Built in full compliance with food hygiene standards and compatible with 110V/220V regional power grids, it excels at grinding soaked soybeans into rich, aromatic soy milk for silken tofu, firm tofu, and tofu skin, while also finely milling rice batter (for Cheung Fun and steamed rice cakes), peanut milk, almond milk, corn juice, and multi-grain beverages—delivering high extraction yields, dry discharged residue, and a silky-smooth texture free of grittiness.

CECLE Commercial Automatic Soy Milk & Tofu Rice Milk Grinder with Automatic Residue Separation

I. Product Overview

1. Basic Equipment Information

  • Product Name: Commercial Soy Milk Soy Products Rice Milk Beating Tofu Grinder
  • Model: DJJ-100 / DJJ-125 / DJJ-130 / DJJ-150
  • Equipment Type: Countertop / Floor-Standing Commercial Continuous Wet Grinder & Automatic Separator
  • Market Positioning: Engineered to resolve common commercial kitchen and artisan workshop pain points—such as time-consuming manual residue filtering, low extraction yields from standard blenders, and residual particulate matter degrading mouthfeel. Widely deployed across commercial breakfast outlets, fresh soy milk specialty stores, traditional tofu and bean curd processing shops, dim sum and rice roll diners, hotel culinary centers, and high-volume commissaries.

Craftsmanship & Engineering Highlights:

  • Dense, Wear-Resistant White Corundum Grinding Stones: Features premium non-toxic, food-grade white corundum abrasive discs. The clearance between the stationary and rotary stones is precisely tuned via a micrometer-threaded adjustment knob, achieving rapid shearing with minimal heat build-up to lock in natural protein activity and soybean aroma.
  • High-Precision Centrifugal Separation with Dual Outlets: Equipped with an internal 100–120 mesh food-grade filtration drum. The high-speed rotational centrifugal force instantly separates the liquid milk from solid dregs, discharging pure soy milk from the front spigot and dried okara (residue) from the rear chute without requiring auxiliary cheesecloth straining.
  • Leak-Proof, Electrically Insulated Sealed Motor Housing: The grinding chamber and motor compartment are isolated by multiple heavy-duty mechanical water seals, preventing liquid ingress and electrical faults while providing optimized heat dissipation for continuous rush-hour operation.

2. Core Working Principle & Functional Modules

The machine operates on the combined principles of hydrodynamic wet shear-milling and centrifugal centrifugal filtration:

  • Synchronized Feeding of Material & Water: Pre-soaked soybeans or soaked rice are fed into the top hopper while the water inlet valve is opened, introducing water and grain in balanced proportions into the milling chamber.
  • Micron-Level Rotary Shearing & Crushing: As the dynamic grinding stone rotates at high speed, the grains are subjected to intense compressive, frictional, and shearing forces within the micro-gap between the stationary and moving stones, grinding the ingredients instantaneously into a fine slurry.
  • Centrifugal Separation & Discharge: The finely ground slurry is flung against the perimeter filter screen by centrifugal force. Pure liquid milk permeates through the screen mesh and pours smoothly from the front milk chute, while coarse okara is intercepted and guided out through the rear residue ejection port—achieving rapid feeding, instantaneous milk extraction, dry residue discharge, and thick, nutrient-dense slurry.
  • Extensive Raw Ingredient Versatility: In addition to yellow and black soybeans for tofu and soy milk production, the machine processes soaked rice (for silky Cheung Fun batter and rice cakes), blanched peanuts, sweet almonds, mung beans, fresh sweet corn kernels, and walnut/nut beverage extractions.

3. Core Value: Why Choose This Equipment?

  • Labor & Time Savings (Eliminates Straining): Traditional milling requires manual squeezing through cloth bags, which is physically demanding and prone to hygiene contamination. This unit automates extraction and separation in one step, freeing valuable kitchen labor.
  • High Extraction Yield & Dry Residue Discharge: Thanks to precision stone clearance calibration and high-speed centrifugal extraction, protein recovery increases by 15%–20%. The discharged okara feels dry, crumbly, and unsticky in hand, preventing ingredient waste.
  • Silky-Smooth Texture Without Grittiness: Slurry filtered through the 100–120 mesh screen feels velvety and smooth on the palate with zero throat catch. Once boiled, the rich milk quickly develops a thick, golden layer of tofu skin on its surface.

II. Production Workflow & Standard Operating Procedure (SOP)

To maintain maximum extraction yield, extend stone longevity, and ensure operator safety, adhere strictly to the following procedures:

1. Raw Material Preparation & Pre-Treatment

  • Soaking Requirements:
  • Dried Soybeans Must Be Fully Hydrated: Soak in room-temperature water for 4–6 hours in summer, or 8–12 hours in winter/cold environments. Hydration standard: The bean surface should be plump and wrinkle-free; beans can be split in half with a fingernail, showing no hard, dry, white core.
  • Rice & Grains: Soak rice for 2–4 hours until grains can be easily crushed between fingertips.
  • Strict Foreign-Object Inspection: Rinse beans thoroughly to remove pebbles, grit, sand, nails, or metal debris! A foreign stone entering the high-speed grinding chamber will chip or crack the corundum discs and jam the motor.
  • Water Flow Balance: Wet grinding requires a continuous water stream; never operate the machine completely dry.

2. Pre-Start Inspection & Stone Clearance Calibration

  1. Place the machine on a level, sturdy work surface and connect it to a properly grounded 110V or 220V power supply.
  2. Step-by-Step Stone Clearance Calibration (Crucial for First Use or Daily Prep):
  3. Before starting the motor, turn the adjustment handle counterclockwise slightly to loosen the gap.
  4. Turn on the power switch to allow the motor to idle.
  5. Slowly rotate the adjustment handle clockwise. The instant you hear a very faint "hissing/whispering" sound of the two stones gently touching, STOP tightening immediately and back it off counterclockwise by 1/2 to 1 full turn (until the contact sound vanishes).
  6. The stones are now locked in the optimal "micro-clearance fine-milling" position. Tighten the locking nut to secure the setting.
  7. Verify that the water supply hose is clamped securely and place collection buckets under the milk spigot and residue chute.

3. Standardized Grinding Operating Guide

  1. With the machine running empty, open the water valve first to allow a gentle stream of clean water to lubricate and rinse the chamber.
  2. Use a scoop to feed the soaked beans into the hopper in an even, steady stream (never dump a full bucket of beans in at once, which will choke the throat).
  3. Monitor the discharge from the milk outlet and residue chute:
  4. If the okara is overly wet or contains unextracted milk: Water flow is too high or the stone gap is too wide; reduce the water flow slightly and turn the handle clockwise a fraction of a turn.
  5. If discharge slows down and the motor sounds strained: Beans are entering too quickly or water flow is insufficient; increase water flow accordingly.
  6. Yield-Boosting Technique (Second-Pass Grinding): Collect the discharged okara from the first pass, mix it with clean water in a bowl to disperse it, and pour it back through the hopper for a second pass to boost overall milk yield by an additional 10%+.
  7. Safety Red Line: Never insert fingers, metal spoons, or rigid sticks into the hopper throat while the machine is running!

4. Post-Shift Cleaning & Preventive Maintenance

  • Online Water Flush: Once all beans are processed, do not turn off the motor immediately! Keep the unit running while flushing water through the hopper for 1–2 minutes to rinse residual slurry and foam from the stones and filter screen, until clean water exits the spigot.
  • Powered-Off Teardown & Deep Cleaning: Switch off the power and unplug the unit. Unlatch the head clamps, lift off the upper cover, and remove the rotary stone and filter ring. Clean away residual bean paste from recesses using warm water and a soft brush or sponge (preventing sour odors and bacterial buildup).
  • Electrical Safety Warning: Wipe down the stainless steel exterior with a damp cloth; never spray high-pressure water hoses directly onto the motor base, power cord, or ventilation slots!
  • Drying & Storage: Allow the opened grinding chamber and stones to air dry completely, then reassemble for the next shift.

IV. Frequently Asked Questions (FAQ)

  • Q: The discharged okara comes out very wet, wasting valuable soy milk. How should I adjust the machine?
  • A: Wet okara is typically caused by two factors: the stone gap is set too wide, or the water flow rate is too heavy. To resolve this: with the motor running, adjust the calibration handle clockwise until you hear a faint stone-rubbing sound, then secure the clearance setting to ensure complete pulverization; simultaneously, reduce the water valve to maintain a steady, moderate stream. Additionally, mixing the first-pass okara with clean water and running it through a second pass will extract virtually all remaining milk.
  • Q: Can this machine grind rice batter for steamed rice rolls (Cheung Fun)? Will the batter turn out coarse or lumpy?
  • A: It is exceptionally well suited for Cantonese steamed rice rolls (Cheung Fun), rice cakes, and artisanal rice noodles. When grinding rice, select the 120 mesh filter screen and thoroughly pre-soak the rice. Adjust the stones to the fine-milling setting to yield an ultra-fine, silky, snow-white batter that steams into translucent, tender, and springy rice rolls without grittiness.
  • Q: What is the operational lifespan of the white corundum grinding stones and filter screen? Are replacements difficult to install?
  • A: When operating with clean, stone-free grains, the wear-resistant white corundum discs typically deliver a commercial service life of 1 to 2 years, while the internal filter screen lasts 6 to 12 months under daily commercial use. Replacement is straightforward: the unit features a modular quick-release clamp assembly. Loosening the head bolts allows operators to replace worn stones or swap filter screens in 3 to 5 minutes without specialized tools.
