This invention discloses a refining method for
camellia oil, belonging to the field of
camellia oil refining technology. It includes deacidification, washing, decolorization, deodorization, and dewaxing processes. During initial
filtration, the
discharge valve,
inlet valve, and turbid oil valve are opened, and the
camellia oil is sent to the decolorization reactor. Observing the
sight glass of the
discharge pipe, if the camellia oil is clear and the color meets the requirements, the turbid oil valve is closed, and the clear oil valve is opened. At this time, the detection valve and
reflux valve are opened, and the qualified product output valve is closed, sending the camellia oil to a vertical blade filter. After a first predetermined time, the
reflux valve is closed. The liquid level in the detection tank rises, and sampling is performed from the detection tank. After sampling, the
reflux valve is opened. If the test is qualified, the qualified product output valve is opened, the detection valve is closed, and the camellia oil is sent to a
storage tank. After the camellia oil in the detection tank is drained, the
reflux valve is closed. The decolorization effect is judged based on the observation results of the
pipe sight glass. If it does not meet the standard, it is sent back to the decolorization reactor for further decolorization. During initial
filtration, sampling is performed; if qualified, it is output to the
storage tank.
