Product Introduction

The ZLGJ-50FD is an electrically heated pilot-scale freeze dryer featuring a freeze-drying area of ​​0.6 square meters (distributed across six specialized shelves); it achieves a minimum cold trap temperature of ≤-60°C and has a water-trapping capacity exceeding 8 kg.

Core Advantages

The equipment features a freeze-drying chamber, shelves, and a condenser all constructed from AISI 304 stainless steel, utilizing a patented internal welding process. With an internal surface roughness of Ra ≤ 0.6 μm and shelf flatness exceeding ±0.5 mm/m, the design eliminates sanitary dead zones, facilitating easy cleaning and sterilization—making it an ideal choice for vial freeze-drying processes in the biopharmaceutical industry. The shelf temperature is adjustable between -40°C and +70°C (no-load), with steady-state temperature uniformity better than ±1°C; the condenser can cool from +20°C to -40°C within 30 minutes (reaching a minimum temperature below -60°C) and offers a water-trapping capacity exceeding 8 kg. The system employs a Mitsubishi PLC and a Kinco touchscreen interface, supporting both manual and automatic operation modes through an intuitive, user-friendly interface. It includes functions for sensor calibration and intelligent freeze-drying endpoint indication; all critical production parameters are recorded in real-time and can be exported via USB with a single click, easily meeting international production management requirements for process validation and compliance traceability.

With an integrated design (approx. 880×700×1470mm, 447kg), it’s compact, easy to transport and place, no complex assembly needed. The acrylic transparent door lets you monitor the entire freeze-drying process in real-time. The U-shaped coil condenser boasts strong ice-capturing capability and a compact structure, paired with natural defrosting for simple, efficient cleaning and maintenance—saving you plenty of labor costs.

Application Fields

This equipment is widely used in the biopharmaceutical sector (for the freeze-drying of vial-packaged products such as antibodies, vaccines, and diagnostic reagents—compatible with 12mm, 16mm, and 22mm vials, with minimum capacities of 4,246, 2,388, and 1,263 vials, respectively), the high-end food industry (small-batch production of freeze-dried fruits, vegetables, health supplements, and pet food), and the field of new materials (drying of nanomaterials, enzyme preparations, etc.). It is particularly well-suited for the freeze-drying of heat-sensitive, oxidation-prone, and high-value materials, and is also applicable to scientific research, industrial process optimization, and production process validation.

Frequently Asked Questions

Q: What should be kept in mind for daily equipment maintenance?
A: Routine maintenance involves simply cleaning the shelves and cold trap, checking the vacuum pump oil level and vacuum pressure, keeping the unit ventilated and dry, preventing debris accumulation, and monitoring high-pressure or vacuum alarms. These steps ensure proper component operation and extend the equipment's service life.
Q: Which vial specifications are compatible with the equipment, and what are the loading capacities?
A: It accommodates three common vial sizes: 12mm (2ml), 16mm (5ml), and 22mm (10ml). The respective loading capacities are ≥4,246, ≥2,388, and ≥1,263 vials, fully meeting small-batch freeze-drying needs for vials in the biopharmaceutical sector.
Q: Is the equipment difficult to operate? Can beginners get up to speed quickly?
A: Operation is very simple! It features PLC touchscreen controls, supports both manual and automatic modes, and includes preset common freeze-drying processes that can be started with a single touch. We provide detailed operation manuals (in Chinese and English) and video training, allowing beginners to master the system quickly without prior professional experience.
Q: How should equipment malfunctions be handled?
A: The equipment features a real-time alarm function, allowing you to view alarm logs and quickly pinpoint the cause of a fault. You can also contact our after-sales team for 24/7 online support to resolve issues rapidly, minimize production losses, and ensure smooth operations.
