Specialty food brands
Run planned batches of fruit snacks, candy, herbs, coffee ingredients, and premium prepared foods.
Built for the step between trials and industrial lines
Use commercial H when weekly orders and repeatable production matter, but an FFD cart-based factory line would be premature.
Pet-food producers
Develop and produce premium treats while controlling piece size, fat, sanitation, odor, and moisture-sensitive packaging.
Pilot plants and farms
Generate scale-up data, process seasonal raw material, and validate products before a larger capital project.
Compare 30H, 35H, and 50H commercial models
Choose from the tray area, product water load, site power, and batch frequency rather than the model number alone.
| Model | Usable tray area | Reference fresh load | Best-fit stage | |
|---|---|---|---|---|
| SJ-30H | 2.95 m2 | 30-45 kg/batch | pilot sales, farm processing, and specialty-food production | View Model |
| SJ-35H | 3.5 m2 | 35-52 kg/batch | regular production with several food SKUs | View Model |
| SJ-50H | 4.98 m2 | 50-70 kg/batch | stable commercial batches and scale-up data generation | View Model |
Turn a good recipe into a repeatable production batch
Commercial output depends on standard preparation, loading, cycle records, cleaning, and packaging.
Standardize raw material
Control piece size, pretreatment, fill depth, and tray weight so each cycle starts from comparable conditions.
Measure cycle and labor
Track freezing, drying, unloading, cleaning, packaging, and operator time to calculate useful daily output.
Protect the dry product
Use moisture-barrier packaging, suitable oxygen control, and a dry unloading environment for stable shelf life.
Production questions to settle before purchase
Commercial sizing should connect the machine to the building, people, product flow, and sales target.
Power and room layout
Confirm electrical supply, ventilation, heat rejection, pump placement, drainage, and service clearance.
Batch and daily output
Estimate cycles per week from product thickness, water content, tray loading, and packaging capacity.
Cleaning and changeover
Review food-contact surfaces, tray handling, allergen control, odor, fat, and changeover between SKUs.
Industrial scale-up path
Use commercial H records to size FFD shelf area, condenser load, carts, pre-freezing, and factory utilities.
Commercial food freeze dryer and food lyophilizer models
Compare the SJ-30H, SJ-35H, and SJ-50H machines by tray area, reference fresh load, condenser specification, power and installation footprint.

Commercial food freeze dryer FAQ
What is the difference between 30H, 35H, and 50H?
The main differences are reference fresh load, usable tray area, tray dimensions, condenser specification, machine size, weight, and electrical configuration.
Is 50-70 kg the dry-product output of the SJ-50H?
No. It is a reference fresh-material load. Dry yield depends on the raw product moisture and the selected final moisture.
Can these machines run fruit, pet food, and ready meals?
Yes, but each product needs a separate preparation, tray-loading, drying, sanitation, odor-control, and packaging plan.
When is an FFD industrial line more appropriate?
FFD becomes more appropriate when regular demand, daily raw material, labor, pre-freezing, packaging, utilities, and factory layout support batches of roughly 500 kg or more.
What should I send for a commercial quotation?
Send product photos, piece or layer thickness, fresh kilograms per batch and per day, target moisture, voltage, room size, and expected operating schedule.
Is a commercial food lyophilizer different from a commercial food freeze dryer?
No. The terms describe the same low-temperature vacuum-drying equipment. Food producers usually say freeze dryer, while lyophilizer is common in technical specifications and international RFQs.
How much does a commercial food freeze dryer cost?
Price depends on tray area, refrigeration and condenser duty, vacuum configuration, controls, materials, voltage, shipping, commissioning and documentation. Compare quotations against the same product load and scope.
Planning a 30-70 kg commercial freeze-drying operation?
Send the product, tray load, target batches per week, voltage, room limits, and packaging plan. We will compare the 30H, 35H, and 50H for your workflow.
