SJ-FFD-130 Industrial Food Freeze Dryer - 130 m2, Approx. 1300 kg/batch

Is SJ-FFD-130 the right industrial food freeze dryer for my product and output?

Direct answer: SJ-FFD-130 is best suited to processors whose validated load is above the practical FFD-100 range but does not justify an FFD-150 or FFD-200 line. Its 130 m2 usable shelf area and approximately 1,300 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-130 selection?

FFD-130 sits between more common catalog sizes, so the reason for choosing it should be visible in the production forecast. Use the normal load, seasonal peak and worst-case water load rather than selecting from annual tonnage alone. It can make sense when FFD-100 would require too many weekly cycles but FFD-150 would leave persistent unused area or exceed the preferred utility envelope.

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-130 planning note: Seasonal factories should model both peak-season energy and low-load operation. Partial loading changes heat transfer and may not reduce kWh/kg in direct proportion to product mass.

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: Confirm whether peak-season raw material, frozen storage, carts and packaging labor can feed the extra shelf area consistently.

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-130

Can SJ-FFD-130 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.
