Description

Technical Field

[0001] The utility model relates to the technical field of gelatin production, and more specifically, to a hot air drying device for gelatin production. Background Art

[0002] Gelatin does not exist naturally in nature. It is a non-uniform polypeptide mixture obtained from animal skin, bones and other collagen-containing tissues after a series of chemical treatments. Gelatin needs to be dried using drying equipment during the production process.

[0003] At present, a Chinese patent with a publication (announcement) number of CN216770104U discloses a hot air drying device for edible gelatin production, which includes a drying box, a No. 1 support frame, a hot air generating device, an exhaust device, a conveyor belt, and a scraping mechanism. The No. 1 support frame is arranged in the drying box, and a plurality of transmission belts are arranged horizontally and parallelly on the No. 1 support frame. The transmission directions of two adjacent conveyor belts are opposite, and the lower conveyor belt receives the transmission objects on the upper conveyor belt. When the hot air drying device for edible gelatin production is working, the gelatin is transmitted to the drying box through the top transmission belt. The drying box is connected to the hot air generating device. A circulating drying conveyor belt is arranged in the drying box, so that the edible gelatin is transmitted from the top conveyor belt to the lower conveyor belt on the conveyor belt at one time, and is gradually dried during the transmission process, and finally transported out by the output device. However, during work, workers are required to manually spread the gelatin raw materials to the top conveyor belt, that is, the spreading amount is controlled by the workers themselves, but the accuracy of manual spreading is poor, which leads to gelatin accumulation on the conveyor belt. Excessive accumulation leads to uneven drying of the gelatin material, affecting the drying effect of the device. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 As shown, a hot air drying device for gelatin production according to an embodiment of the utility model includes a shell 1, the shell 1 is formed with an inner cavity 10, and the inner cavity 10 has a feeding section 2 and a drying section 3, two conveyor belts 30 are correspondingly arranged above and below the drying section 3, the conveyor belt 30 located at the bottom extends to the outside of the shell 1, the drying section 3 is located between the two conveyor belts 30 and is also provided with a hot air conveying mechanism, the shell 1 is located at the top of the drying section 3 and is provided with a spreading mechanism, the spreading mechanism is used to spread the gelatin evenly on the conveyor belt 30.

[0019] When in use, two conveyor belts 30 are correspondingly arranged in the upper and lower parts of the drying zone 3. The upper conveyor belt 30 transmits from left to right, and the lower conveyor belt 30 transmits from right to left and extends to the outside of the shell 1. When working, the upper and lower conveyor belts 30 work and the spreading mechanism spreads the gelatin raw material evenly to the left end of the upper conveyor belt 30. The gelatin raw material is transmitted from left to right by the upper conveyor belt 30 to complete the first drying process. After reaching the left end of the upper conveyor belt 30, the gelatin raw material falls to the right end of the lower conveyor belt 30, and then is transmitted from right to left by the lower conveyor belt 30 to complete the second drying process. The first drying process and the second drying process are both transmitted hot air by the hot air conveying mechanism.

[0020] The utility model provides a material spreading mechanism to accurately control the material spreading amount, so as to spread the gelatin raw material evenly to the conveyor belt 30, thereby ensuring the drying effect of the device on the gelatin raw material.

[0021] The material spreading mechanism includes a barrel 20, a hopper 21 connected to the top of the barrel 20, and a discharge channel 22 connected to the bottom of the barrel 20 and extending to the top of the conveyor belt 30; a material passing cavity 23 is formed in the barrel 20, and a material dividing roller 24 is rotatably arranged in the material passing cavity 23, a material storage trough 25 is opened on the material dividing roller 24, and a feeding interval is formed between the material storage trough 25 and the inner wall of the barrel 20.

[0022] During use, the gelatin raw material is put into the hopper 21. The distributing roller 24 rotates to make the storage tank 25 periodically pass through the connection between the barrel 20 and the hopper 21, and the connection between the barrel 20 and the blanking channel 22. When the storage tank 25 passes through the connection between the barrel 20 and the hopper 21, the gelatin raw material in the hopper 21 automatically falls into the storage tank 25. When the storage tank 25 passes through the connection between the barrel 20 and the blanking channel 22, the gelatin raw material in the storage tank 25 automatically falls into the blanking channel 22, realizing the intermittent blanking of the gelatin raw material.

[0023] The barrel 20 has an opening 4, and a barrel cover 40 is installed at the opening 4. A driving shaft 41 is rotatably arranged on the inner bottom wall of the barrel 20. One end of the driving shaft 41 penetrates and extends outside the barrel 20 and is connected to a power source. An assembly hole 42 adapted to the driving shaft 41 is provided at the center of the distributing roller 24, and the distributing roller 24 is detachably connected to the driving shaft 41 through the assembly hole 42.

[0024] During use, the barrel cover 40 is fixedly connected to the barrel 20 through fasteners such as screws. When the distributing roller 24 needs to be installed, the barrel cover 40 is opened, the assembly hole 42 of the distributing roller 24 is aligned with the driving shaft 41 and pushed in. The inner end of the driving shaft 41 has a resisting ring. The distributing roller 24 is pushed until its inner end abuts against the resisting ring. At this time, the fastener (nut or other fastening parts) is tightened with the outer end of the driving shaft 41 to complete the installation of the distributing roller 24. To disassemble the distributing roller 24, the reverse operation can be performed;

[0025] The driving shaft 41 is drivingly connected to an external power source through a coupling (the power source is preferably a servo motor);

[0026] The distributing roller 24 is detachably connected to the driving shaft 41, which is convenient for daily maintenance or replacement, and is also convenient for replacing the distributing roller 24 with a storage tank 25 of different capacities;

[0027] A number of partition plates 26 are equidistantly and spacedly distributed in the blanking channel 22.

[0028] During use, the blanking channel 22 is divided into multiple separate channels by the partition plates 26, avoiding the accumulation of the gelatin raw material in the blanking channel 22 and affecting the paving effect of the blanking channel 22.

[0029] The hot air conveying mechanism includes a conveying box 31. The left end of the conveying box 31 is connected with a conveying pipe 32, and the conveying pipe 32 is connected and communicated with an external hot air blower. A number of air outlet pipes 33 are equidistantly and spacedly arranged on the upper and lower sides of the conveying box 31.

[0030] During use, the external hot air blower sends hot air into the conveying box 31 through the conveying pipe 32, and then discharges it into the housing 1 through each air outlet pipe 33;

[0031] Furthermore, air outlet pipes 33 are arranged in rows on both the upper and lower sides of the conveying box 31. The upper air outlet pipes 33 mainly preheat the belt of the upper conveyor belt 30. Gelatin raw materials falling from the feeding channel 22 fall onto the preheated conveyor belt 30, thereby effectively improving the drying effect on the gelatin raw materials. When the raw materials fall from the upper conveyor belt 30 to the lower conveyor belt 30, the hot air output by each air outlet pipe 33 on the lower side of the conveying box 31 is directly directed towards the conveyance of the gelatin raw materials. Therefore, the temperature of the gelatin raw materials slowly rises during the process from the upper conveyor belt 30 to the lower conveyor belt 30. Thus, the drying process of the gelatin raw materials is gentler.

[0032] Among them, a scraping member is arranged on the top surface of the conveying box 31 below the upper conveyor belt 30 to scrape off the gelatin raw materials adhered to the conveyor belt 30.

[0033] Among them, the conveying pipe 32 is communicated with an external hot air blower to supply hot air into the conveying box 31. The hot air blower is installed at the rear end of the housing 1 (not shown in the figure), and the hot air blower and its connection mode with the conveying pipe 32 are prior arts and will not be elaborated here.

[0034] The pipe diameters of the two side air outlet pipes 33 gradually increase from left to right.

[0035] During use, since the interface of the conveying pipe 32 is at the right end, the arrangement of the pipe diameters of the air outlet pipes 33 can make the air output of each air outlet pipe 33 more uniform.

[0036] The electrical components appearing in this text are all electrically connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer that plays a control role.
