Processing Technology of Tapioca Starch

Cassava receiving --- cleaning --- rasping and grinding --- sanding --- sieve extraction --- cyclone concentration --- starch washing --- scraper dehydration --- air drying --- finished packing - - Commercial starch

The main stand-alone equipment

1.The raw material receives the cleaning unit

Application:

The paddle washing machine is used to wash the raw material mainly in the production of starch, potato starch, etc.

Features:

1.Adopting countercurrent washing principle makes cleaning and eliminating the sand and mud effectively. 

2. Running smooth and low material breakage rate, reasonable feeding way makes the equipments layout properly.

3. Easy operation, energy and water saving; advanced structure design, easy for maintenance.

2.Crushing unit
   Filing mill



Performance and use

Rasp mill is widely used in starch processing industry, the material is rasher broken. Starch production line is the key stand-alone equipment

Rasp unit is the most important link of influence of cassava starch extraction yield.Efficient file mill can let cassava starch granules in the cells completely released, ensure that the combination of the potato residue in starch content down to a minimum.

Equipment performance and advantages

1. Easy to replace the file, no special tools

2. In the case of guaranteed capacity, lower energy consumption

3. File thickness of 1.25mm, to ensure a longer service life

4. All stainless steel, reasonable structure, easy maintenance

5. The new bearing and bearing room design, to avoid the possibility of sundries into the bearing, effectively guarantee the service life and performance

6. The use of more efficient sieve and block out of the design, easy to operate

7. Stable operation, high breaking rate

3.Sand removal unit
  Sand removal cyclone

Application:

De-sanding cyclone functions as key equipment in starch process for removing sands and other heavy particles from rasp slurry after rasper.  It works before starch extraction process, which can protect the equipment thereafter, prolong the whole production line operation life, and improve starch quality.   De-sanding cyclone can be used to remove heavy particles from other fluids as well.

Features:

1. Unique ceramic cyclone tube for high efficiency and durability.

2. full-automatic sand discharging system by pneumatic control and special ballonet valve, accurately controlled.

3. Wholly in stainless steel (can be partly in carbon steel upon customer’s request.)

4.Sieve extraction unit
    High efficiency centrifugal sieve

Application:

Centrifugal Sieve is  separate the fine fiber from starch slurry after rasping and desanding process for higher starch extraction rate, It is developed by the international leading technology and large numbers of experience. It also can be used for wheat and bean starch extraction.

Feature:

1.Stainless steel sieve plate and multi-layer composite screen ensure long service life, high efficiency, and meet food grade starch requirements.

2.Independently developed de-foaming pump and low-placed motor can ensure the stable performance.

3.Completely closed combination structure, no intermediate tanks needed.

4.Counter current washing and separating, less water consumption.

5.The washing unit is concentrated
   Multi - stage cyclone station

Application:

Multi-stage Hydrocyclone Unit is widely used in concentration, rinsing and refining of starch milk as key equipment for removing soluble and insoluble protein, fine fiber, sugar and etc. It realizes all-in-one functions from concentration, recovery, cleaning and fine fiber separating.

Feature:

Adopt combination system of single cyclone tube made of FDA approved material, for easy maintain and low cost.  It also utilize medium-high pressure for higher rinsing efficiency.

 The specially processed surface is made of SS material of wholly oil and dirt resistant. The hydro-cyclone chamber adopts the best seal technology to avoid leakage, ensures that the material is not contaminated.

Centrifugal pump specially developed for potato starch with shrouded impeller guarantees the stable performance. Combined with the automatic control system, high quality products can be achieved.

Different types of hydro cyclone are available for different raw materials.  They feature easy operation and maintenance.

6.Dehydration unit
   Scraper centrifuge

Performance and Application
After washing the starch milk have high water content and is not suitable to be dried directly. So it need dewatering first to meet the requirements on the inlet moisture of flash dryer and then be dried.
The working principle of Peeler centrifuge is as follows: when the drum runs at full tilt, the valve of the feed inlet will open automatically and thus stalk milk flow down the feed tube into the inner drum and spread across the inner face of filter cloth due to the centrifugal force.  Liquid-phase particles pass through the filter cloth and are soon taken out,  while the wet starch cake accumulates in the drum.
When the starch cake are accumulated to a fixed level, the valve of the feed inlet will close automatically.The valve of washing inlet will open at the same to release the flushing fluid inside to flush the solid-phase starch cake for a while and then close. The drum subsequently begin spinning again  and during the process solid-liquid particles are dewatered. And the scraper will be activated to scrape in radial direction the starch cake which will fall down collecting chute to the tilted unloading hopper outside and then transferred to the feed inlet of flash dryer. After that the scrape will return to the formal place.Flushing valve opens subsequently and the filter cloth will be flushed and cleaned. Above is a whole working circle.   

7.Drying unit
    Airflow dryer

Application:

The flash dryer is not only suitable for all kinds of tuber starch drying, but also suitable for other heat sensitive powder or flake materials that needs fast drying.

Features:

1. We can provide either high pressure or low pressure drying system according to customer needs. Specially designed drying pipes can reduce the total height and ensure high drying efficiency. Also it is easy to install and maintain.

2. Equipped with heat recycling device to increase heat efficiency; Equipped with automatic moisture adjusting device and product cooling system to ensure product quality.

3. Compared to the traditional technology, it can reduce energy consumption greatly.

8.Automatic Control System

Application:

The automatic control system is developed based on our equipment by SGT independently.  By collecting processing parameters and displaying working-status, the system enables starch processing equipment to work efficiently under the optimum processing conditions. Long time practice has proved the high efficiency of the system.

Feature:

1. Key instruments available: SIEMENS (Germany), E+H (Germany), OPTO (USA) international famous brands.  

2. Automatic / manual double control system to guarantee the stability and continuity of production.
