Problems solved by technology

For example, the invention patent of application number 201210344773.2 is a dried sweet potato and a production method thereof, which comprises the following steps: selecting a high-quality sweet potato with a red heart as a raw material; Soak in a mixed solution of calcium chloride and 0.3% sodium bisulfite for 2 hours, take it out and wash it; add honey to boiled sweet potato strips for 10 minutes, rinse with cold water; bake the boiled sweet potato strips at 60°C for 3 hours, and finally Bake at 35°C for 3 hours. The biggest limitation of this technology is: after the sweet potato has just been harvested, because a large amount of its nutrients are starch, and the starch has not yet been decomposed into sugar, the dried sweet potato contains less sugar, resulting in Poor taste of dried sweet potato

Therefore, when making dried sweet potatoes, it is often necessary to store freshly harvested sweet potatoes for 2 to 3 months, which increases production time and reduces production efficiency. In addition, sweet potatoes are prone to fester after being left for a long time, causing unnecessary losses

At the same time, making dried sweet potatoes is often directly cut into strips with sweet potatoes, which are irregular in shape and inconvenient to eat
