Abstract

The new space-planning solutions are proposed that allowed transferring a tower-type grain dryer from gas to liquid fuel while maintaining the recovery of cooling air and partial recovery of the dryer agent from the lower part of the drying zone. In this case, the drying zone is divided into upper and lower zones by a partition, and the mixing chamber is separated from the cooling zone by a partition and connected with the upper drying zone by an air pipe. This position of the mixing chamber allows recovering both the exhaust cooling air and the dryer agent delivering them into the upper drying zone together with the fresh dryer agent. In this case, the heat generator is removed from the air-pressure chamber of the grain dryer and can run on liquid or any other type of fuel. Based on the developed design model, the heat and aerodynamic calculations of the grain dryer were carried out as well as the sizes of drying zones, costs and air filtration rates for the productivity of 15 t/h with a decrease of humidity by 5% (from 19% to 14%). It was established that due to the recovery of cooling air and dryer agent the fuel economy up to 31% can be achieved. The engineering documentation is developed, a tower-type grain dryer is assembled, installed and tested at one of the grain-producing enterprises of the agricultural complex
