SJ-20H Smart food freeze dryer overview
The SJ-20H Smart is rated for 20-30 kg/batch of reference fresh material and provides 2.21 m2 of usable tray area. The largest model in the small H group and a practical bridge between product trials and the 30H commercial platform.
It is best considered for micro-production, farm processing, and commercial readiness testing. Typical applications include premium fruit, candy, pet treats, vegetables, and small ingredient batches. The actual fresh load varies with product density, water content, cut size, tray fill depth, and the drying recipe.

How to interpret the batch capacity
The capacity is a sizing reference, not a guaranteed load for every food. A thin layer of sliced fruit dries differently from a deep tray of puree, cooked rice, meat, or pet food. For reliable model selection, compare usable tray area and water load as well as kilograms per batch.
Where SJ-20H Smart fits in the range
SJ-20H Smart occupies a specific step in the H-series small food freeze dryer range. For the nearest capacity choices, compare SJ-15H Smart (15-22 kg/batch). The series comparison page shows the full capacity progression.
What to confirm before ordering
- Product type, slice or piece thickness, and expected fresh load per cycle
- Required electrical supply and local frequency
- Preferred condenser-temperature configuration and vacuum-pump arrangement
- Available floor space, ventilation, drainage, and cleaning workflow
- Target residual moisture, packaging method, and expected batches per week
SJ-20H Smart FAQ
Is 20-30 kg/batch the finished dry-product weight?
No. It is a reference fresh-material load. Finished weight depends mainly on the starting moisture content and the final moisture target.
Can SJ-20H Smart process different foods?
Yes. The equipment can support multiple food categories, but each product needs its own preparation, tray loading, freezing method, cycle settings, cleaning, and packaging plan.
