Integrated Equipment Solutions for Roasted Coffee, Concentrates & Instant Coffee Production
LENO TANK provides a complete range of hygienic and precision equipment for the industrial-scale processing of coffee, from green bean handling and roasting to the production of liquid concentrates, ready-to-drink (RTD) beverages, and instant coffee powder. Our systems are engineered to preserve delicate coffee aromatics, ensure extraction efficiency, and deliver consistent quality in both craft and high-volume production environments.
Core Processing Stages & LENO TANK Equipment Integration:
| Production Stage | Critical Process Requirement | Recommended LENO TANK Equipment | Key Value & Advantage |
|---|---|---|---|
| 1. Green Bean Handling & Cleaning | Sorting, cleaning, and temporary storage of green coffee beans. | Vibrating Screens, Air Separators, Silo Tanks | Sanitary conveying and storage systems prevent contamination and allow for controlled, batch-wise feeding to downstream roasters. |
| 2. Roasting & Cooling | Applying controlled heat to develop flavor and aroma, followed by rapid quenching to stop the process. | Indirect Heat Exchangers, Cooling Conveyors, Cyclones | Thermal oil or steam-based heat exchangers provide precise, indirect heating for roasting applications. Rapid cooling systems lock in flavor profiles. |
| 3. Grinding | Reducing roasted beans to a consistent particle size optimal for the chosen extraction method. | Precision Grinders with Nitrogen Inerting | Closed-loop grinding systems minimize oxygen exposure and volatile aroma loss. Particle size consistency ensures uniform extraction. |
| 4. Extraction & Brewing (Liquid Products) | Efficiently solubilizing coffee solids and aromatics from grounds using hot water under controlled conditions. | Multi-Stage Extraction Columns, Diffusion Batteries, Plate Heat Exchangers | Counter-current extraction columns maximize yield and concentration. Plate heat exchangers precisely control brewing water temperature and cool the extract immediately to preserve freshness. |
| 5. Concentration & Aroma Recovery | Removing water from the coffee extract to create a concentrated liquid or syrup, while capturing and re-incorporating volatile aromas. | Vacuum Evaporation Systems, Aroma Recovery Units | Low-temperature vacuum evaporators concentrate coffee solids without heat damage. Integrated aroma recovery columns capture top notes and add them back to the final product, a critical step for premium quality. |
| 6. Drying (Instant Coffee) | Transforming liquid coffee concentrate into soluble powder via spray drying or freeze drying. | Spray Dryers, High-Pressure Homogenizers | Spray dryers with integrated high-pressure homogenizers create a fine, stable emulsion feed for drying, resulting in instant powder with superior solubility, color, and aroma retention. |
| 7. Mixing & Product Formulation | Blending concentrates, sweeteners, dairy bases, or flavors for RTD coffee drinks. | High-Shear Mixers, Jacketed Blending Tanks | High-shear mixing ensures stable emulsions for milk- or cream-based drinks. Jacketed tanks provide precise temperature control for mixing and holding. |
| 8. Filling & Packaging | Aseptically or hot-filling the final liquid product, or packaging instant powder. | Sanitary Pumps, Aseptic Filling Systems, CIP/SIP Systems | Sanitary lobe/piston pumps handle viscous concentrates. Mobile CIP systems ensure hygiene for multi-product lines. Aseptic technology enables ambient shelf-stable RTD products. |
Why Choose LENO TANK’s Coffee Processing Solution?
Preservation of Critical Quality Attributes: Our low-temperature evaporation and closed-loop aroma recovery technologies are specifically designed to protect the volatile compounds that define coffee’s premium taste and aroma, which are easily lost in traditional processing.
Maximized Yield & Efficiency: Multi-stage counter-current extraction achieves higher soluble solid yields from the same amount of coffee grounds compared to batch methods, directly improving your raw material utilization and cost efficiency.
Flexibility Across Product Formats: One integrated platform can be configured to produce multiple high-value products: premium roasted beans, liquid coffee concentrates (for cafes), shelf-stable RTD beverages, and high-quality instant coffee powder. This future-proofs your investment.
Hygiene & Cleanability: All product-contact surfaces are AISI 316L Stainless Steel with electropolished finishes. Systems are designed for full CIP (Clean-in-Place), eliminating coffee oil residues that can become rancid and cause cross-contamination of flavors between batches.
