Description

DESCRIÇÃO "MÉTODO DE EXTRACÇÃO SÓLIDO-LÍQUIDO APLICADO A PRODUTOS DE CORTIÇA"DESCRIPTION " SOLID-LIQUID EXTRACTION METHOD APPLIED TO CORK PRODUCTS "

1 - OBJECTO DE INVENÇÃO A invenção refere-se à descontaminação de produtos de cortiça por meio de um método de extracção sólido-líquido com base na aplicação sucessiva de alterações de pressão sobre uma superfície de líquido no qual a cortiça é imersa, que provoca a contracção e expansão de cortiça, provocando assim a libertação de contaminantes retidos no interior da cortiça.OBJECT OF THE INVENTION The invention relates to the decontamination of cork products by means of a solid-liquid extraction method based on the successive application of pressure changes on a surface of liquid in which the cork is immersed, which causes the contraction and expansion of cork, thus causing the release of contaminants retained inside the cork.

2 - ESTADO DA TÉCNICA A cortiça é um produto poroso natural que contém, na sua superfície e no seu interior, uma variedade de contaminantes derivados da sua vivência na floresta que, quando em contacto com líquidos, podem provocar alterações organolépticas nesses líquidos.2 - STATE OF THE ART Cork is a natural porous product which contains, on its surface and inside, a variety of contaminants derived from its experience in the forest, which, when in contact with liquids, can cause organoleptic changes in these liquids.

Durante os últimos anos, têm sido desenvolvidos e aplicados vários métodos numa tentativa de eliminar os referidos contaminantes. Os métodos existentes são baseados na imersão de cortiça em banhos de desinfectante, alternados com passos de centrifugação. Devido às condições de funcionamento, estes métodos não eliminam todos os contaminantes, nomeadamente 1 aqueles que estão retidos no interior de cortiça que podem, subsequentemente, oriqinar alterações organolépticas nos líquidos com que o produto de cortiça contacta.During the past few years several methods have been developed and applied in an attempt to eliminate such contaminants. The existing methods are based on the immersion of cork in disinfectant baths, alternated with centrifugation steps. Due to the operating conditions, these methods do not eliminate all contaminants, namely those which are retained inside cork which may subsequently originate organoleptic changes in the liquids with which the cork product contacts.

Em 1993, foi patenteado (Documento PT 101215 de 1993.03.11) um processo termodinâmico para a expansão de cortiça utilizando um sistema pressurizado (pressão relativa de 9,8 a 29,4 bares) em que a cortiça é imersa na presença de alguns solventes orgânicos, nomeadamente, metanol, etanol, ácido fórmico, diclorometano ou clorofórmio.In 1993, a thermodynamic process for the expansion of cork was patented (Document PT 101215 of 1993.03.11) using a pressurized system (relative pressure of 9.8 to 29.4 bar) in which the cork is immersed in the presence of some solvents organic, in particular methanol, ethanol, formic acid, dichloromethane or chloroform.

Apesar de algumas características da patente acima serem semelhantes às da presente invenção, a sua matéria é diferente, bem como os seus objectivos para atingir a expansão de material de cortiça, que não estão relacionados com descontaminação.While some features of the above patent are similar to those of the present invention, their subject matter is different, as well as their objects to achieve the expansion of cork material, which are not related to decontamination.

Verificou-se que a água é um liquido apropriado para ser utilizado no processo de descontaminação, o que constitui uma vantagem com vista à sua disponibilidade, com uma redução substancial no custo final do processo de descontaminação.It has been found that water is an appropriate liquid for use in the decontamination process, which is an advantage in view of its availability, with a substantial reduction in the final cost of the decontamination process.

3 - DESCRIÇÃO PORMENORIZADA DA INVENÇÃO A requerente verificou que este problema de descontaminação incompleta de produtos de cortiça podia ser resolvido através de um método hidrodinâmico, através do qual a cortiça a ser tratada é colocada num recipiente hermético e, subsequentemente, imersa em água que deve ser colocada a uma temperatura que varia de 20 °C a 200 aC. 2DETAILED DESCRIPTION OF THE INVENTION The applicant has found that this problem of incomplete decontamination of cork products could be solved by a hydrodynamic method whereby the cork to be treated is placed in an airtight container and subsequently immersed in water which must be placed at a temperature ranging from 20 ° C to 200 ° C. 2

Depois aplica-se uma pressão relativa até 10 bar na superfície do líquido, durante 1 a 3600 segundos, utilizando qualquer tipo de gás ou mistura de gases. Em seguida, o gás é libertado até a pressão do recipiente atingir de novo a pressão atmosférica. Depois disso, a pressão é reduzida por meio de uma bomba de vácuo adequada até ser atingida uma pressão relativa até -1 bar. Após permanência sob esta pressão reduzida durante 1 a 3600 segundos, o sistema é recolocado à pressão atmosférica.Then a relative pressure of up to 10 bar is applied to the surface of the liquid for 1 to 3600 seconds, using any kind of gas or gas mixture. Thereafter, the gas is released until the pressure in the vessel reaches atmospheric pressure again. Thereafter the pressure is reduced by means of a suitable vacuum pump until a relative pressure of up to -1 bar is reached. After standing under this reduced pressure for 1 to 3600 seconds, the system is replaced at atmospheric pressure.

Estes ciclos de pressão diferencial são repetidos várias vezes até que o grau de pureza de cortiça desejado seja atingido. Uma experiência simples define o número de ciclos necessários.These differential pressure cycles are repeated several times until the desired degree of purity of cork is reached. A simple experiment defines the number of cycles required.

Os especialistas na técnica compreenderão que podem ser feitas alterações ao método da invenção, que devem ser entendidas, como estando incluídas no âmbito das reivindicações anexas.Those skilled in the art will appreciate that changes may be made to the method of the invention, which are to be understood as falling within the scope of the appended claims.
