Instant Coffee Plant

Approximately 90% of world coffee production is represented by the species Coffee arabica; about 9% by, the species Coffee Robasta; with minor production from the species Coffee libericia.

SSP has designed and supplied coffee extractors, aroma recovery systems, evaporators, spray dryers, agglomerators to quite a large number of instant coffee manufacturers in India which are running sucessfully. SSp offers the most energy efficient soluble coffee processing technology and are in a position to supply upto 15 TPD instant coffee production plant. Plants with smaller capacities are also available e.g. 50 kg/hr, 100 kg/hr, 150 kg/hr, 200 kg/hr and 250 kg/hr of powder production capacities.

The process consists of following the steps :

1. Cleaning & Blending of green coffee
The first step is through cleaning of defective beans ; blending of different types and sizes to ensure best falvour.

2. Roasting & Grinding of green coffee
The second step is roasting through either batch or continous roasters. Roasted coffee is grinded to suitable size before extraction

3. Extraction
The third step is extraction of ground material through a continous / batch process in a presurised vessel with hot water. To get a better yield (upto 50%) seven batteries of counter column extractor cell is used featuring extraction under closely controlled system.

4. Clarification
The extraction coffee solution is passed through a centrifugal calrifier to separate the insoluble solids.

5. Aroma Recovery
After clarification the extracted coffee liquor is passed through the aroma recovery plant. In the plant the volatile aroma is stripped off from the coffee before it enters the evaporator.

6. Coffee Concentration
The next step is concentration of the extract through multi-effect evaporators with TVR systems upto 50% concentration is achieved.

7. Spray Drying / Freeze Drying
The coffee concentrate is converted to instant coffee powder by spray drying; drying is done under controlled conditions to protect and preserve aroma and falvour.

8. Agglomeration
Spray dried powder can be converted into soluble granules in an agglomerator tower by rewert agglomeration technic.

9. Packing & Filling
The Instant Coffee Powder is taken to the filling and packing stage. There the bins are empted in the filling machine silos. For filling into tines or jars vacuum operated filling system is used. For filling into sachets a form fill-sealing machine is used. Then the filled containers/flexible packing are packed in the shipping cartons and sent for dispatch to the finished goods warehouse.
