Embodiment Construction

[0026] The chitin preparation method of the present invention comprises the following steps: pulverize the chitin raw material, and send the pulverized chitin powder into the reaction kettle; add acid solution to decompose the inorganic salt; the obtained liquid leads to a filter device; dehydrate the filtrate to obtain Chitin. The dehydration of the filtrate is achieved by vacuum distillation.

[0027] See figure 1 —4. The chitin preparation method of the present invention is applied to a filter device. The structure of the filter device includes a support and a number of solid-liquid separation units. The support includes a fixed block 2, a liquid guide block 10 and two cross bars 5. These two cross bars 5 The two ends of the cross bar 5 are connected with the fixed block 2 and the liquid guide block 10 respectively.

[0028] The main structure of the solid-liquid separation unit is a frame-type filter frame 6, and a protruding handle 7 is provided on opposite sides of the...

Abstract

A disclosed chitin preparation method comprises the following steps: crushing a chitin raw material, and sending crushed chitin into a reaction kettle; adding an acid liquid to perform acidolysis for removing inorganic salts; sending the obtained liquid to a filtering apparatus; and dewatering the obtained filtrate, so as to obtain chitin. The filtering apparatus comprises a support and multiple solid-liquid separation units, the support comprises a fixing block and a liquid-guiding block; two transverse rods for connecting the fixing block and the liquid-guiding block is arranged therebetween, and the two transverse rods are arranged at intervals in a parallel way; the main structure of each solid-liquid separation unit is a filtering frame, the filtering frame is provided with a filter screen, two opposite lateral sides of the filtering frame are both provided with a protruded handle; the filtering frames are horizontally superposed between the two transverse rods in a parallel way, and the handles are naturally put on the transverse rods; the fixing block is provided with a jacking device for performing jacking on the filtering frames; and under the effect of the jacking device, the filtering frames press the internal surface of the liquid-guiding block, one end of a liquid-guiding pipe leads to the internal surface of the liquid-guiding block, and the other end of the ilquid-guiding pipe is communicated with the reaction kettle. The preparation method is high in production efficiency.

Description

technical field [0001] The invention relates to a preparation method of chitin, which belongs to the technical field of medicine and chemical industry. Background technique [0002] Chitin is a 1,4-linked 2-acetylamino-2-deoxy-β-D-glucan widely present in the cell walls of insects, crustaceans and fungi. Every year, chitin biosynthesized on the earth can reach tens of billions of tons, and it is the second largest renewable natural polymer after cellulose in nature. The unique molecular structure of chitin endows it with fascinating biological activity. A large number of studies have shown that in addition to non-toxic, good biocompatibility, biodegradability and other properties, chitin also has special properties such as hemostasis, analgesia, promotion of wound healing, and antibacterial. [0003] A Chinese invention patent (publication number: 102086464A) discloses a preparation method of chitin. The preparation method mainly discloses the method of desalting the pulve...
