Economic Steamer Cabinet | 4–48 Tray Electric Steamer

Product Introduction

When your central kitchen, restaurant chain, or canteen needs to steam hundreds of portions per service — whether it is rice trays, buns, dim sum, vegetables, or pre-cooked proteins — selecting the right steamer cabinet means matching tray capacity, footprint, and power to your actual daily output rather than guessing or oversizing. The Economic Steamer Cabinet (EBJ-DRS Series) is built around a 14-model capacity ladder ranging from 4 trays to 48 trays, with verified dimensions, electric boiler power ratings, and net weights for every tier. This lets you pick a model that fits your kitchen's floor space and meal volume with confidence instead of relying on generic one-size descriptions.

The series covers three practical size bands: compact cabinets (4–12 trays, 695 mm wide) for smaller kitchens and satellite stations; mid-capacity units (20–30 trays, 1000–1390 mm wide) for restaurant kitchens and medium central kitchens; and high-throughput models (36–48 trays, 1420–1580 mm wide) for large central kitchens and institutional facilities producing thousands of steamed meals per day. For space-constrained layouts where a wide footprint is difficult to accommodate, select models also offer a Vertical type configuration (EBJ-DRS-12V, 24V, 30V, 45V) with a narrower, taller chamber design that fits into tighter floor plans while maintaining the same tray count.

Every model in the EBJ-DRS series uses electric boiler steam generation with configurable voltage — 2~220V single-phase for smaller installations where three-phase power is not available, and 3~380V three-phase for mid and larger models requiring higher power input. The standard tray size across the entire series is 400 × 600 × 50 mm, which is compatible with common commercial kitchen tray systems and GN pan adapters. Each tray is rated for approximately 4 KG of food capacity, giving buyers a straightforward way to convert daily meal portion targets into a minimum tray-count requirement. Steam enters the chamber through a DN 20mm Y-shaped connection at ≤0.02MPa vapor pressure, with water input pressure requirement of ≤4kPa.

For kitchens that are scaling up from individual countertop steamers, replacing aging equipment, or planning a new central kitchen equipment layout, the EBJ-DRS series provides a structured selection path: count your peak-service steamed portions, calculate the tray count needed, check the footprint against your layout drawing, confirm your site voltage, and select the matching model. HSYL supports this process with model-specific specifications and project quotation tailored to your kitchen's conditions.

Technical Specification — Full Model Table

The table below lists all 14 models in the Economic Steamer Cabinet (EBJ-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. 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 the rated power and local code requirements.

Model Selection Guide by Daily Meal Volume

Daily meal estimates assume mixed menu items (rice + buns/proteins + vegetables) distributed across 1–3 steaming cycles per service. Actual tray requirement depends on portion size, menu mix, and cycle frequency. Contact HSYL with your specific menu and output targets for a precise model recommendation.

Standard Configuration vs Vertical Type — When to Choose Which

The EBJ-DRS series offers two physical configurations for select models in the mid-to-large capacity range:

• Standard configuration — Wider, lower-profile chamber with a front-opening horizontal door. Examples: EBJ-DRS-12 (695 mm wide), DRS-24 (1390 mm wide), DRS-30 (1000 mm wide). This format loads at a comfortable standing height and distributes weight across a wider base. 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. Examples: EBJ-DRS-12V (495 mm wide vs 695 mm standard), DRS-24V (1000 mm wide vs 1390 mm standard), DRS-30V (1580 mm wide vs 1000 mm standard), DRS-45V. Note that the vertical type trades width for height — confirm your installation location has adequate overhead clearance for the taller cabinet profile and enough room to open and close the door vertically if applicable.

When planning your kitchen equipment layout, overlay the cabinet footprint (Width × Depth from the spec table) onto your floor plan with at least 300–500 mm of operating clearance on the door side for safe loading and unloading. If the standard configuration does not fit within your allocated equipment zone, check whether a Vertical type alternative exists for your target tray count — this can often resolve space conflicts without dropping to a smaller tray capacity model.

Working Process

The Economic Steamer Cabinet operates as a self-contained electric-batch steaming station. Below is the standard operating sequence for a typical steaming cycle:

1. Loading. Place portioned items onto standard 400 × 600 × 50 mm trays and slide them onto the rack guides inside the chamber. Arrange items so that steam circulation reaches each tray evenly — avoid overcrowding a single tray surface. Close and latch the door to seal the chamber for the cycle.
2. Heating & Steam Generation. The built-in electric boiler (power rating varies by model: 9kW for small units up to 12kW×4 = 48kW for the 48-tray model) heats water to generate saturated steam inside the chamber via the DN 20mm Y-shaped steam inlet connection. Heating time to operating temperature depends on cabinet capacity, initial water temperature, and load mass — larger models with higher total power reach temperature faster relative to their chamber volume. Steam surrounds all trays uniformly, transferring heat to each item through condensation at ≤0.02MPa vapor pressure.
3. Steaming Hold. Once the chamber reaches the target steaming temperature (approximately 100 °C at sea level for standard-pressure operation), the hold phase begins. Duration depends on item type and portion thickness: rice trays may require 20–40 minutes depending on quantity and layer depth, while thin-skinned buns or dim sum may be ready in 8–15 minutes. The operator sets the hold time based on menu requirements using the cabinet control interface (timer type To confirm — mechanical or digital per model).
4. Unloading & Reset. After the timer completes, open the door carefully to allow brief steam venting before reaching in. Remove steamed trays and transfer to the next workstation — such as a cooking range hot zone for finishing plating or a packing area for prepared-meal assembly. Wipe or rinse the chamber and tray racks before the next load. For high-throughput kitchens running multiple cycles per service, a quick-reset protocol keeps downtime between loads short.

Hygiene checkpoint: Between services, drain the boiler reservoir, descale if local water hardness requires it (water input pressure must stay within ≤4kPa spec during operation), and wipe all interior surfaces with a food-safe sanitizer. Regular descaling intervals depend on water quality and daily cycle count — hard-water sites may need more frequent maintenance than soft-water facilities. Ensure the steam inlet Y-connection and any condensate drain lines remain clear of mineral buildup.

Applications

The Economic Steamer Cabinet (EBJ-DRS series) serves commercial kitchen formats where batch electric steaming is a core daily operation:

• Central kitchen. Highest-value application — steaming is often the highest-volume thermal process in a central kitchen producing prepared meals, school lunch components, or airline catering bases. A 30–48 tray cabinet can handle dozens of rice trays or hundreds of bun portions per cycle, making it a throughput-critical station in the overall central kitchen workflow. Large-scale operations may deploy multiple cabinets in parallel for continuous output across breakfast, lunch, and dinner services.
• Restaurant / Hotel kitchen. Hotels with breakfast buffet steaming stations and restaurants serving dim sum, Cantonese cuisine, or health-focused steamed-menu items use cabinet steamers for consistent quality across every service. A 12–24 tray model typically covers the per-service steaming demand of a mid-to-large restaurant kitchen. The cabinet format integrates into a standard equipment lineup alongside ranges and ovens without requiring dedicated steam-room construction.
• Canteen / Institutional kitchen. School, hospital, and corporate canteens serving steamed rice as a staple rely on batch steamers to produce uniform rice portions at scale. An 8–20 tray cabinet matched to the canteen's peak seating capacity eliminates the inconsistency that comes with running multiple small countertop steamers at different temperatures and times.
• Prepared-meal production facility. Facilities producing chilled or frozen meal kits use steamers to partially cook protein and vegetable components before blast chilling or freezing. A 20–30 tray cabinet provides sufficient per-cycle throughput for component cooking lines where controlled moist heat preserves texture better than dry-heat methods.
• Bakery / Dim sum workshop. Production-focused bakery operations and dim sum workshops use cabinet-style steamers for batch proofing or final steaming of products such as steamed buns (baozi), mantou, siu mai, har gow, or rice noodle sheets where steam humidity is essential to product quality. A 12–24 tray model with standard or vertical configuration can fit into production line layouts depending on available floor space.

Advantages

• Full 14-model capacity ladder with verified specs. Unlike generic steamer listings that describe one or two vague size options, the EBJ-DRS series documents every model from 4 trays to 48 trays with factory-confirmed dimensions, power ratings, voltages, and weights. This eliminates guesswork — a buyer can directly map their daily meal volume to a tray count, verify the cabinet footprint against their kitchen layout drawing, and confirm the electrical load requirement before quoting.
• Standard and Vertical type options for flexible space planning. Four models in the series (12, 24, 30, 45 trays) offer both a standard horizontal-door configuration and a Vertical type alternative with a different width-depth-height ratio. This gives buyers a meaningful choice when the standard footprint does not fit neatly into their equipment layout — they can switch to the Vertical type without dropping down to a lower tray count model and losing capacity.
• Electric boiler steam generation — no gas utility dependency. Every model in the EBJ-DRS series uses an integrated electric boiler as its steam source. This simplifies installation by eliminating gas piping, gas safety interlocks, and combustion ventilation requirements. For kitchens where gas access is unavailable, expensive to install, or operationally undesirable, the all-electric design reduces infrastructure complexity and regulatory overhead.
• Scalable power architecture (9kW → 60kW equivalent). The series uses a logical power-scaling pattern: 9kW for compact 4–10 tray units, 12kW for 12 trays, dual 12kW boilers (24kW total) for 20–24 trays, dual 15kW (30kW) or triple 12kW (36kW) for 30–36 trays, and quad 12kW (48kW) for the 48-tray flagship. This progressive scaling ensures that larger chambers receive proportionally higher heating capacity to maintain acceptable heat-up time and steam saturation even at maximum tray loading.
• Uniform tray system across all models. Every model from the 4-tray EBJ-DRS-4 to the 48-tray EBJ-DRS-48 accepts the same 400 × 600 × 50 mm standard commercial tray. This means trays are interchangeable between models within the same facility, spare tray inventory is simplified, and GN pan adapters or custom inserts developed for one model work on any other model in the series.
• Clear capacity metric for planning: 4 KG per tray. The 4 KG per tray capacity rating gives procurement planners and kitchen designers a concrete conversion factor: estimate your peak-service steamed portion weight, divide by 4 KG, add a 15–25% buffer for tray spacing and air circulation, and read the minimum tray count required. This makes the model selection process quantitative rather than subjective.
• Voltage flexibility for global installation. Smaller models (4–12 trays) support both 3~380V three-phase and 2~220V single-phase power, accommodating sites where only single-phase supply is available or where electrical upgrade cost is a constraint. Mid and larger models (20+) are specified for 3~380V three-phase, which aligns with the higher power draw of multi-boiler configurations. Export-market voltage customization should be confirmed with HSYL at quotation stage.
• Cabinet-format ergonomics at standing height. Loading and unloading happen through a front-opening door at standing working height, which reduces operator physical strain compared with bending into low countertop units during high-volume meal prep shifts. For kitchens running multiple steaming cycles per service, the upright cabinet format cuts cumulative bending and reaching time significantly compared with stacking multiple countertop steamers on benchtops.
