Example Embodiment
[0030] Example 1:
[0031] Buy raw sunflower seeds in the market, manually peel them, soak the raw sunflower seed shells in 40-50℃ water for 60 minutes, rub and rinse with water, squeeze out the excess water with a filter, dry it, and control the moisture at 8%-15%. Obtain raw sunflower seed shell pieces. NaOH (in Na 2 O based on the addition of 17% (by weight of the absolute dry raw material), Na 2 S (in Na 2 O) is added in an amount of 20% (wt% of the absolute dry raw materials), according to NaOH liquid and Na 2 The volume ratio of S liquid is 1:3.5 to configure cooking liquid. Put 100g pieces (based on absolute dry mass) into the cooking pot in 4 layers, pour the prepared cooking liquid between the layers, and the amount of poured increases from bottom to top, respectively, the total cooking medicine 1 / 10, 1 / 5, 3 / 10, 2 / 5 of the volume of the liquid, sealed, shaken and immersed in a pool of 60-70℃ for 60min, shaking frequency times / 15min. Put the small cooking pot directly i...

Obtain raw sunflower seed shell pieces. NaOH (in Na 2 O based on the addition of 18.6% (by weight of the absolute dry raw material), Na 2 S (in Na 2 O) is added in an amount of 20% (wt% of the absolute dry raw materials), according to NaOH liquid and Na 2 The volume ratio of S liquid is 1:3.5 to configure cooking liquid. Put 100g pieces (calculated by absolute dry mass) into a small cooking tank in layers, pour the prepared cooking liquid between the layers, the amount of pour is increased layer by layer, sealed, shake well and set the temperature to 60 Immerse in a pool of -70℃ for 60min, shaking frequency times / 15min. Put the small cooking pot directly into the rotary electric cooking pot, airtight, heat up, heat ...
