Abstract
The invention discloses a supercritical CO2 extraction technology of silkworm chrysalis oil. The technology comprises the following steps: (1) silkworm chrysalis pretreatment: drying silkworm chrysalis, crushing to form silkworm chrysalis powder, and sieving by a 30-60 mesh sieve; (2) extraction: carrying out supercritical CO2 extraction of the sieved silkworm chrysalis powder in an extractor, opening a valve of a separator for the entrance of CO2 containing silkworm chrysalis oil to the separator, and collecting crude silkworm chrysalis oil at the outlet of the separator, wherein supersonic waves can be used to reinforce the silkworm chrysalis oil extraction separating process; and (3) refining: refining the crude silkworm chrysalis oil through a stationary method to obtain refined silkworm chrysalis oil. The supercritical CO2 extraction technology of the silkworm chrysalis oil has the advantages of no organic solvent pollution, simple production technology, high oil yield, and oil yield increase through the use of the supersonic waves to reinforce the silkworm chrysalis oil extraction separating process.
