Packaging Line Project

Low-Cost Semi-Automatic Sauce Filling Machine

Designed for startups and small sauce producers, this compact machine supports small-batch filling of smooth, particle-free sauces with a low initial investment.

The operator positions each bottle and starts the fill cycle with a foot pedal. For foaming products, the nozzle can stay close to the liquid surface as the bottle is lowered to reduce splashing and foam.

Changeover Basis
Sauce-specific cleaning and filling-setting reset

The reference output is for LEKA-FLsemi-CLB02. Actual output depends on sauce viscosity, foam behavior, fill volume, operator speed, manual handling, and cleaning frequency.

Customer Requirements

What the customer needed the line to handle and achieve.

The customer needed a practical filling setup for 500 mL batches of smooth, particle-free sauces, with stable output and simple changeover between recipes.

Customer Challenge and Project Goal

The production constraints that shaped the proposed solution.

Production Challenge

Typical challenges included a limited startup budget, small order sizes, inconsistent hand filling, sauce foaming, dripping, and frequent recipe changeovers.

Required Improvement

The proposed machine replaces hand pouring for short runs and improves repeatability through controlled filling settings and sauce-specific cleaning.

Why This Configuration Was Selected

How the product, package and output target influenced equipment selection.

This configuration balances startup budget, small batch size, sauce flow behavior, and simple operation. The selected 5–5,000 mL filling range includes the 500 mL bottle used in this project.

It reduces hand-pouring errors while keeping cleaning and recipe changeover manageable. Final settings are confirmed with actual sauce and package samples.

Complete Line Configuration

The machines and functions included in the proposed packaging process.

Machine Configuration Model Production Use Project-Specific Requirement
Bottle Staging Table Project-configured Holds clean bottles for manual loading. Confirm bottle size, stability, neck opening, and batch identification.
Double-Head Sauce Filler LEKA-FLsemi-CLB02 Fills the two sauces in the planned 500 mL batch format. Test each sauce to confirm viscosity, foam behavior, temperature, particle-free condition, nozzle cut-off, seal compatibility, and cleaning.
Manual Cap Application Project-configured Bottle caps are placed and tightened by the operator. Confirm cap type, bottle-neck fit, and any hand or torque tool.
Manual Labeling and Coding Project-configured Labels and batch codes are applied separately. Confirm label position, coding area, and recipe changeover checks.
Finished-Bottle Inspection Project-configured Checks fill appearance and closure before packing. Define fill, foam, leakage, cap, label, and traceability checks.

Quality Control and Project Results

Verified factory-test and acceptance information for this packaging line.

Quality Inspection

Recommended batch checks cover recipe and filling settings, fill weight, foam, dripping, leakage, cap condition, label accuracy, batch code, cleaning records, and changeover release. Food-safety and allergen controls remain within the producer’s validated plan.

Project Result Summary

The proposed machine delivers repeatable semi-automatic filling for the two sauces in this project while keeping bottle, cap, and label handling manual.

Final output, settings, and cleaning procedures must be confirmed with actual product and package samples.

How the Packaging Line Works

The connected production sequence from container infeed to finished product.

Batch and Machine Check

Confirm the selected sauce recipe, clean status, filling settings, bottles, caps, labels and batch code before production.

Sauce Bottle Staging

Place clean empty 500 mL bottles at the operator station.

Semi-Automatic Sauce Filling

Position each bottle under the nozzle and press the foot pedal; for foaming sauce, gradually lower the bottle during filling to reduce impact and foam.

Manual Cap Application

Place and tighten the specified sauce-bottle cap.

Manual Labeling and Coding

Apply the correct sauce label and batch identification.

Finished-Bottle Inspection

Check fill volume, foam level, leakage, cap condition, label and traceability.

Batch End and Sauce Recovery

Drain or recover the remaining sauce according to the approved batch procedure.

Cleaning and Next-Recipe Release

Clean and inspect the product-contact path before switching between soy sauce and barbecue sauce.

Key Engineering Features

Project-specific functions that improve stability, accuracy, safety and ease of operation.

Two-Head Sauce Filling

Supports small-batch filling for the two sauce types in this project.

Foot-Pedal Operation

Lets the operator start each fill cycle while positioning the bottle.

5–5,000 mL Filling Range

The published range covers the 500 mL bottle used in this project.

Manual Foam Control

Allows the operator to lower the bottle during filling to reduce splashing and foam.

Sauce Sample Testing

Confirms viscosity, foam behavior, temperature, particle-free condition, nozzle cut-off, material compatibility, and cleaning settings.

Manual Sauce Changeover

Uses sauce-specific cleaning, inspection, and setting resets between recipes.

Delivered Equipment and Line Scope

The supplied equipment and integration boundary for this project.

Proposed compact setup: bottle staging, LEKA-FLsemi-CLB02 filling, manual cap application, separate labeling and coding, finished-bottle inspection, and changeover cleaning tools.

Operation, Changeover and Site Requirements

Information used to plan cleaning, package changeover, utilities and installation.

Materials, Cleaning and Safety

Product-contact materials must be suitable for food use and compatible with both sauces and the selected cleaning chemicals. This setup is for smooth, particle-free products. Sauces with seeds, herbs, garlic pieces, or other solids—and very thick or hot-filled products—require separate sample testing and may need a different pump or nozzle system.

Changeover and Optional Equipment

Recipe changeover can include flushing or disassembly, hose and nozzle inspection, filling-setting reset, and cap and label checks. Dedicated product-contact parts may be required when the approved cleaning method cannot control flavor or allergen carryover.

Electrical Supply
Published reference: 0.8 kW and 220 V 50 Hz; confirm destination supply.
Compressed Air
Published reference: 0.4–0.6 MPa where pneumatic parts are used; confirm final configuration.
Sauce Feed
Confirm a clean feed vessel, suitable hose length and stable suction conditions for each approved sauce.
Cleaning Utilities
Confirm water, detergent, sanitizer, drainage and drying or inspection methods for sauce residue removal.
Operator Area
Provide safe bottle staging, foot-pedal operation, cap handling, label control and finished-bottle inspection space.

Delivery and Technical Support

Support available for installation, commissioning, training and continued operation.

Available support can include sauce-sample review, bottle and cap review, sample filling trials, filling-setting guidance, cleaning-planning support, operating documents, remote commissioning guidance and remote training.
