Operation steps

Step 1: Heating and stirring

Prior to filling, such products as butter or spread should be heated to lower their viscosity. Heating and stirring system continuously heats and stirs the product to maintain a uniform consistency and temperature.

Step 2: Containers destacking

The empty containers are destacked by a vacuum cup system from the empty containers magazine and indexed by the starwheel towards the filling station.

Step 3: Filling of the product

The preheated paste product is filled into the containers through the custom nozzle having multiple holes to ensure uniform filling of the paste product. The materials used for filling product are food-grade plastics and stainless steel. After the required amount of product came out, the nozzle is closed with the special rotary shut-off means.

Step 4: The lids destacking

The lids are automatically destacked and dispenced from the lid magazine by a vacuum cup system and transferred to be placed under the container to be closed.

Step 5: Lids placing and pressing

The filled containers are indexed by the starwheel towards the lid closing station where the lid is applied onto the container and pressed to it.

Step 6: Containers discharge

The filled containers are indexed by the star wheel towards the outfeed conveyor and elevated to the upper level of the starwheel and then pushed out onto the outfeed conveyor.

Step 7: Containers further processing

After filling and lid closing, the containers are transferred by outfeed conveyor for further processing steps: applying of sleeve or labeling, and printing of product data on it.
