A sterilization apparatus includes a housing adapted for receiving a removable rack with open shelves supporting containers with the substance to be sterilized, a fan arranged at the top of the housing, and a cooling device for subsequent cooling of the sterilizing fluid introduced into the housing. To increase the uniformity of whirling of the fluid around the containers on different levels of the rack and thus to increase the heat transfer to, and the subsequent heat removal from the containers, a timing-and flow-controlling device is provided for cyclically changing the flow of the sterilizing fluid through the rack during the heating-up and cooling-down of the sterilization cycle, either by alternating the direction of the flow, or by distributing periodically partial streams through different shelves of the rack. |
