16、, na device intended for the removal ofliquid by evaporation from processed or unprocessed foodscraps and limited amounts of cardboard, paper, and biode-gradable food service wear.3.1.1.1 DiscussionWaste material is loaded into a me-chanically agitated tank which is heated, via immersion heatersin a
17、n oil bath, to evaporate any liquid contained in the wasteproduct. The evaporated liquid is conveyed by a closed-loopblower system through a condenser. The condensate is thendrained to a sanitary sewer system and the dry air is reheatedand pumped back into the dehydrator tank to accept moreevaporate
18、d liquid. Dehydrators are not intended for processingglass, china, metal, wood, clam, or oyster shells. Dehydratorsmay consist of the following principal parts: tank, motor,agitator paddles, condenser, heaters, blower, condensate pump,discharge door, input door, and casters.4. Classification4.1 Gene
