Concentrated Juice Processing Line
A concentrate line built around evaporation and aroma recovery, because concentrate without recovered aroma cannot be reconstituted into a product that tastes like juice.
Key Specifications
| Feed capacity | 1,000 - 15,000 L per hour |
|---|---|
| Output Brix | 60-72 degrees Brix |
| Evaporator | Falling film or forced circulation, 2-4 effect |
| Aroma recovery | Distillation column, 100-150 fold concentrate |
| Thermal treatment | 80-95 degrees C before evaporation |
| Storage | Aseptic bag-in-drum, 200 L or 1,000 L |
| Vitamin retention | ≥ 85 percent with low-temperature evaporation |
Aroma recovery is what makes concentrate usable
Evaporation strips volatile aroma compounds that give juice its fresh character. A distillation column captures these before evaporation and concentrates them 100-150 fold, so they can be dosed back during reconstitution.
Multiple effects cut energy use
A single-effect evaporator uses about 1 kg of steam per kg of water removed. A four-effect unit uses about 0.3 kg, which on a 10,000 L per hour feed is the difference between a viable and a marginal plant.
Aseptic drum filling for storage
Concentrate is stored at ambient for months. Aseptic bag-in-drum filling with a validated sterile path keeps it stable without refrigeration.
Typical Applications
- Fruit processing plants in season — Concentrate lets a plant buy fruit at harvest and sell juice year-round.
- Export of fruit solids — Concentrate removes most of the water, cutting freight cost dramatically compared with single-strength juice.
- Beverage premix manufacturing — Standardised 65 Brix concentrate is the input for reconstituted juice and drinks.
Frequently Asked Questions
Should I recover aroma?
Yes for any product sold as juice. Without aroma recovery, reconstituted juice tastes flat and buyers discount it.
How many effects do I need?
Two for small plants, three to four above 5,000 L per hour feed. Energy saving is the deciding factor.
What is the storage life of concentrate?
Twelve to twenty-four months ambient in an aseptic drum, depending on Brix and acid.
