Abstract: An in-shell egg pasteurization installation includes a temperature raising stage having a microwave cavity or microwave cavity portion into which microwaves can be radiated and a pasteurization stage having a microwave cavity or microwave cavity portion into which microwaves can be radiated. The installation is configured so as to provide radiant or conductive heat to an in-shell egg located in the temperature raising stage and to an in-shell egg located in the pasteurization stage, and to provide relative displacement between an in-shell egg and the microwave cavities or microwave cavity portions.

Abstract: An in-shell egg pasteurization installation includes a temperature raising stage comprising a microwave cavity or microwave cavity portion into which microwaves can be radiated and a pasteurization stage comprising a microwave cavity or microwave cavity portion into which microwaves can be radiated. Heating means provide radiant or conductive heat to an in-shell egg located in the temperature raising stage and to an in-shell egg located in the pasteurization stage, and displacement means provide relative displacement between an in-shell egg and the microwave cavities or microwave cavity portions.

Abstract: An in-shell egg pasteurization process (10) includes, in a temperature raising stage (16), raising the temperature of albumen of an in-shell egg predominantly by means of microwave radiation to a temperature between 57° C. and 60° C., the albumen temperature being raised at a rate which reduces at least once over time. Simultaneously, in the temperature raising stage (16), the temperature of an external surface of the egg is raised predominantly by means of external heat radiation or conduction to a temperature of between 57° C. and 70° C., or alternatively or in addition the egg surface temperature is allowed to rise to a temperature of between 57° C. and 70° C. as a result of the microwave radiation by inhibiting heat loss from the egg. Said temperatures are then maintained by means of microwave radiation and external heat radiation or conduction for at least some time.

Abstract: A process for obtaining a valuable product from plant material comprising both proteinaceous material and fibrous material includes brushing or scrubbing the plant material in a wet condition in a separation stage against a separation medium, thereby forcing proteinaceous material through the separation medium and retaining fibrous material on the separation medium, and withdrawing a fibre-rich product and a protein-rich product from the separation stage.
