Description

Technical Field

[0001] The invention relates to the technical field of essence extraction, and in particular to a device for preparing essence extracted from natural plants. Background Art

[0002] Plant extraction is the extraction of plant components from naturally growing plants. The extracted plant components are collectively called plant extracts. Plant extracts refer to substances extracted or processed from plants (all or part of a plant) using appropriate solvents or methods. They can be used in the pharmaceutical industry, food industry, health industry, beauty industry and other industries. They are most widely used in the pharmaceutical and beauty industries. Due to their wide sources and good effects, they are becoming more and more popular.

[0003] The existing method of extracting substances from plants is generally to use distillation. In the actual operation, the plant to be distilled is put into a distiller, and the distiller is heated by a heater arranged at the bottom of the distiller. After heating, the extract in the plant evaporates together with the water, and finally the evaporated water is liquefied by a condenser, and the plant extract can be obtained after standing and separation.

[0004] At present, in the distillation process, the plant materials to be distilled are directly put into the distiller, mixed with water and then boiled. During the boiling process, since the heating is carried out from the bottom wall of the distiller, the water and the plant materials in the distiller are easily heated unevenly, which affects the efficiency of distillation. At the same time, as the distillation proceeds, the water evaporates, and the plant materials sink to the bottom and adhere to the bottom wall of the distiller after being heated. It is not easy to clean after the distillation is completed. Moreover, when cleaning the residual water in the distiller after the distillation is completed, since the heating part is located below the distiller, it is necessary to dump the distiller or salvage the residual water and plant residues inside. There are many operation steps and it is more labor-intensive and troublesome to clean up. It is not convenient to continuously distill and extract the plant materials, which affects the extraction efficiency during batch extraction. Summary of the invention

The water in the cooking chamber 111 passes through the filter plate 14 to submerge the plant raw material, and is heated by the heating part 3 arranged around the cooking mechanism 1. The mixed steam of the evaporated plant raw material and water enters the condensing mechanism 2 to condense and restore into liquid, and the discharge port 12 discharges the residual liquid in the cooking chamber 111. The setting of the heating part 3 effectively increases the contact area between the water in the cooking chamber 111 and the heating part 3, thereby improving the heating efficiency and uniformity of the water. The carrying plate 13 prevents the plant raw material from contacting the inner bottom wall of the cooking chamber 111 during the boiling process, thereby avoiding the occurrence of sticking to the bottom, and suspends the plant raw material to avoid part of the plant raw material sinking to the bottom. During the boiling process, the plant raw material can be heated more evenly in the water. With the function of the filter screen, it is convenient to drain the water of the plant raw material after the boiling is completed and clean it up.

The splicing block is fixedly connected to the fixed end of the heating rod 331 for installing and positioning the heating rod 331. A through hole is provided on the mounting shell 31 for slidingly connecting the locking bolt. The locking bolt penetrates into the surface of the mounting shell 31 and fixes the splicing block through a threaded connection. The locking bolt is connected to the threaded hole on the splicing block to firmly fix the heating rod 331 to the mounting shell 31, thereby ensuring the stability of the position of the heating rod 331, facilitating the installation and removal of the heating rod 331, and improving the convenience of equipment maintenance.

Two adjacent condensing tubes 21 are spliced ​​by the splicing tube 22. The cooling water jacket 23 is sleeved on the outer surface of the condensing tube 21. The condensing tube 21 is used to guide the steam through the inside thereof and perform heat exchange with the cooling medium to condense the steam into liquid. Through the arrangement of multiple condensing tubes 21, the uncondensed steam of one condensing tube 21 will enter the adjacent other condensing tube 21. Condensation continues in the condenser 21 to improve the processing effect of steam condensation.
