Glass bottling machine is a special machine for automatically filling liquid or semi-liquid products into glass bottles, plastic bottles and other containers. It is a subcategory of liquid filling machines, widely used in food, beverage, pharmaceutical, daily chemical and other industries, has achieved efficient and accurate bottling production. Here's a breakdown of the bottlers:
I. Core Functions
Automatic Filling
Precisely pour a predetermined amount of liquid (such as water, beverage, alcohol or liquid medicine) or half a liquid (such as soy sauce, shampoo or lubricants) into the bottle.
Container Compatibility
Available in a range of materials (glass, plastic, PET, etc.), shapes (round, square or special) and sizes (capacity and caliber).
Production Integration
Can be combined with bottling machine, sealing machine, labeling machine, case packers and other equipment to form a complete bottling production line.
ii. Operating Principles and Procedures
Bottle Conveyor
Empty bottles enter the filling machine via conveyor belts or star wheel (rotating equipment) and are secured by positioning devices (such as bottle stops or clamps). Filling prep
Negative Pressure Vacuuming (optional): Vacuum the bottle to reduce oxidation and fizz (e.g. filling of wine and beer).
Pre-Gas Filling (Optional): Inert gases (e.g. CO2, nitrogen) are added to the bottle to protect the product (e.g., carbonated beverages, juice).
Liquid Filling
Filling method options:
Atmospheric Pressure Filling: Liquid flows into a bottle under gravity. Suitable for low-viscosity, bubble-free liquids (such as mineral water, white wine).
Negative Pressure Filling: Liquid is vacuumed into the bottle to reduce foam (e.g., soy sauce, cooking oil).
Pressure Filling: Liquid is forced into a bottle by pump or air pressure. Suitable for high-viscosity or particulate-containing liquids (e.g., ketchup, shampoo).
Isobaric Filling: Fill the bottle with air to balance pressure before filling it with carbonated liquids (such as beer and soda) to prevent foam.
Quantitative Control:
Flowmeter: Liquid volume monitored by sensors with accuracy + -± 0.5%. Weigh: The change in bottle weight is detected using a weighing sensor, providing a higher accuracy (±0.1%).
Piston/Piston: Mechanical piston extracts a certain quantity of liquid for low or high precision filling (e.g. drugs and eye drops).
Completed filling: The filling head closes the valve and then removes the bottle via conveyor belt for subsequent treatment (e.g. sealing and labelling).
III. Key Technologies and Components:
Filling head: Material: Stainless steel, ceramic, or food-grade plastic, corrosion resistant, easy to clean.
Design: anti-drip structure (e.g., suck-back function), height adjustment to suit different bottle shapes.
Feeding system: includes liquid storage tank, pumps (such as gear pump, squirming pumps), pipes and filters to ensure a stable liquid supply and remove impurities.
Control System: Programmable Logic Controller (PLC) or industrial computer control process, while human-machine (Human Machine Interface HMI) sets parameters (such as filling volume, speed).
Detection and Protection: Liquid Level Sensor: Detects if the bottle is full or leaking.
Bottle test: prevents the filling head from drying out without the bottle. Safety light curtain: prevents operators from accidentally entering hazardous areas.
IV. INTRODUCTION Main Typess
Linear Bottle Filling Machine
Structure: The bottle is transported in a straight line with the filling head arranged vertically or at an angle.
Features: Low cost, high flexibility, suitable for small batch or high variety production (such as craft breweries and laboratories).
Rotating bottler
Structure: The bottle is mounted on a rotating table, and the filling head surrounds a central shaft.
Features: Extremely fast (thousands of bottles per hour), suitable for mass production (e.g. beverages and pharmaceutical plants).
Aseptic Bottle Filling Machine
Purpose: Filling sterile products that require long-term storage (such as UHT milk, juice and liquid medicine).
Process: Filling and sealing in a sterile environment in combination with steam sterilization sterilization, hydrogen peroxide fumigation or ultraviolet sterilization.
Vacuum Bottle Filling Machine
How it works: Vacuum pumps expel air from the bottle and then inhale the liquid, reducing oxidation and foaming. Suitable for: oxidizing liquids (e.g. wine, cooking oil) or high foam liquids (e.g. beer, detergent).
V. Application Scenarios
Food industry: Mineral water, juice, alcohol, condiments, cooking oil, etc.
Pharmaceutical industry: oral fluids, injections, eye drops, disinfectant, etc..
Daily chemicals: shampoo, shower gel, skin care products, detergent and so on.
Chemical industry: lubricants, paints, glue, pesticides, etc.
6. Strengths and trends
Strengths:
Increased productivity (more than 10 times faster than manual filling).
Ensure consistency of filling (error rate as low as ± ± 0.1%).
Reduce labor costs and product losses.
Adhere to hygiene standards (such as GMP and FDA) to reduce contamination risks.
Trends:
Intelligent: Combining AI vision detection with the Internet of Things (IoT) for remote monitoring and fault prediction.
Flexibility: Modular design that allows quick switching between bottle types and filling specification.
Environmentally Friendly: Energy-saving motors and low noise design, reduce energy consumption and noise pollution.
