What is a thick liquid filling machine?
Thick liquid filling machines are among the most widely used machines in factories and production facilities. These machines are used to fill thick liquids into various containers. By thick liquids, we mean liquids with high viscosity and density, such as jelly, oils, sauces, honey, and similar products. Filling these types of liquids must be done accurately and without errors, as any incorrect settings can result in unacceptable mistakes and customer dissatisfaction. If your production capacity is high, it is better to use an automatic thick liquid filling machine, which fills a specified volume into each container and increases the efficiency of production lines.
It also increases product quality, and due to the automation of the machine, the number of operators is reduced, thus lowering costs. However, if your production capacity is low, it is better to use a semi-automatic machine. Keep in mind that if the number of nozzles in the machine exceeds two, it is not cost-effective for the buyer. This is because an operator must be assigned to each nozzle, and the factory’s costs over the course of a year will exceed the cost of purchasing an automatic machine. Radan Machine recommends that if the machine requires more than two nozzles, it is better to opt for the automatic model.
The application of thick liquid fillers
Thick liquids with high viscosity are filled using a thick liquid filling machine. In these machines, the injection occurs from the bottom of the containers. This method not only ensures the container is filled completely but also prevents the formation of bubbles. Typically, thick liquid filling machines are used in the food industry for packaging various products such as jams, yogurt, chocolate, tomato paste, and more, in glass, metal, and plastic containers. One of the most commonly used machines in this field is the honey filling machine.
Other industries that use thick liquid filling machines include the chemical industry for filling various detergents, dishwashing liquids, oils, and more. In the pharmaceutical industry, these machines are used for filling various syrups, acetone, and other liquids. Below, we have listed three machines and their respective industries for you:
honey filling machine
Honey is a thick liquid that becomes a thinner and more fluid consistency through heat in the machine, making the filling process easier. In this machine, there is no need for an operator as all tasks are done automatically. To purchase the best honey filling machine at the most competitive price, you can visit the reputable company Radan Machine and make your purchase directly through their website.

Oil filling machine
Oils are available in the market in two categories: edible and industrial. To package them, edible oil filling machines and motor oil filling machines should be used. The options installed on the machine affect its price. Oil is highly viscous, and a specific mechanism must be used to fill containers to increase work speed and prevent waste. In these machines, the higher the motor power, the more nozzles can be used.
Dishwashing liquid filling machine
One of the most widely used thick liquid filling machines in the hygiene industry is the dishwashing liquid filling machine, which employers can purchase at the most suitable price. This filler is designed and manufactured by Radan Machine in various sizes and capacities, which speeds up product production. The dishwashing liquid machine is equipped with nozzles, and the number of nozzles depends on the machine’s volume and capacity, ranging from a single nozzle up to 10 nozzles.
Food Industry: sauces, date syrup, tahini, honey, chocolate, yogurt, and more
Pharmaceutical Industry: various syrups, lotions, and more
Cosmetic and Hygiene Industry: nail polish, acetone, shampoo, dishwashing liquid, and more
Chemical Industry: motor oil, grease, petroleum jelly, and more

Types of thick liquid filling machines:
The thick liquid filling machine is used for filling liquids with high viscosity, such as honey, tahini, chocolate, etc. This machine is designed and produced in various sizes and dimensions according to the client’s needs in customized models at Radan Machine. Different types of filling machines are manufactured based on three mechanisms, and in the following, we will examine the types of thick liquid filling machines.
Piston Cylinder Liquid Filling Machine
In this machine, liquids are filled into containers based on the capacity of the cylinder, meaning the container volume is adjusted according to the machine’s volume. The filling mechanism of this machine is based on a piston-cylinder system. The cylinder in the machine allows for smooth movement of thick liquids such as honey, grease, vaseline, chocolate spread, and more. Some liquids require heating before being filled by the machine so that they can flow more easily and speed up the filling process.
After the filling process, the product is conveyed by a conveyor belt to the other packaging machines, such as the capping machine, labeling machine, date coder, and so on. One of the advantages of the piston-cylinder thick liquid filling machine is its high performance and reasonable price compared to more expensive filling machines. It is important to note that, in addition to high-viscosity liquids, this machine can also fill low-viscosity liquids that do not foam during filling.
pump liquid filling machine
This machine is suitable for filling thick liquids with high viscosity, such as grease, cream, chocolate, wax, paste, and more. While the filling process using a pump may reduce the precision of the machine, the mechanism of the piston-cylinder system enhances its accuracy. The pump-type liquid filling machine can be ordered in both automatic and semi-automatic models. In the semi-automatic version, an operator is required, whereas in the automatic version, all tasks are performed by the machine itself.
Rotary Liquid Filling Machine
The Rotary Viscous Liquid Filling Machine is used for filling thick liquids such as cream, yogurt, cheese, and more. This machine operates automatically, and when ordering, the size of the container to be filled should be considered, as the machine molds are designed based on the container size. The working process of this machine is as follows: the mold is placed in the machine, then the material is injected into the containers via a nozzle with a piston-cylinder mechanism, and the product is moved outside the machine by a pneumatic arm. One of the advantages of this machine is the small space it occupies.
What is meant by high viscosity or thickness?
Viscosity refers to the resistance of a substance or liquid to flow. Nowadays, the fluidity of various liquids, gels, and even solids is tested and measured to specify a certain amount, which can then be used for various applications. Therefore, the first criterion for determining the type of liquid filling machine is the viscosity and density of the materials. If the density of the material is high, a thick liquid filling machine should be used, such as for grease, date syrup, jam, and various oils, which are examples of high-viscosity liquids.
When the viscosity and concentration of the materials are low, the liquid is fluid and suitable for a liquid filling machine designed for thin liquids, such as water, juice, and degreaser. For filling thick liquids, a mechanism with high sensitivity should be used, as even the smallest mistake in settings and design can cause irreparable problems. Therefore, it is better to use a piston cylinder liquid filling machine because, in addition to speed, it offers high accuracy for filling liquids under one liter.

Manufacturing of thick liquid filling machines
The manufacturing of thick liquid filling machines varies based on the required volume and the external design of the machines. For example, a detergent filling machine differs in model and size from a honey filling machine. Radan Machine Company designs and manufactures the machines based on the type of product, container size, and production volume. The company is ready to offer services and plan for the design and construction of industrial machinery.
