Modes of Mixing
Modes of Mixing – Batch and Continuous Mixing
- All raw materials charged together or in a predefined sequence i.e All the materials are first charged into the mixer, they are run for a specific amount of time, then after the mixing is completed the batch is discharged and the next batch is taken.
- It is mixed until homogeneity
- Output is measured in kg/batch. Though it is measured in kg/batch, the mixer is always defined or designed for volumetric capacity. And for mixer specification, it has to be specified in terms of working volumetric capacity.
Batch mixing is preferred for applications where:
- Production quantities are small
- Strict control of mix composition is required, typically in pharmaceutical industry or food industry.
- Many formulations are produced on the same production line
- Ingredient properties change over time and compensation must be on a batch-by-batch basis
- It is required to identify a batch for further follow up, example – pharmaceutical formulations, food products.
- Material flows steadily from an upstream process into the mixer
- Material is mixed as it moves from the charging point to the discharge point
- The time that material is retained in the mixer is known as the retention time
- Weighing, loading, mixing and discharge steps occur continuously and simultaneously
- Output is measured in kg/hr
Continuous mixing is preferred for applications where:
- Large quantities of a single product are to be mixed
- In a continuous process line requiring high production rate
- Strict batch integrity is not critical
- Smoothing out batch product variations is required
