Description

Technical Field

[0001] The invention relates to a device and a method for combining pepper cake pressing and extraction, and belongs to the field of pepper cake pressing and extraction tools. Background Art

[0002] In the process of extracting pepper oil, an extraction process is involved. Before the extraction process, the pepper needs to be crushed or broken. The existing pepper raw materials are crushed by a grinder. The high temperature of the pepper during the crushing process causes the volatilization and loss of the pepper's aromatic substances. At the same time, because of the crushing, unnecessary substances such as bitter substances and sugars are extracted in the subsequent extraction process. Therefore, the process is optimized. The cake pressing device is first used to press the cake, and then the extraction is performed. Although such a process can reduce the volatilization and loss of the pepper's aromatic substances, and effectively prevent the extraction of unnecessary substances in the subsequent extraction process, there are still some shortcomings, which are specifically manifested in: first, after pressing the cake, it is inconvenient to take out the pressed pepper from the cake pressing die; second, in the cake pressing process, there is pepper juice after the pepper kernels are pressed. With the long-term use of the cake pressing device, the pepper juice will accumulate at the bottom of the cake pressing die. The oil-containing product of this component is the component of pepper oil. Therefore, if it is not recycled, it will cause losses.
