[0056] Embodiment 2

[0057] Reference Figures 1-10 The second embodiment of the application is based on the previous embodiment, and the difference is that the caked distiller's grains are preliminarily crushed to improve the contact area and the dehumidification effect, and prevent caking and blockage.

[0058] Specifically, the air outlet 1002 is internally provided with a flow channel 1007, the flow channel 1007 is internally rotatably provided with a rotating wheel 1008, the flow channel 1007 is also rotatably provided with a rotating shaft 1009 penetrating therein, the rotating shaft 1009 is rotatably provided with a fan shaft 1011 between the rotating wheel 1008, and the fan shaft 1011 is externally covered with a fan blade 1012.

[0059] Further, the rotating wheel 1008 is also rotatably provided with an adjusting ring 1019 at an end face thereof, the adjusting ring 1019 is provided with a convex column 1013 at an end face thereof, the fan shaft 1011 is also provided with a hollow ring 1014 at an end face thereof, and the convex column 1013 is slidably arranged in the hollow ring 1014.

[0060] Wherein, the flow channel 1007 is Z-shaped, the hollow ring 1014 is waist-shaped, and a sliding groove is internally and hollowly formed in the hollow ring 1014, the convex column 1013 is fixedly connected with the fan shaft 1011, and the fan blade 1012 is circumferentially arranged with eight, when the convex column 1013 slides in the hollow ring 1014, the hollow ring 1014 drives the fan shaft 1011 to rotate, so as to adjust the angle of the fan blade 1012.

[0061] Exemplarily, in the embodiment, the adjusting ring 1019 is manually rotated, after the adjustment is completed, the adjusting ring 1019 is fixedly attached to the rotating wheel 1008 and synchronously rotates with the rotating wheel 1008, in other embodiments, a micro motor is arranged between the adjusting ring 1019 and the rotating wheel 1008, for driving the adjusting ring 1019 to rotate relative to the rotating wheel 1008.

[0062] More preferably, the rotating shaft 1009 penetrates into the feeding port 200 and synchronously rotates with the crushing head 2003, the crushing head 2003 is provided with at least one grid 2004, the grid 2004 can synchronously slide and penetrate the crushing grid 2002, and simultaneously crushes the solid waste lees on the base plate 2001.

[0063] Wherein, the grid 2004 is circumferentially arranged on the crushing head 2003, the base plate 2001 and the grid 2004 are both semicircular, the hollows on the crushing grid 2002 and the grid 2004 are both parallelly arranged stripe grooves, and the stripe grooves of the two are crossly arranged, so as to realize the free rotation of the crushing head 2003 between the two base plates 2001.

[0064] More preferably, the two end faces of the grid 2004 in the embodiment are respectively a sharp cutting blade and a blunt crushing blade, which are respectively applied to different scenes of crushing precision, and are switched by different rotating directions.

[0065] In summary, in use, as the gas is continuously circulated, the fan blades 1012 and the runner 1008 are driven to rotate when the flow channel 1007 flows out, so that the rotating shaft 1009 continuously rotates the crushing head 2003 to pre-crush the clumped solid distiller's grains in the distiller's grains, increase the contact area with the gas, thereby improving the dehumidification effect, while preventing the clumped distiller's grains from blocking the feed inlet 200. The preliminary crushing is carried out through the gas flow, which reduces energy consumption. Meanwhile, the fan blades 1012 are distributed in a circular array, which prevents some distiller's grains shells from passing through and being blown out with the gas flow, thereby affecting the gas circulation, and achieving two goals at once.

[0066] More preferably, when the adjusting ring 1019 rotates, the hollow column 1014 is driven to rotate through the convex column 1013, and finally the fan blade shaft 1011 is driven to rotate, thereby finally adjusting the angle of the fan blades 1012. Different angles of the fan blades 1012 can adapt to different scenarios: when the fan blades 1012 are parallel, the blocking effect on the distiller's grains shells is optimal; when the fan blades 1012 are respectively oriented at two different angles, the rotating direction of the runner 1008 is changed. When the crushing blades of the crushing head 2003 are blocked and stuck, the rotating direction of the grid 2004 is adjusted by switching the rotating direction, and the stuck distiller's grains are cut into pieces by the relatively sharp cutting blades rotating in the opposite direction.

[0067] Embodiment 3

[0068] With reference to Figures 1-10 For the third embodiment of the present application, which is based on the previous embodiment, the difference is that the two substrates 2001 are floating type and can slide up and down in a staggered manner or as a whole, thereby achieving self-adaptive crushing effect adjustment and unblocking the distiller's grains that block the feed inlet 200.

[0069] Specifically, the outer wall of the feed inlet 200 is provided with a chute 2024, one end of the substrate 2001 is provided with a support plate 2005, one end of the support plate 2005 extending to the outside of the feed inlet 200 is provided with a sealing plate 2006, and the sealing plate 2006 is externally attached to the chute 2024.

[0070] More preferably, the sealing plate 2006 has two parallel sealing plates 2006, and one end of the sealing plate 2006 is further provided with a rack 2007. The two racks 2007 are further provided with a gear 2008, and the gear 2008 is slidingly provided with a floating column 2009.

[0071] The two racks 2007 are parallel and simultaneously meshed and limited by the gear 2008. Without external force, the gear 2008 and the rack 2007 slide up and down synchronously, and cannot slide in the axial direction of the gear 2008. The sealing plate 2006 is always attached to the chute 2024 during the up and down process, thereby preventing the distiller's grains from leaking out.

[0072] Preferably, the first notch 2011 and the second notch 2012 are arranged on the outer wall of the feeding port 200, the floating column 2009 is provided with a positioning block 2013, the positioning block 2013 is slidingly arranged in the first notch 2011, and the floating column 2009 is further provided with a rolling ball 2014 which is rollingly arranged in the second notch 2012.

[0073] The first notch 2011 and the second notch 2012 are arranged in a triangular shape, and the second notch 2012 is connected to the first notch 2011 through a circular surface, so that the rolling ball 2014 can be lifted and rolled to the first notch 2011 after rolling to the end of the second notch 2012.

[0074] Preferably, a spiral groove 2015 is arranged on the inner wall of the gear 2008, the floating column 2009 is further provided with a sliding column 2016 which slides in the spiral groove 2015, and the gear 2008 and the positioning block 2013 are further provided with an elastic element 2017.

[0075] The elastic element is a spring, and the elastic element is used to push the floating column 2009 and the rolling ball 2014 to always slide along the surface of the notch, so that the rolling ball 2014 also rolls along the surface of the notch as the two substrates 2001 float up and down.

[0076] Meanwhile, the positioning block 2013 and the first notch 2011 are also provided with elastic elements on both sides, so that in the initial balanced state, the positioning block 2013 and the rack 2007 and the substrate 2001 connected thereto are located at the uppermost end of the crushing head 2003, and at this time, only the last end of the grid is used for crushing, and as the amount of discharged distiller's grains increases, the elastic force is reduced, and at this time, a larger area of the grid is needed for stirring and crushing.

[0077] In summary, in use, as the amount of discharged distiller's grains increases, the gravity drives the substrate 2001 to descend, the two racks 2007 and the gear 2008 are synchronously fixed to slide downward, the grid 2004 passes through a larger range of the substrate 2001, the stirring and crushing effect is stronger, and the crushing and separating effect is better.

[0078] When blocked, the amount of distiller's grains falling from the substrate 2001 is reduced, resulting in a large amount of accumulation on the substrate 2001, and finally the positioning block 2013 is greatly lowered by overcoming the elastic force, until the rolling ball 2014 starts to climb along the circular surface to the first notch 2011, due to the displacement of the floating column 2009, the sliding column 2016 is pushed to slide in the spiral groove 2015, and finally the gear 2008 rotates relatively, so that the two racks 2007 move in opposite directions, the two substrates 2001 are staggered and separated, a gap is formed, and the accumulated distiller's grains directly fall, avoiding the blocking situation.

[0079] Embodiment 4

[0080] Referring to Figures 1-10 For the fourth embodiment of the present application, the energy-saving feed processing method is applied to the above-mentioned waste distiller's grains recycling device, realizes 100% resource utilization of waste, and has more comprehensive nutrient retention and higher feed quality than conventional distiller's grains feed.

[0081] Specifically, an energy-saving feed processing method comprises the following steps:

[0082] S1: The wet distiller's grains are sent into the feed inlet 200 through the conveying belt, the pre-crushing mechanism 201 is triggered to work, the crushing head 2003 rotates at a low speed, and the caked distiller's grains with a particle size of >50mm are squeezed through the crushing grid 2002 and directly fall into the conversion and recovery cavity 100.

[0083] In this embodiment, the crushing head 2003 rotates at a low speed of 15-20 rpm, the caked distiller's grains with a particle size of >50mm are crushed, which facilitates the recovery of subsequent high-protein components, and the grid gap is dynamically adjusted according to the viscosity of the distiller's grains.

[0084] At the same time, the distance between the crushing head and the grid should be >20mm, so as to realize only crushing the caked structure and avoid excessive pressure causing juice to seep out and resulting in nutrient loss.

[0085] S2: The loose distiller's grains enter the cloth distribution pipe 1005, the transmission roller 1006 drives the distiller's grains to uniformly fall and form a thin layer covering the surface of the dehumidifying cylinder 101 through the axial array of holes and grooves.

[0086] As the dehumidifying cylinder 101 rotates, the distiller's grains roll on the cylinder surface and contact with hot air to be taken away moisture, while the wet and hot waste gas is discharged from the gas outlet 1002 and the moisture is recovered through the condenser for reuse.

[0087] In this embodiment, the dehumidifying and dewatering is divided into two stages. In the first stage of 0-10 min, the surface water is rapidly evaporated by 80℃ hot air to reduce the moisture content to 45%; in the second stage of 10-25 min, the internal water is evaporated by 75℃ hot air to reduce the moisture content to 10%.

[0088] S3: The dewatered distiller's grains are controlled to roll in the inclined cavity, the distiller's grains are gathered to the low-position discharge port along the slope, and the distiller's grains shells are carried by the airflow to the high position to realize separation and collection.

[0089] In this embodiment, a 30cm high baffle step is arranged in the transfer bin 1003 to prevent the distiller's grains shells from flowing back, and the vibration during the rotation of the dehumidifying cylinder 101 promotes the distiller's grains shells to slide into the collection groove.

[0090] S4: The bran discharged from the transfer bin 1003 is transported to the biomass combustion furnace to heat the circulating gas by combustion, reducing energy consumption; at the same time, the rice kernels in the discharge port are added with a bentonite binder after removing dust by a double-layer vibrating screen, and then enter a ring die pelletizer to produce feed pellets.

[0091] In summary, the present processing technology adopts a dynamic drying method to realize 100% resource utilization of waste, and each production line can process 6 tons of wet distiller's grains per hour. The fresh distiller's grains with a water content of about 65% can be dried to below 10%, and then the bran and kernels in the distiller's grains are separated. The bran is used as biomass fuel to provide heat for drying fresh distiller's grains, and the kernels are made into feed pellets for sale. The conversion of brewing waste into high-value-added products is realized, and the entire feed production process adopts non-extrusion crushing and thin-layer dehydration to retain heat-sensitive nutrients such as β-glucan and acid-soluble protein in distiller's grains, so the nutrient quality is more comprehensive. The entire process highlights the energy-saving advantage of "biomass energy closed loop" and meets the policy guidance of green manufacturing.
