Description

Technical Field

[0001] The invention relates to the technical field of automatic control of agricultural product processing, and in particular to a cold water system in a lycopene production process. Background Art

[0002] With the continuous advancement of lycopene production technology, the importance of the chilled water system as a key supporting facility has become increasingly prominent. The system is usually composed of multiple components such as chillers, cold water storage tanks, and cold water circulation pumps, and is designed to provide a stable and efficient cooling water source for heat exchange during the production process. In recent years, as the concept of energy conservation and environmental protection has become popular, the design of the chilled water system has also paid more attention to energy efficiency and environmental protection performance, such as the use of closed-loop circulation systems to reduce the discharge of wastewater and waste residues.

[0003] The chilled water system mainly serves the heat exchange process in the lycopene production process. Specifically, the chiller is responsible for refrigeration and produces the required low-temperature cold water; the cold water storage tank is used to store this cold water for emergency use. The cold water circulation pump transports cold water to each link that requires cooling, such as extraction and separation. At the same time, the carbon dioxide pump and carbon dioxide storage tank involve the supercritical carbon dioxide extraction process, which is an advanced technology for extracting lycopene. The condenser, cooling water pump, water tank, cooling tower and other components together constitute a complete circulation system, which enables the continuous supply and recycling of cold water.

[0004] However, the existing cold water system in the lycopene production process has the following technical pain points. In the large-scale production of lycopene, the complexity of maintaining the cold water system in the lycopene production process also increases the operating costs. The coordinated work of multiple components in the cold water system in the lycopene production process requires regular inspection and maintenance. If the cold water system in the lycopene production process is not maintained and repaired in time, the cooling efficiency of the cold water system in the lycopene production process will be reduced, especially in high temperature or high humidity environments. The cooling effect of the cold water system in the lycopene production process is affected, thereby affecting the production efficiency and quality of lycopene. Summary of the invention
