The lopha factory in Lam Dong built to international standards

Situated in the heart of Vietnam’s Lâm Đồng coffee region, the LOPHA factory is engineered as a modern, closed-loop production facility, where every stage of manufacturing is carried out under fully controlled conditions.

Each production zone is meticulously designed and operated to meet rigorous food safety and hygiene standards. Our entire workflow adheres to international ISO and HACCP standards while meeting FDA requirements ensuring consistency, transparency, and safety in every coffee batch.

At LOPHA, technology and standards are not used to change the nature of the coffee bean. Instead, they serve to preserve the authentic purity that nature itself has created.

Pure production process

Coffee production process using ultrasonic technology

Step 1

Raw Material Selection

Green coffee beans are meticulously selected from certified growing regions ensuring optimal ripeness, uniform bean size, and the complete exclusion of defective or substandard materials.

Step 2

Pre-Processing

Raw materials undergo preliminary cleaning to remove dust, dried husks, and foreign matter establishing a solid foundation for subsequent advanced processing stages.

Step 3

Heat Expansion (Pre-Roast Conditioning)

Coffee beans are heated under precisely controlled conditions, allowing the cellular structure to gently expand preparing the beans for physical treatments in the following step while facilitating the release of latent flavor precursors.

Step 4

Ultrasonic Treatment

Coffee beans are processed using high-frequency ultrasonic waves. This technology generates micro-vibrations that deeply cleanse both the interior and exterior surfaces enhancing the release of natural aromatic compounds and elevating the purity of the raw material.

Step 5

Rinsing

Following ultrasonic treatment, beans are thoroughly rinsed to completely remove residual impurities and particulates released during processing.

Step 6

Structure Stabilization

Coffee beans are brought to a stable state, sealing the cellular structure to lock in the flavor compounds that have been purified and optimized in previous steps.

Step 7

Roasting

Coffee beans are roasted according to precisely controlled temperature and time profiles ensuring optimal development of aroma, flavor, and the distinctive color characteristics of each product line.

Step 8

Degassing & Aroma Preservation

After roasting, coffee beans are rested under optimal conditions to allow CO₂ off-gassing, preserve full aroma, and balance flavor allowing the coffee to reach its most refined state before packaging.

Step 9

Final Sorting & Grading

Coffee beans undergo a final sorting process to remove defective, broken, or substandard beans ensuring absolute consistency in finished product quality.

Step 10

Packaging

Finished coffee is packaged in specialized valve-sealed bags preserving flavor integrity and product quality throughout storage and distribution.

Step 11

Quality Control & Distribution

Every batch undergoes rigorous quality inspection ensuring compliance with Pure — Honest — Authentic standards before reaching the hands of discerning coffee enthusiasts.

How Does Ultrasonic Technology Clean Coffee?

Ultrasonic technology uses high-frequency sound waves transmitted through water to generate millions of microscopic cavitation bubbles. As these bubbles form and collapse, they release powerful micro-level forces that effectively remove dust, impurities, mold spores, and chemical residues from every coffee bean reaching even the smallest crevices that traditional cleaning methods cannot

Why LOPHA Chose Ultrasonic Technology?

For LOPHA, adopting ultrasonic technology marks a defining step in our journey toward absolute purity. This breakthrough method delivers deep, chemical-free cleaning, safeguards the bean's original character, and reflects our long-term vision for sustainable coffee production.

Cleaning at the Microscopic Level

By emitting high-frequency vibration waves, ultrasonic technology penetrates the smallest crevices of every bean eliminating impurities, dust, mold, and bacteria that conventional cleaning cannot reach. The result: a fully cleansed coffee bean with its natural surface structure perfectly preserved.

Preserving the Pure, Original Taste

Unlike chemical or thermal treatments, ultrasonic waves clean without altering the bean's flavor allowing every variety to express its authentic, unaltered taste profile.

Trusted Across Multiple Industries

The safety and efficacy of ultrasonic technology have been validated across the food, industrial, medical, and electronics sectors a testament to its reliability and versatility.

A Greener Path Forward

Ultrasonic cleaning uses far less water than traditional methods, dramatically reducing wastewater output. Efficient, gentle, and environmentally responsible it embodies LOPHA's pledge to sustainable, future-focused coffee production.
