We are doing this by operating within a temperature range of 150-160 degrees Fahrenheit, having adequate ventilation, and carbon filters. Furthermore, with the multiple layer of insulation surrounding our whole heating system, we are able to better retain the heat within the system as well as protecting other components such as our electrical system. Lastly, we have a middle bearing support located within the metal chamber to ensure stable rotation of our agitator when moving the food waste.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">AGITATOR <\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Within the heating chamber, the agitator is attached within the middle to help rotate the food and ensure  even heat distribution of the food waste. The agitator makes sure that one piece of food waste does not overheat compared to the rest of the food waste. Furthermore, with proper ventilation, heat control, and the use of an agitator, we mitigate hazardous gas production such as methane which occurs when food is overheated<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"https:\/\/scholars.spu.edu\/lance\/wp-content\/uploads\/sites\/58\/2022\/04\/IMG_0580-3.mov\"><\/video><figcaption>Agitator operating with dehydrated food.<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/scholars.spu.edu\/lance\/wp-content\/uploads\/sites\/58\/2022\/04\/image.jpg\" alt=\"\" class=\"wp-image-186\" width=\"402\" height=\"512\" srcset=\"https:\/\/scholars.spu.edu\/lance\/wp-content\/uploads\/sites\/58\/2022\/04\/image.jpg 350w, https:\/\/scholars.spu.edu\/lance\/wp-content\/uploads\/sites\/58\/2022\/04\/image-235x300.jpg 235w\" sizes=\"auto, (max-width: 402px) 100vw, 402px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Agitator build with a motor at the top attached to our rod with set screws, a bearing to ensure proper rotation, and a metal sheet that has been shaped and heated to form blades.
