Industrial cassava starch processing machine making plant

Cassava starch is produced from fresh cassava roots by wet-milling method. The whole cassava starch processing machine is comprised of six major sections: washing & cleaning equipment, cutting and crushing equipment, separating equipment, concentrating and refining equipment, dehydrating equipment and drying equipment.
Cassava starch processing machine 

1. Cleaning and washing machine: The purpose of cleaning and washing is to wash raw cassava roots thorough multiple stage cleaning and washing process so as to fully wash the dirt, soil, sand and other skin sediment. Thus it can improve the purity of the raw material, and facilitate the next process in cassava starch production line. And the widely used cassava starch processing machine for this section is dry sieve and paddle washing machine. The main features of these machine are low water and power consumption, large capacity and easy handling.

2. Grinding machine: The cassava root need to be grinded into slurry in order to release its starch from cell wall. Rasper is the cassava starch processing machine used for this purpose. The grinding rate determines the extraction rate of cassava, therefore it is important to choose a high efficient grinding machine for cassava starch processing plant. DOING rasper introduces the advanced international technology which can achieve a high grinding rate and high starch extraction rate.

3. Screening machine: To separate and purify starch by screening in cassava starch processing plant. At present, centrifuge sieve is mainly used cassava starch processing machine to remove fine slag. Multiple screening or counterflow washing process is generally adopted. It is required  that, through screening and washing of the original pulp, the starch content of cassava residue is less than 35%, the free starch content is less than 5%, and the content of fiber impurities in the pulp is lower than 0.05%.

4.Concentrating and refining machine: After separating, the starch slurry still need to be concentrated and refined. In cassava starch manufacturing process, the mainly used cassava starch processing machine is hydrocyclone station. The main function of hydrocyclone is to remove the fine fiber, protein and cell sap out of starch slurry to make the final starch meet the standard.

5. Dewatering machine: The dewatering process is maily for reducing water content of cassava milk so that it can meet the drying standard. The cassava starch processing machine used for starch dewatering is peeler centrifuge. This is required that the water content of cassava starch is about 38%-40%.

6. Drying machine: The starch is sent to flash dryer with screw conveyor for drying steps. Negative pressure method is adopted by this cassava starch processing machine, thus ensuring the quality and moisture uniformity of starch.  The required moisture content after drying is about 14%.

7. Sifting and packing machine: In order to make sure the uniformity of starch granule, starch need to enter the vibration sieve for sifting after air cooling. The sifted starch by cassava starch processing machine is then packed by semi-automatic packing machine and weighted for storage.  It is required to keep the warehouse ventilated and take fire precautions.

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.
