Vacuum freeze-drying technology is to freeze the substance containing a large amount of water into a solid, and then sublimate the solid water under vacuum conditions, while retaining the substance itself, so its volume remains unchanged after drying.

Freeze-dried instant coffee fully restores the flavor of coffee, does not cause "allergic reactions" to coffee at the physical or chemical level, and avoids the loss of some nutrients, but the production cost is higher than that of ordinary instant coffee.

Freeze-dried instant coffee is to freeze the coffee liquid into a solid state at a low temperature of minus 30 degrees, and then change the environment of the solid coffee through a freeze dryer to sublimate the water molecules inside, leaving only soluble coffee. This method of low-temperature freeze-drying can preserve the nutrition and flavor of the coffee liquid to the greatest extent, is the production technology of convenient coffee with the longest shelf life and the most stable flavor.
