Cassava starch production line anf machinery

Here are the complete cassava starch production line:
raw materials cassava-transportation-cleaning-washing-grating-separation-sand removal-concentration and refining-vacuum dehydration-air flow drying-packaging the finished product.
Cassava starch production line

1. Cassava de-stone and washing stage
The de-stone process mainly removes impurities such as small stones, gravel, cassava leaves and other debris. The pretreatment of cassava facilitate the washing stage and reduce the load of washing machine. The washing is mainly used to wash away the sediment, soil and the like attached to the casaava skin. It is required to wash the surface without clay for subsequent processing steps in cassava starch production line.
There is no special requirement for washing water, but from the crushing operation, all processing water should be soft water.

2: Cassava grating: In cassava starch production line, this step determines the starch yield. Grating serves to breaking the structure of cassava to achieve the purpose of releasing free starch. The more free starch, the higher starch yield. DOING cassava grating machine is a high efficient machine with cassava grating rate more than 94%.

3:  Starch and residue separation:
Using centrifuge sieve and fine fiber sieve to separate fibers out of starch slurry. In cassava starch production line, this is also a key step for starch extraction. Multi-stage centrifuge unit is adopted for better effect.

4. Desanding: The specific gravity of mud and sand is greater than that of water, and is also larger than that of starch granules. Hence the separation of sand out of starch slurry by gravity separation is effective. Desander is a cassava starch processing machine serves for this purpose in cassava starch production line.

5. Hycrocyclone refining: Hycrocyclone station is used for concentration, refining and washing the starch slurry so as to achieve the purpose of removing the protein, cell sap and other impurities in cassava starch production line. The extraction is a counter current process. With hydrocyclone station it is possible to reduce protein and cell sap to low levels with a minimum of fresh water. The color or whiteness can be ensured by this process.

6. Dehydrating: After the refining process in cassava starch production line, the starch slurry still contains a lot of water, so it need to be dehydrated before drying. Peeler centrifuge is often used for dewatering. The moisture content of wet starch after dehydration is required to be lower than 38%.

7: Drying and packing: The drying step follows dehydrating to dry starch to the desired quality. By adopting negative pressure drying, the whole process is completed in seconds in cassava starch production line. And this flash dryer is also equipped with cooling system to ensure the moisture uniformity of cassava starch.

What factors affect the price of cassava starch processing plant ？

Image
For the majority of clients who want to set up a cassava starch processing plant, one of their main concern is that: What is the price of a complete set of cassava starch processing machine ? And what factors affect the price of cassava starch processing plant? Let's do a detailed analysis today. cassava starch processing plant Here are the main factors that determines the price of cassava starch processing plant 1. Single equipment or complete set of equipment: The unit price of single equipment is lower, while price of cassava starch processing plant in a whole set is relatively higher. However, it is necessary to consider the processing time, labor cost and other issues. In addition, the production of cassava starch is a complicated process. The single-machine equipment and small equipment occupy a large area and the sanitary conditions are limited. The whole set of cassava starch processing machine features with easy operation, automatic process, saving time and effort, a

How to refine starch from cassava root?

Image
Cassava starch is obtained from the cassava root, which contains high amounts of nutrients such as carbohydrates, fib e r, and vitamins. The starch is characteri z ed by a high amount of antioxidants, a neutral taste, high level of purity, superior thickening characteristics and excellent textural characteristics. How to refine  starch from cassava roots  , the main cassava starch processing line including,   weighing  cassavas tubers, feeding tuber system ,cleaning and washing ,grinding ,separation ,de-sander ,concentration and purification ,de-water ,drying system ,packing system. The details description how to refine starch from cassava roots, as bellows, Step1: Cleaning and washing system Using the dry sieve for remove mud,sand,and first skins, then delivery to paddle washing for washing it,we adopt counter-current washing, and water can be recycling using. Can save some water consumption.   Step 2: Grinding system There is three types of grinding system,one for small scale,it ’ s

Doing Company shipped 5T/H cassava starch production line to Nigeria

Image
Doing Company loading and delivery the cassava starch production line for one of our Nigeria customer in Aug, 2018. This set of cassava starch production line with capacity 5 ton per hour, these machines totally used three container cabinets. Below is the photos of this set of cassava processing machine loading and shippment from our factory: As early as the beginning of 2017, we have connected with this custonmer. After we got his requests for cassava starch processing machine , our engineer customize a suitable plan for him based on his requirement. He is very satisfied with our plan and keep in contact with our sales manager. After a year of negotiations, we received his deposit, letter of credit payment, then we completed the manufacture of set of cassava starch processing machine soonly, and cost 2 days for loading and delivery. Equipment loading The cassava starch processing machine will send to Qingdao port firstly, then from Qingdao port delivery to Nigeria by sea.
