An energy-saving gelatin production device

Abstract

This invention provides an energy-saving gelatin-cooking device for donkey-hide gelatin production, relating to the technical field of donkey-hide gelatin production. It includes a support platform, with a main gelatin-cooking furnace fixedly connected to the top of the support platform, and a preheating tank fixedly connected to the top of the support platform. This invention recovers residual heat generated during gelatin-cooking by incorporating heat-conducting and gas-conducting components. The waste heat recovery tank absorbs the external temperature of the main gelatin-cooking furnace through a heat-conducting medium inside a spiral heat-conducting channel, and transfers it to the interior of the preheating tank via a heat-conducting circulation pipe and heat exchange coil, thereby preheating the water used for gelatin-cooking. Furthermore, the steam generated during gelatin-cooking can be preheated by hot gas delivery pipes and hot gas delivery coils, thereby reducing the workload of the main heating device, shortening the cooking cycle, and achieving dual recovery of waste heat, significantly reducing production energy consumption.

Description

Technical Field

[0001] This invention relates to the technical field of donkey-hide gelatin production, and in particular to an energy-saving gelatin-boiling device for donkey-hide gelatin production. Background Technology

[0002] As a traditional tonic, donkey-hide gelatin's core production process is boiling and concentrating the gelatin. This process has stringent requirements for temperature stability, heat uniformity, and energy consumption control. Currently, traditional donkey-hide gelatin boiling equipment on the market still has many technical defects in actual production applications, making it difficult to adapt to the demands of modern, energy-saving, and efficient production. When existing traditional glue-cooking equipment is working, the main furnace continuously supplies heat through the main heating device to maintain the glue-cooking temperature. During the operation of the furnace, a large amount of residual heat will be continuously dissipated to the outside. At the same time, the evaporation of the glue-cooking liquid will generate a large amount of high-temperature steam. The residual heat dissipated by the furnace and the large amount of residual heat carried by the high-temperature steam are directly lost to the external environment. This not only wastes a lot of thermal energy resources and significantly increases the energy consumption cost of donkey-hide gelatin production, but also leads to an increase in the ambient temperature of the production workshop and a poor production working environment. Meanwhile, in the traditional process of boiling donkey-hide gelatin, room temperature water is usually added directly into the boiling tank. After the room temperature water enters the tank, the temperature of the gelatin liquid inside the tank will drop sharply. On the one hand, the main heating device needs to work continuously at a high load to compensate for the temperature difference and raise the boiling temperature, which greatly increases the workload of the main heating device and keeps the equipment energy consumption high. On the other hand, it will significantly prolong the overall boiling cycle, reduce the production efficiency of donkey-hide gelatin, and the repeated fluctuations in the temperature of the gelatin liquid will affect the uniformity of boiling, indirectly reducing the quality of the finished donkey-hide gelatin. Summary of the Invention

[0003] The purpose of this invention is to provide an energy-saving gelatin-making device for gelatin production that can recover and utilize residual heat during the gelatin-making process.

[0004] The present invention provides an energy-saving gelatin-cooking device for donkey-hide gelatin production, which adopts the following technical solution: Includes a support platform, the top of which is fixedly connected to the glue-cooking main furnace, and a preheating barrel is fixedly connected to the top of the support platform, the interior of which is equipped with a heat-conducting component; The preheating tank is equipped with an air guiding component on its exterior, and the glue-cooking main furnace is equipped with a stirring component inside.

[0008] By adopting the above technical solution, and by setting up a motor, transmission rod, fixed frame, rack, drive rod, fixed tube, rotating bar, connecting bar, stirring plate and gear, multi-dimensional stirring of donkey-hide gelatin inside the main furnace is achieved.

[0010] By adopting the above technical solution and setting a sealing plate, the sliding connection between the stirring plate and the fixed frame can be sealed, thereby preventing the adhesive from flowing into the interior of the fixed frame from the connection between the stirring plate and the fixed frame, and thus preventing the adhesive from affecting the transmission of the rack and gear.

[0016] By adopting the above technical solution and setting up a gas collection component, the internal moisture of the steam can be removed, thereby obtaining drier steam, reducing thermal resistance and heat loss, while avoiding the impact of moisture in the steam on the heat exchange surface, improving the heat exchange effect of the hot gas delivery coil and the water inside the preheating tank, and the separated high-temperature condensate can be returned to the glue-cooking main furnace, thereby avoiding affecting the glue-cooking process.

[0018] By adopting the above technical solution and setting up the first and second heat-insulating pads, the main furnace for boiling gelatin and the preheating tank can be kept warm, preventing the heat inside the main furnace and the preheating tank from dissipating too quickly, thereby avoiding affecting the boiling of donkey-hide gelatin.

[0019] Preferably, the outer wall of the heat conduction circulation pipe is detachably connected to an aerogel felt, the outer wall of the gravity return channel is detachably connected to an aerogel felt, and the outer wall of the hot gas conveying pipe is detachably connected to an aerogel felt.

[0020] By adopting the above technical solution, the aerogel felt can be used to insulate the liquid flowing inside the heat conduction circulation pipe and the gravity return channel, as well as the gas flowing inside the hot gas delivery pipe. This prevents the liquid flowing inside the heat conduction circulation pipe and the gravity return channel, as well as the gas flowing inside the hot gas delivery pipe, from dissipating heat too quickly, thereby avoiding affecting the recovery of residual heat.

[0021] In summary, the present invention has at least one of the following beneficial technical effects: 1. By setting up heat conduction components and gas conduction components, the residual heat generated during the boiling of donkey-hide gelatin can be recovered.

[0034] The implementation principle of this invention is as follows: The main furnace 2 and preheating tank 3 are fixedly installed on the top of the support platform 1, providing overall support. The bottom inner layer of the main furnace 2 is equipped with heating coils, which serve as the main heat source for cooking the donkey-hide gelatin raw materials inside. The waste heat recovery tank 401 is detachably connected to the outer wall of the main furnace 2. A spiral heat conduction channel is opened inside the tank, which is filled with a heat conduction medium. The medium circulates along the spiral heat conduction channel under the action of thermal pressure difference, absorbing the waste heat emitted by the furnace. The waste heat recovery tank 401 is connected to the heat conduction circulation pipe 402 and the gravity return channel 404. The heat conduction circulation pipe 402 extends into the preheating tank 3 and is connected to the top of the heat exchange coil 403. The gravity return channel 404 is connected to the bottom of the heat exchange coil 403, together forming a closed circulation loop. A high-temperature heat-conducting medium enters the heat exchange coil 403 through the heat conduction circulation pipe 402 to preheat the glue-cooking water in the preheating tank 3. After releasing heat and cooling down, the medium flows back to the waste heat recovery tank 401 through the gravity return channel 404 to continuously circulate and recover waste heat. Aerogel felt is installed on the outer walls of both the heat conduction circulation pipe 402 and the gravity return channel 404 to reduce heat loss during transportation. A first insulation pad 10 is detachably installed on the outside of the waste heat recovery tank 401, and a second insulation pad 11 is detachably installed on the outer wall of the preheating tank 3 to insulate the glue-cooking main furnace 2 and the preheating tank 3 respectively, preventing rapid heat loss. The gas guiding component 5 is arranged outside the preheating tank 3. The hot gas conveying pipe 501 conveys the high-temperature steam generated in the glue-cooking main furnace 2 to the hot gas conveying coil 502 on the outer wall of the preheating tank 3. When the steam flows through the coil, it releases heat and further preheats the water in the preheating tank 3. The exhaust gas after heat exchange is discharged through the exhaust pipe 503. The outer wall of the hot gas conveying pipe 501 is connected to the connecting pipe 504. The bottom end of the connecting pipe 504 is threaded with a water collection tank 505. The residual water vapor condensed in the coil is collected in the water collection tank 505 through the connecting pipe 504 to prevent water accumulation from affecting the steam heat exchange efficiency. The stirring component 6 is installed on the top of the glue-cooking main furnace 2. The motor 601 drives the transmission rod 602 to rotate, which drives the fixed frame 603 to rotate synchronously. The rack 604 is fixed on the inner wall of the fixed frame 603, and the drive rod 605 is slidably installed on the outer wall. The drive rod 605 cooperates with the fixed pipe 606 on the inner wall of the top of the glue-cooking main furnace 2, so that the drive rod 605 can move up and down while revolving. The bottom of the drive rod 605 is sequentially connected to a rotating bar 607 and a connecting bar 608. A stirring plate 609 is rotatably mounted on the outer side of the connecting bar 608. A gear 610 fixed on the connecting bar 608 meshes with a rack 604, driving the stirring plate 609 to rotate. This achieves multi-dimensional stirring by combining revolution, rotation, and up-and-down movement, resulting in more uniform mixing and heating of the adhesive. Each stirring plate 609 is equipped with a sealing plate 611 to seal the sliding connection and prevent adhesive from seeping into the transmission structure and causing malfunctions. A spiral blade 612 is fixed to the bottom of the fixed frame 603, which can flip the adhesive at the bottom of the tank upwards to prevent the material from sticking to the wall and burning, while also increasing the discharge speed. The top of the support platform 1 is equipped with a water supply component 7. A water pump 702 draws preheated glue-cooking water from the preheating tank 3 through a water pumping pipe 701, and then quickly delivers it to the glue-cooking main furnace 2 through a water outlet pipe 703. The closed pipeline water supply reduces water temperature loss, and the forced water supply by the water pump 702 improves water supply efficiency and ensures continuous production. A gas collection component 8 is installed inside the glue-cooking main furnace 2. The first gas collection hood 801 and the second gas collection hood 802 work together to collect steam in the tank. The second gas collection hood 802 is connected to the hot gas delivery pipe 501 to complete the steam delivery. The bottom of the second gas collection hood 802 is connected to a first spring telescopic rod 803, and the telescopic end of the first spring telescopic rod 803 is fixed with a corrugated plate 804. An installation pipe 805 is installed on the first gas collection hood 801, and a telescopic spring 806 and a second spring telescopic rod 807 are installed inside the installation pipe 805. The ring 808 at the top of the rotating bar 607 rotates synchronously with the stirring structure, periodically squeezing the second spring telescopic rod 807, causing it to strike the corrugated plate 804, which in turn causes the corrugated plate 804 to vibrate up and down, quickly separating and knocking down water droplets mixed in the steam, thus achieving water-vapor separation, ensuring that the steam entering the air guide assembly 5 is dry, and further improving the heat exchange effect.
