Abstract
The invention relates to a sweet potato powder purification method, and belongs to the field of food processing. The sweet potato powder purification method comprises: (1) placing sweet potato powder into a stirring tank, adding clear water, and uniformly stirring with a stirring machine to prepare a sweet potato powder slurry; (2) pumping the sweet potato powder slurry into a first filter by using a pump to filter, removing the filter residue after filtering, and pumping the filtrate into a second filter to filter to obtain the filtrate so as to be spare; (3) pumping the filtered filtrate into a desanding machine to carry out desanding operation; (4) separating the desanded sweet potato powder slurry with a disc separator, and carrying out dewatering operation after separating to obtain sweet potato powder; and (5) drying the obtained sweet potato powder to obtain the pure sweet potato powder. According to the present invention, the process is improved so as to accelerate the sweet potato powder purification speed, enhance the purification effect, reduce the water consumption and improve the taste of the sweet potato powder.
Description
Technical field
The invention belongs to food processing field, be specifically related to a kind of purifying method of sweet potato powder.
Background technology
The nutritive substance that Ipomoea batatas contains multiple human body needs, every 500 grams of Ipomoea batatas approximately can heat production can 635 kilocalories, containing 11.5 grams, protein (protein food product), 14.5 grams of sugar, 1 gram, fat, 100 milligrams, phosphorus, 90 milligrams of calcium, 2 grams of iron (iron food), 0.5 milligram of carotene, separately contains support one's family B1.B2.C and nicotinic acid, sub-oil (oil food) acid etc.Wherein the content of VITMAIN B1, B2 is higher 6 times and 3 times than rice respectively.Particularly Ipomoea batatas contains abundant Methionin, and rice, flour exactly lack Methionin, but a lot of people but also do not recognize.Ipomoea batatas is difficult for preserving, first how Ipomoea batatas being made to sweet potato powder preserves, or make sweet potato noodles, but also need to make sweet potato powder before making bean vermicelli, in sweet potato powder making processes, because Ipomoea batatas is difficult for cleaning, often contain the impurity such as earth, affect the mouthfeel of sweet potato powder, existing purification process often adopts the repeatedly mode of precipitation, not only waste water, and purification cycle is long, decontamination effect improving is poor.
Summary of the invention
For solving the above-mentioned shortcoming of prior art, the invention provides a kind of purifying method of sweet potato powder, improved the clarification time, improved the effect purifying.
The present invention is achieved through the following technical solutions:
A purifying method for sweet potato powder, comprises the following steps: (1), sweet potato powder is put into agitated pool, by sweet potato powder and water weight ratio 1:(5-10) add clear water, stir with stirrer, make sweet potato powder slurry; (2), sweet potato powder slurry suction the first strainer is filtered with pump, flow velocity is 5-8m3/h, after filtering, removes filter residue, and filtrate suction the second strainer is filtered, and flow velocity is 3-4m3/h, obtains filtrate for later use; (3), by filter after filtrate suction sand removing machine carry out desanding operation, flow is 4-6m3/h; (4), the sweet potato powder slurry after desanding is separated with disc separator, after separation, sweet potato powder slurry is carried out to dehydration operation with water extracter, obtain sweet potato powder; (5), the sweet potato powder in above-mentioned steps is dried to 15-30min with dryer at the temperature of 75-90 ℃, then sweet potato powder is carried out under dry environment to naturally cooling, obtain pure sweet potato powder.
Described the first strainer screen aperture is 160 orders.
Described the second strainer screen aperture is 260 orders.
Beneficial effect of the present invention: the present invention, by the improvement of technique, has accelerated the speed that sweet potato powder purifies, and has promoted decontamination effect improving, has reduced the use of water, has improved the mouthfeel of sweet potato powder.
Embodiment
A purifying method for sweet potato powder, comprises the following steps: (1), sweet potato powder is put into agitated pool, by sweet potato powder and water weight ratio 1:(5-10) add clear water, stir with stirrer, make sweet potato powder slurry; (2), sweet potato powder slurry suction the first strainer is filtered with pump, aperture of filter screen is 160 orders, and flow velocity is 5-8m3/h, after filtering, remove filter residue, filtrate suction the second strainer is filtered, aperture of filter screen is 260 orders, flow velocity is 3-4m3/h, obtains filtrate for later use; (3), by filter after filtrate suction sand removing machine carry out desanding operation, flow is 4-6m3/h; (4), the sweet potato powder slurry after desanding is separated with disc separator, after separation, sweet potato powder slurry is carried out to dehydration operation with water extracter, obtain sweet potato powder; (5), the sweet potato powder in above-mentioned steps is dried to 15-30min with dryer at the temperature of 75-90 ℃, then sweet potato powder is carried out under dry environment to naturally cooling, obtain pure sweet potato powder.
Claims (3)
