Device and method for continuously extracting dietary fibers from cereal bran

Abstract

The invention relates to a device and method for continuously extracting dietary fibers from cereal bran, and belongs to the field of development and application of the cereal bran. The device adoptsthe main technical scheme that a first vacuum charging machine is connected with immersion tanks, the outlets of the immersion tanks are connected with a temporary storage trough, the temporary storage trough is sequentially connected with a sanitary pump I, a first extruding separator, a first buffer tank and a sanitary pump II, the sanitary pump II is connected with an inlet of an acidolysis tank and an inlet of an alkaline hydrolysis tank, the first extruding separator is connected with a sedimentation basin, and an outlet of the acidolysis tank and the outlet of the alkaline hydrolysis tank are connected with the temporary storage trough; and the sanitary pump II is connected with a first-class tunnel type washer, the first-class tunnel type washer is connected with the inlet of a second buffer tank, and the outlet of the second buffer tank is connected with a second-class tunnel type scrubber and a second extruding separator respectively. Through the adoption of the device and themethod provided by the invention, fat and lignin in cereal materials can be fully degraded, so that continuous extraction and washing of cereals can be realized, and the device and the method have the characteristics of being high in extraction efficiency and low in cost.

Description

technical field [0001] The invention belongs to the field of development and application of grain bran, in particular to a device and method for continuously extracting dietary cellulose from grain bran. Background technique [0002] Dietary fiber is a nutrient that maintains human health and cannot be replaced by other substances. It is a general term for a complex mixture. People call it the six major nutrients following carbohydrates, fats, proteins, vitamins, water, and minerals. The "seventh nutrient" of the human body. Wheat bran, bean dregs, and corn bran all contain lipids and lignin on the surface. If they are directly crushed, not only the edible quality is poor, but also the effect of dietary fiber cannot be achieved. [0003] Lignin is an aromatic non-sugar substance with a phenylpropane skeleton. It mainly exists in the interlayer of fiber cells and cell walls. Like glue, it sticks fibers together one by one to form plants. The more lignin in raw materials Mor...

Problems solved by technology

The development and application of dietary fiber food in foreign countries has been relatively common. At present, the research and development of dietary fiber in my country is still in its infancy, and no large-scale processing enterprises have been formed.
