The invention discloses a continuous extracting and purifying method of a vitamin A intermediate. The purifying method provided by the invention is a crystallization purifying method; a crude product is dissolved in a nonpolar solvent and is refrigerated and crystallized; an impurity in the crude product has strong dissolubility for crystallization; the crystallization rate is low; the energy consumption of low-temperature crystallization is large; and a product is easy to be oxidized to go bad after the crystallization. The purifying method provided by the invention comprises the following steps of: dissolving the crude product of the vitamin A intermediate in a lower alcohol aqueous solution with a volume ratio of 20-90% to form an alcohol-water material, and subsequently, enabling the alcohol-water material to enter an extracting tower continuously, wherein the operating conditions of the extracting tower are that: the extracting temperature is 10-50 DEG C, and the volume ratio of the alcohol-water material to low-polarity extracting agent for extraction is 1: 5 to 5: 1, after 5-20 stages of countercurrent extraction, most impurities are extracted by the extracting agent, and the micro vitamin A intermediate is brought out; and obtaining the purified vitamin A intermediate after the lower alcohol aqueous solution is recovered from the alcohol-water material obtained at the bottom of the extracting tower. The purity of the product obtained by the continuous extracting and purifying method is high, and a subsequent hydrogenation reaction is beneficial.
