How to Retain Flavor Substances of Instant Coffee During Production
How is high quality instant coffee with outstanding dissolvability produced on industrial scale? Many people wonder what kind of processing can deliver instant coffee that dissolves rapidly in cold water while retaining rich original coffee aroma. Today we will walk you through this complete production workflow step by step.
How to Retain Flavor Substances of Instant Coffee During Production
First, filtered coffee extract is steadily fed into our Vacuum Low Temperature Evaporator. The entire concentration workflow is fully automated under precise PLC control. Operators can easily configure parameters to realize stable continuous feeding and discharging for long run mass production. The unit is fitted with an efficient condensing tower. The collected condensate remains crystal clear, free of any coffee solids or flavor components. This clean condensate can be recycled and reused for solvent recovery, helping you cut down raw material consumption and lower overall production costs. Thanks to vacuum assisted low temperature evaporation, coffee liquid will not suffer thermal degradation or discoloration throughout concentration, locking in delicate volatile flavor compounds.

Once concentration reaches the target solid content, the coffee concentrate can be transferred through sealed connecting piping straight into the Vacuum Belt Dryer. This seamless pipeline connection enables fully enclosed, end to end continuous processing, eliminating manual intermediate handling and greatly reducing risks of external contamination and moisture reabsorption. The precision nozzle type distribution system spreads coffee concentrate uniformly across the moving belt. Every layer of material gets consistent heat and mass transfer, achieving thorough even drying with zero color deviation across batch outputs. The complete drying cycle generally lasts approximately one hour under standard operating parameters.
What makes this solution stand out is its integrated built in milling system. All grinding and particle size adjustment operations are completed inside the sealed vacuum chamber. Since powder never gets exposed to ambient air during crushing, it effectively prevents moisture absorption and oxidation. The finished coffee powder comes with low residual moisture, excellent particle flow property, and loose porous structure for superior dissolving performance. Even during long term warehouse storage under regular conditions, the final product stays free from hard lumps and agglomeration, maintaining stable product quality batch after batch.If large-granule products are required, dry granulation can be directly connected to the equipment discharge port to realize in-line granulation.
