The mature fruits are harvested in summer, the pulp and shell are removed, the seeds are taken out and dried. Bitter almonds are mostly cultivated in low mountains or hilly areas. Generally, they have certain medicinal value after processing. In the process of drug production, bitter almonds are often used in a variety of drug formulas due to their unique medicinal value. However, bitter almonds need to be peeled before use to remove their outer epidermis. This process is crucial to ensure the quality of the final product. The current technologies include peeling using mechanical friction or chemical solvents, but these methods have problems such as low efficiency, environmental pollution and possible damage to the intrinsic quality.

[0003] One existing technology is to use cold and hot air treatment to remove the skin of bitter almonds. The specific operation is to first send the bitter almonds with a uniform trace of water on the surface into a cold air treatment box, apply cold air at minus 30-50℃ for 5-30 seconds, and then send them to a hot air treatment box, apply hot air at 300-400℃ for 5-30 seconds to achieve rapid peeling. Although this method improves the peeling efficiency to a certain extent, it still has the following disadvantages:

[0004] 1. Temperature control requires strict requirements. Too high or too low temperature may affect the peeling effect and the quality of bitter almonds.

[0005] 2. Long processing time may lead to energy waste and reduced production efficiency.

[0006] 3. The control of the spraying pressure lacks precision, which may cause physical damage to the bitter almonds.

[0007] 4. The process parameters have not been optimized, and it is impossible to ensure consistent peeling results between different production batches.
