This study traces how the environmental effects of industrialization reverberated through the cinema of Germany’s Weimar Republic. In the early twentieth century, hygiene encompassed the myriad attempts to create healthy spaces for life and work amid the pollution, disease, accidents, and noise of industrial modernity. Examining classic films—including The Last Laugh, Faust, and Kuhle Wampe—as well as documentaries, cinema architecture, and studio practices, Paul Dobryden demonstrates how cinema envisioned and interrogated hygienic concerns about environmental disorder. Framing hygiene within the project of national reconstruction after World War I, The Hygienic Apparatus explores cinema’s material contexts alongside its representations of housework, urban space, traffic, pollution, disability, aging, and labor. Reformers worried about the health risks associated with moviegoing but later used film to popularize hygienic ideas, encouraging viewers to see the world and themselves in relation to public health objectives. Modernist architecture and design fashioned theaters into regenerative environments for fatigued spectators. Filmmakers like F. W. Murnau and Slatan Dudow, meanwhile, explored the aesthetic and political possibilities of dirt, contagion, intoxication, and disorder. Dobryden recovers a set of ecological and biopolitical concerns to show how the problem of environmental disorder fundamentally shaped cinema’s relationship to modernity. As accessible as it is persuasive, the book adds to a growing body of scholarship on biopolitics within German studies and reveals fresh ways of understanding the apparatus of Weimar cinema.

This text covers the design of food processing equipment based on key unit operations, such as heating, cooling, and drying. In addition, mechanical processing operations such as separations, transport, storage, and packaging of food materials, as well as an introduction to food processes and food processing plants are discussed. Handbook of Food Processing Equipment is an essential reference for food engineers and food technologists working in the food process industries, as well as for designers of process plants. The book also serves as a basic reference for food process engineering students.The chapters cover engineering and economic issues for all important steps in food processing. This research is based on the physical properties of food, the analytical expressions of transport phenomena, and the description of typical equipment used in food processing. Illustrations that explain the structure and operation of industrial food processing equipment are presented. style="font-size: 13.3333330154419px;">The materials of construction and fabrication of food processing equipment are covered here, as well as the selection of the appropriate equipment for various food processing operations. Mechanical processing equipment such as size reduction, size enlargement, homogenization, and mixing are discussed. Mechanical separations equipment such as filters, centrifuges, presses, and solids/air systems, plus equipment for industrial food processing such as heat transfer, evaporation, dehydration, refrigeration, freezing, thermal processing, and dehydration, are presented. Equipment for novel food processes such as high pressure processing, are discussed. The appendices include conversion of units, selected thermophysical properties, plant utilities, and an extensive list of manufacturers and suppliers of food equipment.
