TECHNICAL FIELD
The invention relates to the technical field of protein drying, in particular to a spray dryer for drying protein.
BACKGROUND
The production of protein powder (such as milk powder, protein powder, peptide powder, etc.) often uses a spray dryer. The basic principle of the spray dryer is that hot air and atomized materials are simultaneously passed into the drying tower, and the atomized materials are quickly evaporated after contacting with the high-temperature hot air, and become dry products in a very short time.
However, the current spray dryer is prone to the phenomenon of material sticking to the wall during the drying process. After the material sticking to the wall, it is impossible to discharge effectively. It needs to be shut down regularly for cleaning.
After cleaning, the material needs to be reprocessed, which increases the process and cost of protein powder processing and reduces the production efficiency. Therefore, a spray dryer for protein drying is needed to solve the above problems.
SUMMARY OF THE INVENTION
The purpose of the invention is to provide a spray dryer for drying proteins to solve the problems in the prior art proposed in the above background technology.

DETAILED DESCRIPTION OF THE INVENTION
In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following will further elaborate on the present invention in conjunction with specific implementation methods.
Please refer to Figures 1-5. The present invention provides the following technical solutions:
A spray dryer for protein drying, including a spray host 6, a charging barrel 1 and a Muno pump 2, the input pipe of the Muno pump 2 is connected with the discharge port of the charging barrel 1, the output pipe of the Muno pump 2 is connected with Ce the feed port of the spray host 6, the spray host 6 is connected with a steam heater 4 through a pipe, the steam heater 4 is connected with a blower 3, the discharge port of the spray host 6 is connected with a cyclone separator 7, the outlet port of the cyclone separator 7 is connected with a pulse bag dust collector 8, and the pulse bag dust collector 8 is connected with a silencer 9 and an induced draft fan through a pipe 10;
Muno pump 2 conveys the materials in barrel 1 to spray host 6, which atomizes the materials into spray host 6, and then enters the interior. The steam heater 4 cooperates with blower 3 to feed high-temperature hot air into spray host 6.
The discharge port of the cyclone separator 7 is connected to an ultrasonic dispersion chamber 5, in which an ultrasonic generator with an ultrasonic frequency range of 15-40KHz is used. When the ultrasonic dispersion chamber 5 processes solid particles, longitudinal waves are generated in the medium due to the cavitation effect of the ultrasonic wave, which alternately compresses and expands the area. The change in pressure will form bubbles in the medium. These bubbles have a larger surface area during the expansion process, increasing the diffusion of gas. During this process, molecules will collide violently, producing shock waves, causing an instantaneous increase in temperature and pressure in the local area, completing the granulation process without the need for adding granulating agents, saving production costs.
The spray host 6 is provided with an inner wall cleaning mechanism and a material grinding mechanism, which are used for cleaning and grinding the materials adhered to the inner wall of the spray host 6; The inner wall cleaning mechanism comprises a driving plate 61, a scraping impeller 62 and a main gear 64 which are rotationally connected to the interior of the spray host 6. The driving plate 61 is vertically rotationally connected with a scraping impeller 62, the edge of the scraping impeller 62 contacts the inner wall of the spray host 6, the inner wall of the driving plate 61 is installed with a gear ring 67, the upper end key of the scraping impeller 62 is connected with a main gear 64 which is meshed with the gear ring 67, and the top of the spray host 6 is installed with a drive motor 68 which is used to drive the rotation of 074 the driving plate 61; The scraping impeller 62 and grinding roller 63 are arranged in pairs, and the paired scraping impeller 62 and grinding roller 63 are evenly distributed on the circumference of the driving plate 61. 5 The material grinding mechanism is installed on the driving plate 61 and is located on one side of the inner wall cleaning mechanism. The grinding mechanism comprises two grinding rollers 63 that are rotatably connected to the driving plate 61.
The upper ends of the two grinding rollers 63 are respectively keyed to a driven gear 65 and a driven gear 266 that mesh with each other. The driven gear 165 meshes with the main gear 64; The grinding mechanism can grind the material scraped off by the inner wall cleaning mechanism into powder, eliminating the need for stopping the cleaning and reprocessing process; The drive plate 61 is equipped with a baffle 69 for auxiliary scraping materials to enter the grinding mechanism. The baffle 69 can prevent the splashing of scraped materials from causing the materials to be unable to be ground.
The working process of the present invention 1s as follows:
The materials in the charging drum 1 are conveyed to the spray host 6 through the
Moono pump 2, and then enter the interior of the spray host 6 after atomization. High temperature hot air is introduced into the spray host 6 through the cooperation of the steam heater 4 and the blower 3. After the atomized materials contact the high temperature hot air, the water evaporates rapidly, realizing the drying of the materials.
The dried materials and air flow enter the cyclone separator 7 for separation, and the air flow enters the pulse bag dust remover 8 for filtering again, and is discharged through the silencer 9. The dried materials enter the ultrasonic dispersion room 5 for granulation.
During the drying process, the drive motor 68 is started at the same time, and the drive motor 68 drives the drive plate 61 to rotate, so that the drive plate 61 drives the scraped impeller 62 installed on it to move synchronously. The scraped impeller 62 rotates under the driving effect of the main gear 64 and the ring gear 67, so as to scrape the materials adhering to the inner wall of the spray host 6, and throw the 07% scraped materials between the two grinding rollers 63. The grinding roller 63 rotates through the driving of the main gear 64, driven gear I 65 and driven gear II 66, so as to grind the scraped materials.
Although embodiments of the present invention have been shown and described, it can be understood by those skilled in the art that multiple variations, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is limited by the accompanying claims and their equivalents.
