Product Overview
Congee is an instant convenient food industrially processed from grains (e.g., japonica rice, glutinous rice, black rice), legumes (e.g., mung beans, red beans), nuts (e.g., peanuts, lotus seeds), and nutritional additives (e.g., barley, longan).
Core Advantages:
Complete Nutrition: Rich in protein, dietary fiber, vitamins, and minerals.
Innovative Process: Raw material filling + high-pressure sterilization & cooking technology, preservative-free.
Convenience: Shelf-stable for up to 1 year at room temperature, suitable for both hot and cold consumption, ready-to-eat.
Product Classification
| Classification Criteria | Specific Types |
| Packaging Form | Disposable cup packaging, bowl packaging (eco-friendly biodegradable materials optional) |
| Shelf Life | 6 months or 1 year at room temperature (determined by sterilization process) |
| Filling Process | Raw Material Filling (Shanghai Longying’s core technology), Cooked Material Filling (traditional process) |
Raw Material Filling vs. Cooked Material Filling Process Comparison
| Item | Raw Material Filling Process | Traditional Cooked Material Filling Process |
| Process Flow | Raw grains + additives → Filling → Sealing → Rotary high-temperature sterilization & cooking | Pre-cooking → Cooling → Filling → Secondary sterilization |
| Advantages | 1. Oxidation-resistant, retains flavor and nutrients; 2. Saves pre-cooking energy and labor costs; 3. Bright product color |
Simple process, lower equipment cost |
| Applicable Products | Long-shelf-life congee (e.g., eight-treasure congee, mung bean congee) | Short-shelf-life congee |
Core Equipment for Eight-Treasure Congee Production Line
| Equipment Module | Function Description |
