Definitions
- step f) further comprises the step of determining a temperature distribution in the product based on the image data, and wherein in step g), the applied microwave power to the product is further controlled based on a maximum, average, or minimum value of the temperature distribution in the product.
- the method comprises the step of providing cooling water.
- the cooling water is used in a dummy load or isolator to absorb mismatched (i.e. reflected) microwaves, thereby preventing them from bouncing back to the magnetron.
- the cooling water is used for cooling the magnetron.
- Using cooling water both in the isolator and for cooling the magnetron significantly improves the operation of the microwave applicator and the life expectancy of the electronics inside.
- the microwave (MW) unit is preferably not operated without a supply of cooling water at the correct temperature of, for example, between 10°C and 30°C. This can be enforced by requiring, for example, that the magnetron will not start if the water flow is too low or if the cooling water is too hot.
- the imaging device comprises an infrared camera.
- the camera allows capturing image data indicative of a temperature distribution in a product which is treated in the microwave applicator.
- the camera then provides real-time input data which can be used by the controller to adapt the power at which the microwaves are applied to the product based on the captured image data.
- the cavity has a door which is equipped with one or more of, preferably all of, the following types of sealing: Copper alloy spring contactor for the protection for MW radiation; Teflon seal for the protection against irradiated heat; and/or Rubber seal for the air-tightness of the cavity.
- the imaging device is a spectral imaging device.
- the system further comprises one or more positioning blocks for supporting the product.
- the camera allows capturing image data indicative of a temperature distribution in in a product which is treated in the microwave applicator.
- the controller (300) of the microwave system (100) then adapts the power at which the microwaves are applied to the product based on the captured image data.
- the microwave system (100) is equipped with an emergency stop button in the door panel of an associated electrical cabinet. After pressing it, the whole microwave system (100) shuts down, including the vacuum pump (280), and the integrated water pump and chiller (285). The alarm indicator light will be on until the emergency stop button is released and the system is reset by pushing a reset button. The emergency stop button is released by pulling the knob of the button back.
- the upper valve (291) When the upper valve (291) is opened, the bottom of the drying vessel opens and the product falls to the collector chute. Furthermore, the product is transferred to the collection tank by opening the lower valve (292). After the discharge, the collection tank is kept under vacuum by closing the lower valve (292).
- the applied microwave power to the product is further controlled by 1) determining a temperature distribution in the product based on the image data, and 2) a maximum, average, or minimum value of the temperature distribution in the product.
