The cabinet type supercritical dryer achieves batch reproduction through intelligent process control, and its core mechanism and advantages are reflected in the following aspects:

1、 The core mechanism of intelligent process control

1. Full process automation and data closure

One click fully automatic operation: seamless integration of the production line robotic arm from sample feeding, high-pressure sealing to drying and cleaning, without the need for manual intervention, reducing human errors.

Intelligent program covers the entire process: the built-in program precisely controls the steps of fluid injection, pressure balance, exhaust, etc. All data is recorded in real-time and seamlessly integrated with the production execution system (MES), achieving full traceability from samples to data.

Accurate parameter reproduction: Users can set specific temperature, pressure, time and other parameters, and the equipment ensures consistent experimental conditions through high-precision sensors and closed-loop control systems.

2. Triple security protection and stability guarantee

Mechanical safety valves, electronic alarms, program interlocks: Independent safety systems provide layered protection to avoid batch differences caused by operational errors or equipment failures.

Dust free assembly and high-purity pipelines: The entire process is produced in a dust-free environment, with stainless steel shells and EP grade process fluid pipelines, matched with 0.05 μ m filters to prevent internal and external pollution and ensure batch purity.

2、 The cabinet type supercritical dryer ensures the technical advantage of batch reproduction

1. The essential characteristics of supercritical fluid technology

Uniform permeation and efficient exchange: Supercritical fluids have both gas diffusion and liquid solubility, which can quickly penetrate the microstructure of samples, uniformly remove moisture and volatile components, and avoid local agglomeration or structural damage caused by traditional drying.

No gas-liquid interface damage: no surface tension in supercritical state, eliminating the damage of capillary force to porous material structure and ensuring the consistency of batch structure.

2. Precise temperature control and pressure control system

Gradient control technology: Through intelligent algorithms, temperature and pressure gradient changes are controlled to avoid sudden impacts on the sample and ensure smooth reproduction of the drying process.

High precision sensor: Real time monitoring and feedback of temperature and pressure data inside the chamber, dynamically adjusting parameters to ensure highly consistent environmental conditions between batches.

3、 Application scenarios and effectiveness verification of cabinet type supercritical dryer

1. Semiconductor production line level applications

Wafer drying case: In semiconductor manufacturing, KM-S equipment achieves batch to batch thickness, surface roughness, and other indicators fluctuation of less than 1% through fully automated operation and precise parameter control, meeting the high yield requirements of the production line.

Production line integration capability: The equipment supports seamless integration with the production line robotic arm, incorporating high-speed continuous production cycles, reducing single batch processing time to one-third of traditional methods, while maintaining batch reproducibility.

2. Verification in the field of materials science

Preparation experiment of aerogel: during the drying of silica aerogel, KM-S equipment maintained the integrity of pore structure through supercritical fluid technology, the difference of specific surface area between batches was less than 2%, and the density fluctuation was less than 0.5%, which verified its high reproducibility for complex materials.

Biological sample processing: In the drying of biological samples such as proteins and cells, the equipment avoids structural denaturation under mild conditions, and the difference in activity retention rate between batches is less than 3%, meeting the stringent requirements for consistency in biomedical research.
