A professional natural spice deep-processing enterprise signed a customized large industrial freeze dryer order, specially designed for mass lyophilization of single spices and mixed compound aromatic raw materials including chili, ginger slices, garlic granules and star anise.
Traditional hot-air drying destroys volatile aromatic essential oil inside spices, leading to weak fragrance of finished seasonings; the factory decided to adopt vacuum freeze dryer low-temperature freeze-drying technology to retain complete spice natural aroma.
Our technical team widened the spacing between internal trays of this batch freeze drying machine, leaving enough air circulation gap for spice particles and slices, avoiding poor sublimation caused by dense spice stacking during lyophilization.
Different from small bench-top freeze dryer only for new spice formula testing, this industrial lyophilizer supports continuous 24-hour stable operation, matching the factory's daily large-batch spice raw material processing rhythm.
We optimized the dehumidification and condensation system of the vacuum freeze dryer, adapting to high moisture fresh ginger, garlic and chili raw materials, shortening total spice freeze-drying cycle and improving daily processing output.
After equipment installation and commissioning, the factory's freeze-dried spice products will own stronger natural fragrance and longer storage life, greatly improving market competitiveness of its natural seasoning series.
