A Rotary Evaporator in the Kitchen

Rotary evaporators are essential equipments for the processes of evaporation, concentration, crystallization, drying, separation, and solvent recovery in pharmaceutical, chemical and bio-pharmaceutical fields and other fields. It’s usually used to remove solvents from a mixture of compounds. Besides, rotary evaporators can be even used in people’s daily life, such as in the kitchen. In the following, let’s go through how a rotary evaporator can be used in the kitchen.

How Can a Rotary Evaporator be Used in the Kitchen?

Firstly, a rotary evaporator can be used to concentrate all kinds of juice through removing water. With a rotary evaporator, people can do it easily at home, and the juice concentrated can possess a much better taste. Secondly, several kinds of food can be extracted by a rotary evaporator as well. For example, the desired flavors can be extracted from a blend of alcohol, herbs and fruit. Thirdly, extracting brandy and syrup from wine is another using way. Fourthly, because the complex composition of food samples, proteins, fats, and sugars often cause interference in analysis and detection. Therefore, rotary evaporator is often used for treatment in advance. Last but not least, a rotary evaporator also plays an important role in the process of making coffee. As is known to all, coffee is a kind of food material that is ubiquitous in the market. It uses coffee beans and/or coffee products (ground coffee powder, coffee extract or its concentrate) as raw materials. It can add food additives without adding other food raw materials. It is a solid beverage that has been processed. In the process of making coffee, a rotary evaporator can be used to concentrate coffee by removing water from it.

What is the Principle of Rotary Evaporator?

the principle of a rotary evaporator is that the boiling points of solvents will reduce when the pressure decreases. Speaking specifically, the boiling point will decrease with reducing pressure, and increase with increasing pressure. As a result, the solvents are capable of being vaporized at much lower temperature than their boiling points at the normal pressure.

What is the Purpose of the Rotary Evaporator?

A rotary evaporator (or rotavap/rotovap) is a equipment that is used in chemical laboratories for the efficient and gentle removal of solvents from sample materials by evaporation. Besides, people can also use a rotary evaporator to separate or concentrate substances or materials.
