Plant oil processing

Distiller

A new essential oil distiller has been developed, with good accuracy, exactness and
practicity on loading and unloading, to be used at industrial and research labs.

The device uses electricity to operate, but it can also be adapted to a gas burner for field operations. On this project, we have been seeking for solutions to problems on glass devices. Picture 1 shows the device ready to operate.

Except for the viewer, made of impact-proof glass, the whole device is made of stainless steel 304, with 316 stainless steel on all joints and connections that come in contact with the oil, including the vapor generating electric resistance controlled electronically. These materials grant the destiller great resistance and durability, and low containment rates on the oil.

The inclined condenser of monotubular type has been projected to eliminate all laminar flows, and assembled with a high thermal conductor stainless steel. Those characteristics allow the operation of the equipment with up to 10L/h of cooling water. The low water consumption provides not only economy, but the possibility of using a little raised reservoir for water supply on field experiences, when gas operated.

The vat removable bottom cover can be replaced with an accessory that can extract liquid or semi-liquid materials. Table 1 (at the bottom of the page) compares extractions from the same vegetable materials using the Mini Destiller and a traditional Clevenger apparatus. The greater efficience is due to a better generation, and a higher vapor contact with the tissue, allowed by the architecture of the device.

Operation

The material to be destilled is placed on a 1,7L vat, assembled with a perforateed
removable bottom cover to ease the unload. The vat is removed completely from the device body, allowing faster operation and two-vat usage, in a way to continue destilling in a vat, while loading the other one.

While destilling, the vat is placed over a special flange on the superior part of the
device body, closed with a scape-free cramp that holds all of the vapor inside while
directing it to the condenser.

The condensed product passes through a glass siphon, where the essential oil is separated. The decanted water returns to the device body, closing the cicle. The extracted oil is quantified by level-reading, It can be removed either by the 3-way sphere valve, or by suction from the relief valve.

When electrically operated a safety system controls the electric resistance to the
adequate water level, automatically replacing operational or accidental vapor scape.

Extração de óleos essenciais

Óleo de manjericão:

Linalol e Eugenol O Linalol é usado em larga escala por indústrias de cosméticos e aromáticas. Aproximadamente 70% dos compostos produzidos por essas indústrias contém linalol em sua fórmula. Enquanto produtos populares utilizam o linalol sintético, os produtos mais finos e perfumes utilizam somente o linalol natural, extraído do Pau-rosa.O Pau-rosa é uma árvore que provém de florestas tropicais brasileiras e demora cerca de 30 anos para crescer. Hoje em dia, é a principal fonte de linalol natural.Para proteger as florestas contra devastação, a Lei Ambiental Brasileira considera ilegal o corte de Pau-rosa destinado à extração de linalol.A Linax, por sua vez, extrai o linalol de folhas de manjericão, cultivadas em sistema intensivo, que permite o primeiro corte em apenas 3 a 4 meses do plantio, e produz significante quantidade de folhas 3 vezes por ano, durante aproximadamente 5 anos.O óleo de manjericão é também uma fonte de Eugenol, muito usado em perfumarias e produtos odontológicos.

 

Capacidade de produção:

A Sistema Linax é capaz de produzir 10t de óleo de manjericão num ano, o que resulta em 4 toneladas de linalol e 1 tonelada de eugenol por ano. Esses volumes devem triplicar nos próximos anos.

Empacotamento: Tambores de plástico de 25 litros.

Período de coleta: Novembro à maio: 70% - Junho à outubro: 30%

Óleo de Pimenta-Longa

A Pimenta-Longa é uma planta arbustiva, rústica, muito exigente em luz e água, encontrada com freqüência em áreas de capoeira. Das folhas e dos talos finos é extraído um óleo essencial com alto teor de safrol. O safrol é um componente químico aromático utilizado pela indústria como matéria prima na manufatura de heliotropina (fixador de fragâncias) e butóxido de piperolina (agente sinergístico nos inseticidas e pesticidas naturais à base de Piretrum). Em todo o mundo, o consumo de safrol excede 3 mil toneladas/ano, mas a oferta do produto encontra-se comprometida pela exploração predatória das espécies de que se obtinham o óleo.

Originária da floresta amazônica, a pimenta-longa representa uma fonte alternativa renovável do Safrol. Pesquisas mostram que o óleo extraído da pimenta-longa contém cerca de 90% em safrol.

Fragrances properties influence human behaviors, feelings and emotions. It is being strategically used by food, beverage, cosmetics and perfumery industries.

As the applications and consumption of aromatic substances grows, it opens many
opportunities for essential oils producers; particularly for innovative companies like
Linax.

With a well-planned mix of products, Linax attends different segments of the Essential Oil market, which enables the company to balance its sales and level of activity trough the whole year.

Basil Oil: Linalool and Eugenol

Linalool is largely used by cosmetic and aromatic industries. Approximately 70% of the compounds processed by those industries contain Linalool in their formulaes. While popular and mass dedicated products uses synthetic linalool, high end products and fine perfumes uses natural linalool extracted from Rosewood.

 

Rosewood is a tree that grows in Brazilian Rain forests and takes over 30 years to grow. Nowadays, it is the main source of natural Linalool.

Furthermore, in order to protect forests against devastation, the Brazilian Environmental law considers illegal the cutting down of native Rosewood trees for Linalool extraction.

Linax, however, produces Linalool from Basil plants on an intensive farming system, which allows the first harvest just 3 to 4 months in field and is able to deliver reasonable crops of leaves 3 times in a year for a period of approximately 5 years.

Basil Oil is also a source of Eugenol, which is largely employed by perfumery and dentistry.

Current Production Capacity:

Linax is presently able to supply 12Mt of Basil Oil per year, from cultivated basil leaves, which results in 4 Tons of Linalool and 1 Ton of Eugenol respectively. These volumes are expected to triple in the coming years


Packing: 25-liter plastic drums

Harvest Period: November to May: 70% June to October: 30%

Long pepper oil

Long pepper is an old bush-like plant, very demanding on water and light. From the leaves and thin stems, an essential oil with a high safrole-content can be extracted.

In the chemical industry, safrole is an important raw material, mainly due to two of its derivatives: heliotropin, which is widely used as a fragrance and flavoring agent, and piperonyl butoxide (PBO), a vital ingredient of pyrethroid insecticides.

.

As a fragrance, safrole has many applications in household products such as floor waxes, polishes, soaps, detergents and cleaning agents.

Over the world, safrole comsumption exceeds 3.000 ton/year, but the product offering has been decreasing over years, because of the predatory exploration ocurring on those species which safrole can be extracted.

Long pepper, largely found on Amazon Rain Forest, could be a viable alternative source for safrole. Research has shown that long pepper oil could contain 90% safrole.

Patchouli and Sassafras Oil

The patchouli plant is a bushy herb reaching two or three feet in height. The plant grows well in southern climates. It enjoys hot weather but not direct sunlight. If the plant withers due to lack of watering it will recover well and quickly once it has been watered.

The seed-bearing flowers are very fragrant and bloom in late fall.

.

Patchouli oil has found widespread use in modern industry. It is a component in about a third of modern, high-end perfumes, including more than half of perfumes for men. Patchouli is also an important ingredient in East Asian incense. It is also used as a scent in products like paper towels, laundry detergents, and air fresheners. The essential oil is obtained by steam distillation of the dried leaves of the plant – a process which provides a relatively high yield of the oil.

Votuporanga region bears the widest Rubber Trees cultivated area in Brazil, and the large trees shadows offer very good conditions for Patchouli growing.
