Small Automatic 3-in-1 Filling Machine for Milk Oil Water Fruit Juice for Small Businesses 500ml Glass Bottle Core Motor Gear

The Small Automatic 3-in-1 Filling Machine is designed for small and medium-sized businesses that need a compact, reliable, and flexible solution for liquid bottling. Suitable for milk, water, fruit juice, oil, beer, cream, and other liquid products, this automatic filling system can handle both glass and plastic bottles in different filling volumes, including 100ml, 200ml, 300ml, 400ml, 500ml, and 1L.

With electric drive, PLC control, precision components, and a filling accuracy of approximately ±2mm, the machine helps manufacturers improve production efficiency while maintaining consistent filling performance.

What Makes This 3-in-1 Filling Machine Suitable for Small Businesses?

For a small beverage or liquid-product factory, investing in a large production line is not always practical. This 3-in-1 filling machine combines multiple bottling functions into one integrated system, helping save floor space and simplify production management.

The machine is designed for automatic operation and can be configured according to the customer's bottle size, filling material, and production requirements. Its relatively compact design makes it suitable for factories with limited workshop space while still providing the automation needed for regular production.

It can be used in industries such as:

• Drinking water and purified water

• Milk and dairy products

• Fruit juice and other beverages

• Edible and liquid oils

• Beer and other liquid drinks

• Cream and selected cosmetic products

• Other low- to medium-viscosity liquid products

How Does the Automatic 3-in-1 Filling Machine Work?

The machine integrates key bottling operations into one production system, reducing the need for operators to manually transfer bottles between individual machines.

Empty bottles are first positioned and prepared for filling. The filling system then delivers a controlled quantity of liquid through the filling nozzles. After filling, the bottles can proceed to the next stage of the packaging process.

PLC-based control allows operators to manage the main operating parameters more conveniently. Depending on the production configuration, the system can be connected with additional equipment such as capping machines, conveyors, water treatment systems, labeling machines, and packaging systems.

This makes it possible to build a complete bottling solution rather than relying on a standalone filling machine.

What Filling Volumes and Bottles Can It Handle?

The machine supports several commonly used filling volumes, including 100ml, 200ml, 300ml, 400ml, 500ml, and 1L. This range gives small manufacturers greater flexibility when developing different bottle sizes and product specifications.

Both glass and plastic bottles can be considered for the application. For businesses mainly using 500ml glass bottles, the filling system can be configured around the actual bottle dimensions and production requirements.

Before production, bottle samples should be provided to the manufacturer so that the filling and handling components can be properly matched.

What Are the Main Advantages of the Machine?

High Filling Accuracy

Consistent filling volume is important for beverage, dairy, water, and other liquid products. The machine is specified with an approximate filling accuracy of ±2mm, helping maintain uniform filling results during continuous operation.

Actual filling performance can vary depending on the liquid characteristics, bottle design, filling volume, and machine configuration.

Automatic PLC Control

The automatic control system reduces manual operation and makes it easier to manage the filling process. PLC components are used to coordinate the machine's operating functions and provide more stable production control.

This is particularly useful for small businesses that want to increase output without significantly increasing labor requirements.

Durable Core Components

The equipment uses key components such as a motor, pump, pressure vessel, PLC, gear, bearing, and gearbox. Proper selection and maintenance of these components are important for maintaining stable operation over long production cycles.

The machine is electrically driven and can be configured for 220V or 380V power according to the customer's factory requirements.

Flexible Liquid Applications

One of the major advantages of this type of filling equipment is its application flexibility. It can be used for different liquid products rather than being limited to a single beverage.

For manufacturers producing several product categories, this flexibility can make equipment utilization more efficient. However, liquid viscosity, foaming characteristics, temperature, and hygiene requirements should be considered before selecting the final filling configuration.

Is It Suitable for 500ml Glass Bottle Production?

Yes. The machine can be used for 500ml glass bottle filling applications, provided that the bottle dimensions, neck size, product characteristics, and required production capacity are confirmed before manufacturing.

Glass bottles require stable positioning and careful handling during automated filling. The bottle structure, neck diameter, and overall height can affect the selection of bottle handling and filling components.

For this reason, customers should provide bottle drawings or physical samples when requesting a customized configuration.

How Can It Be Integrated into a Complete Bottling Line?

Although the 3-in-1 filling machine can perform the core filling operation, many manufacturers need a complete production line.

The equipment can be combined with upstream and downstream systems such as:

• Water treatment equipment

• Liquid preparation and mixing systems

• Bottle washing or rinsing equipment

• Filling and capping systems

• Conveyor systems

• Labeling machines

• Date coding equipment

• Secondary packaging systems

For example, a small drinking-water producer can connect water treatment, bottle preparation, filling, capping, labeling, and packaging equipment to create a complete production process.

For customers producing carbonated beverages, a dedicated carbonated beverage filling machine and suitable carbonation system should be selected according to the beverage formulation and production requirements.

Why Is After-Sales Support Important?

For small businesses, unexpected equipment downtime can directly affect production schedules. Therefore, technical support is an important part of the equipment selection process.

Available service options include video technical support, online support, field installation and commissioning, operator training, maintenance and repair services, and spare-parts support. The equipment is also supplied with a one-year warranty according to the stated product terms.

Before placing an order, customers should confirm installation conditions, electrical requirements, spare-parts availability, operator training, and the scope of technical support with the supplier.

Who Is This Filling Machine Designed For?

This machine is particularly suitable for:

• Small beverage manufacturers

• New bottling businesses

• Dairy processing companies

• Drinking-water producers

• Fruit juice manufacturers

• Small food-processing factories

• Liquid product manufacturers

• Businesses expanding from manual to automated filling

It is a practical option for companies that need automated production but do not yet require a very large industrial filling line.

Why Choose a Professional Filling Equipment Supplier?

Choosing the right supplier involves more than checking machine specifications. Manufacturing experience, component quality, factory testing, technical support, installation assistance, and customization capabilities all affect the long-term performance of filling equipment.

What Should You Confirm Before Ordering?

Before purchasing a small automatic 3-in-1 filling machine, it is recommended to confirm the following information with the manufacturer:

1. Product type and liquid viscosity

2. Required filling volume

3. Bottle material and dimensions

4. Bottle neck size

5. Desired production capacity

6. Required filling accuracy

7. Power supply at the installation site

8. Required filling and capping functions

9. Available factory space

10. Installation, commissioning, and after-sales requirements

Providing accurate technical information at the beginning helps the manufacturer select the correct filling components and create a more suitable solution.

Conclusion
