Description

Technical Field

[0001] This invention relates to the field of honey processing technology, specifically to a high-efficiency concentration device for honey processing. Background Technology

[0002] As a natural nutritional food, the concentration process in honey processing is crucial. The purpose is to remove excess water to meet national standards while preserving its unique active enzymes, aromatic substances, and color to the maximum extent. Traditional honey concentration techniques suffer from low heat transfer efficiency and high energy consumption: honey has a low heat transfer coefficient and slow evaporation rate under static or natural convection conditions. Efficiency drops sharply, especially as concentration and viscosity increase, leading to persistently high energy consumption. Uneven heating and concentration are also issues: honey near the heating wall is prone to overheating, while the central area remains cooler, resulting in uneven concentration. Localized overheating can trigger the Maillard reaction, causing a darker color. Therefore, there is an urgent need for a concentration device that achieves high efficiency, high quality, and low energy consumption. Summary of the Invention

[0003] In order to overcome the problems existing in the background art, the present invention provides a high-efficiency concentration device for honey processing, so as to solve the technical problem of the urgent need for a concentration device that achieves high efficiency, high quality and low energy consumption.

[0004] To achieve the above objectives, the invention is implemented through the following technical solution: A high-efficiency concentration device for honey processing includes a frame, a hopper, and a double-cone concentration chamber connected sequentially from top to bottom on the frame. The outer periphery of the maximum diameter of the double-cone concentration chamber is an arc-shaped surface, and the outer periphery of the maximum diameter is rolled and supported on multiple evenly arranged V-shaped rollers mounted on the frame. The double-cone concentration chamber is driven to rotate by a drive motor mounted on the frame. The upper inlet of the double-cone concentration chamber is rotatably connected to the lower outlet of the hopper through a sealed bearing, and the lower outlet is rotatably connected to a discharge pipe fixedly mounted on the frame through a sealed bearing. The outer wall of the double-cone concentration chamber is provided with a heating jacket with spiral heating wires laid inside.

[0005] Preferably, the spiral heating wire is electrically connected to a charging power supply fixedly installed on the outer wall of the double-cone-shaped concentration chamber, and the outer wall of the double-cone-shaped concentration chamber is also provided with a counterweight symmetrical to the charging power supply.

[0006] Preferably, an air inlet pipe is fixedly connected to the side wall of the discharge pipe. The air inlet pipe passes through the side wall of the discharge pipe and enters the interior of the discharge pipe to form an L-shaped structure with the outlet pointing upward and extending into the double-cone concentrating chamber. Dry hot air is introduced into the double-cone concentrating chamber from bottom to top through the air inlet pipe. The inner wall of the inlet pipe at the upper end of the double-cone concentrating chamber is connected to a connecting pipe that is rotatably connected to the lower outlet of the hopper. The connecting pipe is coaxially arranged inside the inlet pipe and connected to the inner wall of the inlet pipe through multiple connecting blocks. An air outlet gap is formed between the connecting pipe and the inlet pipe.

[0007] Preferably, one end of the connecting tube extending into the double-cone-shaped concentration chamber is connected to a dispersing disc one, and the bottom of the dispersing disc one is connected to a dispersing disc two through a plurality of ring-shaped connecting plates. A centrifugal jacket is formed between the dispersing disc one and the dispersing disc two. Under the action of rotation and centrifugation, the honey transported from the connecting tube passes through the centrifugal jacket and forms a thin film that is sprinkled on the inner wall of the double-cone-shaped concentration chamber. The connecting plates separate the honey to form gaps that facilitate the upward passage of hot air.

[0008] Preferably, the lower end of the discharge pipe is connected to a discharge hose, and the frame is also equipped with a discharge-promoting mechanism to assist the discharge hose in peristalsis and promote the discharge of concentrated honey; the discharge-promoting mechanism includes a second drive motor and two eccentric shafts. The two eccentric shafts are rotatably mounted on a support plate on the frame through bearings and are connected by gear transmission; the second drive motor is driven by one of the eccentric shafts, and the two eccentric shafts are located on both sides of the discharge hose, squeezing the discharge hose from both sides to assist in peristalsis.

[0009] Preferably, a rotating roller is rotatably sleeved on the eccentric shaft to reduce the friction between the eccentric shaft and the discharge hose.

[0010] Preferably, the drive motor is mounted on the frame, and a transmission plate is provided on the outer wall of the double-cone concentration chamber. An end face gear is provided on the transmission plate, and the output shaft of the drive motor is connected to the end face gear through gear transmission.

[0011] Preferably, the inner wall of the end of the connecting pipe that is rotatably connected to the hopper is connected to a spiral blade that extends into the hopper. When the connecting pipe rotates, it drives the spiral blade to rotate and transport the honey downwards.

[0012] Preferably, the air inlet pipe is equipped with a fan blade at the air outlet end of the double-cone condensation chamber. Hot air blows the fan blade to rotate, causing the hot air to spiral upward.

[0013] A method for concentrating honey using the aforementioned high-efficiency concentration device includes the following steps: S1, Add the honey that has been filtered to remove impurities to the hopper; S1, the drive motor drives the double conical concentration chamber to rotate at high speed, and the connecting tube and spiral blades rotate accordingly. The spiral blades push the honey downward into the connecting tube, and it continues to enter the centrifugal jacket between the first and second dispersing discs. Under the centrifugal action generated by the high-speed rotation of the double conical concentration chamber, the honey passes through the centrifugal jacket to form a thin film, which is then thrown onto the inner wall of the double conical concentration chamber to form a honey film that spreads along the inner wall. The heat generated by the spiral heating wire heats and evaporates the honey film. S3, the hot air entering the double cone-shaped concentration chamber through the air inlet pipe causes the fan blades to rotate, forming a spiral upward hot air, which carries the water vapor evaporated from the honey upward with the hot air and is discharged from the gap between the connecting pipe and the inlet pipe, carrying away the water vapor; S4. The concentrated honey flows downwards from the discharge pipe and discharge hose. As it flows through the discharge hose, the drive motor 2 rotates the eccentric shaft. The rotating rollers on the eccentric shafts on both sides exert a squeezing action on the discharge hose from top to bottom, and from outside to inside and then outward, causing the discharge hose to "perist" and promoting the discharge of concentrated honey.

[0014] The beneficial effects of this invention are: 1. High Concentration Efficiency and Excellent Quality Preservation: By driving the double-cone concentration chamber to rotate at high speed, centrifugal force is used to spread the honey into a uniform film on the inner wall of the chamber, greatly increasing the heating area and evaporation interface. At the same time, the spiraling upward dry hot air forms a counter-current flow with the honey film, efficiently carrying away the evaporated water vapor and creating conditions for rapid heat and mass transfer. This combination of "centrifugal film formation" and "cyclone drying" achieves rapid low-temperature concentration of honey, maximizing the preservation of heat-sensitive components such as active enzymes and aromatic substances in honey, and avoiding nutrient loss and flavor deterioration caused by prolonged high-temperature heating.

[0015] 2. Uniform film formation and thorough drying: Through the centrifugal jacket formed by the first and second dispersing discs located at the end of the feed, the honey is forcibly separated and evenly ejected under strong centrifugal force, forming a thin film of controllable and uniform thickness on the inner wall. The gaps formed by the connecting discs provide a smooth upward channel for hot air, allowing hot air to fully penetrate and glide over the surface of the honey film, improving drying efficiency and uniformity.

[0016] 3. Thorough discharge, suitable for high-viscosity materials: A specially designed discharge mechanism consisting of an eccentric shaft and rotating rollers is incorporated to address the rapid increase in honey viscosity during the later stages of concentration. This mechanism mimics the principle of a peristaltic pump, regularly squeezing the discharge hose to generate forward conveying force. This effectively overcomes the flow resistance of high-viscosity honey within the pipeline, ensuring that the concentrated honey is completely and smoothly discharged without any residue or blockage.

[0017] 4. Integrated Energy Utilization and Auxiliary Functions: Hot air drives the fan blades to rotate at the inlet, transforming it into a spiral upward airflow. This increases the contact time and disturbance with the honey film, improving the drying effect. The spiral blades at the feed end continuously push the honey downwards during rotation, ensuring continuous and stable feeding. The integrated design of the heating jacket and rotating cavity ensures direct and efficient heat transfer. Attached Figure Description

[0026] To make the objectives, technical solutions, and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0027] like Figure 1-8 As shown, the present invention provides a high-efficiency concentration device for honey processing, which mainly includes a frame 1, a feeding hopper 2, a double-cone concentration chamber 3, a drive system, a heating system, a hot air system, and a drainage mechanism.

[0028] The frame 1 serves as the supporting structure for the entire device. The feed hopper 2 is fixedly installed on the upper part of the frame 1 and is used for temporary storage and supply of honey to be concentrated. The double-cone concentration chamber 3 is supported and runs through the middle of the frame 1 through its upper and lower inlet pipes 31 and outlet pipes 32. Its shape is double-cone, with a cylindrical or arc-shaped section of maximum diameter in the middle. Around this maximum diameter, at least three circumferentially evenly distributed V-shaped rollers 11 are arranged, and the V-shaped rollers 11 are fixed to the frame 1 by bearing seats. The arc-shaped surface of the double-cone concentration chamber 3 rests on these V-shaped rollers 11, forming a stable rotational support system.

[0029] A drive motor 12 is fixed to the frame 1. A transmission plate 33 is welded to the outer wall of the double-cone thickening chamber 3, and an end-face gear 34 is mounted on the transmission plate 33. The output shaft of the drive motor 12 meshes with the end-face gear 34 through a small gear, thereby driving the double-cone thickening chamber 3 to rotate at high speed around its horizontal axis. The upper inlet pipe 31 of the double-cone thickening chamber 3 is rotatably connected to the lower outlet of the hopper 2 through a sealed bearing; its lower outlet pipe 32 is also rotatably connected to a discharge pipe 5 fixedly mounted on the frame 1 through a sealed bearing. Thus, the chamber 3 can rotate freely while the upper and lower interfaces remain sealed.

[0030] The outer wall of the double-conical concentration chamber 3 is covered with a sealed heating jacket 35. A spiral heating wire 36 is wound within this jacket 35 for heating the chamber. The spiral heating wire 36 is electrically connected via wires to a charging power supply 37 (such as a rotary connector or wireless inductive power supply module) fixedly mounted on the outer wall of the chamber. To balance the weight of the charging power supply 37, a counterweight 38 is installed on its opposite side.

[0031] An air inlet pipe 6 is fixedly connected to and passes through the side wall of the discharge pipe 5. After extending into the discharge pipe 5, the air inlet pipe 6 bends upward to form an L-shaped structure, with its outlet pointing upward and extending all the way into the double-cone-shaped concentration chamber 3. An external air source (such as filtered and heated air or inert gas) is introduced into the chamber 3 from bottom to top through the air inlet pipe 6. At the outlet end of the air inlet pipe 6 located inside the chamber, a fan blade 61 is installed. When the airflow is ejected, it drives the fan blade 61 to rotate, turning the incoming hot air into a spiral upward airflow.

[0032] A connecting pipe 7 is coaxially arranged inside the inlet pipe 31 at the upper end of the double-conical concentration chamber 3. The outer wall of the connecting pipe 7 is fixedly connected to the inner wall of the inlet pipe 31 by multiple radial connecting blocks 71, thereby forming an annular air outlet gap between the connecting pipe 7 and the inlet pipe 31. The upper end of the connecting pipe 7 is rotatably connected to the outlet of the feed hopper 2 through a sealed bearing. A conical or disc-shaped dispersing disc 72 is fixedly connected to the end of the connecting pipe 7 that extends into the chamber 3. At the bottom of the dispersing disc 72, a larger dispersing disc 74 is connected by multiple annularly distributed vertical connecting pieces 73. The dispersing disc 72, the dispersing disc 74, and the connecting pieces 73 together form an annular centrifugal jacket 75. A spiral blade 21 extending into the feed hopper 2 is also welded to the inner wall of the end of the connecting pipe 7 that is rotatably connected to the feed hopper 2.

[0033] At the lower end of the discharge pipe 5, a flexible discharge hose 8 is connected. On the frame 1, next to the discharge hose 8, a facilitating mechanism is installed. This facilitating mechanism includes a second drive motor 91 and two eccentric shafts 92. The two eccentric shafts 92 are horizontally and parallelly rotatably mounted on the support plate 13 of the frame 1 via bearings, and the two shafts rotate synchronously in opposite directions via a pair of meshing gears 94. The second drive motor 91 is connected to one of the eccentric shafts 92 via a chain or belt. The two eccentric shafts 92 are located on opposite sides of the discharge hose 8. A rotating roller 93 is rotatably mounted on each eccentric shaft 92. When the eccentric shaft 92 rotates, the two rotating rollers 93 periodically approach and squeeze the discharge hose 8 from both sides, generating a peristaltic wave transmitted from top to bottom. Multiple facilitating mechanisms can be provided to squeeze different positions on the discharge hose, creating a more effective peristaltic effect.

[0034] The method for concentrating honey using this device includes the following steps: S1: Preparation and Feeding. Add the raw honey, after preliminary filtration to remove visible impurities, into the feed hopper 2. Start the drive motor 12 to rotate the double-cone concentration chamber 3 at 800-2000 rpm. The connecting pipe 7 and the spiral blades 21 rotate accordingly, with the spiral blades 21 continuously and evenly pushing the honey from the feed hopper 2 downwards into the connecting pipe 7.

[0035] S2: Centrifugal Film Formation and Heating. Honey flows downwards along the connecting tube 7 into the centrifugal jacket 75, which consists of dispersing discs 72 and 74. Under the powerful centrifugal force generated by the high-speed rotation of the chamber, the honey is forced out from the gaps between the connecting discs 73 and spreads evenly as a thin film across the entire inner wall of the double-cone concentration chamber 3. Simultaneously, the spiral heating wire 36 is activated to heat the chamber wall. The heat is conducted to the honey film on the inner wall, causing the water in it to begin to evaporate. The heating temperature is controlled within a low-temperature range of 40-65℃.

[0036] S3: Swirl Drying and Exhaust. Start the hot air system, introducing dry air (or nitrogen) heated to 50-70°C by a heater (not shown) through inlet pipe 6. As the hot air flows past fan blades 61, it rotates, creating a spiraling upward airflow. This spiraling upward hot air flows over the honey film surface on the inner wall, quickly carrying away the evaporated water vapor. The humid, hot air continues to rise and is eventually discharged from the cavity through the outlet gap between connecting pipe 7 and inlet pipe 31, where it can be connected to a condenser to recover moisture. The flow rate and temperature of the hot air can be adjusted according to the initial concentration and evaporation stage of the honey.

[0037] S4: Concentration and Discharge. As water evaporates, the honey gradually concentrates and increases in viscosity on the inner wall of the cavity, slowly gathering towards the outlet pipe 32 at the bottom of the cavity under the influence of gravity and liquid flow. The concentrated honey flows through the outlet pipe 32 into the fixed discharge pipe 5, and then into the discharge hose 8. When the discharge concentration is detected to be close to the requirement or discharge is needed, the drive motor 91 is activated, driving the rotating rollers 93 on the two eccentric shafts 92 to rotate. The rotating rollers 93 periodically squeeze the discharge hose 8 with a specific phase difference, generating a pushing action similar to intestinal peristalsis, effectively discharging the high-viscosity concentrated honey from the hose and collecting it into the finished product container; the diameter of the discharge pipe 5 is set to be larger than that of the connecting pipe to promote the rapid discharge of honey.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
