System Process Flow

1. Feed Hopper with Bar Screen

We understand that not all manures are created equal, and that the consistency of the manure, the arrangement of the feed systems, and the intended beneficial reuse will drive the selection of the material handling equipment. More InfoVulcan® Drying Systems provides best in class manure feed handling options for clumpy, lumpy, sticky and just plain trashy feed. We know how to handle it all.

2 Feed Conveyor

After passing through the feed hopper with bar screen, manure is transported up the feed conveyor, prior to being dried in the rotary drum More InfoVulcan® Drying Systems Systems utilizes Tuffman® Conveyors in order to provide state-of-the-art conveyors for each system manufactured in our facility.

3. Rotary Drum Dryer

The work horse of the Vulcan® Drying Systems Manure Dryer System is the heavy duty, low temp, direct heating, rotary drum dryer. More InfoThe low temp dryer is extremely energy efficient and can be configured to utilize a variety of fuels or waste heat to perform the drying process. Our single pass system is a simple low cost method of producing a granular fertilizer. For a highly marketable product, our blending, dosing, and recirculation system produces a high value fertilizer pellet. Systems are available as stationary plants or built on a mobile platform.

4. Material Discharge

On discharge, all processed manure is sent to the client mandated location for re-purposing and re-sale. More InfoHowever, the Vulcan® Drying Systems Systems Manure Dryer doesn’t stop there. This system ensures that all particulate matter is removed in a safe and secure fashion

5. Cyclone

Processing manure is not without its stink. Fortunately, the included Vulcan® Drying Systems Air Pollution Control (APC) equipment removes particulate and abates the odor. More InfoFor manure with high levels of ammonia or a super powerful odor, our multistage condensing and dosing systems ensure that the stink is limited to the sweet smells of success.

6. Venturi Scrubber

After particulate and vapors are passed through the system, the Vulcan® Drying Systems Venturi Scrubber provides a secondary precaution to help remove ammonia and particulate matter from vapors. More InfoVulcan® Drying Systems Systems takes environmental control and regulations very seriously, seen through our use of Venturi Scrubber technology in all of our manure drying systems.

The Versatility of Vulcan® Drying Systems Rotary Dryers

REMOVE MOISTURE FROM A WIDE VARIETY OF MATERIALS, LEADING TO RE-SALE AND RE-PURPOSING.

PARALLEL AND COUNTER-CURRENT FLOW

The flow of the rotary dryer will determine how a material dries while passing through the system. In dryers with a parallel flow configuration (also referred to as ‘co-current’), hot gases enter the system alongside the wet material. This allows the material to come into quick contact with the hot gases at a high temperature, resulting in rapid evaporation of moisture. In dryers with a counter-current flow configuration, the hot gases enter the dryer on the end opposite the materials, allowing the material to come into contact with the gases at the highest temperature when already dry. Parallel flow dryers are often used for materials with a high moisture content, while counter-current are typically used for materials with a low moisture content.

SUITABLE FOR A VARIETY OF MATERIALS

Vulcan Rotary Dryers are equipped with flights, specifically designed in each unit to maximize the transfer of heat from the hot gas stream to the material being processed. Whether the material is fertilizer, minerals, industrial waste, coarse, or fine, the moisture content can be reduced to the needed percentage in order to fulfill the client’s need. Minerals, coal, and animal feeds will typically have a high moisture content and need to be processed in higher temperatures, whereas chemicals, salts, sugars, and pigments should be dried at lower temperatures in order to avoid the overheating of the material.

Learn More About Animal Manure Drying

While thermal drying can be used to treat a large variety of materials, thermal drying is commonly used to remove highly volatile contaminants from swine, bovine, and poultry manure. Animal manure drying is one great example of how Vulcan® Drying Systems technology is unique in the industry. Our equipment is able to reduce or eliminate disposal costs, reduce the volume of manure, sequester odors, such as ammonia, and produce a marketable dry pellet fertilizer.
