Description

Technical Field

[0001] The invention relates to the technical field of pepper oil production equipment, in particular to a pepper oil production device and a production method. Background Art

[0002] Sichuan pepper oil, a seasoning oil primarily derived from Sichuan peppercorns, boasts a unique numbing flavor and aroma and is widely used in the catering and food processing industries. Currently, methods for producing Sichuan pepper oil primarily include traditional leaching, steam distillation, solvent extraction, and supercritical CO2 extraction. However, these methods still present numerous technical challenges in practical application, hindering both production efficiency and product quality.

[0003] Although traditional extraction methods (such as hot oil extraction) are simple to operate, high temperatures can easily lead to the loss of volatile flavor substances in Sichuan pepper (such as limonene, linalool, etc.), and the extraction rate of numbing substances (such as hydroxy-α-sanshool) is low, resulting in a single product flavor.

[0004] Although steam distillation can better retain the aroma components, the extraction efficiency of numbing substances is not high. In addition, the distillation process consumes a lot of energy and has low production efficiency, which makes it difficult to meet the needs of industrial production.

[0005] Although organic solvent extraction (such as ethanol and petroleum ether extraction) has a high extraction rate, there is a risk of solvent residue, which affects food safety. The subsequent solvent recovery process is complicated, which increases production costs.

[0006] Although supercritical CO2 extraction can efficiently extract the flavor and numbing components in Sichuan pepper without any solvent residue, it requires large equipment investment and high operating costs, making it difficult to promote and apply in small and medium-sized enterprises.

[0007] Furthermore, existing peppercorn oil extraction equipment generally suffers from low automation levels and imprecise control of extraction parameters (such as temperature, pressure, and time), resulting in inconsistent quality across batches. Furthermore, the lack of standardized pretreatment of the peppercorn raw material (such as degree of pulverization and moisture content) further impacts extraction efficiency.

[0008] Therefore, developing an efficient, low-cost, and highly automated device and method for producing pepper oil to improve the extraction rate and quality stability of pepper oil while reducing energy consumption and production costs has important practical significance and application value.

[0009] For example, the Chinese patent application number is 201906003383: A production device for preserving peppercorns and producing peppercorn oil: The technical proposal discloses a pepper production device, which produces pepper oil through the method of "pasteurization and cleaning - dehydration - heating vegetable oil - frying pepper in vegetable oil - vibration deoiling - air cooling and oil blowing + air drying - pepper frying and filtering - dehydration of pepper oil". Obviously, this technical solution cannot achieve the claimed technical effect. First, pasteurization before frying will cause the core flavor substances of Sichuan pepper (such as limonene, linalool, eucalyptol, etc.) to be heat-sensitive components. These substances will partially volatilize or decompose, making the aroma of the finished Sichuan pepper oil lighter and the layers reduced. It also adds multiple processes such as sterilization and drying, which has a high time cost and is not suitable for rapid industrial production. Summary of the Invention
