Freeze-dried Coffee Machine

With the upgrading of national consumption quality, instant coffee has long since shed its stereotypical label of "bitter and cheap." Freeze-dried coffee, with its pure taste, rich aroma, and preservation of original flavor, has become the mainstream trend in the coffee consumption market.

Unlike traditional freeze-drying coffee machines

Compared to coffee produced by traditional high-temperature spray drying, freeze-dried coffee occupies a core share of the high-end instant coffee market due to its advantages such as fresh taste, high nutrient retention, rapid reconstitution, and ultra-long shelf life. The creation of high-quality freeze-dried coffee is inseparable from professional, precise, and stable freeze-drying production equipment. Our company has been deeply involved in the research, development, production, and manufacturing of freeze-drying equipment for many years, focusing on the pain points and needs of the coffee deep processing field. We have created professional freeze-drying equipment suitable for standardized, large-scale, and refined production of freeze-dried coffee.

Core Technological Advantages

With our core technological advantages, full-category capacity specifications, and stable equipment quality, we have become a core partner of many freeze-dried coffee production companies, helping them create high-quality coffee products and seize market opportunities.

The core quality advantage of freeze-dried coffee stems from vacuum low-temperature freeze-drying technology. Our self-developed and self-produced freeze-drying equipment precisely controls the core freeze-drying process, fundamentally solving the drawbacks of traditional coffee processing and giving freeze-dried coffee an exceptional product quality. 

Traditional spray drying processes require high-temperature dehydration, which completely destroys more than 17 aromatic compounds in coffee, resulting in the loss of core active nutrients such as chlorogenic acid and caffeine. This not only leads to a weak aroma and bitter taste but also significantly reduces the product's added value. Our freeze-drying equipment uses low-temperature vacuum sublimation drying technology, operating at low temperatures throughout the process. It can stably control the processing temperature below 0℃. First, through precise temperature-controlled pre-freezing technology, the coffee concentrate is slowly pre-frozen at a rate of 1~2℃/min, forming uniform and delicate micro-ice crystals. This prevents the ice crystals from damaging the microstructure of the coffee concentrate, eliminating problems such as clumping and uneven appearance.

Sublimation Drying Stage

During the core sublimation drying stage, the equipment precisely controls the vacuum level to maintain between 15 and 25 Pa, and the shelf heating rate is stabilized at 0.5℃/min. This allows the ice crystals in the coffee concentrate to directly sublimate into water vapor under vacuum, skipping the liquid-to-gas conversion process and completely avoiding flavor and nutrient loss caused by high-temperature processing. The entire process retains over 95% of the coffee's original flavor compounds and active nutrients, maximizing the restoration of the coffee beans' natural sweet and sour texture and rich flavor. After brewing, it quickly reconstitutes, leaves no residue, and has a rich aroma, closely resembling the quality of freshly ground coffee, perfectly meeting current consumer demand for high-quality instant coffee.

Freeze-drying Equipment Empowers All Aspects

In addition to its core advantages of optimal aroma and freshness preservation, our freeze-drying equipment provides comprehensive support to coffee producers in terms of production stability, product qualification rate, and cost control. The equipment is equipped with an intelligent automated control system, using precise numerical control programs to regulate the entire freeze-drying process. Parameters for the pre-freezing, sublimation, and desorption drying processes can be set with a single button and run automatically, eliminating the need for repeated manual adjustments and effectively avoiding parameter errors caused by manual operation. The freeze-drying temperature, vacuum level, and drying time are maintained consistently for each batch of coffee, completely solving the industry problem of inconsistent product taste and appearance in mass production. This ensures stable and controllable product quality for businesses, significantly enhancing brand reputation and market competitiveness.

Optimize Freeze-drying Equipment Systems To Extend Product Shelf Life.

Simultaneously, the equipment optimizes the vacuum circulation system and cold trap water-capturing structure, resulting in more thorough dehydration. It controls the moisture content of freeze-dried coffee to extremely low standards, giving the product an exceptionally long shelf life. After vacuum packaging, it can be stably preserved for several years at room temperature, resisting moisture damage and flavor loss, greatly reducing storage and transportation losses. In terms of energy consumption, the equipment uses energy-efficient vacuum components and insulation structures, significantly reducing energy consumption compared to traditional freeze-drying equipment. The automated and efficient operation mode also shortens the production cycle per batch, effectively reducing labor costs and energy consumption, helping manufacturers achieve multiple goals of quality improvement, efficiency enhancement, and cost reduction. Furthermore, the equipment's inner tank and material-contacting parts are made of food-grade stainless steel, which is corrosion-resistant, easy to clean, and residue-free, fully complying with food production hygiene standards and meeting the standardized safety production requirements for coffee products.

Establish Long-term Cooperative Relationships With Freeze-drying Companies

With its superior equipment quality, comprehensive production capacity, and robust after-sales support, our freeze-drying equipment has become the preferred choice in the freeze-dried coffee industry. We have long-standing and stable strategic partnerships with numerous well-known domestic and international freeze-dried coffee producers and food processing companies. Our clients cover several coffee processing hubs in Yunnan, Guangdong, Fujian, Shandong, and other regions, serving emerging coffee brand manufacturers, traditional large-scale food processing enterprises, and cross-border coffee product suppliers.
