Pressure filling machines are the most popular of all filling machines we sell. An inline pressure filler like the one below is economical, robust, and fills to a liquid level height evenly for all of the bottles which is a very important factor for consumer satisfaction. A pressure filler can be configured for automatic or semi-automatic operation with from 2 – 24 heads (depending on bottle size) and from one ounce to 10 Ltr.
In pressure overflow filling systems the product is pumped or gravity fed from a tank through a filling valve to the container. The filling valve contains an over flow tube to drain the excess product back to the supply tank and prevent overfill. The fill level of the container is determined by the depth of the overflow port within the neck of the container. When the product reaches the overflow port, the fill is completed, but the flow continues through the overflow tube until the seal on the container is broken and the valve sleeve covers the ports in the filling nozzle and stops the flow. The fill level will be the same regardless of bottle inconsistencies. |
