The "best" blender (or mixer) for a dry bulk material application is determined by considering all of these design factors:
• The abrasiveness of the product
• The fragility of the product
• Density disparities and particle size range of the ingredients
• Preventing or dispersing agglomerates
• The desired batch volume
• The required total output
• The frequency and degree of cleaning
• Cross contamination concerns
• Bacterial contamination concerns
• CIP and subsequent drying
• Heating or cooling requirement
• Vacuum rating, for degassing or capture of VOCs
• Pressure rating, for inerting or reaction
• Materials of construction: mild steel, stainless, or other alloys
• Surface finish required: industrial, sanitary for food, sanitary for pharma
