DALUM Equipment offers proven and patented equipment for commercial kombucha producers. At DALUM we offer small scale systems with a capacity ranging from 1 kg/hr CO2 to over 50kg an hour.
In 2024 JuneShine became the first hard kombucha brewery to implement small-scale CO2 recovery technology, when they installed a DALUM CO2 Recovery Plant. By producing their own beverage-grade CO2 with over 99.9% purity, JuneShine cuts cost from purchasing CO2, strenghtened supply chain resillience, and reinforced their commitment to brewing sustainable kombucha.
“This CO2 recovery technology from DALUM allows us to capture and reuse CO2 directly from our own fermentation, ensuring it’s pure, natural, and fully aligned with our values of creating a better for you, better for the planet product.”
-Luke Suttmiller, JuneShine’s Sustainability Manager and Head Brewer
During the fermentation process, kombucha producers naturally release large volumes of CO2 as a byproduct. Kombucha producers later purchases CO2 for use in carbonation, packaging and pressurization. This industrial CO2 is often purchased at an increasing price and with an unpredictable supply.
Recovering CO2 on-site offers a smarter, more sustainable alternative. By capturing, purifying and liquefying the CO2 emitted during fermentation, kombucha producers can use their own recovered CO2 in the production processes. This not only reduces reliance on external suppliers and but also enhances operational efficiency and supports sustainability goals.
The CO2 liquefaction process typically involves four major steps:
Compression: Raw CO2 gas is compressed to increase its pressure, preparing it for cooling and purification.
Cooling: The gas is cooled to near its condensation point, often using refrigeration systems.
Purification and Dehydration: Moisture and impurities such as alcohols or hydrocarbons are removed to meet food-grade or industrial standards.
Liquefaction: At high pressure and low temperature, CO2 is transformed into a liquid, which can then be stored or transported.
DALUM Equipment’s systems are designed to perform these steps with high energy efficiency, minimizing thermal losses and maximizing CO2 recovery yield. The result is a clean, liquefied product ready for reuse or sale.
