ROTARY ELECTRICAL CONTROLLED DRUM DRYER FOR ORGANIC FERTILIZER PRODUCTION

There is one of many unresolved issues in agriculture production and it is the fertilization issue. The long-term non-organic fertilizer availability with reasonable price will determine the national agriculture production sustainability, which it will also guarantee the national food resilience. Since the fertilizer is an essential need for agricultural growth, in the 60s the goverment gave the subsidized fertilizer. While in fact, the stocks continue to decline over time.

The implementation of this research uses several methods, functional and structural method that depends on each stage of work. In the first year, it was focused on design and manufacture of the machine, so that it creates a truly efficient and effective machine. Next, the functional and structural method was used for the selection of the right components and materials. It would produce an efficient machine for producing the organic fertilizer. Afterwards, performance test and economic analysis were done.

The technical evaluation that will be held is intended for:

- Identifying the physical characteristics (segregation) from organic fertilizer before it enters the machine and product at the outlet of the machine. - Determining the capacity and drying efficiency. The time needed for drying until the mixture is dried with the determined water content. - Knowing the number of labours, types of work, operational convenience and technical problem that appear while operation. - Determining the engine power for production process to determine the optimal engine power for the procedure. - Calculating the noise level while production process and give the recommendation for the operator while operating the machine.
