Microwave drying process of gelatin fumble
    1 . Microwave drying gelatin microwave equipment , there are two , the main difference lies in different microwave output power , one of the largest microwave output power of 5 kW . For these two different output power wave crest . The drying process should be different requirements. In either microwave equipment . During the drying process the temperature should not exceed 35 . C or more , or gelatin softening , deformation , bonding .
After many repeated trials. Since gelatin determined by the nature of things Chui . A cavity microwave drying process to low temperature for a long time method of operation. In order to develop a reasonable process procedures .
    Gelatin dry after 6 to 7 days after the thermostat , set the microwave drying chamber for drying , the process is to load film into a block of wood cabinets carton dog about 1000 to 1200 , regularly filled the room ( microwave cavity ) , a total of 25 to 30 boxes . Closed cabinet doors , microwave microwave energy emitted from the antenna is fed through the transmission waveguide , horn antenna to the box by means of space radiation , and then by the six-sided box wall cavity surface and reflected to the A box made of wall art , so the temperature increased. Each output microwave power for 30 minutes , down 20 to 25 minutes. And so on. Repeated 10 times . Anyway, both sides of the inverted box after shaping, parked eight to ten hours can be.
    3 . Microwave drying gelatin is filled with wooden box, although gelatin in the microwave field drying process, the absorption of microwave energy is converted to heat itself . After all, as wood products for the microwave energy absorption performance. Therefore, during the drying process is carried out simultaneously in two parts . But still play a leading role in wooden box wall .
From the above heating can be seen
   ( A ) in the same wooden box after microwave irradiation technique one or more walls of the box made ​​of gelatin temperature higher than the temperature approaching . And then gradually to the vertical and horizontal directions attenuation. If the first piece of gelatin counting the longitudinal temperature of 34 . C, . The temperature of gelatin to the third block is 33'C, and so on to the tenth block after the gelatin temperature only 30 degrees below it. Another head surgery boxes are basically the same .
( 2 ) the same on both sides of the tank wall temperature gradually decreasing to a central location .
( 3 ) housing at the center and the operation temperature is higher than the temperature of the bottom of the tank .
    ( 4 ) between the microwave drying phenomenon , in large majority of microwave energy consumed in a wooden box , the essence is the rotation of microwave energy conversion . In a sense, is not a reasonable scientific design with energy shake . The results tend to make dry dryness of the product there are significant differences . Therefore, the choice is pending drying process on the near -depth discussion .
