Product Introduction
Complete System:
Z-type bucket elevator + 10-head combination weigher + vertical form-fill-seal (VFFS) packaging machine + finished product discharge conveyor. This integrated granule packaging line is widely used for granular products such as nuts, puffed snacks, candies, seeds, freeze-dried foods, and pet food.
| Comparison Item | Multi‑head Combination Weigher | Volumetric Cup Filler |
| Working Principle | Gravimetric weighing: multiple independent weighing hoppers + CPU combination algorithm, select best weight combination | Volumetric measuring: fixed‑volume cups discharge material by volume, no real‑time weight detection |
| Typical Accuracy | ±0.3g‑±5g (depends on target weight and material) | ±10g‑±30g, affected by bulk density, particle size difference |
| Running Speed | 30‑70 cycles/min for standard 10‑head model | 15‑30 bags/min |
| Material Adaptability | Granules, blocks, slices, irregular‑shape snacks, nuts, pet food, frozen food. Tolerate uneven particle size | Only for free‑flowing uniform granules. Poor performance for uneven, oily or sticky products |
| Material Waste | Low giveaway, reduces loss of high‑value products | High overfill loss, density fluctuation causes weight deviation |
| Operation & Adjustment | Set target weight on touch screen, store product recipes | Need to change or adjust cup height for different filling volume |
| Equipment Cost | Higher initial investment | Low cost, economical solution |
| Maintenance | Regular cleaning for hoppers; protect load‑cells from heavy vibration | Simple mechanical structure, easy maintenance |
| Comparison Item | Collar Former | Triangle‑plate Former |
| Structure Feature | Collar‑shaped polished curved surface with central feeding tube, integrated stainless steel assembly | Triangular inclined plate plus guide rollers, simple construction |
| Bag‑width Change | One set for one bag width. The whole former must be replaced for different bag sizes | No spare‑part replacement required. Adjust position to fit various bag widths |
| Compatible Film | Thick composite film, aluminum‑foil film, metallized film, large‑bag film; not fit for ultra‑thin single‑layer film | Thin PE film & ordinary thin composite film; heavy wrinkles occur with thick aluminum‑foil film |
| Bag Appearance | Square and rigid bags with neat sealing edge, excellent retail look | Soft bag shape; wrinkles & twisting easily happen on large bags |
| Applicable Bag Size | Medium‑large bag: 100g‑5kg (nuts, pet food, grains) | Small‑medium sachet: 5‑200g (spices, mini snacks) |
| Adjustment Difficulty | High‑precision adjustment required; slight misalignment causes twisted bags | Easy setting, friendly for new operators |
| Cost | Higher mould cost | Low cost |
| Film Bending Resistance | Large forming resistance; thin film may be stretched | Low resistance, smooth film running |
