The Wet Extraction Method for Cassava Starch

-

Cassava starch is an important raw material widely used in food and industrial fields. The wet extraction method for cassava starch is an advanced way to quickly and efficiently extract pure starch from cassava tubers, which ensures a high yield and superior quality of starch, making it a preferred choice for starch producers. This article will introduce the wet extraction method for cassava starch to you in order to give you some guidance for starch processing.

According to the wet extraction method for cassava starch, its processing technology can be roughly divided into three important stages: the cleaning stage, the processing stage, and the drying stage.

The cleaning stage under the wet extraction method for cassava starch refers to the preliminary processing, that is to say, it is to remove the impurities attached to cassava tubers in the picking process. Fresh cassava tubers firstly will enter a dry sieve to sieve off the weeds and stones and so on, then they will be conveyed to a paddle washing machine by a belt conveyor. The paddle washing machine will remove the sediment with the counter-current water flow.

According to the wet extraction method for cassava starch, the processing stage is to transform the cassava tubers into cassava pulp, from which the starch will be finally extracted. The cleaned cassava tubers will be first cut into pieces in a cutting machine. Then the cut small cassava pieces will be converted into fine pulp by a cassava rasper machine under the grinding effect. The cassava pulp will be conveyed to a centrifuge sieve for separating cassava residues and pumped into a desander for removing the remaining mud and sand. Following this, the cassava slurry will enter a hydrocyclone station for further purification, washing, and refining. Finally, a peeler centrifuge will be configured to dehydrate the excess water for the next drying stage. This is the working flow of the processing stage!

Under the wet extraction method for cassava starch, the drying stage is to dry the wet cassava starch. The dewatered cassava starch slurry will be transferred to an airflow dryer, which with the negative pressure drying principle will reduce the moisture content by less than 14%. Finally, an automatic packing machine will help to pack the qualified starch, preventing moisture absorption and ensuring the starch quality.

The above is an introduction to the wet extraction method for cassava starch. If you want to set up a cassava starch processing factory or want to get more details about the starch processing technology, welcome to contact us!

  Cassava is a type of carbohydrate that we can often see. In addition to simple baking, it can be processed into starch and then made into various foods or beverages and other uses. Therefore, for the special cassava starch production line. Companies need to choose the right equipment for high quality cassava starch production. Specifically, the techniques for selecting a cassava starch production line processing facility include the following aspects: 1. Select production process and cassava starch production line according to economic strength and market requirements There are many processing technologies for cassava starch production line on the market, such as full-swirl process, small and medium-sized simple processes, small and simple processes. The easy-to-use cassava starch production line manufacturers introduce some of them for large-scale production and use, and the starch quality is very good, the processing cost is relatively higher, and some are suita

Locally made cassava meal processing machines in Nigeria mainly adopts two processing methods to assistant the production, the cassava meal dry process and wet process. Here is the comparison of the two methods. The procedures of cassava meal production with dry method: Locally made cassava meal processing machines in Nigeria, which adopts the dry processing method, has the procedures like that: fresh cassava roots cleaning and peeling, cutting or chipping, drying and milling. Alternatively, some opt to purchase dried cassava chips and use a single cassava milling machine to obtain cassava flour. Although locally made cassava flour machines are inexpensive, their quality and working speed are relatively low. As a result, they are only suitable for small-scale operations and yield poor-quality cassava flour. The procedures of cassava meal production with wet method: Locally made cassava meal processing machines in Nigeria use the wet processing method, which involves cleani

The main usage of cassava is food, animal feed, and industry processing and develop. [Read also: T he Cassava Processing Industry in Nigeria: Traditional Techniques, Technological Developments and New Opportunity ]  Cassava roots is one of the main raw material in the world for industrial starch production. Now, world harvested cassava, 65% used for food. As a raw material for the production of feed, rough cassava flour and leaves are a high-energy feed ingredient. In the fermentation industry, cassava starch or dried cassava chips can be used to make alcohol, citric acid, glutamic acid, lysine, cassava protein, glucose, fructose, etc. These products are widely used in food, beverage, medicine, textile (dyed cloth), paper making, etc. So as the question what are the end product of cassava, there don't have definite answer.
