Tube sterilizer
The tubular sterilizer is widely used for products such as milk, juice, tea beverages, and traditional Chinese medicine extracts. This equipment is mainly used for the sterilization and disinfection of various concentrated materials as well as the cooling process. It consists of a material storage tank, a hot water tank, a pump, a tubular heat exchanger, a PLC control system, a control cabinet, a steam inlet system, valves, and induction switches. Features: This machine is suitable for the sterilization and disinfection of various concentrated materials and the cooling process, with a wide range of product viscosity, and can accommodate fibers and particles. It is not prone to coking and has a longer production time. High heat transfer coefficient: The tubular heat exchanger operates in a turbulent state for both the material and the heat transfer medium, resulting in high heat exchange efficiency, reduced scaling, and extended continuous operation time of the sterilizer. It can fully compete with imported equipment. High thermal efficiency: After heating, over 90% of the thermal energy can be recovered. There are no contact points inside the tube, no sanitary dead corners, and products do not adhere to the inside of the tube, making it less prone to scaling. Additionally, the corrugated tube creates a high turbulence during the sterilization process, providing a self-cleaning effect during the material flow, thus preventing the formation of scaling and contamination inside the tube.

Product Description
Tube sterilizer
Usage
Widely used in products such as milk, juice, tea beverages, and traditional Chinese medicine extracts.
Composition
This equipment is mainly used for the sterilization and disinfection of various concentrated materials and the cooling process. It consists of a material storage tank, a hot water tank, a pump, a tubular heat exchanger, a PLC control system, a control cabinet, a steam intake system, valves, induction switches, etc.
Features
This machine is suitable for the sterilization and disinfection of various concentrated materials and the cooling process, with a wide range of product viscosity and the ability to adapt to fibers and particles. It is not easy to form caking and has a longer production time.
High heat transfer coefficient: The tubular heat exchanger operates in a turbulent state for both the material and the heat transfer medium, resulting in high heat exchange efficiency, reduced scaling, and increased continuous working time of the sterilizer. It can fully compete with imported equipment.
High thermal efficiency: After heating the material, over 90% of the thermal energy can be recovered. There are no contact points inside the tube, no sanitary dead corners, and the product does not adhere to the inside of the tube, making it less prone to scaling. The corrugated tube creates a high turbulence during the sterilization process, providing a self-cleaning effect during the material flow, thus making it less likely to form scaling and contamination inside the tube.
Compact structure, good sterilization effect, easy operation, and wide adaptability.
Working Principle
The device uses Siemens PLC for fully automatic control, with automatic control of sterilization temperature and automatic recording; backflow valve action status, high-temperature alarm, low-temperature backflow (automatic); cleaning status, equipped with a CIP cleaning system. It is a jacketed type, mainly designed for traditional Chinese medicine concentrated liquids and high-viscosity materials. The heat exchange tube uses corrugated tubes, which create turbulence during the flow of materials, allowing for self-cleaning. The material flows inside the tube while the heating or cooling medium flows outside, thus heating or cooling the material.
Working Process
Sterilization: The device is mainly divided into five sections. The first section is the heating section, using superheated water as the heating medium to heat the material to the sterilization temperature, which can be set (85℃ to 137℃). A temperature detection is set at the heating terminal; if the temperature does not reach the sterilization temperature, the backflow valve is opened in advance, and the material flows back to the material balance tank for secondary sterilization. The second section is the insulation section, where the material continues to be sterilized at a constant temperature after reaching the sterilization temperature. The third section is the preheating utilization section, where the heat from the material is used to heat the hot water after sterilization for energy recovery. The fourth section is the initial cooling section, which uses cooling water for preliminary cooling. The fifth section is the deep cooling section, which uses chilled water to cool the material to the set temperature. If the outlet material temperature requirement is high (above 40℃), the fourth and fifth sections can be combined to use cooling water for cooling.
Cleaning: After each shift or if a significant decline in sterilization effect is observed, the equipment should be cleaned. Switch the working mode on the control interface to cleaning mode, inject water into the material buffer tank, and start the cleaning pump for high-flow, high-pressure circulation to flush the heat exchange tube until clean. The two ends of the "U"-shaped pipe joint can be disassembled to check the cleaning effect. If any structure is found, acid or alkali should be used for cleaning. After cleaning, the accumulated water inside should be drained.
Heating: Heating is done by mixing steam and hot water to create superheated water, using superheated water as the heating medium. Pressure reduction is done using a Spirex pressure reducing valve, and temperature control is done using a Spirex pneumatic diaphragm regulating valve.
Cooling: Cooling is done using cooling water and chilled water. The specific choice of cooling medium is related to the temperature of the outlet material, selected based on energy-saving principles.
