70 to 150 kg batch of dry fruits and multi-grains, a Vertical Screw Mixer (also known as a Conical Screw Mixer or Nauta Mixer) is the industry standard.

Unlike horizontal ribbon blenders, the vertical screw is much gentler, which is critical for dry fruits (almonds, cashews, raisins) to prevent them from breaking or losing their natural shape during the mixing process.

2. Why it’s Ideal for Dry Fruits & Grains

• Low Shear Mixing: The screw rotates on its own axis while orbiting the perimeter of the cone.³ This lifts the material gently from the bottom to the top without "crushing" fragile dry fruits.
• Total Discharge: Because of the conical shape, 100% of the material is discharged from the bottom. This prevents "cross-contamination" when switching between different grain mixes.⁴
• Space Efficient: Vertical mixers take up significantly less floor space than horizontal mixers of the same capacity.⁵
• Easy to Clean: The interior has no "dead corners," making it easy to sanitize between batches of salted, roasted, or raw dry fruits.

Pro-Tip for Multi-Grain Mixing

If your mix includes very fine powders (like masala or salt) along with heavy grains and dry fruits, ensure the mixer has an Orbiting Arm. This ensures that the fine powder doesn't just sit at the bottom but is evenly distributed throughout the batch in less than 10–15 minutes.
