Edible Oil Filling Line
Modern Machinery supplies edible oil filling lines for olive oil, cooking oil, and vegetable oil. High-precision sensors enable dynamic online weighing during the filling cycle. This technology delivers accurate fills regardless of foam, temperature, or density changes. The line supports glass and PET bottles from 250 ml to 5 L.
What is an Edible Oil Filling Line
An edible oil filling line is a production system that fills, seals, labels, and packs cooking oil, olive oil, or vegetable oil into glass or PET bottles for retail and wholesale distribution.
Modern Machinery designs edible oil lines with multiple filling technologies in one machine. The system supports mechanical valve filling, volumetric valve filling, and flowmeter valve filling. High-precision load cells enable dynamic online weighing. The machine weighs each bottle during the filling movement. This method cancels the effect of foam, temperature, and oil density on fill volume. The result is consistent fill accuracy across every bottle. The line handles bottle sizes from 250 ml to 5 L. It works with both glass bottles and PET bottles. Quick-change parts allow fast switching between bottle formats.
Edible Oil Bottling Line Layout – 10 Machines in Sequence
The drawing below shows the standard arrangement for a Modern Machinery edible oil bottling line. Each machine feeds the next via conveyor.
Key machines in a Oil Production Line
Empty Bottle Depalletizer
This machine removes empty glass or PET bottles from pallets. It feeds bottles onto the conveyor in single file.
Clamp Conveyor
The clamping belt holds bottles gently during transport. This design prevents tipping and keeps the line running smoothly.
Edible Oil Filling Machine
The core of the line. It integrates mechanical, volumetric, and flowmeter valves. Dynamic weighing sensors measure each fill in real time for high accuracy.
Rotary Self-Adhesive Labeling Machine
This unit applies wrap-around or body labels to glass and PET bottles. The labeling head adjusts to different bottle diameters.
Automatic Sleeving Machine
The sleeving machine places shrink sleeves over the bottle neck or body. It handles PVC, PET, and OPS sleeve materials.
Electric Heat Shrinking Tunnel
This heated tunnel applies controlled hot air to shrink the sleeve tightly onto the bottle. The electric heating system offers precise temperature control.
Automatic Case Packer
This machine groups filled bottles into fixed patterns (e.g., 6×2 or 4×3). It loads the group into open cartons.
Automatic Carton Erector
The erector takes flat cardboard blanks. It folds and glues them into open boxes for the case packer.
Automatic Carton Sealing Machine
This unit folds the top flaps and applies adhesive tape. It outputs closed cartons ready for palletizing.
Automatic Robotic Palletizer
The robotic arm picks cartons from the conveyor and stacks them onto pallets in preset layer patterns.

Features of the Edible Oil Filling Machine
The filling machine supports mechanical valve, volumetric valve, and flowmeter valve. The operator selects the valve type based on the product viscosity and bottle size. This flexibility allows the same machine to handle different oil types without hardware changes.
High-precision load cells measure the fill weight while the bottle moves through the filling cycle. The system reads the weight in real time and adjusts the valve closure point. This method delivers accurate fills and removes the effect of foam, temperature, and oil density on fill volume
The weighing system includes dynamic compensation algorithms. The PLC reads the oil temperature and adjusts the density value during filling. This feature keeps accuracy stable across different ambient conditions and oil grades.
Each filling position has a proximity sensor. The sensor checks for a bottle before the valve opens. If a bottle is missing, the valve stays closed. This action prevents oil spills and reduces product waste.
The filling nozzles include an anti-drip cut-off mechanism. The nozzle closes immediately after each fill cycle. This design stops oil from dripping onto the bottle or conveyor, keeping the machine clean.
Modern Machinery supplies change kits for different bottle diameters and heights. Operators swap the bottle grippers, starwheels, and filling nozzle stroke. The complete change takes under 60 minutes.
The conveyor and grippers support both glass (rigid) and PET (flexible) bottles. The machine adjusts gripper pressure to avoid breaking glass or crushing PET. The filling nozzle height adjusts for different bottle neck profiles.
The filling bowl, pipes, and valve manifolds have CIP connections. Operators run a hot water and caustic detergent cycle between product changes. This design cuts manual cleaning time and prevents flavor carryover between oil types.
Project workflow from formula to installation
Product and Bottle Specification
Modern Machinery reviews your oil type (viscosity, density, temperature), bottle material (glass or PET), bottle dimensions, and cap type. We confirm the filling valve type and weighing calibration settings.
Factory Layout Drafting
Our CAD department drafts the plant layout. The drawing marks the 10 machine positions, conveyor lengths, and service connections (compressed air, electrical power, and drainage).
Assembly and Factory Acceptance Test (FAT)
We assemble the line in our factory. We invite you to run your actual bottles and oil samples. During the FAT, we measure filling accuracy, label placement, sleeve shrink quality, and overall line speed.
Installation u0026 Training
Our field service team handles the mechanical setup and electrical connection at your location. We then start up the line, calibrate the weighing system, train your operators, and provide the maintenance documentation.

Frequently Asked questions
What is dynamic online weighing and why does it matter for edible oil?
Dynamic online weighing measures the weight of each bottle while the filling nozzle is still active. High-precision load cells read the weight in real time and send the signal to the PLC. The PLC adjusts the valve closure point during the fill cycle. This method matters for edible oil because oil density changes with temperature. A volume-based filler would overfill or underfill as the oil warms or cools. Dynamic weighing fills by weight, not volume, so temperature changes do not affect accuracy.
What is the difference between mechanical valve, volumetric valve, and flowmeter valve?
Mechanical valve uses a fixed stroke to dispense a set volume. It is simple, durable, and works well for low-viscosity oils.nnVolumetric valve uses a piston or chamber to measure each fill. It offers better accuracy than mechanical valves for medium-viscosity oils.nnFlowmeter valve uses a magnetic or mass flow meter to measure the liquid passing through. It provides digital readouts and works best for high-viscosity oils and high-speed lines.nMD integrates all three types in one machine, so you can choose the best method for your oil.
How does the filling machine handle different bottle shapes (round, square, oval)?
The filling machine uses adjustable bottle grippers and starwheels. The grippers hold the bottle by the neck or body, depending on the design. The filling nozzle lowers to the correct height for each bottle profile. For square or oval bottles, we supply custom grippers that match the bottle contour. The change takes under 60 minutes with the quick-change kit.
Does the line support both glass and PET bottles on the same day?
Yes. The line supports both materials. Switching from glass to PET requires changing the gripper pressure settings (glass needs firm grip, PET needs lighter grip) and adjusting the filling nozzle height. We recommend a CIP cleaning cycle between material changes to remove any oil residue. The complete change takes about 60–90 minutes.
What is the filling accuracy of the dynamic weighing system?
The dynamic weighing system delivers filling accuracy of ±0.1% to ±0.2% of the target fill weight. For a 1 L bottle (approx. 920 g of oil), this means an error of less than ±2 g per bottle. The exact accuracy depends on the oil viscosity, fill speed, and bottle consistency.
