Description

Technical Field

[0001] This utility model relates to the technical field of spray drying equipment, and in particular to a spray drying equipment for supernatant in the preparation of salty peptide salt particles. Background Technology

[0002] Salt intake has a significant impact on human health. Salty peptides can be added to salt and processed to form granules, thereby achieving the purpose of producing low-sodium products. In the preparation of salty peptide salt granules, the spray drying of the supernatant (usually a clear solution rich in small molecule peptides and salts obtained after enzymatic hydrolysis and separation) is a key step. Its core objective is to efficiently and stably convert the liquid supernatant into salty peptide salt granules with good fluidity, good solubility, and complete flavor retention. Therefore, a spray drying device for the supernatant in the preparation of salty peptide salt granules is needed.

[0003] Existing methods for preparing salty peptide salt particles commonly use spray drying equipment. In most spray drying equipment, hot air enters the drying equipment from above. After entering, the air comes into contact with the liquid material, and its temperature decreases. As the material continues to fall, the temperature of the liquid material gradually decreases due to the hot air, resulting in incomplete drying. Utility Model Content

[0004] The purpose of this invention is to provide a spray drying device for the supernatant of salty peptide salt particles, in order to solve the problem mentioned in the background art that the commonly used spray drying equipment will not dry completely because the temperature of the liquid material gradually decreases when it comes into contact with the hot air.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray drying device for supernatant in the preparation of salty peptide salt particles, comprising a shell, a feed pipe fixedly connected through the upper end cap of the shell, an atomizer fixedly connected to one end of the feed pipe, an inner liner fixedly installed inside the shell, a spirally distributed connecting hole on the surface of the inner liner, a blower provided on one side of the shell, a filter connected to one end of the blower's air inlet pipe, an electric heater connected to one end of the blower's air outlet pipe, an air inlet pipe fixedly installed at the upper opening of the electric heater, a spiral tube fixedly connected to one end of the air inlet pipe, air outlets evenly distributed on the surface of the spiral tube, and a cyclone separator connected to the discharge port at the bottom of the shell.

[0006] Preferably, the lower end of the inner liner is fitted and fixed to the conical structure at the lower part of the inner side of the shell, the upper part of the inner liner is a conical structure and is fixedly connected to one end of the feed pipe, and the atomizer is located at the upper part of the inner side of the inner liner.

[0007] Preferably, the spiral tube is fixed in the partition between the inner liner and the shell, and its air outlet and connection hole are positioned in a one-to-one correspondence and aligned.

[0008] Preferably, the filter consists of a housing with openings at both ends and a HEPA filter screen inside the housing, and the electric heater is a heating device with built-in alloy resistance wire.

[0009] Preferably, a first connecting ring is rotatably connected to one end of the feed pipe, a first connecting rod is fixedly installed on the outer ring of the first connecting ring, a scraper is fixedly connected to one end of the first connecting rod, a second connecting rod is fixedly connected to the lower end of the scraper, a second connecting ring is fixedly installed on one end of the second connecting rod, and a support frame is connected to the second connecting ring through and bearing one end of the second connecting ring.

[0010] Preferably, the first connecting ring is located at the outer ring of the feed tube between the atomizer and the inner liner, and one end of the support frame is fixedly connected to the inner surface of the shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This spray drying equipment for the supernatant of salty peptide salt granules, by installing a spiral tube in the partition between the inner liner and the shell, and aligning the air outlet of the spiral tube with the connection hole, allows hot air to be introduced into the spiral tube through the air inlet pipe. The hot air is then discharged through the spirally distributed air outlets, ensuring that hot air is constantly blowing from the top to the bottom of the inner liner, fully contacting the material fed in through the feed pipe, thus improving drying efficiency. At the same time, the spirally distributed air outlets are inclined in the inner liner and blow in the same direction, creating a spiral airflow that drives the scraper to rotate, allowing the scraper to remove the fixed particles adsorbed on the surface of the inner liner and fully recover the solid particles.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a spray drying device for supernatant in the preparation of salty peptide salt particles, including a shell 1, a feed pipe 2 fixedly fixed through the upper end cap of the shell 1, an atomizer 3 fixedly connected to one end of the feed pipe 2, an inner liner 4 fixedly installed inside the shell 1, and spirally distributed connecting holes 5 opened on the surface of the inner liner 4, a blower 6 is provided on one side of the shell 1, a filter 7 is connected to one end of the air inlet of the blower 6, an electric heater 8 is connected to one end of the air outlet of the blower 6, an air inlet pipe 9 is fixedly installed at the upper opening of the electric heater 8, a spiral tube 10 is fixedly connected to one end of the air inlet pipe 9, and air outlets 11 are evenly distributed on the surface of the spiral tube 10, and a cyclone separator 18 is connected to the discharge port at the bottom of the shell 1.

[0019] Furthermore, the lower end of the inner liner 4 is fitted and fixed to the conical structure on the lower inner side of the shell 1. The upper part of the inner liner 4 is a conical structure and is fixedly connected to one end of the feed pipe 2. The atomizer 3 is located on the upper inner side of the inner liner 4. Through the setting of the inner liner 4, the lower end is tightly fitted to the conical bottom of the shell 1 to ensure that the material can fall completely into the outlet. The upper conical structure is fixedly connected to the feed pipe 2 to form a sealed atomization chamber. The atomizer 3 is installed in the center of the top of the inner liner 4, and the atomized droplets can be evenly dispersed in the drying chamber.

[0020] Furthermore, the spiral tube 10 is fixed in the partition between the inner liner 4 and the shell 1, and its air outlet 11 corresponds to the position of the connection hole 5 and is aligned. Through the arrangement of the spiral tube 10, the spiral tube 10 is tightly wrapped around the outer wall of the inner liner 4, and its spiral angle is perfectly matched with the distribution of the connection hole 5. When each air outlet 11 is aligned with the connection hole 5, hot air is sprayed into the inner liner 4 at an angle of 15-30 degrees, forming a spiral airflow field that runs through the entire drying chamber.

[0021] Furthermore, the filter 7 consists of a housing with openings at both ends and a HEPA filter inside the housing. The electric heater 8 is a heating device with built-in alloy resistance wire. Through the arrangement of the filter 7 and the electric heater 8, the filter 7 adopts a double-layer HEPA filter, which can remove particles larger than 0.3um. Combined with the PID temperature control system of the electric heater 8, it can heat the air to a stable temperature of 180+5℃.

[0022] Furthermore, a first connecting ring 12 is rotatably connected to the outer ring of one end of the feed pipe 2. A first connecting rod 13 is fixedly installed on the outer ring of the first connecting ring 12. A scraper 14 is fixedly connected to one end of the first connecting rod 13. A second connecting rod 15 is fixedly connected to the lower end of the scraper 14. A second connecting ring 16 is fixedly installed at one end of the second connecting rod 15. A support frame 17 is connected to one end of the second connecting ring 16 through a bearing. When hot air is sprayed into the inner liner 4 through the spirally distributed air outlet 11, the resulting rotating airflow will generate a tangential force on the scraper 14. The scraper 14 is made of polytetrafluoroethylene. The edge of the scraper 14 moves in a circular motion along the inner wall of the inner liner 4, which can effectively scrape off the salty peptide salt particles adhering to the wall surface.

[0023] Furthermore, the first connecting ring 12 is located on the outer ring of the feed pipe 2 between the atomizer 3 and the inner liner 4, and one end of the support frame 17 is fixedly connected to the inner surface of the housing 1. Through the setting of the support frame 17, the scraper 14 can be stably supported from below the housing 1.

[0024] Working principle: First, the supernatant enters the equipment through the feed pipe 2, is atomized into tiny droplets by the atomizer 3, and then sprayed into the drying chamber of the inner liner 4. At the same time, the blower 6 draws in outside air, which is purified by the HEPA filter in the filter 7 and heated into high-temperature hot air by the alloy resistance wire built into the electric heater 8. The hot air is delivered to the spiral tube 10 through the air inlet pipe 9. The spiral tube 10 is spirally distributed in the partition between the inner liner 4 and the shell 1. The air outlets 11 evenly spaced on its surface are aligned with the spirally distributed connecting holes 5 on the surface of the inner liner 4, allowing the hot air to pass through. A spiral airflow is formed and blown evenly from the top to the bottom of the inner liner 4. This design ensures that the atomized droplets are always in full contact with the high-temperature airflow during the falling process. The spiral airflow also drives the first connecting ring 12 to rotate, and drives the scraper 14 to scrape off the adsorbed solid particles along the inner wall of the inner liner 4 through the first connecting rod 13. The second connecting rod 15 and the second connecting ring 16 maintain stable movement under the support of the bearing of the support frame 17. The dried particles fall into the bottom conical structure and finally achieve gas-solid separation through the cyclone separator 18 to obtain a finished product of salty peptide salt particles with good flowability and good solubility.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
