Drying

Industrial Continuously Low Temperature Vacuum Belt Dryer

Product features and description

JNBAN Belt Vacuum Drying (BVD) is a method of continuously distributing liquid raw materials on a conveyor belt under vacuum conditions.The materials are dried with the conveyor belt on the heating plate, and then cooled, embrittled and pulverized. A low temperature drying method. During the whole drying process, the extract is in a vacuum, closed environment, and the drying process is mild(operating temperature 30-135° C), which can maintain its physical properties to the maximum extent and obtain a high quality final product.Since the material is gradually dried under a vacuum for a period of time, the particles obtained by drying have a certain degree of crystallization effect, and at the same time, there are micropores inside from the microscopic structure. After directly pulverizing to the required particle size, the flowability of the particles is very good, and it can be directly tableted or filled with mash, and the particles have good fast solubility.

Belt vacuum dryer working principle

Belt Vacuum Dryer is a method of continuously distributing liquid raw materials on a conveyor belt under vacuum conditions. The materials are dried with the conveyor belt on the heating plate, and then cooled, embrittled and pulverized. A low temperature drying method. During the whole drying process, the extract is in a vacuum, closed environment, and the drying process is mild (operating temperature 30-135° C), which can maintain its physical properties to the maximum extent and obtain a high quality final product.
Since the material is gradually dried under a vacuum for a period of time, the particles obtained by drying have a certain degree of crystallization effect, and at the same time, there are micropores inside from the microscopic structure. After directly pulverizing to the required particle size, the flowability of the particles is very good, and it can be directly tableted or filled with mash, and the particles have good fast solubility.
In addition, a series of parameters can be adjusted online to meet the process requirements of different products, such as the belt speed of the vacuum (solid) belt drying track, the thickness of the layer, the drying temperature, the vacuum degree and etc. The dry product can retain its color, aroma and taste to the utmost extent, and obtain a high quality final product.
Vacuum belt drying technology has a wide range of applications and can be applied to most extracts and solid. Especially for materials with high viscosity, easy to build, thermoplastic and heat sensitive, vacuum belt drying can overcome the shortcomings of too dry and too dense spray drying powder. In addition, a series of parameters such as drying time of vacuum belt drying, feed rate, material thickness, drying temperature and environmental vacuum can be adjusted to suit the process requirements of different products, for heat sensitivity, high concentration, high sugar content, Materials such as high viscosity are also fully tested. At this point, belt vacuum dryers are far superior to spray dryers.

Vacuum belt dryer principle

1. Using digital integrated manufacturing technology, automatic detection and control during dynamic vacuum drying is realized.
2. Adopting digital axial automatic rectification technology to overcome the problem of deviation of the belt during vacuum drying. The belt conveyor system has an automatic online correction function to ensure continuous operation of the equipment for a long time.
3. Adopting new superheated water heating technology, it can be adjusted freely online in the temperature range of (30-135℃ ). Due to the liquid closed-loop heating method, no discharge and no loss, the heating temperature stability and equipment Energy consumption and utilization are superior to traditional steam heating technology.
4. The vacuum degree adopts fully automatic on-line adjustment and control technology, which can optimize the combination of main process parameters such as drying temperature, vacuum degree, feed rate and drying time, so that the working utilization rate of the equipment can reach the most ideal economic benefit.
5. CIP automatic online cleaning system, diversified cleaning methods, can carry out all-round cleaning without any dead angle, the cleaning effect is thorough and fast, in line with GMP requirements.
6. The batching system, the feeding and discharging system can carry out a variety of optimized design, configuration and combination according to different material characteristics, which have met the user’s process requirements.
7. Based on the principle of humanized design: the main body adopts thermal insulation measures to keep the working temperature of the equipment and the operating environment temperature within a suitable range. The inside and outside of the equipment are designed with corresponding detection channels to facilitate daily maintenance and maintenance.
