Process processing cassava starch from cassava

1. Sharpening grinding cassava into flour porridge

You can use different tools for grinding cassava into flour porridge. Use two hands on the table grinding manioc police cassava grinding sheet metal craft suddenly spikes. Yield 5-7 kg / hour. Using cassava grater with sheet metal crank sudden spikes mounted on rotating shaft. Gruel collecting vessel has flooded the underside of the sheet metal spikes to clean irregular surface grinding. Productivity khong 10-15 kg / hour

- To increase productivity using cassava mill pedal like a thresher. Threshing by hand tooth plate suddenly spikes: axial length 15 -20 cm close khong only medium strength hand to pedal. Lower tilting table rice given to guide the face grinding cassava tubers. Cassava grinding machine foot pedal can yield 100 kg / hour.

- If the traction they have nailed hard wood shaft, small plate instead of sudden spikes. Motorized cassava mill yield 300-500 kg / hour.

2. Filter residue

(Photo: Ykhoanet) - Every part gruel use four parts water to filter out cassava pulp. Microfiltration as smooth, the starch obtained more beautiful. Microfiltration is stretched into a shell or garment bag for easy filtering. Starch with water pass through microfiltration translate powder form. Translation inspired meal at sedimentation tank.

- Cassava pulp used as raw materials for animal feed and poultry.

3. Understanding the starch recovery

Simple can be used in crates lined with plastic pack settled. If less, you can use sedimentation basins, wash the starch.

- Sediment bowls are shaped, wide bottom, not too high. If the tank exclusively used for starch processing, takes away from the bottom nozzle 10-15 cm. Understanding the meal at least 12 hours (usually overnight sedimentation problem), when flour was deposited sure bottom of the tank, use plastic pipe or rubber hose nozzle x to decant water on the surface of the dough. When decanting water disturbs starch.

- Use clean water to wash the starch surface. Surface water is mixed into the dough of flour services to artisanal batches after meal. Then, exposure to boron qun starch. 2.5 to 3 kg of manioc starch bags for 1 kg wet. Percentage of starch obtained depends on the fineness of gruel, filtering techniques and manipulations decanting residue starch.

4. Preservation of wet starch

Wet starch preserved ang, jars, jars, tanks, plastic bags. Qun bo as confidential as long starch.

- If the bulk, wet starch contained in sealed plastic bags and buried underground to pillow cases.
