Abstract
An air lock transfer device allows the transfer of substances between environments at different pressures, without disrupting the integrity of the pressure differential therebetween and which allows for a near continuous product flow between environments. The device comprises a housing and a transfer mechanism reciprocating within the housing such that at least two product chambers within the transfer mechanism simultaneously communicate with an outlet port and one of at least two inlet ports contained in the housing to allow product to be simultaneously loaded and discharged from the housing.
