Description

Technical Field

[0001] This utility model relates to the field of hydrolyzed feather powder processing technology, specifically to an energy-saving steam drying equipment for hydrolyzed feather powder. Background Technology

[0002] The main methods for processing feathers include high-temperature and high-pressure hydrolysis, chemical hydrolysis, enzymatic hydrolysis, puffing, and microbial degradation. High-temperature and high-pressure hydrolysis is currently the most widely used method. The most common practice of high-temperature and high-pressure hydrolysis is to use a boiler to generate hot steam and then pass the hot steam into the hydrolysis tank. Under the high temperature and high pressure environment, the structure of the feathers in the hydrolysis tank will change, and the protein will be hydrolyzed.

[0003] In a Chinese patent for a hydrolyzing tank for producing hydrolyzed feather powder (patent number: CN112515035A), the device includes a tank body, a tank cover, and a heating device for the hydrolyzing tank. The heating device includes a thermal oil heating device, a steam heating device, and a control device. During production, the thermal oil heating device is always in operation. When the temperature detected by the temperature sensor is lower than a preset lower threshold, the controller controls the steam heating device to start working. When the temperature detected by the temperature sensor is higher than a preset upper threshold, the controller controls the steam heating device to stop working. This device can ensure the process temperature of the hydrolyzed feather powder production equipment. It can realize that hydrolysis and drying are completed in the hydrolyzing tank. However, the steam from the hydrolyzed feather powder in this device is directly discharged to the outside, resulting in heat energy waste and insufficient energy saving. Moreover, there is no function to stir the hydrolyzed feather powder, resulting in uneven heating of the hydrolyzed feather powder and poor drying effect. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up a circulating steam drying mechanism, allows the heating mechanism to heat the water in the water tank to generate steam.

[0021] Please see Figures 1-5This embodiment provides an energy-saving steam drying device for hydrolyzed feather powder, which includes a tank body 1 and an inner tank 2 fixed in the tank body 1. The upper side wall of the tank body 1 is fixedly connected to a feed valve port 3 that communicates with the inner tank 2 to add hydrolyzed feather powder. The inner tank 2 is equipped with a multi-shaft stirring mechanism. The outer side wall of the tank body 1 is fixedly connected to a circulating steam drying mechanism that communicates with the inner tank 2. The bottom of the tank body 1 is fixedly connected to a discharge valve port 4 that communicates with the inner tank 2 to discharge hydrolyzed feather powder. Both sides of the bottom of the tank body 1 are fixedly connected to support legs 5 for stable support.

[0022] The circulating steam drying mechanism includes a water tank 6 fixed to one side of the tank body 1. A heating mechanism is located at the bottom of the water tank 6. A first induced draft fan 7 is connected to the upper part of one side of the water tank 6. An air guide pipe 8 is connected to the outlet end of the first induced draft fan 7. One end of the air guide pipe 8 extends into the tank body 1 and is connected to a spiral coil 9. The spiral coil 9 is sleeved on the outside of the inner tank 2. The end of the spiral coil 9 away from the air guide pipe 8 is connected to a return air pipe 10. A second induced draft fan 11, connected to the inner tank 2, is located on the upper side wall of the tank body 1. A circulation pipe 12 is connected to the upper end of the second induced draft fan 11. The return air pipe 10 is connected to the circulation pipe 12. The lower end of the circulation pipe 12 extends into the water tank 6. When needed... When steam drying the hydrolyzed feather powder in the inner tank 2, the heating mechanism is activated to heat the water in the water tank 6 to generate steam. At the same time, the first induced draft fan 7 is activated to guide the steam through the air guide pipe 8 into the spiral coil 9, which can steam heat and dry the hydrolyzed feather powder in the inner tank 2. Then, the steam flows back to the water tank 6 through the return air pipe 10 and the circulation pipe 12. Meanwhile, the steam generated during the drying of the hydrolyzed feather powder in the inner tank 2 is turned on by the second induced draft fan 11, which guides the steam through the circulation pipe 12 to the water tank 6. The heat of the steam can be recycled, thereby reducing the energy consumption required for heating and achieving the effect of energy saving. Since it is a closed-loop circulation system, there is no need to worry about the stability of the water return.

[0023] like Figure 3 and Figure 5As shown: The multi-shaft stirring mechanism includes a cover 13 fixed to the upper side wall of the tank 1. A motor 14 is fixedly connected to the upper side wall of the cover 13. The main shaft of the motor 14 passes through the cover 13 and is fixedly connected to a first stirring shaft 15. Two first gears 16 are fixedly connected to the first stirring shaft 15. Two symmetrically arranged second stirring shafts 17 are inserted into and rotatably connected to the upper side wall of the tank 1. A second gear 18 is fixedly connected to the upper end of each of the two second stirring shafts 17. The two first gears 16 are connected to the two second gears 18 through a gear chain 19. A screw is fixedly connected to the first stirring shaft 15 located in the inner tank 2. The spiral stirring blades 20 and the two second stirring shafts 17 are fixedly connected with stirring teeth 21. When the hydrolyzed feather powder enters the inner tank 2 for steam drying, the motor 14 is started, which drives the two first gears 16 on the first stirring shaft 15 to rotate. Since the two first gears 16 are driven by the two gear chains 19 and the two second gears 18, they drive the two second stirring shafts 17 to rotate simultaneously. This drives the spiral stirring blades 20 and the two sets of stirring teeth 21 to stir the hydrolyzed feather powder in the inner tank 2, making the hydrolyzed feather powder heat more evenly, improving the drying efficiency, and thus achieving the effect of energy saving.

[0024] like Figure 3 As shown: The lower end of the first stirring shaft 15 is fixedly connected to a spiral feed rod 22. The lower end of the spiral feed rod 22 extends into the discharge valve port 4. When the discharge valve port 4 is opened, the spiral feed rod 22 rotates, which can drive the hydrolyzed feather powder in the inner tank 2 to be discharged in a stable manner.

[0025] like Figure 3 As shown: The inner bottom wall of the inner tank 2 is rotatably connected to the lower end of the second stirring shaft 17 through a bearing seat, so that the second stirring shaft 17 rotates stably.

[0026] like Figure 4 As shown: The heating mechanism includes an electric heater 23 fixed to the bottom of the water tank 6 and a heating element 24 fixed to the inner bottom wall of the water tank 6. The electric heater 23 and the heating element 24 are electrically connected. When the electric heater 23 is started, it supplies power to the heating element 24 to heat the water in the water tank 6 and generate water vapor.

[0027] like Figure 1 As shown: A control panel 25 is fixedly connected to one of the support legs 5. The control panel 25 is electrically connected to the multi-axis stirring mechanism and the circulating steam drying mechanism respectively. This means that all electrical equipment of this device is electrically connected to the control panel 25. The circuit involved is existing technology, which can be fully implemented by those skilled in the art, and there is no need to elaborate.

[0028] Working principle: When it is necessary to steam dry the hydrolyzed feather powder in the inner tank 2, the electric heater 23 is started to power the heating element 24 to heat the water in the water tank 6 and generate steam. At the same time, the first induced draft fan 7 is started to guide the steam through the air guide pipe 8 into the spiral coil 9, which can steam heat and dry the hydrolyzed feather powder in the inner tank 2. Then, the steam flows back to the water tank 6 through the return air pipe 10 and the circulation pipe 12. Meanwhile, the steam generated during the drying of the hydrolyzed feather powder in the inner tank 2 is turned on by the second induced draft fan 11 and guided through the circulation pipe 12 to the water tank 6. The heat of the steam can be recycled, thereby reducing the energy consumption required for heating and achieving the effect of energy saving.

[0029] When the hydrolyzed feather powder enters the inner tank 2 for steam drying, the motor 14 is started, which drives the two first gears 16 on the first stirring shaft 15 to rotate. Since the two first gears 16 are driven by the two tooth chains 19 and the two second gears 18, they drive the two second stirring shafts 17 to rotate simultaneously. This drives the spiral stirring blades 20 and the two sets of stirring teeth 21 to stir the hydrolyzed feather powder in the inner tank 2, making the hydrolyzed feather powder heat more evenly, improving the drying efficiency, and thus achieving the effect of energy saving.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
