Processing of potato vermicelli

(1) Raw material selection: Pick out pest-free, mold-free potatoes and wash away the sediment and dirt from the epidermis.

(2) Starch processing: The washed potatoes are crushed and filtered, and an appropriate amount of spharose is added and stirred (the pulp water is stored separately from the floating water deposited for the first time), and the amount of sour pulp depends on the temperature. If the temperature is around 10°C, the pH should be adjusted to 5.6-6.0; if the temperature is above 20°C, the pH should be adjusted to 6.0-6.5. The precipitated fine powder is quickly removed from the floating water, and the upper layer of black powder is removed. The water is added once more and mixed with a wooden rod. The sediment, drainage, and powder lifting bag are used to increase the viscosity and make the starch white. Place in a closed container and smoke with sulfur.

(3) Snoring and noodles: In the basin, add 2 times the quality of starch and add warm water at 50°C. Add water to stir into a thin powder paste. Pour the boiled water quickly into a thin flour paste. Use a wooden rod to turn clockwise. Stir quickly until the powder is clear and ready to serve. Mix powder meal with wet starch. The proportion of flour meal is 5% in winter and 4% in spring, summer and autumn, and the pasta temperature is about 30°C. When the weather is cold, the bowl is put in a warm water of about 40°C. in. The surface moisture content of the blend is 48-50%, and the total amount of starch is 0.3-0.6% of the total amount of Angelica powder.

(4) Leaking powder molding: Put the powdered noodles into the powder scoop, and then tap the side of the powder to add powder noodles. After the powder line is evenly drained, turn it on the pan again. The distance between the scoop and the surface of the pot is 45-55 cm, and keep the water open by heating.

(5) Cooling and drying: Keep the water in the pot flat with the powder so that the broiled fans can be immersed in cold water. Cooling water should be changed frequently. Fish powder should be light and hanging powder should be uniform. Remove the fans and dry them on the whitefly. After the fans dry, they can be bundled and sold.
