I am grateful for the opportunity to participate in this conference. I am probably the only one attending who comes directly from Old Europe. German and other European universities have not yet given sufficient consideration to food technology and technical equipment. This I can verify from my own experience, as at the present time I am one of a few teaching this subject at two universities.
More than 40 years ago I installed a cooking appliance in an airplane - maybe the very first one. This was a milestone and a few years later I turned completely toward engineering and commerce in this branch. About 4 years ago, by courtesy of the Whirlpool Corp., I obtained their layout of a spacecraft kitchen for a 3-man crew for a 3-week flight. This all seemed somewhat unrealistic at that time.
Professor Paul Buck had objections to the conservative cycle of meals the astronauts are required to maintain. I definitely agree. There is no relationship between space and the basic time periods of our daily life. Even when considering future commercial air transport we find similar conditions. Please imagine you are sitting in an SST plane above the middle of the Atlantic! What is Mr. Treadwell of Pan Am going to serve you: Breakfast or lunch ? Leaving Paris or London for New York at noon you expect lunch' But because of the local time difference you arrive at Kennedy Airport 3 hr earlier, just in time for breakfast. The question arises: From which coast will you determine the relative meal time ?
Some speakers have mentioned the microwave oven, and one pleaded for ovens equipped for defrosting, rewarming fresh grilled steaks from the deep-frozen condition, etc. May I add to these considerations a Werner Sell high-temperature oven which has been developed in my company and uses a method of fast-circulated hot air ? This oven is the result of extensive research and 15 years in service. Steady improvements have resulted in a tiny box with the following advantages
The electric power requirements are 3600 W for heating and 200 V for the motor.
In case there is any chance for a spaceship cabin to accommodate such equipment, we would be well prepared to develop a special small and lightweight oven with high efficiency. On my return to Germany I will carry with me a lot of problems and ideas, and I deeply hope that Europe will contribute its part in these great tasks.
