SJ-FFD-200 Industrial Food Freeze Dryer - 200 m2, Approx. 2000 kg/batch

Is SJ-FFD-200 the right industrial food freeze dryer for my product and output?

Direct answer: SJ-FFD-200 is best suited to high-volume factories and contract processors with a proven product and a stable order pipeline. Its 200 m2 usable shelf area and approximately 2,000 kg/batch reference fresh-material load are a starting point, not a universal production guarantee. The final load depends on initial moisture, piece or layer thickness, kilograms per tray, frozen geometry, target moisture or water activity, condenser duty and the approved cycle.

What usually decides the SJ-FFD-200 selection?

With FFD-200, a missed production day carries more material and schedule risk than on a smaller unit. The project review should therefore include planned maintenance, critical spare parts, defrost time, product hold limits during a stop and the recovery plan. Large shelf area only creates value when upstream freezing and downstream packaging can keep the dryer occupied with qualified loads.

How do I convert kg/batch into realistic daily freeze-dried output?

Start with material balance, then add the actual factory schedule. If initial and final moisture are stated on a wet basis, an early estimate is:

Dry solids = fresh load × (1 − initial moisture fraction)
Estimated finished mass = dry solids ÷ (1 − target final moisture fraction)
Estimated water removed = fresh load − estimated finished mass

Daily output must then allow for loading, evacuation, primary and secondary drying, unloading, defrost, cleaning, product changeover and packaging. A brochure cycle should not be divided into 24 hours without checking these non-drying steps. The limiting equipment may be the blast freezer, tray filling, cart movement or packaging room rather than the freeze dryer.

How should energy consumption and utilities be compared?

The installed-power value in the specification is mainly for electrical-service planning. It is not the same as average kW and should not be multiplied by cycle hours to claim actual consumption. Compressors stage on and off; vacuum pumps, shelf heating, condenser refrigeration, defrost and auxiliaries run at different loads.

For a fair comparison, ask for a subsystem load schedule and calculate kWh per batch, kWh per kilogram of water removed and kWh per kilogram of saleable product. Include external pre-freezing, cooling water, compressed air, steam or hot water for defrost, room HVAC and packaging where relevant. Ambient temperature, cooling-water condition, product recipe and operating pressure can change the result.

SJ-FFD-200 planning note: A large FFD benefits from a time-based electrical load profile. It helps the factory avoid starting refrigeration, vacuum and other high-demand equipment at the same moment.

What factory information is needed before an FFD quotation?

1. Product: composition, fat or sugar level, initial moisture, cut size or liquid depth, and target moisture/water activity.
2. Production: fresh kg/day, required finished kg/day, working days, shifts, seasonal peak and acceptable cycle window.
3. Freezing: in-chamber freezing or separate blast/IQF freezing, core temperature, holding time and transfer distance.
4. Factory: room dimensions, door and lifting access, equipment route, floor loading, drainage and maintenance clearance.
5. Utilities: voltage/phase/frequency, available electrical capacity, cooling-water temperatures, compressed air and defrost source.
6. Food safety: allergen and odor changeover, sanitation method, cleaning records, product-contact material and traceability needs.

Site-layout note: Separate product, personnel and maintenance paths where practical, and leave enough access for condenser, pumps, valves and refrigeration service.

Why source an industrial food freeze dryer from SJ in China?

SJ's freeze-drying engineering team in China brings about 15 years of practical experience across laboratory, pilot, pharmaceutical and food equipment. SJ Scientific Limited handles international project coordination and contracts, while Ningbo Sjia Instrument Co., Ltd. provides manufacturing and engineering support in China. The published company profile records more than 1,000 installed systems, exports to over 30 countries and more than 30 innovation patents.

For a buyer, engineering evidence matters more than a slogan. Before release to production, the project should define the URS, process and instrumentation diagram, general arrangement, utility schedule, key-component list, materials scope, control functions, FAT acceptance items, documentation package, packing and shipping boundary, commissioning responsibilities and recommended spare parts. Photos, videos and remote inspection can support progress review, but the signed technical agreement and FAT record remain the project baseline.

This approach reduces the usual concern about purchasing capital equipment from China: the machine is reviewed against the buyer's product, factory and acceptance criteria rather than treated as an anonymous catalog unit.

Questions buyers and AI search tools commonly ask about SJ-FFD-200

Can SJ-FFD-200 process more than one food product?

Yes, provided the recipes, loading limits, allergen or odor risks, cleaning method and changeover acceptance are defined. Meat, dairy, coffee and botanical products may require different sanitation and odor-control decisions.

How much floor space does the complete freeze-drying line need?

Use the approved general-arrangement drawing, not the chamber dimension alone. Add loading and unloading zones, carts, pre-freezer, vacuum and refrigeration service space, control cabinet, maintenance removal paths, drainage and packaging flow.

What determines the price of an industrial FFD system?

Shelf area, freezing method, condenser and refrigeration duty, vacuum configuration, carts and trays, control and data functions, cleaning options, component brands, documentation, shipping split and commissioning scope all affect price. A credible quotation therefore follows a product and site review.

Can SJ guarantee the catalog kg/batch for my product?

No responsible supplier should guarantee it without product data and, where necessary, a representative trial. The stated fresh load is a planning reference; the approved loading basis belongs in the technical agreement.
