Yeast manufacturer, Angel Yeast is accelerating green transformation in its factory workshops by implementing a series of intelligent, automated, and sustainable technologies that not only improve production efficiency, but also contributes to the sustainable development of the industry.
In the company's yeast production workshop in Yichang, located in the Hubei Province in China, Angel Yeast has installed an intelligent air-conditioning system to replace the traditional cooling method that relies heavily on large quantities of cooling water and manual labour.
The refrigeration system cluster intelligent control project optimizes the operation through APC control technology.
When the water pressure, water temperature or environment temperature changes, the system adjusts automatically – for example, when the system detects the temperature of circulating water reaches a preset value, the fan frequency will be reduced automatically and the number of operating fans will be minimised, effectively lowering power consumption.
The initiative has improved energy efficiency by 18 per cent, saving up to 5 million kWh of electricity per year.
Angel Yeast an automated steam boiler with a DCS+APC control program; heat recovery technology that replaces the cooling water of the steam seal heater with demineralized water, which is then heated by the waste heat from the exhaust steam.
It is then sent to the deaerator; and heat exchange equipment at the back end of the deaerator exhaust pipe delivers full recycling of waste heat, saving nearly 130 tonnes of standard coal per year.
In 2024 to date, Angel Yeast has invested $US5.52 million and carried out more than 40 technological transformation projects directly related to energy conservation.
Additionally, it has stepped up laying out clean energy operations such as biomass and green power, and strengthened energy control to achieve a 2.5 per cent year-on-year reduction in terms of comprehensive energy consumption and energy cost of producing every tonne of yeast from January to May this year.
Deputy general manager of the Angel Yeast Yichang Plant, Xiong Feng, said Angel Yeast has always made energy saving and emission reduction a core part of its development strategies.
“As a socially responsible corporation, we are committed to leading the green transformation through technological innovation and responding to the global climate crisis with concrete measures," Feng said.
