Cassava processing and storage

The processing direction of cassava processing and storage is mainly cassava starch, cassava flour, dried cassava and garri. The main uses of cassava are in food, feed and industrial development. Cassava is one of the main starch raw materials in the industry. Cassava is not only rich in starch, but also rich in edible fiber, amino acids, vitamins, trace elements and mineral elements. It is a natural and safe miscellaneous grain and is a good quality grain raw material. However, due to the seasonality of cassava harvest, perishable deterioration, inconvenient storage and transportation, etc., cassava must be treated as soon as possible after harvest.

Cassava starch is a product of washing, screening, crushing, filtering, dehydrating and drying of cassava, which can be further processed into alcohol, syrup. Cassava flour is made by washing, pulverizing, dehydrating and drying cassava, compared with starch processing, cassava flour processing is easier. Cassava chips are divided into white cassava chips and brown cassava slices with skin. The processing of white cassava chips is fine. The uses of these two types cassava chips is also different. Garri is a kind of daily diet which is made by peeling and crushing cassava, dehydrating and frying after fermentation. By the way, Doing Company provides a variety of cassava processing machines. In Africa, with an annual output of more than 100 million tons of roots, except for Nigeria and South Africa, there is almost no starch extraction industry, and the introduction of machines is the only way to increase the economic value of cassava.

The main nutrients of cassava are starch and dietary fiber, dried cassava powder can be used in cooking and food production. Generally, after the dry cassava is powdered, there is no toxin, so there is no need to do detoxification before and after powdering. 65% of the world's total cassava production is used for human food and is one of the main food crops in African countries. As a raw material for the production of feed, cassava meal and leaves are a high-energy feed ingredient.

Now, in addition to the development direction of cassava food consumption, cassava energy structure will also be an important development direction. Cassava starch can be further processed into modified starch for a wider range of applications. About cassava processing and storage, in the fermentation industry, cassava starch or dried tablets can be used to make alcohol, citric acid, glutamic acid, lysine, cassava protein, glucose, fructose, etc. These products are used in food, beverage, medicine, textile (dyed cloth), paper making, etc. Both have important uses.

There are two main methods for fresh cassava storage: open-air stacking and trenching:

Open-air stacking method: choose a truss damp place, bundle the bundles of cassava stalks, and regularly erect (or laterally) stack the stalks on the top to cover the straw or weeds and finally cover the film. When stacking cassava stems in the open air, the amount should not be too large. Pay attention to proper ventilation to avoid suffocation at high temperature.

Trenching method: that is, shallow ditch storage method is to choose a place with leeward sun and good drainage, dug into a ditch (1.5-2.5 m wide and 0.5-1 m deep), and cut the chopped cassava stems into the ditch longitudinally. Inside. The middle stack is slightly higher, the sides are convex, leaving 3-5 vents, covered with straw, and finally covered with 4-5 inches of soil.
