<p>The body (1) has a fluidizer arranged in flow direction of a material downstream of a fluidizer bulking or pinch valve (20). A discharge pipe is ventilated by a ventilating device (50) and arranged in the flow direction of the material downstream of the pinch valve. A retention device holds containers (60). A gas inlet pipe (12) is connectable with a gas supply such that gas with high pressure is blown into interior of a fluidizing hopper (11) through the pipe from the gas supply, and solid particles in the existing gas are fluidized when the body is operated. An independent claim is also included for a method for metering a fluidizing solid material.</p>
