The Ray is the entry level into automatic feeding. It's compact design and simple operation make it ideal for replicating continuous AD processes at the lab scale, especially for long term monitoring, stability assessment or AD modelling.
With two large 10L reactors, its volume produces large quantities or gas, constructing clear biogas production dynamics and making it easy to spot deviations. Learn how best to operate your AD plant by running a Ray in parallel, and experimenting in a risk-free lab scale environment.
After the initial setup, simply top up your feeding syringe when it runs out (~ weekly), and empty your effluent bottles to prevent pressure building in your reactor (~2x/week).
Each reactor has its own feeding rate, so you can model two setups with the same machine. Compare the results from different OLR's or test other variables such as feedstock/additives.
2x 10L Reactors
you have the freedom to test different feedstocks, conditions, or additives. 1L reactors are well suited to low total solid feedstocks (<12%)
2 Automatic Feeders
experiment with different feeding rates, to model your response to changes in gas production
The robust stainless steel reactors provide the non-reactive environment for anaerobic digestion. Enquire for different reactor volumes.
The easily removable effluent bottle collects the excess digestate to avoid pressure build ups and spillages.

Automatic Feeder Syringe
The patented feeder syringe feeds the reactor at your programmed rate. It prevents backflow from the reactor and a full syringe feeds for about a week.
Mixer motor
Each reactor comes with a 20 rpm motor which constantly mixes the inside of the reactors.
Heater Jacket
The custom fit heater jackets maintain a consistent, programmable temperature inside the reactor.
Agitator Motor
To ensure homogenous feed, the agitator mixes the feedstock coming up from the feeding syringe.
Our open source Arduino data logger records and stores the gas production data measured by the gas flow meter. When an event happens in the gas flow meter, a reed switch circuit is closed which is logged by the data logger. The BMP280 pressure sensor and thermocouple inform the data logger to automatically convert any gas volumes to STP. Data is easily extracted at any time through USB connection with any computer.
