Process description
1 Potato receiving, transporting and cleaning unit
Store the potato in storage pool. Then the de-stone machine will remove the dirt and other foreign matters completely. Finally, store the clean potato in a temporary storage hopper.
2 Potato rasping unit
The rasping unit is the most important part of potato starch extraction. Rasping mill with high efficiency allows the starch granules in the potato cells to be released out completely, which ensures minimum quantity of the remaining starch in the potato residue. The rasping potato slurry is pumped into de-sanding unit by a fiber pump.
3 De-sanding unit
Rasping potato slurry is pumped through the fiber pump into the de-sanding cyclone. When the slurry enters de-sanding cyclone, the light phase of starch and potato residue come out of the top as overflow, and the heavy phase like sands will be discharged from the bottom.
4 Starch extracting unit
Centrifugal extraction is another key unit which infAdvanced technology large economic scale Sweet potato starch production lineces the potato starch yields. The potato slurry enters the first stage centrifugal sieve from de-sanding cyclone, the slurry is separated into starch slurry and potato residue under the centrifugal force. Starch slurry is pumped through the de-foaming pump to the hydro-cyclone station for washing starch, and the potato residue is sent to second and third grade centrifugal sieves through fiber pump for starch recovery.
5 Potato residue dewatering
We use a centrifugal sieve for potato residue dewatering, it works like the extraction sieve. Finally, potato residue is transported out of the workshop, the extracted water return to the process water system.
6 Starch washing and concentration unit
The 16 grade hydro-cyclone station guarantees the quality of the starch completely, which is the most important unit of the entire production line. The starch slurry enters the third stage of the hydro-cyclone for concentration, and the fresh water enters the hydro-cyclone from the other end which washes starch. The overflow enters two grade recovery station to recycle starch, the bottom flow is washed through 13 grade washing cyclone to ensure that the starch slurry does not contain impurities and final starch will be in accordance with national standard .
7 Starch dewatering unit
The starch out of the cyclone station has big moisture so it must be dewatered then dried. The starch slurry enters Advanced technology large economic scale Sweet potato starch production line dewatering filter tank from the starch milk buffer tank. Under the Advanced technology large economic scale Sweet potato starch production line formed by the Advanced technology large economic scale Sweet potato starch production line pump, the starch slurry is sucked to the drum surface, then filtrate goes through filter mesh and enters the filtrate separating tank. The starch cake remains on mesh surface and is scraped off by a scraper and transported by the conveyor belt into the air dryer. Then weighing and packing.
The purpose of denaturation is to adapt to various industrial applications. Such as: high-temperature technology (canned sterilized) requirements of high-temperature viscosity stability of starch, frozen foods require good freeze-thaw stability of starch, jelly foods require good transparency, good film formation and so on. The second is to open up new uses of starch and expand the scope of application. Such as: the use of starch in textiles; hydroxyethyl starch, hydroxypropyl starch instead of plasma; high cross-linked starch instead of surgical gloves with talcum powder.
The Advanced technology large economic scale Sweet potato starch production line manufactured by Jinan Joysun Machinery Co., Ltd. has been specially designed and has adjusted the cavity and screw structure to achieve the diversification of the function of modified starch. The modified starch series produced is suitable for textile, food, paper, building materials, foundry, oil drilling and other fields. With the deepening of research, the extruder will play an increasingly larger role in the modified starch market. Advanced technology large economic scale Sweet potato starch production line consists of a feeding system, an extrusion system, a rotary cutting system, a heating system, a transmission system, and a cooling system.
