Factors Influencing Selection:

• Product characteristics (e.g., viscosity, particle size, reactivity)
• Desired degree of mixing and uniformity
• Production capacity and batch size requirements
• Equipment availability and cost

3. What are the common challenges faced in mixing operations and how would you overcome them?

Some common challenges in mixing operations include:

• Achieving uniform mixing and avoiding segregation of ingredients.
• Controlling mixing time and energy input to avoid overmixing or undermixing.
• Preventing cross-contamination between different products or batches.

To overcome these challenges, I would implement the following strategies:

• Selecting the appropriate mixing equipment and process based on product characteristics and mixing requirements.
• Optimizing mixing parameters (e.g., speed, time, temperature) through experimentation and data analysis.
• Implementing rigorous cleaning and sanitation procedures to prevent cross-contamination.

4. How do you ensure the quality of mixed products?

To ensure the quality of mixed products, I would implement a comprehensive quality assurance program that includes:

• Establishing and maintaining clear quality standards and specifications for mixed products.
