Abstract
A separable coupling for filling or emptying a bulk container of a liquid or semi-liquid food product comprises a closure on the container, and a coupling member attached to a supply or discharge conduit and which is releasably connectable with the closure. Valves on the closure and coupling member are connected in series in the product flow path when the coupling is made. They are connected mechanically together and actuated in series so that the valve of the coupling member is actuated through the agency of the valve on the closure in a fail-safe manner. Provision is made for feeding superheated steam to the part of the product flow path lying between the valves, so that the exposed surfaces of the closure and coupling member can be sterilized or purged before and after a filling or discharging operation.
