Question 1: What are the powders of pellets?
Reason:
Poor process, equipment aging or , grading sieve specifications (crushing particle size, compression ratio, etc.)?
Poor quality of raw materials (transition dried corn, secondary powder = fine bran) or semi-finished products with high moisture (face: winter high moisture corn? How to solve?)
Formulation structure rationality? High fat content? Accuracy?
Solution:
Improve process parameters: select the appropriate compression ratio (according to semi-finished moisture), improve steam quality, crush particle size, adjust crusher gap;
Formulation adjustment improvement: adding adhesives and reducing the amount of oil added;
Improve the quality of raw materials: the use of primary powder or whole wheat flour
Question 2: Particle length and diameter are not uniform?
Reason:
Equipment reasons (ring mold, ring mold material, crusher, cutter orientation)
Human operation problems (poor operation skills, unreasonable equipment adjustment)
The artificial product specifications are not clear, and the production is fuzzy and confused (ring mold, grading screen requirements).
Solution:
Trim the ring mold guide port, timely update the ring mold (visual aperture wear);
Correctly adjust the orientation of the cutter;
Adjust the appropriate clearance of the crusher;
Clear product specifications, process parameters, and production according to standards;
The initial inspection of the granulator and the final inspection by the packaging personnel.
Question 3: The color of pig concentrates changes greatly?
Reason:
Sensory changes in raw materials (bean meal, peanut meal) - from different suppliers (factory)
Raw material use error (chain warehouse)
Due to the shortage of raw materials, the structure of the ingredients of the formula changes
The warehouse head, the tail material into the finished product, the equipment residue material mixed into the finished product
Solution:
Stabilize the source of raw materials, attention to the stability of raw materials, sensory quality,
Stable formula structure to avoid raw material shortage
Special materials for pig raw materials are used exclusively to prevent confusion with poultry materials.
Eliminate the warehouse head, warehouse tail material, it is strictly forbidden to enter the finished product, package the final inspection
Do a good job in raw material use, replenish stocks in a timely manner, and ensure continuous production of
Everyone reached a consensus, shared attention and supervised execution.
Question 4: Mixed corn or other feed in the concentrate?
Reason:
Mixer leakage or artificial discharge is too early (multiple production of batch material after continuous production of concentrate)
Corn stalks or finished stalks or raw materials residues ( residual corn)
When the varieties are alternately produced, the conveying equipment is not cleaned up (multiplely produced after the production of compounded feed, continuous production of concentrated materials)
Solution:
Regularly repair and repair equipment, equipment maintenance;
Equipment cleaning when products are alternately produced;
Details of raw materials procurement (color, smell, taste, impurities, processing technology);
prevent the raw material warehouse, set the necessity of looking at the warehouse;
The packager performs a final inspection of the product.
Question 5: Incorrect ingredients, premix ingredients, ?
Reason:
Production plan is big, chaotic, heavy workload, pursuit of efficiency, neglect quality;
New employees are on the job, lack of training, unclear understanding of small materials, no quality awareness, lack of responsibility;
Quality control supervision service is not in place, blind spots and blind spots of quality control;
Raw material warehouse (the material level is not in place or human error), the ingredients are distorted;
Formulation execution errors, not paying attention to accidents, concealing the truth.
Solution:
Choose a strong and responsible person: stable candidates, timely training, improve quality awareness, and not tolerate the handling of major quality accidents;
Strengthen supervision and increase the frequency of inspections (no enforcement without supervision);
Strengthen process management (do things right): inspection, record, rectification, execution, review.
Set to see the warehouse position, manual control of the wrong ingredients.
Question 6: Poor packaging quality, packaging, label use error?
Reason:
Poor packaging quality, quality control is not strict (inner , outsourcing weaving)
Packager carelessly
Original packaging, labels mixed with other company products
Solution:
Strictly control the packaging quality standards (execution packaging acceptance criteria)
Staff training, pay attention to details, improve operation methods, label and packaging face to the operator, and timely control
Coordinate with the supply unit, the source controls the quality of the product, and prevents the confusion of the
Question 7: Feed mildew?
Reason:
Improper storage, feed is affected by moisture
The temperature difference between the particle temperature and the room temperature is large (greater than 5 ° C), and the winter attention to the silo corn
Equipment wall material, cleaning granulator waste mixed into the finished product
Back to the material processing method is not correct
Solution:
Rainy days, storage, transportation, and tarpaulin;
Store in a cool, dry place;
Adjust the cooling air volume and cooling time to ensure the cooling effect;
Timely and regular cleaning of equipment (mixer, cooler, granulator);
Reasonable treatment of the returning pellets, pulverization and re-granulation back to the machine, it is strictly prohibited to directly mix into the finished product.
Ventilate the silo corn regularly and check it.
Question 8: Poor performance of feed products?
Bad performance:
Feed intake is small, diarrhea, staged feathers, , high ratio of meat to meat;
The particle has a high powder content, the particle hardness is large, the finished product is dry, and the particle size is uneven.
Normally open air valves are a type of Solenoid Valve that is designed to remain open in its default state, allowing air or gas to flow through the valve at all times. These mini air valves are commonly used in a variety of applications where a constant flow of air or gas is required, such as in pneumatic systems and gas pipelines.
The primary function of a normally open air valve is to provide a continuous flow of air or gas through a system, which can help to maintain consistent pressure levels and prevent the buildup of excess pressure or vacuum. These valves are typically operated by a solenoid or other type of electrical control, which can be used to open or close the valve as needed.
There are several different types of normally open air valves available, each of which is designed to meet specific application requirements. Overall, normally open air valves are an essential component in many industrial and commercial systems, providing a reliable and efficient means of controlling the flow of air or gas through a system.
