[ Food Machinery and Equipment Network Policies and Regulations ] Recently, the "Feed Raw Material Potato Protein Powder", which was formulated by the China Starch Industry Association and jointly prepared by the China Starch Industry Association and China Light Industry Cleaner Production Center, was approved for release. As the name suggests, potato protein powder is extracted from potatoes. Today, with the advancement of the potato staple food strategy, potato protein powder is being continuously developed and utilized. The market penetration rate of related potato protein powder production lines will also increase.

It is understood that potato protein powder has a high nutritional value and is rich in protein. The crude protein content of plant protein reached about 75%, and the nitrogen-free extract was about 13%. In addition, the protein content of potato protein powder is balanced, comparable to skim milk powder and fish meal, and the apparent or true digestibility of amino acids is also similar to that of soybean meal.
Today, the release of "Feed Ingredients Potato Protein Powder" will bring standardized process management to the production of potato protein powder, and promote the standardized and large-scale production of potato protein powder. At the same time, this will also bring a market increase for potato protein powder production equipment.
The production process of potato protein powder includes defoaming, acid adjustment, heating, flocculation, centrifugal extraction, flash drying, and filling. At present, the equipment used in the production of potato protein powder mainly includes defoaming equipment, acid adjustment equipment, plate heat exchangers , centrifugal equipment, flash dryers , packaging machines and the like. With the development of production technology, the production capacity of potato protein powder production line is also continuously improved, and the processing performance has become increasingly stable.
At present, China's support for the potato deep processing industry has also caused many potato growers to start from single sales to deep processing, bringing benefits to related production equipment. A potato industry company in Shangdu County, Inner Mongolia has introduced an advanced potato waste-free refined starch processing production line in the past two years, and built an integrated system of potato fine fiber and protein powder extraction, forming an annual processing of 120,000 tons of potatoes and production of 20,000 refined starch Multi-ton, fine fiber and protein powder each have more than 2,000 tons of processing production capacity, extending the potato processing chain and improving potato processing efficiency.
Dingxi City, located in Gansu Province, has also been vigorously developing potato deep processing in recent years, using the production of potato protein powder and other products to increase comprehensive industrial benefits, helping farmers to increase industrial income and get rid of poverty. Last year, a local potato planting and processing company invested 76 million yuan to add one potato refined starch production line with an annual output of 80,000 tons and four potato protein powder extraction production lines with an annual output of 10,000 tons. The potato starch produced accounted for 10% of the national market share. %.
But it is worth mentioning that the energy saving and environmental protection of potato protein powder production line still needs to be further enhanced. At present, the wastewater of most potato processing enterprises is simply discharged into rivers, fields or open areas after simple treatment, causing serious environmental pollution. At present, environmental protection awareness is gradually gaining popularity, especially the implementation of the new environmental protection law, which has caused many potato processing enterprises to face the predicament of suspending business for rectification.
This requires relevant equipment manufacturers to further optimize the environmental performance of the equipment, reduce the discharge of wastewater and improve the utilization rate of process wastewater. A company in Gansu Province installed a process water extraction device on the newly-built potato protein powder production line, which can process 700 tons of starch process water per day, extract about 5 tons of light yellow food-grade protein powder, and recover a mixture of fine fiber and small particle starch About 5 tons, not only reduces the concentration of process wastewater, but also brings rich profits for starch enterprises.
At present, China's potato deep-processing projects continue to advance, and standard documents such as "feed material potato protein powder" have also been gradually released. In this environment, China's potato protein powder market will also usher in a rapid development stage. At the same time, the potato protein powder production equipment market must be further upgraded and optimized for environmental performance while increasing.
