NOVELTY - Producing pelletized bio fuel, comprises: providing bio fuel feedstock; grinding the bio fuel feedstock; providing at least one gas turbine (101) configured to produce exhaust gases; contacting the exhaust gases produced by the gas turbine with the ground bio fuel feedstock to produce a dried material having a moisture content less than the feedstock; and pelletizing the dried material.    USE - The methods are useful for: producing pelletized bio fuel; producing drywall; producing dry powder pharmaceuticals; producing the food product; and modifying an existing manufacturing facility that includes a dehydration unit (all claimed).    ADVANTAGE - The gas turbine generator dehydrates high water content feedstock efficiently and economically by providing both electric power for use or sale and heat for processing the feedstock. The closed contact between the gas turbine exhaust and dryer vessel: is effective in absorbing and muffling the gas turbine exhaust noise; and is significant in lowering or eliminating the emission of nitrogen oxides, sulfur oxides, carbon monoxide or carbon dioxide into the atmosphere and adding the nitrogen, sulfur and carbon components to the nutrient value of the product produced by the process.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) producing drywall comprising: providing a core mixture material including mineral gypsum; placing the core mixture material between two layers or paper; compacting the core mixture material between the two layers of paper to produce a compacted material; providing at least one gas turbine configured to produce exhaust gases; and contacting the exhaust gases produced by the gas turbine with the compacted material to produce a dried material having a moisture content less than the compacted material;    (2) producing dry powder pharmaceuticals comprising: providing a mixture of active ingredients of a medicinal drug and additives; granulating the mixture; screening the granulated mixture to produce a deposit; providing the gas turbine; and contacting the exhaust gases produced by the gas turbine with the deposit to produce a dried material having a moisture content less than the deposit;    (3) producing a food product comprising: providing a raw food feedstock; providing the gas turbine; contacting the exhaust gases produced by the gas turbine with the feedstock to produce a dried material having a moisture content less than the feedstock; and at least partially frying the dried material in oil; and    (4) modifying an existing manufacturing facility that includes a dehydration unit, comprising replacing the existing dehydration unit with a gas turbine system (10) including the gas turbine configured to produce exhaust gases and the dryer vessel (200) adapted to receive the exhaust gases from the gas turbine through the connection.
