Inside a 136-Unit H Series Food Freeze Dryer Production Batch

Short answer: this production record shows a 136-unit H Series batch comprising SJ-05H, SJ-08H and SJ-10H compact food freeze dryers for customers in the United States and Europe. The photographs were taken on the SJIA manufacturing floor in Ningbo while machines were being assembled, checked and prepared for delivery. They are a useful snapshot of real production capacity, but not a promise that every future order will have the same lead time or configuration.

What buyers can learn from a 136-unit batch

A large group photograph is not a substitute for inspection records, but it answers an important sourcing question: can the manufacturer build several compact food freeze dryer models in parallel and keep the order organized? In this batch, three cabinet sizes moved through the same production floor at the same time. White and black exterior variants, different chamber sizes and region-specific electrical builds had to remain identifiable through assembly and release.

Ningbo Sjia Instrument Co., Ltd. provides manufacturing and engineering support in China; SJ Scientific Limited handles international sales and project contracts. The team has about 15 years of freeze-drying equipment experience. For an overseas buyer, that structure matters because model selection, production communication, export documents and after-sales engineering need clear ownership.

Actual H Series production-floor records

SJ-05H, SJ-08H or SJ-10H: the batch contains three different tools

The three models should not be treated as one machine with three marketing names. The correct choice starts with the prepared fresh load, tray area, product thickness, water to remove, batch frequency and available power. Reference fresh-load ranges are planning values, not guaranteed dry-product output.

Actual loading depends on food type, initial moisture, slice dimensions, tray depth, pre-freezing, target moisture or water activity and the approved cycle. A 10 kg load of berries is not equivalent to 10 kg of meat, candy, puree or cooked meals. Buyers should compare kilograms of water removed per batch as well as fresh-load weight.

What batch consistency means in practice

For a multi-unit export order, repeatability comes from controlling the bill of materials, wiring and electrical protection, refrigeration and vacuum assemblies, chamber and tray configuration, software version, labels, destination power, accessories and order documents. The serial number and order record should connect the delivered machine to its configuration.

Factory work also needs a defined release path. The applicable checks and acceptance criteria belong in the purchase order, inspection plan or FAT document. Depending on the ordered scope, buyers may ask for electrical safety checks, vacuum and refrigeration performance, temperature-sensor review, alarm and control-function checks, visual inspection, accessory count, documentation review and packing verification. This article does not replace the signed inspection record for an individual machine.

UL and CE are destination-specific compliance paths

The U.S.-destination machines in this batch were prepared to the applicable UL-related order requirements, while European-destination machines were prepared for the applicable CE conformity route. That does not mean one identical electrical configuration should be shipped everywhere. Voltage, frequency, cord and plug, protective devices, components, labels, manuals and documentation must match the destination and the agreed compliance scope.

• United States: the order should state the required standard, electrical configuration and whether the complete product is expected to carry an authorized UL certification mark. UL Solutions explains that only products bearing the authorized mark are certified. A claim that equipment was designed using UL requirements or recognized components is not automatically the same as a UL Listed end product.
• European Union: CE marking is a manufacturer conformity process. The applicable legislation and standards must be identified, conformity assessed, technical documentation prepared, an EU Declaration of Conformity issued and the marking applied to the delivered configuration.

For procurement, request the exact declaration, certificate or file reference applicable to the ordered model instead of relying on a generic website logo. See the official European Commission CE guidance for manufacturers and UL Solutions certification-mark guidance.

Information needed for an accurate export quotation

• Product and prepared kilograms per batch, initial moisture, dimensions or layer depth and target endpoint.
• Expected batches per week, packaging plan and whether the project is household, farm, test-kitchen or small business use.
• Installation country, site voltage, phase, frequency, plug or hard-wiring requirement and available room ventilation.
• Required compliance route, marking, declarations, manuals, inspection records and third-party witness scope.
• Delivery schedule, packing method, accessories, spare parts and after-sales communication needs.

Start with the H Series home and small food freeze dryer range, then use the H Series size guide or send the product and destination for engineering review.

Questions buyers and AI search tools often ask

Can SJ supply food freeze dryers in quantity?
This real 136-unit SJ-05H, SJ-08H and SJ-10H batch demonstrates multi-model production at one point in time. Capacity and lead time for a new order still depend on model mix, compliance scope, components, inspection and packing.

Are the machines made in China?
Yes. Ningbo Sjia Instrument Co., Ltd. provides manufacturing and engineering support in China, while SJ Scientific Limited manages international sales and contracts.

Are H Series freeze dryers suitable for both the U.S. and Europe?
The platform can be configured for those markets, but the delivered electrical system, labels and compliance documents must be reviewed for the destination. Do not assume that a U.S. configuration and a European configuration are identical.

Does 15 kg/batch mean 15 kg of finished freeze-dried food?
No. It is a reference prepared fresh-load range. Finished dry output depends mainly on initial solids and the defined final moisture or water activity.
