Recent SJ-05H Alibaba product work showed that a useful buyer page must answer one real application rather than mixing every food keyword. This guide keeps that narrow intent for FreezeCraft readers. It uses the FC-05 / SJ-05H platform as a selection reference and does not claim a microbial kill step, fixed cycle or guaranteed finished yield.
Define the fish before defining the cycle
Record species, whole or cut form, piece dimensions, skin, bone, fat, salt or marinade and incoming temperature. These inputs change freezing behavior, oxidation risk, vapor load and cleaning.
Freeze drying should not be presented as a validated pathogen kill step. Build the trial inside the applicable pet-food safety plan and keep raw and finished handling separated.
Use 5-7 kg as a wet-load reference
The FC-05 class is published around a 5-7 kg-per-batch reference for suitable materials and loading. Verify the number against four tray levels, actual product depth and the frozen water in the selected recipe.
Finished output will be lower than wet input and varies with solids. Record wet and finished mass instead of advertising one conversion factor for all fish products.
Prepare a repeatable tray trial
Keep piece size, kilograms per tray, tray position and pre-freezing method consistent. Confirm that the center of the largest piece is frozen before evacuation.
Use product observations, weight or another justified endpoint method to decide when the run is complete. A dry-looking surface can hide a moist center.
Plan hygiene, oxidation and packaging together
Define tray and chamber cleaning, raw-product utensils, drain handling and changeover. High-fat fish may need additional oxidation and odor-control review.
Package promptly in a validated moisture and oxygen barrier. Shelf-life and microbiological claims require product-specific testing.
Send an RFQ that can be engineered
Provide species, formulation, wet load, piece size, depth per tray, starting moisture where known, target endpoint, batches per week, destination voltage and installation space.
Ask the supplier to confirm exact electrical configuration, trays, controls, accessories, conformity-document scope, inspection and support for the ordered unit.
Frequently asked questions
Does an FC-05 always hold 7 kg of small fish?
No. Five to seven kilograms is a wet-material configuration reference. Piece shape, tray depth, water content and required endpoint determine a suitable load.
Does freeze drying make raw fish pet treats safe?
Do not treat freeze drying alone as a validated kill step. The full sourcing, preparation, pathogen-control, handling and packaging process must meet the applicable food-safety plan.
This page provides general engineering and operating context. The model-specific manual, approved site procedure, technical agreement and product validation take priority.
