Different Types Of Liquid Filling Machine You Should Know

1.What Do You Know About Different Types Of Liquids?

Liquids flowing on a hand

Liquid can be defined as a state of matter with a specific volume but no fixed shape. It can be distinguished from all other matters on its characteristic to flow. Liquids can be categorized as free flowing, non free flowing, viscous, and thick liquids due to their resistance to flow. Similarly, liquids are considered flexible substances due to their ability to adapt any shape in when they are placed.

As liquids are of different types, their handling and packaging is carried out by keeping their distinct specifications. In this way, one of the most critical tasks is the accurate filling of different types of liquids for which the packaging equipment manufacturers have pioneered range of liquid filling machines which you will be knowing in the upcoming questions.

Some of the common liquids include:

• Water
• Beverages
• Sauces
• Lubricants
• Chemicals
• Cream
• Shampoo
• Syrups

2.Different Types Of Liquid Filling Machine- Filling Measurement Method?

Depending upon the nature of liquids, different types of liquid filling machines are designed to better deal with their filling. Similarly, the most important categorization made is the different types of liquid filling machines according to their measurement method. It simply explains the multiple methods being employed for filling liquids precisely. These are as follows:

Liquid Level Filling Machine

Liquid level filling machine is also known as overflow filling machine. It is the popular type of machine which fill liquids into containers to a fixed level. Mostly, it uses a diving nozzle which dive into container and dispense the liquid into it. The nozzle retract when predetermined level is achieved and in case of over filling, excess liquid is sent back to reservoir.

Benefits

• It helps in reducing material waste by employing overfilling technique.
• The possible creation of foam during filling is eliminated with the use of diving nozzles.
• The machine is suitable for all types of containers by employing level based filling.

Limitations

• Processing highly valuable liquids by liquid level filling machine may cause economic losses due to the variations in product volume.
• It is undesirable for liquids which needs strict administration of filling exact dosage.

Application

Liquid level filling or overflow filling machine is best suitable for liquids of medium to low level viscosity such as edible oil, pesticides, bleach, and liquid detergent etc.

Volumetric Liquid Filling Machine

Volumetric liquid filling machine is another type of liquid filling machine that fills containers with a predetermined quantity of liquid, measured by the volume displaced rather than checking the net weight or level of the filled container. It is best suitable for precise volume filling, however, due to the variations of liquids, volumetric liquid filling machine can be further divided into three types:

Piston Filling Machine

Piston filling machine is one of the popular types of volumetric filling machine which measure and dispense liquids by using a piston cylinder. The desired volume of liquid is drawn into a cylinder which is then pushed to discharge the liquid into container via nozzle. The volume of liquid can be simply increased or decreased by modifying the length of piston's stroke.

Piston filling machine uses two types of filling mechanism naming check valve piston filling and rotary valve piston filling. The former is suitable for liquids without any particles, while as, the later support thick liquids with small to large particulates.

Benefits

• Maintain high filling accuracy.
• It is safe for all kinds of food grade liquids.
• Precise structure with small footprint and easy handling.

Limitations

It can only accommodate limited volume of liquid at one type.

Application

Piston filling machine is best applicable for thick and viscous liquids which can be flat or with particulates. The common examples include ketchup, mayonnaise, pickles, sauces, jam, and cream etc.

Gravity Filling Machine

As the name indicates, gravity filling machine works on the principal of gravitational force. It has a large reservoir or tank placed on the top of machine which has a connection with filling heads. Similarly, the containers are filled when valves of the nozzles are removed from nozzles and liquid start flowing downward into awaiting bottles. Fill volume is determined by the timers which regulate the closing and opening of valves, therefore, it is also called time-based filling machine.

Benefits

• Good for delivering exact volume.
• It can work pretty well for filling liquids with identical characteristics.
• It is cost-effective by using simple filling method of gravity, thereby, ending need for special measuring systems.

Limitations

• Unsuitable for thick and viscous liquids.
• It requires complete rebalancing if user want to process different liquids which is both time taking and expensive.

Application

Gravity filling machine is a good choice for the filling of free flowing liquids and liquids with low level of viscosity that do not change with ambient temperature such as chemicals, milk, coffee, beverages, and paint etc.

iii. Pump Filling Machine

Pump filling machine is yet another type of volumetric liquid filling machine. It employs pump mechanism for the measuring and dispensing of liquids. The machine is independent in its performance by taking liquid from hopper, weighing it properly, and transferring it into the underlying containers through single or multiple filling heads.

The pump mechanism include peristaltic pump, gear pump, and rotary pump. Each type is used for enhancing the filling efficiency and fill volume accuracy.

Benefits

• High filling accuracy.
• Pump filling machine is a versatile equipment that does not require parts changeover for eclectic filling requirements.
• It can deal with small to large fill volume.
• Wide range of models to suit various industries.

Limitations

For filling foamy liquids, the speed of pump filler is supposed to be reduced which in turn will reduce the efficiency of filling.

The machine may have higher initial cost due to its special pump system.

Application

Pump filling machine is the most flexible and resilient machine that can better deal with liquids of all kinds encompassing thin liquids like water to thick and viscous fluids like shampoo, honey, lubricants and lotions etc.

Net Weigh Liquid Filling Machine

Net weight liquid filling machine is a unique machine that differ from other types on its characteristic to utilize weight-based filling. The machine is proficient in controlling the weight of product being filled into containers in order to ensure filling precision. For this purpose, it has a special feature of weight scale which remain alert during and after filling of liquid for checking the weight.

Benefits

• It supports all kinds of small to large containers regardless of their shapes and sizes.
• The machine is good for large filling volume ranging from 5L to 30L.
• Good for businesses that are concerned with the weight of product rather than volume.

Limitations

• It does not focus on the volume of material being discharged into the container.
• The machine is not applicable to low volume of liquids.

Application

Net weight filling machine is a perfect choice for filling the large volume of different types of liquids ranging from oil, sauces, and petrol to pesticides and paint etc.
