Globally, countries and regions suitable for purchasing cassava pellet machines, carrying out cassava pellet production lines and cassava pellet processing businesses include:

1. South America

Cassava is native to South America and is most commonly grown in the region. South American countries such as Brazil, Colombia, and Venezuela are all important producers of cassava.

2.Africa

In Africa, cassava is one of the main food crops in many countries. The growing area of cassava in Africa is about 38,000 square kilometers, mainly distributed in Nigeria, Congo, Congo (DRC), Tanzania, Ghana, Angola, Cote d’Ivoire, Malawi, Mozambique and other places.

3.Asia

In Asia, cassava cultivation is mainly distributed in countries and regions such as China, India, Thailand, and Indonesia. Especially the southern coastal areas of China and Yunnan Province are the main growing areas of cassava.

4. Central America and the Caribbean

In Central America and the Caribbean, cassava is grown in Panama, Mexico, Cuba and other countries.

Cassava has been widely used as an energy source in pig diets in many developed and developing countries. Nigeria and Brazil produce the largest amounts of cassava and use it in the greatest quantities as livestock feed.

Thailand is the world’s largest cassava exporter. The country’s annual cassava output is 16 to 20 million tons (fresh weight), 60 to 70% of which is processed and exported. Europe uses 17∙5% of the world’s total cassava production as animal feed (cassava pellets)A large portion of this comes from Thailand and other Asian countries.

When there is demand, there is market. The applications of cassava are unlimited, and the prospects of cassava pellets are also unlimited.

In the processing of cassava pellet feed, not only fresh cassava can be used as feed raw materials, but also various by-products such as cassava leaves, cassava peels, and cassava residues. Through further processing, a variety of cassava feed products with different nutritional values can be obtained.

The following are the nutritional contents of cassava processing by-products and their stems and leaves:

Nutrition and name	cassava residue	cassava stem	cassava leaves	cassava distiller’s grains
dry matter	17.3	89-90	91-92	80.2
crude protein	2.0（干）	21	17-18	14.3
Fat	2.0	6-7	5-6	3.59
crude fiber	18.5-25.0	20-24	17-18	23.0
Ash content	11.7	8-10	9-10	9.04
calcium	0.55	1.0-1.4	1.75	0.53
phosphorus	0.46	0.25-0.28	0.32	0.13

1.Fresh cassava root (cassava root) or cassava tuber (cassava tuber)

The moisture content of cassava roots or cassava tubers exceeds 60% and will deteriorate within 2-3 days. In order to facilitate storage and transportation, the moisture content needs to be reduced to less than 14% as soon as possible.

Dried cassava can be obtained by washing the fresh cassava roots with sediment, peeling or peeling them, cutting them into thin slices by machine, and exposing them to the sun on a cement floor for 2 to 3 days until the moisture content is reduced to less than 14%.

Crush dried cassava to obtain cassava root meal (cassava root meal), also referred to as cassava root meal (cassava root meal). The main component of dried cassava is starch, and the starch content of peeled sweet dried cassava is 81% to 88%.

Dried cassava is the most basic cassava processed product and is produced in large quantities in Thailand, Malaysia, Indonesia and Africa.

2. Cassava peel

The starch content of cassava peel is only 16%, the content of crude ash and crude fiber is high, and the content of crude protein is low. The cyanide content in cassava peel is much higher than that in cassava pulp, making it suitable for animal roughage.

3. Cassava residue pulp

Cassava residue is a by-product of cassava processing for starch or ethanol. If the crude protein content is not taken into consideration, referring to the American roughage quality evaluation index [Relative Feed Value (RFV)], cassava starch residue belongs to the special-grade roughage, while cassava alcohol residue belongs to the fifth-grade roughage.

The moisture content of fresh cassava starch residue is as high as 60% to 70%, and physical sedimentation or pressing methods are usually used to reduce the moisture content.

4. Cassava leaves

Cassava leaves are a by-product after harvesting cassava roots, accounting for 10% to 40% of the weight of the above-ground parts of the plant.

The dry matter content of fresh cassava leaves is 20% to 30%, and the crude protein content of dried cassava leaves is 15% to 30%. The amino acid content of cassava leaves is similar to that of alfalfa, making it a good protein feed.

Recycling and utilizing cassava residue is a necessary condition for alcohol plants to reduce production costs and improve competitiveness. Therefore, it is highly recommended that your company develop cassava residue fermented feed. While solving the problem of cassava residue disposal, it turns waste into treasure and becomes a feed product that can produce more objective economic benefits.

Here, we provide you with an example of our cassava residue fermented feed pellet production line project in China for reference:

1. Process design

The cassava pellets production project plan is designed based on the fermented feed process requirements. Basic process flow:

• Fermentation raw materials such as cassava residue are first mixed and proportioned through the ingredient mixing system, and the moisture content after mixing is controlled at 60%;
• Then it is transported to the aerobic fermentation system for biological fermentation and degradation in a closed aerobic fermentation tank. The temperature is controlled at 37°C. The fermentation cycle is 2 days according to the product requirements. After fermentation, the moisture is controlled at 40% and connected to an anaerobic bag.

This project uses a cassava pellet making machine plant with a daily production capacity of 10t/h cassava residue fermented feed pellets, and the feed pellet mill used is SZLH250. The final pellet feed product of this cassava pellet machine line has a total acid content of 10% and a microbial colony population of 1.0*109CFU/g.

(1) Ingredient mixing system

According to the moisture content and crude fiber content of cassava residue from the customer of this project.

According to the requirements of aerobic fermentation moisture, carbon-nitrogen ratio, pH and other fermentation conditions, as well as product nutritional goals, a certain proportion of soybean meal, bran and microbial fermentation agents are added to the cassava residue to adjust the carbon-nitrogen ratio, nutrients, particle size and pores of the material. rate, moisture, etc., in order to promote fermentation and improve fermentation quality.

• For cassava residue with a moisture content of about 70%, the shaftless screw conveyor technology equipment is used to solve the problems of leakage, sticking and blockage in conveying high-humidity and viscous materials;
• Soybean meal and bran adopt batching bin storage, bucket lifting, and spiral discharge and conveying technologies. The technology is mature and the equipment is reliable. A mechanical arch breaking mechanism is set up for the batching bin, which solves the problem of arching when unloading materials with small specific gravity. ;
• A liquid adding device is set up according to the fermentation needs, which can not only adjust the fermentation water, but also add fermentation bacteria as needed.
• All fermentation raw materials are proportioned through computer control, and then transported to a solid-liquid continuous mixer suitable for high-humidity and viscous materials for mixing. After stirring evenly, they are transported to the next link.

(2) Aerobic fermentation system

The design adopts closed aerobic fermentation reaction technology. The entire fermentation process is completed in the reactor. It has a compact structure, small footprint, high degree of automation, energy saving and environmental protection. The reactor consists of a tank, transmission system, stirring system, aeration system, unloading system, exhaust gas centralized treatment system and control system.

The moisture content of the stirred fermentation raw materials is 60%. The bucket elevator is designed to transport the high-humidity materials to the aerobic fermentation reactor. After regular stirring and aeration, biological fermentation is carried out internally.

The fermented materials are transported from the bottom It is discharged from the discharge port and output through the screw conveyor, realizing harmless treatment and resource utilization.

(3) Fermentation equipment

• Using single-chip microcomputer control, continuous batching and metering, high production efficiency; equipped with a liquid addition system, which can add fermentation bacteria and trace elements, etc., making the production process more flexible.
• Aerobic fermentation system: Using closed aerobic fermentation process equipment, through reasonable design and regulation of temperature, oxygen and other parameters, the efficiency of factory production of cassava residue treatment can be achieved, with a high degree of automation, a small footprint, and no exhaust gas The treatment effect is good, the project investment is reduced, and the operating cost is reduced.

2. Economic benefit analysis

The comprehensive cost of the cassava residue pellet feed products produced by this project is around 2,000 RMB, which will have a certain price advantage and considerable profit margins. Based on the customer’s current production scale, which produces 10 tons of cassava residue fermented pellet feed every day, and based on 330 working days per year, its annual output will reach 3,300 tons.

Based on the annual production of 3,300 tons of cassava fermented pellet feed and the selling price of each ton of feed at 2,500 RMB, the new annual output value will reach 8.25 million RMB and the net profit will be 1.65 million RMB.

If this customer puts all the cassava residue obtained from ethanol production into the production of cassava residue pellet feed (based on the production of 0.35 tons of cassava residue per ton of alcohol and an annual output of 150,000 tons of alcohol, the annual output of cassava residue is 52,500 tons), it will create an annual economic benefit of 1.3125 billion, and the net profit will reach 26.25 million RMB.

It can be seen that for this Chinese customer, the fermentation of cassava residue to produce feed products will also open up a new sustainable development direction for the customer company, which is of great significance to the non-grain feed resources that are increasingly valued.

In some places, cassava is fed directly to animals, but this is becoming increasingly rare as more and more feed processors adopt the cassava pelleting process. The reason why pelleting has become the mainstream process in the feed industry has been verified countless times.

In actual production applications, there are three main processing methods for the application of cassava in livestock and poultry feed, and their utilization methods are as follows:

1.Direct application

This method is to add fresh cassava residue directly to energy protein feed to make compound feed. However, fresh cassava residue has a high moisture content, about 70% to 80%, and is not suitable for storage, especially in summer. It may go bad in a very short period of time.

Such cassava residue will be harmful to animals. Cause very serious consequences. Not only that, fresh cassava residue has a high crude fiber content, poor taste and is not easy to digest, which can easily lead to low feed intake of livestock and poultry, or even refusal to eat in severe cases.

2. Drying and granulation – using cassava pellet making machine

This method is to dry the cassava residue into particles through a certain processing method and then use it as energy feed or roughage. Although this greatly reduced the moisture content in the cassava residue and solved the problem that the cassava residue was not suitable for storage, it still failed to solve the problem of high crude fiber content and good palatability of the cassava residue.

3. Biological fermentation – using cassava pellet making machine

The difference between this method and the second method lies in the fermentation process, but both include a granulation process.

This method is to add microorganisms to cassava residue to make fermented feed. The physical and chemical properties of the cassava residue treated in this way will change, and the crude fiber contained in it can also be degraded into small molecular substances such as monosaccharides, disaccharides, and amino acids that are easily digested and absorbed by animals, thereby improving the digestion of the feed. The rate has increased.

At the same time, during the processing of cassava residue, a large amount of nutritious microbial proteins and other useful metabolites may be produced and accumulated, such as organic acids, alcohols, aldehydes, esters, vitamins, trace elements, etc.

These substances can It makes the feed softer and fragrant, and a variety of digestive enzymes and growth-promoting factors can enhance the animal’s disease resistance and promote the growth and development of the animal. Some metabolites can even extend the shelf life of the feed and play a preservative role in the feed.

At present, the second and third methods are mainly used in cassava pellet feed processing. If you want to know more about the cassava pellet processing technology, contact us to get the best cassava pellet machine system plan and quotation.

The following points should be noted when using cassava residue as feed:

1. Problems with sealing and preservation of cassava residue. Fresh cassava residue has high moisture content and is prone to mold and deterioration. It should be sealed and stored in time to avoid deterioration and animal poisoning.
2. Nutritional balance of feed. Since cassava residue has the disadvantage of unbalanced amino acid composition, high-quality protein feed or synthetic lysine and methionine should be added during processing to balance the feed amino acids.
3. Problems with feed amount and feeding time. Due to the high content of fibrous substances and cyanogenic glycosides in cassava residue, the feeding amount needs to be strictly controlled to avoid causing hydrocyanic acid poisoning. At the same time, cassava residue is not suitable for feeding young animals and the feeding time needs to be controlled.

As a result, the use of cassava in feed in the Philippines has been steadily increasing in recent years, partly because of the gradual shortage of corn, a traditional dietary energy source, and to a large extent due to the price advantage of cassava Caused by.

In the Philippines, the commercial production of cassava flour has a long history in production and utilization, and it has been possible to provide cassava as a relatively cheap commercial feed to the livestock industry. Some commercial pig farms have also used cassava flour and cassava pellets in grow-finishing and lactation feeds.

For the obvious reason of increasing livestock and poultry production costs the Philippines recognizes the need and opportunity to support the commercial production of cassava as livestock feed. Here are some considerations:

1. Increased use of cassava in animal feed: The livestock and poultry breeding industry in the Philippines is developing rapidly, but the supply of corn is insufficient and the price is high, which shows that there is a good prospect for increasing the use of cassava in feed. It is estimated that by the end of 2030, the portion of total cassava production used as animal feed will increase from 5-20% last year to 50-90%.
2. Improvement of technology: The Philippine Root Crops Research and Training Center and its collaborating institutions have been conducting research on root crops. It is unanimously agreed that there is now a large amount of technology and information that is enough to push the production of root crops to a higher level. These technologies include the improvement of varieties, the application of modern equipment and processing machinery, and the development of sales channels.
3. The area of prime farmland continues to shrink: An average of about 8,000 hectares of prime farmland are converted to other uses every year, which will encourage people to use areas of poorer quality. Root crops are relatively tolerant of adverse agricultural climates and therefore have an absolute advantage in such conditions.

In the Philippines, a stable market for cassava as livestock and poultry feed can promote its production. The Philippines is capable of producing commercial quantities of cassava, but it needs assurances of sales.

• After the financial crisis broke out in Thailand in 1997, the proportion of cassava added to Thai pig feed began to increase significantly. High-quality cassava chips can completely replace broken rice or corn in the diet of growing and finishing pigs. The recommended dosage of cassava in Thai pig diets is: 10%-20% for suckling piglets; 20%-40% for growing pigs; 40%-80% for fattening pigs; and 60% for sows.
• The dosage of cassava in the Philippines is slightly conservative. In the diet of growing and finishing pigs, 20%-40% is the commonly used amount of dried cassava and has been proven to be a safe addition.
• In Vietnam, dried cassava is commonly used in pigs, with a large proportion (50%-70%) added to the diet of growing pigs. When supplemented with 10% casein, the added amount can reach more than 80%.
• In China, based on the practical experience of people in various places, the recommended dosage of cassava in pig diets is: small pigs (20-35kg), 40%; medium pigs (35-60kg), 40%; large pigs (60-90kg) , 45%, but all recommend supplementing multivitamins and methionine.

In addition, in terms of growth performance and economic benefits, cassava can replace 55% of corn in domestic goose diets. Cassava can completely replace corn in ruminant concentrates and aquatic feeds without adverse effects.

Poultry type	Content(%)
Broilers	25-30
Layers	40-45
Duck	40-50

In Thailand poultry diets, cassava can completely replace corn, but its content in the diet does not exceed 50%.

1. First of all, cassava alcohol residue is the waste leftover from cassava in the process of producing alcohol. There is a large output every year. If it is discarded directly, it will not only waste resources but also pollute the environment. Using cassava alcohol residue as feed raw material can also alleviate the problem of feed shortage, reduce feed costs, improve breeding efficiency, and can also bring positive economic benefits to farmers and feed companies.
2. Secondly, the nutritional value of cassava alcohol residue is not as high as that of conventional feed, and it requires later processing, but the processing method is immature and not very popular. After processing and fermentation, the nutritional value has improved, but there are still some problems with the amino acid balance, and synthetic amino acids need to be added.
3. Third, as a new feed resource, cassava alcohol residue can be valued. it needs the support of national policies and attaches great importance to the development of specialty agriculture.
   Due to the shortage of other conventional feed resources in the market, the intervention of new feed raw materials is needed to alleviate. As society with the advancement of science and technology, the feed production and processing technology is also constantly improving.
   Cassava alcohol residue is mainly grown in tropical and subtropical areas, so it has a certain locality, and transportation costs must be considered in non-tropical areas. In addition, as a new feed resource, consumers have low trust in it, so some effort is needed in the promotion of new raw materials in this aspect.
