Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ferulic acid preparation, and particularly relates to a ferulic acid preparation enzymatic hydrolysis device and method. BACKGROUND

[0002] Ferulic acid is a natural antioxidant and anti-inflammatory agent widely used in the food, pharmaceutical and cosmetic industries, and it is usually obtained by hydrolyzing ferulic acid ester bonds in plant raw materials through enzymatic hydrolysis. The core equipment of the enzymatic hydrolysis process is the enzymatic hydrolysis reactor, and its performance directly determines the extraction efficiency and product yield of ferulic acid.

[0003] In the prior art, the enzymatic hydrolysis device for preparing ferulic acid usually uses a reactor with a stirring device. Specifically, the device includes a tank body, a feed inlet and an enzyme addition port are arranged on the upper part of the tank body, a discharge port is arranged on the lower part of the tank body, and a mechanical stirring paddle (such as an anchor type or paddle type stirrer) driven by a motor is installed at the central position in the tank. When working, the raw material slurry containing ferulic acid precursors (such as rice bran and wheat bran) and specific enzyme preparations (such as ferulic acid esterase) are fed into the tank through the feed inlet, and the motor is started to drive the stirring paddle to rotate in one direction, so as to uniformly mix the raw materials and enzyme liquid, and perform enzymatic hydrolysis reaction under the set temperature and pH conditions.

[0004] However, the existing enzymatic hydrolysis device has obvious defects. The most important defect is that due to the single stirring mode and the existence of stirring dead angles, the solid enzymatic raw materials with high density (such as bran particles) are prone to deposit and accumulate in the central area of the bottom of the reactor. During the enzymatic hydrolysis reaction, these deposited raw materials will adhere to each other due to their own viscosity and the viscosity of the enzymatic hydrolysis products, forming clumps that are difficult to break up. The mass transfer barrier is formed inside the clumps, and the enzyme liquid outside cannot effectively penetrate into the inside to fully contact with the substrate, resulting in that the internal ferulic acid precursors cannot be fully hydrolyzed, and finally causing problems such as decreased extraction rate, raw material waste, prolonged reaction period, increased energy consumption, etc., which seriously restricts the production efficiency and reduces the economic benefits.
