Problems solved by technology

However, during the production of green (pea) bean starch, the most nutritious and economically valuable protein and fiber resources in green (pea) bean are wasted. At present, although some manufacturers have recovered protein from pulp water, they are limited by technology and equipment. , low recovery rate and poor quality, mainly used as feed, and the bean dregs rich in dietary fiber are also simply dried and used as feed additives, which greatly wastes resources

Embodiment 1

[0035] A method for separating and extracting fiber from starch-containing beans. The starch-containing beans of mung beans, peas, broad beans, cowpeas, kidney beans, and red beans are used as raw materials, and the raw beans after removal of impurities are heated to 50-90°C. Keep warm for 1-4 hours to reduce the moisture content of the beans to about 10%. In this example, peas are used, heated to 50°C, and kept warm for 1 hour. The heated peas are peeled by a peeling machine and pulverized with a needle mill. , the fineness of bean shells after crushing is more than 120 mesh, so that the fine powder after fine grinding is composed of bean shell powder with a particle size of 100-400 mesh, and the fine bean shell powder is gravity screened with a sorting and screening machine, according to the starch Granules and fiber particles are different in size. The 300-1250 mesh screen in the sorting and screening machine, the fiber particles can remain on the screen and be separated int...

Embodiment 2

[0037] A method for separating and extracting fiber from starch-containing beans, which uses mung beans, peas, broad beans, cowpeas, kidney beans, and red beans as raw materials. In this embodiment, mung beans are used to heat the mung beans after removal of impurities. To 60 ℃, keep warm for 1 hour, so that the water content of mung beans is reduced to about 10%, peel the heated mung beans through a peeling machine, grind them with a needle mill, and grind the bean shells to a fineness of 100-140 mesh Coarse bean hull powder is composed of 80 mesh-200 mesh sieves in a sorting and screening machine, and the fiber powder particles are sieved through the sieve to obtain coarse fiber powder particles; the concentration is 10-50% CaoH solution soaked for decolorization, and then Use a scraper centrifuge for dehydration. After dehydration, the water content is 35%-42%. Then use an airflow dryer to dry the fiber into a dry powder with a moisture content of less than 14%. After coolin...

Embodiment 3

[0039] A method for separating and extracting fiber from starch-containing beans, which uses mung beans, peas, broad beans, cowpeas, kidney beans, and red beans as raw materials. Red beans are used in this embodiment, and the red beans after removal of impurities are heated To 60 ℃, keep warm for 1 hour, so that the moisture of red beans is reduced to about 10%, peel the red beans after heating through a peeling machine, grind them with a needle mill type mill, and the fineness of bean shells is more than 120 mesh after crushing, so The fine powder after fine grinding is composed of soybean shell powder with a particle size of 100-400 mesh. The fine soybean shell powder is screened by gravity with a sorting and screening machine. Mesh-1250 mesh sieve, fiber particles can remain on the mesh sieve, separated into a pipeline container through a separator, coarse starch is sieved, separated into another pipeline container, so as to obtain fiber particles and coarse starch granules....

Abstract

The invention relates to a method for extracting dietary fiber in the production of bean starch and belongs to the technical field of bean starch production and processing. The method for extracting the dietary fiber in the production of the bean starch is characterized by comprising the following processing steps of: 1, grinding; 2, screening; 3, softening and decoloring; 4, dehydrating; and 5, drying. In the method for extracting the dietary fiber in the production of the bean starch, mechanical equipment is adopted in the overall process, so that manpower is saved, manual experienced operation is not needed, the utilization rate of raw materials is improved, water consumption in the production process is reduced, discharged sewage is also reduced correspondingly, and pollution on environment is avoided; and the method has the characteristics of stable process, suitability for mechanized production and low cost.

Description

technical field [0001] The invention relates to a method for extracting dietary fiber, which belongs to the technical field of bean starch production and processing. Background technique [0002] Mung beans and peas are leguminous plants mainly composed of starch, protein and fiber, and are widely planted in many places in my country. At present, the starch resources in mung beans and peas can be fully utilized in China, but the utilization of their protein and fiber is limited to feed. Zhaoyuan City is the birthplace and main production area of ​​Longkou vermicelli in China. It has more than 120 large and small vermicelli enterprises, with an annual output of more than 200,000 tons of Longkou vermicelli. As the main raw materials for the production of Longkou vermicelli, mung beans, peas and their starch products The usage of green (pea) beans is increasing year by year, and the annual consumption of green (pea) beans is nearly 400,000 tons. However, while producing green...
