ENERGY INTEGRATION OF CORN COB IN THE PROCESS OF DRYING THE CORN SEEDS

ABSTRACT
A greater contribution energy production in the future should be expected from agricultural biomass, because current research indicates low utilization of agricultural biomass specifically in the direct combustion process. The paper presents an example of energy integration of the corn cob in the process of drying seed corn. The paper presents the efficient method of drying corn seed with one’s own corn cob. The technological process of drying is presented through the technological process of operation of the corn seed dryer on the corn cob, the energy industrial plant of the dryer and the technological process of two-pass drying of the cob. The main characteristic of a given dryer is the process of two-pass drying of the cob, because the air passes through the cob layer twice and in that way energy is saved. The drying time on the presented dryer has been shortened from the usual time from 90-80 hours, i.e. by 11%. This increase in performance results in a 15% reduction in dryer operating costs.
