Indigo extracting device based on bluegrass and preparation process

Abstract

The invention discloses an indigo extracting device based on bluegrass and a preparation process. The indigo extracting device comprises a container; an accommodating groove is formed in the container; sliding rails are fixedly welded to the inner walls of the accommodating groove; the bottoms of the sliding rails are fixedly connected with limiting plates; sliding blocks are slidably connected tothe sliding rails; inserting grooves are formed in the tops of the sliding blocks; inserting plates are inserted into the inserting grooves; a pressing plate is fixedly connected between the inserting plates; a filter screen is embedded in the pressing plate; connecting ropes are fixedly connected to the tops of the inserting plates; the top ends of the connecting ropes are fixedly connected withhanging rings; and hooks are fixedly welded to the outer walls of the two sides of the top of the container. The device has the beneficial effects that a special container is designed, indigo extraction can be assisted through the container, the indigo preparation efficiency is improved, the production period is shorter, the production process is simpler and more convenient, the extraction process is clear, the operation is convenient, the cost is lower, the proportion is definite, and large-batch production can be promoted.

Description

technical field [0001] The invention discloses an indigo extraction device and a preparation process based on indigo grass, belonging to the technical field of indigo extraction. Background technique [0002] Dye bluegrass refers to the collective name of various plants that can produce indigo dye and are used for dyeing cloth. It cannot be confused with flower bluegrass. The appearance, family, composition, and name of the two are completely different. In fact, blue and bluegrass are ancient names. , modern folks generally call it blue indigo; [0003] Generally speaking, blue indigo is mostly extracted from indigo, but in the existing technology, most of the operations in the process of extracting indigo are complicated, so that the extraction efficiency of blue indigo is low, and production cannot be popularized. Therefore, the present invention proposes a new Bluegrass-based blue indigo extraction device and preparation process. Contents of the invention [0004] The...
