A citric acid manufacturer in Shandong is a company specializing in the research and development, production and sales of citric acid series products exported to many countries and regions. The products include Citric Acid Monohydrate, Citric Acid Anhydrous, Sodium Citrate, Potassium Citrate, Calcium Citrate and so on.
1. China's fermentation production currently relies mainly on personnel traditional natural fermentation process, the traditional way of labor intensity, long cycle, dependence on the natural environment, and can not achieve large-scale production.
2. Shandong a lemon science and technology company in recent years in citric acid factory scale production has made great progress in Yishui a biological limited company production plant before the construction of the second phase of the project, in the first phase of the base has made a breakthrough in the initial production of citric acid factory production, the project is completed in full, can be an annual output of 500,000 tons of citric acid, sodium citrate (potassium, calcium) of 100,000 tons, 200,000 tons of protein feed, to achieve an annual output value of 80 The project adopts the most advanced technology in the world. The project adopts the world's most advanced production process of “calcium hydroxide method + chromatography + continuous isolated extraction”, which breaks through the technical barriers of low yield and high energy consumption of the traditional calcium salt method, and it is the only enterprise in the industry that has mastered this technology at present. Shandong headquarters is committed to building an international brand of “intelligent manufacturing and smart factory” in the global citric acid industry. It requires more precise control of parameters such as temperature and humidity of the fermentation process in the workshop, as well as higher quality and output of citric acid, and energy consumption per unit of output is required to be reduced by more than 10% compared with the traditional one. 3.
3. As a factory in Shandong aims to be a “smart manufacturing and intelligent factory”, the requirements for automation and intelligence are relatively high, and such a huge factory requires all refrigeration equipment to run automatically, reducing the difficulty for equipment management personnel and management.
In order to meet the needs of the project, a redesign of the program for the project was provided for comparison with the original program.
Divide the entire project into 2 blocks, dehumidification chillers and crystallization chillers.
We used 5 sets of 1750KW Qingfeng wide frequency inverter magnetic levitation chiller can provide stable refrigeration function, to ensure that the temperature and humidity of the citric acid extraction process can be accurately controlled.
The Citric Acid Crystallization Production Center employs three 1750KW inverter magnetic levitation chillers to provide the required cooling and refrigeration functions.
The whole project adopts process refrigeration intelligent control system, computer room group control system and remote monitoring system. These systems are capable of realizing intelligent control and monitoring of temperature, humidity, and other parameters.
Kingfit wide frequency conversion magnetic levitation chiller unit temperature control accuracy of up to ± 0.1 ℃, help fermentation thermostatic control system industrialization, citric acid products, so that its total yield, water consumption, citric acid concentration and other indicators to reach the international advanced level. It helps to improve the process of fermentation, extraction and crystallization, and creates the world's leading and highest yield “calcium hydroxide + chromatography + continuous dissociation” production process, breaking through the technical barriers of high energy consumption and low yield of the traditional calcium salt method, with the lowest energy consumption in the whole industry. It helps the company to build an international brand of “intelligent manufacturing and smart factory” in the global citric acid industry.
