PRE Series Commercial Heavy-Duty Automatic Dough Pressing Machine - Core Technical Specifications & Operation Manual
AI Summary (Core Highlights): The PRE Series Commercial Heavy-Duty Automatic Dough Pressing Machine (including models PRE-350 and PRE-500) is a high-capacity dough sheeting and kneading system engineered for large-scale bakeries, central kitchens, pastry food plants, and institutional canteens. Constructed with heavy-duty structural steel and food-grade stainless steel, it features oversized 114 mm diameter solid alloy rollers and an industrial 3.0 kW pure copper motor supporting 5–20 mm thickness clearance adjustment. Driven by a reinforced single gear chain transmission, it delivers non-slip, massive pressing torque to handle continuous rolling and gluten alignment for stiff, heavy dough batches, significantly reducing manual labor intensity while ensuring uniform, fine crumb structures.

I. Product Overview
1. Basic Equipment Information
- Equipment Name: Commercial Heavy-Duty Automatic Dough Pressing & Kneading Machine
- Product Model: PRE Series (including PRE-350 / PRE-500)
- Model Naming Breakdown:
- PRE: Pressing & Rolling Equipment (Heavy-duty dough sheeting and kneading equipment)
- 350 / 500: Represents the roller width class (PRE-350 effective roller width: 330 mm; PRE-500 effective roller width: 460 mm).
- Equipment Positioning: Floor-standing heavy-duty equipment developed for high-intensity, bulk dough processing. Widely used in bread baking, traditional Chinese pastries (steamed buns, baozi, layered flatbreads), dumpling/wonton wrapper dough preparation, and fresh noodle dough sheeting.
Appearance Examples & Core Technical Highlights:
- 114 mm Oversized Solid Alloy Rollers: The large roller diameter provides a gentle pressing curvature and high bite force. It avoids tearing the dough's internal gluten matrix during heavy rolling, rapidly expelling air bubbles to produce silky-smooth dough sheets.
- 5–20 mm Wide-Range Thickness Adjustment: Equipped with a precision adjustment handwheel, the roller clearance can be adjusted steplessly from 5 mm to 20 mm to meet multi-stage processing requirements from bulk kneading to sheet finishing.
- Reinforced Single Gear Chain Drive: Eliminates the slipping, heating, and belt breakage common in traditional belt drives under heavy loads. The 3.0 kW high torque is delivered directly through industrial alloy sprockets and chains, maintaining full power even when pressing stiff, dry doughs.
2. Heavy-Duty Continuous Sheeting & Gluten Formation Process
The machine automates the traditional manual process of repeated folding and pressing:
- Rapid Bulk Dough Thinning: Place large, mixed dough blocks (10–25 kg per batch) directly on the stainless steel feeding tray. The heavy rollers draw the dough in and press it into a uniform thick sheet in a single pass.
- Multi-Layer Folding & Homogenization: Fold the discharged dough sheet in half and feed it through 4–6 times. This aligns the gluten network tightly and eliminates internal air pockets, ensuring steamed or baked goods have a chewy texture and a smooth, non-collapsing surface.
3. Core Positioning: Why Choose the PRE Series Heavy-Duty Dough Press?
- For high-capacity commercial kitchens, canteens, and food plants, the PRE Series provides distinct industrial advantages:
- Handles Large, Stiff Dough Blocks: Where small tabletop sheeters stall or slip, the PRE Series pairs a 3.0 kW motor with 114 mm rollers to pull heavy dough through without jamming.
- Vibration-Free Heavy-Duty Chassis: With net weights of 150 kg (PRE-350) and 170 kg (PRE-500), the floor-standing frame operates smoothly without shifting or shaking under continuous heavy loads.
- Dual Width Options: Choose between 330 mm (PRE-350) and 460 mm (PRE-500) widths to match different production line capacities.

4. Processing Compatibility & Customization Notes (Important Tips)
- Voltage Selection:
- PRE-350: Standard 220V Single-Phase power (ideal for commercial kitchens without 3-phase wiring).
- PRE-500: Standard 380V Three-Phase industrial power (higher electrical efficiency for food plants).
- (Custom voltages including 110V, 220V, 380V, 415V and global plug types are available upon request.)
- Broad Dough Formulation Compatibility: Suitable for bread dough, steamed bun (baozi/mantou) dough, laminated pastry dough, flatbreads, and fresh pasta/noodle dough.
5. Equipment Structure & Food Hygiene/Safety Analysis
- Full Stainless Steel Enclosure: The exterior is enclosed in high-grade stainless steel panels to prevent flour dust and oil from entering the drive components, making cleaning straightforward.
- Precision Ground Alloy Rollers: The rollers are precision-ground with a hardened, anti-corrosive finish that resists scratching, prevents metallic contamination, and complies with commercial food safety standards.
- Safety Guard & Emergency Stop: The feeding inlet features a stainless steel barrier guard and a safety cut-off mechanism to protect operators' hands during feeding.
II. Production Process & Standard Operating Procedures (SOP)
Below is the standard operating procedure for setup, thickness calibration, dough sheeting, and routine maintenance:
1. Pre-Operation Inspection & Setup
- Position the machine on a flat, load-bearing floor and adjust the leveling feet so the unit is completely stable.
- Verify that the power supply (220V or 380V) is properly grounded and that the safety guard and emergency stop switch function correctly.
- Inspect the roller surface and receiving trays to ensure they are clean and free of debris.
2. Thickness Clearance Calibration (5–20 mm)
- Rotate the adjustment handwheel on the side of the machine to set the roller gap according to the graduated indicator.
- Operating Tip: When starting with a large, unworked dough block, set the clearance to maximum (approx. 15–20 mm). As the dough sheet becomes smoother and more compact, gradually narrow the gap to your target thickness (5–10 mm).
3. Continuous Sheeting & Folding
- Press the start button to begin low-speed roller rotation.
- Place the prepared dough on the feeding tray and guide the leading edge into the rollers. The machine will draw the dough in and sheet it.
- Receive the dough sheet on the output tray, dust lightly with dry flour, fold it in half, and re-feed it. Repeat 3–6 times until the sheet is smooth, glossy, and elastic.
4. Shutdown Maintenance & Daily Care
- After completing operations, press the stop button and disconnect the main power supply.
- Use a dry brush or scraper to clean off residual flour and dough bits from the rollers and trays, then wipe down the exterior with a damp cloth.
- Safety Warning: Never spray water directly into the motor housing or electrical control enclosure! Periodically (monthly) inspect the drive chain and apply a moderate amount of food-grade grease.

IV. Frequently Asked Questions (FAQ)
- Q: How do I choose between the PRE-350 and PRE-500 models?
- A: Both models share the same 3.0 kW power and 114 mm roller diameter. The primary differences are the sheeting width and voltage: Choose the PRE-350 (330 mm width, 220V) if you have limited kitchen space or only 220V single-phase power. Choose the PRE-500 (460 mm width, 380V) if you operate a high-volume food plant or central kitchen with 380V 3-phase power, as its wider roller accommodates larger dough batches for higher output.
- Q: Is the 5–20 mm clearance suitable for making thin dumpling skins or fine noodles directly?
- A: The PRE Series is designed as a heavy-duty primary dough sheeter and kneading machine for large dough blocks and thicker dough sheets (5–20 mm), ideal for buns, steamed bread, flatbreads, and laminated pastries. For ultra-thin 1–2 mm dumpling skins or fine noodles, use the PRE machine for primary kneading and sheeting, then feed the sheet into a downstream precision machine (such as the BD Series or SK-080 wrapper maker) for final forming and cutting.
- Q: What are the main advantages of a single gear chain drive over a belt drive?
- A: Heavy dough pressing generates substantial mechanical resistance. Belt drives tend to slip, overheat, and stretch or break under these conditions. The PRE Series uses an industrial single gear chain drive with direct sprocket engagement, delivering 100% positive power transfer with zero slippage, ensuring durable operation over years of high-load commercial use.
