AI Technical Summary
Existing freeze-drying methods for peppermint leaves cannot produce extract blocks, and the powdered form is inconvenient for consumption.
A system including devices for chopping, grinding, pulping, concentration, and freeze-drying was designed to prepare peppermint extract blocks by chopping peppermint leaves, mixing with ethanol, concentrating, and vacuum freeze-drying.
The prepared peppermint extract blocks retain the integrity and flavor of peppermint components, and have the advantages of being aesthetically pleasing, portable, stable, and able to be stored at room temperature, while also improving production efficiency and automation.
