Recently, the company completed the delivery of two vacuum freeze dryers. After strict pressure testing, vacuum calibration and operation debugging, the equipment was officially loaded and shipped to the customer's production base. This shipment fully reflects the company's reliable manufacturing strength and stable delivery capacity in the freeze-drying equipment industry.
The delivered equipment belongs to industrial large freeze-drying machine. The whole body is made of 316L food-grade stainless steel. Equipped with intelligent PLC control system, high-efficiency refrigeration unit and low-temperature cold trap, the machine realizes automatic pre-freezing, sublimation drying and desorption drying. Under the environment of ultra-low temperature (-40℃~-80℃) and high vacuum (≤10Pa), the internal ice crystals of materials are directly sublimated into water vapor without liquid water participation.
This vacuum freeze drying technology effectively retains the original color, shape and nutritional activity of raw materials. It is suitable for processing fruits and vegetables crisps, freeze-dried coffee, pet freeze-dried snacks, Chinese medicinal materials and biological preparations. Compared with traditional hot air drying, the equipment keeps more than 90% of active nutrients, with good rehydration performance and long shelf life.
In terms of equipment performance, the freeze dryer adopts frequency conversion energy-saving technology and precision constant temperature system with temperature deviation within ±1℃. The low-temperature cold trap efficiently captures water vapor to maintain stable vacuum degree. Customizable freeze-drying curves meet diversified production demands. Meanwhile, the optimized structural design reduces comprehensive energy consumption by 25%-30%.
With the continuous upgrading of the global deep-processing industry, vacuum freeze-drying equipment has become core processing machinery for high-end food and biological raw materials. Relying on independent research and development advantages, cost-effective price and mature after-sales service, domestic freeze dryers realize continuous import substitution and are widely exported to Southeast Asia, the Middle East and other regions.
The smooth shipment of the two freeze dryers marks another solid achievement in the field of drying equipment manufacturing. In the future, the company will keep focusing on intelligent manufacturing, energy saving optimization and technological innovation, and provide reliable freeze-drying overall solutions for global customers.
