The preparation method of edible cassava starch

-

Edible cassava starch is produced from fresh cassava roots. The preparation method and process are cassava cleaning, washing, cutting, crushing, fiber separating, de-sanding, protein and cell liquids, dehydrating, drying, and sieving. The article will have a detailed introduction to the preparation method of edible cassava starch.

The preparation method of edible cassava starch can be divided into three parts: raw cassava cleaning, starch extraction, and drying.

Raw cassava cleaning

Cassava tubers attach lots of impurities after harvesting from farm fields. Therefore, cleaning cassava is required before preparing edible cassava starch. The Dry sieve machine and paddle washer are used in the cleaning section. The dry sieve will first remove impurities attached to the surface of cassava roots, and then the paddle washer machine will clean the cassava thoroughly.

Cassava starch extraction

This is the key part of the preparation method of edible cassava starch, which will influence starch yield and starch quality. After cassava is cleaned well, the next is the cutting and crushing process, releasing starch as much as possible. The rasper machine is used for crushing purposes, it is the key equipment to ensuring a high starch extraction rate.

After crushing, what we get is cassava mash. Cassava mash will first be pumped into a centrifuge sieve machine to separate fibers, and then cassava slurry will go through a de-sander machine to eliminate tiny sands after the slurry is pumped into a hydrocyclone station. The hydrocyclone station is used to separate protein and cell liquids, getting purified cassava starch milk output. The 18-stage hydrocyclone station is applied here to ensure high cassava starch quality and high starch yield.

We can get purified and concentrated starch milk from hydrocyclone. The next process is to dehydrate and dry it. To ensure a better dehydration effect, a peeler centrifuge is used here, from which we can get wet cassava starch with a moisture content of around 38%. After that, the wet starch powder will be transported into the flash dryer, and finally, we can get dried cassava starch. To ensure high quality starch, a sieving machine is installed after the flash dryer.

The above is an introduction to the preparation method of edible cassava starch. As a professional manufacturer, Henan Jinrui can supply complete machines for cassava starch production. If you have such a plan to set up a cassava starch factory, feel free to contact us any time.

  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 cassava meal processing machines in Nigeria

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.
