750ML Glass Bottle Olive Oil Piston Filling ROPP Capping Machine

Q1  What filling method do you use for edible oil and condiments — weighing (gravimetric), flow meter, or piston filling?

For edible oil and condiments, the optimal filling methods are:

-Flow meter filling(preferred for edible oil due to high speed, accuracy, and temperature compensation).

- Piston filling(ideal for viscous condiments like sauces, ketchup, or dressings with particulates).

- Weighing (gravimetric) for high-precision or legal-for-trade applications, but slower and costlier.

Q2  Can the same machine fill both thin liquids (soy sauce, vinegar) and thick/viscous products (ketchup, chili sauce)?

Thin liquids like soy sauce,vinegar normally use vacuum filling machine or flow meter filling machine, while thick/viscous product like ketchup, chili sauce normally use piston filling machine. So different product have its own most suitable filling machine.

Q3  What bottle sizes and materials are supported — 500ml glass bottle, 5L PET bottle, or flexible pouch?

Condiments filling machine can work with different bottle material including glass bottle and PET bottle in one machine, but normally use separate machine if the cap/closures are different. Flexible pouch filling machine is different one with glass bottle or plastic bottle filling machine.

Q4  What is the filling accuracy for your oil filling machine — how many grams deviation is allowed per bottle?

For our oil weighing filling machine, the filling accuracy is typically ±0.5–1 gram per bottle, depending on oil viscosity and bottle size. Deviation tolerance is generally ≤1 gram for standard applications.

Q5  What capping types does the machine support — ROPP aluminum cap, plastic screw cap, or pump dispenser cap?

Edible oil filling machine supports ROPP aluminum caps, plastic screw caps, and pump dispenser caps.

Q6  How do you prevent dripping or leaking between fills, which causes product waste and contamination?

To prevent dripping or leaking between fills and reduce waste/contamination:

Use anti-drip nozzles or spring-loaded check valves.

Implement positive shut-off valves (e.g., diaphragm or pinch valves).

Maintain proper seal and gasket integrity (replace worn parts).

Control pressure and viscosity with pump synchronization or suck-back function.

Install drip trays or sensors for early leak detection

Q7  Is the machine suitable for filling hot-filled condiments (e.g., tomato paste at 85 degrees Celsius)?

Yes, piston filling machine is suitable for hot-filled condiments like tomato paste at 85°C, provided it is equipped with heat-resistant seals and a temperature-tolerant filling system. Suitable for hot fill, high-viscosity, and aseptic applications.

Q8  What is the production speed (bottles per minute or per hour) for a typical 1L edible oil bottle?

For a typical 1L edible oil bottle filling machine, the production speed ranges from 1,000 to 18,000 bottles per hour (BPH) for standard automatic lines.

Q9  Can the filling machine handle products with solids or chunks, such as chili oil with pepper flakes?

Yes, many filling machines can handle products with solids or chunks like chili oil with pepper flakes, provided they are equipped with specific features such as wide nozzles, rotary or piston fillers, and agitation systems to prevent settling. For accurate selection, check the machine’s compatibility with particulate size and viscosity.

Q10  What is the minimum investment for a semi-automatic condiments filling line vs. a fully automatic line?

For a semi-automatic condiments filling line, the minimum investment is typically $10,000–$20,000.  

For a fully automatic line, the minimum starts around $30,000–$`50,000 and up.
