All about Spray-Dried Instant Coffee ✔ 3 min read
There are three types of instant coffee: freeze-dried, spray-dried, and liquid concentrate. Both Freeze-dried and spray-dried were discussed in an Instant coffee article in the brief, so here we focus on the production of Spray Dried Instant Coffee. It is a common method and has more popularity. Spray drying is accomplished by sprinkling liquid coffee concentrated into extremely hot, dry air. The liquid in the coffee has evaporated and dried into little, spherical crystals by the time it reaches the ground.
There 3 general steps for Spray-Dried Instant CoffeeStep 1 This step entails deploying industrial bulk brewers to produce vast volumes of freshly brewed coffee. In industrial brewers, freshly ground coffee is mixed with hot water until the appropriate level of extraction is achieved.
Step 2 The produced coffee liquor liquid is next concentrated using an evaporation process, which removes some of the delicate aroma constituents and stores them for later use before packaging.
Step 3 After that, the concentrated liquid coffee is delivered to the spray-drying tower, where it is powdered. This is accomplished by passing coffee concentrate through an atomizer, which breaks it up into tiny droplets. As the descending droplets come into touch with the drying gases, they start losing their water content.
The powdered coffee can be useful but it frequently undergoes a process known as agglomeration, which produces a more usable and aesthetic product. A partly rehydrated procedure gathers the small coffee particles into bigger particles, resulting in a more aesthetically appealing end product that is between powder and freeze-dried coffee inconsistency.
Spray-dried coffee is far less expensive to produce than freeze-dried Instant Coffee, which is regarded as a higher-quality product and believed to be a more simple (and quicker) procedure. The negative side is that cleaning takes a long time and because high spray drying temperatures are employed, raw materials are subject to degradation.
