SteriBeam Systems – PUV and PEF Sterilisation and Nutrient Extraction-Enrichment Systems

SteriBeam Systems designs and manufactures standard and customised pulsed UV (PUV) and pulsed electrical fields (PEF) sterilisation systems. Its facilities are equipped with modern process diagnostic tools and its systems are made through partnerships with established local manufacturing companies.

Bench-top PUV, PEF and Cold Plasma systems

The standard product line includes fully and semi-automatic bench-top PUV and PEF systems, which are suitable for many applications. PUV systems can be used to sterilise various packaging, surfaces of foods and juices, nutrition powders, and they can also sterilise surfaces for foods or pharmaceutical solutions through some clear packaging materials.

PEF systems can be used for the sterilisation of juices and various food and medical solutions, plus they can extract nutrients, natural colours and juices from roots, grass and the skins of fruits and vegetables.

SteriBeam's cold plasma system (their customised variation of the PEF system, same enclosure), uses 2.45 GHz MW pulsing between two electrodes in a process chamber with a low pressure (a few Torr, or a few hundred Pa). This condition creates a cold plasma where its ions and electrons sterilise various surfaces (e.g. of medical devices).

Its main advantage to PUV or PEF sterilisation: cold plasma also removes de-activated micro-organisms from surfaces (including rests of DNA), it all just pumped out.

Disadvantage: it works only at a very low pressure.

Bench-top fully automated PUV sterilization system

The XeMaticA-2LFA is a fully automated PUV bench-top system. It has a medical-grade stainless-steel housing and is ozone and IR free. The chamber door is automatically locked during the system operational cycle to ensure that no UV or EM fields leak out.

The XeMaticA-2LFA PUV system is an ideal R&D tool for food, medical and pharmaceutical applications. It offers an easy-to-use touch-screen selection of:

• 180° or 360° product exposure by operating one or both lamps
• Pulse energies: 100J to 500J
• Illuminated sample surface: 5x20 cm, or 10x20cm or 20x20cm with changeable reflectors
• Interactive LCD display
• Water cooled lamps remove heat (IR) and Ozone
• Pulse repetition rates: 0.5Hz-5Hz
• Number of pulses per treatment cycle (pulse bursts): 1-100
• Changeable distance between lamps and sample shelf
• Optional filters to remove 90% of the visible and the rest of IR light

Bench-top semi-automated PUV sterilization system

The semi-automated XeMaticA-SA-1L is a bench-top PUV system with one PUV lamp that operates as an R&D tool for food, medical and pharmaceutical UV tasks. Its features include:

• Pulse energies: 100J to 1,000J
• analogue controls
• 270° product exposure,
• Changeable distance between lamps and sample shelf
• Optional filters to remove 90% of the visible and the rest of IR light
• Illuminated sample surface: 5x20 cm, or 10x20cm or 20x20cm with changeable reflectors

Bench-top fully automated PEF sterilisation system

SteriBeam Systems' fully automated PEF (pulsed electrical fields) bench-top systems are available in our standard operational voltages: 5kV-30kV or (custom) 40kV-80kV. Features include:

• Pulse durations: 1µsec - 100µsec
• Pulse energies: 5J- 50J
• Repetition rates: 1Hz-100Hz (limited by power for each selected energy)
• Standard power output: 500-2000 w (custom: up to 30 kw)
• Pulse bursts: 1-1000 pulses / exposure or a continuous operation (in line).

Bench-top semi or full automated cold plasma sterilisation system

Thier cold plasma system (a customised variation of the PEF system), uses the same enclosure, operated with 2.45 GHz MW pulsing between two electrodes in a process chamber with a low pressure (a few Torr, or a few hundred Pa). This condition creates a cold plasma where its ions and electrons sterilise various surfaces (e.g. of medical devices). Standard features include analogue controls for:

• Regulated MW power deposition: 50-500 w
• Timer: 1-10 min
• Pressure: 0.1-200 Torr
• Gas filling: outside gas choice for to fill-in with a flow-meter, or using an air flow

Other features:

• Shelf for products (Pyrex),
• The chamber size: diameter 20 cm, 30 cm long, front door has a net shielded quartz window. The chamber can be also 20x20 cm front and 30 cm deep.
• Interlocks (the door is locked during processing cycles).

Pilot and production UV sterilisation systems for powders

Their UV sterilisation system for powders can be used for nutrient powders, for shred organic products Teas, spices, small seeds, etc. It consists of a powder advancing device, UV treatment chamber, sub-system for moving powder around the UV source, powder releasing device.

They offer labour (10-50 kg/hr) and production (100-1,000kg/hr) sterilisation systems for powders. Larger systems can be designed and constructed on order as custom systems.

Choices of lamps: Continuously operation 254 nm lamps or PUV lamps.

Pilot and production PUV sterilisation tunnels

They manufacture UV tunnels with intense pulsed UV lamps for the sterilisation of food and packaging on a conveyer with a throughput to 1000 products/h. SteriBeam have a standard PUV Tunnel, where they can design a tunnel to a customer spec.

Applications of their PUV sterilisation tunnels include:

• External surfaces of packaging
• All round surfaces of packaging and content of packaged products if they are transparent to UV light (if not, they will recommend UV transparent packaging materials),
• Sterilisation of pharmaceutical solutions (e.g. saline) already filled in transparent (non labelled) packaging.

Evaluation trails are welcomed at their cooperating bio-lab. In some cases outside rentals are available.
