn Cooperative Company, Steward, Illinois

We didn’t have any problems at startup, and it’s far more energy efficient than our previous one. Our grain quality is also dramatically better out of this dryer. We can dry at much cooler temperatures to get the volume we need out of it. I really like its speed, grain quality, and efficiency. It did a very good job throughout the season with very few hiccups. At 125 feet tall, it looks cool. The farmers have started calling it a rocket.

- Mike Harmon, Location Manager, Elburn Cooperative Company, Elburn, Illinois

It was priced very competitively, and because of our experience with Brock’s MEYER Dryer, we decided to go with another Brock dryer, and we’ve been very happy with it. It’s been easy to operate, although there was a little bit of a learning curve. But Roger Frederick (Brock Grain Systems) and Ken Donsbach (Grain Masters of Bloomington, Illinois) were very good at teaching us what we needed to know. We’re very happy with it.
