Freeze-Drying Minimum Lots: Small-Lot Ordering and Choosing a Manufacturer

The first snag in placing a freeze-drying OEM order is the wall of the minimum lot. For fruits like strawberry and mango, an order of around 500 kg of fresh raw material is commonly required, which becomes a major hurdle for small-scale D2C or SMEs at the prototype stage. This article organizes the minimum-lot market rates by material, how to choose small-lot-capable contractors who can be consulted from around 10 kg, the relationship between lot and yield, and a staged order strategy from prototype to mass production.

Agriture, centered on Kyotango-produced strawberries, handles small-lot freeze-drying prototyping through a hybrid operation with partner plants. Related article:Popular-material ranking／Processing cost／Commercial freeze-dried strawberries。

Minimum-lot market rates by material

The minimum lot for freeze-drying is determined by the material's moisture content, yield, and equipment operating efficiency. The more a material has high moisture and low yield, the more fresh input is needed to obtain the same finished amount, and as a result the minimum lot tends to grow larger.

Lot and yield list by material (based on raw-material input)

Because the figures vary with the processor, equipment, and quality requirements, the sure way is to convey the conditions (material state, desired finished amount, quality level) at consultation and then obtain a quotation. For fruits and vegetables, the weight in the fresh state is treated as the input; for processed items (tofu, wakame, mochi, etc.), the weight in the pre-dried raw-material state is treated as the input.

Lot circumstances by strawberry form

• Whole: because the yield of shape retention drops, the finished amount tends to be smaller even for the same fresh volume
• Sliced: because chipping occurs in the cutting process, the yield tends to drop even further than for whole
• Diced (cubed): because chipping can be tolerated, the yield is more stable than whole or sliced
• Powder: because it is ground without worrying about chipping or cracking, the yield is less prone to loss

How to find small-lot-capable contractors

Even in the freeze-drying industry, where large lots are common, small-lot-capable contractors exist. Some can be consulted from around 10 kg, and some keep test-drying costs to around 50,000 yen, so at the prototype stage the key is to broaden your options and compare.

Checklist for selecting a contractor

• Flexibility of minimum lot: whether staged ordering, such as prototype from 10 kg and main from 500 kg, is possible
• Quality control system: certifications such as HACCP, ISO, and FSSC 22000, lot management, and traceability
• Raw-material capability: whether they accept brought-in raw material, support raw-material procurement, and cope with seasonality
• Shape range: how far they can handle whole, sliced, diced, and powder
• Major-client track record: mass-production experience with major food manufacturers is a guide to quality control and production stability
• Cost transparency: whether the breakdown of setup, processing, and packaging costs is clearly stated

Agriture's hybrid operation

Agriture holds the raw-material procurement and specification organization of Kyotango-produced strawberries in-house and handles the freeze-drying process in combination with partner plants. The prototype stage runs on the line of small-lot-capable plants, and the decision to switch to mass production is made under the conditions below. It is a setup suited to supporting the launch of D2C companies, SMEs, and subscription brands.

• Processes Agriture holds: raw-material procurement (Kyotango-produced, etc.), specification organization, formulation design, inspection
• Processes partner plants hold: freeze-drying, batch processing, lot management
• Prototype line: carried out at partner plants that handle from 10–50 kg of raw-material input
• Conditions for switching to mass production: approval of prototype quality + confirmation of turnover rate in a market test + agreement on mass-production cost

Staged order strategy from prototype to mass production

Because jumping straight to a 500 kg main order is high-risk, running it in three stages — prototype → limited sale → mass production — is a strategy with few failures. We organize what to confirm at each stage and how to connect it to the next step.

Three-stage order roadmap

Items to nail down at the prototype stage

• Agreement on the material state: put the conditions of variety, origin, sugar content, and ripeness into the specification sheet
• Shape / size: finalize which of whole / sliced / diced / powder
• Packaging and storage: design using aluminum laminate, oxygen absorber, and silica gel together
• Yield track record: record the actual figures at the prototype point and use them for mass-production cost prediction

Securing raw material and adjusting for seasonality

Freeze-drying is fundamentally prepared to match the material's harvest timing. Especially for strongly seasonal materials like strawberry, it is common to process a substantial volume during the in-season period and supply it year-round. The mass-production plan works by counting back from the harvest timing and securing the purchasing route and processing slots in half-year units.

• 3–6 months before the harvest timing: tentatively reserve the purchase of origin, variety, and quantity
• 2–3 months before the harvest timing: secure the processing plant's slot and carry out prototyping
• Harvest timing: main processing, packaging, inspection
• Year-round: inventory design and shipping plan (product lot-number management)

The relationship between cost structure and minimum lot

Freeze-drying cost is composed of four elements: processing cost, raw-material cost, setup cost, and packaging cost. The reason the minimum lot is set large is that, from the standpoint of setup cost and equipment operating efficiency, the structure is such that the smaller the lot, the higher the unit price per kg.

Breakdown of why the unit price rises for small lots

• Setup cost: fixed cost incurred for cleaning and changeover between lots. In small lots it easily loads onto the unit price
• Equipment operating efficiency: for freeze-drying equipment, efficiency is determined by the input per batch
• Raw-material loss: trimmings, cracks, and chips push down the yield, and the larger the mass production, the more relatively it can be absorbed
• Packaging cost: packaging costs such as individual wrapping, aluminum laminate, and oxygen absorber

Cost items to confirm separately at quotation

• Processing cost (per kg): an item whose unit price varies with lot scale
• Setup cost (per batch): the smaller the lot, the greater the impact on the unit price
• Raw-material cost (fresh): for low-yield materials like strawberry, the weight of raw-material loss is large
• Packaging and inspection cost: presence or absence of individual wrapping, oxygen absorber, lot-number printing, and the like

Summary

The minimum lot for freeze-drying varies with the material's moisture content and yield — around 500 kg of fresh for strawberry, 100–300 kg for mushrooms and miso-soup ingredients, and so on. Because some plants accept small-lot prototyping from 10–50 kg, a staged operation of prototype → limited sale → mass production, keeping the initial risk down, is a realistic order strategy.
