Intelligent Steamer Cabinet | 6–24 Tray Hybrid Steam Source

Product Introduction

Built around a dual-mode steam source architecture, the Intelligent Steamer Cabinet (EBI-DRS Series) is the only HSYL steamer cabinet line that accepts steam from both an external central boiler supply via a DN 20mm Y-shaped inlet and an integrated electric boiler. This hybrid design serves facilities that already operate a central steam plant — hotels with banquet infrastructure, hospital campuses, factory canteens, military mess halls — by letting them tap cheaper facility steam during peak service, while retaining the built-in electric boiler as a standalone option for low-demand periods or for sites without steam infrastructure. Seven models span 6 to 24 trays, with both standard and vertical configurations available at the 12-tray and 24-tray tiers.

Within the HSYL steamer cabinet portfolio, the EBI-DRS Intelligent series sits between the Economic Steamer Cabinet (EBJ-DRS) — an electric-only line covering 4 to 48 trays for budget-focused or max-throughput projects — and the Automatic Steamer Cabinet (EBA-DRS) — a fully automatic 6 to 24 tray line prioritizing labor savings. The Intelligent series differentiates on infrastructure flexibility: buyers who already have (or plan to install) a central steam boiler get the lowest operating cost option in the portfolio, while buyers without steam infrastructure get a future-proof electric unit that can accept external steam whenever the facility upgrades.

Construction is built for continuous commercial duty. The heating element is a SUS304 electric heating pipe with a pure copper vapor cap for corrosion resistance and heat transfer efficiency. The cabinet body uses 3cm overall foaming insulation to minimize standby heat loss and protect operators from burn contact. The door closes against a new multiple-airbag embedded silicone door seal for steam-tight closure, hung on a six-bolt large hinge rated for heavier door loads than standard four-bolt designs. Supporting ribs on both sides of the cabinet prevent chamber deformation under repeated heating and cooling cycles. An AUTOFFILL function with water-shortage power-off protection prevents dry-burn damage if water level drops below safe operating range — a safety feature critical for unsupervised or semi-supervised steaming shifts.

Operation runs through an intelligent control touch screen with timer and temperature controller, allowing free adjustment of cooking duration and steam temperature per menu item rather than fixed preset cycles. Food compatibility covers steamed rice, dim sum (siu mai, har gow, baozi, mantou), seafood (whole fish, shellfish, crustaceans), vegetables (corn, potatoes, leafy greens), and high-temperature steam sterilization of meals and tea sets — making the cabinet a multi-function station rather than a single-purpose steamer. Target venues span mining areas, factories, schools, institutions, troops, hotels, restaurants, and individual commercial operators.

Technical Specification — Full Model Table

The table below lists all 7 models in the Intelligent Steamer Cabinet (EBI-DRS) series with verified technical parameters from the factory specification sheet. Use this table to compare tray count, cabinet dimensions, rated power, voltage, and net weight across the full capacity range.

Note: Dimensions are Width × Depth × Height in millimeters. "Vertical type" denotes a narrower, taller chamber configuration for space-constrained installations. The DRS-6 model carries no rated power figure in the source spec — it operates on control circuitry only when using external steam, with electric boiler power to confirm. Rated Voltage column shows the factory-specified option per model — confirm availability of 220V single-phase option for your target model with HSYL before ordering. Circuit breaker sizing should be coordinated with your electrical contractor based on rated power and local code requirements.

Model Selection Guide by Facility Steam Infrastructure

Daily meal estimates assume mixed menu items (rice + dim sum/proteins + vegetables) distributed across 1–3 steaming cycles per service. When external steam is available, the EBI-DRS uses facility boiler output and drops electrical consumption to control circuitry only. Contact HSYL with your specific steam infrastructure status, menu, and output targets for a precise model recommendation.

Standard Configuration vs Vertical Type — Space Planning Choice

The EBI-DRS series offers two physical configurations at the 12-tray and 24-tray capacity tiers:

• Standard configuration — Wider, lower-profile chamber with a front-opening horizontal door. EBI-DRS-12 measures 695 mm wide × 615 mm deep × 1695 mm high; EBI-DRS-24 measures 1390 mm wide × 615 mm deep × 1695 mm high. This format distributes weight across a wider base and integrates cleanly against a wall or between other cooking equipment at standard counter height. Choose standard when your kitchen has sufficient front-to-back depth and can accommodate the wider footprint.
• Vertical type — Narrower, taller chamber designed for installations where floor width is constrained but ceiling height allows a taller unit. EBI-DRS-12V measures 495 mm wide × 815 mm deep × 1695 mm high (200 mm narrower than standard 12T); EBI-DRS-24V measures 990 mm wide × 815 mm deep × 1695 mm high (400 mm narrower than standard 24T). Both vertical models maintain identical tray count, capacity, and power rating as their standard counterparts. Choose vertical when your equipment zone has limited width — narrow aisles, corner installations, between two pieces of equipment — but sufficient height and depth.

Both configurations share the same 400 × 600 × 50 mm tray size, 4 KG per tray capacity, DN 20mm Y-shaped steam inlet, ≤4kPa water input pressure, ≤0.02MPa vapor pressure, and all 8 confirmed construction features (AUTOFFILL, SUS304 heating pipe, 3cm insulation, airbag door seal, six-bolt hinge, supporting ribs, intelligent touch screen, energy-saving design).

Working Process

The Intelligent Steamer Cabinet operates in two steam-source modes depending on facility infrastructure. Below is the standard operating sequence for both modes:

Mode 1 — External Steam Connection (Facility With Central Steam Plant)

1. Connect external steam supply. Attach the facility steam line to the DN 20mm steam inlet using the Y-shaped connection fitting. Verify inlet steam pressure is regulated to ≤0.02MPa — if facility steam exceeds this rating, install a pressure-reducing valve (PRV) upstream. Connect condensate return line if required by the facility boiler plant design.
2. Establish water supply. Connect the water inlet to a potable water source at ≤4kPa pressure. The AUTOFFILL function manages reservoir water level automatically — when water drops below safe operating level, the system triggers automatic refill; if refill is unavailable, the system cuts power to heating elements to prevent dry-burn damage.
3. Load trays and set intelligent control. Place portioned items onto 400 × 600 × 50 mm trays (max 4 KG per tray) with appropriate spacing for steam circulation. Close the door — the multiple-airbag embedded silicone seal engages for steam-tight closure, and the six-bolt hinge secures the door under repeated cycling. On the intelligent touch screen, set target steam temperature and cooking duration per menu item using the free-adjustment timer and temperature controller.
4. Steam cooking cycle. External steam flows through the DN 20mm inlet and circulates around all trays uniformly at ≤0.02MPa vapor pressure. The 3cm overall foaming insulation minimizes heat loss through the cabinet body during the cycle. The intelligent touch screen displays real-time status. When the programmed cycle completes, an audible and visual alert signals the operator.
5. Unload and reset. Open the door carefully — wait briefly for residual steam to vent. Remove hot trays using oven mitts and transfer to the next workstation, such as a hot-zone cooking station for plating or a packing area for meal assembly. The supporting ribs on both sides of the cabinet maintain chamber geometry across thousands of load/unload cycles.

Mode 2 — Electric Boiler Operation (Stand-Alone Mode)

1. Power up the electric boiler. Connect to the appropriate power supply per model (220V single-phase for DRS-6 through DRS-10; 380V three-phase for DRS-12 and above). The Y-shaped connection method on 380V models ensures balanced 3-phase load distribution — verify with a licensed electrician during installation. Turn the main power switch on.
2. Water fill and AUTOFFILL activation. The AUTOFFILL function fills the boiler reservoir automatically via the ≤4kPa water inlet. The water-shortage power-off protection remains armed throughout operation — if water level drops below the safe heating element threshold, the system immediately cuts power to prevent dry-burn damage to the SUS304 heating pipe.
3. Preheat and steam generation. The SUS304 electric heating pipe with pure copper vapor cap energizes (9kW for DRS-8/10, 12kW for DRS-12/12V, 12kW×2 = 24kW for DRS-24/24V). The boiler generates steam internally and the cabinet reaches operating temperature. Wait for the steam-ready indicator on the intelligent touch screen before loading food.
4. Load, program, cook, unload. Steps 3–5 from Mode 1 apply identically — load trays, set temperature and duration on the intelligent touch screen, run the steam cycle, then unload and transfer to the next workstation.

Hygiene checkpoint: Between services, drain the boiler reservoir (electric mode), wipe the SUS304 interior surfaces with food-safe sanitizer, inspect the multiple-airbag silicone door seal for residue buildup, and verify the DN 20mm Y-shaped steam inlet and condensate drain remain clear of mineral deposits. For external steam mode, the cabinet requires less descaling since facility steam is typically already purified — but the water reservoir and AUTOFFILL sensor should still be cleaned periodically to maintain accurate level detection.

Applications

The Intelligent Steamer Cabinet (EBI-DRS series) serves commercial kitchen formats where hybrid steam source flexibility, intelligent control, and durable construction are valued together:

• Hotel and resort main kitchens. Hotels with central steam plants use external steam mode during banquet service for lowest operating cost, switching to electric boiler mode for low-demand room service periods. EBI-DRS-12 or DRS-24 covers typical hotel restaurant and banquet steaming volume; the intelligent touch screen allows different menu programs for breakfast buffet, banquet service, and à la carte shifts. Suitable for hotels evaluating new food product line projects where steam infrastructure is part of the facility plan.
• School, university, and institutional canteens. High-volume meal service facilities often have central steam infrastructure in the campus utility plant. EBI-DRS-24 or DRS-24V connects directly to facility steam for rice, mantou, and vegetable batch steaming across breakfast, lunch, and dinner services. The AUTOFFILL protection and intelligent timer reduce operator supervision requirements during peak meal rushes.
• Hospital and healthcare dietary departments. Therapeutic diet preparation benefits from precise temperature control via the intelligent touch screen — different diet textures require different steaming temperatures. The SUS304 heating pipe and food-safe construction support hygienic dietary operations, and high-temperature steam sterilization mode sanitizes meal trays and tea sets between patient services.
• Central kitchens and catering factories. Facilities producing 1,000–2,500+ meals per day benefit from external steam connection for lowest cost-per-meal. Multiple EBI-DRS-24 units in parallel connect to the factory boiler plant for continuous output. For cook-chill operations, the cabinet pairs with an automatic tilting steam cooking and cooling machine downstream for continuous processing.
• Mining area and remote facility kitchens. Mining camps, oil field bases, and remote industrial sites often operate centralized utility plants including steam boilers — the EBI-DRS leverages that existing infrastructure rather than requiring dedicated electric boiler capacity for each kitchen station. Durable construction (six-bolt hinge, supporting ribs, 3cm insulation) withstands heavy-use remote-site conditions.
• Military and government mess halls. Standardized steam infrastructure across military and institutional campuses makes external steam connection the natural operating mode. The intelligent touch screen supports standardized menu programs across multiple mess halls, and the AUTOFFILL safety system reduces operator training requirements for rotating kitchen staff.
• Chain restaurants and dim sum houses. Restaurants serving steamed dim sum, seafood, and Cantonese cuisine use EBI-DRS-12 or DRS-12V for à la carte service. The intelligent touch screen stores preset programs for different dim sum items (siu mai, har gow, char siu bau), ensuring consistent quality across shifts and operators.

The highest-value deployment is the hotel and central kitchen scenario with existing steam infrastructure: external steam mode delivers the lowest operating cost per steamed meal in the HSYL portfolio, while the electric boiler backup ensures continuity if the central plant goes down for maintenance.

Advantages

• Dual-mode steam source — infrastructure flexibility. The DN 20mm Y-shaped steam inlet accepts external facility steam at ≤0.02MPa, while the built-in electric boiler (9kW to 24kW) operates standalone when external steam is unavailable. This is the only HSYL steamer series with both options — the Economic Steamer Cabinet (EBJ-DRS) and Automatic Steamer Cabinet (EBA-DRS) are electric-only. Facilities with central steam plants cut steaming electricity cost to near-zero during external steam operation.
• AUTOFFILL anti-dry-burn safety protection. The automatic water fill function maintains reservoir level during operation, and the water-shortage power-off protection immediately cuts heating element power if water drops below safe operating range. This prevents dry-burn damage to the SUS304 heating pipe and reduces fire risk in unsupervised or semi-supervised steaming shifts — a safety feature not universally present on basic commercial steamers.
• SUS304 electric heating pipe with pure copper vapor cap. The SUS304 grade provides corrosion resistance against steam and water contact, extending heating element service life. The pure copper vapor cap maximizes heat transfer efficiency from element to water, reducing steam generation time compared to standard steel-cap designs.
• 3cm overall foaming insulation layer. The full-coverage foaming insulation minimizes standby heat loss through the cabinet body, keeping steam energy inside the chamber and reducing outer surface temperature for operator burn protection. This contributes to the energy-saving operation profile of the EBI-DRS series.
• Multiple-airbag embedded silicone door seal. The door seal uses a new multiple-airbag design embedded in silicone — the airbags compress to fill any minor door alignment gaps, maintaining steam-tight closure throughout the cycle. This prevents steam leakage that would otherwise waste energy and reduce cooking consistency.
• Six-bolt large hinge for heavy-duty door operation. The door hinge uses six bolts rather than the standard four-bolt design found on lighter commercial steamers. This distributes door weight across more mounting points, reducing hinge loosening and door sag over thousands of open-close cycles in high-traffic kitchen environments.
• Dual-side supporting ribs prevent cabinet deformation. Supporting ribs on both sides of the cabinet maintain chamber geometry under repeated heating and cooling cycles. Without this reinforcement, thin-gauge stainless cabinets can warp over time, causing door seal gaps and steam leakage — the EBI-DRS rib design prevents this failure mode.
• Intelligent touch screen with free-adjustment timer and temperature controller. The touch screen interface allows operators to set any combination of steam temperature and cooking duration per menu item, rather than being limited to fixed presets. This supports diverse menus (rice, dim sum, seafood, vegetables, sterilization cycles) from one cabinet without reprogramming overhead.
• Standard and Vertical type options at 12T and 24T tiers. Both 12-tray and 24-tray models offer a standard horizontal-door configuration and a Vertical type alternative with 200–400 mm narrower width. This gives buyers a meaningful choice when the standard footprint does not fit the equipment layout — switch to Vertical type without dropping down to a lower tray count model.
• Multi-function capability including high-temperature steam sterilization. Beyond food steaming, the cabinet supports high-temperature steam sterilization of meals, tea sets, and serving ware — making it a dual-purpose station in kitchens where sanitization capability is valued alongside cooking function.

Power & Electrical Requirements Summary

When operating in external steam mode, electrical power consumption drops to control circuitry only (~50–100W for the intelligent touch screen, AUTOFFILL sensor, and safety interlocks). The rated power figures above apply to electric boiler mode. Circuit breaker sizing and wire selection must be performed by a licensed electrical contractor based on rated power, voltage, local code, and installation conditions. The Y-shaped connection method on 380V models requires balanced 3-phase wiring — verify configuration with the electrician before commissioning.

Food Compatibility and Sterilization Capability

The EBI-DRS series handles a broad food range plus a sanitization function beyond standard steaming:

The sterilization function makes the EBI-DRS a dual-purpose station — useful in hospital dietary departments, hotel banquet operations, and institutional kitchens where sanitization of serving ware between services is part of the workflow.
