CEPT® vs PEF

The patented CEPT®  technology is based on PEF (Pulsed Electric Field) but differs in many ways. Learn more about the uniqueness of CEPT® and its advantages. 

The power of CEPT®

CEPT® stands for Controlled Environment Pulsed Electric Field Treatment.

It is a refined or further developed version of Pulsed Electric Field (PEF) The system allows for optimized control and application of electrical pulses in various biological processes.

 

PEF technology in general, and CEPT® in particular,  provides advantages across several food products (liquids, solids, semi-solids). The patented CEPT® treatment can be applied to a wide range of food products.

For example, in olive oil, wine, and juice as well as the extended shelf life for cold-pressed fresh juices.

Furthermore, in solid food products, the OptiCEPT system improves efficiency and quality in potato processing and drying of fruits and vegetables.

The CEPT® platform is a high-voltage generator combined with treatment chambers. The technology is primarily used within food production to increase extraction and extend sustainability. OptiCept uses short-term high voltage pulses (PEF) to shatter the cell membrane which increases the extractability of the substrate and destroys unwanted microorganisms.

CEPT® advantages

Compared to traditional PEF, CEPT® has several advantages. 

It is an easier way to create, control, and apply pulses more efficiently (Switched power and component development).

Through different settings, CEPT® can easily change e-field, pulse width, frequency (PPV), and strength after the requested treatment.  

CEPT® machines can be run bipolar and monopolar. (Cleaning and wear of the electrodes can be handled more easily.)

The flow can automatically be adjusted, which means that it always achieves an effective treatment and always needs the same energy (KJ/kg) for the substrate, independent of the conductivity.

The CEPT® treatment chamber(s) are designed to optimize the treatment effect, with a unique design in terms of shape, flow, and materials.

Square pulsed - the ultimate shape

To achieve the optimal treatment with PEF, you need to create the electrical pulses as close to a square as possible.

 

Some PEF systems have less sharp pulses due to various reasons, for example, a long rise and fall time of the pulse. Some old generators used “spark gap” technology which discharges the capacitors completely. Some generators have small capacitors, so the pulses drop a lot during the pulse.

 

Nevertheless, it is impossible to create a perfect square pulse due to physical limitations.

 

However, the CEPT® platform has a “minimal inductance design” which creates the sharpest possible pulse.

 

The pulse efficiency enabled by the CEPT® system can be explained by the sharp pulses and  “automated recipes”. Given that, the user doesn’t have to select certain recipes since the generator automatically sets the optimal settings.

 

Furthermore, CEPT® has a unique efficiency and can treat at half the generator power compared to traditional PEF. 

 

The CEPT® system manages any objects that accidentally could end up going through the chamber due to short-circuit and over-voltage protection.

 

Lastly, the installation is very simple, some PEF systems require transformer oil, meaning that the installation requires a separate fire-protected room.

 

That is to say, the OptiCEPT PEF system has a much smaller footprint, both in terms of physical space and in terms of energy efficiency.

Maintenance is also convenient, with an Easy-to-clean chamber with a raisable dual conveyor belt in the systems for solid foods.
