Betaine

1. Material Overview

Betaine is an alkaloid widely found in plants and animals. Its chemical structure is similar to that of glycine. It belongs to the quaternary ammonium base class and has the molecular formula C5H11NO2.

Betaine is a quaternary ammonium alkaloid. Anhydrous betaine is a novel fine chemical with wide applications in food, pharmaceuticals, daily chemicals, printing and dyeing, and chemical industries. Anhydrous betaine is a highly efficient and high-quality nutritional additive. Pharmaceutical-grade betaine can be used in the pharmaceutical, cosmetic, food, and juice industries, as well as in dental materials. Betaine can also be used in the fermentation industry.

2. Process Introduction

The drying system is 3^rd-stage airflow fluidized bed drying system, equipped with heaters to facilitate partitioned temperature control. After feeding, the material passes through a dispersing device to prevent local overheating and agglomeration. Inside the dryer, the material undergoes partitioned drying for rapid moisture removal, and is finally discharged through the discharge valve.

3. Technical Advantages

1) Adopting 3^rd-stage independent air intake and three air heat exchangers correspondingly, it can precisely regulate the temperature and air speed in each area for the pre-drying, mid-drying, and post-drying stages of materials, achieving gradient drying with higher temperature control accuracy.

2) The three-stage air intake makes the hot air more evenly distributed in the bed, and the material and the heat medium are in full contact. Combined with the optimized heat load distribution of the independent heat exchanger, the overall heat utilization efficiency is greatly improved and the ineffective energy consumption is reduced.

2) The 3^rd-stage air intake system ensures more uniform distribution of hot air inside the dryer, allowing for sufficient contact between the material and the heat medium. Together with the optimized heat load distribution of the independent heat exchanger, it significantly enhances the overall heat utilization efficiency and reduces ineffective energy consumption.

3) The system structure is simple and the partitioning function is clear. It operates stably in a continuous manner and can adapt to different drying requirements by adjusting the parameters in each area. The equipment has few wearing parts, making daily maintenance and parameter adjustment convenient.

4. Technical Benefit

1) More stable product quality

The zoned gradient temperature control prevents the material from being locally over-dried or under-dried, ensuring high uniformity of moisture content and strong consistency in quality after drying. This significantly reduces the rework loss of non-conforming products and enhances the market recognition of the product.

2) Lower operating costs

The 3^rd-stage heat exchanger accurately distributes the heat load, significantly improving thermal efficiency and reducing energy consumption compared to conventional fluid bed dryer with single air inlet; continuous automated operation reduces manual input, the simple structure results in a low failure rate, and maintenance costs decrease accordingly.

3) Better production adaptability

The partition parameters are adjustable, allowing for flexible adaptation to different production capacities and material drying requirements, and suitable for large-scale continuous production;
