Kjeldahl is a widely used instrument for measuring nitrogen and protein in industries such as food feed, soil, and wastewater. The digester is an important part of it, but currently many digestion furnaces only have temperature control and no program temperature-raising function. In the whole digestion process, it is necessary to artificially adjust the temperature several times, which also leads to relatively cumbersome operation of the Kjeldahl apparatus. With the development of science and technology, especially the development of intelligent control technology, the realization of intelligent temperature-controlled digestion furnace has become an important goal to improve the performance of the Kjeldahl nitrogen analyzer.
One of the greatest benefits of intelligent temperature-controlled digestion ovens is the ability to integrate program warming, automate digestion, and save manpower and time. Compared with the traditional digestion furnace, the intelligent temperature-controlled digestion furnace has the advantage that the digestion process adopts a program to raise the temperature, different heating rates are adopted for different substances, and the temperature of the digestion tube is evened during the entire digestion process, which is favorable for stable digestion. Not easy to spray or splash. Therefore, it can effectively prevent the overflow of digestive products and realize the automation of the digestion process. The instrument has high control accuracy, saves manpower, and has an over-temperature and burn-out alarm. Problems can be discovered immediately.
To reflect the superior performance of the intelligent temperature-controlled digestion furnace, the temperature control system is required to ensure that the digester changes according to the specified temperature curve, with little overshoot or overshoot, good stability, and no oscillation, but in general, the intelligent temperature Controlled digestion furnaces have low requirements for the rapidity of the system. At the same time, whether it is for the intelligent temperature-controlled digestion furnace design or for other instrument design, from the design to the application process, we must proceed from reality. The digestion furnace may need to consider technical indicators, the use of environmental requirements, etc. The main purpose is To ensure that the intelligent temperature-controlled digestion furnace can meet the needs of the actual sample digestion work, solve the actual problems encountered in the current work, and truly play a role in alleviating the pressure on the staff and improving the safety performance and accuracy of the instrument.
