Introduction– Liquid bottle filling machines are equipment used in various industries where liquids are to be filled and packed in various types of containers. They come in manual, semi-automatic, and fully automatic versions and are designed to be compact, versatile, and to increase productivity while delivering quality and consistency. Volumetric fillers are more accurate and specialized as they require specialized instruments for calibration, balance, and timing. They fill containers with a consistent volume of the product through a time-based filling principle and ensure the container is filled with the same amount of product. Manufacturers provide a range of quality standard filling machines to suit a wide variety of liquids, bottle sizes, and production output. Many of them are scalable as additional filling heads can be added at any time.
Reasons to Use a Volumetric Liquid Bottle Filling Machine
Bottle fillers can produce a large number of filled products in lesser time than would be conventionally required using manual labour. Using an automated bottle filler can remove any kind of uncertainty from the filling process. Another advantage is that once production demand reaches a certain higher stage it becomes tedious to complete each fill using manual labour. Versatility is another element where it concerns using multiple bottles for a single product. The liquid bottle filling machine can drastically reduce the change over time between two bottle types or where the fluid viscosity differs. The modern technology also comes equipped with PLC controls and an easy user interface and with a growth potential to expand the production as business upscales.
Difference Between Liquid Filling Machines and Volumetric Filling Machines
Volumetric filling machines fill bottles with a precise volume of liquid. Alternatively, liquid level filling machines are made to fill containers up to a specified level on the container even if the exact volume on each bottle is not the same. Volumetric machines are also inherently less costly and are easy to tune and use.
Types of Volumetric Liquid filling machines
- Gravity Fed Fillers- This is a cost-effective and an excellent option for volumetric filling and is designed for low viscosity and foamy liquids.
- Piston Fillers- Piston Fillers use a highly accurate volumetric filling technique and ideal for thick or highly viscous liquids. The Piston Fillers are of two types-check valve piston fillers and rotary valve piston fillers.
- Pump Fillers-They is very versatile and suitable for a wide range of liquids and viscosities.
- In-line Filling Machines- These are suitable for filling containers in a line and most suitable for operations where different container sizes are involved
- Rotary Filling Machines- They are meant for faster speeds and higher production rates and more specialized and customized in nature.
Amongst the above types, there are high-end variants like the Automatic four head volumetric machines, the two head piston machines, the oil filling machines, and machines exclusively designed for adhesive, cream, and jelly filling.
Factors to be considered while choosing the liquid bottle filling machine
Choosing the best liquid bottle filling machine is a decision where many factors are required. Product attributes and container characteristics to fill size as well as the production rates need to be considered. There are factors like regulatory issues, safety requirements, and expansion plans which also determine the installation of the type of liquid bottle filling machine. Large and reputed suppliers of packing and filling equipment work closely with clients to identify the most cost-effective and practical solution. They identify need-based machinery and customize it with versatility, flexibility, reliability, accuracy, and affordability.
