SJ-50H Commercial Food Freeze Dryer - 50-70 kg/batch

Model designation: SJ-50H is the primary public model. SJIA-50H may appear in factory records, nameplates, quotations, or earlier technical documents; both refer to the same SJIALAB equipment model.

SJ-50H food freeze dryer overview

The SJ-50H is rated for 50-70 kg/batch of reference fresh material and provides 4.98 m2 of usable tray area. The highest-capacity commercial H model for established small producers that are not yet ready for a 500 kg FFD line.

It is best considered for stable commercial batches and scale-up data generation. Typical applications include fruit, pet food, coffee ingredients, ready-meal components, meat, and seafood trials. The actual fresh load varies with product density, water content, cut size, tray fill depth, and the drying recipe.

Key specifications

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-50H fits in the range

SJ-50H occupies a specific step in the commercial food freeze dryer range. For the nearest capacity choices, compare SJ-35H (35-52 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-50H FAQ

Is 50-70 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-50H 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.
