Edible Oil Filling Machine: Types, Benefits & Filling Line Guide

Edible oil is widely used in homes, restaurants, and food production. To handle different production needs, manufacturers need filling machines that are accurate, clean, and easy to operate.

This guide covers the common types of edible oil filling machines, how they work, their main advantages, and other basic information. Whether you are filling sunflower oil, palm oil, olive oil, or other edible oils, choosing the right machine can help make the filling process more efficient and stable.

What Is Oil Filling Machine?

Edible oil filling machine is equipment used to fill edible oil into bottles, jars, cans, or drums. It can be used for different products, including edible oil, olive oil, sunflower oil,sesame oil and so on

The machine helps control the filling volume, reduce spills, and make the filling process faster and more consistent. It is widely used in food, chemical, and lubricant production lines.

Advantages of Edible Oil Filling Machines

1.Easy to Clean

An edible oil filling machine is usually made with food-grade stainless steel. The parts that come into contact with oil are easy to clean and maintain, helping keep the filling process hygienic.

2.Automatic Operation

The machine can complete the filling process automatically. When connected with capping, labeling, and conveying equipment, it can also become part of a complete edible oil filling line.

3.Simple Control

Most machines use a PLC and touchscreen control system. Operators can easily set the filling volume, adjust the speed, and check the machine during production.

4.Accurate Filling

The filling system controls the amount of oil in each bottle, helping reduce overfilling, underfilling, and unnecessary product waste.

5.Flexible for Different Products

Filling volume and speed can be adjusted according to bottle size and production requirements. The machine can be used for sunflower oil, olive oil, soybean oil, palm oil, cooking oil, and other edible oils.

6.Higher Production Efficiency

Multiple filling nozzles can fill several bottles at the same time, making the machine suitable for medium- and high-output production lines.

7.Easy to Add to a Production Line

The machine can work with conveyors, capping machines, labeling machines, and other packaging equipment, making it easier to build or upgrade an edible oil bottling line.

8.Safe Operation

Safety guards, sensors, emergency stops, and other protection devices help keep the machine running safely during daily production.

What Are the Different Types of Edible Oil Filling Machines?

Different edible oils may require different filling systems depending on their viscosity, bottle size, filling volume, and production speed. The most common types of edible oil filling machines include piston filling machines, gravity filling machines, and gear pump filling machines.

1. Piston Filling Machine

A piston filling machine is a common choice for edible oil because it can handle liquids with different viscosities and provides stable filling accuracy.

The filling volume can usually be adjusted from around 100 ml to 5000 ml. Depending on production requirements, the machine can be equipped with 2 to 20 filling heads, with output ranging from about 720 to 7200 bottles per hour.

Piston fillers are suitable for products such as cooking oil, olive oil, sunflower oil, soybean oil, and other liquid food products. They can also be connected with bottle conveyors, capping machines, labeling machines, and packing equipment to form a complete filling line.

2. Gravity Filling Machine

 A gravity filling machine uses gravity to move liquid from the holding tank into bottles. It is mainly suitable for free-flowing, low-viscosity liquids.

The machine can normally handle filling volumes from 100 ml to 5000 ml, with several filling nozzles working at the same time. Filling speed can be adjusted through the PLC and touchscreen according to bottle size and production needs.

For edible oil applications, gravity filling is more suitable for oils with relatively low viscosity. Stainless steel construction also makes the machine easier to clean and suitable for food production environments.

3. Gear Pump Filling Machine

A gear pump filling machine uses a gear pump and servo motor to control the flow and filling volume. This type of machine is suitable for edible oils that require better control over filling speed and accuracy.

The filling volume and speed can be set directly through the PLC and touchscreen. Different filling modes, including bottom-up filling, can also be used to reduce splashing or bubbling during filling.

Gear pump fillers can handle different bottle sizes and filling volumes, making them suitable for sunflower oil, olive oil, cooking oil, and other edible oils. Common features include no-bottle-no-fill control, adjustable filling nozzles, recipe storage, and easy product changeover.

What Machines Are Used in an Edible Oil Filling Line?

An edible oil filling line can be simple or fully automatic. The basic line usually includes a filling machine, capping machine, and labeling machine. Other equipment can be added depending on the bottles and production output.

 1. Filling Machine

 The filling machine fills oil into the bottles. Different filling systems can be used for different oils and bottle sizes.

 2. Capping Machine

 The capping machine closes the bottles after filling. It can work with different cap types and bottle sizes.

3. Labeling Machine

 The labeling machine puts labels on the bottles. The machine type depends on the bottle shape and the label being used.

4. Conveyor

 The conveyor moves bottles from one machine to another and connects the whole line.

5. Bottle Unscrambler

 If empty bottles need to be fed automatically, a bottle unscrambler can be added before the filling machine.

 6. Coding Machine

 A coding machine can print the date, batch number, or other product information.

7. Packing Machine

 After filling, capping, and labeling, the bottles can be packed into cartons or shrink film.

For many edible oil factories, the main equipment is the filling machine, capping machine, and labeling machine. Other machines are added when needed.

How to Choose the Right Edible Oil Filling Machine?

When choosing an edible oil filling machine, you need to look at the actual filling requirements of your product and production line.

• Type of edible oil, such as sunflower oil, soybean oil, olive oil, palm oil, or cooking oil
• Oil viscosity
• Filling volume
• Required production speed
• Bottle shape and bottle size
• Level of automation required

Different edible oils and bottle sizes may need different filling methods. Choosing the right machine according to the oil viscosity, filling volume, and production speed can help keep the filling process accurate and stable.
