Coffee Processing Plants and Equipment for the Instant Coffee Industry

SPX  supplies plants and equipment for spray drying of coffee extract with a high quality output of soluble instant coffee powder for the coffee powder industry.

Green coffee bean handling and coffee extract concentration

The initial handling of green coffee beans involves the removal of foreign matter followed by coffee bean roasting and grinding. The preparation of a concentrated coffee extract from the roast and ground coffee beans is performed in a series of high-yield percolator battery columns operating continuously in the so-called dual/dual extraction mode in order to obtain the highest coffee extraction yields and extract quality. This provides a primary extract fraction, which is rich in aroma, and a secondary hydrolyzed extract fraction to promote high-yields. The high-quality aromas in the primary extraction are recovered by flash separation followed by immediate condensing and storage under chilled conditions. All this is to ensure a final high quality instant coffee powder.

The following aspects are important in the process of making soluble coffee powder and should be carefully considered prior to selection of the coffee processing technology:

• The spraying technology (spray drying of coffee powder)
• The types of coffee processing plants
• Technologies for producing freeze dried coffee powder
• The types of coffee aroma recovery systems
• The systems for coffee powder packing
• The water consumption necessary for producing instant coffee

The above aspects should be considered when the producer wish to produce spray dried coffee. SPX  can assist you in all these matters and help you to achieve liquid coffee extracts of the highest quality and to produce the best coffee powder to be enjoyed by your customers.
