Coffee Processing Plant

Instant Coffee Powder Plant :
Instant coffee processing involves pre-treatment, roasting, extraction, separation, aroma recovery, concentration, drying, and the agglomeration.
1)Cleaning & Grading:
The first step involves a thorough cleaning, removal of defective beans and  grading  of different types and sizes of beans to ensure the best flavour.
2)Roasting & Grinding:
The second step involves roasting through either batch or continuous roasters. The degree of roast can be varied depending on the variety of coffee and blend composition, to develop the desired characteristics of flavor and aroma.
3)Extraction:
Roasted coffee has special aroma withstand relatively low temperature. Traditional extraction process loses the coffee aroma, so the coffee''s aroma is not enough. In a lot of process, they add food additives to improve the taste of coffee. Coffee lost its own attractive as nature''s drink.
Our extraction process keeps the maximum nature aroma. The extracted aroma will be separated by flash separator and stored separately.
The extract section normally included six to eight extraction columns. Each extraction column is designed to withstand 25bar pressure, easy residue-discharging device and controlled by advanced technology.
Our special design increases the solid contents of the extract from 12-13% to 18-22%, so to reduce the investment of downstream process and decrease energy consumption.
4)Aroma Recovery:
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. The flavor is returned just prior to the spray dryer.
5) Spray Drying
With many years of research, we have developed special technologies and designs to meet different requirements of the product, such as product size, bulk density and flowability etc. In traditional coffee spray dryer, fluidized bed is generally a combination of external cooling dry. The traditional coffee spray dryers have external fluid beds for drying and cooling. Our design has inner fluidized bed to make the product meets the requirements of moisture contents and packing temperature.
The particle of final product from spray dryer is normally within the range of 100-350 micron, varies as per the configuration of the plant, processing parameters, and scale of the plant etc.
Our special design also increased the product collection rate. As per the parameters from our customers, the highest product collection rate is around 99.7%.
