Torrified wood

It can crumble more easily, depending on the wood species. However, this strength reduction is not very significant for most wood species. It quickly turns new wood into what naturally takes decades, saving a lifetime of waiting for an instrument to finally get that aged tone. Torrified (also spelled “ torrefied” ) wood neither swells up during humid summer months nor dries out due to dry winter air. Torrefaction of biomass, e. Roasted wood is wood that has been thermally modified at high temperatures, often through a secondary kiln process.

Torrified wood has been heat treated or roasted until it has nearly internal moisture. Roasted wood , sometimes called thermally treate tempered vulcanized or torrefie is ideal for environments with high or varying moisture levels. Of course, traditionally dried woods also acclimate to their environment.

Without oxygen, the wood itself can’t combust. The gases coming off the wood combust. If you heat it long enough, it becomes charcoal. What does torrefied mean?

Our torrefied doors undergo an all-natural green process to eliminate wood’s tendency to rot. It also makes the door far more structurally stable, and highly resistant to heat, cold and moisture. Not only does a torrefied top offer greater stability and tone, the thermo-curing process dramatically speeds up the natural aging of wood that in a vintage-looking, golden-caramel hue.

Some of you may have already had a precursory introduction to the process and perceived benefits of wood torrefaction (also sometimes called “thermo-curing”) in relation to guitar building. Biomass torrefaction is a thermal process used to produce high-grade solid biofuels from various streams of woody biomass or agro residues. The end product is a stable, homogeneous, high quality solid biofuel with far greater energy density and calorific value than the original feedstock, providing significant benefits in logistics, handling and storage, as well as opening up a wide range of potential uses. The term torrefied wood refers to wood that has undergone a drying process.

From Peter Schu with Dana Bourgeois: “Every acoustic guitar top must be dry, stiff and lightweight. For centuries, luthiers chased this holy trinity of adjectives with various methods of carving, bracing, and drying with air or kilns. Apart from having many similarities to coal, it is still renewable energy and believed to replace many types of biomass within the years to come.

Densified torrefied biomass has several advantages, which makes it a competitive option in different markets compared to conventional biomass. Hydroscopic cellulose is sealed so wood resists warp and movement. The definition of torrefy is simply to dry or roast with fire. That’s exactly what torrefied wood is: wood that has been heated over a long period of time within a controlled atmosphere. Another term commonly used to describe wood that has been treated this way is thermally modified.

In this way , the temperature of the timber is raised by means of heat and steam to 1° C and then gradually up to 1° C. A torrefied wood pellet repels moisture. Therefore they address one of the key issues with current wood pellet fuel. They also produce no smell, Ho visible smoke and contain a much higher energy content than current pellet fuels.

True torrefaction—the elimination of volatiles without damaging structural cellulose—occurs within a range of temperature and duration of treatment that varies from one wood species to the next. The window for optimum treatment is relatively narrow, but within it, different degrees of aging can be simulated. I’ve experimented with torrefied woods that appear to simulate between and 100. These two products can pass for identical twins to the average consumer, but really they are only fraternal twins (like me!).

With a black surface and higher energy density, it is likely called man made coal or bio coal. Then, what’s torrefied wood pellets and how’s it made? This time, it is called torrefied wood.

It is a technology that has been around for a while, but has only recently been applied to the crafting of musical instruments, and I am the first to apply it to the inner workings of the banjo. In the th century the Vikings torrefied the wood they used to build their ships, enhancing its stability and durability. The wood is gradually pre-heated in a conventional kiln lowering the moisture content to between and.

Blackwood is selling torrefied pellets produced in our industrial scale demo plant. Tempered Tonewoods creates the most resonant tonewood for guitars, basses and other musical instruments. The torrefication process involves carefully heat-treating the wood in an oxygen-free kiln.

The wood actually changes at the molecular level—the end result is new wood that has the same cell structure of well-aged decades-old wood. The change is notable: builders have reported improved tap tone, greater strength, and lighter weight.
