Problems solved by technology

[0003] At present, there are mainly two kinds of open photoreactors and closed photoreactors for the cultivation of Haematococcus pluvialis. The main temperature control methods of these two reactors are traditional drip irrigation or spraying. Due to the limitations of slow temperature speed and waste of water resources, especially in terms of temperature control, it cannot fully and quickly adapt to changes in the outside world. Because Haematococcus pluvialis has strict requirements on the cultivation conditions, it has led to the cultivation process in multiple regions. Because of the breeding temperature, avoid some seasons with harsh environments to stop breeding operations

Embodiment 1

[0019] Such as figure 1 As shown, this embodiment provides a temperature control system for microalgae cultivation based on online feedback automatic temperature regulation, and the system includes the following subsystems:

[0020] The cultivation subsystem 1 is used to provide a safe place and various environmental conditions and physiological conditions required for the growth of microalgae;

[0021] The cold and hot water circulation subsystem 2 is used to provide the cold water and hot water required for temperature adjustment, as well as the corresponding return pipeline. Through the flow of cold and hot water in the return circulation pipeline, it drives the transfer of material energy in the breeding subsystem to achieve The role of temperature regulation;

[0022] The online monitoring and detection subsystem 3 is used to monitor the temperature of the internal materials in the breeding subsystem during operation, and to control the start and stop of the hot and cold...

Abstract

The invention belongs to the technical field of crossing of bioengineering and aquaculture and particularly relates to a temperature control system based on online feedback and automatic temperature adjustment for microalgae cultivation. The temperature control system comprises a cultivation subsystem, a cold-hot water circulating subsystem and an online monitoring and detecting subsystem, wherein the online monitoring and detecting subsystem is connected with the cultivation subsystem and the cold-hot water circulating subsystem, respectively, and the cold-hot water circulating subsystem is connected with the cultivation subsystem. According to the temperature control system, the limited cultivation space of Haematococcus pluvialis due to external temperature environment is solved, and the cultivation domains and seasons of the Haematococcus pluvialis are widened; and meanwhile, the temperature control system is completely automated and intelligentized and simple to operate, so that the labor cost is lowered.

Description

technical field [0001] The invention belongs to the interdisciplinary technical field of bioengineering and aquaculture, and in particular relates to a temperature control system for automatic temperature regulation based on online feedback for the cultivation of Haematococcus pluvialis. Background technique [0002] Astaxanthin, also known as astaxanthin and lobster shell pigment, is a widely distributed ketone type carotenoids. Due to its good coloring function and strong antioxidant capacity, astaxanthin has been widely used in aquaculture, medical and health care, cosmetics and health care products and other industries. Haematococcus pluvialis (Haematococcus pluvialis) is a freshwater single-celled green algae. It is currently known as the biological species with the highest content of astaxanthin. The highest content reaches 4-6% of the dry mass. It is considered to be an ideal natural shrimp Cyanide producers. The life cycle of Haematococcus is mainly divided into...
