The invention relates to a production method of Sinkiang quarenden crisp chips. The production method comprises the following steps: performing cleaning, mechanical peeling and slicing on fresh and insect-resistant Sinkiang quarendens taken as raw materials; and performing color protection, blanching, sugar immersion, freezing treatment, primary puffing, secondary puffing, drying and cooling on the sliced Sinkiang quarendens so as to finally obtain the Sinkiang quarenden crisp chips. According to the production method of Sinkiang quarenden crisp chips, the technology of the combination of the primary puffing and the secondary puffing is adopted, so that the diffusion of water in the Sinkiang quarenden chips is accelerated; the puffing degree of the Sinkiang quarenden chips is enhanced, the drying time is shortened, the crisp degree of the Sinkiang quarenden crisp chips is improved. The primary puffing and the secondary puffing are both carried out by simultaneously performing the heating from the front end and the rear end of a heater in a puffing tank, so that the situation that materials are unevenly heated in the original puffing tank is overcome. As a result, the product yield of the Sinkiang quarenden crisp chips is improved, namely, the product yield can reach 98%; the color and the luster of the Sinkiang quarenden crisp chips are improved.
