Explain the construction and working of silverson mixer homogenizer.
Construction
It consists of emulsified head which is covered with fine meshed stainless steel sieve.
The emulsifier head consist of a number of blades which rotates at a very high speed, to produce powerful shearing action.
The blades are rotated by using an electric motor fitted at the top.
Working:
The emulsified head is placed in the vessel containing immiscible liquid, in such a way that it should get dipped into it.
When the motor is started, the liquid is sucked through the fine holes and the oil is reduced into fine globules due to the rotation of blades.
So a fine emulsion is produced which is then expelled out.
