    摘要： A method and apparatus for filling containers, such as valve bags, with particulate material that is considered difficult to package. An inlet valve provides access to the top of a vertically disposed hopper containing a lower porous pad through which fluidizing air is injected. A horizontal filling spout extends through the sidewall near the hopper bottom, and additional air is injected into the spout and also into the upper portion of the hopper. A vibrator associated with the hopper at a location above the longitudinal center thereof applies lineal vibration to the hopper, preferably along a line at an angle to the horizontal between 35* and 55*.
