Introduction
John Milstead is a notable inventor based in Chattanooga, TN (US). He has made significant contributions to the field of engineering, particularly in the area of drying technology. With a total of 10 patents to his name, Milstead has developed innovative solutions that address environmental concerns and improve operational efficiency.
Latest Patents
One of his latest patents is the "Dryer drum coater having vented outer shell for VOC/NOx reduction." This invention focuses on reducing blue smoke emissions by evacuating the blue smoke from the dryer drum coater independently of the exhaust of combustion products. The blue smoke, produced when heated and dried aggregate is mixed with other asphaltic products, is evacuated from a vapor outlet formed remote from the exhaust products outlet. This innovative approach prevents the introduction of excess oxygen into the combustion zone of the dryer drum coater, enhancing overall efficiency.
Another significant patent is the "Rotary drum dryer having aggregate cooled shielding flights and method." This rotary drum dryer features devices for cooling shielding flights located in the combustion zone of the drum. The cooling flights rotate with the drum, scooping up virgin aggregate and showering it over the shielding flights, thereby cooling them without substantially decreasing the mean temperature of the aggregate. This design limits the showering of materials into the burner flame, inhibiting emissions and improving the system's efficiency.
