Low Temperature Spray Dryer: 35°C Operation for Heat-Sensitive Materials

This low temperature spray dryer maintains high recovery rates and preserves material activity, operating continuously at 35°C with a 35–100°C range (upgradable to 35–220°C via customizable high-low temp integration). It is ideal for processing protease, camel milk, enzyme preparations, and plant extracts.

description

Laboratory-grade low temperature spray dryer;

Eliminates material rehydration issues

Maximum processing capacity is 50ml/hour;

Inlet air temperature range: 35–140°C; for large-section drying, the QFN-GD series supports an inlet air temperature range of 35–220°C;

Can be upgraded to a combined high and low temperature integrated spray dryer;

This low temperature spray dryer is widely used in universities, research institutes, food, pharmaceutical, chemical enterprises, and laboratories to produce micro-particle powders. It has broad applicability to solutions like emulsions and suspensions, and is suitable for drying heat-sensitive materials including biological products, biological pesticides, and enzyme preparations. Since sprayed materials only experience instantaneous exposure to the drying air system, their active ingredients remain undamaged post-drying. This unit supports both low-temperature atomization drying and combined high-low temperature atomization drying for ambient spray drying.

features

●LABEKS’s innovative drying air system enables low-temperature drying operations

●Real-time PID constant temperature control technology ensures precise temperature regulation across the full operating range, with heating temperature control accuracy of ±1℃

●Utilizes a PID temperature control system

●Fully automatic control: one-button startup; after setting spray process parameters, the peristaltic pump activates automatically once the temperature reaches the preset value, with operational animations displayed on the touch screen for clear process visibility. Press the stop button to trigger a safe, automatic shutdown sequence.

●Manual control mode: easily switch to manual settings to adjust process parameters during experiments as needed

●Equipped with a through-needle nozzle cleaner that automatically clears blockages, with adjustable through-needle frequency

●Shutdown protection function: pressing the stop button halts all operations immediately except the fan, preventing burnout of equipment heating components caused by misoperation (such as forced fan shutdown)

●Spraying, drying, and collection systems are made of high-quality stainless steel, enabling contamination-free drying processes

●Built-in imported oil-free air compressor produces powder with normal particle size distribution, excellent fluidity, and ultra-low noise levels (<60db)

●Two-fluid spray atomization structure; the entire unit is constructed from high-quality stainless steel with a compact design, requiring no auxiliary equipment

●Color LCD touch screen parameter display: monitors inlet air temperature, outlet air temperature, peristaltic pump speed, air volume, and through-needle frequency

●Streamlined, compact structure facilitates easy maintenance and has an extremely low failure rate

●Full stainless steel construction delivers a bright, elegant exterior

●Motor is equipped with reverse phase and overload protection functions

●Feeding volume is adjustable via a dedicated peristaltic pump, with a minimum sample volume of 50ml

●Dried finished powder features high uniformity, with over 95% of particles falling within the same size range

●For viscous materials, the integrated through-needle nozzle cleaner automatically clears blockages, with adjustable through-needle frequency

specifications

Cooling system technical parameters

Design of Microcomputer Precise Constant Temperature Control System

Well-designed and well-designed refrigeration system, high refrigeration efficiency, fast cooling, low noise, low vibration, compressor cascade refrigeration system and heat exchange system to ensure reliable operation and rapid cooling of the instrument

Humanized design: The two-side folding handle is convenient to move the instrument, and the heavy-duty self-locking casters are used for easy movement.

The low temperature tank adopts advanced integral foaming process, which has good thermal insulation performance and effectively reduces the loss of cooling capacity.

The unique circulation design ensures good horizontal and vertical uniformity of the liquid in the tank, the temperature fluctuation is ±0.05°C, and the display resolution is 0.1°C

The inner tank and box are made of high-quality stainless steel and combined with the dry air system to effectively reduce the dry air temperature.
