Microwave technology in the drying process on the application of gelatin
Gelatin is a highly nutritious grain value . Lvpi be dominated by raw materials in different proportions with subjects such as sugar, wine, after cooking so many different machining processes , and finally dried slices molding polishing is finished.
Gelatin dry throughout the production process is an important part . It directly affects the production cycle , the resistance is to accelerate the production of gelatin . A method of drying chamber treatment with the past has been the traditional natural cool one thousand to carry out, but by the season and the ambient temperature limits long drying time . Occupy a large space. Because the relationship between supply and demand on the market abrupt change number of products far marrow meet people's needs. Therefore, on the basis of the existing supply and demand , in order to develop the production of gelatin , finding new ways to dry . Finally adopted the thermostat and microwave natural cool one thousand units of new technologies thread way to solve this practical problem.
    The composition of mainly animal skin gelatin as a raw material . After cooking cavity formed after the solid substance in the manufacturing process applications , the water content is about 30%. Whether through any method of drying , the water retention is generally not more than 15%. At the same time during the drying process . The temperature should not exceed 35 . C or more. So . From the above two conditions . Gelatin slow drying time , in order to shorten this particular issue . Using a combination of temperature and microwave drying latest methods .
    Microwave drying and conventional drying mechanisms differ in nature . It is through the media itself for the absorption of microwave energy is converted to heat , the temperature in the form shown. Temperature depends on the level dielectric absorption of microwave energy in nature. In the conventional dry conditions depends on convection conduction and radiation methods play a drying effect gradually from outside to inside . The microwave is not. It is both inside and outside heat. As the surface of the heat , the internal temperature is often higher than the external medium . Therefore, microwave drying results in the production of gelatin to obtain much shorter cycle , the output will increase more than 1 to 2 times .
    Microwave drying gelatin by the temperature and time constraints in the choice of the microwave heater , you should take into account the size of the space , the more so that the heating box size as possible, so you can ensure Phi and saddle cabinets mode power density . Therefore , the use of manufacturers of the existing conditions , taken as a room heater casing through trilateral size calculations , based on the offer to meet the design requirements. Recommended every wall in the house on the wall to impose 8D ~ 1o0 purpose copper network as cabinet material . In such a box-type heaters, equipped with a grant of wave energy power supply and reasonable feed antenna , etc., on the formation of a complete microwave systems.
