The invention discloses a processing method of Gongcheng Yueyang Cake Heat Pump. The method is that fresh persimmon fruits with shaved skin are placed in the drying room, heated to 45 degrees C by heat pump for 30 hours, then put into the refrigeration dehumidification room, cooled to 20 degrees C by heat pump, and opened a low temperature dehumidifier for 18 hours continuously, and used a low temperature dehumidifier to remove circulating air. After repeating the above steps twice, the persimmon fruit with 40% moisture content was put into the oven again for low temperature and slow drying, and the temperature was set at 35 C for 20 hours. Persimmon cake was obtained by slowly pumping air through an axial flow fan controlled by a frequency converter, and water vapor in the oven was extracted without lowering the temperature in the oven. Using the heat generated by the high-efficiency and energy-saving heat pump to heat persimmon fruit in the drying room, the processing time is greatly shortened, the quality of persimmon cake is improved by low temperature dehumidification, and the processed persimmon cake is much better in color and taste than the persimmon cake directly dried by the existing technology.
【技术实现步骤摘要】
月杮杮饼热泵加工方法
本专利技术涉及月杮加工工艺,具体是一种月杮杮饼热泵加工方法。
技术介绍
柿饼是中国著名的传统小吃,营养价值很高,所含维生素和糖份比一般水果高1~2倍左右。传统的加工方法是将鲜果刨皮后通过自然晾晒、人工揉捏、熏硫防霉多道重复工序,历时二十余天方成柿饼。
技术实现思路
本专利技术的目的是要提供一种月杮杮饼热泵加工方法,采用该方法能大大缩短至只有5天的加工时间,加工出的柿饼在色泽、口感上要比传统加工方法制作的优质得多,同时完全符合高标准质量安全的要求。实现本专利技术目的的技术方案是:月杮杮饼热泵加工方法,包括如下步骤:(1)将刨好皮的柿子鲜果置于热泵烘房内,通过热泵烘干机对其进行升温,同时开启热风循环风机加热至45℃并保持恒温,热风加热时间30小时。(2)将加热后的柿饼从烘干房移出放入制冷除湿间,制冷除湿间内安装有制冷装置、低温除湿机、循环风机,通过制冷装置对柿饼进行制冷降温,强迫风循环,当温度降至20℃时维持恒温,此时开启低温除湿机,利用低温除湿机去除循环风中的水分,除湿工作时间18小时,停止除湿静置2小时后人工揉捏。(3)重复2次步骤(1)和步骤( ...
