Vacuum + Heat
The WAVE Brew is a stainless-steel vacuum extraction kettle that connects directly to the chamber of any WAVE freeze dryer. Coffee grounds (in a filter bag) and water go into the vessel, then a vacuum is drawn — the water starts to boil at room temperature, gently extracting flavour without thermal damage. Up to 2 kW of heating keeps the liquid above its freezing point during evaporation, and the freeze dryer itself acts as the cold trap for the rising vapour. The result: a remarkably high-TDS extract (up to 20 %) with the full aromatic profile of cold-brew but in a fraction of the time. The same kettle works for tea, herbs, fruits, berries and any other liquid extract. The vessel is also pressure-tight, so once extraction is complete you can apply a slight overpressure to dispense the liquid cleanly. Freeze-dry the resulting concentrate and you have a premium instant powder — instant coffee, fruit powder, herbal extract — with a flavour profile no industrial spray-dryer can match.
WAVE WAVE Brew
The WAVE Brew is a unique machine featuring proprietary technology developed by WAVE. It can operate in three distinct modes:
Cold-brew coffee, in 30 min
Espresso-grade coffee grounds in a filter bag, water in the vessel. Pull vacuum, apply heat. The result is a 15–20 % TDS concentrate with smooth, low-acidity flavour — ready to freeze-dry into premium instant coffee.
Tea, herbal & botanical extracts
From green tea to chamomile to ginseng — the gentle vacuum extraction preserves volatile aromatics and active compounds that would degrade in conventional hot brewing.
Fruit & berry concentrates
Strawberry, blueberry, apple, grape, citrus — produce a clean concentrated juice with full natural colour and flavour, perfect for freeze-drying into instant powder.
R&D and small-batch production
Whether you're testing a new recipe or running pilot batches for a premium product line, the WAVE Brew gives you repeatable, lab-grade extractions in a compact footprint.
KEY FEATURES
Connects directly to any WAVE freeze dryer chamber
Vacuum boiling at room temperature — zero thermal damage
Up to 2 000 W heating to keep the liquid extracting, not freezing
Achieves TDS up to 20 % — far above any drip or cold-brew system
Pressure-tight vessel — use overpressure to dispense the extract
Universal: coffee, tea, herbs, berries, fruit, botanical extracts
VACUUM EXTRACTION
Pulling vacuum drops the boiling point of water below room temperature, so the extract bubbles gently without scorching the aromatics. Coffee, tea, herbs and fruit retain their original flavour profile.
INTEGRATED HEAT
Up to 2 kW of contact heating keeps the liquid above its freezing point during evaporative cooling — so the extraction continues smoothly instead of stopping at an ice block.
FREEZE-DRYER AS COLD TRAP
Connect WAVE Brew to the chamber of an FD260, FD440 or larger machine and the freeze dryer condenses the rising vapour, completing the closed-loop system.
PRESSURE + VACUUM
The vessel is rated for overpressure as well as vacuum, so once extraction finishes you can pressurise the kettle and dispense cleanly through the bottom outlet — ideal for filling vials, trays or bottles.
