This blog talks about Spray Dried Coffee Preparation.
In general, soluble or instant - coffee preparation involves three steps i.e. Roasting, Extraction and Spray Drying.
Soluble coffee is made from coffee beans that have been roasted and ground. The beans are then extracted with hot water to recover the coffee flavor and aroma. The coffee extract is then dried to make spray dried coffee.
In spray-drying, the coffee extract is sprayed into a stream of hot air at the top of a tall cylindrical tower. As the droplets fall, they dry, becoming a fine powder by the time they reach the bottom.
Now let's have a look at the Roasting, Extraction and Spray Drying process at Indus
For fast roasting of coffee for good taste and aroma, Indus Coffee has installed a Turbo Roaster with the latest technology. The Turbo Roaster is fully automatic where the degree of roast is controlled through PLC - roast after roast for uniform roasting.
Both Robusta and Arabica are roasted separately for optimum roasts and blended thereafter as per the consumer/market requirements.
For the extraction process, Indus uses a fully automatic coffee extraction plant from Europe. This coffee extraction plant produces consistent quality of coffee extract batch after batch. Cycle time is kept lower than conventional coffee extraction plants for the finer quality of the product.
Temperatures are kept low when comes to fresh coffee treatment such that thermal damage to coffee is negligible and the end product is of the highest quality.
At Indus low-temperature drying technology is used for spray drying. This ensures minimal loss of aroma during drying. Later the Instant coffee is cooled, classified and packed in airtight tote bins for further packing into bulk or retail packs.
Currently, Indus plant produces 10 different types and qualities of spray dried instant coffee and granulated coffee according to the customized specifications and also internationally recognized standards. With careful selection of raw material and a team of knowledgeable professionals - Indus strives to provide a quality product to all its customers.
