Biogas - a contribution to solving the energy supply problem of cheese factories. Biogas - ein Beitrag zur Loesung des Energieversorgungsproblems der gewerblichen Kaesereien

Abstract

During a 2-years-monitoring period different types of biogas-plants installed in the cheese factories 'Giessen', 'Steinenbrugg', 'Niederstetten' and 'Bodmen' have been investigated. Piggeries with 400 to 700 finishing places were attached to these cheese factories. These four milk processing plants are representative of an average Swiss cheese factory processing 800,000 to 1,500,000 liters of milk a year. The investigations showed that the energy-demand of the cheese-factories is ideal for the use of biogas. The capacities of gas- and hot-water-storage can be planned with a minimum reserve because in most cases cheese fabrication takes place daily. Apart from the fabrication process, the residence of the cheese maker, the cheese cellar, the feed-preparation, the finishing building and the hot-water supply need heat. There are no longtime peak-demands. The swine manure, well qualified for biogas production, is digested during a retention time of 2 to 10 weeks. The plants are heated with biogas excepted the one installed in 'Bodmen'. The gas yield of the mesophilic working flow-plants reaches 0.4 (Nm/sup 3//kgOS), which means the double value of the psychrophilic working storage plant 'Bodmen'. The plants in 'Giessen' and 'Steinenbrugg' need 20 to 40 (%) of the gas-production for their reactor-heating. Therefore the net gas-production  More>>

The plants in 'Giessen' and 'Steinenbrugg' need 20 to 40 (%) of the gas-production for their reactor-heating. Therefore the net gas-production of all four plants remained nearly identic. In all cheese-factories the biogas is burned for the heat-supply. The biogas covered of the total energy demand in the average 40 (%) in 'Steinenbrugg', 60 (%) in 'Niederstetten' and 33 (%) in 'Bodmen'. In 'Giessen' the rate was lower due to biogas-tests. An imaginary cheese-factory in the size of 'Giessen' equipped with a total energy-modul (gas-motor, generator, heat-pump) was tested by ENSIM. The result proofed that an energy autarcy is possible due to an enormeous technical installation.}
