Liquid Syrup Filling Machine: A Complete Guide

One of the most important principles to consider when packaging pharmaceutical products, such as syrups, is maintaining complete hygiene, preventing hand contact with liquids during packaging, and avoiding contamination. Therefore, manual processes should be minimized during the packaging of these liquids. This is why such products are filled using specialized machines, known as liquid syrup filling machines. In this article, stay with us as we explore what a liquid syrup filling machine is and what advantages it can bring to your business.

What is a liquid syrup filling machine?

As you know, liquid filling machines are equipment used in production lines for packaging various liquids. These machines have the ability to fill liquids into containers without manual contact, significantly improving the productivity and efficiency of the production line. The medicinal liquid filling machine is also one of the types of liquid filling machines, specifically used in the production of liquid medicines.

These machines can be ordered according to bottle size, and additional equipment such as capping machines and conveyors (for moving containers) can be included. The most important aspect of these machines is ensuring they meet the necessary standards and have a hygienic system, as medicines must be free from any contamination.

Advantages of a Liquid Syrup Filling Machine

Liquid syrup filling machines offer many benefits for businesses, one of which we previously mentioned: performing the packaging process of medicines without hand involvement and in the most hygienic possible manner. Below, we will discuss other advantages of these machines:

Packaging products in a consistent and reliable manner

Using a filling machine eliminates uncertainty from the packaging process. The consistency and reliability that cannot be achieved with manual filling of bottles or containers can be easily attained with a liquid syrup filling machine.

High speed

The most prominent advantage of using automatic packaging machinery is their ability to increase speed. The use of electric conveyors and multiple filling heads ensures that production is not only faster but also continuously executed.

Versatility

Many companies use several types of bottles for a single product. Some companies also need to package multiple types of products. In most cases, a filling machine can be customized to handle all of a company’s bottles and products.

Ease of use

Automatic liquid filling machines are equipped with a PLC and an operator interface, allowing the operator to enter the required times and quantities for completing each cycle through their touch screen.

Growth potential

Automatic packaging machines are designed with the future of production in mind, and they should be built in such a way that customers can add their desired equipment and upgrade the machine if necessary.

Types of liquid syrup filling machines

Now that we know the advantages of a liquid pharmaceutical filling machine, it’s time to get familiar with the different types of these machines. Liquid syrup filling machines come in various types, and the appropriate machine can be selected based on the product specifications:

• Gravity Liquid Syrup Filling Machine

This type of device is more suitable for thin liquids whose viscosity does not change at room temperature or with product batch variation. Its operation is such that the pump of the device transfers the product into the tank located at the top of the machine, and the nozzles, over a set period, dispense a specific amount of the product into the bottles by gravity. The gravity liquid syrup filler is used in companies that produce mineral water, milk, juice, soft drinks, bleach, glass cleaner, alcohol, and diluted acidic liquids.

• Overflow liquid syrup filler

This type of device is an economical and cost-effective option for filling various thin liquids, semi-thick liquids, and products with solid particles. The overflow filler has nozzles that create the pathways for product intake and air exit. The inner layer pours the product into the bottle, while the outer layer removes the air and excess liquid from inside the bottle. In this way, the bottles are filled to the same level regardless of the amount inside them.

The overflow liquid filler is used for filling products such as medicinal syrups, water, shampoo, glass cleaner, bleach, disinfectants, and acidic liquids, and is considered an ideal solution for foaming thin liquids.

• Piston liquid syrup filler

But what is the piston mechanism in a medicinal liquid syrup filling machine? These devices are used for both thin and thick liquids, especially for thick liquids with high viscosity and solid particles. The operation of this device is such that the piston is pulled back inside the cylinder, filling the cylinder with the product. Then, with the forward movement of the piston, the product is directed into the container.

The piston liquid syrup filler is primarily used for filling thick and semi-solid materials such as various creams, shampoos, toothpaste, honey, sauces, syrups, and oils, in addition to thin liquids.

• Peristaltic pump liquid syrup filling machine

This device is used for filling small vials with high speed and accuracy and is widely used in the pharmaceutical and cosmetic industries. When the machine is turned on, the pump motor starts rotating, and the alternating rotation of the pump and its contact with the outer layer of the silicone hose causes the product to be transferred through the inner layer of the hose (at the set amount) into the bottle.

The peristaltic pump liquid syrup filling machine, due to its high weighing accuracy and very low product loss, is used for filling expensive liquids and products with low dosing (e.g., 1 milliliter).
