UHT Pilot Plant

The UHT pilot plant is composed of the hot water system, ingredients dissolving system, blending or fermentation system, pilot UHT sterilizer, mini homogenizer, aseptic filler, operating platform, and auxiliary system(air compressor, chiller and RO water system).

The capacity of the UHT pilot plant is from 20L/H, 50L/H and 100L/H available to choose from.

The whole system is designed with an integrated, compact structure, that can save space and move flexibly.

It is controlled by PLC, with a high degree of automation, and simple operation.

The UHT pilot plant is also equipped with data record control system, which can record various experiment data, download data, online printing and generate the analysis curve. The complete data recording system will greatly help guide industrial production and teaching purposes in college.

The pilot UHT sterilizer is built with hot water generating system, can be connected with a homogenizer and aseptic filler to make the aseptic products.

The independence of some stand-alone equipment can be used in production lines or independently without the need for additional facilities.

The main structure is made of high-quality 304 stainless steel and 316L stainless steel.

The whole system can be used for beverages, juice, tea drinks, plant-based drinks, milk, dairy products formulation testing, beverage processing technology verification and flavor testing: Ingredients formulation, UHT sterilizing, homogenizing process testing, aseptic filling, hot filling, cold filling products shelf life testing, testing for sequence of adding small ingredients, mixing temperature, stirring and emulsification time, flavor test after ingredients, homogenization temperature and pressure, sterilization temperature and time, filling temperature, etc.

It is widely used in teaching and demonstration purposes in universities and colleges; It can also be used in food and beverage enterprises for new product development and production, new product taste testing, product formula research, formula update, product color evaluation, shelf life testing, etc.

This whole system is composed of hot water tank, High shear emulsification tank and blending tank, products pumps, water pumps, pipelines and connecting valves.

The hot water is heated by electricity, and the hot water tank is polished inside and outside, with built-in heating tubes, float type liquid level gauge, upper flat cover and bottom elliptical head, SUS304 material.

The high shear dissolving tank is a jacketed tank heated by hot water, with top emulsifying head stirring, top opening cover, liquid level sensor and temperature sensor, and sight glass.

The blending tank is also a jacketed tank, eccentric vertical mixing, CIP cleaning port, sample valve, electrode type level sensor, and temperature display.

The pilot UHT sterilizer is the core machine in the UHT pilot plant. It is widely used in liquid foods such as juice drinks, tea drinks, fresh milk and yogurt, and juice with fibers and particles.

It includes a tubular heat exchanger, machine frame, balance tank, material pump, built-in hot water system, and electronic control system. When running, there is no need steam boiler and RO water treatment system.

Various sterilizing process: 25℃material inlet–65℃homogenizing—85-95℃/115℃/121℃/137℃ holding for 5S/10S/15S/60S/120S/300S sterilizing–5℃/25℃/85℃ material outlet.

Material feeding and discharging is automatic, sterilizing temperature and time automatic control and adjustable.

The whole system is made of SUS304/316L with an online CIP system, easy to clean and ensures hygienic condition.

Capacity is from 20L to 100L to choose from.

The homogenizer and aseptic filling chamber can be configured according to actual research and development needs. The aseptic filling chamber can adapt to a variety of packaging containers.

Good safety protection, the heat exchange tube is equipped with an insulation layer and a rack-mounted protective net to prevent operators from being burned.

The pilot UHT sterilizer can do the heat treatment of material viscosity less than 6000cP, and the material particle size less than 2mm.

The sterilization temperature is strictly controlled. When the sterilization temperature is lower than the set lower limit, the timer will terminate and reset to strictly ensure the sterilization effect of the equipment.

This equipment is a vertical flow-shaped sterile operating table and an air purification system composed of a fan, primary effect, high-efficiency filter and ion generator.

When working, the outside air is pre-filtered by the primary filter, and then sent to the high-efficiency filter by the fan to reach high ultra-cleanliness (level 100) in the operating area. Finally, it is sterilized by the ultraviolet lamp and ion generator to form an ultra-clean environment locally.

The working unit is independent; the foot switch controls the filling switch, and the operation is completely matched with the UHT system.

The built-in product buffer tank is equipped with a single-head pneumatic filling valve; the built-in automatic capping device is optional for batch production of samples.
