Problems solved by technology

In the process of waste water recycling, the clean production technology of sweet potato starch collects the waste water from four different production sections, and returns it to four different production sections in the sweet potato starch production process after treatment, so as to save water and not discharge sewage. Purpose; In addition, the sweet potato residue after starch extraction is processed by enzymatic hydrolysis and other processes to produce dietary fiber products with high added value, improve the comprehensive utilization value of sweet potatoes, and achieve the purpose of clean starch production; thus effectively solving the problem of existing traditional starch The industrial problems of high cost, low value and heavy pollution of starch production during processing

Embodiment 1

[0031] A processing method for clean production of sweet potato starch, comprising the following steps:

[0032] a. Raw material cleaning:

[0033] Put the fresh sweet potatoes into the soaking pool, add water to soak all the fresh sweet potatoes in the water for 0.5h; send the soaked fresh sweet potatoes to the potato washing machine for washing with water, and send the cleaned water to the waste water pool through the pipeline ( ready for recycling);

[0034] b. Refining:

[0035] The fresh sweet potatoes that have been washed (and selected, that is, the bad ones are picked out and discarded) are crushed and refined with a refiner (the crushing amount per unit time can be selected according to different production needs, and the equipment is the existing technology. products), the refining particle size is 10 mesh to 60 mesh, and the sweet potato slurry is obtained; the purpose of crushing is to destroy the tissue structure of the sweet potato, so that the tiny starch gran...

Abstract

The invention discloses a processing method for the clean production of sweet potato starch, which is characterized by comprising the steps of raw material sweet potato cleaning, pulp grinding, primary filtering, secondary filtering, precipitation and the like. When the method provided by the invention is adopted, the water used in the starch processing process is cyclically utilized, in addition, sweet potato residues after the starch extraction are converted into feedstuff or processed into dietary fiber food, the final waste water generated through processing is changed into irrigation water and precipitated silt to be returned into the field for being used through environment-protection treatment, the additional value of the potato products is improved, the pollution on the environment is also avoided, the sweet potato residues after the starch extraction are also treated through processes such as enzymolysis and the like, the dietary fiber food with the high additional value is produced, and the integral utilization value of sweet potatoes is improved.

Description

technical field [0001] The invention belongs to the preparation of food or food material, and relates to a processing method for clean production of sweet potato starch. Background technique [0002] Sweet potato, also known as sweet potato ( Ipomoeabatatas Lam) is an important low-input, high-yield, drought-resistant, barren-resistant, multi-purpose crop that is grain, feed and industrial raw materials in China. my country is a big sweet potato country in the world, with an annual sweet potato planting area of ​​6.16 million hm 2 , with a total output of 117 million tons, accounting for 68.1% and 86.8% of the world's planted area and total output, respectively. Sweet potatoes are rich in nutrients, except for containing a lot of starch, Vc, V B1 , V B2 , V E , carotene, dietary fiber and a variety of amino acids (especially the rare lysine in rice noodles is very rich), it also contains calcium, phosphorus, iron, potassium and other minerals, as well as mucus protein, ...
