It is rolled from the whole plate，with no welding seam in the middle and all automatic welding has no damage to the plate. and will not cause perforation or internal leakage of the plate
Sealing strips at both ends of the heat exchanger are beveled to ensure penetration and reduce stress. Release stress from inside and outside during welding After welding is completed, stress is released through vibration treatment to avoid leakage.

Make full use of latent heat of vaporization of steam, with compact structure,small resistance and no vibration; Special flow channel size high flow rate design and appropriate cleaning scheme can prevent the material from remaining due to the long-term operation of particles in the material;The special structure ensures uniform heating, preventing coking and scaling caused by excessively high local temperatures of materials; For special materials, an ultrasonic descaling device is added at the material inlet.

Special runner size is selected，on-line cleaning is carried out the structure is compact，no dead comers of materials exist,the resistance is small, no scaling,no coking matter and no material adhesion are realized

Siemens S7-1200PLC control system is adopted and the touch screen is equipped to facilitate on-site control. The intelligent system can multi-point sample the temperature, pressure and flow value of equipment with a sampling period of 200 ms. The system judges all temperature, pressure, flow signals and takes corresponding measures. For high-risk alarms, the system forcibly interrupts the process and switches to the safety mode.The system supports ODBC/SQL standard databases and can provide OPC, DP, and MODBUS interfaces. It can act as a server or a client. When necessary, it can provide parameters such as protocols and can be connected to the main DCS control system of the fermentation workshop for control.
