Glycol Chiller for cold brew coffee

The core function of the water cooler in the cold extraction coffee system is to provide and maintain a constant temperature of 0–5℃ for the cold water environment, ensuring the stability and flavor consistency of the long-term low-temperature extraction process, and avoiding the occurrence of astringency or turbidity due to temperature fluctuations.

Core functions and application scenarios

‌Precise temperature control‌: Maintain the water temperature at approximately 4℃ (traditional cold extraction requires <5℃), inhibit the excessive release of stimulating substances such as chlorogenic acid, and retain the floral and fruity aroma and sweetness.

‌Continuous/batch production‌: Replace the refrigerator soaking method in commercial systems, support 24-hour uninterrupted operation, suitable for coffee shops, ready-to-drink beverage lines, and central kitchens.

‌Process compatibility‌: Achieve dynamic extraction in conjunction with the circulating pump, shorten some process times and improve extraction uniformity; also provide a cold source foundation for "instant cold extraction" equipment.

‌Hygiene guarantee‌: The sealed circulation reduces the risk of oxidation and microbial growth.‌‌‌‌

The water chiller provides active cooling and maintains a constant temperature, eliminating the interference of ambient temperature. It is suitable for high-frequency or large-scale production.
