BOTH-China Leading freeze drying machine Manufacturer: Achieving CE Certification for Global Market Access

Jiading, Shanghai Apr 11, 2026 (EMWNews.com) – BOTH-China Leading freeze drying machine Manufacturer: Achieving CE Certification for Global Market Access

In the modern food processing landscape, where consumer demand for high-quality, nutritious, and safe products is paramount, the role of advanced preservation technology has never been more critical. Freeze-drying, a sophisticated process known for its ability to maintain the nutritional integrity, flavor, and structure of sensitive foods, sits at the forefront of this technological evolution. The deployment of this technology, however, hinges on the reliability and precision of the equipment used. For processors seeking dependable solutions, the assurance provided by internationally recognized quality management systems is a key differentiator. In this context, BOTH INSTRUMENT & INDUSTRIAL EQUIPMENT (SHANGHAI) CO., LTD., an ISO 9001-certified entity with over 15 years of experience, positions itself as a noteworthy participant in the field, recognized as a China Leading freeze drying machine Manufacturer dedicated to supporting the food industry’s stringent demands for quality and safety.

The Science and Significance of Freeze-Drying

Freeze-drying, scientifically known as lyophilization, is a multi-stage dehydration process. Unlike conventional thermal drying methods that apply heat and can degrade a product’s cellular structure, flavor, and nutritional content, freeze-drying operates under low-temperature and vacuum conditions. The process begins with deep freezing the product, solidifying its water content into ice. Subsequently, a powerful vacuum is applied, and controlled heat is introduced. This allows the ice to transition directly from a solid to a vapor–a process called sublimation–bypassing the liquid phase entirely. The final stage involves secondary drying to remove any residual bound water molecules.

The benefits of this gentle yet effective method are manifold. For food processors, it translates into products with exceptionally long shelf lives without the need for chemical preservatives, as the removal of water inhibits microbial growth and enzymatic reactions. Critically, the porous structure left after sublimation allows for excellent rehydration properties, meaning freeze-dried fruits, vegetables, meats, and even complete meals can regain much of their original texture and taste. This makes the technology indispensable for producing high-value ingredients for instant soups, camping foods, space missions, and premium snacks where flavor and nutrient retention are non-negotiable.

Engineering Excellence: The BSFD, BTFD, and PFD Series

To meet the diverse needs of the global market, BOTH has developed specialized equipment series that cater to different scales of production and material requirements. At the industrial level, Production Scale Vacuum Freeze Dryers are defined by a freeze-drying area of no less than 5 m2 and a processing capacity of at least 50 kg per batch. These machines are widely utilized across pharmaceutical, food, chemical, and biological sectors.

Within this industrial category, the BSFD Series Freeze Dryer represents a leap in operational efficiency. The BSFD series features a freeze-drying chamber where materials can be directly pre-frozen. This eliminates the need for manual movement of materials, allowing the entire pre-freezing and drying process to be completed within a single integrated environment. Beyond traditional materials, the BSFD series is highly effective for liquid products, heat-sensitive materials, and products with high activity requirements or industrial raw materials.

Conversely, the BTFD Series Freeze Dryer is engineered for specific economic and material-based applications. Unlike the BSFD, the BTFD series does not include an integrated pre-freezing function. It requires manual operation to transfer materials to the drying chamber after they have been pre-frozen in a separate unit. This makes the BTFD series particularly suitable for easier-to-process products such as fruits, vegetables, seafood, flowers, meat, and pet food, as well as Chinese herbal slices.

For those in the research and development phase, the Pilot Scale Vacuum Freeze Dryer (PFD Series) offers a bridge between the lab and full-scale production. The PFD series has revolutionized the traditional drying process by automating sublimation and preventing material pollution. These dryers feature shelf heating and programming capabilities, enabling the machine to “remember” specific freeze-drying curves. Additionally, the PFD series comes equipped with a USB flash drive output function, allowing researchers to BOTH’s Approach to Freeze-Dryer Engineering: VFD, HFD, RFD, DFD & SFD Series

BOTH’s technical philosophy is fully embodied in its VFD, HFD, RFD, DFD and SFD series of freeze-drying machines. The company has carried out targeted optimizations to address two long-standing pain points in both industrial and household production: spatial efficiency and operational control. Each series features differentiated product characteristics to meet the diverse needs of different users for freeze-drying equipment.

In addition to efficient space saving, the entire range is equipped with an integrated energy storage system that significantly enhances production stability. This system effectively buffers against power grid fluctuations, providing a more stable operating environment for precision freeze-drying processes. Furthermore, BOTH has integrated real-time remote monitoring capabilities into its professional freeze-dryers. Technical personnel can remotely monitor critical parameters such as temperature, vacuum pressure and cycle progress in real time, enabling remote control, fault diagnosis and data logging, which strongly supports process optimization and quality assurance.

Wide Application Scenarios & Quality Assurance System

BOTH freeze dryers cover a full range of categories: industrial grade (BSFD/BTFD), pilot scale (PFD), commercial type (VFD/SFD), and household type (HFD/RFD/DFD). They feature extremely versatile applications and can process various materials including fruits such as berries and mangoes, vegetables, candies, meat, pet food, Chinese herbal medicines, liquid extracts, and even cosmetic facial masks. The equipment meets the demands of large-scale food production, health products, cosmetics and other industries.

Corporate credibility is built on verifiable quality standards. BOTH is certified under the ISO 9001 international quality management system, with standardized management throughout design, production and service. It also holds multiple authoritative certifications such as CE, GMP and ASTA, forming a complete quality assurance system.
