How Produce Sweet Potato Starch?
Product process of sweet potato starch processing equipment
1,Cleaning materials: small, secondary cleaning. And larger scale, in order to make clean raw material, must use clean cage, so that the impurities such as sand, stone, iron items clean, but also can achieve the goal of saving human and water resources.
2, crushing: using file mill or hammer mill will be fresh potato broken at one time, grain size is moderate, starch granules is big, good quality and yield of high and low, can choose according to need different specifications of the equipment. Especially the hammer mill, it is durable, easy to damage and easy to repair.
3, desanding: now, quite a number of small factory, developed from manual mill production, high sediment concentration in starch, the taste is rather poor, greatly affected the sales and price of starch, dampened the enthusiasm of producers, use our bed cleaning desander, can remove sediment in the starch, make the product quality on a class, this device is simple, obvious effect, can make the starch sediment concentration below 0.3%, and realizes the continuous bed cleaning process.
4, slag slurry separation: slag slurry separation is an important part in starch production, the working procedure and crushing process determines the rate of starch, we put yourself in for the sake of meet ChanFang, since the childhood, designed to produce a series of slag slurry separation equipment.
In terms of small, due to space and economic condition and the restriction of the scale of production and other objective conditions, to produce more, to save money, and slag slurry separation is clean, our company now developed a horizontal long lie sieve, economical and practical. In the mid-sized manufacturer, there is a centrifugal sieve (centrifugal screen speed of 1800 to 2000 RPM), which is used to separate the pulp slag from the centrifugal force generated by high-speed rotation. The large scale manufacturer, adopt today's advanced equipment -- stainless steel pressure curve screen, make the effect of the slurry separation has a further assurance.
At the same time, to make the white degree of starch is better guarantee and increase the rate of starch precipitation, available white equipment - sulfurous acid spray starch, small equipment and manual mill, of course, can also adopt the traditional acid pulp and chemical whitening dosage (must be within the scope of the national food standards)
5, protein separation: in the process of potato starch processing, should be the potatoes contain protein separation, the separation process on the machining process is called purification process. The equipment used is also called purification equipment. It consists of a butterfly separator, a cyclone, that separates the protein from the starch, which is called the yellow powder.
Yellow powder in starch content in the food industry is not very strict, and in industrial starch, especially in the modified starch is quite strict, so if you want to produce the starch of high class, must have a purification equipment as guarantee.
Dehydration: three types of centrifuge, automatic spatula and vacuum filter. The vacuum filter is the best, it not only works smoothly (3-5 RPM), but also the energy efficiency (with 23kw power), the dehydration is also good.
7, drying, drying equipment of the company have a fission type furnace plate spiral air dryers, its characteristic is easy installation, concentrated heating, with heat and energy saving effect is remarkable.
