Reactor de plasma no térmico para esterilización de especias


Oferta Tecnológica
Un equipo de científicos polacos ha desarrollado un reactor de plasma no térmico para esterilización de productos orgánicos. Se trata de una solución que puede aplicarse en el campo de producción de especias. La tecnología permite modificar parámetros, de manera que la generación de plasma no térmico es flexible y puede incrementarse su aplicación. Se buscan productores de especias con el fin de establecer acuerdos de licencia.


Non-thermal plasma reactor for spices sterilization is offered
A group of Polish scientists have developed non-thermal plasma reactor for organic products sterilization. It is a solution that can be applied in spices production while products available on the market are not sterile.

The offered technology allows to modify parameters therefore non-thermal plasma generation is flexible which increases its use.

Scientists are interested in starting cooperation with spices manufacturers under the license agreement.
Polish scientists have developed solution applicable for sterilization of spices, based on usage of non-thermal plasma.

The spices which are commercially available are not sterile. The offered solution allows to decrease the amount of bacteria in the product or even minimize it to the detection level. It is possible thanks to the use of non-thermal plasma reactor. Till now this method was not so popular in food industry because of reactor construction and optimization of the whole process. The reason of this is the fact that during the discharge process a smooth change of the position of the electrode in relation to the product was not possible. The mutual change of the position of the electrodes and the batch has a significant impact on the quality and the effectiveness of the sterilization process. The reactor constructed by the team of scientists allows to generate plasma in gas environment between movable plates which are powered by high voltage. Thanks to easy modification parameters of power supply the whole process of plasma generation in flexible which means that it can be used to sterilization of products with different structure, density and thickness of layers.

The reactor is equipped with a chamber, a base, on which a housing is placed, a grounding lower and an upper electrode. It characterizes in that it has a mobile multi-needle upper electrode connected via insulators with its sliding mechanism which is placed on the base on the bottom insulators. The upper electrode is placed on an insulated mobile platform and is joined with electrical culvert with high potential. The reactor has power of 0 to 350 W and voltage of 0 to 30 kV.

The team of West-Pomeranian scientist has developed the non-thermal plasma reactor in cooperation with business. As the solution is working and ready for implementation it is available under license agreement where scientists transfer rights to use it in return for a fee. They are interested is cooperation with spices manufacturers.
Advantages and Innovations:
The invention allows to carry out the sterilization process of organic products in a very flexible way. First of all, the space between the electrodes is adjustable with respect to the sterilized product (e.g. different kinds of spices), and appropriate parameters of power, voltage, and time can be selected. Furthermore, this solution allows to optimize the process by taking into account the thickness of the sterilized product, and hence its structure and density. Previous solutions gave no chance to change location of the electrode in relation to the sterilized product.
Stage of Development:
Available for demonstration
Patent(s) applied for but not yet granted
CommeR Statunts Regarding IPR Status:
Scientists applied for European and Polish patent protection.
