Drying Simulation Shows How to Save Energy and Costs

When it comes to industrial manufacturing, quality, safety and efficiency are often the key things.

Did you know that without compromising quality or safety, you might be able to save energy and costs a great deal or increase your yield with the same amount of energy if you are currently over-drying your product?

Take a moment to play with our new
interactive dryer to see one example of how using relative humidity based input volume control may help you increase your yield.

Optimized drying saves you energy and costs

You might be able to save energy and costs a great deal or increase your yield with the same amount of energy if you are currently over-drying your product. Take a minute or two to play with our dryer simulator below to see an example of how using relative humidity based input volume control may help you increase your yield.

1 - Input condensate measurement

Knowing the temperature and the mass flow of the condensate is essential when if you are aiming to increase the volume. Hint: In this example the optimal input volume level is ca 70 % without RH based volume control and to ca 87 % with RH based volume control switched on. You might also want to measure the dry matter percentage, density and special gravity of the condensate, depending on your product and your needs.

For this measurement point, Vaisala can offer you reliable temperature measurement.

2 - Input air measurement

The temperature of the warm air does not necessarily need to be changed at all even if your goal is to increase the yield. The relative humidity percentage & temperature, the mass of the air (e.g. kg/h), and the amount of water (e.g. g/kg) and are often key parameters in both input and exhaust air measurement.

For this measurement point, Vaisala can offer you the most accurate and stable relative humidity measurement combined with reliable temperature measurement.

3 - Exhaust air measurement

Vaisala HUMICAP HMT330 Series

Exhaust air measurement is probably the most important measurement point to focus on. As mentioned above, the parameters for input and exhaust air are usually the same meaning relative humidity percentage & temperature, the mass of the air (e.g. kg/h), and the amount of water (e.g. g/kg).

For this measurement point, just like above, Vaisala can offer you the most accurate and stable relative humidity measurement combined with reliable temperature measurement and they can in many applications be measured with the same product series as the condensate temperature measurement.

Vaisala HUMICAP® HMT330 series is an example of a product series that is popular in many drying applications and gives accurate and stable measurements of relative humidity and temperature.

Vaisala DRYCAP® DMT340 series is for very dry conditions. If you continue drying your product in a fluid bed dryer, for example, or you measure conditions ca under 5 %, you may want to consider the DMT340, which is optimized for the driest of conditions and focuses on measuring dew point
