Fuente: WIPO "industrial hemp" An apparatus for steam treating plant fibres and a method of steaming plant fibres. The apparatus comprising a container for a batch of plant fibres, a steam manifold that is adapted to receive steam from a steam source and to deliver steam to the interior of the container. The apparatus further comprising an ambient temperature sensor for sensing an ambient temperature outside the container, and a controller configured to receive a signal from the ambient temperature sensor and to control steam delivery from the steam source to the container. The controller is configured to control the period of time of steam delivery based on the signal from the ambient temperature sensor. The method of steaming plant fibres The method comprises the steps of delivering steam from a steam source, through a manifold, and into a container containing the batch of plant fibres; sensing an ambient temperature; and controlling the period of time of steam delivery to the plant fibres in response to the sensed ambient temperature.
