Lab PEF Unit

Lab PEF Unit

DTI builds a range of Pulsed Electric Field (PEF) systems for R&D, small-scale, and large industrial applications. DTI’s Lab PEF Units are ideal for research, determining optimized PEF parameters for application scale-up, and for low volume production. DTI’s Lab systems come with an easy-to-use touchscreen interface, and a single treatment chamber where high voltage pulses are applied to the product. 

DTI configures treatment chambers for both static and continuous applications. A continuous treatment chamber (shown in the left upper image) allows pump-able product to flow through the system assuring that all product receives the desired PEF treatment. A static chamber (shown in the left lower image) is ideal for processing solids (e.g. plant tissue) in a water bath.

DTI has installed PEF Units at universities and research centers around the world for food and biomass research. Many of these research centers are available to assist industry in assessing potential applications. DTI also offers rental units that can be shipped to the customer's facility for initial trials.

The front-mounted touch screen PLC provides simple operations and precise control, while the static or continuous treatment chamber enclosure located on the side allows for ease of cleaning and assembly. The pulsed electric field is applied to the fluid as it flows through the treatment zone.
