Design a system for drying a product $($choose one from the list found in Food and Foodstuff $-$ Specific Heat $($engineeringtoolbox website$))$ with the following constraints and requirements

The system has to have a capacity to deliver $10,000$ kg$/$hr of material with $5\%$ moisture from a feed containing $300\%$ moisture.

The dryer efficiency must not be lower than $65\%.$

The system must not emit toxic gasses to the atmosphere.

The system takes air from the atmosphere $($measure the actual atmospheric condition in AdU on the time of computation. Show proof.$)$

Specify the appropriate size of fan and heater. Refer to the internet for specific brand and cost.

Try at least five different computation; create a technical and economic comparison then recommend the best option.
