Exposure Rate and Storage Capacity
With most of the primary processing methods of coffee, farmers’ experience and many studies have shown that drying coffee is slow ensures quality and helps preserve the flavor of the coffee. When stored in a living form.
Coffee that dries too quickly can lose quality when delivered to the roaster. And above all, this affects both the roaster and the end-user, the diners.
It is more difficult to store than parched coffee because the protective coating has been removed. At this time, the coffee beans will be in direct contact with the air, resulting in a much-reduced quality.
Paddy Shelling and Delivery
Coffee beans are still wrapped in a shell when leaving the processing factory. At this point, the coffee has reached the standard humidity of 12 – 12.5% to store without fear of rotting coffee.
As soon as the order is received, the workers at the primary processing factory will remove the parchment, which protects the coffee beans, but increases the volume of the beans so that they will be rejected—removed to reduce shipping costs.
Once the pods have been separated, the beans are further screened and passed through a color blasting line to remove defective or deformed beans.
Size Classification of green coffee
Sieve is often used to classify the size of coffee beans. We often come across standard sieve sizes in the Vietnam market, such as S14 – S16 – S18.
More giant beans don’t necessarily mean better quality, but grading makes the batch more uniform, so the roaster can have easier control to produce a highly consistent roast.
Peaberry (Culi) is also classified; mononuclear occurs when the ripe coffee fruit has a single nucleus in the middle instead of two. This nut is often said to have a more intense flavor, although this is not always the case.
Packing and Shipping green coffee
Coffee beans at this stage are ready to be stored in 60kg jute bags. In some cases, the packaging material will be changed to suit each locality or serve export regulations.
Coffee is usually shipped by container, with each container holding up to 300 bags of coffee. With low-quality coffee for the instant coffee industry, green coffee can be poured directly into the lined container, as some roasters will pour the container directly into the roasting line on the day of receipt…
The only downside to this transport method is that the unstable ambient temperature can degrade the quality of the coffee inside.
Green coffee extract (green coffee beans)
You’re probably aware of the long-running health debate around coffee consumption. Researchers are split on whether or not the famous brew is healthy. The usage of coffee beans has also sparked debate. Following its appearance on “The Dr. Oz Show,” it became well-known as a weight-loss product.
Green coffee bean extract is derived from unroasted coffee beans. Chlorogenic acids are chemicals found in coffee beans. Some people believe these chemicals have antioxidant properties, decrease blood pressure, and aid weight loss.
