The fat extraction instrument is a fat measurement instrument developed and manufactured based on the principle of Soxhlet extraction. Because Soxhlet extraction is convenient and quick, the fat extraction instrument uses this principle to determine the fat content in foods, etc. It will have more advantages and will be applied more widely. The working process of the fat extractor is to achieve the separation of the target (such as fat) by leaching the sample at the appropriate temperature. The use of a fat extraction apparatus to perform fat extraction can be mainly performed in four steps. 1. Soaking phase The first step is the soaking phase of the sample to be tested. At this time, the sample will be immersed in boiling petroleum ether or anhydrous ether, and most of the solubles will be leached. 2. Recirculation phase In the reflux phase, the sample is lifted above the solvent level and the evaporated solvent is condensed and returned to the filter paper drum to rinse the sample. 3. Solvent Recovery After the leaching is completed, the solvent is recovered in the solvent recovery bottle. Only the solubles to be leached remain in the leach cup. 4. Fat extraction is completed After the fat extraction is completed, the extraction cup is raised and removed from the heating plate to prevent the fat from being oxidized. The above are the four main steps in the fat extraction experiment analysis of the fat extraction apparatus. In general, the fat extraction apparatus is mainly composed of a leaching unit and a control unit. The main function of the leaching unit is to automatically complete solvent leaching. The unit includes a heating plate, a condenser, a solvent addition carousel, a solvent recovery bottle and Buttons and other components; and the control unit is mainly used to set the parameters of the instrument, switch the condensate and display the working status of the instrument to ensure the function of the extraction unit and the normal operation of the instrument.
