High Temperature dryer Controller, temp 35 – 300oC, many drying stages

For drying products in industrial fields and some drying products in civil, it will require a high temperature controller with many suitable features, typically multi-stage drying mode with different temperatures and times. In this topic we will learn about the high temperature dryer controller with a common drying temperature range of 35 – 300^oc (degrees Celsius).

In the industrial fields, a lot of materials, components, accessories, … need to be dried for surface, dried in the structure or heat treatment to harden or soften the material, so the industrial drying requirements are more complicated than use in civil. The drying temperature range of the industrial dryer usually has options of 35 – 160^oc, 35 – 200^oc and 35 – 300^oc, so Customers need to base on their usage requirements to choose a suitable and efficient dryer.

High temperature dryer controller in addition to the common features such as precise control of drying temperature, drying time, timer on and off, alarm, shutdown when overheating, drying mode… The feature of multi-stage drying with different temperatures and times is also widely used and important.

Usage in civil such as drying fruit, drying food, medicinal herbs, drying seafood, drying meat and drying cereals… are common products in daily life. Such products usually only need to use the Hot air dryers with a drying temperature range of 35 ~ 95^oc, which is very safe, only cereal grains, beans and nuts such as soybeans, Macca, cashews, lotus seeds,… need both stages: low temp drying and high temp drying ( drying to preserve and drying to eat) for instant cereal products or making cereal flour. Therefore, the high temperature controller used on industrial dryers is designed to allow setting of multiple drying stages.

The video above is a guide to using the multi-stage controller, how to use it first, just like other controllers, you need to press the Lock button to enter the settings, select different modes.

How many stages can you chooses, 1 to 6 stages is allowed, depends on how each product is dried. For example, cereal nuts as soybean, macca, cashew…needs to be dried at 60-70^oC for a long time about 3- 5 hours to reach necessary dryness, after that drying at 100 – 130^oC for a short time of 30-40 minutes to ripen, then the producer can set up 2 stages before start drying process. When using Controller of Mactech’s high temperature dryer, the user can set up to 6 stages to automatically change different temperature and time parameters. The stages will change automatically according to time of each stage.

This is also the most commonly used drying program on high-temperature dryers used in civil and industrial applications. In the field of drying industry, electronic components such as circuits board, paint products, plastics, mica, small transformer… all need many drying stages and multi-point thermal sensors.

Through the information above, The readers have a better understanding of high temperature dryer controller, please contact Mactech directly for more detailed advice, thank you for sharing information.
