Feather Meal, Blood Meal and Chicken Meal Moisture

Moisture in feather meal, bone meal and other animal feed products plays a crucial role in quality. With varying moisture content in raw materials, on-line NIR measurement is a key tool in ensuring optimum efficiency and quality control. The ability to measure moisture and make instant process adjustments during the production cycle is key.

Chicken Meal

Chicken meal, according to AAFCO, is the dry rendered product from a combination of clean flesh and skin with and without accompanying bone, derived from whole carcasses of chicken thereof, exclusive of feathers, heads, feet and entrails. It is mainly used in pet foods. Chicken meal essentially is taking a roaster and grinding it up, mixing everything together including muscle, skin and bones.

The water content averages around 70%, along with 18% protein and 5% fat. Now take this ground chicken and carefully dry it to a moisture level of 10%. The protein content is now 65% and the fat level is 12%. This product is chicken meal.

Feather Meal

Feather meal is the most important poultry by-product at a rendering plant. The by-products are mostly animal feed, which is produced by rendering (cooking) the waste materials. Feather waste from the poultry processing industry can potentially be used as a protein source in animal feeding operations. Feathers are rich in protein content called keratin and constitute 7-9% weight of the live bird.

They producing a considerable mass which can be converted to valuable meal.  To make FM digestible it must first be converted through a hydrolysis process. Hydrolyzation is completed by cooking the feathers with steam. Hydrolyzed feather contents 40% to 65% moisture. This moisture must be reduced to 8% for improving shelf life as an animal feed.

Blood Meal

Blood meal is hydroscopic and needs to be dried to less than 10-12% moisture and stored in a dry place in order for it not to deteriorate. It is one of the highest non-synthetic sources of nitrogen available. It is a great food supplement for cattle, fish and poultry, and due to its high-lysine content, it is widely used.

Many countries mix it with molasses before using as an animal feed. Blood meal is produced from clean, fresh animal blood, exclusive of all extraneous material such as hair, stomach belching, and urine; except as might occur unavoidably in good manufacturing processes. A large portion of the moisture (water) is removed mechanically by a dewatering process and is then transferred to a rapid drying facility.


Unsurpassed in performance, our sensors can accurately measure  moisture within tenths of a percent of most applications


MoistTech sensors withstand the test of time and are low to zero maintenance


Rely on MoistTech’s NIR moisture sensors to never drift or need re-calibration


A moisture measurement system is essential for the production process and in some cases will pay for itself in less than 30 days

MoistTech is the Best Solution

Ideally, a moisture control system should be able to accurately detect moisture levels at different stages of the manufacturing process, be easy to maintain and tough enough to withstand the harsh, abrasive nature of the raw materials and production environment.

We’ve combined our decades of experience and knowledge with feedback from our industry partners to create a moisture sensor capable of taking instant, non-contact measurements of moisture, temperature, and other vital levels with the utmost accuracy. When it comes to moisture sensors, the IR-3000 is the most advanced system available.


Locate the point in the production process in which measuring moisture will be the most crucial and beneficial. Identify how you will use the moisture measurement data for improvements and if it will tie into your PLC.

Remember this could involve more than one installation point!


A closed loop process is achieved by incorporating a moisture measurement system into the manufacturing process. Developing a proactive solution to moisture control will avoid costly downfalls. 


MoistTech’s experts will assess your specific application with lab tests, calibrations and accuracy results to ensure our equipment will peform for you. All of our sensors are pre-calibrated prior to being shipped to create a plug-and-play operation for the end-user.
