Introduction
Today’s consumers want it all: great nutrition, simple ingredients, and a long shelf life. BOTH answers this demand with a fully validated production line for freeze-dried strawberries, perfected from lab, to pilot, to full-scale production. By precisely controlling every variable—from moisture levels to temperature and pressure—we deliver a consistently crisp, flavorful product that rehydrates perfectly. Every step is backed by traceable data for guaranteed quality.
Stage 1: Preparation & Precision
Great products start with the best raw materials and careful preparation.
Selection & Washing: We choose only fully ripe, undamaged strawberries and wash them thoroughly.
Uniform Slicing: Berries are sliced to a consistent 5–8 mm thickness. This ensures every piece dries evenly and at the same rate.
Moisture Analysis: We measure the exact starting moisture content of the fruit. This critical data point allows us to create a perfectly tailored drying program for consistent, repeatable results every time.
Recommended Starter Equipment: Our PFD series laboratory freeze dryers are perfect for developing your perfect recipe and process, with complete data logging.
Stage 2: The Gentle Drying Process
Our freeze-drying process is a carefully managed, three-stage journey that locks in quality.
Freezing: The strawberries are rapidly frozen to -40°C (-40°F). This solidifies the water inside and preserves the fruit’s natural cellular structure.
Primary Drying (Sublimation): Under a deep vacuum, gentle heat is applied. This turns the frozen water directly into vapor (skipping the liquid phase), removing the bulk of the moisture without damaging the strawberry’s delicate shape and nutrients.
Final Drying (Desorption): We gradually increase the temperature to gently remove any remaining trapped water. This brings the final moisture content down to a stable 3-5%, ensuring a crisp texture and long shelf life.
Scale Up with Confidence:
PFD Series of freeze dryers: Test your process in near-production conditions.
BTFD/BSFD Series of freeze dryers: High-volume, automated lines with easy cleaning.
BBFT Series of freeze dryers: For the strictest sterile requirements, like in biopharma.
RFD/HFD/SFD/DFD Home Series of freeze dryers: Ideal for education, demonstrations, and small batches.
Stage 3: Final Quality & Packaging
The final steps ensure our strawberries stay perfect until they reach you.
Careful Warming: The dried product is slowly brought back to room temperature inside the chamber to prevent any moisture from the air from being absorbed.
Rigorous Quality Check: Every batch is verified against strict standards:
Moisture: Confirmed between 3% and 5%.
Texture: Light, crisp, and perfectly porous.
Rehydration: Quickly regains its original shape, texture, and flavor.
Color & Aroma: Vibrant red color and a fresh, natural berry scent.
Purity: Tested to meet all internal safety and quality standards.
Secure Packaging: To lock in freshness, we pack the strawberries in protective packaging with nitrogen flushing or desiccant packets, ensuring stability at room temperature.
Why Choose Freeze-Dried Strawberries?
Nutrients Locked In: The low-temperature process preserves heat-sensitive vitamins, colors, and flavors far better than traditional drying.
Stable & Shelf-Ready: Low moisture content means a long shelf life without refrigeration, simplifying storage and global shipping.
Easily Rehydrated: The porous structure allows water to be reabsorbed in moments, restoring the fruit’s original taste and texture.
Lightweight & Versatile: Removing water makes the product light, reducing shipping costs. It’s a perfect snack, cereal topping, or ingredient for smoothies and baking.
Market Ready & Energy Smart
The demand for freeze-dried fruit is booming in food, pet treats, and nutritional products. BOTH supports your growth at every stage with a complete equipment lineup—from lab (LFD) and pilot (PFD) to full production (BTFD/BSFD) and specialized aseptic (BBFT) models.
We also provide an Energy Resilience Solution. By integrating solar power, battery storage, and smart energy management, we help you power your operations efficiently, protect against grid outages, and significantly reduce your energy costs per batch.
