Manfred Hoffmann

from Wikipedia, the free encyclopedia

Manfred Hoffmann (* 1938 in Ringenhain near Friedland in the Czech Republic ) is a German agricultural scientist and was professor of agricultural process engineering ( agricultural engineering ) at the Weihenstephan-Triesdorf University of Applied Sciences .

Live and act

Hoffmann studied at the Agricultural Faculty Weihenstephan of the Technical University of Munich and completed his training with the second state examination after his legal clerkship. After teaching at an agricultural engineering school, in 1964 he was offered a position at the newly founded Weihenstephan-Triesdorf University of Applied Sciences in the field of agricultural engineering .

In his dissertation he dealt with questions of didactics in technical sciences . Shortly afterwards, he was appointed contact point manager for university didactics by the Bavarian State Ministry for Education and Culture and was particularly involved in the training of university lecturers, which was rewarded with the first award of a state prize for good teaching by the Ministry of Science. He was appointed as a lecturer at the Technical University of Munich, as part of the vocational school teacher training. He initiated a training program for organic farming at the Weihenstephan-Triesdorf University of Applied Sciences . His retirement took place in 1999. In the following years he campaigned for the spread of organic farming .

Hoffmann published around two hundred publications in various specialist journals and organized annual meeting days for the KV -Akademie and the KVSt Isaria zu Freising on questions of science and religion.

Scientific focus

In connection with work on chemical-free weed control, he developed the flaming technique which, in collaboration with Reinert, Weidenbach, led to today's leading technology in thermal weed control.

The search for detection methods for the influence of stress on food quality through technological influences in production led to the development of an electrochemical screening based on the redox potential , which today, in addition to chemical analysis, provides a more holistic statement on food quality with health-related significance (neutralization capacity for free radicals).

As an alternative to liquid fermentation, he developed a number of process variants for dry fermentation in biogas production. In contrast to the liquefaction of the biomass with a slurry-like digestate, a compost-like, low-odor final state is achieved. It is particularly advantageous that all methanisable biomaterials (organic waste, greenery accompanying roads and motorways, landscape maintenance waste, etc.) can be used with simple technology.
