    Keep on reading to know the primary difference between different filling machines. Following are some types based on filling, application, and design.

    Based on Filling Technique

    Some fill to a level, while others fill by volume. Most of the time, both these techniques will work for the same products. However, both give different benefits for packagers, but outsiders will not comprehend them easily. People who are not familiar with filling machines will only look at the appearance of bottles rather than their volume.

    1. Volumetric Fillers

    Volumetric Filler

    They fill the bottles with the accurate volume and not by level. Therefore, each bottle may not look the same due to variations in interior container volumes. It can be noticeable when inconsistent levels of the product are added from bottle to bottle. It can become an issue in clear containers. They include Gravity-fed filer, piston, and pump fillers.

    However, their capability to fill different viscous products from water to heavy oils makes them unique. They apply to any container and work at high speed. But they are a bit expensive for small-scale industries.

    2. Fill To Level Fillers

    They focus on equal levels of oral liquids in all the containers. This method is cost-effective and results in an attractive appearance. Most liquid-level machines include pressure overflow fillers.

    Filling Level-Photo

    Overflow fillers fill at a fast rate and can handle low and medium viscous liquids. In case of any remaining product in the filling tubes, it is forced back into the tank. Therefore, ensuring no fluid overflow and spillage.

    Based on Application

    Following are the types of oral fillers on their working principle and application.

    1. Overflow Fillers

    They work on the fill-level principle that requires constant fill levels.

    Overflow fillers use a nozzle that permits a level on each container. As soon as the liquid reaches its degree in the container, it overflows and returns to supply. Thus, they are ideal for filling lower viscous liquids in transparent containers.

    2. Net Weight Fillers

    Net weight machines use a weight scale to have consistent fill levels. Both automated and semi-automated types are applicable. They monitor the weight of the liquid as it is filled into the bottle. A bulk supply tank load the products. The accuracy of weighing and filling liquid is 5-30 kg. Each container has pre-set weight.

    Gravity Fillers work with a time-based system. They have a tank above the filling heads to supply liquids. It is kept above to allow gravity to assist in the procedure. When the container is under the filling heads, the valve opens, and it will supply the container with the given pre-defined amount. The valves will close after their pre-fixed time and cut off the supply.

    It is one of the most cost-effective machines among all other filling machines. Single heads, as well as multi-heads, can function well once the system is balanced. They are appropriate for liquids thin viscosity like water. However, they fill a limited range of products only.

    4. Piston Fillers

    Piston Fillers-Photo

    They work according to the volumetric filling technique. Check-valve piston and rotary piston fillers are used commonly. They can handle thicker products such as batters, pastes, and aerated fluids.

    Piston fillers contain pistons and cylinders for more precise volumetric filling. They can function with many different-sized cylinders. When the piston pulls out of the cylinder, the oral liquid gets transferred in it. Now when the cylinder is complete, the piston again enters it. Thus, pushing the product to enter into the bottles.

    The reason why it is more desirable than the pump fillers is that it also handles granular products. However, they take a longer time to execute the changeover and cleaning.

    5. Pump Fillers

    Pump Fillers-Photo

    Pump Fillers-Photo Credit: youtube

    They work using the volumetric principle rather than relying on gravity. Rotor, lobe, and gear pumps are various types of pumps.

    Pump fillers pass the product into the waiting bottles using different pumps. They also offer customization fillings such as pulse and time-based fills. Time-based fills allow the pumping of products in bottles for a pre-fixed time. For more accurate fills, adjust each fill head individually. For example, in Pulse-based fillers, a pulse may include an entire or half turn of the gear with a gear pump. This volume allows a bit better volumetric accuracy over the time-based fill.

    The pumps give an extra boost in moving the liquids. Moreover, versatility makes them suitable for filling a wide range of drinks. Thus, they are helpful for thick fluids, and the content of fill volumes is more excellent.

    Based on Design

    Apart from application and filling techniques, oral liquid filling machines are available based on designs.

    Q7.Explain the working principle of Oral Liquid Filling Machine?

    Working Principle-Photo

    Working Principle-Photo Credit: jiji

    The working principle of the oral liquid filling machine is similar to liquid fillers, but the machinery is different. Oral Liquid appliance needs bigger pump whereas eye drop fillers need a small and more accurate pump.

    In the automatic production line, the bottles pass through a power conveyor system to the filling station. Here, a filling nozzle supplies the oral liquid product present in the hopper to the container. Different types of machines have other working principles such as fillers work by gravity, atmospheric pressure, and weight scale.

    Here are the steps involved in the working of oral liquid filling.

    1. Power Transmission

    First, the motor transfers the power to the worm wheel via the lifter. Then this worm wheel passes the control to the dial shift, the filling part, and the rolling head through the gears. They all work synchronously, and the force gives to the bottle injecting gadget via bevel gear.

    2. Filling Part

    A large dial wheel sends these oral liquid bottles to the transition wheel. Here, it further moves them to the timing belt to run ahead at a constant speed. The needle in the bottle mouth runs additionally for tracking filling synchronously. The filling needles give an anti-foaming effect and rise as the liquid level rises.

    3. Covering Mechanism

    This system consists of a cover rail, cover head, and cover mechanism. It works on the principle of electromagnetic spiral vibration.

    4. Rolling Head

    Here, the oral liquid bottle shifts into the rolling head turntable. Here the rolling knives centered on the bottle open. They rotate with the turntable forwardly, pressing the lid. By taper sleeves, they undergo rolling. Then they leave the cap and go back to the original position.

    Most of the oral liquid fillers work in higher pressure. As in pressure filling, the oral liquid flows into the bottle according to its weight. It happens when the fluid storage pressure becomes equal to the atmospheric pressure of the bottle. Automatic fillers are easy to operate, and they fill the exact amount of liquid into containers. One function is to automatically stop the filling procedure when there is no bottle available on the conveyor.

    Different Categories of Oral Fillers Based On Working Principle

    You can further divide Oral liquid fillers into the ordinary filling machine, pressure filling machine, and vacuum filling machine.

    The ordinary oral liquid Filling machine works on the principle of gravity. The oral liquid fills due to its weight into particular bottles. You need to observe special needs to maintain the viscosity and gas bearing of the fluids. Examples are milk bottles and grapevines.

    In Vacuum oral liquid filling machine, the atmospheric pressure is higher than the air pressure in the bottles. Also, it works excellent for liquids with high viscosity, such as syrup, oil, and wine.

    Pressure oral liquid filling machines require higher or equal pressure than atmospheric pressure. In Equal pressure filling, the oral fluid storage pressure gets equal to the bottle pressure. Therefore, the liquid flows by its weight. On the other hand, higher pressure filling machine operates by the pressure difference.

    Q8. What are the other liquid fillers along with Oral Liquid Filling Machine present in market?

    Oral liquid fillers are helpful for many kinds of edible liquids. But other than oral liquid fillers, there are many more liquid filling machines, primarily for chemical packaging lines. Such fillers are helpful for chemical products like cleaning supplies, acid, corrosive products, paints, industrial and agricultural chemicals, cosmetic products and petroleum products, etc. They have unique capabilities to handle safely and package chemical products.

    2. The viscosity of Oral Liquids

    What is viscosity? It means the ability of the oral liquids to flow freely. Each oral fluids have different viscosities. For instance, water has a thin consistency and shows less resistance in flowing. Thick or high viscous liquids don't move freely, for example, honey.

    Each oral liquid requires a different type of filling machine. Therefore, identifying the correct one according to your product is the first thing to consider.

    • Low Viscous Oral Products

    Low Viscosity Product

    Oral liquids which flow quickly require overflow fillers and Gravity Fillers. They work appropriately for frothy or low-viscous oral liquids such as water, vinegar, and syrups. Gravity fillers find their use in food processing companies to fill alcohols, milk, juice, and soda. Other than oral liquids, ink and paints can be served.

    • High Viscous Oral Products

    Such oral liquids require pump and piston fillers for packaging. Pump fillers and rotary piston fillers are special for very thick products requiring extra speed to move. Piston fillers are ideal for creamy and chunky products. Other than oral liquids, they are also valuable for packaging cosmetics creams, waxes adhesive, heavy shampoo gels, and heavy oils.

    3. Filling Rate

    Another important determinant is the number of filled bottles per hour.

    part of oral liquid filling machine 2

    In semi-automatic oral fillers, the filling completes at a slower rate. Manual labor is required for bottle replacement and then removing the filled ones. In comparison, automatic filling machines package oral liquids at higher speeds.

    If your machine is willing to fill more bottles per minute, you will reach your production demands faster.

    4. Capability for Different Volumes of the Liquid

    Fill volume determines the level at which your vessel fills. You have to choose whether you want liquid level filling machines or Volumetric filling machines.

    Liquid level fillers concern the level of oral liquid on the container. The nozzle allows the fluids to enter a bottle until they reach the desired level. They ensure no overflowing and keep the fill at the same level when the cycle is completed. It is helpful for clear containers. You must prefer them if uniformity is essential.

    Accurate in Every Bottle

    Volumetric filling machines are concerned with an accurate volume of liquid in each container. The need for additional instruments for timing, calibration, and balance makes them relatively expensive.

    Not everyone knows about filling techniques. The fluid may appear at different levels due to inconsistencies in the volumes. Imagine bottles each on the shelf with different liquid levels in a grocery store. Although the quantity is the same, the customer will prefer a high-filled bottle because customers don't understand this technique and think they are cheated.

    It's your choice whether you would like the bottle's volume in the bottle to be the same or whether all containers need to LOOK the same.

    5. Type of Container

    The kind of bottle or container being used is also an essential factor to consider. For clear containers, overflow fillers are a good choice. They fill each bottle to the same level irrespective of small variability in the inside volume of the container.

    Another thing to know is the material you are using. Commonly used materials are glass, plastic, and aluminum. Each of them requires a different filling technique.

    6. Shape of Container

    The Size and shape of the container also influence the choice of nozzle and machine in packaging. If your container is wide, don't go for the fillers that grip from the side of the bottles. If the container does not have a standard lid, then automatic oral fillers are not appropriate. It is because they grab bottles from the top.
