Distilleries are one of the largest sources of ethanol and major polluters. India alone consumes more than 2 billion liters of ethanol annually, and more efficient steam boilers are needed in distilleries. Alcohol production depends on cereals, molasses, potatoes, and other agro-products. The following steps give an overview of the process of distillation and include the importance of the steam boiler.

 

Critical Processing Steps in Distilleries

• Fermentation:

Molasses which is a residual product in sugar refining is first diluted and then mixed with yeast to initiate the fermentation process. It requires yeast reproduction in a moderated environment to get the right alcohol concentration.

• Distillation:

The fermented liquid is purified to remove other unwanted matter and then the alcoholic content is further concentrated through the process of distillation. This process involves heating diffusion and then cooling where steam boilers offer the right heat gradients.

 

Steam boilers in Distilleries

• Hot Water Supply:

Heaters are used in the boiling process to supply hot water at the appropriate temperatures required in the distillation processes.

• Preserving Flavor and Aroma:

Regulated generation of steam is important to preserve the flavors and fragrances of beverages.

• Sanitization:

Steam is used to ensure a clean environment in the distillery and to kill bacteria on the equipment.

• Controlled Heating:

Heaters help in providing constant heat to areas required for the distillation process such as boilers.

 

Some Features That Every Steam Boiler Must Have for Distilleries

• Efficiency and Reliability:

Boilers running in a continuous process have to be efficient as well as have a long life cycle.

• Low Emissions:

Boilers should avoid emitting greenhouse gases since distillery organizations produce high amounts of waste.
