High Efficiency Manufacturers Instant Coffee Powder Production Line
drying chamber to the bottom, the water will be evaporated to and the product becomes powder or granular product.
Induce hot air from the top of drying tower, at the same time, pump the material liquid to the top of the tower by screw pump or
peristaltic pump, the feeding solution becomes into fine beads or small droplets through the atomizer. When the droplets meet the
high temperature hot air, the water will be evaporated immediately, and the material liquid is dried into dry product in a very
short time, the product is discharged from the bottom of the drying tower, or from the cyclone (depend on the configuration). When
the hot air contacts with the droplets, the temperature declines significantly, and the humidity increases greatly, and then will
be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices
There’re different fine powder separation and recovery devices, such as cyclone (the common type and various combination type),
bag filter, cyclone + bag filter, cyclone + wet scrubber, and bag filter + wet scrubber etc. We should different fine powder
separation and recovery devices as per the characteristics of product and requirements of customer.
Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid
bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier.
1. 1 Raw coffee beans are delivered to raw material tank by Roots fan after sorting and passing through the vibrating screen.
2. 2Raw coffee beans from raw material tank are weighed and
3. Then enter into baking furnace in order to become ripe coffee bean.
4. 4Ripe coffee beans are delivered into ripe material vessel through cooling plate screen with hole.
5. After breaking and weighing, the ripe coffee beans are delivered to extraction pot for extracting.
6. Extraction liquid are conveyed to extraction liquid pot through filtering and cooling.
7. To concentrate the extraction liquid through double efficiency concentrator and then to pump them to concentrated liquid
storage pot.
8. To add assistant material to make match material when the concentrated liquid enter into match material pot.
9. After filtering, the well-matched concentrated liquid mixture are pumped into spray dryer fro spray drying by piston pump.(if
want to process the soluble granule , it can use fluidizing granulator to do it )
10. After matching material, to make a inner packing for the Dry power. (For example: packed in small bags or bottles), after
this, to pack the small bags or bottles in cartons and then to storage them in warehouse.
