Temperature control system and control method of Antarctic krill cooking equipment

Abstract

The invention provides a temperature control system and a control method of Antarctic krill cooking equipment. The Antarctic krill cooking equipment is a scraper type heating device, and the heat source input of the scraper type heating device is provided with two PID steam heating circuits. The first PID The heating line is provided with No. 1 steam filter, No. 1 steam pressure reducing valve, No. 1 pressure sensor, No. 1 solenoid valve, main electric regulating valve and No. 2 solenoid valve in sequence in the direction from the steam inlet to the scraper heating device. No. 2 steam filter, No. 2 steam pressure reducing valve, No. 2 pressure sensor, No. 3 solenoid valve and secondary electric regulating valve are arranged in sequence in the direction of the steam inlet to the scraper heating device in the second PID heating line; scraper heating The device is equipped with a steam discharge pipeline, and there are temperature sensors at the material inlet and outlet ends of the scraper heating device. The present invention ensures the precise control of the Antarctic krill cooking temperature through the controllable adjustment of the steam pressure, and further helps to improve the product quality of the Antarctic krill powder.

Description

technical field [0001] The invention relates to the processing of Antarctic krill, in particular to a temperature control system and a control method of Antarctic krill cooking equipment. Background technique [0002] Antarctic krill is one of the most abundant single species of organisms on earth. It is estimated that the biomass of Antarctic krill is about 650-1000 million tons. The annual catchable amount of Antarctic krill is about 60 million to 100 million tons, which is equivalent to the total production of marine fish and crustaceans in the world for a year. Antarctic krill is the fourth largest resource on earth after grain, petroleum, and coal, and Antarctic krill and grain are both renewable resources. Antarctic krill has extremely high nutritional value and has been paid more and more attention by people. [0003] Antarctic krill live in seawater at 0-1°C. Once the water is caught, the special protease located in the cephalothorax will change due to the tempera...

Problems solved by technology

Therefore, it is necessary to process Antarctic krill in a short period of time, generally into frozen Antarctic krill or Antarctic krill meal. During the process of processing Antarctic krill meal, Antarctic krill needs to be cooked. During the cooking process, the temperature The requirements are relatively high, and the cooking technology of the current fishing boats is backward, and the nutritional value of the produced Antarctic krill products is seriously lost. Therefore, how to control the temperature of the cooking equipment more accurately, and then improve the Antarctic krill products. Quality is a technical problem to be solved urgently by those skilled in the art
