Description

Technical Field

[0001] This utility model relates to the field of granulation technology, and specifically to a high-purity carotene granulation device. Background Technology

[0002] Carotene is a natural pigment widely found in nature, belonging to the carotenoid family. It is an orange-yellow crystalline substance, mainly found in the roots, leaves, and unripe fruits of plants. Carotene can be converted into vitamin A in the human body, which is very important for human health.

[0003] In the granulation process of carotene production, vertical fluidized bed dryer granulation is usually used. However, the existing single-box air intake means that after granulation and drying, it is necessary to wait for the heater to cool down before blowing cold air from outside into the granulator through an induced draft fan for further cooling. However, since the heater still retains residual heat after being turned off, the cooling time is too long. Prolonged cooling not only affects production efficiency but also causes spots on the surface of the medicine, affecting product quality. Utility Model Content

[0004] This invention provides a high-purity carotene granulation device to address the problems of existing technologies.

[0005] The objective of this utility model can be achieved through the following technical solution: a high-purity carotene granulation device, comprising:

[0006] A granulator, comprising an upper top chamber, a middle fluidized bed granulation chamber, and a lower bottom chamber, wherein the top chamber, the fluidized bed granulation chamber, and the bottom chamber are interconnected and sealed together, and an air inlet is provided on the side wall of the top chamber and an air inlet is provided on the side wall of the bottom chamber.

[0007] An exhaust system, comprising an exhaust pipe connected to the exhaust port pipe and an exhaust fan disposed at the end of the exhaust pipe;

[0008] An air intake mechanism includes a heater, a condenser, and a filter. The heater and condenser are arranged side by side, and their two ends are respectively connected to the air inlet and the filter pipe. A first valve is provided on the pipe of the heater near the filter, and a second valve is provided on the pipe of the condenser near the filter.

[0009] As a further improvement, a filter plate is provided on the side of the filter near the air intake.

[0010] A further improvement is that the filter includes a through-flow primary and secondary filter as well as a high-efficiency filter.

[0011] As a further improvement, a silencer is installed at the front end of the induced draft fan.

[0012] In a further improvement, a cleaning brush is provided at the front end of the filter, the cleaning brush is slidably disposed inside the filter and its cleaning end abuts against the filter plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In actual use, the raw materials are first poured into the granulator. Then, the first valve is opened and the second valve is closed. External air is blown into the granulator through a filter and heater by an induced draft mechanism. The raw materials are heated and pressurized to a semi-fluid state, forming a fluidized bed. At the same time, a mist binder is sprayed in to wet the powder in the container, causing it to condense into loose small particles. These particles are dried under the action of hot air flow. The moisture evaporates continuously, and the powder gradually solidifies to form ideal multi-microporous spherical particles. After granulation, the first valve is closed and the second valve is opened. External air is blown into the granulator through a filter and condenser by an induced draft mechanism to cool the product. This avoids the external gas being affected by the residual heat of the heater during the cooling process, which would prolong the cooling time.

[0015] 2. This utility model filters large particulate impurities in the air through a filter plate, thus extending the service life of the filter. Attached Figure Description

[0024] The granulator 1 includes an upper top chamber 11, a middle fluidized bed granulation chamber 12, and a lower bottom chamber 13. The top chamber 11, the fluidized bed granulation chamber 12, and the bottom chamber 13 are interconnected and sealed together. An air inlet 111 is provided on the side wall of the top chamber 11, and an air inlet 131 is provided on the side wall of the bottom chamber 13.

[0025] The air-expelling mechanism 2 includes an air-expelling pipe 21 connected to the air-expelling port 111 and an air-expelling fan 22 disposed at the end of the air-expelling pipe 21.

[0026] The air intake mechanism 3 includes a heater 31, a condenser 32, and a filter 33. The heater 31 and the condenser 32 are arranged side by side and their two ends are respectively connected to the air inlet 131 and the filter 33 pipe. A first valve 41 is provided on the pipe of the heater 31 near the filter 33, and a second valve 42 is provided on the pipe of the condenser 32 near the filter 33.

[0027] like Figures 1-2As shown, in actual use, the raw materials are first poured into the granulator 1. Then, the first valve 41 is opened and the second valve 42 is closed. External air is blown into the granulator 1 through the induced draft mechanism 2 via the filter 33 and the heater 31. The raw materials are heated and pressurized to a semi-fluid state, forming a fluidized bed. At the same time, a mist-like binder is sprayed in to wet the powder in the container, causing it to condense into loose small particles. These particles are dried under the action of the hot airflow. The moisture evaporates continuously, and the powder gradually solidifies to form ideal multi-porous spherical particles. After granulation, the first valve 41 is closed and the second valve 42 is opened. External air is blown into the granulator 1 through the filter 33 and the condenser 32 via the induced draft mechanism 2 to cool the product. This avoids the external gas being affected by the residual heat of the heater 31 during the cooling process, thus preventing the cooling time from being prolonged.

[0028] As a further preferred embodiment, a filter plate 43 is provided on the side of the filter 33 near the air intake.

[0029] Specifically, such as Figure 2 As shown, the filter plate 43 filters large particulate impurities in the air, extending the service life of the filter 33.

[0030] As a further preferred embodiment, the filter 33 includes a primary and secondary efficiency filter 331 and a high-efficiency filter 332 disposed in a through-flow configuration.

[0031] As a further preferred embodiment, a silencer 221 is provided at the front end of the induced draft fan 22 to reduce noise pollution.

[0032] As a further preferred embodiment, a cleaning brush 44 is provided at the front end of the filter 33. The cleaning brush 44 is slidably disposed in the filter 33 and its cleaning end abuts against the filter plate 43. The filter plate 43 is cleaned by the cleaning brush 44, thereby extending the service life of the filter plate 43.
