Cassava starch making process and mainly used cassava starch processing machine

As the main cassava deep processing products, cassava starch is extensively used in food, medicine, textile, paper making, feed, chemical and other industries.  But how to produce starch from cassava? Doing Company as an enterprise specialized in cassava deep processing equipment, our engineer can provide a professional and practical answer for you.

Cassava starch making process

Here are cassava starch making process:

1. Raw material cleaning and washing: The first point to process the cassava is cleaning. Dry sieve is widely used for cleaning in cassava starch making process whose main function is to remove sand, mud, leaves and other debris. Then the paddle wash machine is used for washing process which combines flushing with a low water level and continuous removal of dirt and peels. The wash water may be recycled after filtering off peels on a rotary screen and settling of sand in basins.

2. Extraction of cassava starch
Cassava cutting and crushing: The washed cassava tubers are conveyed through conveyor belt to the cutting machine. In this section, the cassava roots are chopped into pieces so as to ensure a properly feeding into the resper. Crushing is an key factors which determines the extraction rate of cassava starch in cassava starch making process. DOING rasper fully absorbs advanced technologies from home and abroad whose breaking rate is more than 94%.

3. Starch and residue separating: These two cassava starch processing machines are used for separate fibers from starch slurry. For theses two machinery, washing water is designed on the front and back of the screen basket to ensure that the screen mesh is not blocked by cassava residue. They are features with high starch extraction rate and good screening effect.

4. Desanding: After the separating section, the starch slurry still contains sand which need to be removed by desander machine. The function of desander in cassava starch making process is to fully remove the fine impurities in starch so as to ensure the taste and quality of starch.

5. Concentration and refiningStarch slurry refining is accomplished by hydrocyclone station, which is used for separation of fine slag, protein separation, washing, concentration and refining of starch slurry. This cassava starch processing machine has advantages of compact structure, high separation precision and good sealing effect.

6.Starch milk dewatering: Peeler centrifuge is a cassava starch processing machine which adopts continuous operation and intermittent discharging. It is mainly used for starch dewatering process which can effectively decrease moisture content to 36.5%. The contact part of this machine is stainless steel which prevent cassava from pollution.


Flash dryer 

7. Starch drying and packing process
Drying is carried out after the dehydrating process in cassava starch making process. Flash dryer is the widely used cassava starch drying machine which features with high heat exchange rate and short drying time. The water content of starch product is about 13.5% through drying. Then the collected starch is packed for warehousing.

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

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.
