Product Description

LG-04 Freeze Dryer

Compact and intelligent, the LG-04 is ideal for labs and small-scale production. Features a user-friendly touch screen for precise control over temperature and vacuum. Perfectly preserves fruits, herbs, cosmetics, and biologics, retaining original structure and nutrients. Efficient, reliable, and easy to operate for superior freeze-drying results.

JASTEC Freeze Dryer

JASTEC China Fruit Vacuum Freeze Drying Machine / Fruit Freeze Dryer is an advanced method for the material de-watering.
The vacuum freeze dryer has been very famous for its good results and special capturing water alternatively. It freezes the moisture material in the low temperature and makes the water inside sublimate directly in the vacuum condition. Then it collects the sublimated vapor by means of the condensing way so as to de-water and dry the material. Being processed by the vacuum freeze drying, the physical, chemical and biological states of the material are basically unchanged.The volatile and nutritious contents in the material, which are easy to be denatured in a warm condition, will be lost a little.When the material is freezing dried, it will be formed into a porous one and its volume be basically the same to that before drying. Therefore, the processed material can be recovered quickly if being watered again, because of its large contacting area and it can be stored for a long period in a sealed vessel.

Equipment Operation

Easy 5-Step Operation:

Clean & Slice: Wash fresh ingredients (e.g., strawberries) and cut into pieces.

Load: Arrange flat on trays and insert into the freeze-drying chamber.

Set Program: Use the intelligent touch screen to configure drying parameters.

Run: Start the automated cycle; the system manages temperature and vacuum.

Finish: Once complete, remove dried products for sealed packaging.

Freeze Dryer Applications – Purely Food & Pet Focus

Our freeze drying technology is engineered for premium food preservation and pet nutrition — delivering crisp texture, rich flavor, and long shelf life without additives or heat damage.

Fruits & Vegetables

Meat & Seafood
Lock in freshness of beef, chicken, fish, and shellfish. Ideal for ready-to-eat meals, camping rations, or gourmet ingredients.
Dairy & Fermented Foods
Transform yogurt, cheese, and fermented products into lightweight, shelf-stable powders or crunchy bites — great for baking or on-the-go consumption.
Mushrooms & Herbs
Retain earthy aromas and umami depth in shiitake, truffles, dried chili, and culinary herbs — essential for chefs and food manufacturers.
Pet Treats & Meals
Create 100% natural, grain-free, high-protein treats that dogs and cats love. No preservatives, no fillers — just pure, wholesome nutrition.
— From farm to table, our freeze dryers help you turn fresh ingredients into valuable, storable, market-ready products.

Technical Brief: Lyophilization in Advanced Battery Material Synthesis

1. Li-rich Mn-based Cathode
Challenge: Conventional drying causes cation segregation and particle agglomeration, degrading electrochemical performance.
Lyophilization Role: Rapidly freezes the precursor solution to lock atomic distribution, then sublimates solvent to create a homogeneous, porous morphology.
Outcome: Enhances structural stability, suppresses voltage decay, and maximizes specific capacity (>250 mAh/g).
2. Sodium Iron Sulfate Cathode
Challenge: Thermally sensitive polyanionic structure prone to decomposition and phase transition under high-temperature drying.
Lyophilization Role: Enables low-temperature dehydration, preserving the pristine crystal framework and preventing thermal degradation.
Outcome: Maintains high operating voltage (~3.8V) and improves ionic conductivity via a controlled porous network.
3. Silicon-based Anode
Challenge: Massive volume expansion (>300%) during cycling leads to pulverization and loss of electrical contact in dense structures.
Lyophilization Role: Constructs a robust 3D porous scaffold or "yolk-shell" architecture, providing essential void space for expansion.
Outcome: Accommodates mechanical stress, prevents cracking, and ensures long-term cycle stability.

FAQ

1. How long does a typical freeze-drying cycle take?
 * Fruits/Vegetables: Typically 18–24 hours.
* Other organic materials: Can range from 24 to 48+ hours.
The transparent acrylic drying chamber allows you to visually monitor the drying progress in real-time.

2. Is the LG-04 difficult to operate for beginners?
Not at all. It is designed with a user-friendly interface. The machine offers automatic one-key start modes for standard
processes. A detailed user manual and video tutorials are provided.

3.How do I defrost the cold trap after a cycle?
The LG-04 features an automatic defrosting function. After the drying cycle, you can initiate the defrost mode, which warms the cold trap to melt the ice. The water is then drained easily through the dedicated drainage valve.
4. Does the machine require supervision during operation?
No. The LG-04 is designed for fully automatic operation. Simply load pre-frozen food, select the mode, and start. The machine automatically handles freezing, vacuuming, heating, drying, and finalization.

5. Is daily maintenance complicated?
Maintenance is very simple. After each use, clean any residue from the trays and collection pan, and periodically check the vacuum pump oil sight glass (if applicable). Wipe the exterior with a damp cloth.
