Virtual project engineering – including the integrated use of production drawings and 3D layouts as well as visualization – and the successful realization of individual vegetable, salad and fruit processing solutions you can take for granted.


Development of a system for vibration detection of the ripeness of fruit (VitERz.fruit)

Objective: Classification of fruit according to the degree of ripeness using a vibration analysis:

  • A prototype line is being developed with which the fruit is guided oriented and individually onto a flume, then the fruit is classified.
  • The vibration that the fruit applies to the flume is measured and evaluated using a self-learning system. 

Time to completion: May 2020-April 2022

Development of an innovative washing process for fresh-cut lettuce based on non-thermal plasma technology to increase product safety, quality and sustainability (SPLASH)

Objective: To examine the efficacy of the innovative disinfection technology using plasma-treated water (PTW) with regard to the disinfection efficiency in the washing water, resource conservation and the optimization of the transportability and shelf life of the products:

  • The procedure for the hygienic treatment of the salad is intended to reduce the risk of contaminated packaged salads with microorganisms.
  • A resource-saving washing process for cut salads is being developed, in which the product is gently hygienized using a non-thermal plasma process. 

Time to completion: November 2019-October 2022

Intelligently controlled thermal process in an apple washing line to reduce germ load at Fresh-cut products

Objective: Hygienize apples for Fresh-cut fruit salads to reduce food’s spoiling rate and to increase consumers’ safety:

  • Not just wash apples, but to also hygienize them in a gentle way and without using any additives or chemicals. It is planned to develop an innovative plant and process in order to do so. The system is supposed to be integrated into an existing processing line easily and flexibly.
  • By using temperature guided and controlled processes microbial pathogens which are spoiling food and pathogenic germs harming humans are reduced both by a maximum.
  • Due to the insulation of the new system it is optimized for the Fresh-cut industry, since it can be implemented in cold rooms without any disadvantages.

Innovative process to increase the microbial safety of packaged Fresh-cut salads by monitoring and hygienization of process water

Objective: Hygienize process water in a salad washing machine for ready-to-eat and Fresh-cut salads without using additives such as sodium chloride:

  • Increase consumers‘ safety due to a new method of hygienization based on a high redox potential
  • Taking the real conditions on-site into account, pathogenic germs harming plants and humans are minimized in the process water 
  • Reducing potable water consumption and thus decreasing costs, which is due to an optimum water use during the washing process by deploying cycle management.
