- Feed Hopper
Feeding hopper or containers are the regions where the milk is filled that is to be packaged. These containers sometimes carry raw milk that is flavored, pasteurized or mixed is further containers and us prepared as final packaging product. There is also a small hopper ahead of small milk filling machines which are used for low production setups.
- Sensors
Sensors are the main security concerns that are built-in in a milk filling machine. These sensors are used for identification of bottles or containers that whether they are placed exactly under filling head or not. After confirming the presence by these sensors, the system allows the filling head to release milk product present in the hopper or feeding area.
- Filling Head
Filling heads are the one from where the milk product is released into the bottles or conveyors. These filling heads are made up of stainless steel that never allows as contamination or rusting. Filling heads are also easy to remove and clean and are available in different opening sizes depending upon the packaging product.
