TCU reactor temperature control system is mainly composed of a heating module, a constant temperature module and a cooling module. These modules work together to meet the complex and changeable temperature requirements in the pharmaceutical process. In the processing and production of drugs, the temperature in the reactor changes with the reaction time. The TCU system can accurately control this change process to ensure that the drugs are subjected to process reactions such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc. under suitable temperature conditions, thereby ensuring the quality and stability of the drugs.

1. The method of changing the control set value can respond to the system lag in the process as quickly as possible and obtain a smaller system overshoot. The control consists of two sets of PID control loops, which are called: main loop and slave loop. The control output of the main loop is used as the set value of the slave loop. By controlling the temperature change gradient in this way, the temperature control accuracy of the system is guaranteed.
2. The specially designed hysteresis predictor generates a dynamic signal yc(t) instead of the process variable y(t) as a feedback signal. Generate an e(t) signal for the controller, so that the controller predicts that the control action has no large lag.

Used with a reactor, it is a special equipment to solve the precise temperature control of the chemical and pharmaceutical industry

• Mlaintainability: the system shall be of good maintainability with a long-term and stable supply of spare parts forcomputers and templates and various sensors and actuators to be used. After our company training, the enterprise canmaintain by itself.
• Scalability: the system is an open system, providing standard TCPlP data communication interface protocol,interfacesoftware and application software interface, with good flexibility and scalability, to meet the requirements of increasingproduction scale for measurement and control ability.
• Security: this system has the authority mechanism, realizes the multilevel authority management, divides five diferentlevels to the operation user, different levels of user operation authority is also diferent. The control system is a relativelyclosed network, and the system network and enterprise LAN or extemal network between the configuration of a firewallcan effectively prevent viruses and network attacks, for the system to operate to create a secure environment.
• Improve the stability of batches: according to the technological reguirement of batch production, establish theappro priate production model and strengthen the management of batches.Through the production batch productionplan designation, produ cion plan distribution and tracking management module, the realization of phammaceuticalproduction batch management.
• Ensure that the integrity of the production data: by applying the computer management system in conformity withthe GlP standard and automatic control svstem, reaize the production of fully automatic data acquisition and monitoringeficient, accurate and complete by the computer system of colle cting and analyzing data processing, are prone to avoidthe traditional manual recording of lagging production data, missing and error.
• Improve traceability of production records: traceability is GMP pharmaceutical producion data, the FDA and othernecessary content of medical industry certification, application of the phammaceutical and pharma ceutical producionauto mation control system intelig ent manufacturing qualtly infomation management system software, the batch numbergoods name, ime, equipment, operators and other pharmaceulical pro duction data in real time, complete and accuraterecords, and implement reverse retrieval process of the production data, can restore all the production status, productionenables producers to analyse the causes of defects of the quality of the products, at the same ime through data tracefunction enables pro ducers to have a better understanding of actual production status, provide data basis for improvethe production.
• Energy saving and environmental protection: the application of production process and infommation managementsystem to pharmaceutical production has a signifcant effect of energy saving, at the same time reduce the intemmediatelink of pharma ceutical production, eliminate the waste of products in the production flow link.
