Effective poultry chicken feed mill quality control requires comprehensive training for production personnel and systematic procedures throughout the manufacturing process. Quality is produced by every quality-conscious worker on the poultry chicken feed mill factory production line. Once out of the assembly line, product defects are found in "quality control" afterwards, and rework is time-consuming and laborious, and if it leaves the chicken feed mill factory, it will be even more troublesome. Therefore, quality control must run through the entire manufacturing process of poultry chicken feed making plant.
Rongda Machinery has been a professional feed machinery manufacturer since 2005, with over 18 years of experience in designing and manufacturing feed processing equipment. Our products include feed pellet mills, hammer mills, mixers, coolers, and complete feed production lines, all certified with CE, GOST, and ISO9001 quality management systems.
Hygienic Requirements and Cross-Contamination Prevention
The poultry chicken processing technology must meet strict hygienic requirements to prevent cross-contamination. The main measures taken include:
Equipment Design: Conveyor, silo, chicken feed mixer and other chicken feed making equipment have reasonable structure, smooth surface and no dead corners to reduce the residue of materials. Our ribbon mixers and dual-shaft high-efficiency mixers are designed with smooth surfaces and minimal material retention.
Raw Material Management: The general poultry chicken feed making raw material warehouse should be fixed as far as possible. If there is any change, the poultry feed raw material warehouse should be thoroughly cleaned to avoid pollution caused by the mixing of the two raw materials for chicken.
Regular Cleaning Schedule: Clean up the remaining materials in the batching warehouse, mixer, finished product warehouse, and bucket elevator frame, generally once every 3 days from June to September, and once every 7 days in other months.
Pellet Production Cleaning: When producing poultry chicken pellet feed, the pre-pelletizing bin, poultry chicken feed pellet making machine, and chicken pellet cooler must be thoroughly cleaned for different varieties before granulating, so as to prevent the previous batch of products from polluting the products to be produced. Our pendulum cooling machines and SKLN series cooling machines are designed for easy cleaning between batches.
Drug-Added Feed Production: When producing drug-added feed, the remaining materials in the batching bin, mixer for mixing chicken feed, finished product bin, and conveyor should be cleaned up. When cleaning, 100kg of cleaning material (usually neutral raw materials such as jade powder) can be used to clean the bin for cleaning up drug residues. Especially for the production of chicken poultry feeds, concentrated chicken feeds and chicken premixes with high drug content, each batch should be cleaned to prevent cross-contamination.
Quality Control Before Production
Raw Material Quality Control: The quality and stability of poultry feed raw materials are directly related to the quality of feed products. Therefore, the quality control of raw materials is strengthened to prevent unqualified raw materials, mildew, and pollution. Reliable purchase channels are more important than specific inspections. In particular, many raw materials cannot be fully inspected or are difficult to inspect. Such as: trace element content in zeolite powder, ammonia absorption value, whether calcium hydrogen phosphate is doped with tricalcium phosphate, etc.
Raw Material Selection: Appropriate animal feed raw materials should be selected according to the actual situation. In addition to considering the shelf life of the raw materials, the production time and the compatibility of various chicken feed raw materials (for example, basic copper chloride is more beneficial to vitamins than copper sulfate pentahydrate). Stability and preservation), but also consider the characteristics of some raw materials and other factors. For example, peanut meal is prone to breed Aspergillus flavus in summer, alcohol grains are often not fresh, and corn gluten meal and fish meal are often adulterated.
Raw Material Inspection: All raw materials should be strictly sampled and checked before use. If they are found to have high moisture, moldy, odor, insects, and blending (such as feather meal with fish meal, fermented soybean meal with other non-soybean meal protein raw materials, common plant-derived proteins such as corn gluten, rice protein, cotton meal, rapeseed meal and peanut meal, or meat and bone meal, amino acid bacterial protein, hydrolyzed feather meal, hydrolyzed leather meal, and poor-quality peptone to increase the protein content) shall not be used.
Material Management: A dedicated person should be responsible for the raw materials from the warehouse to the unloading point to ensure that the issued materials are consistent with the formula. At the same time, they should comply with the order of use of the raw materials (including additives or premixes) to ensure the best use effect and the shortest storage period of each poultry chicken feed making raw material.
Equipment Inspection and Maintenance
Daily Equipment Check: Every day after the feed equipment starts to run for 10-15 minutes, the processing equipment must be repeatedly checked and cleaned, including magnetic separation devices, feeders, pulverizers, batching scales, oil injection devices, mixers, granulators and balers (Scale) and so on. Especially for the batching scale, which is the core of the batching process, the accuracy of the electronic scale needs to be checked regularly, but because of its cumbersome calibration and a microcomputer to display its working process, it is easy to be ignored in chicken feed production.
Grinding Machine Inspection: Before processing, check the screen for leaks, leaks, misalignment, etc., and check whether the metal impurities on the magnetic plate above the feeder are cleaned to prevent it from falling into the corn grinder crusher for chicken feed. Our water-drop type hammer mills and wide-chamber hammer mills are designed for easy inspection and maintenance.
Mixing Equipment Inspection: When the poultry chicken feed is mixed, whether the mixer has leakage when the discharge gate of the mixer is closed and whether the material can be completely discharged from the mixer after it is opened. Our single-shaft mixers and dual-shaft mixers are designed for easy inspection and complete discharge.
Equipment Failure Prevention: Equipment failure will bring losses to production. For example, if the magnetic separation device fails, the iron nails in the raw materials will not be removed, and the machine will be damaged, and it will be brought into the feed and endanger the animals. A problem with the accuracy of the batching scale will cause the formula to be distorted, and the packaging machine (scale) will cause the product to exceed the label weight, causing economic loss to the company, or less than the label weight, which will cause the company's reputation loss. It also harms the interests of customers.
Quality Control During Production
The process control of compound chicken poultry feed processing includes both real-time tracking of the raw material status and control of the precision of raw material ingredients. Many of these factors are variable and difficult to control and cannot be ignored. Therefore, every post and chicken feed production process must be reviewed and supervised to form a supervisory responsibility system.
Raw Material Inspection During Processing: The inspection of chicken feed making raw materials in processing refers to when a variety or batch is produced, and the remaining part of the raw materials in the production equipment process is not used up, and it is re-used after a period of inactivity due to a change to other varieties, etc., They must be inspected again (sensory inspection is sufficient), which is more important in summer, especially for crushed corn, corn distillers grain protein feed (DDGS) and other perishable raw materials.
Feeding Process: Pre-feeding inspections are almost all partial inspections. Feeding, as the only comprehensive (sensory) inspection link and final (sensory) inspection of raw materials, must be highly valued. In addition, when changing the feeding variety, you must wait until the previous variety is completely empty before putting into the next variety to avoid cross-contamination.
Raw Material Crushing: The optimum crushing particle size of chicken poultry feed refers to the geometric average particle size that is economically cost-effective and does not affect the animal's health and does not affect the animal's health. It is different due to different animal species, different feeding stages, different composition of raw materials, different tempering and curing methods and forming methods. The animal poultry feed crushing process mainly controls the crushing particle size and its uniformity. In production, the crusher should only be started with no load to avoid excessive starting current and burning of the motor. The material to be fed into the poultry feed hammer mill crusher is required to be uniform to prevent material rushing. Regularly check whether the hammer is worn or not; always pay attention to the crushing capacity of the corn maize hammer mill crusher for chicken fed and the fineness of the material discharged from the animal chicken feed crushing machine.
Ingredients and Mixing: In order to reduce the influence of "air volume" on the accuracy of batching during batching, small diameter (or low speed) batching augers should be used for batching with larger bulk density. In the order of ingredients, large ingredients should be prepared first, followed by small ingredients. When batching, try to consider the symmetrical feeding of the scale hopper, so as not to affect the accuracy of the electronic scale due to excessive unbalanced load. When weighing ingredients manually, especially the ingredients of premix, there must be a correct weighing sequence, and necessary recheck weighing before feeding. In terms of process design and equipment selection, the material entering the batching bin is best conveyed by a rotary distributor, because there will be residues in the auger, and even silo fleeing will occur, which will affect the actual volume of the feed and increase the batching error.
Mixing Process: The mixing time should not be too short, but not too long. If the time is too short, the materials are not fully mixed in the mixer, which will affect the quality of the mixing. If the time is too long, the materials will be over-mixed and cause separation, which also affects the quality. The feeding sequence is usually that the large amount of components are added first or most of them are added to the machine, and then a small amount or a small amount of components are placed on the material. The material with large particle size is added first, and the material with small particle size is added later. Materials with low specific gravity are added first, and materials with high specific gravity are added later. The mixing uniformity of the animal feed mixer for poultry feed should be tested regularly. The coefficient of variation of compound feed and concentrated feed is ≤10%, and the coefficient of variation of premixed material is ≤5% to ensure the mixing quality. Avoid separation using added grease, keep the particle size as consistent as possible, and minimize the loading and unloading of the finished feed after mixing and shorten the transportation distance.
