The challenge
Primary use cases: instant/soluble coffee production; premium-blend extraction; waste valorization (grounds, chaff, milling effluent); wastewater closure in wet-processing facilities.
Industries and users: coffee roasters, instant-coffee manufacturers, specialty coffee processors, sustainability-focused producers.
Scale: modular units 50–500 t/day per unit; stackable for facility integration.
ARBOK solution
ARBOK-COFFEE applies ARBOK-VC (vacuum cracking) to coffee production across three domains: (1) low-temperature extraction and component separation preserving volatile aromatics; (2) vacuum-assisted drying of coffee extracts (replacing spray-dried and freeze-dried methods); (3) closed-loop processing of coffee waste (grounds, chaff, pulp) and wastewater. Recovers clean water, coffee oils, and fermentation substrates; reduces energy 15–25× (50–100 kWh/t → 1–2 kWh/t); improves taste profiles of commodity-grade coffee to premium-equivalent quality, enabling 20–30 % price uplift.
Coffee extract enters a vacuum chamber where water evaporates at ambient temperature; volatile aroma compounds (esters, aldehydes, oils) remain in vapor phase and are recovered separately from non-volatile solids. Unlike spray-dried (100+ °C, aroma loss) and freeze-dried (ice-crystal damage), ARBOK operates at ambient temperature under deep vacuum, preserving taste complexity. For waste streams: grounds and pulp are separated into water (potable-grade), coffee oils (reusable for flavoring), and dry solids (for biogas/biofuel).
Market and application
Global instant-coffee market ~5 million tons/yr, ~$10 billion. Spray-dried dominates (cost-driven); freeze-dried premium niche. ARBOK enables commodity-to-premium migration without freeze-dry cost, capturing ≥ 10–15 % of spray-dried volume over 5–7 years. Early adoption in Vietnam, India, Colombia (high-volume commodity regions); sustainability-driven markets (EU, North America).
Per 200 t/day unit: energy savings ~$50 000/yr; price uplift (20–30 % premium) ~$3–4.5 million/yr; co-products (oils, waste byproducts) ~$5–10 million/yr. Total annual benefit $8–15 million; CAPEX payback 3–5 years. Modular scaling: 50 t/day units for smaller producers (~$1–2 million/yr benefit).
Use cases
Primary use cases: instant/soluble coffee production; premium-blend extraction; waste valorization (grounds, chaff, milling effluent); wastewater closure in wet-processing facilities.
Industries and users: coffee roasters, instant-coffee manufacturers, specialty coffee processors, sustainability-focused producers.
Scale: modular units 50–500 t/day per unit; stackable for facility integration.
Steps: coffee characterization (grade, moisture, oil content) → unit sizing → install (4–12 weeks) → process optimization → production ramp. Continuous or batch mode, automated, minimal labor (1–2 technicians per shift).
Retrofits to existing instant-coffee lines with minimal process interruption; integrates with roasting, milling, fermentation workflows; can feed co-products (oils, composts) to adjacent agri-feedstock or biogas units.

For waste streams: grounds and pulp are separated into water (potable-grade), coffee oils (reusable for flavoring), and dry solids (for biogas/biofuel).
Extraction: water recovery 100 %; aroma compound recovery ≥ 95 %; no reagents, no membranes.
Drying energy: 1–2 kWh/t (vs. 50–100 kWh/t for spray/freeze-dry); cycle time ≤ 8 h for batch.
Waste processing: water extraction 99.98%; oil yield 3–5% (w/w dry grounds); solids dry to 10–15% moisture.
Output quality: instant coffee granule morphology uniform; taste scores premium-equivalent; no oxidation.
Vacuum extraction chamber; aroma-vapor recovery condenser; solids dryer; oil separation centrifuge; wastewater-processing module; PLC/automation + process analytics. Modular, containerized (20–40 ft); operates on standard power supply.
Technical: ambient-temperature processing (no thermal damage); aroma preservation (15–25× vs. traditional); composition-independent (handles all coffee grades).
Economic: energy savings €4.9–9.8 per ton; price uplift on commodity coffee +€600–900 per ton (20–30 % margin gain); co-products (oils, waste valorization) €5–10 million/yr for mid-size producer; payback 3–5 years.
Environmental: zero discharge (water loop closed); no chemical additives; CO₂ footprint 80–90 % lower than spray/freeze-dry; suitable for water-stressed regions (reuse up to 95 %).
Strategic: enables "specialty from commodity"; circular supply chain; eligible for ESG/carbon credits; supports sustainable sourcing narratives.
