Description

A mint essence screening device with crushing function

Technical Field

The utility model relates to the field of screening devices, in particular to a mint essence screening device with a crushing function.

Background Art

Mint flavor is a natural flavor widely used in medicine, food, cosmetics and other fields. Its unique aroma and medicinal ingredients make it popular among consumers. It is made from the herb mint through distillation, solvent extraction and other methods. The mint flavor used in the industrial industry exists in two different forms: liquid and solid particles according to different storage and sales needs.

When mint flavor in the form of solid particles is used in different industries, the requirements for its particle size are different. For example, for food dissolution processing, powdered mint flavor with smaller particles is mostly used, while for industrial production additives, large-particle mint flavor with larger particles and lower cost is mostly used. Therefore, for different uses, large quantities of mint flavor need to be screened by screening to obtain the required particle size. Sometimes, the mint flavor raw materials with larger overall particle size need to be further ground and crushed. However, the current screening device does not have a crushing effect. If the existing crushing device is simply loaded into the screening device, all the mint flavor raw materials will be crushed into powder, and the screening effect cannot be obtained.

Therefore, in view of the fact that the above-mentioned mint flavor has different particle size requirements in different industrial uses, and the existing screening devices and crushing devices cannot simultaneously meet the requirements of screening and crushing of the mint flavor as needed, a device that reasonably integrates the screening and crushing devices can be designed. According to the needs of industrial use, the mint flavor raw materials can be selected for simple screening or fine grinding, which is flexible to use.
