TÜV Rheinland CE certified · 5 minutes per batch · High-efficiency mixing with full flavor retention

1. Project Background

In Italy, manufacturers of flavored food powders, essential-oil-based blends and functional nutrition powders place very high demands on both flavor retention and mixing efficiency.
Traditional general-purpose mixers often struggle in this application:

• Essential oils are not evenly dispersed – some particles are overly “oily”, while others have almost no aroma;

• Long mixing times cause batch-to-batch variation and limit throughput;

• Open or poorly sealed designs promote aroma loss and make cleaning more difficult.

This Italian customer wanted to upgrade to a mixer dedicated to “powder with essential oil addition”, and clearly specified:

The mixer must be CE certified by TÜV Rheinland, achieve about 5 minutes per batch, and maximize retention of essential oil flavor and activity while delivering high efficiency.

2. Customer Profile & Application

Customer type:
An Italian food and nutrition manufacturer producing:

• Instant drink powders containing essential oils (lemon, orange, herbal flavors, etc.);

• Flavored bakery premixes and compound spice blends;

• Functional solid beverages where essential oils are combined with nutrients as key value points.

Application characteristics:

• Essential oils are added at low dosage but have a huge impact, so they must be very evenly dispersed in the powder;

• The mixing process must stay gentle, with low temperature rise, to avoid evaporation and degradation of aromatic and active components;

• Multiple batches per day with frequent recipe changes, so short batch time and quick cleaning/changeover are critical.

3. Our Solution (Configuration & Process Features)

After fully understanding the formulation system (carrier powders + essential oils + minor ingredients) and the plant’s hygiene standards, we supplied:

A high-efficiency essential oil powder mixer
TÜV Rheinland CE certified, achieving one batch in about 5 minutes.

(1) TÜV Rheinland CE-Certified Safety & Compliance

• The mixer has passed CE certification by TÜV Rheinland, complying with EU Machinery Directive and relevant electrical safety standards;

• Safety guards, emergency stops and interlocks are all integrated, making it easier for the customer to meet internal EHS requirements and third-party audits.

(2) Mixing Structure Optimized for “Powder + Essential Oil”

• The mixing element provides a combination of intensive powder tumbling and gentle shear, helping the essential oil form a thin, even coating on powder particles instead of creating oily lumps;

• Internal flow patterns have been engineered so that target homogeneity is reached in about 5 minutes per batch, significantly increasing line productivity;

• All product-contact surfaces are polished to reduce essential oil residue and build-up.

(3) Flavor Retention & Volatility Control

• The mixing chamber uses a semi-closed / closed design to minimize aroma escape during mixing;

• The mixer operates with controlled intensity and time to avoid unnecessary frictional heating, better preserving natural aroma and active components in the essential oils;

• Well-suited for temperature- and oxidation-sensitive oils, such as citrus and delicate herbal essential oils.

5. Initial Customer Feedback

After installation and commissioning at the Italian plant, the customer reported very positive results during trial and early production:

1. More uniform essential oil distribution and stable flavor

   • Finished powders show much more consistent aroma intensity and taste across batches;

   • Downstream customers and internal QA both confirm that “flavor is more stable and predictable.”

2. 5-minute batches significantly boost capacity

   • While maintaining the required quality, the mixing cycle has been shortened from well over ten minutes to about 5 minutes per batch, clearly increasing throughput;

   • This gives the customer more flexibility to handle peak orders and manage multiple SKUs.

3. Reduced aroma loss and better product perception

   • Noticeable aroma “escape” in the production room has been reduced;

   • Finished products now present a stronger, more focused aroma on opening, helping to elevate the perceived quality of the brand.

6. Conclusion

This high-efficiency essential oil powder mixer exported to Italy, CE certified by TÜV Rheinland, successfully combines in one machine:

• Gentle handling that protects essential oil flavor and active compounds;

• High efficiency with around 5 minutes per batch;

• Full compliance with EU safety and hygiene requirements.

For European food and nutrition manufacturers who need to add essential oils into powders and who care about both high productivity and premium flavor, this type of “high-efficiency + gentle processing” dedicated mixer is an ideal solution to upgrade product quality and production performance.
