Client Profile
Industry: Food & Beverage / Health Supplement Manufacturer
Location: Estonia
Packaging Type: 4-Side / 3-Side Seal Sachet (50mm width)
Target Volume: 15g per sachet
Production Speed: 30 sachets/min
The Challenge: Viscosity, Temperature, and Stringing Issues
Packaging high-viscosity liquid syrup into small 15g sachets presents severe technical hurdles on standard pouch packaging equipment:
High Viscosity & Inaccurate Metering: Dense syrup flows poorly, leading to inconsistent weight tolerance during high-speed filling.
Temperature Sensitivity & Crystallization: Ambient temperature changes directly alter syrup fluidity. Cooling syrup causes sugar crystals to precipitate, clogging piston pumps and seizing mechanical components.
Nozzle Dripping & Stringing: Strong syrup molecular adhesion causes persistent tailing and liquid dripping at the nozzle, contaminating sachet sealing zones and causing pouch leaks.
To solve these pain points, Vican Packing engineered a specialized viscous liquid filling packaging machine with constant temperature control and precision servo dosing.
The Solution: Servo-Driven Constant Temperature Sachet Packaging Line
Our customized automatic bag filling and sealing machine integrates dynamic temperature management and intelligent anti-drip mechanisms:
1. Servo-Driven Piston Metering with Dynamic Back-Suction
The servo plunger synchronizes directly with a reverse back-suction valve at the moment of discharge, instantly drawing back residual syrup from the needle. Millisecond-level adjustable stroke force completely eliminates tailing and dripping.
3. Integrated Jacketed Constant Temperature Water Circulation
The pump chamber, plunger, and inlet/outlet valves are continuously heated at a steady 32°C–38°C. This maintains optimal syrup fluidity and prevents sugar crystallization jams.
3. Automatic Bi-Directional CIP Flushing
During CIP cycles, the servo motor drives the plunger back and forth to flush out residual sugar deposits in pump dead-corners automatically without machine disassembly, saving changeover time and avoiding cross-contamination.
4. Closed-Loop Weight Compensation Touchscreen System
Operators enter target weight directly on the HMI. Integrated checkweighing feeds weight data back into the servo system for instant micro-adjustments, ensuring long-term weight accuracy without manual calibration.
5. 3-Line Ribbon Date Coding Printer
Stamps production date, expiration date, and batch number (MFG, EXP, LOT) clearly onto each sachet.
Client Review & Testimonial
"Switching to Vican Packing’s servo piston VFFS machine with integrated CIP cleaning transformed our sachet line. The 15g filling weight remains rock-solid, and dripping defects at the sealing area have been completely eliminated at 30 sachets per minute. Built-in automatic cleaning saves us hours during product changeovers and stopped syrup crystallization entirely. It has drastically reduced both material loss and labor overhead!"
