专利汇可以提供Apparatus for processing food wastes专利检索，专利查询，专利分析的服务。并且An apparatus for continuous processing of raw refuse composed primarily of food wastes and incorporating other wastes such as limited quantities of paper and plastic material wherein the raw refuse material is comminuted and conveyed to a pair of heated platen members and is continuously deposited between the platen members. The heated platens are caused to revolve continuously in such manner as to define a space between the platen members during a portion of each revolution to allow raw refuse material to be conveyed between the platens for depositing, and to cause the heated platens to move into juxtaposition during other portions of each revolution, thereby compressing the comminuted refuse placed therebetween. The platens are caused to revolve at a particular speed that insures compression and complete drying of the refuse during one revolution of the platens. After being compressed and dried by the heated revolving platens the cured refuse is scraped from the platens and is conveyed to a receiving vessel such as a hopper, where the cured refuse may be placed into containers in flake or wafer form or where the cured refuse may be comminuted and then placed into containers.，下面是Apparatus for processing food wastes专利的具体信息内容。
