It is a well-known fact that effective use of the active ingredients in potatoes is a fact that the production of potato starch which only extracts starch has caused some negative effects on the environment. Unfortunately, so far, for most potato starch producers, the extraction of starch remains their only goal. This means that other valuable ingredients in the potato have not been developed. These ingredients include: protein, fiber, salt, minerals, and even water. If these useful ingredients in the potato are not extracted, they can only be discharged with the waste water. At this time, the potato starch processing enterprises not only wasted effective resources, but also caused serious pollution to the environment. As more and more countries have strict requirements on environmental protection, the discharge of sewage from potato starch processing companies must be solved.
When potato starch manufacturers have to solve the problem of sewage discharge, they usually adopt the method of constructing a sewage treatment plant with huge investment and complicated process while building a potato starch processing plant. However, the sewage treatment plant only increased the investment of the company and did not contribute to the economic benefits (or profits) of the starch company.
Is there any way to effectively use all the active ingredients in the potato and solve environmental problems? The Dutch “Non-waste Potato Starch Factory†successfully built in the United States by the Dutch company Nivoba has already answered this question.
Latest potato starch processing technology Starch is the main product of potato starch processing. By using the Dutch company's starch production technology and equipment, 95% of the starch contained in potatoes can be extracted to make commercial starch. The characteristics of the process and its corresponding equipment are: low consumption of processed clean water, low energy consumption, and the use of a waste streamer to complete the concentration and refining process has many advantages over the use of a centrifuge. The equipment maintenance cost is low and it is easy to install (plate type Structure, factory debugging, and excellent design and manufacture of MCC and OCC.
Using this equipment, 1 ton of potatoes can produce 208 kg of refined starch (commercial starch with 18% moisture content). Potato contains about 13% of fiber. Potato fiber is extracted as a by-product from starch production. In the “extraction unit†of potato starch production, the fibers are separated from the final cone screen. The separated fibers were dewatered using another cone sieve. The dehydrated fibers contained 1% of coupled starch and 88% to 89% of moisture. Potato fiber can be sold to farmers for animal feed. One ton of potato can produce 209 kilograms of wet fiber (11% of dry matter).
The average potato contains 2.8% protein. Protein powder is the most valuable byproduct of potato starch processing. At some modern potato starch plants, protein extraction from potato juice has become an integral part of starch production. Proteins in potato can only be extracted after flocculation. Potato proteins that flocculate and become solid can be separated by solid-liquid separation. The traditional separation method is to use a multi-stage horizontal screw separator to separate proteins. This method has the limitation of large investment and low recovery rate.
Nivuba's protein extraction is performed in the juice water discharged from the concentration unit. The separation of flocculating protein from juice water is accomplished through a special vacuum drum filter. This "special vacuum drum filter" features "non-woven" materials (different materials) to assist protein separation and dehydration. The facts have shown that its advantages are: the recovery of protein from the juice of potato juice, compared with the traditional use of a horizontal spiral centrifuge, the protein recovery rate of 5% to 10%. This means that companies using this “special vacuum drum filter†to separate protein from the juice of potato juice will have greater economic benefits. At the same time, the burden on the environment is greatly reduced.
In fact, due to the use of animal protein as a feed to cause "mad cow disease" and other reasons, many countries no longer use animal protein as an animal feed additive, so plant proteins are used by more and more countries, therefore, potato starch factory protein recovery The economic benefits will become more and more significant in the future. Through the use of the technology and equipment of the Nivuba Protein Recovery System, 1 ton of potatoes can produce approximately 15 kilograms of protein. (dry matter content 90%)
The average potato contains 76% of water. In addition to starch, protein and fiber, the potato itself is also rich in water, salt, minerals, etc. After the concentration stage of starch production, the protein contained in the potato juice water has been separated from the above processing. After the protein is extracted, the water from the “Special Vacuum Drum Filter†is still rich in nutrients such as salt, minerals, etc. (soluble solid content is 2.5%).
In order to increase the concentration of the solid material and extract the water therein, the filtered water was evaporated using a vacuum evaporator. Due to the vacuum evaporation system, the energy required for evaporation is extremely limited. After evaporation, the concentration of soluble solids (mainly organic matter) is approximately 40% and can be directly applied as fertilizer.
With the Nievaba evaporation system, 1 ton of potatoes can produce 200 kg of fertilizer. The evaporated water is condensed by an active filter to remove a small amount of esters contained in the water. The water from which the esters have been removed is used directly in the processing of the starch, so that the fresh water used for starch processing is extremely limited.
After processing the above mentioned equipment and technology, 1 ton of potatoes can produce 366 kg of water during the production of starch. It is understood that this waste processing potato starch processing technology and equipment of the Netherlands Niwaba has been successfully used in a modern potato starch factory in Myanmar, United States.
Although the environmental protection laws of the United States, Myanmar, are particularly strict, after the above systems were used, the production of the project was approved by the environmental protection department in the absence of other sewage treatment facilities.
Through the use of the latest potato starch processing technology and equipment, the products that can be produced from potatoes through complex processing include: potato starch, potato protein powder, potato fiber, spray fertilizer, and processed water, that is, 100% utilized. Various active ingredients contained in potatoes. The implementation of this potato starch processing technology and equipment does not have any negative impact on the environment while fully utilizing the useful ingredients of the potato, and completely solves the environmental pollution problem of the potato starch factory.
