Industrial Dryer Analysis and Optimization in Energy Saving

You talking about a dryer in a laundromat, or in an "industrial" setting?

Dear Friend,

this is not a straight answer; In my company also some one is working on this. First you collect full detailed specifications of dryer present. collect data on 1. Quantity/ volume of the material being drayed. 2. Time taken for successful drying operation. 3. Total energy consumption.4. Max and Min energy requirements 4. Environmental/ ambient conditions. Now try to analyse this data and co-relate..this may help!

Refer to http://www.ttplpune.com/ Very educative site for Evaporators Incinerators Air Pollution Control Equipments Dryers & Coolers

The only way to really determine the performance of any equipment is to measure it. The parameters of interest would be Watt-Hours consumed to complete a process, with environmental measurements recorded during the process as well (ambient humidity and temperature, for example). Relying on manufacturing data can be misleading, because they do not generally provide sufficient information regarding the actual conditions under which the process was evaluated, and they are generally going to provide relatively conservative information rather than real data, to insure that variations in their product do not result in customer complaints that the equipment does not meet specs. If you are dealing with a specific manufacturer, perhaps they will share a customer list with you, and perhaps you could get other customers to measure equipment in actual operation under various conditions. Then you have real data to compare.

Yes dear,

From the language of your post it seems that you probabily have not been told by your superiors clearly what you are supposed to do and what is expected from you. No guide line are given to you only time line is given to you.

I have done my Ph.D in Large size Industrial dryers. There are issues/questions to be adressed before any one can help you.

First of all it is very important to know the kind of material to be dried in the dryer. The drying characteristics will change with the size, shape- physical form of the product. Equally important is Capicity of dryer, temperature requirement ( Min and Max temperature to which the product can be exposed), Heating Energy source(oil, gas, coal or solar), desired rate of drying, Initial and final moisture content of the product, Humidity in air at the location of dryer and many more factors.
