As a professional filling machine supplier, we’ve structured the key classification methods of filling machines to help enterprises select the right equipment based on production scenarios, material characteristics, and automation needs:
1. By Filling Principle
Atmospheric Pressure Filling Machine: Fills liquids under normal pressure, suitable for low-viscosity, gas-free products (e.g., purified water, edible oil, daily chemical toner) with simple structure and low cost.
Pressure Filling Machine: Uses mechanical pressure to transfer materials, designed for high-viscosity substances (e.g., tomato sauce, toothpaste, ointment, balm) to avoid clogging.
Vacuum Filling Machine: Evacuates containers first before filling, ideal for low-viscosity liquids (e.g., syrup, pesticides, chemical reagents, vitamin drinks) to reduce oxidation.
Isobaric Filling Machine: Balances pressure between container and liquid tank before filling, suitable for carbonated products (e.g., beer, soda, sparkling water) to retain CO₂.
2. By Material Form
Liquid Filling Machine: Adapts to various liquids (from low-viscosity water to high-viscosity essential oil), widely used in daily chemical, food, pharmaceutical, and oil industries.
Paste Filling Machine: For cream, gel-like materials (e.g., facial cream, hand cream, minced meat, broad bean paste), ensuring sealed filling and quantitative accuracy.
Aerosol Filling Machine: Special pressure equipment with propellant filling (e.g., spray paint, insecticide, setting spray), process: liquid filling → sealing → gas filling.
Powder Filling Machine: Fills powder and small granular materials (e.g., milk powder, washing powder, pesticide powder, condiments) with dust-proof design for chemical and food industries.
Granule Filling Machine: Suitable for granular materials (e.g., coffee powder, seeds, sugar, granular medicine), supporting small-bag packaging or bulk filling.
3. By Container Movement
Rotary Filling Machine: Containers rotate with the turntable, continuously completing filling → capping, high efficiency (ideal for mass production in food and beverage industries).
Linear Filling Machine: Containers move linearly, filling in rows intermittently, simple structure and easy maintenance but limited capacity, suitable for small-batch gas-free liquid filling.
4. By Automation Level
Manual Filling: Fully manual operation, no equipment dependency, only for small-batch, gas-free liquids (e.g., laboratory samples, small handmade workshops).
Semi-Automatic Filling Machine: Automatic filling with manual bottle loading/unloading, balancing cost and efficiency, suitable for trial production or small-batch production in SMEs.
Automatic Filling Machine: Includes single-machine automation and production line integration, supporting fully automated processes (filling → sealing → labeling → inspection) for large-scale production in medium and large enterprises.
