How does the single-lane liquid packaging machine handle different viscosities?

ZSYAN SY-L180/SY-L240 uses a piston metering system that can handle liquids from 1–1000 cP viscosity, including edible oils (low viscosity), chili paste and honey (medium viscosity), and peanut butter and creams (high viscosity). Switching between products only requires selecting the corresponding recipe — the machine automatically adjusts piston stroke and packaging speed.

How long does it take to switch from chili paste to honey?

Using the 99-recipe one-touch switching function, switching from chili paste to honey takes about 2–3 minutes: select the recipe → machine auto-adjusts parameters → verify 5 bags → confirm and start production. Compared with 30 minutes of manual cleaning and calibration, this saves over 90% of time.

What is the metering accuracy of the single-lane liquid packaging machine?

The piston metering system achieves ±1% accuracy. For a 500g bag, the actual weight is controlled within 495–505g. High precision comes from precise piston stroke control and inner wall polishing to reduce liquid residue.

How does the liquid packaging machine prevent cross-contamination?

ZSYAN liquid packaging machines feature three hygienic designs: (1) detachable metering cylinder and feeding pipes for thorough cleaning; (2) inner walls polished to Ra≤0.4μm to reduce liquid residue; (3) piston retraction creates negative pressure to suck back residual liquid. Cross-contamination rate is below 0.05%.

How to choose between SY-L180 and SY-L240?

The choice depends on bag weight range and capacity needs: SY-L180 suits 1–500g bags at 20–35 bags/min, ideal for small-to-medium production lines; SY-L240 suits 1–1000g bags at 35–50 bags/min, ideal for large-scale production lines. If you mainly package small bags under 500g, SY-L180 offers better cost-performance.

High-Speed Packaging Machine Setup, Operation, and Maintenance: Complete Operator Guide

Setting up the ZSYAN SY-L180 high-speed packaging machine takes approximately 45 minutes for the first installation and 15 minutes for subsequent product changeovers. Daily operation requires a 10-minute startup checklist, continuous monitoring of bag weight and seal quality, and a 15-minute end-of-shift cleaning routine. Weekly maintenance takes 30 minutes and includes lubrication, belt inspection, and cup cleaning. Monthly calibration ensures plus or minus 1 gram filling accuracy is maintained. Proper maintenance extends machine lifespan to 10 to 15 years with minimal downtime.

I. Pre-Installation Checklist

Before uncrating the SY-L180, verify these prerequisites: electrical supply of single-phase AC 220V at 50Hz or 60Hz with dedicated 15-amp circuit, compressed air supply at 6 to 8 bar pressure if using a pneumatic date coder, flooring capacity of at least 500 kg per square meter to support the 450kg machine weight, ambient temperature between 10 and 40 degrees Celsius, and relative humidity below 80 percent to prevent electrical component corrosion.

Position the machine with at least 800mm clearance on all sides for operator access and maintenance. Install a 1,500mm output conveyor if packaging into cartons or bags. Connect the date coder cable to the PLC terminal if using inkjet coding.

II. Film Loading and Forming Collar Setup

Mount the film roll onto the unwinder arbor, ensuring the film unwinds from the bottom to minimize tension variations. Thread the film through the tension-control rollers in the sequence shown on the roller diagram sticker located on the machine frame.

Insert the forming collar into the film path. The forming collar shape determines the bag style: cylindrical collars produce back-seal pillow sachets, while shaped collars produce three-side seal stand-up pouches. Secure the collar with the four locking knobs and verify it is centered in the film path.

Thread the film through the vertical sealing jaw assembly and into the horizontal sealing and cutting mechanism. Pull approximately 500mm of film through the entire path and cut the leading edge at a 45-degree angle to facilitate smooth feeding into the forming collar.

III. First Run: Calibrating Fill Weight and Bag Length

Power on the machine and wait for the PLC to complete its initialization sequence, which takes approximately 30 seconds. The 7-inch touch screen will display the home menu. Select New Program and enter the target bag length and fill weight.

Run the machine empty for 5 minutes to verify film tracking, seal quality, and cutting accuracy. Check that the vertical seal is straight and continuous, the horizontal seals are uniform across the bag width, and the cutting blade produces clean edges without fraying.

Load product into the hopper and run 20 test bags. Weigh each bag on a calibrated scale and record the results. Adjust the cup fill volume through the touch screen until all 20 bags fall within plus or minus 1g of the target weight. Record the final cup setting in the program for future reference.

IV. Daily Operation Checklist

Start-of-shift checklist: verify compressed air pressure if using a date coder, confirm film roll has sufficient length, check product hopper level, inspect seal jaws for debris or wear, power on and run a 2-minute warm-up cycle, and take 5 sample bags for weight and seal verification.

During operation: monitor the touch screen for fault alerts, check bag seal quality every 30 minutes by performing a peel test, verify fill weight accuracy every hour with a calibrated scale, and watch for unusual vibrations or noise from the servo motor.

End-of-shift checklist: run an empty cycle to clear residual product from the hopper and cup drum, wipe all product-contact surfaces with food-safe cleaner, inspect seal jaws and cover with protective film, power down the machine, and record production output and any anomalies in the shift log.

V. Weekly and Monthly Maintenance

Weekly maintenance takes 30 minutes: lubricate all servo motor guide rails and bearing points with food-grade lubricant, inspect and adjust belt tension on the output conveyor, clean the measuring cup drum interior to remove product buildup, check the date coder ink level and print head condition, and inspect all electrical connections for tightness.

Monthly maintenance takes 2 hours: calibrate the fill weight system using certified test weights, inspect seal jaw temperature probes and replace if calibration drift exceeds plus or minus 5 degrees Celsius, check the forming collar for wear marks that could damage film, inspect the servo motor coupling for wear, and back up all stored programs to USB storage.

Annual maintenance: full service inspection by a certified technician, servo motor bearing inspection and replacement if needed, PLC battery replacement, complete disassembly and deep cleaning of all product-contact components, and comprehensive safety system verification including all interlocks and emergency stops.
