Equipped with intelligent digital temperature instrumentation, anti-dry-burn and anti-overflow probes, and a bottom high-flow sanitary drain valve, it maximizes extraction yields and locks in authentic, rich soybean flavor while eliminating manual pot-stirring and burnt off-flavors—serving as an indispensable powerhouse for commercial production of fresh soy milk, tofu pudding, firm tofu, and silken tofu.

CECLE Industrial and Commercial High-Yield Automatic Soy Milk Grinding and Boiling All-in-One Machine

I. Product Overview

1. Basic Equipment Information

  • Product Name: Industrial and Commercial High-Yield Soybean Milk Machine (Grinding & Boiling All-in-One Unit)
  • Model: SY-40 (Electric Heating / Gas Heating)
  • Equipment Type: Cabinet-Style Commercial Continuous Grinding, Separating & Boiling Integrated Processing Center
  • Market Positioning: Engineered to resolve common commercial kitchen and bean-curd workshop bottlenecks—such as excessive floor space requirements, cumbersome cross-station handling, severe pot-scorching, and inefficient boiling cycles. Widely deployed across chain breakfast franchises, fresh soy milk bars, commercial tofu production workshops, hotel banquet kitchens, supermarket live-food preparation stations, and modern central catering commissaries.

Craftsmanship & Engineering Highlights:

  • Fully Enclosed All-Stainless Steel Cabinet Architecture: The exterior chassis, hopper, transfer pipelines, and boiling vessel are built from thick, food-grade AISI 304 stainless steel with seamless TIG argon-arc welds. Highly resistant to corrosion, acid/alkali exposure, and high-temperature steam, it features brushed and mirror-polished surfaces that fully comply with domestic and international food safety hygiene standards.
  • Closed-Loop Direct Pipeline Transfer: The grinder discharge connects directly to the lower boiling kettle via a sanitary enclosed stainless steel transfer conduit. Freshly extracted raw soy milk flows automatically by gravity into the kettle for immediate heating, eliminating open-air ladle transfers, preventing airborne contamination, and maintaining an exceptionally clean work environment.
  • Dedicated Anti-Scorching Heating Technology (Electric / Gas Options): The boiling kettle utilizes an engineered dual-wall heat-conducting structure paired with multi-directional steam circulation or high-efficiency honeycomb gas burners. Heat is distributed evenly across the curved bottom, completely preventing local hotspots and burnt caramelization, and delivering silky-smooth soy milk with an authentic creamy texture and natural aroma.

2. Core Working Principle & Functional Modules

The machine synchronizes high-speed mechanical centrifugal extraction with advanced thermodynamic boiling:

  • Automated Micron-Level Grinding & Okara Separation: The top-mounted high-speed pure copper motor drives high-hardness precision white corundum grinding wheels. Soybeans and water enter the chamber simultaneously and are pulverized instantly. An internal centrifugal filter screen ejects dry okara (residue) through the lateral chute, while concentrated raw soy milk channels directly into the lower kettle.
  • Rapid Thermal Rise & Deep Homogeneous Boiling: The electric configuration rapidly heats the thermal fluid via high-density heating elements, while the gas model applies uniform high-heat burners to quickly bring the batch to a rolling boil above 100°C. This thoroughly deactivates anti-nutritional compounds (such as trypsin inhibitors and lectins), making the soy milk easily digestible and nutrient-rich.
  • Intelligent Anti-Overflow & Digital Temperature Monitoring: Built-in precision temperature probes and anti-overflow electrodes display milk temperatures in real time via digital readouts. During the critical "pseudo-boil" (frothing) stage, heat can be modulated down to a gentle simmer for 3–5 minutes, ensuring thorough cooking without overflowing the kettle.
  • Bottom-Discharge Sanitary Ball Valve: Once cooking is complete, simply open the heavy-duty stainless steel ball valve at the front of the cabinet. Piping-hot, ready-to-serve soy milk discharges rapidly by gravity into thermal insulated barrels or curdling tubs—eliminating manual lifting or tilting of heavy pots.

3. Core Value: Why Choose This Equipment?

  • Saves Up to 60% Floor Space (Consolidates 4 Machines into 1): Integrates separate grinders, centrifugal separators, boiling stoves, and holding tanks into a single vertical cabinet footprint, streamlining operational flow and optimizing precious kitchen space.
  • Single-Operator Workflow: Grain feeding, residue separation, pipeline transfer, temperature-controlled boiling, and bottom valve discharge are fully interconnected. A single kitchen worker can easily manage hundreds of liters of daily production, substantially lowering labor overhead.
  • Scorch-Free Cooking with Authentic Flavor: Traditional cast-iron cauldrons easily scorch milk at the bottom, creating bitter, burnt off-notes that ruin entire batches. This unit's precision heating curve and curved kettle geometry ensure every batch is sweet, rich, full-bodied, and completely free of burnt flavors.

II. Production Workflow & Standard Operating Procedure (SOP)

To maintain consistent output quality, prolong heating element life, and prevent operator scalding, adhere strictly to the following procedures:

1. Raw Material Preparation & Pre-Treatment

  • Thorough Soybean Hydration: Dry soybeans must be thoroughly cleaned and fully hydrated (soak in room-temperature water for 4–6 hours in summer, or 8–12 hours in winter/cold climates). Soybeans are fully soaked when the surface is smooth and plump, with no hard white core when split in half.
  • Strict Foreign Object Inspection: Inspect and rinse beans to eliminate pebbles, grit, and metal debris. Hard objects entering the high-speed grinding chamber will chip the abrasive wheels or seize the drive motor.
  • Thermal Medium & Utility Verification: For electric models, verify that the heating chamber/jacket water level meets the fill line. For gas models, inspect regulator connections, valves, and gas hoses for tight seals (verify with soapy water for leaks).

2. Pre-Start Inspection & Safety Verification

  1. Ensure the machine rests firmly on level ground with leveling feet locked; verify that the front milk drain ball valve is in the CLOSED position.
  2. Verify that electrical wiring is securely connected and properly grounded (380V 3-phase or 220V single-phase for electric models; gas models require dedicated gas supply and auxiliary control power).
  3. Confirm that the upper grinder locking handle is securely tightened and the grinding clearance knob is set to the neutral clearance position.
  4. Jog the grinding motor empty for 5–10 seconds to verify smooth rotation without abnormal rubbing; test-fire electric elements or gas igniters to confirm proper operation.

3. Standardized Grinding & Boiling Operating Guide

  1. Initiate Water Flow & Feeding: Turn on the grinder power switch, open the water valve to establish a steady, moderate stream, and ladle the soaked soybeans into the top feed hopper at a continuous, steady pace.
  2. Monitor Separation & In-Flow: Dry okara will eject from the side chute, while raw milk drains smoothly through the pipe into the lower kettle. After all beans are ground, continue running water for 1 minute to flush the grinding chamber until the discharge runs clear, then turn off the grinder.
  3. Engage Heating: Close the grinder top cover and the boiling kettle lid. Turn on the electric heating switch (or ignite the gas burner to full heat).
  4. Anti-Overflow & Simmering: Monitor the temperature display. When the temperature reaches 80°C–90°C (the "pseudo-boil" stage, where foam rises rapidly), reduce heat to the simmer setting and simmer continuously for 3–5 minutes to dissipate raw beany off-flavors and ensure thorough protein denaturing.
  5. Discharge Finished Milk: Position an insulated holding container directly beneath the front discharge outlet, slowly rotate the stainless steel handle valve, and dispense the finished soy milk.
  6. Safety Red Line: During heating and discharge, never touch the top steam vent or kettle exterior to prevent scalding! Open the drain valve carefully to prevent hot liquid splashing!

4. Post-Shift Cleaning & Anti-Scorching Maintenance

  • Online Grinder Flush: Immediately after grinding, feed clean water through the hopper while the grinder runs to flush out residual puree, abrasive discs, and mesh filters.
  • Immediate Kettle Rinse (Crucial Anti-Scorching Practice): Clean the boiling kettle immediately after each batch is drained while the metal is still warm! Pour in clean warm water and scrub down the interior walls and bottom using a long-handled soft brush or non-abrasive sponge to remove milk protein film, then open the drain valve to flush completely.
  • Avoid Cold-Shocking Heated Elements: Never dump ice-cold water onto dry-burning heating surfaces immediately after boiling to prevent thermal shock and metal fatigue cracking.
  • Full Shutdown: Turn off the main circuit breaker and shut the gas line supply valve. Wipe down the exterior stainless steel casing with a damp cloth, leaving the kettle lid slightly ajar to air dry.

IV. Frequently Asked Questions (FAQ)

  • Q: How should I choose between the Electric Heating model and the Gas Heating model?
  • A: Both models deliver identical finished soy milk quality, flavor, and extraction rates. The choice depends on your facility's utility infrastructure: If your commercial space is equipped with 380V 3-phase industrial power (or a high-amperage dedicated 220V line), the Electric model is recommended for its flameless, vent-free, clean, and highly precise operation. If you operate in street-front kiosks, open markets, or locations with restricted electric capacity, the Gas model (compatible with LPG tanks or natural gas pipelines) provides powerful, rapid heating at an economical operating cost.
  • Q: Why is it critical to clean the boiling kettle immediately after each batch is drained? Can I wait a few hours?
  • A: It is strongly recommended to wash the kettle immediately after each discharge! Soy milk contains high concentrations of vegetable proteins that quickly bake and harden into a stubborn film when exposed to a hot, empty kettle. If left unwashed, this dried protein layer will carbonize and scorch during the next heating cycle, turning subsequent batches dark and bitter with a burnt off-flavor. Rinsing immediately with warm water and a soft brush takes less than 60 seconds.
  • Q: Can the extracted raw milk be drained directly from the machine for raw chilled packaging or cold tofu processing?
  • A: Yes. The intermediate transfer conduit is versatile. If your production line requires raw soy milk (for traditional artisanal copper-pot curdling or chilled bottled raw milk distribution), simply divert the output conduit into an external collection vessel without engaging the heating system, using the unit as a high-capacity standalone grinder and separator.
