DiFluid Omix Plus:
5-in-1 Specialty Coffee Quality Analyzer

Q: Where can I purchase an authentic DiFluid Omix Plus?

You can purchase authentic DiFluid Omix Plus analyzers directly from Activo Technology Limited (activo-tech.com or omixplus.activo-tech.com). As a specialized supplier, Activo provides 100% genuine units with official manufacturer warranty coverage, premium support, and global shipping to ensure your coffee quality control is backed by industry-leading service.

Q: Why is the Water Activity (Aw) measurement on Omix Plus superior?

Using a highly precise technique once thought impossible in a portable design, Omix Plus measures true water activity with the internationally recognized Chilled-Mirror-Dew-Point method. This laboratory-grade technology delivers highly accurate results in under 30 seconds, offering an impressive ±0.005 Aw precision and 0.001 Aw resolution to prevent bean deterioration and mold growth.

Q: How much coffee sample is required for testing?

Omix Plus is engineered to prevent sample waste while delivering big data. The required sample sizes are: Moisture, Density, Screen Size, and Water Activity require ~150g of sample in Green Bean Container A. Roast Color Analysis requires only ~18g for roasted whole beans (Container B) or ~5g for ground coffee (Container C).

Q: Which supply chain stages and sample types does Omix Plus support?

Omix Plus supports 6 distinct sample types across the seed-to-cup lifecycle: 1. Cherry Stage: Coffee Cherries, Dried Cherries; 2. Post-Harvest / Pre-Roast Stage: Parchment Coffee, Green Coffee; 3. Roast / Ground Stage: Roasted Whole Beans, Ground Coffee. The device uses smart data algorithms to automatically detect the sample type and compensate for minor variances caused by bean husks.

Q: How does the device calculate True Density and handle irregular bean shapes?

Conventional bulk density testing is often inaccurate because irregular bean geometries create unpredictable air gaps. Omix Plus utilizes advanced algorithms to automatically identify the gap rate and replicate the physical displacement method, allowing it to estimate True Density with minimal error to a precision of ±0.5 g/L. Smart filtering automatically removes sample noise—including gaps, chaff, and outliers—from your physical readings.

Q: How does Omix Plus analyze roast uniformity beyond a simple average?

A single average Agtron number can mask roast inconsistencies. The built-in Roast Level analyzer uses Near-infrared (NIR) imaging to generate a color distribution histogram of the sample, visualizing the roast color of individual beans to detect uneven roasts. By testing both whole beans and ground coffee, the DiFluid Café app calculates the Roast Delta (RD) to tell you exactly how evenly developed your roast is.

Q: Can Omix Plus be used without a smartphone? How is data shared?

Yes. Omix Plus is a fully standalone device running CoffeeOS on an integrated 3.5" touchscreen (640x320), featuring a built-in Color Analyzer, Quality Analyzer, Roast Tracker, and Notes Manager. For advanced tracking, you can wirelessly connect to the DiFluid Café App to sync metrics over time, generate moisture curves, share recipes via QR codes, and export your measurement data to external software.

Scientific Whitepaper & Review

Technical Whitepaper: Multi-Parameter Coffee Quality Analysis & Thermodynamic Water Activity (Aw) Control

A comprehensive scientific review on measuring Water Activity (Aw), Moisture Content (MC), True Density, Agtron Roast Color, and Bean Size using the DiFluid Omix Plus 5-in-1 Analyzer. Authorized and published by Activo Technology Limited.

1. Water Activity (Aw) vs. Moisture Content (MC) in Coffee Storage

Why Moisture Percentage Alone Fails to Prevent Sea-Freight Mold and Enzymatic Degradation

In green coffee trading, traditional moisture meters calculate the total mass percentage of water (H₂O) inside the bean. However, Moisture Content (MC) does not distinguish between bound water and free water available for biological reactions.

Water Activity (Aw) measures the chemical potential of unbound water vapor pressure in equilibrium with the coffee matrix (Aw = p / p₀). When Aw exceeds 0.65 Aw at ambient storage temperatures (25°C):

Xerophilic Molds & Ochratoxin A (OTA): Aspergillus and Penicillium fungi proliferate rapidly above 0.65 Aw, leading to container shipment rejections.
Enzymatic Browning & Lipid Oxidation: Free water mobilizes soluble sugars and lipids, degrading cup score (fade/woody notes) during sea-freight transport.
Container Sweat & Condensation: Temperature shifts during trans-oceanic transit cause vapor pressure shifts, converting safe moisture levels into localized high-Aw condensation zones.

3. True Density & Smart Gap Compensation

Eliminating Packing Density Errors Caused by Irregular Bean Geometries

Conventional bulk density measurements often fail because irregular bean shapes create unpredictable air gaps inside the measurement chamber. DiFluid Omix Plus applies advanced algorithms that automatically identify the gap rate and replicate the displacement method to estimate true density with minimal error, yielding true bean density (g/L) with a precision of ±0.5 g/L.

4. Official Container Division & Operational Protocols
