Problems solved by technology

However, in the prior art, the extraction of dried lotus root starch is mainly based on small workshops, the production method is simple, and the process is not easy to control, resulting in unstable quality
And the crushing process is used to obtain lotus root pulp. The blades of the pulverizer used in the crushing process are relatively uniform, and the edible fiber is cut off relatively finely. During the process of filtering the residue, the dried lotus root starch is also mixed with edible fiber, resulting in low purity of the dry lotus root starch. Not strong enough, bad taste

Embodiment Construction

[0024] Step 1 material selection: choose fresh dried lotus root, wash off the soil and dirty spots on the surface, then cut off the fibrous roots and rotten lotus root, and use the hole piercing device to pierce fine holes densely and evenly on the lotus root;

[0025] Step 2 soaking: Soak the fresh lotus root with saturated lime water, the water temperature is controlled at 30 degrees Celsius, soak for 7 hours, so that the water content of the lotus root is 55%;

[0026] Step 3 squeezing: rolling and squeezing the soaked lotus root pieces in sequence, and fully extracting the starch-containing slurry in the lotus root pieces through rolling and pressing;

[0027] Step 4 Washing: Pour the starch-containing slurry obtained in the previous step into the sieve cloth to filter and rinse, pour the lotus root slurry and add water while stirring, and then use tanks, pots and other containers to receive the dried lotus root slurry until the slurry in the lotus root dregs Until washing...

Abstract

The invention discloses a production process of dry lotus root starch and belongs to a processing technology for agricultural and sideline products. The dry lotus root starch is produced by using dry lotus roots as raw materials. The production process comprises the specific flows of raw material pretreatment, soaking, squeezing, pulp washing, pulp bleaching, dehydration and washing, and drying. The production process has the beneficial effects that the dry lotus root starch is high in purity, small in nutrient loss, pure in taste, short in production period, and suitable for large-scale production; moreover, the production process is easy to control.

Description

technical field [0001] The invention relates to a method for preparing edible starch, in particular to a method for preparing dry lotus root starch. technical background [0002] Dry lotus root, also known as ginger taro and plantain taro, is a perennial plant of the family Araceae, native to South America. The rhizome of dry lotus root is rich in nutritious starch, crude fiber, crude protein, reducing sugar, various trace elements and amino acids, which can be used for medicine, and has the functions of nourishing qi, dispelling cold and damp, nourishing yin and tonifying kidney. The rhizome of dry lotus root can also be cooked and eaten directly, and the starch can be extracted through processing to make a variety of snacks. However, in the prior art, the extraction of dry lotus root starch is mainly based on small workshops, the production method is simple, and the process is difficult to control, resulting in unstable quality. And the crushing process is used to obtain...
