Difference between simple cassava starch production line and automatic production line

The production process of cassava starch is mainly organized by washing, grinding, screening, separating proteins, dehydrating and drying of raw materials. The main differences between the traditional simple cassava starch production line and the modern production method is that the latter uses a disc separator or a hydrocyclone station instead of the launder to separate impurities, and uses a peeler centrifuge and a flash dryer to achieve automate and continuously operation of cassava starch production line to achieve a mass production.

Simple cassava starch production line

So what is the difference between a simple cassava starch production line and an automatic cassava starch production line?

1. The production process of traditional simple cassava starch production line

1). Washing and grinding: The washing process of cassava is carried out in a washing machine, and some simple production lines with small processing capacity are also manually washed. Mainly for removing impurities such as mud, stones, stems and leaves and muddy sand adhering to the surface of cassava. The water consumption is about 2-3 times that of the raw material. After washing, it is sent to the grinder for treatment. In simple cassava starch production line, the grinder used has both a toothed plate type and a hammer type.

2). Screening: The coarse cassava slurry that has been ground need to be screened. The simple cassava starch production line mainly use a flat shaker or a cylindrical crucible. The starch processing plant normally adopts a curved mesh extruder or a centrifugal sieve. In the screening process, water is added for washing, and the sifted material is starch milk. The washed starch slag can be used as feed or brewing raw material.

3). Sedimentation or launder separation: In simple cassava starch production line, the starch slurry from the screening section is first precipitated in a sedimentation tank or a trough, the crude starch is taken out, and then the coarse starch is reprecipitated or rinsed.

4). Dehydration and drying: After the starch is washed, the water content is pretty high. The filter bag can be used in simple cassava starch production line for lifting and filtering, and the water inside can be filtered out, and then dried by sun drying or drying in a drying room and a dryer. It can also be used for direct processing. Fans and other powder products.

Automatic cassava starch production line

2. Automatic cassava starch production line production technology

The automatic cassava starch production process is basically similar to the simple one. The main differences are as follows:

1). The cleaning stage adopts multi-stage cleaning and washing. Sometimes the larger automatic cassava starch production line also uses the trough to transport or wash the raw materials.

2). Grinding section is complished by rasper. This is an advanced starch grinding machine which can achieve an breaking rate of more than 95%. Rasper used in DOING automatic cassava starch production line adopts Germany Optibelt and Sweeden bearing.

3). The screening equipment of the cassava starch slurry is separated by a centrifuge sieve. And the pulverization and separation are generally carried out continuously which prevent starch browning due to exposure in the air and thus ensures the quality of starch.

3). Use a disc separator or hydrocyclone station is ued in automatic cassava starch production line to replace the launder or sedimentation tank to separate the protein: the separated and refined starch concentration can reach 20 Baume, and then dehydrated and dried to obtain dry starch.

4). There are equipment connections between the various processes of the entire automatic cassava starch production line, reducing manual operations.

The simple cassava starch production line is low investment, less risk, but product quality is relatively poor. The automatic production line ensures high starch quality but the investment is relatively high. When choosing cassava starch processing equipment, purchaser can choose cassava starch production line according to the economic conditions and market positioning. If the budget is limited, a simple production line can be selected, but room should be leaved for further development in the equipment layout, so that equipment can be increased later, improve processing efficiency and product quality.
