Energy-conservation changing food waste processing method 〉
Energy-conservation changing food waste processing method, it comprises the steps: to make feed(raw material)inlet 203 to be higher than export of goods in process of manufacture 606, and semi-finished product inlet 705 is higher than product outlet 716.When aerobic reative cell 20 and negative pressure drying sterilizing chamber 70 are installed, make it have the slope of 0.015--0.03 respectively.Slope is the difference in height at two ends of aerobic reaction chamber 20 and negative pressure drying sterilizing chamber 70 and the ratio of its length.Having certain slope moves forward material under the effect of self gravitation.
Raw material is sent into feed(raw material)inlet 203; Raw material is carried out biochemical reaction in aerobic reaction chamber 20; Semi-finished product behind the biochemical reaction are discharged by export of goods in process of manufacture 606, be sent to semi-finished product inlet 705; Vacuum is taken out negative device 9 extracting gases, makes negative pressure drying sterilizing chamber 70 remain on negative pressure state; Semi-finished product are carried out drying in negative pressure drying sterilizing chamber 70 handle; High temperature hot gas in the air-heating furnace 1 is sent into hot gas air deflector 8 by high temperature hot gas inlet 726; Semi-finished product in high temperature hot gas in the hot gas air deflector 8 and the negative pressure drying sterilizing chamber 70 carry out heat exchange, semi-finished product are carried out drying handle; After becoming low temperature hot gas after the high temperature hot gas heat exchange, enter into low temperature hot gas inlet 613 from heat outlet 723; Low temperature hot gas enters into aerobic reaction chamber 20, promotes that raw material carries out biochemical reaction; Behind the low temperature hot gas process aerobic reaction chamber 20, discharge from exhaust port 215.
The step of carrying out biochemical reaction in the raw material aerobic reaction chamber is further comprised:
Raw material is carried out the low-temperature aerobic reaction in low-temperature aerobic reative cell 3;
Warm aerobic reaction during material after the low-temperature aerobic reaction treatment carried out in middle temperature aerobic reaction chamber 4;
Material after the middle temperature aerobic reaction processing is carried out the high-temperature aerobic reaction in high-temperature aerobic reative cell 5.
Aerobic reactor needs certain filtrated air to offer biological bacteria as aerobic reaction; Vacuum drying needs 〉=140 ℃ temperature to provide the drying thermal source for vacuum drying in order to meet national relevant regulations.Therefore, adopt air-heating furnace to provide thermal source for this drier, dried waste heat (air-flow) is sent into the aerobic reaction chamber by heat resisting exhauster again, and on the one hand as indispensable oxygen, two aspects replenish as the heat energy of biochemical reaction (＜80 ℃) again.
Embodiments of the present invention have a following beneficial effect:
1, energy savings, about 100 ℃ of the boiling point of natural water under normal pressure, for example, boiling point is about 68 ℃ under negative 0.5 atmospheric pressure, reaches boiling point equally, can save heat energy more than 40%.When wall scroll production line disposal ability 200t/d, only dry sterilization can be saved 11664 * 106 kilocalories of the energy (amount to about 1080 tons of diesel oil, do not comprise the UTILIZATION OF VESIDUAL HEAT IN of aerobic biochemical reaction) every year.
2, " two step handle " because two groups of equipment independent operatings, not only the antivacuum relatively processing of disposal ability increases, and the easier control of processing parameter.
3, product reaches under the situation of same moisture content, because the vacuum drying and the needed temperature of sterilizing can reduce the loss of product nutrient substances far below the temperature under the normal temperature state as far as possible.
4, to low even variation, the mushroom that makes all participate in biochemical reaction could find a biological respinse section that meets most itself automatically by height for flow of process air and material to be processed antikinesis, temperature.Too requirement of temperature characterisitic to bacterial classification can utilize bacterial classification to greatest extent, and reduces the processing cost of bacterial classification.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
