Paste Filling Machine is an industrial dosing solution engineered for viscous, semi-solid, and non-flowing substances. Utilizing volumetric piston dosing and rotary valve control, the equipment handles complex rheological fluids without dripping or stringing. The sanitary structural design enables rapid disassembly for batch changeovers and hygienic processing.

Dosing & Flow Control Architecture
Piston Volumetric Metering: Precision-honed stroke cylinders deliver exact volume control regardless of temperature shifts or ambient pressure changes.
Positive Cut-Off Nozzles: Bottom-up filling combined with pneumatic shut-off nozzles eliminates stringing and rim contamination on containers.
Servo Stroke Adjustment: Multi-axis servo drives enable instant volume modifications and velocity tuning for shear-sensitive formulations.
Viscosity & Material Compatibility
Personal Care Products
Cream, lotion, gel, mascara, hair wax, and toothpaste.
Food Products
Peanut butter, jam, fruit preserves, tomato paste, honey, mustard, and sauce.
Industrial Media
Grease, silicone sealant, paste wax, adhesive, and putty.
Pharmaceutical Formulations
Ointment, salve, medical gel, and viscous botanical extract.
Machine Configurations
Automatic In-Line Systems
Conveyor indexing units with multi-head nozzles for continuous packaging operations.
Semi-Automatic Standalone Units
Foot-pedal or proximity-sensor activated single or double-head desktop systems suitable for smaller production batches.
Thermal & Agitation Modules
Jacketed hoppers with electric heating elements and scraper agitators keep hot-fill materials fluid during processing.
Cleanability & Sanitary Standards
Tool-Free Tri-Clamp Assembly: Product contact paths connect via quick-release sanitary tri-clamp fittings, eliminating internal threads and dead legs.
Clean-In-Place Readiness: Internal flow channels withstand caustic rinses and steam cycle temperatures without seal breakdown.
Quick-Changeover Mechanics: Standardized guide rails and digital recipe selection shorten product changeover times.
Quality Control & Testing
Material Traceability
Stainless steel components supply mill test verification for 316L and 304 chemical composition.
Pre-Shipment Endurance Testing
Every unit completes continuous dynamic testing using target viscosity media prior to factory release.
Dimensional Inspection
Machined parts pass coordinate measuring checks to verify dynamic seal fits and piston tolerances.
Container Handling
Multi-Format Container Compatibility
Processes rigid glass jars, plastic bottles, squeezable tubes, aluminum cans, and buckets.
Line Integration Capabilities
Connects with container unscramblers, rotary capping machinery, induction sealers, and labeling units.
Container Detection System
Optical sensors verify container positioning before nozzle actuation, preventing material discharge onto empty spaces.
Customization & Project Options
Sample Fluid Analysis
Raw product samples undergo viscosity mapping and nozzle sizing prior to manufacturing.
Hopper Modifications
Custom hopper geometries, pneumatic pushers, and augmented heating jackets adapt to precise production footprints.
Documentation Package
Includes operation manuals, electrical schematics, spare parts lists, and factory test protocols.
FAQ
Q: How does the machine handle products containing small solid particles?
A: Rotary valve configurations with enlarged passages permit soft particles and seeds to pass through without clogging or damaging the product matrix.
Q: What mechanism prevents stringing when dispensing sticky media?
A: A combination of pneumatic shut-off tips and an adjustable suck-back stroke retracts fluid into the nozzle tip at stroke completion.
Q: Can filling volumes be modified quickly between batches?
A: Servo-driven models adjust stroke lengths through touchscreen memory recipes, while pneumatic models utilize a calibrated handwheel with digital display.
Q: What temperature control options exist for heat-sensitive pastes?
A: Hoppers can feature water-jacketed or oil-jacketed heating channels monitored by digital PID controllers up to 90°C.
Q: Are fluid contact seals certified for regulatory compliance?
A: Contact seals utilize food-grade PTFE, Viton, or silicone materials rated for direct contact with consumable and personal care items.
