Equipment for extracting dietary fiber from wheat bran

Abstract

The invention discloses equipment for extracting dietary fiber from wheat bran. The equipment comprises a reaction device and a separation device, wherein the reaction device can be used for performing steaming boiling heating and modification on the wheat bran; the wheat bran mixed liquid after modification is completed enters the separation device to be subjected to centrifugal separation; water-soluble dietary fiber and water-insoluble dietary fiber are respectively obtained and are respectively fed into a spray drying machine and an ultrafine crushing machine to be made into dietary fiberpowder. The device provides a set of complete extraction equipment; the production process from raw materials to finished product has few steps; the efficiency is high; the fast industrial productionis facilitated; a novel path is provided for the further resource utilization of the wheat bran.

Description

technical field [0001] The invention relates to the field of dietary fiber preparation, in particular to a device for extracting dietary fiber from wheat bran. Background technique [0002] Dietary fiber is an internationally recognized functional food base, known as the "seventh nutrient" in addition to the six major nutrients of water, protein, carbohydrates, lipids, vitamins and minerals. In the 21st century, it is a food additive that has received the most attention in the food industry and has special health care functions and food modification effects. Dietary fiber can be used as an effective functional health food to prevent various diseases, and has special effects such as water retention, oil retention, and improvement of food color and flavor. It can improve human digestion and absorption, enhance human excretion, and promote human dietary structure. Balance, hinder the body's excessive absorption of some nutrients, maintain functional balance, have anti-cancer, ...

Problems solved by technology

[0003] Wheat bran is a by-product of the wheat flour milling process. The annual output of wheat bran in my country can reach more than 20 million tons, but it is rarely developed and utilized. It is only used as a feed material. The main reason is its taste, The taste is not good, so it cannot be eaten; according to relevant research reports, the mass fraction of ferulic acid in wheat bran is 0.4% to 0.7%; the use of by-products has attracted attention at home and abroad. The processing and utilization of by-products will contribute to the environment and economy;

[0004] However, the current method of extracting dietary fiber from wheat bran does not have a complete set of equipment. Workers often use traditional reaction vessels to prepare by enzymatic-chemical method or simple enzymatic method, but repeatedly soaked in water Washing and frequent heat treatment will significantly reduce the water holding capacity and swelling of fiber products, and involve a large number of containers, the operating environment is messy, and there are many steps in the extraction process of dietary fiber. It is time-consuming, inefficient, and dangerous. Therefore, a set of high-efficiency, low-cost, safe and feasible bran dietary fiber extraction equipment is established to provide a new way for further resource utilization of bran. It is of great significance to increase the economic added value of wheat planting and give full play to the industrial advantages of my country's wheat
