Problems solved by technology

In the prior art, the production of potato starch must use a bleaching process to bleach the potato starch, and the bleaching process requires the use of a large amount of bleaching agents, resulting in a large amount of waste water in the production process, which pollutes the environment and must be discharged after harmless treatment.

Embodiment 1

[0019] (1) Choose potatoes with high unit yield, strong disease resistance, large potatoes, high starch content, uniform starch grain size (fast sedimentation), less soluble protein, thin skin, low fiber content, and fresh and ungerminated potatoes; The potatoes are brushed off the soil and impurities through the brush cleaning machine, and the soil and impurities and the potatoes that are too small are discharged;

[0020] (2) The potatoes that have been removed of soil and impurities enter the cleaning and stone removal machine for cleaning, and use running water to wash and remove stones 5 times, wherein the cleaning water pressure is greater than or equal to 3mpa.

[0021] (3) The potatoes that have been washed many times are crushed and ground, and the cells of the material are broken as much as possible to release more free starch granules. The amount of crushing feed should be kept uniform. When crushing, add 2 times the amount of potatoes, grind and crush, and pass thr...

Embodiment 2

[0027] (1) Choose potatoes with high unit yield, strong disease resistance, large potatoes, high starch content, uniform starch grain size (fast sedimentation), less soluble protein, thin skin, low fiber content, and fresh and ungerminated potatoes; The potatoes are brushed off the soil and impurities through the brush cleaning machine, and the soil and impurities and the potatoes that are too small are discharged;

[0028] (2) The potatoes that have been removed of soil and impurities enter the cleaning and stone removal machine for cleaning, and use flowing water to wash and remove stones 6 times, wherein the cleaning water pressure is greater than or equal to 3mpa.

[0029] (3) The potatoes that have been cleaned many times are crushed and ground. The amount of crushed feed should be kept uniform. When crushing, a certain proportion of Physalis is added for grinding and crushing. Each grinding is passed through an 80-mesh Robust sieve. To remove the fiber, unground tissue a...

Embodiment 3

[0034] (1) Choose potatoes with high unit yield, strong disease resistance, large potatoes, high starch content, uniform starch grain size (fast sedimentation), less soluble protein, thin skin, low fiber content, and fresh and ungerminated potatoes; The potatoes are brushed off the soil and impurities through the brush cleaning machine, and the soil and impurities and the potatoes that are too small are discharged;

[0035] (2) The potatoes that have been removed of soil and impurities enter the cleaning and stone removal machine for cleaning, and use flowing water to wash and remove stones 6 times, wherein the cleaning water pressure is greater than or equal to 3mpa.

[0036] (3) The potatoes that have been washed many times are crushed and ground. The amount of crushed feed should be kept uniform. When crushing, add a certain proportion of Physalis (the amount of Physalis added is 4 times the amount of potatoes) and grind. Broken, pass through an 80-mesh Robust sieve each ti...

Abstract

The invention provides a potato starch processing method. The potato starch processing method comprises the following steps: cleaning and removing stones in potatoes, crushing and grinding the cleaned potatoes repeatedly, separating, dehydrating, drying and smashing to obtain the potato starch. According to the processing method, in the crushing and grinding procedures, acid slurry is added to avoid the oxidation of the potatoes and a physical method of controlling water pressure and amount is used in the separating procedure to totally separate impurities from the starch primary slurry; through the physical method, the anti-oxidation effect is realized. In the processing method, a bleaching process is eliminated, so that the use of bleaching chemical agents is avoided, the addition of the bleaching chemical agents is prevented, the environmental protection purpose is realized, the procedures are simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to a starch processing technology, in particular to a potato starch processing method. Background technique [0002] Potatoes are tuber crops. The stems buried in the ground are swollen and contain a lot of starch, which can provide rich nutritional energy for the eaters. It can also be used as a high-quality raw material for the production of potato starch. [0003] The ingredients contained in general fresh potatoes: starch 9-20%, protein 1.5-2.3%, fat 0.1-1.1%, crude fiber 0.6-0.8%. Nutrients contained in 100g potato: energy 318 kJ, calcium 5-8mg, phosphorus 15-40mg, iron 0.4mg-0.8mg, potassium 200-340mg, iodine 0.8-1.2, carotene 12-30mg, thiamine 0.03~0.08mg, riboflavin 0.01~0.04mg, nicotinic acid 0.4~1.1mg. [0004] Potato tubers contain a lot of starch. In the prior art, the production of potato starch must use a bleaching process to bleach the potato starch, and the bleaching process requires the use of a large amount o...
