With the significant advancement of science and technology, we are now witnessing the obsolescence of traditional packaging methods and the increasing popularity of various machines in product packaging industries. One such machine is the liquid filling machine, which has many applications in the production line, speeding up the manufacturing process and providing the necessary sanitary conditions for the factory. As you know, manually filling liquids comes with many challenges, and even if done under isolated and sanitary conditions, there is still a possibility of contaminants entering the product. The most commonly used types of liquid filling machines in production lines are those for thick and thin liquids. In this article, join us as we explore the differences between thick and thin liquid filling machines.
What is a liquid filling machine?
A liquid filling machine is an automatic and self-operating device that allows various liquids to be filled into glass containers and paper bags. This machine minimizes human intervention in the production process. Semi-automatic versions of this machine are also available in the market, which have specific applications based on the conditions of different liquids. Generally, different models of these machines are used depending on the type of liquids and the sanitary conditions required for filling them. For more information about purchasing a liquid filling machine, you can refer to the relevant link.
Types of Liquid Filling Machines
Liquid filling machines come in various types, each serving a specific purpose. To help familiarize you, our dear audience, with the different types of liquid filling machines, we will explain the thick liquid filling machine and the thin liquid filling machine in the following section:
Thick liquid filling machine
The thick liquid filling machine is one of the models of filling machines used in packaging industries to fill and transfer thick liquids or liquids with high viscosity (high resistance to flow). Viscosity or high thickness refers to the fluid properties of materials, which is the primary and most important factor in choosing the type of liquid filling machine. Examples of liquids that can be filled using this machine include edible jelly, various thick syrups, concentrates, and different oils. The most significant difference between thick and thin liquid filling machines is the absence of gravity force in the injection process.
liquid filling machine for thin liquids
The thin liquid filling machine is another type of filling machine, usually made with a volumetric or gravity system, and in some cases, a cylinder-piston system is used in its production. Like the thick liquid filling machine, this device is produced in both automatic and semi-automatic types. As the name suggests, the thin liquid filling machine is used for filling liquids such as water, herbal extracts, rosewater, juices, thinners, antifreeze, and other thin liquids.
It is worth mentioning that this is just one way to categorize liquid filling machines. These machines can also be classified into three types based on their mechanism and operation: gear pump, overflow, and piston cylinder, each having its own specific applications
Features and applications of thick liquid filling machines
As mentioned, the thick liquid filling machine is one of the types of filling machines, and the main difference between thick and thin liquid filling machines lies in the lack of using gravitational force for the injection process. The term “thick” is used to describe liquids with high viscosity or resistance to flow (such as ketchup, mayonnaise, honey, oil, etc.). One of the most commonly used types of thick liquid filling machines is the honey filling machine. These machines are also used in chemical industries for filling dishwashing liquids, detergents, motor oils, medicinal syrups, and more.
One of the most commonly used thick liquid filling machines is the RPF 40 automatic servo motor piston cylinder filling machine, which, without the need for a skilled and experienced operator, can fill various corrosive, hot, foaming, and pulp-containing liquids. You can now order this machine through the Radan Machine website.
Features and Applications of the Liquid Filling Machine for Thin Liquids
The most significant difference between thick and thin liquid filling machines is that thin liquid filling machines are used for packaging liquids with a viscosity lower than oil. If you intend to package products such as medicinal syrups, various bleach liquids, liquid cosmetic products like toner, and similar items, you should consider purchasing a thin liquid filling machine to significantly improve your production line process and reduce the likelihood of errors.
These machines are used for filling various thin edible liquids, detergents, solvents, and chemical liquids and can be utilized in various industries.
Differences Between Thick and Thin Liquid Filling Machines
Now that we know the features and applications of thick and thin liquid filling machines, we can discuss the differences between them:
- In the construction and design of thick liquid filling machines, a cylinder and pump are used to facilitate the smooth and easy movement of liquids. This feature allows honey or any other thick substance to be easily transferred into containers. The actuator used for this process is produced in two types: pneumatic and hydraulic.
- The difference between the two is that in a pneumatic actuator, an air compressor is used to transfer the jack and actuators. If the machine is of the pump type, no piston is used in its construction, and all transfers are carried out through a pump.
- Additionally, the type of filling machine used for filling containers with liquids such as pharmaceutical and food products, juice, mineral water, etc., can have a single nozzle or between two to six nozzles, with the possibility of adding more nozzles if needed.
Final Words
The packaging industry is one of the most widely used industries, utilizing various machines to carry out the packaging process in the best possible way. Each of these machines has its unique features and applications, contributing to improved packaging quality. In this article, we aimed to explain two of the most commonly used packaging machines—thick and thin liquid filling machines—and examine the differences between them.
