MYHR Heat Pump Wood Drying Kiln

Kiln drying reduces the moisture content of wood. However, it does not remove the ability of wood to re-absorb any moisture that it comes in contact with.

That's why kilns are fitted with equipment to manipulate temperature, relative humidity and airflow rate throughout the timber stack during drying. This ensures that the wood is dried evenly and without defects.

1. High Efficiency
The MYHR Heat Pump Wood Drying Kiln is an energy efficient and environmentally friendly drying system. It uses hot air at controlled temperature and relative humidity to evaporate moisture from lumber, resulting in dried wood products that have superior quality.

The kiln has an energy system for heating and cooling, a ventilation system for releasing the moisture from the lumber, and an air humidi fi cation system to compensate for humidity losses due to air leakage. The energy consumed in the kiln depends on the type of kiln used, the size of the lumber load, and the drying schedule.

Various strategies have been developed to reduce the energy consumption of conventional kilns, including optimizing drying schedules, reducing air fl ow velocity, preheating the lumber with kiln exhaust air, and using direct-fi red heat systems or in-line heat exchangers in the kiln vents. However, these strategies do not necessarily result in significant energy savings.

2. Low Energy Consumption
Traditionally, wood drying involves the use of a conventional kiln to dry sawn timber. Conventional kilns are relatively simple to operate and maintain, but their energy consumption is high.

The main sources of energy required for a conventional kiln are for moisture evaporation, lumber heating, kiln ventilation, and air humidi fi cation. In addition, energy is consumed for kiln thermal losses and air leakage.

To improve the energy efficiency of conventional kilns, energy saving measures such as reducing air leakage and avoiding humidi fi cation are commonly implemented. However, bene fi ts in terms of energy savings are usually small.

In order to assess the feasibility of implementing different energy efficiency measures, an economic feasibility study has to be performed. This is important since the performance of an energy efficiency measure depends on both the operating conditions and climatic conditions (hot or cold weather).

3. Easy to Operate
Our wood drying kilns are easy to operate, saving you time and money. You can get wood to 20% moisture in 3-5 days and sell it on demand rather than storing it for months or a year.

This makes it easier for you to keep your inventory at a premium while making the most of your investment. It also reduces the risk of damage to your wood and helps you maintain high quality lumber while reducing operating costs.

Energy efficiency is a critical issue for industrial wood drying kilns. Traditional ventilation consumes 50-70% of total energy used in drying kilns (He et al. 2016).

4. Low Maintenance
Wood has a cellular structure which allows it to reabsorb water from its environment, whether that is a direct source of moisture, an adjacent material or humidity in the air. This natural capability is lost as the wood dries.

When drying, kilns use a combination of temperature and airflow to dry wood. These two factors work together to ensure a smooth and uniform drying process that prevents dry cracks in lumber.

The airflow moves the heat from the hot air source to the materials being dried. It also helps to keep the materials dry by keeping them from collapsing or case hardening.

The MYHR Heat Pump Wood Drying Kiln is a highly efficient and low maintenance kiln for kiln drying. It uses a touch screen intelligent control system which can easily set multiple drying time periods, operating modes (cooling / heating), temperature, humidity, etc., without any personnel care.
