Double benefit of "treasure digging" extract from sweet potato

Sweet potato is a common food on the table The price per kilogram is only two or three yuan Recently, a sweet potato extract production line was put into operation in shangcang Industrial Park of Jixian County This production line can not only produce sweet potato powder, but also extract sweet potato fibrin Through deep processing, the value of sweet potato will be doubled In the workshop of Tianjin Huanhu agricultural science and Technology Co., Ltd in shangcang Industrial Park, the sweet potato deep processing production line is undergoing commissioning and operation, which processes up to 25 tons of sweet potato per hour Among them, it is one of the core technologies of the company to reuse the nutrient water produced by crushing and beating sweet potato Xu Xiaojing, deputy general manager of production of Tianjin Huanhu agricultural science and Technology Co., Ltd., said: "the starch pulp of sweet potato after cleaning, grinding and separation is transported to that side for drying to make starch products Here is the cell fluid part, another part of our extract, which will be piped to the extraction workshop of our water recycling treatment " The extract workshop in the water recycling system is the core workshop of the company, where all the nutrients except starch in sweet potato will be extracted Sweet potato fibrin powder is a by-product in the production process of sweet potato starch Brewing and drinking can meet people's intake of dietary fiber, but also retain the ingredients in sweet potato that are beneficial to lose weight and moisten the intestines The market price is three to four times that of starch Li Jianxue, general manager of Tianjin Huanhu Agricultural Technology Co., Ltd., said: "this year, the price of sweet potato starch is about 8000 yuan per ton, and the market price of sweet potato extract is about 36000 yuan per ton." "Sweet potato cleaning needs a lot of water, and the water contains sediment In the process of starch washing, there is a lot of nutrient water rich in protein This kind of water microorganism has a very fast fermentation time and strong sour taste, so it needs a lot of human, material and financial resources to deal with this sewage," Li Jianxue said At present, Tianjin Huanhu agricultural science and Technology Co., Ltd has invested more than 40 million yuan to optimize and upgrade the production equipment, treat the sewage generated by cleaning and crushing sweet potato respectively, independently develop and design the water recycling and reuse system and relevant production technology The traditional starch processing takes days and months, but it only takes 15 minutes here The sweet potato noodle production line just completed by the company has greatly improved the production efficiency and further improved the quality of sweet potato noodle Li Jianxue said: "the traditional process of homogenizing and pulverizing needs a process of freezing and airing It takes about 48 hours from the time of powder feeding to the appearance of the powder strips We only need three hours from feeding to discharging, and the core technology is that we don't need to add any auxiliary additives to realize the production, product tumbling and boiling resistance of the vermicelli " At the same time, Tianjin Huanhu agricultural science and Technology Co., Ltd actively connects with farmers to promote their income Li Jianxue said: "the planning is to take the road of integration of the first, second and third industries Our enterprise acts as a platform for production, processing and sales, connecting people and consumers at one end We buy sweet potatoes from the hands of ordinary people and cooperatives to ensure the planting income of ordinary people The cooperative or farmer that cooperates with us, we can feed the profits of starch and vermicelli back to the common people, and the profits of our enterprise are obtained from the sweet potato extract, and use technology to help the enterprise develop and make money "
