Technical Field
[0001] This application relates to the field of lemon peel residue fermentation, and more specifically, to a biological fermentation process for lemon peel residue. Background Art
[0002] Lemon peel residue is a by-product in the lemon processing process, accounting for nearly half of the lemon fruit. However, in actual production, lemon peel residue is often regarded as waste for disposal, which not only causes a large amount of resource waste but also brings environmental pollution problems. Lemon peel residue is rich in dietary fiber. As the seventh major nutrient, dietary fiber has important physiological functions such as regulating intestinal function and preventing diseases in the human body and is an indispensable part of modern diet. Therefore, the effective utilization of lemon peel residue not only helps to solve the problems of resource waste and environmental pollution but also can develop foods or food ingredients with potential health value.
[0003] However, in the biological fermentation process of lemon peel residue, there is a key problem: lemon peel residue is often not evenly distributed after being sprinkled into the biological fermentation broth. This will lead to uneven microbial metabolism during the fermentation process, affecting the fermentation efficiency and product quality. Summary of the Invention

[0037] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.
[0038] An embodiment of the present invention provides a biological fermentation process for lemon peel residue, with reference to Figures 1-4, including a tank base 101, mounting bars 102, an annular support plate 103, and an arched frame plate 105. The annular support plate 103 is fixed to the top of the tank base 101. The annular support plate 103 is circular. Two mounting bars 102 are fixed to both sides of the arched frame plate 105. The mounting bars 102 are symmetrically arranged. Threaded mounting holes are provided in the mounting bars 102. Threaded holes are provided at the top of the annular support plate 103 corresponding to the mounting holes of the mounting bars 102. The arched frame plate 105 is mounted on the top of the annular support plate 103. The arched frame plate 105 is U-shaped. A spillage groove 106 with an outward opening is provided inside the arched frame plate 105. Two arc-shaped retaining bars 109 are fixed to the top of the annular support plate 103. The two arc-shaped retaining bars 109 are located on both sides of the arched frame plate 105.
[0039] Further, a number of rotation motors 108 distributed in an array are provided on both inner side walls of the spillage groove 106. The two columns of rotation motors 108 are symmetrically distributed. The rotation motors 108 on each side are inclined inward. An opening groove 111 is rotatably provided at the top of the rotation motor 108. A turntable 107 is mounted at the top of the opening groove 111. The rotation motor 108 is power-connected to a support shaft 112.
[0040] It should be further noted that when the rotation motor 108 is started, it can drive the support shaft 112 to rotate, and then drive the turntable 107 to rotate through the rotation of the support shaft 112.
[0041] Further, a number of opening grooves 111 with outward openings are provided on the four sides of the outer circumferential surface of the turntable 107. The opening grooves 111 are distributed in a circumferential array.
[0042] Further, a connection groove 121 is provided inside the turntable 107. An empty groove is provided in communication between the connection groove 121 and the opening groove 111. A feeding pipeline 120 is rotatably mounted at the top of the turntable 107. The opening of the feeding pipeline 120 is in communication with the connection groove 121.
[0043] Further, a number of input pipelines 104 with outward openings are provided in communication with both end faces on both sides of the arched frame plate 105. The input pipelines 104 are in communication with the feeding pipeline 120.
[0044] It should be noted that the input pipeline 104 is connected to the storage tank for shredded and refined lemon peel residues, and it is convenient for the lemon peel residues to be input into the feeding pipeline 120 through the input pipeline 104.
[0045] It is worth further noting that after the lemon peel residues are input into the feeding pipeline 120, they enter the connection groove 121, and as the turntable 107 rotates, the lemon peel residues falling into the connection groove 121 are thrown into the opening groove 111 through the empty groove and spilled outward.
[0046] Further, long retaining bars 117 are fixed to the lower parts of both inner walls of the spillage groove 106. The retaining bars 117 are inclined.
[0047] It should be further noted that when a part of the lemon peel residue is shaken off and does not fall beyond the baffle strips 117 on both sides, the lemon peel residue that has not fallen can be guided to slide down and stored through the inclined baffle strips 117, and the lemon peel residue that cannot carry out the subsequent fermentation work is centrally collected and processed, which is convenient for subsequent recycling and continued fermentation.
[0048] Furthermore, a fermentation chamber 116 with an upward opening is provided inside the tank body base 101. A rotating sleeve rod 115 is rotatably provided at the bottom of the fermentation chamber 116, and a plurality of stirring rods 114 arranged in a circular array are fixed to the outer end face of the rotating sleeve rod 115.
[0049] Furthermore, the bottom of the rotating sleeve rod 115 is connected to a stirring shaft 119. A stirring motor 118 is fixedly provided inside the lower wall of the fermentation chamber 116, and the bottom of the stirring shaft 119 is power-connected to the stirring motor 118.
[0050] It is worth further noting that when the stirring motor 118 is started, it can drive the stirring shaft 119 to rotate, and then drive the rotating sleeve rod 115 to rotate through the rotation of the stirring shaft 119, and then drive the stirring rods 114 on each side to rotate through the rotating sleeve rod 115.
[0051] It should be noted that the fermentation chamber 116 is used to place the fermentation liquid for fermentation work.
[0052] Furthermore, a power switch 110 is fixed to the side of the tank body base 101, and the power switch 110 is used to control the on-off of the overall power supply of the device.
[0053] The working steps of this invention are as follows:
[0054] S1. First, drive the entire tank body base 101 to move to the fermentation working position. The staff pour an appropriate amount of fermentation liquid into the fermentation chamber 116. Then, install the arched frame plate 105 on the top of the annular support plate 103, align the threaded mounting holes in the two side mounting strips 102 with the threaded holes in the annular support plate 103, and install and fix with threads to complete the installation work. Then, connect the output pipeline of the storage tank for the lemon peel residue used for fermentation to the input pipeline 104, which is convenient for the subsequent input of the lemon peel residue.
[0055] S2. Control the start of the stirring motor 118 through the power switch 110. The stirring motor 118 drives the stirring shaft 119 to rotate, and then drives the rotating sleeve rod 115 to rotate through transmission, driving the rotating sleeve rod 115 and a plurality of stirring rods 114 arranged in a circular array fixed to its outer end face to start rotating, which helps to uniformly mix the fermentation liquid in the fermentation chamber 116, and can also increase the oxygen content in the fermentation liquid to a certain extent, promote the activity of microorganisms, and thus improve the fermentation efficiency.
[0056] S3. Subsequently, the rotation motor 108 is started. By driving the support shaft 112 to rotate, the turntable 107 is driven to rotate through the rotation of the support shaft 112. Subsequently, the valve of the lemon peel residue storage tank is opened, so that the lemon peel residue enters the feeding pipeline 120 through the input pipeline 104. As the turntable 107 rotates, the lemon peel residue falls from the feeding pipeline 120 into the connecting groove 121, and is thrown into the opening groove 111 through the empty groove, and finally evenly sprinkles into the sprinkling groove 106, and falls downward into the fermentation liquid in the fermentation chamber 116 due to the gravity of the lemon peel residue itself. Due to the continuous rotation of the turntable 107, the lemon peel residue can be continuously sprinkled and fully contacted with the fermentation liquid, improving the uniformity and efficiency of fermentation, and thus realizing the uniform mixing of the lemon peel residue and the fermentation liquid.
[0057] S4. During the process of the lemon peel residue sprinkling, if some of the peel residues fail to successfully cross the retaining bar 117 and fall above it, these peel residues will slide down along the inclined retaining bar 117 to the preset collection area. At this time, the lemon peel residue in this collection area can be regularly cleaned and sent back to the chopping and refining device for reprocessing to ensure that all the peel residues can be fully utilized.
[0058] S5. When the fermentation reaches the predetermined time or effect, the valve connected to the lemon peel residue storage tank is closed, and the power input to the rotation motor 108 and the stirring motor 118 is stopped. At this time, the installation connection of the arched support plate 105 is removed, and the subsequent static fermentation work is realized. When the fermentation work meets the process requirements, the staff can conveniently pour out the fermentation liquid for the subsequent production process by holding the annular support plate 103.
[0059] S6. If continuous fermentation is required, only appropriate amounts of fermentation liquid and lemon peel residue need to be added again, and the above steps can be repeated.
[0060] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
