The biggest challenge in lemon deep processing lies in protecting active ingredients. Vitamin C, lemon essential oil and natural aromatic substances are very sensitive to heat. Once exposed to continuous high temperature, aroma will dissipate rapidly, nutrients degrade, and lemon slices will turn dark and shrink seriously. Hot air-dried lemon slices usually have shriveled texture, weak fragrance and poor rehydration performance, limiting its application in high-end food and beverage industries.
Vacuum freeze-drying technology fundamentally solves these pain points. The equipment freezes lemon raw materials first, then removes moisture via sublimation under high vacuum. The whole process is carried out under low-temperature conditions, so the cell structure of lemon will not collapse. After drying, the material forms a loose porous structure, with full shape, natural yellow colour and strong fresh lemon fragrance. When soaked in water, it can quickly restore the state of fresh lemon slices.
The processing parameters of freeze dryers directly determine finished product quality. Our equipment supports independent adjustment of freezing temperature, vacuum degree and drying duration. Technicians can formulate exclusive freeze-drying programs according to raw material forms: fresh lemon slices, concentrated lemon pulp or lemon powder raw materials.
Our full-series freeze-drying equipment has obtained CE certification, complying with international mechanical safety and food production requirements. The inner chamber adopts food-grade stainless steel, easy to clean and avoid cross-contamination. For fruit and vegetable processors, investing in special freeze-drying equipment for lemons helps to differentiate products from low-end dried fruits, seize the high-end fruit raw material market and obtain higher profit margins.
