AI Technical Summary
When existing ultrafine pulverizers pulverize Nisin heat-sensitive materials, the materials easily lose their biological activity due to high temperature and the increased viscosity leads to equipment blockage.
The material is dried and pulverized using cool air in a sterile environment. A material collection bucket is used instead of a windproof device. A sterile environment is created by condenser and multi-stage filter cartridges to prevent the material from heating up and becoming more viscous.
This effectively avoids material damage and equipment blockage caused by heat, thus improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat-sensitive material pulverization technology, and in particular to an ultrafine pulverization device for Nisin heat-sensitive materials. Background Technology
[0002] Nisin is a natural polypeptide composed of 34 amino acids. It has biological activity but easily loses its biological activity and deteriorates at high temperatures. In addition, finished Nisin products contain some viscous substances such as biological polysaccharides, which will become sticky at high temperatures. Conventional ultrafine pulverizers usually have a long time for materials to stay in the pulverizing chamber, which generates significant heat and causes material damage. At the discharge windproof position, the long-term mechanical rotation will also cause severe heat generation, leading to the loss of biological activity of the material. The increased viscosity of the material will block the equipment. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an ultra-fine pulverizing device for Nisin heat-sensitive materials. It can avoid the material from being damaged due to severe heating and can avoid the material from heating due to mechanical rotation of the windproof device. This can also avoid the material from becoming more viscous due to heating and causing equipment blockage, thereby improving production efficiency and effectively solving the problems in the background art.
[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:
[0005] An ultrafine pulverizing device for Nisin heat-sensitive materials includes an ultrafine pulverizer, a cyclone separator, and a dust collector. The ultrafine pulverizer and the cyclone separator are connected via a first conveying pipe, and the cyclone separator and the dust collector are connected via a second conveying pipe. An air inlet pipe is fixedly connected to the side of the ultrafine pulverizer, and a fan is mounted on the air inlet pipe. A condenser is installed at the port of the air inlet pipe, and an air filter is installed at the air inlet of the condenser. A material collection bucket is detachably connected to the outlet of the cyclone separator.
[0006] Furthermore, the diameter of the air inlet pipe decreases sequentially from left to right.
[0007] Furthermore, the air filter is equipped with a coarse filter element, a fine filter element, and a sterilization filter element on its inner side, arranged sequentially from left to right.
[0008] Furthermore, the opening of the material collection bucket is fixed to the outlet of the cyclone separator by clamps.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This ultrafine pulverizing device for Nisin heat-sensitive materials has the following advantages: it dries the material by removing moisture from the air through the cooling air in a sterile environment, thereby avoiding the material damage caused by severe heating; it replaces the windproof device with a material collection bucket, thereby avoiding the material heating caused by the mechanical rotation of the windproof device, and thus avoiding the phenomenon of equipment blockage caused by the increased viscosity of the material due to heating, thereby improving production efficiency.

Detailed Implementation
[0013] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
[0014] Please see Figure 1-2This embodiment provides a technical solution: an ultrafine pulverizing device for Nisin heat-sensitive materials, including an ultrafine pulverizer 1, a cyclone separator 2, and a dust collector 3. The ultrafine pulverizer 1 and the cyclone separator 2 are connected by a first conveying pipe 5, and the cyclone separator 2 and the dust collector 3 are connected by a second conveying pipe 6. An air inlet pipe 4 is fixedly connected to the side of the ultrafine pulverizer 1, and a fan 9 is mounted on the air inlet pipe 4. A condenser 8 is installed at the port of the air inlet pipe 4, and an air filter 7 is installed at the air inlet of the condenser 8. A material collection bucket 10 is detachably connected to the outlet of the cyclone separator 2. Outside air is first filtered through the air filter 7 to form a sterile environment. Then, the sterile environment air is cooled by the condenser 8. Air enters the ultrafine pulverizer 1 under the action of fan 9. After the ultrafine pulverizer 1 sterilizes the material, the material enters the cyclone separator 2 through the first conveying pipe 5 along with the air. The cyclone separator 2 separates the material from the air. The material enters the material collection bucket 10 for collection. Then, the air is conveyed to the dust collector 3 through the second conveying pipe 6. The dust collector 3 removes dust from the air and discharges it to the next process. The material is dried by the sterile environment and the cooling air removes moisture from the air, thereby avoiding the material from overheating and causing damage. The material collection bucket 10 replaces the windshield, thus avoiding the material from overheating due to the mechanical rotation of the windshield, and thus avoiding the material from becoming more viscous and causing equipment blockage, thereby improving production efficiency.
[0015] The diameter of the air inlet duct 4 decreases from left to right to increase the amount of air entering.
[0016] The air filter 7 has a coarse filter element 12, a fine filter element 13, and a sterilizing filter element 14 installed on its inner side. The coarse filter element 12, the fine filter element 13, and the sterilizing filter element 14 are arranged in sequence from left to right. Air passes through the coarse filter element 12, the fine filter element 13, and the sterilizing filter element 14 in sequence to form a sterile environment, thereby ensuring the cleanliness of subsequent material crushing.
[0017] The opening of the material collection bucket 10 is fixed to the outlet of the cyclone separator 2 by clamp 11, which facilitates the installation or disassembly and cleaning of the material collection bucket 10.
[0018] The working principle of the ultrafine pulverizing device for Nisin heat-sensitive materials provided by this utility model is as follows: The outside air is first filtered through the air filter 7, and then passes through the coarse filter element 12, the fine filter element 13 and the sterilization filter element 14 in sequence to form a sterile environment. Then, the sterile air is cooled by the condenser 8. The cooled sterile air enters the ultrafine pulverizer 1 under the action of the fan 9. After the ultrafine pulverizer 1 sterilizes the material, the material enters the cyclone separator 2 through the first conveying pipe 5 along with the air. The cyclone separator 2 separates the material from the air. The material enters the material collection bucket 10 and is collected. Then, the air is conveyed to the dust collector 3 through the second conveying pipe 6. The dust collector 3 removes dust from the air and discharges it to the next process.
