Manioc starch production line

Manioc starch is produced by wet-milling of fresh cassava roots in manioc starch production line. Manioc starch is the main constituent of cassava roots. The process of manioc starch extraction in manioc starch production line is relatively simple than corn starch wet milling process as there are only small amounts of secondary substances, such as protein, in the roots.

Our company is professional manufacture the manioc starch production line . The whole manioc starch production line  is automatic and comprised of 12 units as below:

1. Raw material receiving unit in manioc starch production line

Material receiving unit is the first link of cassava starch processing. The primary purpose of this unit is the cassava preliminary removing impurity and the smooth storing in inside of raw material storage tank. Cassava is conveyed to the cassava yard after weighing by wagon balance, and then is conveyed into the cassava storage hopper by forklift.

The key of this unit is to remove sand and other impurities of cassava during the harvest, the sand stick to the cassava can drop through the screen.

Attention must be taken that cassava should not be damaged in cassava purchase. Damaged cassava is easily decayed, and decayed cassava is vulnerable to infect around cassava. Bad cassava material has a big influence to starch quality.

2. Cassava cleaning and washing unit in manioc starch production line
Clean raw materials for cassava processing play an important role, so de-stoning and cleaning unit of pre-treatment stage is the most important. The purpose of this unit is to get rid of sandstone, clay of cassava, and to deposit cleaned cassava in the cassava temporary hopper.

Cassava is conveyed into the washer, blades washer adopts counter-current cleaning principle. Water flow (used for washing) and the materials movement direction is opposite. Certain level of cleaning water is poured into the cleaning trough, cassava raw materials almost float on the surface of water and move forward through internal trough. The cassava rotates and clashes each other in the water, getting rid of the soil and impurities on the surface of them in the greatest degree.

After washing , the cassava fall into the crusher through the belt conveyor to carry on the preliminary slicing of cassava tuber. Cassava is cut into small piece to ensure crushing efficiency of crushing machine.

3. Cassava crushing unit in manioc starch production line

After washing , the cassava fall into the crusher through the belt conveyor to carry on the preliminary slicing of cassava tuber. Cassava is cut into small piece to ensure crushing efficiency of crushing machine.

Crushing unit is the most important link to influence cassava starch extraction rate. Efficient crushing machine can release cassava starch particles from cassava cells thoroughly, guaranteeing the combination starch content of cassava residue to the minimum.

Cassava slurry below the crushing machine is pumped into de-sanding unit with a fiber pump.

4. De-sanding unit  in manioc starch production line

Cassava slurry got from crushing is pumped into the de-sand cyclone through a fiber pump. Materials with certain pressure enter into the de-sand cyclone along the tangent, cassava slurry in the hydro-cyclone is rotating with high speed, light starch and cassava residue etc. overflow from the top of the hydro-cyclone, while heavy sand is discharged from the bottom of the hydro-cyclone. At the bottom there has a sand catch pot which connects pressure recoil water to guarantee starch not being discharged from underflow outlet, and the sand in the sand catch pot is discharged regularly through air valve.

5. Centrifugal extraction unit in manioc starch production line

Centrifugal extraction unit is another key units of the whole cassava starch production line to influence cassava starch extraction rate, good centrifugal screen and process technology can help extract out all the free starch from broken cassava cells.

Extraction unit is a centrifugal sieve group composed by three centrifugal sieves, each centrifugal sieve equips with a fiber pump and a de-foam pump. Cassava slurry came from de-sander enters into the first level extraction sieve, under the action of centrifugal force of sieve basket high speed rotating.cassava starch goes through the screen, and the residue stayed on the surface of sieve basket was thrown away lately.

The front of the sieve basket, has certain pressure flushing water which spays from nozzles to make cassava residue roll continuously, and then extract starch of cassava residue thoroughly. Sieve basket back also designs flush water, but the back recoil water is periodically opened to guarantee pectin and cassava residue non-clogging screen.

Starch milk is pumped to hydro-cyclone for washing by de-foam pump, and cassava residue is pumped to the second stage centrifugal sieve by fiber pump. Cassava residue containing some cassava starch is extracted starch further in the second centrifugal sieve, starchy water is pumped into the process water of the extraction unit by de-foam pump, cassava residue sequentially is pumped to the third stage extraction sieve by fiber pump. Similarly, the third stage extraction sieve still carries on starch extraction, screened materials still enter the process water of extraction unit, and cassava residue is pumped to cassava residue dehydration unit.

Three-grade of centrifugal sieve group can ensure all free starch to be collected to extraction system, making cassava residue not contain free starch, the extraction rate of starch. Unique process design and excellent equipment performance guarantee complete extraction of free starch from cassava residue.

6. Cassava residue de-watering unit in manioc starch production line

Cassava residue pumped from the extraction unit proceeds with de-watering by a centrifugal sieve, the working principle is the same as an extraction sieve. Cassava residue finally is delivered out of the workshop through a screw conveyor, and the water of cassava residue still returns to process water system of extraction unit.

7. Concentrating and refining unit in manioc starch production line

Concentrating and refining unit is the most important one of the whole cassava starch  production line, starch quality can be guaranteed fully in hydro-cyclone refining unit. Impurities of starch slurry will be eliminated thoroughly through physical method, without influencing the quality of starch product.

Starch slurry sieved from the first stage centrifugal sieve enters into the 18 grades concentration hydro-cyclone washing unit, process water pumped from the other end of the hydro-cyclone washes starch with counter current method. The whole hydro-cyclone can be divided into three parts, first starch slurry is de-watered and concentrated through concentrated hydro-cyclone, concentrated starch milk enters into the subsequent washing unit, and then overflowed cell sap enters into two-stage recovery hydro-cyclone for recycling contained starch. The most effluent overflowed out of hydro-cyclone, containing abundant fibrous impurities is discharged directly; a small minority enters into the process water system of extraction unit again. Starch milk of hydro-cyclone is pumped to a stainless steel starch milk storage tank with blender.

Clean process water adds from last stage of hydro-cyclone to mix and wash starch milk, then the overflow mixes with former stage starch milk, washes and separates. Series of counter current washing like this makes fibers and cell sap are discharged out of hydro-cyclone along water. Adopting 13-stage washing can guarantee washing effect of hydro-cyclone, which could remove fiber, protein contained in starch milk better, in this way, the starch milk came from hydro-cyclone has no impurities at all.

8. Fine fiber separation unit  in  manioc starch production line

Fine fiber separation unit is assorted unit to concentration and refining unit; its main purpose is to reduce working pressure of hydro-cyclone. When fiber and impurities in the starch slurry are too much, fine fiber sieve can be opened to discharge part of the fine fiber of hydro-cyclone out of cyclone system to ensure overmuch fine fiber can be discharged from hydro-cyclone.

Waste water containing fine fiber came from the first level of overflow of hydro-cyclone enters directly into inlet of the fine fiber sieve, starch containing in fine fiber is extracted through the fine fiber sieve as extraction unit; the starchy cell sap and starch slurry extracted from the first level of starch extraction sieve together re-enter into the hydro-cyclone, the separated fine fiber directly enters into the cassava residue spiral discharge of dehydration sieve or into the cassava residue de-watering unit together with the cassava residue came from extraction unit.

Fine fiber separation unit plays a good auxiliary function in the working of hydro-cyclone; it can discharge large amount of fine fiber of hydro-cyclone out of cyclone system in time, at the same time it can discharge cell sap on the poor raw material situation.

9. Starch de-watering unit  in manioc starch production line

Starch milk with too big moisture content came from hydro-cyclone can’t directly dry, so first starch milk needs de-water to make starch moisture content be about 38~40%. When centrifuge filter de-watering and after the rotating drum working at a full speed, the inlet valve automatically and periodically opens, the suspension enters into the rotating drum with full speed through the feed pipe, solid content of the suspension is evenly distributed on semi-auto surface by centrifugal force, and liquid is mostly separated by centrifugal separation through filter screen and drum wall holes, discharged through the tangential liquid outlet of machine housing; along with the extension of the feeding time, the thickness of solid material layer inside the drum is also increasing. reaching the scheduled time, inlet valve shuts down automatically and feeding stops. After a certain period of feeding stop time, the flush valve automatically opened, washing water sprays on solid content through a washing water pipe, the flush valve automatically closes after a certain period of time; under conditions of continuous full speed rotating of the rotating drum, liquid content is constantly separated, solid content is fully dried after a certain time of continuous separation. At this time scraper cuts with rotation into solid material layer along the radial direction of the rotating drum, the removed materials to be delivered out of machine through the aggregate trough along the inclined discharge hopper, scraper resets after the discharging. Meanwhile, flush valve opens, washing water cleans filter screen to make it reuse; washing filter ending means that a complete operational period is finished, at this moment feeding valve opens again to enter the next cycle period. Filter cake is scraped by scraper and conveyed into the feeding hopper of the flash dryer by the belt conveyor of food-grade.

Because the operation of centrifuge filter is intermittent, therefore two centrifuge filters equipped together work at the same time to ensure the feeding continuity of the flash dryer. Centrifuge filter is characterized by excellent performance, and simple and stable operation. low moisture content of de-watered starch, so it can reduce the energy consumption of subsequent air drying.

10.Air drying unit in manioc starch production line

Air dryer will further dry the de-watered starch to commodities starch required moisture content. Air passes through the filter and is heated to the required temperature by the heat exchanger, and then hot air is sucked into the flash dryer by draught fan. De-watered starch is conveyed to the feeding spiral with hopper, and then conveyed to the feeding inlet of flash dryer through spiral conveyer; starch enters into the cyclone separator through air pipe along with hot air of flash dryer; dried starch separates with air in cyclone separator; wet air leaves cyclone separator and discharged through draught fan. Starch enters into finished product spiral through air locker below the cyclone separator. The big bend pipe flash dryer by special design practically proves that the energy consumption reduces 30-40% than average.

11. Screening and storage unit  in manioc starch production line

Starch is conveyed to the starch well-distribution bunker by finished product spiral, and then the starch is conveyed to the bucket elevator through the leveraged feeder starch below the starch well-distribution bunker, finally the starch is conveyed into the two-way conveying spiral. Starch returns to the starch well distribution bunker through two-way conveying spiral, if the moisture content of starch can’t reach standard; starch enters into the double storehouse vibrating sieve through two-way conveying spiral, if the moisture content of starch can reach standard. The vibrating screen sifts and clarifies dried starch, removes gelatinous and thick grain of the fine starch, makes the fineness of the finished product starch meet the standard. The starch screened enters directly into the stainless steel starch bunker for temporary storage. The sieve mesh number of the selected double storehouse
vibrating sieve its sieve mesh is increasing from top to bottom gradually, and guarantees no blockage of the starch screening and the fineness of starch.

Adopting the starch well-distribution bunker can guarantee the balance of the finished product; starch could reach the moisture standard through the recycling of the starch well-distribution bunker, if the dried starch is too dry or too wet. Especially when the flash dryer is under the unstable starting up condition, the moisture content of starch can be ensured to reach standard equally through the starch well-distribution bunker.

12. Weighting and packing unit in manioc starch production line
The starch of storehouse will be packed into 25 kg or 50 kg per bag by automatic packing machine .
