On Feb. 27th of  2026, we successfully delivered a complete 750ml glass bottle alcohol filling line to a valued customer in Vietnam.

The production capacity is 1000 bottles per hour (1000BPH), specially designed for high-proof liquor filling with aluminum caps, meeting strict safety and stability requirements.

This project includes:

• Glass bottle unscrambler

• Alcohol filling machine

• Explosion-proof motor system

• Light inspection machine

• Air drying machine

• Double-side labeling machine

• Semi-automatic carton packing machine

This turnkey solution ensures stable operation, safe alcohol filling, and high-quality packaging output.

Project Overview – 750ml Alcohol Filling Line (1000BPH)

Product: Liquor / Alcohol
Bottle Type: 750ml Glass Bottle
Cap Type: Aluminum Cap
Speed: 1000 BPH
Market: Vietnam

Unlike water or juice filling, alcohol filling requires higher safety standards, especially for flammable vapor control and electrical explosion protection.

From machine layout design to motor configuration, this line was engineered specifically for alcohol production environments.

1️⃣ Glass Bottle Unscrambler – Stable Feeding for Heavy Glass Bottles

For this Vietnam project, the customer selected a glass bottle unscrambler designed for:

• Heavy 750ml glass bottles

• Scratch-free bottle handling

• Stable bottle output alignment

• Smooth connection to filling machine

Industry Insight (20 Years Experience)

Many factories underestimate the importance of a glass bottle unscrambler.

For glass bottles:

• Bottle weight is heavier

• Bottle base friction is higher

• Impact resistance must be considered

If structure rigidity is insufficient, micro-collisions may occur — causing invisible cracks that later lead to breakage during capping.

We reinforced:

• Stainless steel frame thickness

• Soft contact guide rails

• Adjustable bottle guiding system

This ensures long-term stable performance.

2️⃣ 1000BPH Alcohol Filling Machine – Precision & Safety First

The core of this line is the 750ml alcohol filling machine, designed for:

• 1000 bottles per hour

• High-proof alcohol

• Glass bottle filling

• Aluminum cap sealing

Key Technical Features

✔ Anti-drip filling valves
✔ High precision volumetric control
✔ SUS304/316L contact parts
✔ Explosion-proof electrical system
✔ Vapor-safe design

Filling Valve Selection – Important Detail Most Buyers Ignore

For alcohol filling, choosing the correct filling valve is critical:

• Gravity filling is suitable for low-viscosity alcohol.

• If the product contains sugar or additives, a slight negative pressure system is recommended.

• High-proof alcohol requires better sealing design to prevent vapor leakage.

We optimized the valve sealing structure to reduce vapor escape — improving both safety and filling accuracy.

3️⃣ Explosion-Proof Motor System – Essential for Alcohol Production

This Vietnam project required explosion-proof motors due to flammable alcohol vapor.

Why This Is Critical

Alcohol vapor can form explosive mixtures in enclosed spaces.
If ordinary motors are used, sparks from internal electrical components can pose serious safety risks.

We equipped:

• Explosion-proof main motor

• Sealed electrical cabinet

• Grounding protection system

Industry Trend Insight

More Southeast Asian factories are upgrading to explosion-proof systems, especially for:

• High-proof liquor

• Disinfectant alcohol

• Industrial ethanol

Investing in explosion-proof equipment early avoids future compliance upgrade costs.

4️⃣ Light Inspection Machine – Quality Control Before Labeling

Before labeling and packing, each bottle passes through a light inspection machine.

It checks:

• Filling level consistency

• Foreign particles

• Glass defects

• Cap sealing condition

Why This Step Increases Brand Value

For premium liquor brands, visual consistency matters.
A ±2–3ml visible difference can affect consumer perception.

Even at 1000BPH, quality control should never be sacrificed for speed.

5️⃣ Air Drying Machine – Preparing Bottles for Perfect Labeling

After filling and capping, bottles go through a high-pressure air drying machine.

This ensures:

• No water drops

• No condensation

• Clean surface for labeling

Especially in Vietnam’s humid climate, proper drying significantly improves label adhesion quality.

6️⃣ Double-Side Labeling Machine – Accurate Alignment on Glass Bottles

The line includes a double-side labeling machine designed for:

• Front & back labels

• Transparent or opaque labels

• Glass bottle smooth surfaces

Technical Optimization

Glass bottles often have slight dimensional tolerances.

We used:

• Adjustable pressing belt system

• Servo-controlled label feeding

• Position fine-tuning mechanism

This ensures consistent alignment at 1000BPH.

7️⃣ Semi-Automatic Carton Packing Machine – Flexible & Cost-Effective

For final packaging, the customer selected a semi-automatic carton packing machine.

Why semi-auto?

At 1000BPH, full automatic case packers are optional but not mandatory.
Semi-automatic packing offers:

• Lower investment

• Flexible carton size adjustment

• Reduced maintenance complexity

For mid-speed alcohol production lines, this is often the most cost-efficient choice.

Complete Line Advantages for Vietnam Client

✔ Explosion-proof safety compliance
✔ Stable 1000BPH output
✔ Scratch-free glass handling
✔ High-precision alcohol filling
✔ Strong labeling consistency
✔ Flexible end packaging

This solution helps the client achieve:

• Lower labor cost

• Stable production

• Improved brand image

• Safer operation

Expert Advice: Choosing the Right Alcohol Filling Line

When selecting a 750ml alcohol filling line, consider:

1. Is explosion-proof configuration required?

2. What is the actual alcohol percentage?

3. Is future capacity expansion planned?

4. Is labeling precision important for branding?

5. What is the local humidity level?

Many buyers focus only on price and speed — but long-term stability and compliance determine true ROI.
