  • November 2012

Arauco again relies on MAHILD to train 20 of its employees from different sawmills. Specifically, this involved a course on advanced lumber drying. In total there were 4 days of lessons and the course was attended by the heads of the divisional managers responsible for process improvement and the associated mechanical drying process. The course includes training on various topics that occur in the drying process, such as: application of the Fourier and Heisler equations for heating and cooling, drying time model by convective mass transfer, thermal performance by psychrometric model and thermal energy model.

  • November 2011

Arauco, the largest Chilean forestry company chose MAHILD in order to train 30 of their employees from different sawmills. It was a training course for operators of high-tech drying. In total there were 8 days of classes and participating were kiln assistants, operators, supervisors and department heads.

The course included a comprehensive training that involved different topics present in the drying process, such as anatomical knowledge of wood, wood physics, thermodynamics and Psychrometry, heat and moisture transfer, best practices of filleting and charges, schedule creation, degradation and ways to reduce, control system operation, engineering notions of drying, drying of Eucalyptus and thermally modified wood.

The feedback of the participants was very positive and planning was made for an advanced course of drying to be performed by MAHILD in a couple of months.

TMT IHD

Description of pilot-scale thermo-kiln of IHD

  • August 2011

The thermo-kiln of IHD (fig. 1) allows to manufacture thermally modified timber (TMT) in a pilot-plant scale by defined conditions. The kiln of type MAHILD MH 2000 TMT is configured for thermal treatment under normal pressure at temperatures up to 250 °C. For distinct process steps, steam can be added. Staple size is up to 1200 mm length; the usable volume is of about 0.5 m³. The optimal cross-section is 650x650 mm², the maximum 900 mm width and 800 mm height. The kiln can be used as conventional kiln dryer, too, with controlled supply and exhaust air valves. With a special technology, applied for patent in Germany in 2010, it is possible to treat plane materials, like veneers or panels, with a high quality. This kiln is controlled by PC (fig. 2) and SPS with software MM 4000. The process steps and a lot of parameters are freely programmable; a typical run is shown in fig. 3. Control factors for the thermal modification are kiln and wood temperature, respectively, for kiln drying this is air temperature and air humidity. Relative air humidity is measured by psychrometers, the wood moisture by electrical resistance method. The wetting, e. g. for cooling down, is done by water spray. For a uniform flow, the fan can be operated in a forward-reverse mode, controlled by a be frequency converter.

Mahild Lumber Dry Kiln Red Stag Timber

Red Stag Timber

  • August 2011

A Red Stag Timber em Rotorua encomendou esta semana a primeira câmara de contrafluxo contínuo operacional da Nova Zelândia. A capacidade das câmaras é de 100.000m³ de madeira seca por ano. Em vez dos desenhos e funcionamento mais tradicionais da câmara, o CONTRAFLOW Mahild de 60 metros de via dupla utiliza duas vias dentro da câmara. O calor da pilha de saída quente seca é usado para pré-condicionar a madeira verde que entra na câmara e a umidade da secagem da madeira verde também é usada para recondicionar a madeira seca que sai da câmara.

Esta nova câmara de secagem irá reduzir significativamente a energia necessária para secar a madeira e faz parte do esforço da Red Stag para melhorar a eficiência e a qualidade do produto. O gerente do câmaras de secagem, Steve Goldsmith, diz que está extremamente satisfeito com a qualidade da madeira serrada que sai desta nova câmara Mahild.

Mahild Lumber Dry Kiln James Jones

James Jones

  • February 2011

James Jones & Sons Ltd is investing in a further six kilns from Mahild in a move which will boost annual kilning capacity at its Steven's Croft mill operation at Lockerbie to 160,000m³. The latest move at the site will take the group’s total number of kilns to 16. The new units are expected to come on stream during October and reflect the growing volumes being processed through the new sawline at the Lockerbie 3 mill. Existing kilns at the site are fitted with a heat recovery system and have already successfully reduced energy consumption. The kilning complex is being heated with hot water provided by the neighbouring Eon biomass power plant and conveyed by a pipeline installed in 2010. James Jones said the system saves an estimated 9,000 tonnes of carbon emissions annually.

Mahild reduces drying energy

Mahild reduces drying energy

  • July 2009

The key focus for kiln specialist Mahild was its latest developments for cutting energy used in drying timber. The newest technology highlighted was the latest generation of its ECO-VENT system, ECO-VENT III. This uses exhaust air from the kiln to warm incoming air and also captures radiant heat from the unit’s walls and roof, “reducing heat transmission to almost zero”. Heat from electric motor panels, frequency drives and piping is also recovered. “The latest system can save 25-30% of the thermal energy used to dry lumber by conventional technology,” said Mahild’s Lance Vinnell. “For a 200m³ capacity kiln, that’s a CO2 reduction of 650 tonnes a year, equal to the emissions from 130 homes.” He added that as part of its DryGreen initiative Mahild has also developed new energy management control systems. Among Mahild’s latest UK clients are Howie Forest Products and James Jones & Son, with the latter installing its kilns at its new Lockerbie plant.

  • August 2008

After careful selection and detailed technical studies from proposals of all renown potential suppliers Mahild was selected to supply and build the additional dry kiln capacity at Fort William mill.

The project includes 10 new all-aluminium dry kilns of a net volume of 200 m³ each and the installation of the most advanced kiln control system, MAHILD MM 4000.

The kilns will be equipped with the MAHILD ECO-VENT II – System to allow recovery of heat from the exhaust system of the dry kilns. The system provides low energy usage especially in winter months and helps to ruduce energy cost.

In addition to this it was also decided to install the MM4000 Energy Management System which allows operators to program product priorities and considers the energy available from heating plants on the site in order to manage best possible productivity and product quality.

Mahild is one of the most experienced kiln manufacturers in the world specialising in high production dry kilns for softwoods. It´s Technology is geared for large scale production of kilns and their components. Today’s manufacturing capacity allows production of 500 kilns per year in various sizes.
