Tianjin Bohai Xinmao Low Temperature Vortex Crushing Unit: Practical Choice for Crushing Thermally Sensitive Materials
Date: 2025-09-08Read: 6
In the fields of traditional Chinese medicine, food, and health products, many materials (such as herbs containing volatile components and thermosensitive enzyme preparations) are temperature sensitive, and the heat generated during conventional crushing processes can easily cause component loss or deterioration. Tianjin Bohai Xinmao R&DLow temperature vortex crushing unitThrough low-temperature control and eddy current crushing technology, the problem of crushing thermosensitive materials has been solved, becoming a commonly used equipment for many enterprises to handle special materials and providing stable and reliable technical support for the material crushing process.
1、 Core Technology Principle: Collaborative Crushing of Low Temperature and Eddy Current
The core feature of the low-temperature vortex crushing unit lies in the combination of "low-temperature environment" and "vortex crushing", accurately adapting to the characteristics of thermosensitive materials:
•Low temperature control mechanismUnit configurationExternal refrigeration systemBefore crushing, the crushing chamber is pre cooled by circulating cold air to maintain a stable temperature of 5-15 ℃ (adjustable according to material requirements); During the crushing process, the refrigeration system continues to operate, promptly removing the heat generated by eddy current impact to prevent material composition changes due to temperature rise (such as loss of volatile components in traditional Chinese medicine and clumping of food raw materials).
•Principle of vortex pulverizationAfter the device is started, the high-speed rotating impeller drives the air to form a strong vortex, and the material is accelerated to high speed under the action of the vortex. The particles collide and shear with each other, while also producing impact friction with the inner wall of the crushing chamber, achieving rapid crushing. This crushing method does not require mechanical extrusion, generates less heat, and, when combined with a low-temperature environment, can largely preserve the active ingredients and original properties of the material. After crushing, the material particle size is uniform (up to 100-200 mesh).
2、 Key structural design: ensuring crushing efficiency and safety
1. Classification and separation system to optimize crushing accuracy
Built in unitAirflow classification deviceThe crushed material enters the grading zone with the airflow, and by adjusting the speed of the grading wheel, the particle size of the finished product can be accurately controlled: fine powder that meets the requirements enters the collector with the airflow, while coarse powder that does not meet the standards is returned to the crushing chamber for re crushing, avoiding material waste caused by "over crushing", while ensuring the consistency of the particle size of the finished product, meeting the fine crushing needs of different industries (such as Chinese medicine micro powder and health product raw materials).
2. Fully enclosed pipeline design to reduce material loss and pollution
Considering that heat sensitive materials are mostly high-value raw materials, the unit adoptsFully enclosed stainless steel pipelineFrom feeding, crushing to collection, the materials are circulated in a sealed environment throughout the entire process, which not only prevents the leakage of cold air from affecting the low-temperature effect, but also avoids pollution caused by the materials coming into contact with the outside air (such as dust flying and impurities mixed in); At the same time, the inner wall of the pipeline has been polished (roughness Ra ≤ 0.6 μ m), with no cleaning dead corners, reducing material residue and lowering the risk of cross contamination between different batches of materials, in compliance with hygiene standards in the food and pharmaceutical industries.
3. Intelligent protection and convenient operation design
•safety protectionUnit configurationTemperature overload protection(Automatic shutdown when the temperature inside the chamber exceeds the set value) andMotor overload protectionCut off the power supply when there are too many materials or foreign objects mixed in, to prevent equipment damage and material deterioration;
•Convenience of operation: AdoptingTouch Control PanelOne click setting of cooling temperature, crushing time, grading wheel speed and other parameters, and real-time display of operating data (such as chamber temperature and humidity, motor current); The device supports one click cleaning function, reducing manual cleaning workload and improving operational efficiency.
3、 Applicable scenarios and daily maintenance
1. Multiple applicable scenarios
The unit is widely used for crushing temperature sensitive materials:
•In the field of traditional Chinese medicine, herbs containing volatile components such as ginseng, deer antler, and angelica can be crushed at low temperatures to retain effective ingredients and improve the utilization rate of herbs;
•Food industry: such as probiotic powder, fruit and vegetable powder, chocolate raw materials, to avoid activity reduction or melting and clumping caused by high temperature;
•In the field of health products, such as protein powder and enzyme preparations, to ensure the activity and nutritional value of materials and meet their needsProduction demand for health products.
2. Key points for standardized maintenance
•Daily maintenanceAfter the crushing is completed, turn off the refrigeration system and wait for the temperature in the crushing chamber to rise to room temperature. Disassemble the collector to clean up residual materials; Check for leaks in the refrigeration system piping to ensure good sealing;
•regular maintenanceCheck the wear of the impeller and grading wheel every week (replace them promptly if they are severely worn to avoid affecting the crushing efficiency); Clean the filter screen of the refrigeration system every month and add or replace refrigerant; Add specialized lubricating oil to motor bearings every quarter to ensure smooth operation of transmission components.
