JGJ Industrial Meat Bone Saw Series
Select the worktable, cutting window and blade speed for frozen blocks, ribs, trotters, steaks, poultry and fish. Stainless construction, gas-spring blade tension and motor braking support precise, hygienic production.

Manual-feed industrial band saws
Size the cutting window before choosing motor power
The JGJ series covers small floor-standing and bench-format machines through the much larger JGJ-6000. The critical selection inputs are the maximum product width and height, frozen core temperature, bone density, desired portion thickness, worktable area and handling method. A larger motor does not compensate for a product that cannot be safely supported or guided through the cutting window.
These machines are documented for -18°C frozen meat and large bone-in pieces including ribs, pork, frozen fish, trotters, steaks, chicken and duck. They are manual-feed band saws, distinct from HELPER's four-blade rib saws and automatic-feed systems. Operator exposure, push tools, guarding and task design therefore require careful risk assessment.

Cutting sequence
Stabilize the product before it reaches the blade
Set
Adjust fence, thickness guide, blade guard and table configuration with the machine isolated.
Cut
Use the approved push method and controlled feed rate while keeping hands outside the danger zone.
Measure
Monitor portion thickness, kerf loss, blade condition, temperature and accepted kilograms per hour.
Food-industry construction
Stable blade guidance and cleanable surfaces
- Stainless-steel body with treated flat surfaces.
- IP65-rated execution is claimed for direct high-pressure cleaning.
- Precision-cast stainless drive and auxiliary wheels.
- Industrial gas spring provides floating blade-tension support.
- Tungsten-steel and copper-alloy guide block combines wear resistance and lubrication.
- Direct motor connection with braking function supports rapid stop.
- Door-cover safety switch interrupts unsafe access.
High-pressure cleaning still requires an approved sanitation procedure. Isolate power, remove residues, protect seals and bearings, and confirm chemical concentration and spray direction with the supplier.

Blade and table details vary by size. The official schedule lists model-specific blade lengths and 4T or 3T tooth formats. Machines above the 3500 specification are described with sliding/fixed dual-purpose tables. Confirm blade SKU, table mode and voltage in the quotation.
Yield and cut quality
Manage kerf, drift and surface finish
Cut loss is affected by band thickness, tooth pitch, blade tension, guide alignment, speed, feed pressure and product temperature. A blade that wanders can create variable portions and unnecessary bone dust even when the thickness fence is correctly positioned. HELPER states a guide-amplitude test of 0.01 mm; confirm how that value is measured and maintained.
For trials, weigh incoming blocks, accepted portions, trim, bone dust and remaining ends. Measure portion thickness at multiple points and inspect the cut face for smear, chipping and fracture. Repeat with the coldest and largest production product rather than a convenient soft sample.
Choose the correct architecture
Manual band saw, multi-blade or automatic feed?
JGJ manual band saw
Flexible for changing products and portion requirements where trained operators control each cut.
Four-blade rib saw
For parallel multi-cut processing and a defined rib or bone-in product geometry.
Automatic-feed saw
For repeatable high-volume portions with guarded mechanical presentation to the cutting zone.
Safety and FAT
Test stopping, guarding and real product performance
Stopping time
Measure blade stop after normal stop, emergency stop, door opening and power interruption under defined conditions.
Guard function
Verify door interlock, adjustable blade guard, covers, push tools, fence locking and restart prevention.
Loaded cutting
Run minimum and maximum products at real temperature; record output, thickness, kerf, vibration and blade drift.
Sanitation
Demonstrate safe blade removal, wheel and guide access, scrap collection, drainage and post-clean inspection.
Project information
What HELPER needs to select the model
Send product species, photographs, maximum width and height, frozen core temperature, bone type, required portion thickness, hourly volume and operator method. Include room temperature, floor plan, available voltage, washdown standard, downstream handling and preferred table height. Request the approved general arrangement, electrical diagram, blade list, replacement frequency, safety circuit description, cleaning manual and witnessed FAT protocol. Local machinery regulations and operator risk assessment must be completed before production release.
Buyer questions
JGJ Industrial Bone Saw FAQ
Can the JGJ series cut meat at -18°C?
That is the published application. Performance still depends on product dimensions, bone structure and actual core temperature; validate the coldest production material.
Which model should we choose?
Start with the maximum cutting width and height, then confirm table area, handling method, blade speed and power. Do not select solely from motor rating.
Can the machine be pressure washed?
The exact page states IP65 and direct high-pressure cleaning. Confirm the offered enclosure rating and follow an approved isolation, chemical and spray-direction procedure.
Was an exact operating video verified?
No stable model-specific JGJ operating video was found. The page uses exact official product images and does not substitute an automatic or multi-blade saw video.
