1. Preparation before hair removal: Understand the basics

1. Why is hair removal difficult?

The feathers of chickens and ducks are divided into large feathers (flight feathers, tail feathers), medium and small feathers, and down. The hair follicles attached to the skin have different depths. The difficulty of hair removal is closely related to the type of feathers, the age of the poultry, and the handling method after slaughter. For example:

Live poultry state: The hair follicles of freshly slaughtered chickens and ducks are more active, making it harder to pluck the feathers.

Temperature influence: After the skin cools, the hair follicles contract, increasing the difficulty of hair removal.

Duck feather characteristics: Duck feathers often carry grease, making them harder to handle than chicken feathers.

2. The best timing for hair removal

The best effect for hair removal is immediately after slaughter. At this time, the poultry's body temperature is still present, and the hair follicles are relaxed, making it easier for the feathers to detach from the skin. If temporary storage is needed, it is recommended to refrigerate in the refrigerator (0-4°C) for no more than 24 hours to avoid skin hardening.

3. Preparation of tools

Depending on the hair removal method, commonly used tools include:

Basic tools: hot water pot, thermometer, tweezers, gloves.

Auxiliary tools: hair removal machine, hair removal wax, wooden stick or mixer.

Cleaning supplies: bucket, brush, detergent.

II. Practical methods for quick hair removal of chickens and ducks

Here are several common hair removal techniques, from traditional manual methods to modern tools, suitable for different scenarios.

Method 1: Hot water scalding method (manual hair removal)

Applicable scenario: processing a small amount of poultry, for home use.

Steps:

Heat water: Boil water to 60-70°C (60-65°C for chickens, 65-70°C for ducks); too high can burn the skin, too low makes it difficult for the hair follicles to loosen.

Scalding: Grasp the poultry's legs and immerse its entire body in hot water for 1-2 minutes (ducks slightly longer, up to 2.5 minutes). Gently shake to ensure even heating of the feathers.

Test plucking: After removing, test plucking a large feather from the wing; if it comes out easily, the temperature is appropriate; otherwise, adjust the water temperature or extend the soaking time.

Manual plucking: Start plucking from the large feathers, pulling quickly in the direction of hair growth, then process the medium and small feathers and down.

Advantages: Simple and economical, no complex equipment required.

Disadvantages: Time-consuming, small down feathers require additional cleaning.

Method 2: Hair removal machine assisted method

Applicable scenario: medium to small batch processing, commercial or frequent use.

Steps:

Scalding preparation: Same as the hot water method, scald chickens and ducks to 60-70°C for about 1-2 minutes.

Place in hair removal machine: Put the scalded poultry into a household hair removal machine (small drum type), 1-2 at a time, adding an appropriate amount of water (about 1/3 of the volume).

Start the machine: Run for 30-60 seconds, observing the feather shedding situation, avoiding excessive rolling that could damage the skin.

Check and clean: After removing, rinse with clean water, check for residual down, and remove with tweezers or by hand.

Advantages: High efficiency, suitable for batch processing.

Disadvantages: Requires purchasing equipment, higher initial costs.

Recommended equipment: commercially available small hair removal machine (power 300-500W), priced around 500-1000 yuan.

Method 3: Wax removal method (fine hair removal)

Applicable scenario: Pursuing a clean effect, especially for duck feathers.

Steps:

Hot water scalding: Scald at 60-70°C for 1-2 minutes, slightly plucking the large feathers.

Prepare hair removal wax: Heat the hair removal wax (can use beeswax or commercially available poultry hair removal wax) to 50-60°C, until semi-fluid.

Apply wax: Use a brush or wooden stick to evenly apply the wax on the surface of the chicken and duck, especially in areas dense with down (such as the abdomen and wing roots).

Cooling and tearing: Wait for the wax to cool and solidify (about 5-10 minutes), then quickly tear it off, taking the down with it.

Cleaning: Rinse off residual wax with warm water, checking for cleanliness.

Advantages: Especially suitable for removing fine down, resulting in a clean effect.

Disadvantages: More steps involved, higher cost of wax.

Method 4: Freezing hair removal method (special cases)

Applicable scenario: When immediate processing is not possible.

Steps:

Freezing storage: After slaughter, do not scald, directly place in the freezer (-18°C) for storage.

Thawing and scalding: When using, take out and thaw to a semi-soft state, then scald with hot water at 60-70°C for 2-3 minutes.

Hair removal: Operate according to manual or machine methods.

Advantages: Flexible arrangement of processing time.

Disadvantages: Freezing may slightly affect skin elasticity, making hair removal a bit more difficult.

III. Tips to improve efficiency

1. Temperature control techniques

Use a thermometer to accurately measure water temperature, avoiding judgment based on feel.

If no thermometer is available, you can drop a few drops of water on the back of your hand to test; it should feel warm but not burning, indicating the right temperature.

2. Feather grading processing

First pluck the large feathers (such as wings and tail), then process the medium and small feathers, and finally clean the down; step-by-step operation saves effort.

3. Add auxiliary agents

Add a small amount of salt (about 10 grams per liter of water) or white vinegar (20 milliliters per liter of water) to the scalding water to soften the hair follicles and improve hair removal efficiency.

4. Team collaboration

If processing a large quantity, divide the work; one person can scald, one can remove hair, and one can clean, operating in an assembly line style to save time.

IV. Precautions and common questions

1. Precautions

Safety first: Wear gloves while scalding to avoid burns; pay attention to electrical safety when using the hair removal machine.

Hygiene assurance: Clean tools and hands before and after processing to avoid bacterial contamination.

Skin protection: Avoid excessive scalding or machine rolling that could cause skin damage, affecting appearance and storage.

2. Common questions

Q: What to do if duck feathers are harder to pluck than chicken feathers?

A: Possible reasons:

Grease secretion: Ducks have natural grease on their skin and feathers, making the hair follicles adhere strongly.

Insufficient scalding: Water temperature or time is not enough, failing to sufficiently loosen the hair follicles.

Solution steps:

Increase the scalding temperature to 70°C, extend the soaking time to 2.5-3 minutes, ensuring the hair follicles are fully softened.

Add a small amount of detergent (5 milliliters per liter of water) or white vinegar (20 milliliters per liter of water) to the hot water to break down grease.

First manually pluck the large feathers, then use the wax removal method or small hair removal machine to clean the down.

Finally, rinse with warm water to remove residual grease and feathers.

Q: What to do if the skin turns black after hair removal?

A: Possible reasons:

Water temperature too high: Exceeding 75°C can burn the epidermis, causing tissue discoloration.

Scalding too long: Time exceeding 3 minutes can cause the skin to darken.

Oxidation reaction: Exposure to air for too long without timely processing.

Solution steps:

Next time, lower the water temperature to 60-65°C (for chickens) or 65-70°C (for ducks), monitoring with a thermometer.

Shorten the scalding time to 1-2 minutes, and stop immediately after testing the plucking of large feathers.

Immediately rinse with cold water after hair removal to reduce oxidation, and process or refrigerate as soon as possible.
