Constant Temperature Electric Heated Vacuum Mixer

Product Overview

This constant temperature electric heated vacuum mixer is designed for controlled processing of viscous pastes, slurries, adhesives, coatings, pigments, fragrances, cosmetics, pharmaceutical materials, and auxiliary compounds. Vacuum mixing removes entrained gas during agitation, helping prevent bubbles and improving the consistency of the finished material. Integrated heating provides adjustable temperature control from 50°C to 150°C, helping reduce viscosity and supporting smoother, more uniform processing.

The equipment is suited to research and production preparation tasks in pharmaceuticals, fine chemicals, electronics, new energy, cosmetics, coatings, and materials development. Its 50 ml to 1000 ml mixing capacity supports laboratory-scale formulation, sampling, process optimization, and small-batch preparation where repeatability and visual process control are important.

A transparent, injection-molded polycarbonate vacuum vessel provides direct visibility of the material and mixing condition. The robust vessel tolerates impacts and substantial changes in vacuum conditions, while reliable seals, precision needle valves, and adjustable mixing speed support stable operation under demanding laboratory workflows.

Key Features

• Bubble Reduction Through Vacuum Mixing: Vacuum operation removes gases from the material while it is being agitated, reducing visible bubbles and supporting a more homogeneous mixture for subsequent coating, dispensing, testing, or application.

• Adjustable Constant Temperature Heating: The integrated heating function can be set anywhere from 50°C to 150°C. Controlled heating helps improve the flow behavior of viscous materials without requiring a separate heating vessel.

• Broad Variable Speed Range: Mixing speed is adjustable from 30 to 466 rpm, allowing operators to select a suitable agitation condition for different viscosities, batch sizes, and formulation stages.

• Impact Resistant Polycarbonate Vessel: The vacuum tank is injection molded from polycarbonate. It is lightweight, transparent, resistant to knocks and drops, and capable of handling significant vacuum changes during operation.

• Direct Visual Process Monitoring: High vessel transparency allows users to observe material movement, dispersion, wetting, and bubble removal without opening the chamber or interrupting the process.

• Fine Vacuum Flow Adjustment: A dedicated precision needle valve enables fine adjustment of both air intake and exhaust flow. This helps prevent sudden pressure changes that could damage or blow away sensitive material.

• Reliable Sealing Arrangement: A high-quality silicone rubber ring seals the upper and lower vessel sections without requiring sealing grease. The rotating seal between the vacuum vessel and mixing shaft is also designed for dependable operation.

• Convenient Installation and Material Handling: The vessel is easy to install, load, unload, and clean between batches, supporting efficient laboratory work and frequent formulation changes.

• Visible Vacuum Status: A vacuum gauge mounted on the side of the vessel allows operators to check the vacuum condition at any time during the mixing cycle.

• Quick Change Pneumatic Connections: The needle valve and tubing use quick-change fittings. Imported soft nylon tubing supports convenient connection and flexible bench-level installation.

Applications

Technical Specifications

The maximum vacuum of -0.1 MPa provides the operating basis for bubble-reduced mixing of viscous materials. Because the vacuum condition can be monitored through the side-mounted gauge and adjusted through the precision needle valve, operators can manage pressure changes with greater control during loading, evacuation, and mixing. Fine adjustment of inlet and exhaust flow is particularly useful when handling lightweight, sensitive, or easily disturbed materials.

The heating range is freely adjustable between 50°C and 150°C. This range allows users to select a process temperature according to material viscosity and formulation requirements. Heating can make thick slurries, pastes, adhesives, coatings, and similar compounds easier to agitate, improving contact between components and helping the mixer maintain a consistent process condition. Temperature control accuracy is specified as 1%, providing a defined control standard for repeatable laboratory preparation.

The 50 ml to 1000 ml capacity range gives the system practical flexibility for research and small-batch work. It can accommodate small samples for formulation screening while also supporting larger laboratory batches for process verification. The variable 30 to 466 rpm speed range allows users to adapt agitation intensity to material behavior, batch volume, and the stage of mixing. The specified torque values of 21.3 kg·cm at 333 rpm and 6.9 kg·cm at 25 rpm provide useful reference points when evaluating mixing performance for viscous materials.

The vessel is manufactured from injection-molded polycarbonate, combining low weight with high transparency and impact resistance. The material allows direct inspection of the mixing state and is designed to tolerate substantial changes in vacuum conditions. The upper and lower vessel sections use a silicone rubber sealing ring that does not require sealing grease, helping simplify routine setup and maintenance. The rotating seal around the mixing shaft is designed for reliable vacuum retention during operation.

The pneumatic arrangement includes a dedicated precision needle valve, quick-change fittings, and soft nylon tubing. These components support convenient connection and controlled gas flow adjustment. The operating ambient temperature range is -25°C to 40°C, and the equipment is designed for connection to a 220 V ±10% power supply. The mixer measures 380 × 290 × 580 mm, while the separate temperature controller measures 260 × 220 × 125 mm. The total equipment weight is 17 kg, supporting practical placement in a laboratory or development workspace.
