A paste filling machine is an automated device specifically designed for filling high-viscosity liquids or semi-solid materials. It is widely used in the food, cosmetics, chemical, and daily chemical industries for products such as honey, jam, chocolate paste, creams, lotions, and adhesives.

Working Principle

Paste filling machines typically use piston pumps, rotor pumps, or gear pumps, which apply mechanical pressure to accurately inject high-viscosity materials into containers. Compared to ordinary liquid filling machines, they can handle thick, slow-flowing materials, ensuring uniform filling without dripping. Some models also support multi-head filling for higher production efficiency.

Key Functions and Advantages

1. High-Precision Filling
   Each filling volume can be adjusted to ensure consistent product specifications and minimize waste.
2. Suitable for Various Viscosities
   Stable filling is possible for both thick sauces and semi-solid pastes.
3. Improved Production Efficiency
   Automated operation saves labor and supports continuous production, greatly increasing output.
4. Easy Operation and Cleaning
   Compact structure, easy to disassemble, ideal for frequent material changes and cleaning.
5. Reduced Production Costs
   Precise filling control reduces material waste and labor costs.

Applications and Industries

• Food Industry: sauces, jams, honey, chocolate paste, condiments
• Cosmetics Industry: creams, lotions, shampoos, skincare pastes
• Chemical Industry: adhesives, lubricants, colloidal products
• Others: medicinal pastes, specialty viscous liquids

Choosing a Paste Filling Machine

When selecting a paste filling machine, consider material viscosity, production volume, container type, and automation level. Advanced models may feature touch-screen control, automatic calibration, and multi-head synchronous filling to meet diverse production requirements.

ZONESUN paste filling machines deliver high-precision and efficient solutions for filling a wide range of materials, from low-viscosity liquids to high-viscosity creams, gels, and sauces. Featuring gear, piston, servo, and rotary pumps, our viscous filling equipment ensures accurate dosing, consistent output, and easy cleaning, making it ideal for food, cosmetics, pharmaceutical, and chemical industries.
