Overview:

Definition: The MZG series pulsating vacuum dryer is a new type of vacuum drying equipment, primarily used for low-temperature, efficient drying treatment of materials. In a vacuum state, it adjusts the vacuum degree instantaneously through the pulsating function at regular intervals, causing the material's drying state to continuously change, thereby achieving rapid drying.

Structure: Generally composed of four major systems - the drying main body, pulsation system, vacuum system, and control system. The drying main body includes the housing, drying rack, and drying trays, used for placing and drying materials; the pulsation system generates pulsating air flow, causing the vacuum level to fluctuate continuously; the vacuum system is responsible for gas extraction and moisture removal, maintaining the vacuum state within the chamber; the control system monitors and controls the entire drying process.

Principle:

Place the material to be dried on the drying tray, then insert the tray into the drying machine's chamber.

Start the vacuum system, using the vacuum pump to exhaust moisture, forming a vacuum state within the workspace. Under vacuum conditions, the boiling point of water decreases, allowing the moisture in the material to evaporate rapidly at lower temperatures.

Simultaneously, the dryer's heating system heats the jacket of the housing and the inner panel of the drying rack, transferring heat to the material, thereby raising its temperature.

During the drying process, the pulsation system定时调节 vacuum levels momentarily, causing continuous formation and bursting of air bubbles within the material. Post-bubbling, the material is rapidly defoamed using clean air, and the compressed gas carries away a large volume of evaporated gases through the vacuum pump's intake, accelerating the evaporation and removal of moisture within the material, thereby enhancing the drying efficiency.

Advantages:

Hot plate heating with excellent temperature uniformity, even heat distribution of materials, and high drying efficiency.

Utilizing a water ring and Roots double-stage vacuum unit, material boils quickly under high vacuum, preventing carbonization and ensuring no loss in content.

The equipment utilizes the pulsating bubble principle, achieving high vacuum and low temperature conditions. When the material froths, it automatically breaks the bubbles, preventing overflow, and the dried material forms a honeycomb structure. The subsequent process is easy to crush, resulting in a high yield.

Advantages over traditional drying equipment:

High drying efficiency, over 200% more efficient than traditional equipment, significantly reducing drying time. Energy consumption savings of over 80% compared to hot air circulation ovens. Products have better uniformity and quality after drying, with improved color. Equipped with online cleaning or immersion cleaning functions. Mobile material cart design for easier cleaning. Pulse defoaming design for materials prone to bubbling, and explosive drying method for materials that are not easily defoamed, fully utilizing the latent heat of steam and the water-absorbing properties of its sub-saturated steam. Automatic control system with a user-friendly interface, allowing for segmented parameter settings to achieve more complex process flows, ensuring optimal drying efficiency and results.

Application:

The Low-Temperature Pulsed Vacuum Dryer is a low-temperature drying equipment designed for traditional Chinese medicine extracts with high sugar content, low temperature, prone to overflow, foaming, and oxidation. The equipment can use steam, hot water, or thermal oil as a heat source and employs a pulsing bubble technique to break the mucous film formed on the material surface, enabling rapid evaporation of internal moisture. It addresses issues such as high energy consumption and low efficiency in traditional Chinese medicine extract equipment, as well as the mismatch with pharmaceutical production processes. Currently, it is an efficient and energy-saving product that integrates drying and pulsing functions, serving as a high-efficiency replacement for outdated models.
