Turbular Uht High Temperature Short Time Sterilizer

Tubular ultra-high temperature sterilizer is an indirect continuous ultra-high temperature instantaneous sterilization equipment. Materials flow inside Stainless steel tubes, exchanging heat with superheated water in the jacket through tube walls to realize continuous UHT sterilization under sealed conditions. It is mainly used for commercially sterile treatment of liquid food containing particles or with high viscosity.

PRODUCT DESCRIPTION

Description 

The tubular UHT sterilizer is an efficient ultra-high temperature instant sterilization equipment, designed for continuous processing of thin liquid food and beverage products.

Fabricated from food-grade SUS304/SUS316L stainless steel, it delivers reliable UHT sterilization with precise temperature control, automatic low-temperature recirculation and full CIP cleaning support, enabling hygienic closed-loop production.

Work Principle

General material is pumped by centrifugal pump into the sterilizer in the hot and cold material heat exchange device and get preheated, and then through the high temperature barrel filled with high pressure, the material is rapidly heated to the sterilization temperature and kept about 3 seconds after the previous, in which the microorganisms and enzymes are quickly killed. Material out of the high-temperature barrel through the heat exchange with the cold material to obtain cooling, the general temperature is below 65 ℃. If the next process needs to increase the temperature can be adjusted through the angle shut-off valve or circulation and other ways to achieve the requirements, and vice versa through the access to cooling water to reduce the temperature of the discharge. The discharge is controlled by a throttle valve, which enables the boiling point of the material to be maintained at a certain pressure above the maximum temperature. Adjust this valve during normal production, by the pump's driving force to overcome the spring pressure and generate back pressure to control the flow, in the cleaning of the sterilizer should be fully open. Circulation tank can be used to prepare acid and alkali solution, the coil wall scale buildup for effective cleaning. Due to the simultaneous use of Stainless steel three-way plug, the flow rate can be properly

adjusted.

System Composition

1. Balance tank: Stabilize feed and buffer liquid level

2. Feed pump (centrifugal pump / rotary lobe pump; rotary lobe pump for high-viscosity materials)

3. Tubular heat exchange unit (double-tube / multi-tube type)

4. Holding tube (determines holding time, core process component)

5. Hot water circulation system (steam + superheated water heat exchanger)

6. PLC & HMI automatic control system, temperature/pressure transmitters, return valve (automatic return if temperature fails to meet standard)

7. CIP (Clean-in-Place) + SIP (Sterilize-in-Place) module, complying with food GMP, 3A and FDA sanitary requirements

Material contact surface: 316L stainless steel with mirror polish, free of rubber gaskets, which is one of the biggest differences from plate UHT.

Features

1. Compact and small footprint: 
The unit is compact with a space-saving design.

2. Easy cleaning with CIP system: 
Cleaning is easy and can be carried out using the Cleaning-in-Place (CIP) system without dismantling 

3. Safe and user-friendly operation: 
The unit ensures safe use with easy-to-operate controls.

4.PLC Remote Access Layer: Provides stable and reliable remote connections, offering the underlying technical support for program transfer and monitoring, breaking down spatial barriers.

 
5.Real-Time Data Service Layer: Handles the real-time collection, transmission, and display of equipment data, and exposes remote setting capabilities via Web/APP interfaces.
 
6.Intelligent Alert Routing Layer: Contains decision-making logic to intelligently distribute different levels of equipment events to the optimal notification channels like SMS and WhatsApp.
 
7.Time-Series Data Storage & Analytics Layer: Responsible for the compressed storage and fast retrieval of massive historical data,and provides a rich set of visual components.
 
8.Data Analysis & Decision Support Layer: Models and statistics core data such as energy consumption and failures, outputting meaningful analytical conclusions for guidance.

Application

UHT milk, formulated milk, cream, soy milk, oat milk; fruit juice with pulp, fruit pulp, jam; tomato paste, condiment sauces; protein drinks, ice cream mix, liquid seasonings; also applicable to sterilization of some pharmaceutical fluid materials. Capacity: Normally 1~20 t/h; large models up to 40 t/h.

Key Advantages

·  Suitable for materials with fruit pulp/fiber/fine particles and high viscosity (fruit juice with pulp, fruit puree, tomato paste, condensed milk, sauces, protein beverages), less prone to blockage; plate UHT cannot handle particle-containing materials.

· High pressure resistance, long continuous operation, slower fouling rate. Production cycle can reach 12–24 hours before CIP cleaning.

· No plate gaskets, no risk of gasket aging, leakage or contamination.

· Gentle shear on materials, less damage to suspended particles and emulsion stability.

· Full automatic interlock protection: low-temperature return, over-temperature/low-pressure alarm, production data recording.

Tubular UHT VS Plate UHT

FAQ

Q1: What products can the tubular UHT sterilizer process?

A1: It is suitable for continuous sterilization of thin liquid food and beverages, and can also handle medium/high-viscosity materials and liquids containing fine particles, such as UHT milk, plant-based drinks, fruit juice with pulp, fruit puree, tomato paste and sauces.

Q2: What material is the machine made of?

A2: Food-grade SUS304 or SUS316L stainless steel for all product contact surfaces, complying with food hygiene standards.

Q3: What is the sterilization temperature and holding time?

A3: Standard UHT condition: 135–150°C, holding time 2–15 seconds, adjustable via PLC according to different products.

Q4: Does it support automatic cleaning?

A4: Yes. The machine is equipped with full CIP (Clean-in-Place) function. SIP pre-sterilization of the whole pipeline is available before production startup.

Q5: What will happen if the sterilization temperature is insufficient?

A5: The system will trigger automatic low-temperature recirculation. Unqualified material flows back to the balance tank and will not enter the aseptic filling section.

Q6: What are its advantages compared with plate-type UHT sterilizer?

A6: No rubber gaskets, lower contamination risk; resistant to particles and high viscosity, less fouling and longer continuous running time.

Q7: What utilities are required?

A7: Steam, cooling water, chilled water (optional) and 380V power supply.

Q8: Can the equipment be customized by capacity?

A8: Yes. We can design machines with different hourly throughput from 1 t/h up to 40 t/h based on customer requirements.
