GANN HYDROMAT TK-MP 501 This latest model of the Hydromat TK-MP series offers a wide range of facilities for optimising timber drying, as has been unknown so far in this variety from other controllers. It sets new standards in fully automatic control of the drying process. The display and operating devices are combined in a modern LCD touch screen, which allows inputs by just touching the relevant part of the screen. Drying schedules for 250 species of wood and for a wood thickness from 20 mm to 140 mm are stored in the controller’s memory. They can be modified by the operator within preset safety limits, if this should be required according to the particular efficiency of the dryer. The built-in program editor permits to modify standard drying schedules by inserting or deleting drying steps. With timbers that are difficult to dry and tend to warping and splitting, periodical interim conditioning phases can be inserted. These serve to relieve stress that has built up and to improve the drying quality. Modified standard drying schedules can be stored in a register for easy reuse. The microprocessor-operated signal amplifier digitally transfers the measured values to the controller. To ensure an optimum accuracy of the readings, the individual resistance curves of 250 species of wood are stored in the signal amplifier module. Furthermore, proper function of the measuring points is permanently verified by the controller. Up to 16 wood-moisture measuring points can be connected to the controller. Eight measuring points can be used for core and for shell measurement. This permits automatic adaptation of drying control at too great a difference between core and shell moisture. This may cause too fast drying of the shell layer and may lead to case hardening. On request the controller can be equipped with radio based measuring points for wireless transmission of the readings. Apart from control of the drying cycle as governed by the continuously measured wood moisture content, the user can also enter time-based drying programs of his own. Instead of real wood-moisture measuring points, a fictitious measuring point can be used for control of the drying process, too. A supplementary equipment permits variable control of the fan speed, also taking into consideration, besides species and thickness of the timber, the thickness of the stickers used. Hardware Modular design with add-on I/O-modules for future applications. Modules are connected with the control unit via digital CAN-bus. Freely programmable switch functions as entered by the user. Up to 16 wood moisture measuring points, optionally in wireless design. Graphical user interface for easy programming. Connection port for colour inkjet printer to protocol the drying cycle. Device with up to 16 additional temperature measuring points for control and documentation of heat treatment of timber designed for packing purposes (optional equipment). Software Standard drying schedules for 250 species of wood and for a wood thickness from 20 mm to 140 mm, considering thickness of the stickers and air speed. Standard drying schedules can be modified and stored for easy reuse. Program editor renders additional intermediate program steps possible. GANN Control Systems for Timber Drying Kilns
