The invention provides a processing method for refining rice bran wax by using isopropyl alcohol. The processing method mainly comprises the following steps: weighing appropriate rice bran wax, addingthe rice bran wax into isopropyl alcohol 10 times the quantity of the rice bran wax, and heating for dissolution; adding the rice bran wax mixed liquid after complete dissolution into a cooling tankfor cooling and crystallization; filtering the rice bran wax mixed liquid by a filtering device to obtain rice bran wax particles; mixing the obtained granular rice bran wax with activated carbon, adding into isopropyl alcohol 10 times the quantity of the granular rice bran wax, and performing mixing, heating and decoloration; adding the rice bran wax mixed liquid after complete dissolution into the cooling tank for cooling and crystallization; filtering the rice bran wax mixed liquid by the filtering device to obtain the rice bran wax particles; drying and moulding the rice bran wax particlesobtained in the above step to obtain white refined rice bran wax. The processing method provided by the invention has the advantages of reasonable design and simple processing technology; through themethod, the processing means of refined rice bran wax is increased, and the purity and decoloration effect of the refined rice bran wax are also improved.
