Churning
Churning is a special process that defines the process of separating butter from cream. Churning is performed manually in older days, using the traditional churner as shown in the image given below, where we take a pot full of milk cream and it fitted with a plunger, now the plunger is rotated to create agitation.
As we can see the process of manual churning is not very efficient it consumes a lot of time and labor. Thus, for processing, larger quantities this method is not very efficient. So, for processing larger quantities, the process of centrifugation is used.
In the process of churning, the plunger is rotated and the container that contains the mixture remains constant, while, in the process of centrifuge, the container containing the mixture rotates itself.
Centrifugation
Centrifugation is a technique used to separate components of a mixture based on their size, shape, viscosity and density. It works by spinning the mixture at high speed in a machine called a centrifuge, which creates a force called centrifugal force. This force pushes denser components outward, away from the centre of the centrifuge, while less dense components are pushed inward.
Key Points:
- What it does: Separates components in a mixture.
- How it works: Uses centrifugal force created by spinning the mixture at high speed.
- What separates: Based on size, shape, and density.
- Used in: Many fields like biology, chemistry, medicine, and industry.
Learn about, the churning process, centrifugation process, types of centrifugation, and others in detail in this Centrifugation Notes.
