The Custom Batch ZINNTO Freeze-Drying Process

At ZINNTO, we understand that every product is unique, and we're here to ensure your freeze-drying needs are met with precision and care. 

Our personalized consultations provide an opportunity to discuss your specific product, assess its suitability for freeze-drying, and outline the timeline for pickup, delivery, and processing. During the consultation, we'll also provide a detailed cost estimate or timeline on when the estimate will be available, ensuring transparency and satisfaction. 

We begin with a personalized phone or video consultation to understand your goals. Whether you're freeze-drying fruits, vegetables, candy, or specialty items, we’ll walk you through the process, answer questions, and help you prepare your items for drop-off or delivery. 

Once we finalize your order details, we will send out a work order for approval and collect a deposit to reserve your processing slot. This ensures your items are handled promptly and professionally. 

You can drop off your items at our facility or schedule a local pickup. We also accept shipped items from anywhere in the U.S. using secure packaging guidelines we provide. 

This is where the magic happens.

We use Harvest Right freeze-dryers, the industry standard for small-batch and commercial freeze-drying. These machines remove moisture from food through a process called sublimation, which preserves flavor, texture, and nutrients far better than traditional drying methods.

🔬 What Is Freeze-Drying?

Freeze-drying involves three key stages:

1. Freezing – Your food is frozen to temperatures as low as -40°F.
2. Primary Drying (Sublimation) – A vacuum is applied, and heat is gently introduced. Ice turns directly into vapor without passing through the liquid stage.
3. Secondary Drying – Remaining moisture is removed to ensure long-term shelf stability.

This process can take anywhere from 24 to 72 hours, depending on the product type and moisture content.

Once dried, your items are sealed in high-quality mylar bags with optional oxygen absorbers for maximum shelf life. All products are clearly labeled with the information you provide. If you would like to include a list of ingredients or preparation instructions, this can be incorporated into additional labeling.

Your finished product is returned via local courier or shipped nationwide. We’ll notify you when your order is ready and provide tracking if applicable.
