▌ Product Description
The Meatech MT-VMT-H hydraulic vacuum meat tumbler delivers the same vacuum marination performance as the standard MT-VMT GR series — compressing 24–48 hour soaking to a 2–4 hour in-line cycle at -0.085 to -0.09 MPa vacuum — with one critical engineering addition: a powered hydraulic lift system that raises the drum opening to a fixed convenient loading height (typically 800–1,000 mm from floor level) for product loading, then lowers the drum back to operating position automatically. This eliminates the permanent loading platform or forklift manoeuvring that large-drum tumbler installation otherwise requires when drum capacity reaches 1,000L and above.
The GYY hydraulic series covers four drum sizes from 500 kg/batch (MT-VMT-500H, ~1,000L) to 2,000 kg/batch (MT-VMT-2000H, ~3,600L) — the capacity range where drum loading height on a standard fixed-installation tumbler reaches 1.5 m to 2.2 m, making floor-level loading impractical without infrastructure investment. The minimum building height requirement (2,200 mm to 3,200 mm depending on model) determines the installation feasibility: the drum must have full elevation clearance above the operating position. This building height requirement is the primary installation specification to verify before selecting the hydraulic model.
Drum rotation speed on all four GYY models is variable-frequency controlled (2–12 rpm range) — independently adjustable from the product loading and the drum drive, so the hydraulic and rotation systems operate independently. Vacuum specification reaches 0 to -0.085 MPa (MT-VMT-1000H, MT-VMT-1500H, MT-VMT-2000H) and 0 to -0.09 MPa (MT-VMT-500H) — a deeper vacuum ceiling than the standard GR series, enabling more aggressive vacuum-assisted marinade penetration on dense muscle tissue such as whole pork shoulders, beef topside, and bone-in legs where maximum marinade penetration depth is required.

▌ Hydraulic Lift vs Standard Fixed Installation — Key Differences
Comparison Point | MT-VMT-H Hydraulic (GYY) | MT-VMT Standard (GR) |
Drum loading height at 1,000L+ | Hydraulic lift raises drum to convenient height (~800mm from floor) — no platform needed | Fixed installation — drum opening at 1.5–2.2m from floor; forklift or raised platform required |
Building height requirement | Yes — minimum 2,200–3,200mm depending on model (must verify before ordering) | No special ceiling height required — drum height is fixed and lower |
Loading method | Manual, conveyor, or skip hoist at convenient floor height after drum elevation | Forklift, overhead conveyor, or raised loading platform (for drums 1,000L+) |
Vacuum performance | 0 to -0.09 MPa (GYY-1000) / -0.085 MPa (larger models) — slightly deeper ceiling | 0.06–0.08 MPa — standard specification for most applications |
Speed control | VFD standard across all 4 models | Fixed speed (small models) / VFD (MT-VMT-500 and above) |
Best for | Large-drum operations (500–2,000 kg/batch) where loading platform installation is impractical or cost-prohibitive | Operations from 100 kg to 2,000 kg/batch with standard loading infrastructure or smaller drums (100–300kg) where loading height is not a constraint |
Drum capacity range | 500–2,000 kg/batch (4 models) | 100–2,000 kg/batch (9 models — broader range) |
Price point | Higher (hydraulic system adds cost) | Lower at equivalent capacity |
▌Solution Applications — Line Position
Meatech Solution | Role of MT-VMT-H in Line |
Marinated Meat Ready-to-Cook (high volume) | MT-VMT-1000H or MT-VMT-1500H for operations processing 1,000–1,500 kg per marination batch — where the drum size at this capacity would require a 1.8–2.2m loading height in standard configuration. The hydraulic lift allows this capacity to be achieved without a permanent loading platform, maintaining factory floor flexibility. |
Smoked & Cooked Meat Line (industrial scale) | Large-batch ham and bacon curing tumbling (4–8 hours per cycle). MT-VMT-1500H and MT-VMT-2000H are the appropriate models for industrial smokehouse operations where curing batch sizes of 1,500–2,000 kg are matched to a large smokehouse chamber loading capacity. The hydraulic lift is essential for consistent, safe loading of large cured meat batches without a permanent overhead loading system. |
Whole muscle large-format marinating | Whole pork shoulders (5–10 kg each), beef topside, lamb legs, and other large whole-muscle formats require deep marinade penetration that benefits from the deeper vacuum ceiling (-0.09 MPa on MT-VMT-500H) of the GYY series. The hydraulic series is the preferred choice for premium whole-muscle marinated meat product lines supplying hotel kitchens and premium food-service. |
Kebab & Shawarma Line (high volume) | MT-VMT-500H or MT-VMT-1000H for high-volume kebab operations where large batches of bone-in lamb or chicken thighs are marinated in each cycle. At 500–1,000 kg/batch, the GYY hydraulic format provides the capacity without the loading infrastructure requirement of equivalent standard drum sizes. |
▌ FAQ
Q: How does the hydraulic lift mechanism work — is there a risk of drum drop during operation?
A: The hydraulic lift uses a heavy-duty hydraulic cylinder and locking mechanism to elevate the drum for loading. Once the drum is lowered to operating position, it is mechanically locked in place by a positive-locking mechanism that is independent of hydraulic pressure — the drum cannot drop during operation even in the event of a hydraulic pressure loss. The drum is only elevated during the loading and unloading stages; it operates in the lowered, locked position throughout the tumbling cycle. The hydraulic system is controlled from the same PLC touchscreen as the tumbling programme and vacuum system.
Q: What building ceiling height do I need for each model?
A: The minimum building height requirements are: MT-VMT-500H — 2,200 mm; MT-VMT-1000H — 2,475 mm; MT-VMT-1500H — 2,800 mm; MT-VMT-2000H — 3,200 mm. These figures represent the minimum internal clear height required for the drum to reach its full elevated loading position. If your building ceiling height is below these figures, the hydraulic lift cannot reach the full loading elevation — in this case, the standard MT-VMT GR series with a loading ramp or conveyor system is the correct alternative. Always measure and confirm your installation building clear height before specifying the MT-VMT-H model.
Q: Can the tumbling programme be the same as the standard MT-VMT GR series?
A: Yes — the tumbling programme (tumbling time, rest interval, cycle count, rotation speed, vacuum setpoint) is identical between the standard and hydraulic series. The hydraulic lift is an installation engineering feature, not a process engineering difference. The programme parameters used for marinated ready-to-cook meat on the MT-VMT-1000 (standard) can be transferred directly to the MT-VMT-1000H (hydraulic) — same vacuum setpoint, same drum speed, same cycle structure. If you are upgrading from a standard to a hydraulic model at the same capacity, no reformulation of your marination programme is required.
Q: When should I choose MT-VMT-H over MT-VMT (standard) at the same batch capacity?
A: Choose MT-VMT-H when: (1) your required batch capacity is 500 kg or above AND your facility does not have a permanent loading platform, overhead loading conveyor, or forklift access at the drum height; (2) you are operating in a facility where a permanent raised platform would obstruct workflow or violate fire safety egress requirements; (3) your loading team is handling raw meat product batches that make forklift loading at 1.5–2.2m height a safety or hygiene concern. Choose the standard MT-VMT when: your facility already has a loading platform or forklift infrastructure; your required batch capacity is below 500 kg (where drum loading height is manageable); or your building clear height is below the MT-VMT-H minimum requirement.
