Description

Technical Field

[0001] This invention relates to the field of honey processing technology, and more specifically, to a honey processing filtration device. Background Technology

[0002] As a natural nutritional product, honey, when processed, typically contains a large number of impurities, such as beeswax fragments, pollen grains, bee parts, and other insoluble suspended matter. To obtain commercially available honey with high clarity and stable quality, the raw honey must be melted, filtered, and refined.

[0003] Most existing honey filtration equipment uses a single mesh screen or filter cloth for static filtration. This method has significant drawbacks: First, honey viscosity varies greatly with temperature, and its fluidity is poor at room temperature, making gravity-based natural filtration extremely inefficient and unsuitable for continuous industrial production. Second, during static filtration, impurities easily accumulate rapidly on the filter screen surface, creating obstructions and clogging the filter pores. This increases filtration pressure and may even require frequent shutdowns for cleaning, severely impacting production continuity. To address the viscosity issue, some equipment has added heating mechanisms, but uneven heating often results in localized overheating that causes discoloration or damages active enzymes, affecting product quality.

[0004] Furthermore, while some known improved equipment incorporates stirring and heating functions, its feeding, filtration, and slag discharge processes are mostly separate steps, resulting in complex structures with numerous internal pipes that are difficult to clean and maintain. Especially during slag discharge, the entire container often needs to be opened, which is not only cumbersome but also prone to introducing new contaminants. Therefore, developing an integrated filtration device that achieves uniform heating, efficient filtration, and convenient slag discharge is a pressing technical challenge in this field. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a honey processing and filtration device that is compact in structure, easy to operate, and has high filtration efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A honey processing and filtration device includes an outer container shell and an inner container shell. The upper and lower ends of the outer and inner containers are fixedly installed via end caps. A feed inlet is also fixed to the upper end cap. The outer and inner containers form a liquid storage chamber for heating the interior of the device. Water, oil, or other media can circulate within the liquid storage chamber for heat preservation. An electric heating coil is also fixed within the liquid storage chamber to provide a heat source for heating the honey inside the device, thereby maintaining the honey's fluidity.

[0007] The container's inner shell is fixed with a partition, dividing the interior into upper and lower regions. A rotating shaft is rotatably mounted on the top end cap, and a drive motor for rotating the shaft is also installed on the top end cap. A stirring paddle is mounted on the shaft in the upper region. The upper region is used to store filtered honey. Under stirring and heating, crystallized particles are dissolved, increasing fluidity. The lower end of the rotating shaft passes through the partition and extends into the lower region, where two filter discs, I and II, are fixedly arranged in a stacked manner. A honey-guiding funnel is also fixed on the partition, and a conical plug is installed on the rotating shaft to seal the honey-guiding funnel, controlling the honey's falling speed. A honey-collecting inner cylinder is also provided in the lower region, and a discharge port communicating with the inside of the honey-collecting inner cylinder is fixed on the lower end cap.

[0008] Furthermore, a protective cylinder is fixed to the partition, the rotating shaft is sleeved inside the protective cylinder, and the stirring paddle crosses the top of the protective cylinder, thus isolating the rotating shaft from the honey and preventing the honey from leaking through the gaps at the rotating shaft.

[0009] Furthermore, a fixing rod is fixed to the lower end of the stirring paddle, and spiral blades distributed around the protective cylinder are welded and fixed on the fixing rod. Under the action of the spiral blades, the honey can be tumbled and transported upwards, increasing the uniformity of the honey's heating.

[0010] Furthermore, the container shell is a split type, including upper and lower half shells connected by flanges. Inlet and outlet ports are respectively provided on the two half shells, and a level gauge is installed on the upper half shell. The honey funnel has a double-layer structure with an internal cavity for honey flow. A through hole I is provided on the partition, and a through hole II is provided at the bottom of the honey funnel. The through hole I and the through hole II are connected through the cavity for honey discharge.

[0011] The conical plug seals the through hole II through the conical surface, and the conical plug is sleeved on the rotating shaft.

[0012] The rotating shaft is a hollow shaft, and a discharge drive assembly for driving the conical plug to move up and down is also installed on the rotating shaft. The unloading drive assembly includes a drive rod, the drive rod is mounted on the top of the rotating shaft via a bearing, a turntable is fixed to the top of the drive rod, and a locking nut is also installed on the drive rod; A lead screw nut is fitted onto the drive rod, and the tapered plug is mounted on the lead screw nut by a fastening bolt.

[0013] A limiting groove is provided on the side wall of the rotating shaft. The fastening bolt moves through the limiting groove, and the part of it stuck in the groove restricts the screw nut from rotating with the rotating shaft, so that it can only move axially.

[0014] The lead screw nut is provided with an annular groove, and the end of the fastening bolt is inserted into the annular groove.

[0015] The upper part of the drive rod is threaded for installing a locking nut, and the lower part is threaded for installing a lead screw nut. When the turntable is rotated, the lead screw nut drives the lead screw nut-fastening bolt-conical plug to move smoothly up and down along the rotating shaft, adjusting the honey flow rate.

[0016] Both filter discs I and II are bowl-shaped. This bowl-shaped structure generates centrifugal force when rotating, causing the honey to spread rapidly towards the edges, increasing the driving force for filtration. The pore size of filter disc I is larger than that of filter disc II to achieve staged filtration, i.e., first intercepting large particles of impurities, then intercepting fine suspended matter, thereby slowing down the clogging of the pores. A collection tray is fixed to the bottom of filter disc I, and a honey outlet is provided at the bottom edge of the collection tray to guide the pre-filtered honey into the central area of ​​filter disc II, prolonging the residence time of the honey on filter disc II.

[0017] Both filter disc I and filter disc II have downward-sloping skirts at their edges. Furthermore, a slag collection cylinder is provided in the lower region of the inner shell of the container. A slag storage cavity is formed between the slag collection cylinder and the honey collection inner cylinder. The slag storage cavity is provided with a slag discharge port. Under the action of centrifugal force, the skirt can guide the impurities thrown to the edge by centrifugal force downward, so that they fall into the slag storage cavity below in a waterfall shape for collection.

[0018] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the combination of a stirring paddle and spiral blades, creates a forced vertical circulation within the preheating zone, breaking the limitations of traditional jacket heating that relies solely on heat conduction and natural convection. This significantly improves the overall temperature uniformity of the honey, ensuring its low viscosity at the optimal filtration temperature and preventing localized overheating from damaging its beneficial components.

[0019] Meanwhile, the system employs stacked, bowl-shaped filter discs with decreasing pore sizes, combined with centrifugal force generated by rotation, achieving a dual-action filtration system of centrifugal and gravity. The bowl-shaped structure and downward-sloping skirt design allow honey to flow in a thin layer on the disc surface, extending the filtration time and facilitating honey passage. Simultaneously, impurities are trapped and slowly migrate towards the edges under centrifugal force, allowing for continuous discharge and ensuring both filtration speed and quality.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1

[0024] Please see Figures 1 to 3 A honey processing and filtration device is disclosed, the core components of which include an outer container shell 1 serving as an external protective and pressure-bearing shell, and an inner container shell 20 serving as an inner liner in direct contact with the material. The outer container shell 1 is a split type, comprising upper and lower half-shells 101, which are connected by flanges. Both are preferably made of food-grade stainless steel, such as SUS304 or SUS316L, to ensure hygiene and safety and resistance to acidic corrosion from honey.

[0025] The upper and lower ends of the container outer shell 1 and the container inner shell 20 are fixedly installed by end caps. Specifically, they are fastened by flanges and sealing gaskets. The upper end cap is also fixed with a feed port 3. The container outer shell 1 and the container inner shell 20 form a liquid storage chamber 102. The liquid storage chamber 102 is used to store the heat preservation medium, such as pure water or heat transfer oil. An electric heating coil 103 is also fixed in the liquid storage chamber 102. The electric heating coil 103 is a resistance heating element. After being energized, it can heat the heat preservation medium in the chamber. The volume and thickness of the liquid storage chamber 102 are calculated and determined according to the required heat load.

[0026] Meanwhile, inlet and outlet ports 5 are respectively opened in the upper and lower halves of the container shell 1 for injecting or discharging the insulation medium into the storage chamber 102. In order to observe the liquid level in the storage chamber 102, a level gauge 2 is installed on the upper half of the shell 101. To accurately control the heating temperature, a thermometer for monitoring the temperature is also installed on the upper half of the container shell 1 (not separately labeled in the figure), and its probe extends into the storage chamber 102. By combining the electric heating coil 103 with the insulation medium, the inner wall temperature of the container inner shell 20 can be ensured to be controlled within the optimal processing temperature range, usually 40℃-65℃, thereby effectively reducing the viscosity of the honey.

[0027] Please see Figure 3 Inside the inner shell 20 of the container, at approximately half its height, a partition 2001 is horizontally welded and fixed, dividing the interior of the inner shell 20 into upper and lower regions. The upper region is the mixing and preheating zone, and the lower region is the filtering and honey collection zone. A rotating shaft 13 is rotatably mounted on the surface of the top end cap, and a drive motor 8 for driving the rotating shaft 13 is also mounted on the top end cap. A stirring paddle 9 is mounted on the shaft of the rotating shaft 13 in the upper region. The outer edge of the paddle blade maintains a gap of approximately 20-50 mm with the inner wall of the inner shell 20, which effectively agitates the honey without causing scraping. To prevent honey from entering the gap between the rotating shaft 13 and the partition 2001 during agitation, a cylindrical protective tube 10 extends upward from the partition 2001. The protective tube 10 fits over the rotating shaft 13, and its upper opening is higher than the lowest point of the stirring paddle 9. The transverse connecting beam of the stirring paddle 9 crosses over the protective tube 10.

[0028] To further enhance the mixing effect, a fixing rod 901 is welded and fixed to the lower end of the stirring paddle 9, and spiral blades 902 distributed around the protective cylinder 10 are welded and fixed to the fixing rod 901. When the stirring paddle 9 rotates, the spiral blades 902 guide the honey in the center upward, thereby forming a convection circulation in the container where the center rises and the periphery falls, effectively preventing the honey from settling in the bottom corners and overheating.

[0029] Please see Figure 5 , Figure 7The lower end of the rotating shaft 13 extends through the partition 2001 into the lower area and is fixed with filter discs I 11 and II 12, which are stacked vertically. Both are fixed to the rotating shaft 13 by bushings and set screws and rotate synchronously with the rotating shaft 13. Filter discs I 11 and II 12 are both bowl-shaped, with their outer edges gradually curving upwards and extending outwards to form a filtering working surface. The pore size of filter disc I 11 is larger than that of filter disc II 12. Specifically, the pore size of filter disc I 11 is 80-120 mesh, used to intercept coarse impurities such as beeswax, while the pore size of filter disc II 12 is 180-220 mesh, used to intercept fine impurities such as pollen particles. A collecting disc 1101 is fixed to the bottom of filter disc I 11, and a honey outlet 1102 is provided at the bottom edge of the collecting disc 1101. Both filter discs I 11 and II 12 have downward-sloping skirts 1103 on their edges. As the filter disc rotates, the honey and impurities are subjected to centrifugal force. The honey can pass through the filter holes faster, while the impurities are intercepted. Because the filter disc is bowl-shaped, it can prevent the honey from being thrown out quickly along the surface, thus increasing the residence time of the honey on the surface of the filter disc. The impurities, under the action of centrifugal force, migrate along the surface of the filter disc towards the edge, and are finally thrown out quickly at the downward-sloping skirt 1103.

[0030] A honey-guiding funnel 18 is fixed on the partition plate 2001, and a conical plug 19 for sealing the honey-guiding funnel 18 is installed on the rotating shaft 13. A honey-collecting inner cylinder 15 is also provided in the lower area, and a discharge port 6 connecting the inside of the honey-collecting inner cylinder 15 is fixed on the lower end cover.

[0031] The honey funnel 18 has a double-layer structure with an internal cavity for honey flow. The internal cavity is annular, and a through hole I 17 is opened on the partition 2001. A through hole II 1801 is opened at the bottom of the honey funnel 18. Through holes I 17 and II 1801 are connected through the cavity for honey discharge. The cavity can hold a certain amount of honey for a short time, thus preventing it from entering the filter plate prematurely after the conical plug 19 is lowered and the drive motor 8 is started. The conical plug 19 seals the through hole II 1801 with its conical surface. The conical plug 19 is sleeved on the rotating shaft 13. When the conical plug 19 descends, the through hole II 1801 opens, allowing honey to pass through the partition 2001 and enter below.

[0032] Please see Figure 3 , Figure 4 , Figure 6 The rotating shaft 13 is a hollow shaft, and a discharge drive assembly 4 for driving the conical plug 19 to move up and down is also installed on the rotating shaft 13. The unloading drive assembly 4 includes a drive rod 401. The drive rod 401 is mounted on the top of the rotating shaft 13 via a bearing 403. A turntable is fixed to the top of the drive rod 401. A locking nut 402 is also installed on the drive rod 401. The drive rod 401 has corresponding threads. A lead screw nut 404 is fitted onto the drive rod 401, and a tapered plug 19 is mounted on the lead screw nut 404 via a fastening bolt 1901. Specifically, the lead screw nut 404 has an annular groove 4041, and the end of the fastening bolt 1901 is inserted into the annular groove 4041, thereby achieving axial fixation and relative rotation between the tapered plug 19 and the lead screw nut 404.

[0033] A limiting groove 1301 is provided on the side wall of the rotating shaft 13. The fastening bolt 1901 moves through the limiting groove 1301. In specific settings, the size of the fastening bolt 1901 and the limiting groove 1301 are similar, and the gap in the horizontal direction is less than 0.4um, so that the fastening bolt 1901 can only move up and down relative to each other along the limiting groove 1301. The conical plug 19 can be controlled to move after preheating or filtration.

[0034] Please see Figure 3 In the lower part of the inner shell 20 of the container, a slag collection cylinder 14 is also provided. A slag storage chamber 16 is formed between the slag collection cylinder 14 and the honey collection inner cylinder 15. The slag storage chamber 16 is provided with a slag discharge port 7. The bottom ends of the slag collection cylinder 14 and the honey collection inner cylinder 15 are pre-welded to the lower end cover. The lower end cover is fastened by a flange and a sealing gasket.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
