New and efficient equipment, looking forward to the international market; Innovate and leap forward, quality and sail far. On April 24, 2025, the new XSD-FD-20 (1㎡) household freeze dryer developed and produced by our company successfully completed the factory quality inspection and set off for export to Vietnam, leading a new trend in fruit and vegetable delicacies. In recent years, the scale of Vietnam's agricultural product exports has continued to expand. In particular, dried fruits and food products have been highly favored by the international market due to their long shelf life and high added value. However, traditional drying techniques have problems such as low efficiency and nutrient loss. Vietnamese enterprises urgently need efficient and energy-saving freeze-drying equipment to enhance product competitiveness and export standards. In addition, the volume of fruit trade along the China-Vietnam border is huge. However, due to frequent congestion at ports, freeze-drying technology can reduce the transportation pressure of fresh fruits and extend their shelf life. Our company's independently developed household freeze dryer precisely meets the needs of small and medium-sized processing enterprises and family workshops in Vietnam with the following features: 1. Unique structural design: The equipment compartment of our company is made of 304 stainless steel, formed by machine extrusion in one piece without welding, which is anti-corrosive and sterile. The internal heating shelf is made of graphene heat-conducting board material, which ensures more uniform heating of the product materials and better drying effect. The door of the drying chamber is made of explosion-proof glass material, which is of high strength, leak-proof and has strong vacuum performance. 2. Customizable equipment: The equipment can be customized according to the customer's requirements (temperature, size, appearance). 3. Easy operation: The integrated square design makes the whole machine small in size, with strong sealing performance, convenient to use and high efficiency. Pulleys can be installed at the bottom of the equipment for convenient movement and positioning. True-color touch screen, with high control accuracy, stable performance, simple program and quick to get started. 4. Cloud-based remote control: The operating system software is automated and can be remotely controlled via a mobile APP on a mobile phone or a PC. It also features an automatic alarm function with emergency status alerts and early warnings. The device is equipped with a USB interface for downloading operation data. 5. Low noise: Our company's equipment is designed as an integrated unit. The refrigeration unit and vacuum pump are all built-in installed (while the equipment of our competitors' products is all external units or vacuum pumps, which are inconvenient to use and generate a lot of noise). Moreover, there is sound-absorbing cotton inside, providing excellent sound insulation. 6. Large water capture capacity: The cold trap of our company's equipment is designed on the inner side or back, providing a large overall space. It comes with a built-in freezing function, ensuring uniform water capture and energy conservation. Sieno Freeze-drying Technology Research Institute (Jiangsu) Co., Ltd. is located in Zhenglu Industrial Park, Tianning District, Changzhou City. It mainly engages in the production and sales of vacuum freeze dryers, refrigeration equipment, cold storage projects, etc. The company now holds over 50 freeze-drying patent certificates, and also has ISO9001 and CE certification qualifications.

On June 27, 2025, a 40-square-meter medium-sized freeze-drying equipment integrating advanced technology was successfully loaded onto a vehicle in our company's production workshop and officially set off for the Russian Federation. This high-performance freeze dryer will be delivered to a leading local Russian enterprise specializing in the deep processing of high-end fruits. Its core mission is to produce high-quality mango freeze-dried products for the Russian market. The 40-square-meter freeze dryer dispatched this time is one of the representative models of our company's mature medium and large-scale freeze-drying solutions. After conducting rigorous market research and technical comparisons, the Russian customer finally selected this model of equipment, precisely because of its efficient production capacity, stable temperature control accuracy, and outstanding retention ability for heat-sensitive nutrients such as vitamins and flavor substances. The equipment will be used to process fresh mangoes. Through advanced vacuum freeze-drying technology, the moisture in the mangoes will be directly sublimated and removed in a low-temperature (-40℃ to -50℃ or even lower) and highly vacuum environment. This process can preserve the natural color, rich aroma, sweet taste and abundant nutrients of mangoes to the greatest extent. The mango freeze-dried slices/pieces produced will meet the growing demand for healthy, natural and portable snacks in the Russian and surrounding markets with their light weight, long storage life, high rehydration capacity and "fresh-locking" characteristics. Its technical parameters directly point to the special challenges of freeze-drying mangoes: ** Large-capacity drying chamber ** : With a freeze-drying area of 40 square meters, it can handle up to 400-450 kilograms of raw materials in a single batch, significantly enhancing the processing capacity of the products. ** Advanced Structural Design ** : The core components such as the drying chamber, cold trap, refrigeration, and vacuum system are designed as an integrated unit, eliminating the need for additional transfer freezing and allowing operations within the same drying chamber. Ensure a smooth and orderly freeze-drying process and reduce energy consumption under the overall process. ** Precise Temperature Control and Vacuum System ** : Integrating a high-efficiency refrigeration unit and a high-precision vacuum system, it ensures that the temperature and vacuum degree of the product remain precise and stable throughout the freeze-drying process (pre-freezing, maintenance, sublimation drying), and retains the original nutrients in the product to the greatest extent. ** Full-process intelligence ** : Equipped with an Internet of Things remote monitoring platform, it enables cloud-based optimization of process parameters and reduces the risk of manual intervention.
