Process freeze dryer FD-FP series

for the food industryfor the pharmaceutical industryfor nutraceutical products

Overview
Vacuum freezing and drying (freeze drying / lyophilization) technology for industrial dehydration of food and biological materials. Freeze-dried products retain shape and volume, show good rehydration, preserved color, flavor and nutrients, and have extended shelf life. This split-type freeze dryer is suitable for vegetables, fruits, condiments, extracts and selected pharmaceutical/biological materials.

DESCRIPTION OF FRUIT FREEZE DRYER
Vacuum freezing and drying is an advanced dehydration process. Compared with conventional drying methods, products processed by lyophilization have a longer shelf life, better rehydration and retain original appearance. The dried product remains essentially unchanged in volume and shape and has a porous structure. Applicable to vegetables, fruits, condiments, aquatic products, biologicals, medicines and beverages.

Scope of application

• Herbal medicines and health supplements: ginseng, Gastrodia, Panax notoginseng, Poria, Dendrobium, Cordyceps, bird’s nest, bee products, deer products.
• Extracts and concentrates: anthocyanin, Ginkgo extract, nutrient solutions, biological reagents, enzymes, antibiotics.
• Aquatic products, meat, poultry, eggs: sea cucumber, abalone, shellfish, shrimp, fish, beef, mutton, chicken and egg products.
• Forest and specialty products: edible fungi, wild vegetables, bamboo shoots, asparagus, pollen, konjac.
• Fruits, vegetables, soups and beverages: strawberry, raspberry, mango, lemon, apple, peach; onion, garlic, sweet potato; instant soups, coffee, juices.

Main Advantages of Fruit Freeze Dryer

• Separate pre-freezing and drying chambers to improve process efficiency and shorten cycle time.
• Space-class aluminum alloy separator with double-sided radiation heating for good temperature uniformity and emissivity.
• Mixed refrigerant system providing lower freezing point, improved heat exchange efficiency and long service life.
• Drying-curve optimization algorithm to control product heating rate and vacuum during drying stages.
• Patented gas diversion and control design for effective moisture capture and high drying efficiency.
• Pallets stamped from aviation-grade corrosion-resistant aluminum alloy with special surface treatment; each drying chamber includes two holding trays.
• Industrial embedded touch screen with SH-HPSC-III modular controller for precise system control.
• FD-MANAGER control system for saving multiple process recipes and real-time adjustment for process optimization.
• Manual and automatic operation modes for R&D and batch production.
• Accurate sensor calibration to ensure long-term process parameter stability.
• User-level and password management for controlled operations.
• Optional FD host computer system for long-term data logging (operation data, curves, alarms) to support traceability. Customization available on request.
