How to Make Freeze-dryer Coffee

"Freeze dried coffee" is a kind of instant coffee obtained by Labsnova's freeze drying machine technology, which can preserve the original flavor of coffee. And convenient to use, easy to carry, anytime and anywhere can be brewed, deeply sought after by the majority of coffee lovers! Freeze-drying mechanism To make freeze-dried coffee requires certain technology.

"Freeze dryer" in the coffee production process, process: coffee roasting → extraction → concentration → pre-freezing → freeze drying → weighing → packaging. The specific process is as follows:

(1) Coffee extract: completed in the extraction workshop;

(2) Frozen concentration: frozen concentration equipment, under low temperature conditions to freeze the extraction liquid, the ice crystal separation and removal, to obtain frozen concentrated liquid;

(3) Pre-freezing: through the freezing equipment, the freezing temperature is about -50℃, rapid freezing, material freezing thickness of about 1.5cm, to ensure that the freezing is not stratified;

(4) one drying: a drying at -30~0℃;

(5) analytical drying: analytical drying at about 10~60℃;

In the design of freeze-dried coffee, it is very important to choose the equipment of freeze-dried machine, which must meet the requirements of freeze-dried process.

Finally, the "freeze-dried coffee" with water content of about 3% was obtained, and then weighed and sealed.
