QZX250 – 250 kg Commercial Smokehouse Cooking Machine

The QZX250 is a 250 kg per batch, steam-injection smokehouse cooking machine engineered for mid-scale meat-processing facilities, hotel central kitchens, and craft-smoking operations. Delivering the complete four-stage cycle — pre-drying, smoking, steam-cooking, and color development — the QZX250 is the entry point in the QZX steam-injection series. Its compact 1475 × 1140 mm floor footprint allows installation in space-constrained production areas without sacrificing any of the process capabilities available in the larger QZX500 and QZX1000 models.

Steam-Injection Technology Explained

The QZX250 uses dual steam circuits for precise moisture management during the cooking cycle. The high-pressure line (0.3–0.6 MPa) delivers sharp steam bursts that open the meat matrix and promote rapid brine and flavor penetration throughout the product mass. The low-pressure line (≤0.1 MPa) then sustains a gentle, controlled humidity environment during the cooking stage, preventing surface drying and limiting evaporative weight loss. Together, these circuits let operators dial in exact water-activity targets for different protein formats — a level of control that dry-air systems cannot replicate.

Temperature profiling spans ambient to below 100°C for the cooking phase, and below 85°C for the smoke-application phase where lower heat enhances phenol and carbonyl compound deposition on the product surface. The PLC-based controller stores up to 99 independent recipe programs, each defining temperature, steam pressure, smoke density, air-circulation speed, and phase duration independently for every step of the cycle. Pre-loaded templates cover the most common meat types; all parameters are adjustable on the production-floor HMI without factory involvement.

Construction & Hygiene Design

All surfaces that contact product or process air in the QZX250 are fabricated from food-grade SUS304 stainless steel, polished to a hygienic mirror finish. Structural members, trolley frames, and door hardware are all stainless. The single-door design accepts one standard 1030 × 1020 × 1860 mm trolley loaded with hanging hooks or flat wire-mesh trays, giving processors the flexibility to handle whole cuts, stuffed casings, and poultry in the same chamber. The door seal is a food-grade silicone gasket rated for continuous use across the full operating temperature range.

The smoke-generation system mounts externally and feeds conditioned smoke into the chamber through a calibrated inlet. Hardwood chips or sawdust produce consistent, temperature-controlled smoke without open flame or excessive particulate in the product zone. The exhaust outlet connects directly to a facility vent stack, simplifying compliance with local air-quality regulations. Internal corners are fully welded and polished; removable smoke-distribution baffles allow access for deep cleaning between product runs.

Applications & Typical Product Range

The QZX250 is routinely specified for these product categories:

• Whole-muscle meats: hams, pork loins, beef briskets, lamb shoulders
• Emulsified and coarsely ground sausages: frankfurters, bologna, bratwurst
• Poultry: whole birds, bone-in portions, boneless breast pieces
• Cheese and plant-based proteins: smoked mozzarella, tofu, specialty formats
• Seafood: smoked salmon, mackerel, trout, shellfish preparations

At 250 kg loading capacity and two batches per working day, a single QZX250 can deliver 500 kg of finished smoked product per day — sufficient for a retail deli counter, hotel banquet operation, or export pack-house with moderate throughput requirements. Facilities that outgrow the QZX250 can add QZX500 or QZX1000 units to their smokehouse floor without retraining staff or changing trolleys, since all three models use the same 1030 × 1020 × 1860 mm trolley standard. This modular approach to capacity expansion protects the initial capital investment and avoids retooling costs.

PLC Control System & Data Logging

The QZX250 ships with a Siemens or Mitsubishi PLC (specified at order) paired with a 7-inch color touch-screen HMI. The display shows chamber temperature, steam pressure, relative humidity, smoke phase status, and remaining time for the active step in real time. All process parameters are logged continuously to internal storage and can be exported via USB for food-safety traceability documentation under HACCP, BRC, or SQF systems.

The electrical supply requirement is 380 V, 3-phase, 50/60 Hz at 8.6 kW rated draw. A factory-installed main isolator and earth-leakage circuit breaker are standard. The control panel carries an IP54 rating and the power section IP65, protecting both against wash-down water ingress. CE certification covers the complete machine including the control system.

Processing Line Integration

Smokehouse machines sit downstream of the curing and marination stages. For maximum yield and flavor consistency, pairing the QZX250 with an upstream brine injector and vacuum tumbler delivers a continuous, controlled process flow. Brine injection deposits curing solution and seasoning uniformly through the cut at precision depth and pressure. Vacuum tumbling then massages the injected brine to full protein-matrix saturation before the product enters the smokehouse. The resulting moisture retention and smoke-compound bonding are measurably superior to dry-brine or surface-rub methods, particularly in high-throughput operations where batch-to-batch consistency is critical.

Smoke Quality, Wood Selection & Chamber Atmosphere

The flavor and color profile of the finished product are directly determined by the quality and consistency of the smoke delivered to the chamber. The QZX250 smoke generator uses externally sourced hardwood chips or fine sawdust — beech, hickory, cherry, apple, or alder are the most commonly used species — fed through a thermostatically controlled friction or electrical heating element that pyrolyzes the wood material at a controlled temperature without open combustion. This method produces a consistent, predominantly cool smoke rich in phenolic and carbonyl compounds while minimizing polycyclic aromatic hydrocarbon levels to meet EU and equivalent food-safety standards for smoked products.

Smoke density is continuously monitored by an optical sensor in the chamber exhaust duct and fed back to the PLC to maintain the target smoke concentration set in the active recipe program. This closed-loop smoke-density control prevents over-smoking in the early phase — a common cause of bitter, acrid flavor in under-controlled systems — and ensures uniform smoke penetration throughout the 250 kg load from the first hook position to the last. Color-development tracking during the drying and color phases uses time and temperature profiling rather than visual inspection, removing operator subjectivity from the most quality-critical stage of the cycle.

Często zadawane pytania

What fuel source is required for the QZX250?

The QZX250 requires an external steam supply at 0.3–0.6 MPa (high-pressure circuit) and ≤0.1 MPa (low-pressure circuit). The 8.6 kW electrical load powers the fans, control system, and smoke generator. No gas or oil burner is built in; the steam source is typically a facility boiler or standalone steam generator.

How many programs can be stored in the QZX250?

Up to 99 independent recipe programs are stored in on-board memory. Each recipe defines an unlimited number of sequential phases with independent settings for temperature, humidity, smoke, air-circulation speed, and phase duration. Programs are created and edited on the touch-screen HMI without factory involvement.

What trolley size does the QZX250 accept?

The QZX250 accepts one standard 1030 × 1020 × 1860 mm trolley. Both hanging-bar and flat-tray configurations are available. This trolley standard is shared with the QZX500 and QZX1000, simplifying fleet management in multi-unit installations.

What is the typical smoking cycle time?

Cycle time depends on product type and target core temperature. Typical cycles for frankfurters run 90–120 minutes; for whole hams, 4–6 hours. The PLC recipe system automates all phase transitions, requiring no operator intervention once the batch is loaded and the program started.
