Oil Extraction from Algae


One of the main issues is efficient extraction of the oil from the Algae. While this can be done by drying then pressing the algae powder, an in process soluable method is easier. Hielscher has a device for about 13K that uses ultrasound technology to breakdown the cellular walls and extract the oil. This model uses about 1000watts.

The UIP1000hd (20kHz, 1000W) is a powerful and adaptable ultrasonic device for lab testing and industrial processing of liquids. It is used for applications, such as emulsifying, dispersing & particle fine milling, lysis & extraction or homogenizing.
The UIP1000hd is the powerful link between laboratory testing and the industrial processing of liquids. It combines the flexibility and easy handling required in the research and development with an outstanding performance in heavy-duty operation. For this reason, this single device is used for lab scale feasibility testing, process optimization, and process demonstration for ultrasonic liquid processes.
Adaptable System to Fulfill R&D Needs

Since the UIP1000hd is very flexible and adaptable, it is being used in many R&D facilities and universities, today. The flexibility of the UIP1000hd results from an extensive list of manifold accessories, such as sonotrodes, boosters and flow cells. In combination with a sonotrode and the stand, you can sonicate sample beakers (click to enlarge picture) to test various liquid formulations for their response to sonication.
For the processing of batches larger than 5 liters, we generally recommend to sonicate using a flow cell reactor (flow mode) in order to obtain a better processing quality. When used with a flow cell (right picture) you can run larger samples in recirculation to establish the correlation between parameters, such as amplitude, pressure and liquid composition, and the process results and efficiency. When used for the sonication of liquids in flow mode, the UIP1000hd can typically process between 0.5 and 4.0L/min (The actual rate will depend on your process). As the UIP1000hd is full industrial grade, it can be operated 24 hours per day (24h/7d). A UIP1000hd can typically process approx. 1 to 5m³ per day. For higher production throughput, we recommend using either multiple units or one the larger ultrasonic devices:
