Example Embodiment

[0035] Embodiment one

[0036] A kind of high-efficiency fermentation compound chitin extraction process, the setting of fermentation parameters in the described a kind of high-efficiency fermentation compound chitin extraction process is:

[0037] 1). Medium sterilization temperature Pasteurization temperature: 78.9°C;

[0038] 2). Anaerobic: The fermentation temperature is 35°C, turn on the nitrogen, and adjust the flow meter on the panel to 67LPM;

[0039] 3). Aerobic: Fermentation temperature is 32°C, air flow rate, initial pH value is 6.6, set pH value is 6.7;

[0040] 4). Aerobic: Turn on the compressed air and adjust the flow meter on the panel to 57LPM;

[0041] 5). pH control anaerobic: initial pH 6.1, pH set value 5.

[0042] Through precise setting of fermentation parameters, the efficiency of fermentation and the precision and rate of chitin extraction can be further improved.

Example Embodiment

[0043] Embodiment two

[0044] The efficient fermented compound chitin extraction process includes the following steps:

[0045] Step 1: Receive and store the raw materials. The raw materials are natural shrimp and crab, sugar and citric acid.

[0046] Step 2: Grinding the shrimps and crabs in the raw materials, using ultra-clean ultra-fine powder grinding technology and equipment during grinding.

[0047] Step 3: Fully mix the ground shrimp and crab with sugar and citric acid,

[0048] Step 4: Ferment the mixture of raw materials, using microbial integrated fermentation technology.

[0049] Step 5: Using low-temperature extraction technology to extract the fermented raw materials, and finally micronize the prepared chitin, and then pack it.

[0050] The efficiency of biological fermentation to extract chitin is 10 times that of acid-base method and 5 times that of enzymatic hydrolysis. 1 / 3 of the method, 1 / 5 of the enzymatic method.

Example Embodiment

[0051] Embodiment three

[0052] There are 21 types of microorganisms in an efficient fermented compound chitin extraction process. The extracted chitin can be used as fish feed in fishery, cosmetic beauty agent, hair protection, moisturizer, etc., and can be used as contact lens, medical supplies, etc. Artificial skin, sutures, artificial dialysis membranes and artificial blood vessels, etc.

Abstract

The invention relates to the technical field of chitin extraction, in particular to an efficient fermentation composite chitin extraction process, and solves the problems that in the prior art, when chitin is extracted, the efficiency is low, pollution is large, no derivative exists, and the utilization rate is low, so that the overall extraction efficiency of chitin is greatly influenced, and the cost is low. In the prior art, the problems of difficult degradation, great influence on the complete use process of chitin, and great inconvenience are solved in the prior art. The invention relates to a high-efficiency fermentation composite chitin extraction process, which comprises the following steps: receiving and storing raw materials, grinding shrimps and crabs in the raw materials by using an ultra-clean ultra-fine powder grinding process and equipment, and fully mixing the ground shrimps and crabs with sugar and citric acid. The extraction efficiency is improved, no waste water is generated, so that the cost is lower and is only 1/3 of that of an acid-alkali method and 1/5 of that of an enzymolysis method, the price is low, and the product quality is good.

Description

technical field [0001] The invention relates to the technical field of chitin extraction, in particular to a high-efficiency fermentation compound chitin extraction process. Background technique [0002] Chitin is used for many different purposes in industry. Chitin is used for water and wastewater purification. It is used as a food additive to thicken food and medicine to stabilize the state of food and medicine. Chitin can also be used as a dye, fabric , Adhesives, industrial separation membranes and ion exchange resins can be made of chitin, and chitin is also used for the size and strength of processed paper. [0003] In the prior art, when extracting chitin, there are often problems of low efficiency, large pollution, no derivatives, and low utilization rate, which greatly affects the overall extraction efficiency of chitin, and there is a problem that it is difficult to degrade, which greatly affects It is extremely inconvenient to complete the use process of chitin, ...
