Temperature control system and temperature control method of euphausia superba cooking equipment

Abstract

The invention provides a temperature control system and a temperature control method of euphausia superba cooking equipment. The euphausia superba cooking equipment is a scraper type heating device; aheat source input of the scraper type heating device is provided with two PID steam heat supply lines; the first PID heat supply line is sequentially provided with a first steam filter, a first steampressure reducing valve, a first pressure sensor, a first electromagnetic valve, a main electric control valve and a second electromagnetic valve in the direction from the steam inlet to the scrapertype heating device. The second PID heat supply line is sequentially provided with a second steam filter, a second steam pressure reducing valve, a second pressure sensor, a third electromagnetic valve and a secondary electric control valve in the direction from the steam inlet to the scraper type heating device. The scraper type heating device is provided with a steam exhaust pipeline, and temperature sensors are arranged at the material inlet end and the material outlet end of the scraper type heating device respectively. Through the controllable adjustment of the steam pressure, the accurate control of the cooking temperature of the euphausia superba is guaranteed, and the product quality of the euphausia superba powder is improved.

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
