Natural compound preservative for preserving beverages

Abstract

The invention discloses a natural compound preservative for preserving beverages. The natural compound preservative is prepared from a radix salviae miltiorrhizae extraction solution, a smoked plum extraction solution and a cinnamon extraction solution, so the natural compound preservative has a good bacteria resisting and restraining effect and has a good preservative effect. The raw materials adopted for the natural compound preservative all come from natural plants, and the preservative prepared from the natural plants has a quite small toxic and side effect on a human body and even has notoxic or side effect. A grinding device for grinding the raw materials into powder completes the process of automatically cutting and grinding objects needing to be ground, and is simple in structureand easy to operate. A sieve plate is installed in the device, and work efficiency is improved. According to the grinding device, a replacing channel is arranged on a grinding box body, the sieve plate, a new movable grinding plate and a new fixed grinding plate can be conveniently installed and replaced. A first grinding edge is installed on the movable grinding plate, and a second grinding edgeis installed on the fixed grinding plate, so that the grinding efficiency is high, and the grinding effect is good.

Description

technical field [0001] The invention relates to the field of preservative manufacturing technology, in particular to a natural composite preservative used for beverage storage. Background technique [0002] With the improvement of people's living standards, the beverage industry has developed rapidly, and the storage of beverages is an important issue for the beverage industry. At present, the commonly used methods of beverage preservation at home and abroad are to add chemically synthesized food preservatives such as sodium benzoate, but these chemically synthesized antiseptics The use of preservatives has certain toxic and side effects on the human body. Therefore, the development of natural, efficient, safe and non-toxic food preservatives has become an important topic in food science. There are many antibacterial and antioxidant active substances in natural plants, which are natural food preservatives. Rich resources are available for development and application. [000...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a kind of natural composite preservative for beverage storage: (1) by adopting the purple salvia miltiorrhiza extract that has antibacterial and antibacterial effect, ebony extract, cassia bark extract The antibacterial and antibacterial effect of the natural composite preservative is good, and the antiseptic effect is good, and the raw materials used in the natural composite preservative are all from natural plants, and these preservatives made by natural plants are harmful to the human body. The toxic and side effects are very small, or even have no toxic effect, which solves the problem that the existing chemically synthesized preservatives have certain toxic and side effects on the human body; (2) The first pulley is driven by the rotation of the first motor, and the first gear is driven by the belt Rotate, the first gear meshes with the second gear, drives the first roller and the second roller to rotate through the first rotating shaft and the second rotating shaft, and the first cutting knife on the first roller for the item that needs to be ground The joint with the second cutting knife on the second roller is cut and turned into particles. The particles are between the fixed grinding table and the moving grinding table. The driving grinding table rotates at a high speed through the rotation of the second motor, and the moving grinding table is pushed up by the lifting cylinder. , the particles are ground into powder under the joint action of the movable milling disc and the fixed milling disc; the problems of complex structure, low degree of automation and difficult operation of the existing mill are solved; (3) by installing the sieve plate inside the device, By installing the installation box on the sieve plate, the second motor inside the installation box vibrates while rotating, which drives the vibration of the sieve plate, which solves the problem that the existing mill needs to use A special screening device screens it, a lot of time is wasted from grinding to screening, and the screening device takes up a lot of space; (4) By installing a replacement channel in the grinding box, inserting the sieve plate into the grinding box The sieve plate can be easily replaced in the slot on the inner wall of one side of the body. By threading the fixed grinding disc to the bottom of the inner feeding pipe, the moving grinding disc is threaded on the output shaft of the second motor, which solves the existing problem of grinding powder. It is very difficult to replace new moving grinding discs and fixed grinding discs by machine; (5) by installing some circular first grinding blades on the moving grinding discs and installing some S-shaped second grinding blades on the fixed grinding discs, it can be solved The problem of low grinding efficiency and grinding effect of the grinding disc used by the existing milling machine
