VENTING VALVE FOR FILLING SACKS WITH FLUIDISED PULVERULENT PRODUCTS |
摘要 |
<p>A deaerating valve for bagging fluidized pulverulent products into sacks of the open-mouth type. The valve includes a filtering sheet housed on the inside of the sack to be filled, this sheet having a texture and a thickness such that it multiplies the suction effect through the valve and plays the role of a "wick" to drain the air into a large space. The dimensions of the sheet are considerable with respect to those of the deaerating valve; its surface area may attain that of the flat spread-out sack. The invention is useful in the removal of air from impermeable bags designed to receive a micromized pulverulent product.</p> |
