Detailed Explanation of the Processing Technology for Millet and Black Sesame Crispy Slices
(1) Formula
900 g millet flour, 100 g black sesame, shortening, and seasonings (salt, white sugar, spicy powder, etc.) in appropriate amounts, plus "Texiangsu".
(2) Process flow
Raw and auxiliary material processing -> measured proportions -> mixing -> dough preparation -> crisping treatment -> sheet pressing -> slicing -> seasoning -> baking -> cooling -> packaging
(3) Key operating points
1. Raw and auxiliary material processing: select clean, hulled fresh millet, wash it thoroughly with water, then soak for 2-3 hours, air-dry, grind into flour, pass through an 80-100 mesh sieve, and set aside. Select high-quality black sesame, carefully remove impurities and shriveled grains, wash clean with clear water, and sun-dry or oven-dry for later use.
2. Measuring and mixing: weigh the processed millet flour and black sesame according to the formula proportions; put them into a mixer and stir until evenly mixed, then add an appropriate amount of boiling water and stir until there are no dry flour pockets, and finally add shortening and stir into a dough of moderate firmness.
3. Crisping treatment: add an appropriate amount of "Texiangsu" to the well-kneaded dough and knead evenly, then let it rest for a few minutes to crisp.
4. Sheet pressing and shaping: after the dough has undergone crisping treatment, use a sheeter to press it into a whole sheet 0.15-0.5 cm thick, then cut it into squares or other shapes.
5. Seasoning: after shaping, spray on seasonings of different flavors, such as salt, white sugar, spicy powder, etc.
6. Baking: after the seasonings are mixed in, place in an oven preheated to 180°C and bake for 4-6 minutes until done.
7. Cooling and packaging: after baking and removal from the oven, cool naturally, then weigh, bag, and vacuum-seal.
