Vacuum Belt Dryer
Mingyi
The vacuum spiral continuous drying system is a new - type drying system. Its main machine is mainly composed of a power part, a transmission hollow shaft, screw blades, and an outer cylinder jacket. During the drying process, both the screw blades and the outer cylinder jacket are filled with hot media, and the continuous drying of materials is achieved through the full contact and heat transfer between their surfaces and the materials under vacuum conditions.
The hot media can be steam, hot water, or heat - conducting oil. The heating temperature can be controlled in sections according to the moisture content changes of the materials during the drying process to avoid over - baking of the materials. The drying time, heating temperature, and working vacuum degree of the materials can all be automatically adjusted. The drying system has low energy consumption, a high degree of automation, and is easy to operate. At the same time, it realizes the full - closure of the evaporation - related medium, the organized recovery and utilization, saves production costs, and is safe and environmentally friendly.

Applicable to multiple industries
It is suitable for industries such as Chinese and Western medicines, food, bio - engineering, chemical raw materials, health products, and food additives. For example, it can handle traditional Chinese medicine extracts in the pharmaceutical industry, malt in the food industry, and lithium - battery raw materials in the fine chemical industry.
Capable of processing various types of materials
It specializes in low - temperature drying of various liquid paste - like raw materials, especially those with high viscosity, easy caking, thermoplasticity, heat - sensitivity, and those not suitable for spray - drying.
Advanced technology
It adopts a vacuum low - temperature continuous drying method. Liquid raw materials are transported through a feeding pump and evenly distributed on a conveyor belt by a distributing device. High - vacuum is used to sublimate moisture to achieve drying. There are various heating methods, and the temperature can be adjusted according to the characteristics of materials, avoiding damage to heat - sensitive materials caused by high temperatures.
High efficiency and stability
It can continuously produce dry powder within 30 - 60 minutes, with a dry powder output rate of 99%. The dried powder can be automatically packaged or enter subsequent processes. It is equipped with an online automatic cleaning system, meeting GMP requirements and ensuring stable product quality.
Low operating cost
The operating cost is only one - third of that of vacuum ovens and spray - drying, and one - sixth of that of freeze - drying. Long - term use can save a large amount of energy costs.
Low labor cost
Only two operators are required at most, reducing labor input.
