Problems solved by technology

This process has caused a common misunderstanding, that is, kelp blanching water contains more organic matter and causes more serious pollution, while cooled seawater has less organic matter content and less pollution. To control kelp blanching pollution, it is only necessary to control kelp blanching water. Can

Embodiment 1

[0020] An energy-saving recycling treatment method for soluble organic matter in kelp blanching water, comprising the following steps:

[0021] ①The blanching water is pumped from the blanching pot and passed through the spray device to directly spray the fresh kelp raw materials during the transmission process at the end close to the feeding conveyor belt. The quality of the spray water is twice the quality of the raw kelp raw materials, and a heat exchange And a section of extraction, the spray water enters the collection tank as the stock solution for use, and the fresh kelp raw material that has been sprayed is used as the raw material for the next step. The temperature of the stock solution for use after heat exchange is controlled at 65-70 ° C. If it exceeds this temperature It needs to be cooled to make the temperature reach the standard before operation;

[0022] ②Step ①The processed raw materials enter the blanching pot through the conveyor belt for blanching processi...

Embodiment 2

[0028] The whole is the same as Example 1, the difference is:

[0029]①Pump the blanching water from the blanching pot through the spray device to directly spray the fresh kelp raw materials in the process of conveying at the end near the feeding conveyor belt. The quality of the spray water is 0.5 times the quality of the raw kelp raw materials, and a heat exchange And a section of extraction, the spray water enters the collection tank as the stock solution for use, and the fresh kelp raw material that has been sprayed is used as the raw material for the next step. The temperature of the stock solution for use after heat exchange is controlled at 60 ° C. If it exceeds this temperature, it needs to be Cool to make the temperature reach the standard before operation;

[0030] ②Step ①The processed raw materials enter the blanching pot through the conveyor belt for blanching processing. During the blanching process, the soluble organic matter in the kelp raw materials enters the ...

Embodiment 3

[0034] The whole is the same as Example 1, the difference is:

[0035] ①The blanching water is pumped from the blanching pot and passed through the spray device to directly spray the fresh kelp raw materials during the transmission process at the end close to the feeding conveyor belt. The quality of the spray water is 3.0 times the quality of the raw kelp raw materials, and a heat exchange is performed. And a section of extraction, the spray water enters the collection tank as the stock solution for use, and the fresh kelp raw material that has been sprayed is used as the raw material for the next step. The temperature of the stock solution for use after heat exchange is controlled at 75 ° C. If it exceeds this temperature, it needs to be Cool to make the temperature reach the standard before operation;

[0036] ②Step ①The processed raw materials enter the blanching pot through the conveyor belt for blanching processing. During the blanching process, the soluble organic matte...

Abstract

The invention relates to an energy-saving recycling treatment method for soluble organic matters in kelp blanching water. The energy-saving recycling treatment method comprises six main steps as follows: sprinkling in the conveying process of a fresh kelp raw material, blanching the raw material in a blanching pot after sprinkling, performing high-temperature nanofiltration on a sprinkling liquid after purification of the sprinkling liquid, performing three-section extraction on the sprinkling liquid, salting the kelp raw material after the three-section extraction to obtain a salted finished kelp product, performing ultrafiltration purification separation on multi-stage sprinkling liquid and the like. By the treatment method provided by the invention, a one-time blanching water heating and multi-stage heat recovering process is adopted, heat obtained during one-time heating is successively utilized through multi-stage blanching, and the extracting process is speeded up. Therefore, the efficiency is improved and the energy is saved.

Description

technical field [0001] The invention relates to the field of kelp extraction, in particular to an energy-saving and circular treatment method for soluble organic matter in kelp blanching water. Background technique [0002] my country is the world's largest seaweed breeding and processing country, of which the total amount of kelp in our country is 1.4 million tons, most of which are salted products. However, as a traditional aquatic product processing industry, the kelp processing industry generally has a series of problems such as extensive processing mode, low processing technology level, and insufficient resource utilization rate. In particular, other resources except seaweed have not been paid attention to. Most of the soluble active ingredients are discharged along with the waste water generated by blanching and cleaning during the primary blanching process and food processing, and are basically not utilized. The wakame industry basically faces the same situation as t...
