Claims

[Claims for Utility Model Registration] A central processing unit (CPU), a read-only memory (ROM) in which multiple basic drying programs are stored, and a random access memory (RAM).
), an input means, and an output means, and in the case of control operation, after calling a desired one basic program from the ROM and loading it into the RAM as an operation program, the CPU Based on the dry bulb temperature and wet bulb temperature in the leaf tobacco drying chamber that are stored in the RAM, a temperature command value and a humidity command value are obtained by referring to the operation program and performing necessary calculations, and the temperature command value is outputted to the output means. Similarly, the humidity command value is sent as a control command to the heating means of the drying chamber through the output means, and the humidity command value is sent as a control command to the air intake means as the humidity adjustment means of the drying chamber, so as to control the temperature and humidity in the drying chamber. In the automatic leaf tobacco drying control device, the RAM has a basic area for loading the desired one basic program called from the ROM, and also has a basic area that is not related to the basic program stored in the ROM. The CPU has an application area for loading an arbitrary drying program (hereinafter referred to as an application program) without an application program, and when the operator selects drying control using the application program, the CPU detects this and The drying chamber is flexible in application, characterized in that the operator is allowed to set an application program in the application area through an input means, and after the setting is completed, the temperature and humidity in the drying chamber are controlled according to the application program. Automatic leaf tobacco drying control device.
