Description

FDR series features

The FDR series freeze dryers are positioned around "large-scale production + full-category compatibility," with a daily processing capacity ranging from 20 to 5000 kg per single machine, perfectly filling the gap in medium-to-large capacity scenarios compared to other series.

The products feature a round chamber design with a matte polished surface, resulting in a uniform texture and no visual color difference. The chamber body is reinforced with ribs, significantly improving compressive strength and torsional resistance during lifting, making it suitable for continuous production.

Advantages in adaptation

Unlike the FDC series' integrated freezing design, the FDR series models with a capacity of 500 kg and above innovatively adopt a "split layout" the product freezing process is completed in the quick-freezing room, while the freeze-dry process takes place inside the chamber.

The two are connected by a monorail and a suspended trolley for rapid material transfer, ensuring production continuity while improving process flexibility. Particularly prominent: Its applicability breaks through industry limitations, enabling "freeze-drying of everything,"

covering all categories of materials including fruits, vegetables, meat, seafood, dairy products, cooked food, candy, ice cream, coffee, pet food, herbal, tea, animal and plant specimens, and cultural relics. 

It adopts a modular design, allowing for rapid assembly via flanges and bolts, making installation efficient and convenient.

For different factory environments, functional zoning and equipment layout can be flexibly planned, and a value-added service of providing a free customized layout plan within 24 hours is offered, ensuring optimal equipment and site fit.

Core Technologies and Process Highlights

High-efficiency heat transfer

Radiant heat transfer technology: Equipped with a high-efficiency radiant heat transfer plate with a thermal property of up to 160W/m.K , which is 10 times that of 304 stainless steel (14W/m.K ), significantly improving production efficiency after extensive experimental verification, freeze-dried candy can be dried in just 3 hours, providing core support for large-scale production.

Durable design:The shelf thickness reaches 200% of the industry average, greatly extending the service life; the tray adopts a one-piece die-casting process and offers multiple material options such as aluminum, 304 and 316L stainless steel.

The non-right-angle design completely eliminates cleaning dead corners and is more suitable for the cleanliness requirements of food, medicine and other fields.Space and operation optimization:

The door has been upgraded to a multi-axis linkage revolving door, which significantly reduces the opening radius and the installation area is reduced by 70% compared to the track-side sliding door;

a large-size tray design is adopted, which not only improves material conveying efficiency but also significantly reduces labor costs; an optional CIP (clean-in-place) system is available, which also has SIP (sterilization in place) and drying functions to meet high clean production standards.
Energy-saving innovation from diverse energy sources

Energy-saving innovation from diverse energy sources

The FDR series split-type freeze dryer deeply integrates multiple proprietary patented technologies, focusing on energy consumption optimization: it supports various energy inputs such as steam, solar energy, natural gas, geothermal energy, coal, and air energy, and is equipped with the company's independently developed waste heat recovery and reuse technology to minimize electricity consumption and achieve green and low-carbon production. The unit's components are highly integrated, achieving optimal space utilization.

Precise control and intelligent management

Continuing the core control advantages of the high-end series, the temperature control probe achieves a control accuracy of ±1℃, and features dual modes of constant temperature linear heating and distributed staged temperature control. The software includes intuitive and easy-to-understand preset parameters covering the freeze-drying needs of most materials, eliminating the need for frequent adjustments. It supports editable recipes, allowing for precise setting of both temperature and time. Parameter modifications require password authorization, fully complying with FDA regulations and ensuring batch-to-batch quality consistency. Deeply integrating IoT technology with Siemens PLCs, it enables real-time monitoring and remote, precise intervention throughout the freeze-drying process, comprehensively strengthening the quality control line.

Top configuration and quality assurance

Key component advantages

It adopts a self-developed freeze-drying-specific vacuum pump and Roots pump, which has a fast pumping speed, low energy consumption, and performance that is significantly better than similar products from German Leybold and Japanese Ulvac ; the vacuum inlet of the 500kg and above models is equipped with a special filter to effectively filter particulate matter, moisture and contaminants, which not only protects the vacuum pump and extends its service life, but also ensures the cleanliness and safety of the freeze-dried products.

Structural protection upgrade

The unit frame is treated with a special anti-rust and corrosion-resistant paint process to adapt to complex industrial environments;

Each functional module is highly integrated to maximize functionality within a limited space, while reducing maintenance difficulty through scientific layout.

Applicable Scenarios and Core Value

The FDR series, with its core values of "full-category adaptability, large-scale production, low consumption and high efficiency, and customized services," is perfectly suited for large-scale production scenarios such as food processing plants, pet food companies, herb processing bases, and agricultural product deep processing projects. Whether it's high-volume freeze-drying of fresh produce, standardized food processing, or long-term preservation of special materials (such as specimens and cultural relics), it can precisely meet the needs. Through the synergy of diverse energy adaptability, efficient heat transfer technology, and intelligent control systems, it helps enterprises improve production efficiency while reducing overall costs, achieving the dual goals of large-scale production and high-quality output.
