The invention discloses a technique for processing nutritional health-care bean curd skin, which comprises the following steps of: cleaning, crushing and soaking soybean, separating soybean milk and dreg, heating, performing secondary milk and dreg separation, putting the obtained soybean milk in a drying box, drying the soybean milk to obtain bean curd skin, and cutting the bean curd skin. The technique has direct current flows; and the whole process from soaking the raw material to pulping, boiling and feeding in the drying box is of self flowing mode. Manpower and power are reduced, and fault rate is reduced. A vehicle-mounted drying box is adopted in the technique, and the drying vehicle has small floor area, so the area of a drying chamber is saved. The drying box is cast by using a die and made of polyethylene acrylonitrile butadiene styrene (ABS) material and has smooth surface, so the drying box is favorable for stripping and cleaning. Compared with the prior art, when products of the same number are processed, the technique can save work efficiency by 6 times, save soybean by 30 percent, save coal by 50 percent and save water by 95 percent. In the technique for processing the product by using the soybean containing 13 percent of water, the yield is 76 to 80 percent, the water content of the product is 8 to 10 percent, and the rest moisture is evaporated during processing the product and then reclaimed. After the produced soybean dreg serving as a byproduct is squeezed and drained, the rest soybean dreg is dried by using waste heat of a boiler flue, and the dried soybean dreg is a raw material for multiple products, so the utilization rate of the soybean reaches 100 percent. By the technique, chemical additive is not added during processing of the product, and zero discharge during production of the product is realized.
