Instant Coffee Freeze Dryer
In recent years, increase in consuming promoted changes in the strategic layout of the entire food industry, especially the field of coffee. Instant coffee that used to lose coffee's significant flavor, starting to combine the newly developed freeze-dry technique. Freeze-dry technique brings products to a more convenient and diversified future.
While talking about coffee's flavor and taste, the raw material decides coffee's upper limit, whereas the baking method decides its lower limit. The most initial instant coffee relies more on commercial coffee beans -- Robusta beans as raw materials. The high-temp involved in the making process oxides and dissipates its scent, while consumers brew and enjoy the instant coffee, it tastes with bitter and sourness.
Although, as the development of technique, consumers have higher requests on qualities, the taste of instant coffee in markets are improved a lot, there are still lots to be improved. In order to maximumly keep the aroma of the coffee, the cold brew technique was required.
The process of getting cold brewing coffee normally takes 8-12 hours, with slow brewing of 0-10℃ cold water. After that, coffee will be made into freeze dried coffee powder under minus 40 ℃. By this method, consumers could enjoy coffee better as its flavor are mostly kept.
The principle of freeze-dry technique is based on the change of three states of water. Water has three different states, solid, liquid and gas. These three states could convert to each other and can exists on the same time. Fresh food could be frozen by freeze dryers in a short-period of time, and under the proper vacuum environment, frozen water molecules could sublimate as vapor. This process is so be called as freeze drying.
The advantages of Freeze-dried coffee
Preserve the original coffee flavor
The liquid coffee is rapidly frozen and then the moisture is extracted under vacuum to produce freeze-dried coffee. This process is more effective at preserving the flavor and aroma of coffee than typical spray drying, and it tastes more like freshly ground coffee.
Long-term storage
Coffee that has been freeze-dried has a long shelf life and is not susceptible to deterioration because all moisture has been removed. The flavor stability can be preserved for a considerable amount of time even after opening.
Easy to carry
Freeze-dried coffee is usually in powder form or small granules. It is lightweight and easy to carry, especially suitable for traveling, camping or use in the office.

Frequently Asked Questions
How does the KFD-100 freeze dryer work?
+
-
We freeze the brewed coffee and then put it under a vacuum, which lowers pressure and allows the ice to sublimate directly from solid to gas. This process effectively dries the coffee while preserving its flavor and aroma, and it usually removes about 99% of the water content, allowing it to be kept fresh for extended periods of time without needing to be refrigerated.
How long does it usually take to freeze-dry coffee?
+
-
The duration of the procedure varies from 20 to 40 hours, contingent upon the volume of coffee and the particular parameters employed. Before taking the coffee out of the machine, make sure it has fully freeze-dried. It is advised to increase the drying period by two hours at a time if the coffee isn't completely dry.
How to maintain the freeze dryer?
+
-
Due to the complexity of the equipment, regular maintenance and upkeep is very important, including inspection of the vacuum pump, cleaning of the condenser, and calibration of the control system. This extends the service life of the equipment and ensures the stability of the freeze-drying process.
