A kind of nitrite scavenging additive production line and its preparation method

Abstract

The invention discloses a nitrite scavenging additive production line, which belongs to the field of chemistry and includes a cleaning device, a drying device, a crushing device, an extraction device, a complexing reaction kettle and a precipitation filtering device from front to back, and the complexing reaction kettle includes a reaction kettle The shell, the stirring components of the reactor and the ultrasonic generator, the overall shell of the reactor is like a cylinder, the upper and lower sides are convex arc-shaped surfaces, the top surface is formed with the reactor inlet, and the middle of the bottom surface forms the reactor The discharge port and the reactor stirring assembly are installed on the top surface of the reactor shell and are coaxial with the central axis of the reactor shell, and the ultrasonic generator is installed on the circumferential side of the reactor shell. The beneficial effects of the present invention are: adding ultrasonic waves in the complexation reaction kettle to heat and mix the solution, effectively improving the movement activity of proanthocyanidins and aluminum ions in the solvent, increasing the contact chance of grape seed proanthocyanidins and aluminum ions, thereby improving the Reaction efficiency and complex stability.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a nitrite scavenging additive production line and a preparation method thereof. Background technique [0002] Grapes are deciduous vines belonging to the genus Vitis, and are one of the most commonly cultivated fruits in the world. They are treasures in fruits and are known as the "Queen of Fruits". Grape is an important fruit tree in my country. With the reform and opening up and the adjustment of rural industrial structure, the viticulture industry in my country has developed accordingly. Especially in the past ten years, the cultivated area and output of grape have been on the rise. In 2005, the cultivated area of ​​grapes in my country was 408,100 hm 2 , ranking No. 4 in the world, with an output of 5.794 million tons, ranking No. 5 in the world. [0003] Proanthocyanidins are a large class of flavonoid polyphenolic compounds that are ubiquitous in woody and herbaceous plants. In ...

Problems solved by technology

[0005] Aiming at the problems of low extraction efficiency of grape seed proanthocyanidins in the prior art, large amount of solvent consumption, long extraction time, low extraction rate and low application value, the present invention provides a nitrite scavenging additive production line, from before to After that, it includes cleaning device, drying device, pulverizing device, extraction device, complexation reactor and precipitation filtration device, and the complexation reactor includes a reactor shell, a reactor stirring assembly and an ultrasonic generator, and the reactor shell The whole body is like a cylinder, and the upper and lower sides are convex arc-shaped surfaces. The top surface forms a reactor feed port, and the middle of the bottom surface forms a reactor discharge port. The reactor stirring assembly is installed on the reaction tank. On the top surface of the kettle shell and coaxial with the central axis of the reactor shell, the ultrasonic generator is installed on the circumferential side of the reactor shell
