What Equipment Is Used In Distillation

Distillation is the process that involves the conversion of a liquid into a vapor that condenses back to liquid form. Non-volatile solids separate from liquids through Purification. Laboratories use the Purification method to separate mixtures based on different conditions to change the phase of components of the mixture. We heat the liquid to force components that have different boiling points into the gas phase. There are many Distillation Equipment

To perform distillation there is apparatus used for the process. Let’s take deep down to gather more information about the equipment.

Pot Stills:

Pot stills are preferably used for making whiskey or rum. It works on a batch Purification basis. They are traditionally constructed from copper. Pot stills consist of different components that include the bottom part. We call it a kettle that we heat from the bottom, boils off the alcohol, and allows the vapors to go to a condenser and separate. We use pot stills to make aged and crafted spirits. It is a flavorful Purification device. 

Column Stills:

The other name of the column still is continuous or Coffey still. Column stills are of stainless stills. It comprises a tall column structure attached above the top of the boiling kettle designed to attain purer vapors. This column design still allows for deriving pure alcohol directly from the ferment. These stills come in use for industrial and mass commercial alcohol production. 

It divides into chambers using perforated plates. This should be heated at the bottom, so while pouring the ferment from the cooler top part and when it hits the stream, it vaporizes and sends the alcohol back to the top.

Practical Uses Of Distillation:

Scientific uses-
Laboratory uses distillation. Chemical and pharmaceutical research regularly uses the distillation process. This comes in use for quality assurance testing for many consumer products and law enforcement forensics. 

Water purification-
Water contains a variety of minerals plus impurities. Purification removes the impurities present in the water. We use distilled water in situations where the presence of minerals might reduce the effectiveness of types of equipment like stem iron or cigar humidors. Distillation plants use this method to turn seawater into drinking water.

Alcoholic beverages-
Alcoholic beverages like whisky and rum are produced through the process of Purification. When we ferment the fruit and plant materials, it produces the diluted version of ethyl alcohol. Other components and alcohol are also obtained with this process. 

Petroleum products-
We get many products from crude oil. As all products have unique boiling points, it is known as fractional Purification. It is used to refine oil into separate materials. These consist of gasoline, diesel fuel, lubricating oil, fuel oil, etc. 

The earliest use of distillation is to make perfume. This process extracts essential oils that contain the aroma of various plants and herbs.

There are various kinds of distillation-

  1. Simple
  2. steam
  3. Vacuum
  4. Fractional
  5. Zone
  6. Air-sensitive vacuum
  7. Short path

Types of distillation for effective processing:

Regardless hundreds of years of chemical study have resulted in several distillation methods. Each one has an operational advantage in terms of efficiency or a unique mode of operation for a certain chemical. The following examples, however, provide illustrations for each Purification apparatus technique.

Simple Distillation-

The device separates distinct liquids based on their boiling point temperatures throughout this operation. The only way this approach can distinguish the substances is if their boiling temperatures are noticeably different from one another.

Likewise, fractional distillation separates two liquids more effectively than simple distillation when their boiling points are near to one another. Similar Distillation Equipment is used, but the vapors enter a fractional distillation column, which has a substance with a large surface area that facilitates condensation.

Vacuum Distillation

The boiling point of the majority of liquids decreases as pressure decreases. Vacuum Purification requires nearly zero pressure and requires liquids to boil at lower temperatures than normal. As a result, the distillation process operates more effectively and might potentially use less energy due to the reduced heat. Vacuum Purification avoids high temperatures and enables more effective processing of liquids that degrade with heat.


Vacuum distillation and this process have a close relationship. After dissolving a material in water or another solvent, it would be frozen. Without heating or melting, a vacuum converts the ice to vapor and removes the solid, dry residue. The preparation and packing of food involve the employment of microbes and other biological elements and components that are frozen.

To sum up:

Distillation is the process in which water vapors convert into volatile liquids and separate through selective boiling.  There are many companies providing distillation services in the USA. ‘Alaqua Machinery’ is the best distillation equipment supplier in the USA.
