Embodiment 1

[0023] Soak fresh sweet potatoes in water until the sediment on the surface is loose. Generally, after soaking for 20-40 minutes, you can use a squirrel cage potato washer to wash away the sediment on the surface of the sweet potatoes, and then use a brush potato washer to scrub the surface of the sweet potatoes to remove the sediment, and then wash the sweet potatoes It is transported to the selection platform, and the qualified sweet potatoes are selected and entered into the pelletizer for pelletizing. Qualified sweet potatoes require no sediment, no insect holes, no rot and no other impurities on the surface. The granulator cuts the sweet potato into small particles with a particle size of 0.5-2.5 mm, then washes the sweet potato with water to remove the starch in the sweet potato, adjusts the concentration of the potato, and dehydrates it with a scraper centrifuge until the moisture content of the sweet potato is Between 50%~60%, present embodiment is 15 minutes with 1000...

Embodiment 2

[0025] Soak fresh sweet potatoes in water until the surface silt loosens. According to the amount of silt on the surface, soak for 20 to 30 minutes in this embodiment, then use a squirrel cage potato washer to wash off the silt on the surface of the sweet potatoes, and then use a brush potato washer to scrub the sweet potatoes. Clear the sediment on the surface, and then transport the sweet potatoes to the selection platform, and select the qualified sweet potatoes to enter the granulator for dicing. Qualified sweet potatoes require no sediment, no insect holes, no rot and no other impurities on the surface. The granulator cuts the sweet potato into small particles with a particle size of 0.5-1.5 mm, then washes the sweet potato with water to remove the starch in the sweet potato, adjusts the concentration of the potato, and dehydrates it with a scraper centrifuge until the moisture content of the sweet potato is About 50%~65%, the present embodiment is with 2000 rev / mins, and...

Embodiment 3

[0027] Soak fresh sweet potatoes in water until the surface silt loosens. According to the amount of silt on the surface, soak for 35 to 40 minutes in this embodiment, then use a squirrel cage potato washer to wash off the silt on the surface of the sweet potatoes, and then use a brush potato washer to scrub the sweet potatoes. Clear the sediment on the surface, and then transport the sweet potatoes to the selection platform, and select the qualified sweet potatoes to enter the granulator for dicing. Qualified sweet potatoes require no sediment, no insect holes, no rot and no other impurities on the surface. The granulator cuts the sweet potato into small particles with a particle size of 1-2 mm, and then washes the sweet potato with water to remove the starch in the sweet potato, adjust the concentration of the potato, and dehydrate with a scraper centrifuge until the water content of the sweet potato is 50% %~55% left and right, present embodiment is with 1500 rev / mins, and ...

Abstract

The invention discloses a processing method of sweet potato dietary fiber powder. The processing method of sweet potato dietary fiber powder comprises the following steps: dicing cleaned sweet potatoes into grains, cleaning by water, removing starch, then dehydrating by a scraper centrifugal machine until the weight percent of water is 50%-60%; baking the dehydrated potato grains by an air flow dryer until the weight percent of water is only 5%-13%; then crushing the potato grains, and screening, thereby obtaining the sweet potato dietary fiber powder. According to the invention, by adopting technologies including cleaning potatoes continuously, sorting manually, centrifugal dewatering by the scraper centrifugal machine, airflow drying and the like, the technology process is shortened and simplified; the production efficiency is improved; the potato residues after starch production can be utilized completely; the cost is reduced; the produced dietary powder can be taken as raw materials to be added into common food, and the comprehensive utilization value of the sweet potatoes is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of food processing, and more specifically, embodiments of the present invention relate to a processing method of sweet potato dietary fiber powder. Background technique [0002] The existing sweet potato dietary fiber technology generally adopts methods such as biological enzymolysis, fermentation, membrane separation, and chemical methods. The extraction rate of enzymatic method is high, but the cost of enzyme preparation is high; the process of fermentation method is complicated and the control is difficult; the purity of dietary fiber extracted by membrane separation method is higher, which can be used for functional food, which is more promising than the first two methods, but the production The process requirements are relatively high; due to the use of chemical reagents in the chemical method, it is easy to cause chemical residues, and there are potential safety hazards.
