McLanahan Corporation – Bedding Dryer


About the Company:

McLanahan Corporation provides complete manure management solutions for the agricultural industry. McLanahan’s custom engineered systems help dairies minimize the challenges of manure handling with safer, simpler and smarter solutions.

About the Solution:

Used for both sand and manure bedding, McLanahan’s Bedding Dryers greatly improve the quality of your dairy’s bedding. By partnering with long time drying expert Uzelac Industries, McLanahan is bringing years of drying knowledge to the dairy industry.Drier bedding means that less moisture is being brought into the barns and stalls. This provides less opportunity for bacteria to grow and a healthier environment for cows. It also means less handling and stockpiling of the bedding source since it can and should be used immediately following its discharge from the Bedding Dryer.

High temperatures in the system quickly and efficiently reduce moisture and kill pathogens that lead to poor cow health and low milk quality. The result is cleaner, drier bedding that can be reused almost instantly. In the barns, the free stalls are cleaner and more comfortable, ultimately resulting in healthier cows with higher milk production and lower somatic cell counts. Multiple sizes and many options are available to suit almost any drying need.

McLanahan Bedding Dryer systems are designed for quick, easy installation with minimal costs. Simply mount some ductwork and collectors, hook up electricity, connect the energy source for heat, and you’re ready to make cleaner, dryer bedding.

Operation of the drying system requires minimal operator interaction. Exhaust temperatures are monitored, helping to indicate the dryness of the material. Once a target exit temperature is established and set, the system automatically adjusts to maintain that desired exit temperature, ensuring a consistent final product. To feed the system, a hopper supplies material at a constant rate to the dryer. The system at the exit conveys the finished product to the desired storage location. The finished product will be ready for bedding with no further handling required.

Systems are designed and built for optimal thermal efficiency to keep operational costs as low as possible. Bedding material is retained in the dryer just long enough to remove moisture and achieve maximum pathogen kill before exiting the system.

The drying system is flexible and can operate on Natural Gas, Propane, Diesel, or on Biogas produced from anaerobic digestion.

Solution Strengths, Weaknesses and Critical Indicators

Active Drying Technologies:

  • Produce a marketable product, dry manure solids, and reduce transportation costs
  • Require energy to reduce water content and dry manure solids, purchased energy cost are an issue
  • Require operator attention in excess of other systems due to the risk of combustion
  • Other compounds are released with the water (i.e. ammonia, hydrogen sulfide), and require additional treatment
  • Potential loss of ammonia nitrogen due to volatilization
  • Proven technology for storage reduction, odor control, GHG reduction and pathogen reduction

Newtrient Comments/Opinions:

McLanahan Corporation Agricultural Divisions' core product is its sand-manure separator (SMS). Over 100 SMS have been installed on dairy farms in the US since becoming commercially available in 1997.  The new McLanahan bedding dryer system can be used with the SMS or with the McLanahan rotary fiber recovery system to produce drier and more hygienic bedding. The system is designed and engineered to the same high standards as the other products of the McLanahan line and the partnership with Uzelac Industries insures that this system has a proven support system behind it.

McLanahan is in the process of introducing this technology to the dairy industry and Newtrient is aware of two installations at this time, one on sand and one on digested manure solids. Newtrient will continue to work with McLanahan to establish a 9-Point Score and to refine the cost and performance information as additional commercial dairy installations come on line.
