We are a professional porridge production line equipment manufacturer, offering complete automated solutions from raw material processing to finished product packaging.
This production line utilizes innovative technology where soybeans require no soaking—directly dehulled and ground into slurry, eliminating the beany odor, bitterness, and protein loss associated with traditional soaking methods.
Featuring high-speed, ultra-precision wet ultrafine multi-stage grinding, it replaces conventional residue-removal processes, achieving micron-level soybean refinement to fully retain plant protein and dietary fiber. Combined with a proprietary multi-stage swelling technique, it maximizes nutritional preservation while reducing costs, delivering a final product with rich aroma and silky texture—an ideal health-conscious meal replacement.
With clear market differentiation and easy promotion, this product serves not only as ready-to-eat porridge but also as a premium base material for plant-based beverages, empowering businesses to tap into the healthy drink industry.
Combining precision engineering with strict hygiene standards
Raw Material Prep:

Container Cleaning:
Air-knife dust removal + ionized air sterilization
Nitrogen Flushing (O₂ ≤ 0.5%) →
Volumetric servo-filling (±0.5% accuracy)
→ Laser seam sealing
Vision Inspection:
Leak detection/weight verification
Secondary Packaging:
packing & palletizing
Comparison Dimension | Longying Smart Filling Line | Traditional Filling Line | Longying Core Advantage |
Automation Level | Full-process automation (feeding→filling→sealing→inspection→case packing→palletizing) | Semi-automated, manual intervention required (alignment/labeling/handling) | 90% less human intervention, eliminates human errors |
Filling Accuracy | ±0.3% servo closed-loop control (gravimetric/flowmeter feedback) | ±1.5%~2% mechanical timed filling | Saves >¥500k/year in material loss (at 100k bottles/day) |
Production Speed | 12,500 bottles/hour (24/7 operation) | ≤3,500 bottles/hour (declining efficiency with labor) | 275% higher output, 60% shorter lead times |
Production Flexibility | 15-min quick changeover (bottles/boxes/pouches/cans; handles soy milk, juice, detergent, etc.) | 4~8 hours line change (mold replacement + mechanical adjustment) | Supports high-mix, low-volume customization |
Aseptic Guarantee | Triple protection: CIP + SIP sterilization + Class A laminar flow | Manual cleaning + alcohol spray | ≤0.1 CFU/mL microbial control (medical-grade standard) |
Nitrogen Flushing | Integrated auto-flushing (residual O₂ ≤0.5%, extends shelf life 30%) | Manual external equipment (residual O₂ ≥3%) | Meets preservation needs for premium beverages (e.g., plant protein) |
Quality Control | AI vision inspection (fill level/seal/label) + inline checkweigher rejection | Manual sampling (≥5% defect escape rate) | ≤0.01% defect rate vs. 2%~5% on traditional lines |
