Types of Liquid Filling Machines
As mentioned in the introduction, the liquid filling machine is one of the most widely used devices in various industries and comes in different types. The type of machine is determined based on the desired liquid, its viscosity, and density. It can be said that the most critical stage in hygiene, food, cosmetics, and pharmaceutical factories is the filling process. Given the high importance and application of this machine, its presence in various factories is undeniable. However, before discussing the key considerations for purchasing a liquid filling machine, let’s first introduce its different types.
In a general classification, liquid filling machines are divided into three types based on their mechanism: pump mechanism, gravity mechanism, and piston-cylinder mechanism. Another method of classification is based on the characteristics of the liquid, which divides them into two categories: thick liquid filling machines and thin liquid filling machines.
Classification of Liquid Filling Machines Based on Characteristics and Viscosity
In this classification, there is a wide range of filling machines that are categorized based on the type of liquid and the machine’s functionality. For purchasing these machines, it is essential to accurately determine the physical properties of the desired liquid, such as density, concentration and dilution, viscosity, and viscosity variations with temperature, to select the best option based on these characteristics.
✅ Thick Liquid Filling Machine
These types of machines are used for transferring liquids with high concentration and viscosity and are classified into different categories. Some of these classifications include:
- Thick Liquid Filling Machine
- Rotary
- Inline Liquid Filling Machine
- Plastic Container Liquid Filling Machine
- Barrel Filling Machine
- Tube Filling Machine
- Can Filling Machine
- Vacuum Filling Machine
- Reciprocating Spray Filling Machine
- Spray Filling Machine
- Inline Spray Filling Machine
- Gravity filler
✅ Thin Liquid Filling Machine
In another classification of filling machines, we come to thin liquid filling machines, which are further divided into four categories.
- Gravity Liquid Filling Machine: This type is used for thin liquids that transfer by their own weight. Gravity fillers are commonly used in industries where the cleanliness of the transferred substance is highly important, such as the pharmaceutical and food industries. These machines have a simple operation and are also cost-effective.
- Overflow Liquid Filling Machine: This type is used for thin and semi-thick liquids, offering an advanced operation that covers the entire process from initial packaging and transfer to sealing the container.
- Tri-Block Liquid Filling Machine: This machine includes the final container washing, liquid transfer, and capping process, ensuring a complete and efficient filling operation.
- Mono-Block Liquid Filling Machine: This type combines only a capping and filling system, handling the secondary transfer process.
Types of Liquid Filling Machines Based on Mechanism
✅ Gravity Liquid Filling Machine
One type of liquid filling machine operates with a gravity mechanism, which is used for thin and fluid liquids. This machine is used for transferring lightweight liquids with low weight, and their transfer is facilitated by the force of gravity.
The operation of the machine is also very simple; you just need to fill its tank with the desired liquid. Then, press the nozzle at the bottom of the tank, allowing the liquid to be transferred to the final container or can, using its own weight and the force of gravity.
✅ Piston and Cylinder Liquid Filling Machine
These types of filling machines have a specific, precise operation and high-speed performance. They are used for transferring liquids in a specific volume or for transferring expensive liquids or pharmaceutical materials. With this machine, the most accurate volume of the desired liquid can be transferred in a very short amount of time.
✅ Pump Liquid Filling Machine
The pump-type liquid filling machine uses air pressure to transfer the liquid into the desired container. This machine is used for heavy liquids, as these liquids cannot be transferred by their own weight or gravity and require external pressure for transfer.
How to Choose the Right Liquid Filling Machine
In the following, we will discuss how to choose the right liquid filling machine based on the type of liquid. In this selection process, the concentration, dilution, and other physical and chemical properties of the desired material should be thoroughly examined, and the machine type should be chosen accordingly.
As we have seen, liquid filling machines are divided into two types based on liquid viscosity: thick and thin liquid fillers. If your production line falls under thick liquids, such as edible oil packaging, motor oil packaging, industrial oil production, dishwashing liquid packaging, gel production, hand and face cream packaging, sauce production, etc., you should choose and purchase thick liquid filling machines. In this selection, the final container volume and the desired filling speed are also important factors.
However, if your desired liquids fall into the thin liquid category, and you are working with products such as buttermilk, fruit juice, mineral water, disinfectant solutions, rose water, herbal distillates, etc., you should choose thin liquid filling machines.
Additionally, after selecting the type of machine based on viscosity, you can also choose it based on whether it is automatic or semi-automatic. Automatic liquid filling machines do not require human intervention, and the entire process is carried out automatically. However, their price is higher compared to semi-automatic liquid filling machines.
Applications and Features of Different Types of Liquid Filling Machines
As mentioned in the introduction, the application of this machine is vast across various industries, and it is commonly found in food, hygiene, and cosmetic factories. This machine is used for transferring and filling various liquids, powders, and even carbonated materials, covering a wide range of weights, from very low to very high.
With this machine, precise volumes of liquid can be filled into the desired container, which is especially crucial in the pharmaceutical, food, and cosmetic industries. The application of these machines is not limited to industrial use; they can also be used in workshop activities. For transferring liquids with high viscosity or stickiness that cannot be easily transferred, using filling machines with pressure or piston and cylinder mechanisms is very helpful. Additionally, these machines can be used for transferring materials that need to be handled in hygienic conditions and free from contamination.
Points to Consider Before Purchasing a Liquid Filling Machine
When considering the points for purchasing a liquid filling machine, the following factors are very important. In general, the key points to consider when buying a machine are determined based on the type of product and its chemical and physical characteristics.
✅ Liquid Viscosity
The viscosity of the liquid is one of the key factors in choosing the appropriate machine. Based on viscosity, liquid filling machines are divided into two types: one for transferring thin liquids and the other for thick liquids. For transferring syrups, sauces, and similar substances, thick liquid filling machines are used, while thin liquid filling machines are used for water, detergents, disinfectant solutions, and similar products.
✅ Filling Method
The filling method is another important factor in choosing a liquid filling machine, determined by the mechanism. One of these mechanisms is based on the filled volume, and another is based on the filled level. In the filled volume mechanism, each bottle is filled with a specific volume of the desired liquid, which is determined by the container size and shape. In the filled level mechanism, different bottles are filled to a specific liquid level. In this mechanism, the containers may have different volumes, and their shapes can vary.
✅ Speed
Another point to consider when purchasing a liquid filling machine is the filling speed. This refers to how many containers are filled per hour or per minute.
✅ Container Type
The type of container or bottle is another important factor in choosing a filling machine, which is determined based on the material of the container, such as glass, plastic, metal, or other types.
Summary
The liquid filling machine is one of the most practical devices in the food and pharmaceutical industries, hygiene products, disinfectant solutions, herbal distillates, and more. These machines are categorized into different types based on the viscosity of the desired liquid, and certain factors must be considered when purchasing and selecting the right one. Some of these factors include the viscosity of the material, the filling method, the filling speed, and the type of container or bottle.
