Embodiment 1

[0027] Such as Figure 1 to Figure 6 As shown, a chitin production method is characterized in that, the following steps are realized by adopting an integrated device for producing chitin: 1. Centrifugal drying after washing raw materials; 3. Wash the raw materials after the first pickling and decalcification with water. After the washing is completed, they are centrifuged and dried; Tube 7 is heated to sodium hydroxide; 5, the raw material after the first boiling soda, degreasing and deproteinizing is washed with water, and after the washing is completed, it is centrifugally dried; 6, drying.

[0028] Specifically, there is a raw material pretreatment step before step 1. The raw material pretreatment includes cleaning and extruding the impurities of the raw material. The purpose of extruding is mainly to separate the moisture and protein contained in a part of the raw material in advance, and reduce the cleaning water and hydrochloric acid and The consumption of sodium hydrox...

Embodiment 2

[0078] The content in the present embodiment is the same as that of the first embodiment, the difference is that in the present embodiment, a method for producing chitin comprises, adopting an integrated device for producing chitin to realize the following steps: 1, centrifuging after washing the raw material Drying; 2. For the first pickling and decalcification of raw materials, 10% concentration of hydrochloric acid is used for soaking; 3. The raw materials after the first pickling and decalcification are washed with water. After washing, they are centrifugally dried; Soda boiling, degreasing and deproteinizing, soaking in 16% sodium hydroxide and heating the sodium hydroxide with steam pipe 7; 5. Washing the raw materials after the first soda boiling, degreasing and deproteinizing, after washing, centrifugal drying; 6 1. Pickling and decalcification of the raw materials for the second time, soaking with 6% hydrochloric acid; 7. Wash the raw materials after the second picklin...

Abstract

The invention provides a chitin production method. The method is characterized in that an integrated device for production of chitin is used to achieve the following steps: 1, washing a raw material and drying by centrifuging; 2, carrying out first pickling on the raw material for de-calcification; 3, washing the raw material after first pickling for de-calcification, and drying by centrifuging after washing; 4, carrying out first alkali boiling on the raw material for degreasing and deproteinization; 5, washing the raw material after first alkali boiling for degreasing and deproteinization, and drying by centrifuging after washing; and 6, drying by baking. According to the chitin production method, through the integrated device for production of chitin, steps of washing, pickling for de-calcification, alkali boiling for degreasing and deproteinization, drying by baking, etc. of the raw material are achieved without the need of replacing production equipment. Therefore, time is saved, work efficiency is high, and labor intensity is low.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a method for producing chitin. Background technique [0002] Chitin is a nitrogen-containing polysaccharide, also known as chitin, chitin, shell protein, chitin, clear cutin, etc. It is the second most abundant biopolymer in nature and is widely distributed. Especially the important components of the shells of arthropods such as shrimps, crabs, insects, etc. Shrimp shells contain about 15% to 30%, and crab shells contain about 15% to 20%. It is also an integral part of the cell membrane of lower plant fungi, and it is also contained in lichens, green algae, yeast, jellyfish and squid. [0003] At present, in the conventional production method of chitin, the steps of pickling and decalcification, water washing, boiling soda, degreasing and deproteinizing all need to be carried out in different equipments. The operation process is long, the work efficiency is low, and the labor int...
