Our Company

Evonta-Technology GmbH – Applied Technologies for Industry

We develop and automate diverse application technologies for various industrial sectors, modern agriculture and life sciences.

The main objective of our projects is to assist in the transfer of innovative testing and diagnostic procedures, as well as product processing technologies into industrial practice. As such, we are a full-service provider, which means that we supervise the entire development process from the initial idea to the final solution. Our services range from the analysis of customer-specific conceptual formulations and feasibility studies, to concept development and design, software programming, mechanical and electrical assembly, documentation and technical manuals creation.

Analysis of fertilized salmon eggs

Current State of the Art:

In commercial fish farming, such as the breeding of Atlantic salmon, fish roe is artificially fertilized in special containers. After 24-48 hours, a representative number of eggs is randomly selected, removed and treated with diluted acetic acid to assess the resulting fertilization rate per incubator. Through this treatment, the eggs lose their natural opacity, become transparent and can be examined under a light microscope. Until now, this inspection has been done manually, and is heavily dependent on the individual experience and knowledge of the operator. Additionally, the acetic acid treatment leads to a change in the internal structure of the eggs (denaturation), which can lead to interpretation errors in the microscopic evaluation.

Our solution:

A fully automated device for the non-destructive examination of fish eggs by means of Optical Coherence Tomography (OCT) allows capturing tomographic image data similar to Computer Tomography within a matter of seconds. The scanned fish eggs remain viable and can be examined in their natural state. To this end, the eggs are transferred into a water filled sample container, which is designed to let the eggs slide into fixed positions for measuring. The OCT probe above the sample container is positioned fully automatically above the egg to be tested. The camera integrated in the probe detects blastodiscs in the fish eggs and provides the coordinates for the subsequent OCT measurement. The data obtained are then evaluated and logged online. With the help of the determined fertilization rate, it is then possible to calculate the expected number of hatching eggs per incubator.

Hatching egg sanitation using accelerated electrons

Current State of the Art:

With the increasing specialization of the poultry industry and the continuous advancement of livestock management, we are witnessing an increase of environment-related infection hazard. Simultaneously increasing demands of quality and hygiene in poultry production, especially concerning hatching egg sanitation and the SPF (Specific Pathogen Free) area, create a need for new, effective, environmentally friendly and resource-saving treatment methods. Currently, the most widely used method for surface treatment of hatching eggs is fumigation with formaldehyde (HCHO). Due to the toxic and carcinogenic effects of formaldehyde, this method is controversial. Application bans are being discussed, but due to lack of alternatives, no ban has yet been implemented

Our solution:

The treatment of hatching eggs shells with low-energy accelerated electrons which hit the surface and penetrate into the porous calcareous eggshell. These electrons are generated by means of a special electron beam tube which enables a large-scale treatment of a various number of eggs in one shot. As a result, even invisible, hidden germs can be eradicated while the inside of the egg remains intact and the development of the chick can progress normally.
