What are the various types of bottle filling?

Bottle filling machines are in high demand in various industries, such as foods and beverages, pharmaceuticals, and cosmetics, to fulfill their business needs with minimal human intervention.

An automatic bottle filling machine or even a semiautomatic one can ensure proper liquid filling without any spill or overflow or such wastage.

Liquid Filling Types 

The liquid filling works under the principle of pouring the right amount of liquid into a container.

Since it is one of the most complex stages of the whole process, the liquid filling type will determine the suitable machine for various business needs. Different kinds of fillers available in the market are:

  • Gravity Filler: As the name suggests, gravity filling works under the theory of gravity because it uses the weight of the liquid to fill the container. It often works with a time-based feed, where the product gets supplied from a tank above.
  • Overflow Filler: The overflow filling method focuses on filling the bottles to the correct level. Excess product flows back into the storage container, preventing overflow. It gives a consistent look on all bottles. It is appealing to the customers to see all bottles uniquely filled.
  • Bottom-Up Pressure Filler: In bottom-up pressure filler machines, the nozzles get dropped through the bottle spout until it reaches the bottom. When the nozzle gets to the bottom, the liquid gets poured to the desired fill level. This liquid filling method is particularly beneficial for foaming liquids, such as carbonated liquids. 
  • Piston Filler: Piston fillers are one of the best mechanisms to fill thick liquids. The piston draws the product from the respective drum and injects it into the container. This particular system is very accurate and reliable. It can handle a wide range of fluids and could also get upgraded with additional filling heads.
