Viscosity, a measure of a liquid’s resistance to flow, dictates how easily a product moves through packaging equipment. Expressed in centipoise (cps), water has a viscosity of 1 cps, while ketchup ranges from 50,000–70,000 cps. High-viscosity liquids like honey (10,000 cps) require more force to dispense, impacting filler selection.
Why It Matters: Viscosity affects flow rates and fill accuracy. HIJPACK Machine’s automatic liquid pouch packing machines use piston pumps for high-viscosity products (up to 100,000 cps), delivering ±0.5ml precision, while low-viscosity liquids like water use gravity fillers. Accurate viscosity data ensures fillers provide optimal force without overfilling, reducing waste by 10%.
Tip: Test your product’s viscosity at operating conditions and share results with your equipment provider to ensure compatibility.
Temperature influences viscosity, altering how liquids flow during packaging. Heating reduces viscosity—molasses at 20°C (10,000 cps) becomes free-flowing at 50°C—due to increased molecular movement and lower surface tension.
Why It Matters: Fill temperature determines filler and pump configurations. HIJPACK Machine’s automatic packing machines support hot-fill (up to 85°C) and cold-fill (5–20°C) applications, with insulated hoppers for hot liquids like soups and cooling systems for beverages. Incorrect temperature specs can lead to overfills or equipment strain, increasing downtime by 15%.
Tip: Specify exact fill temperatures (e.g., 80°C for hot sauce) to ensure equipment handles your product’s flow characteristics effectively.
Liquids like salad dressings or broths often contain particulates—spices, vegetables, or herbs—that vary in size (0.5–5mm) and behavior (suspended or settling). These affect dispensing accuracy and equipment durability.
Why It Matters: Particulate size and properties guide filler selection. HIJPACK Machine’s automatic liquid pouch packing machines use servo-driven piston fillers with wide nozzles for particulates up to 5mm, ensuring ±1ml accuracy for chunky sauces. Anti-clog systems prevent blockages, maintaining 99.9% uptime.
Tip: Measure average particulate size and note settling behavior to select fillers that avoid clogging and ensure uniform fills.
HIJPACK Machine’s automatic packing machines are engineered for precision and versatility:
The HIJ8-200R supports piston, gravity, and peristaltic pumps, handling viscosities from 1–100,000 cps. Servo controls achieve ±0.5ml accuracy, while 10-inch touchscreen PLCs allow real-time adjustments, reducing setup time by 20%.
Machines support pouches from 10ml to 2,500ml, including stand-up pouches, spouted pouches, and sachets. Nitrogen flushing extends shelf life by 25%, ideal for juices and sauces.
