Development Trends of Various Food Dryers in China

Drying is a critical process in food preservation, significantly extending the shelf life and maintaining the quality of dried products. The performance of drying equipment directly influences the final quality and market value of the dried food. In recent years, China has made remarkable progress in developing advanced, multi-functional, energy-efficient, and adaptable drying technologies tailored for various industries. Zhejiang Huafeng Refrigeration Equipment Factory has introduced a series of steam-based vegetable drying and dewatering machines designed specifically for the export of dehydrated vegetables. These systems utilize high-temperature steam to heat air, producing hot, dry air above 120°C. They can effectively dehydrate a wide range of vegetables, including cabbage, spinach, garlic, onions, green bean sprouts, pumpkin slices, radish slices, and potato chips. The system features adjustable temperature control, energy-efficient fans, automatic condensate drainage via a steam trap, and a high-quality stainless steel material tank that meets strict food hygiene standards. Changzhou No. 2 Drying Equipment Factory has developed the third-generation DWT series dehydrated vegetable dryer, suitable for large-scale continuous drying of root vegetables, leafy greens, and other materials like garlic slices, pumpkins, carrots, konjac, yams, bamboo shoots, horseradish, onions, and apples. This equipment has been widely adopted by hundreds of companies across Zhejiang, Shandong, and Fujian provinces. The Heilongjiang Academy of Agricultural Machinery and Engineering Research Institute has developed a hot air dehydration system ideal for vegetables, wild plants, edible fungi, and tea. The system uses conveyor belts to move pre-treated materials into the dryer, where moisture is reduced by 75–80% in the high-temperature zone and further lowered to 3–5% in the low-temperature zone, ensuring optimal drying results. Changzhou Yangtze River Drying Equipment Co., Ltd. has introduced a closed-loop superheated solvent vapor fluidized bed dryer, which integrates drying and solvent recovery. This technology is particularly effective for alcohol-soluble materials and is used in food, pharmaceuticals, and chemical industries. It offers high drying efficiency, energy savings, and environmental benefits. Nanjing Yatai Institute of Microwave Energy has developed microwave vacuum freeze-drying equipment suitable for vegetables, royal jelly, and ginseng. This system heats materials evenly without dead zones, reduces drying time by 2–3 times, and preserves nutrients and functional components. It is ideal for heat-sensitive materials such as health products, fruits, and herbs. Shenyang Aerospace Xinyang Frozen Equipment Manufacturing Co., Ltd. produces the LG-125 vacuum freeze-drying equipment, capable of drying food through sublimation under vacuum conditions. This method preserves the original color, flavor, and shape of the product while retaining most of its nutrients. The dried products are highly valued in international markets. Changzhou Huayuan Drying Equipment Co., Ltd. has developed the CT series drum dryer, an internal heating conduction type that achieves up to 80–90% thermal efficiency. It is suitable for drying liquids, pastes, and viscous materials such as meat products, dairy items, and starch. Jiangsu One-Step Drying Equipment Co., Ltd. has developed several advanced drying systems, including the HG roller scraper dryer, DWT closed-loop belt dryer, HLG high-speed mixing granulator dryer, and DLB60 multi-functional coating dryer. These systems offer improved efficiency, reduced energy consumption, and compliance with GMP standards, making them ideal for food, pharmaceutical, and chemical industries. Sichuan Agricultural Machinery Research and Design Institute has developed a mobile grain dryer that uses crop straw gas as a heat source, reducing drying costs and preventing spoilage in grain-producing areas. The system features multiple independent drying bins, enhancing efficiency and effectiveness. Nanjing Institute of Agricultural Mechanization has successfully applied microwave technology for tea drying, replacing traditional methods. This technique ensures even heating, faster processing, and enhanced tea quality, increasing the levels of beneficial compounds like tea polyphenols and amino acids. The result is better color, aroma, and overall quality of green tea.

Panel Turnover Machine

• This type of machine is operated manually. It is suitable for small-scale production or occasions where the workload is not heavy. Operators need to physically turn over the panels by hand or with simple tools attached to the machine. Although it requires more physical effort, it is relatively inexpensive and can meet basic turnover needs.
• Advantages: Low cost, simple structure, easy to maintain. Disadvantages: Low efficiency, labor-intensive.

• Semi-automatic panel turnover machines combine manual and mechanical operations. They usually have some mechanical assists, such as hydraulic or pneumatic systems, to make the turnover process easier. Operators still need to perform some operations manually, but the workload is significantly reduced compared to manual machines.
• Advantages: Moderate cost, improved efficiency compared to manual ones. Disadvantages: Still requires some manual intervention, not fully automated.

• Automatic panel turnover machines are highly advanced and are designed for large-scale production. They are equipped with sophisticated sensors, control systems, and mechanical mechanisms that can automatically detect and turn over panels without human intervention. These machines can handle a high volume of panels in a short time and ensure consistent quality and accuracy.
• Advantages: High efficiency, accurate turnover, suitable for mass production. Disadvantages: Higher cost, complex maintenance requirements.
