With the popularity of healthy eating concepts, homemade grain powder and nut butter have become a new trend in home kitchens. However, many users face problems such as jamming, uneven powder quality, and excessive noise when operating grain mills. Based on the ten years of R&D experience of Zhejiang Haruis Factory and combined with users' high-frequency questions, this article provides a scientific, safe, and efficient operation guide to help you easily master the core skills of grain mills. At the same time, through structured data and natural keyword layout, it improves the visibility of articles in Google searches.

1.Equipment knowledge: the core structure and principle of grain mill

Grain mills use high-speed rotating blades or grinding discs to grind dry grains, beans, Chinese medicinal materials and other materials into fine powder. Its core components include:

Motor system: provides power, the power is usually between 300W-1000W, which directly affects the grinding efficiency.

Grinding chamber: made of food-grade stainless steel (such as 304 stainless steel) to ensure pollution-free and wear-resistant.

Blade/grinding disc:

Blunt blade design: suitable for soft grains (such as rice, oats), reducing heat generation and retaining nutrients.

Serrated blade: suitable for hard materials (such as coffee beans, Chinese medicinal materials), more delicate grinding.

Cooling system: air-cooled or liquid-cooled design to prevent overheating during long-term operation.

2. Preparation before operation: Dual guarantee of safety and efficiency

1. Safety checklist

Power supply and grounding: Make sure the socket is well grounded to avoid leakage risk.

Blade fixation: Gently turn the blade by hand to confirm that it is not loose (looseness may cause jamming or splashing).

Grinding chamber cleaning: Wipe the inner wall with a dry cloth to avoid residual materials affecting purity.

2. Material selection and pretreatment

Dryness requirement: The humidity of the material must be less than 15%, otherwise it is easy to agglomerate and clog the blade.

Test method: Crush the material by hand. If it can be easily powdered, it meets the requirements.

Pretreatment skills:

Large chunks of material: such as walnuts and Chinese medicinal materials, need to be crushed to a diameter of ≤2cm.

Shelled materials: such as sesame and flax seeds, no need to be shelled (the shell is rich in fiber, which can increase the nutrition of the powder).

Capacity control:

The filling volume of the grinding chamber should not exceed 2/3 to avoid motor overload.

Example: A 1000ml capacity machine can grind up to 600ml of soybeans at a time.

3. Operation steps: Standardized process from start to completion

1. Standard operation process

Put in materials: Pour the pre-treated dry materials into the grinding chamber and cover with a sealing cover.

Pulse mode: Suitable for hard materials (such as coffee beans), press the "start-pause" cycle, run for 10 seconds each time, and dissipate heat for 5 seconds.

Continuous mode: Suitable for soft materials (such as rice), run continuously for 20-30 seconds.

Start the equipment: Press the start button and observe the uniformity of the powder.

Stop and clean:

After grinding, wait for the blade to stop completely before opening the cover.

Use a brush to clean the blade and grinding chamber to prevent residual materials from oxidizing and deteriorating.

2. Powder adjustment tips

Coarse powder (0.5-1mm):

Applicable scenarios: oatmeal, coarse grain porridge base.

Operation: Shorten the grinding time (10-15 seconds), or select a low speed mode.

Fine powder (0.1-0.3mm):

Applicable scenarios: baking flour.

Operation: Extend the grinding time (30-60 seconds), or repeat grinding 2-3 times.

User search intent solution:

Question 1: How to avoid material splashing during grinding?

Make sure the sealing cover is tightly closed and the material filling amount does not exceed the upper limit of the capacity.

Question 2: What should I do if the motor suddenly stops during grinding?

Immediately turn off the power and check whether it is overheated (touch the motor housing with your hand, if it is hot, cool it down for 30 minutes before using it).

4. Maintenance and care: the key to extending the life of the equipment

1. Daily cleaning

Grinding chamber: Use a dry cloth or a small brush to remove residual powder. It is strictly forbidden to rinse with water (it may cause the motor to short-circuit).

Blade: Wipe with a cotton swab dipped in a small amount of cooking oil to prevent rust.

2. Deep maintenance cycle

Once a month:Check the wear of the blade (if there is a gap or bend, contact the manufacturer for replacement).

Clean the dust from the heat dissipation hole to ensure smooth ventilation.

Once every six months:Contact a professional to lubricate and maintain the motor.

3. Long-term storage recommendations

Disconnect the power supply and place the equipment in a dry, cool place to avoid direct sunlight.

Place a desiccant bag in the grinding chamber to prevent moisture.

Mastering the correct operation method of the grain mill can not only improve the powder purity and nutrient retention rate, but also extend the life of the equipment and reduce the cost of use.
