Technical Paper Authored by Drying Expert with Assistance from James Rehkopf is Published

Pulse Combustion Systems (PCS) is pleased to announce that a Technical Paper has been published in Food and Bioprocess Technology, an International Journal. The paper is entitled “Pulse Combustion Spray Drying of Egg White: Energy Efficiency and Product Quality” and can be accessed here (

The principal author of the paper is Dr. Zhonghua Wu of the College of Mechanical Engineering, Tianjin University of Science and Technology, 1038 Dagulan road, Hexi District, Tianjin, 300222, P.R. China. PCS’s President, James Rehkopf, provided pulse-drying technical and operating information, and assisted in the drafting of the article.

“We are very pleased to see the publication of this paper in a respected journal,” said James Rehkopf. “Even more satisfying are the results of the study, which show nearly zero degradation of sensitive egg white proteins when dried in our pulse combustion spray dryer. This is in marked contrast to the damage to egg white proteins in conventional spray dryers. We appreciate Dr. Wu’s recognition of this major advantage of pulse combustion drying.”
