Title: Sechage solaire des aliments (solar food drying and conservation of food for year-round consumption) (in FR)

Abstract

This report is an introduction to food drying as a measure to avoid the loss of agricultural surpluses, and conserve food for year-round consumption. It discusses the basic rules of food drying and gives an overview of various methods and appropriate dryer constructions. It also provides detailed explanations on how to process vegetables, fruits, and meats and gives advice on storage and cooking.

  • A method of preparing large diameter solar cells has been developed to a stage where reproducible performances are obtained. While all the problems concerned with the intrinsic quality of the silicon used in the solar cells have not yet been solved, analytical methods have been developed for selecting the most suitable silicon samples prior to use. Studies concerned with the preparation of the substrate, deposition of the antireflection bed, and soldering of the connections are reported. Equipment for examining the solar cells is described.
  • The bibliography contains citations concerning the design and utilization of solar food driers. Solar collectors used are described in depth. Drying of fish, peanuts, fruits, potatoes, onions, garlic, ginseng, grains, coffee, and tobacco using this method is discussed. The use of focused solar energy and the addition of silica gel to drying foods are evaluated. Use of solar driers in the field, as a home preservation method, in underdeveloped countries, and as part of industrial food processing is considered. (Contains a minimum of 214 citations and includes a subject term index and title list.)

  • The results of a one-year study are presented on the optimization of silicon solar cells for operation under medium-range solar concentration (20 to 50). The problem of the solar concentration and the importance of the series resistance are considered as well as the necessity of an overall optimization which takes all parameters into account. The technological process of fabricating the optimized cells is described, together with a detailed analysis of the different contributions to series resistance. It is shown that the three main contributions are: the resistance along the lines of the grid of the front contact, the resistance ofmore » the base material, and the resistance in the diffused layer. The optimized solar cells, made as a result of this study present a lumped series resistance smaller than 20 m(ohms) for a 2 x 2 sq cm area, and the three main contributions are roughly the same. Such a cell exhibits a conversion efficiency of about 13.5% under AM1 (illuminated area, according to ERDA specifications). The possibility of again increasing the conversion efficiency through a further reduction of the series resistance is discussed.« less
