YINDA Powder Processing Solution
Freeze Dried Chicken Bone Powder Machine: Fine Grinding Solution (150-200 Mesh)
For producing fine freeze dried chicken bone powder from de-oiled, freeze-dried chicken breast bone, the Yinda YDWF Series Air Classifier Mill (ACM Mill) is a suitable single-stage fine grinding solution.
Quick Answer: What Machine Is Suitable for Grinding Freeze Dried Chicken Bone Powder?
Because the freeze-dried material is already relatively small and brittle after drying and de-oiling, it can be fed directly into the ACM Mill without a separate coarse-crushing stage in most cases.
The recommended process is:
Freeze Dried Chicken Breast Bone (De-oiled) -> YDWF Series ACM Mill -> Cyclone Separation -> Pulse Dust Collection -> Fine Chicken Bone Powder (150-200 Mesh)
In Yinda actual grinding test and according to customer requirements, the YDWF ACM Mill can produce freeze dried chicken bone powder with a fineness of approximately 150 to 200 mesh.
Because chicken bone contains residual fat and protein, the powder may become slightly sticky during high-speed grinding. The YDWF ACM Mill uses air classification instead of screens or sieves, so there is no screen blockage even with slightly tacky material. When temperature control is important for protecting protein quality and reducing fat oxidation, a YDLF series air-cooled chiller can be added.
Confirmed values:
閳?/span> Fine grinding (YDWF ACM): approximately 150-200 mesh freeze dried chicken bone powder

閳?/span> Screen-less design: no blockage from slightly sticky, fatty bone powder
閳?/span> Optional air cooling: YDLF chiller for temperature-sensitive protein/fat protection
The actual production capacity should be confirmed through material testing according to the raw material condition and target fineness.
Introduction
Freeze dried chicken bone powder is a high-protein, high-calcium ingredient increasingly used in pet food, nutritional supplements and functional food products. Freeze drying locks in nutrients and makes the bone brittle, while de-oiling reduces fat content and improves storage stability.
However, turning freeze-dried chicken breast bone into a fine, uniform powder requires a suitable grinding machine. The material contains bone minerals, protein and residual fat, which may cause sticking, heat build-up and inconsistent particle size during grinding. A screen- or sieve-type mill may suffer from blockage, especially when the powder becomes slightly tacky.
The Yinda YDWF Air Classifier Mill (ACM Mill) is designed for this type of fine powder production. With air classification instead of screens, precise particle-size control and optional air cooling, it provides a stable solution for freeze dried chicken bone powder at around 150-200 mesh.
Material Characteristics and Challenges of Freeze Dried Chicken Bone
Freeze dried chicken breast bone is different from ordinary grain or spice materials. Its grinding performance is affected by several characteristics, and each one has a matching solution in the Yinda freeze dried chicken bone powder machine.
1. Brittle After Freeze Drying – Suitable for Direct Fine Grinding
Freeze drying removes moisture at low temperature and makes the bone structure brittle. De-oiled, freeze-dried chicken breast bone is therefore relatively easy to reduce into fine powder, and because the pieces are already small, it can usually be fed directly into the YDWF ACM Mill without a pre-crushing stage.
This simplifies the process and reduces equipment investment compared with hard, large-size raw materials that require two-stage grinding.
2. Residual Fat May Cause Sticking During Grinding
Although the material is de-oiled, a certain amount of residual fat remains in chicken bone. During high-speed fine grinding, friction heat can soften this residual fat, making the powder slightly sticky and prone to adhering to machine surfaces.
In traditional screen- or sieve-type mills, this often leads to screen blockage and unstable output.
Solution: The YDWF ACM Mill uses air classification instead of screens or sieves. There is no screen to block, so the mill can process slightly sticky chicken bone powder with stable, continuous output and uniform fineness.
3. Protein and Fat Are Heat-Sensitive
Chicken bone powder contains protein and fat, both of which are sensitive to heat. Excessive grinding temperature may cause protein denaturation, fat oxidation, off-flavours and reduced powder quality – especially important for pet food and nutritional applications where nutrient retention matters.
Solution: The YDWF ACM Mill works with airflow that helps carry heat away from the grinding zone, and a YDLF series air-cooled chiller can be integrated when stricter temperature control is required, reducing heat accumulation and protecting protein and fat quality during continuous production.
4. Bone Mineral Hardness and Wear
Bone contains mineral components (mainly calcium phosphate / hydroxyapatite) that are harder than pure meat or plant materials. Fine grinding to 150-200 mesh places demands on the grinding components and classification accuracy.
Solution: The YDWF ACM Mill uses high-speed grinding components combined with a dynamic classifier wheel. Oversized hard particles are automatically returned to the grinding zone for further reduction, while only qualified fine powder passes through to collection – ensuring consistent 150-200 mesh output.
5. Final Application Determines Fineness
The required particle size depends on how the chicken bone powder will be used:
閳?/span> pet food and pet supplement formulations;
閳?/span> calcium-fortified food and beverage ingredients;
閳?/span> bone broth powder and seasoning blends;
閳?/span> nutritional powder and functional food applications.
A fineness of 150-200 mesh is commonly required for fine, easy-to-mix chicken bone powder, which the YDWF ACM Mill is designed to achieve.

The complete configuration should be selected according to production capacity, plant layout, cleanliness requirement and final powder specification.
Machine Selection: YDWF Series Air Classifier Mill (ACM Mill)
The Yinda YDWF ACM Mill is an integrated grinding and classification system designed for producing fine and uniform powder without traditional screens or sieves. It combines grinding, air classification and powder separation in one complete system, making it well suited as a freeze dried chicken bone powder machine.
Why Choose the YDWF ACM Mill for Freeze Dried Chicken Bone Powder?
1. Fine Grinding to 150-200 Mesh Without Screens
Unlike traditional grinding equipment that relies on screens for particle-size control, the YDWF ACM Mill uses an air classification system. This avoids screen blockage from slightly sticky, fatty chicken bone powder and provides more stable continuous operation with a more uniform particle-size distribution.
2. Integrated Grinding and Classification
The built-in dynamic classifier continuously separates oversized particles and returns them to the grinding chamber, allowing only qualified 150-200 mesh powder to leave the system. This helps achieve stable powder fineness, improved grinding efficiency and reduced over-grinding.
3. Suitable for Heat-Sensitive Protein and Fat Materials
The ACM Mill adopts airflow classification technology, which helps control the grinding environment. With an optional YDLF air-cooled chiller, it is suitable for processing heat-sensitive materials such as protein- and fat-containing chicken bone powder, helping protect nutrient quality during continuous fine grinding.
4. Wide Application Range
The YDWF ACM Mill is widely used for fine powder processing in industries including food, pet food, pharmaceutical, chemical and nutraceuticals. It can process various dry materials such as freeze dried chicken bone, herbs, grain products, plant-based powders and other dry materials.
YDWF ACM Mill Performance Features
According to different production requirements, the YDWF series provides multiple models with different capacity ranges. Key features include:
閳?/span> Fine grinding and classification in one system
閳?/span> Screen-less powder processing – no blockage from sticky material
閳?/span> Uniform particle-size distribution (150-200 mesh achievable)
閳?/span> Easy disassembly and cleaning
閳?/span> Suitable for continuous production
閳?/span> Efficient dust collection system for cleaner operation
閳?/span> Optional YDLF air-cooled chiller for temperature control
Working Principle
How Does the YDWF ACM Mill Work?
A complete ACM grinding system typically includes a feeding device, ACM grinding chamber, dynamic classifier, cyclone separator, pulse dust collector, induced-draft fan, rotary airlock, control cabinet and powder collection container.
The freeze-dried chicken bone material enters the grinding chamber through the feeding system and is reduced by high-speed rotating grinding components. The airflow then carries the ground powder into the classification chamber.
The classifier wheel separates particles according to size:
閳?/span> particles larger than the required size are returned to the grinding chamber for further grinding;
閳?/span> fine particles that meet the required fineness (150-200 mesh) are transported to the cyclone separator and dust collector for collection.
Through the combination of grinding force, airflow and classification technology, the ACM Mill achieves precise particle-size control and uniform powder output. Because classification is done by airflow rather than a screen, slightly sticky chicken bone powder does not block the system, allowing stable and continuous production.
The cyclone collects most of the powder carried by the airflow. The pulse dust collector captures finer particles that are not separated by the cyclone. The required filter area and airflow should be calculated according to the system design rather than selected only according to the target mesh.
Configuration Options
Option 1: ACM Mill with Complete Cyclone and Pulse Dust Collection
When workshop cleanliness and powder recovery are important, the ACM Mill can be supplied with a complete cyclone separator and pulse dust collector. This configuration captures both coarse and fine fractions, reduces airborne dust and improves powder yield. It is more suitable for food and pet food workshops, continuous production and enclosed production areas.
Option 2: YDWF ACM Mill with YDLF Air-Cooled Chiller
Fine grinding generates heat due to high-speed impact, airflow friction and continuous material circulation. For freeze dried chicken bone powder – which contains heat-sensitive protein and residual fat – a YDLF series air-cooled chiller can be integrated into the system for better temperature management.
Cooling may help reduce the risk of:
閳?/span> excessive heat accumulation;
閳?/span> protein denaturation and nutrient loss;
閳?/span> fat oxidation and off-flavours;
閳?/span> powder sticking caused by softened fat;
閳?/span> reduced flowability;
閳?/span> unstable powder collection.
However, the chiller should not be described as guaranteeing a fixed discharge temperature. The actual powder temperature depends on ambient temperature, material inlet temperature, feeding rate, grinding time, target fineness, equipment model, system airflow and chiller capacity. A required discharge temperature should be treated as a test condition rather than a standard machine specification.
Option 3: SS304 or SS316L Product-Contact Parts
For general food and pet food powder processing, SS304 is commonly considered for product-contact parts. SS316L may be requested when stronger corrosion resistance is required, when the customer has a specific internal material standard, or for pharmaceutical and special food applications. The stainless-steel scope (grinding chamber, feeding hopper, cyclone, powder pipes, collection bin, etc.) should be defined clearly.
Comparison Analysis
Single-Stage ACM Grinding vs. Two-Stage Crushing + Grinding
For small, brittle, de-oiled freeze-dried chicken breast bone, a single-stage YDWF ACM Mill is generally sufficient and more cost-effective. A two-stage process (coarse crusher + ACM Mill) is only needed when the incoming pieces are unusually large or hard. The final decision should depend on feeding size, target fineness, capacity and test results.
Screen-Type Mill vs. Screen-less ACM Mill
Traditional screen or sieve mills often suffer from blockage when grinding fatty, slightly sticky chicken bone powder. The screen-less ACM Mill avoids this problem and provides more uniform particle size and more stable continuous output at 150-200 mesh.
ACM Mill Without Chiller vs. ACM Mill with Chiller
The YDLF chiller is an optional temperature-control configuration. It is not mandatory for every project but is beneficial for continuous production, very fine powder, or when heat-related protein denaturation, fat oxidation and sticking are a concern.
