For feed enterprises to do a good job in quality management, we must first do a good job in quality control of raw materials. If the quality of raw materials is not effectively controlled, the quality management of feed enterprises cannot be discussed. Therefore, a relatively complete standard system should be formed in the work, and the quality control plan for feed ingredients should be done well.
Standardization, the formation of a relatively complete standard system without rules and rules, the feed enterprises must have such rules in order to do a good job in raw material control, the focus is on sampling standards, raw material standards, testing and testing standards, storage standards. In essence, standards are technical regulations of enterprises, so once they are determined, they cannot be changed at will. In addition, the bidders should be familiar with the standard-setting workflow, and the operators must master the relevant corporate standards.
The first sampling standard is to clearly define the staff of the quality control department. The second is to sample the materials, the solid feed materials are sampled by the diagonal method, and the liquid feed materials are mixed and mixed in the upper, middle and lower layers, and the sampling amount is generally about 1kg. Third, different suppliers and different batches of feed ingredients cannot be mixed and sampled. The fourth is that the sampling method is divided into two parts (one test and one test), and stored in a storage room under dry and dark conditions. The storage period is two months after the product shelf life. Fifth, all samples must be labeled, the main contents include: raw material name, supplier, place of origin, date of purchase, quantity, etc.
Two principles for the development of standards for raw materials for raw materials: respect for science and respect for the actual situation of enterprises. The two principles must be equal, not hard and soft. Too much emphasis on science will increase the quality cost of feed enterprises; too much emphasis on the company's reality, will lose the meaning of quality control, and can not control the quality of raw materials.
Raw material standards must be developed in accordance with industry mandatory standards, such as health standards.
Enterprise formula, industry raw material standards, feed ingredient nutritional value ingredient list or industry standard are the main basis for formulating raw material nutrition index parameters.
According to the specific conditions of the company, the enterprise standards must be stricter than the industry standards.
Acceptance indicator parameters should be clear. Which acceptance indicators cannot be flexible? Which acceptance indicators are flexible and can be conceded? What is the standard for receiving concessions? Who has the power to decide to receive concessions? Be clear.
The feedstock quality control program establishes a qualified supplier system. The procurement channel should not be changed. The feed enterprise should establish a qualified supplier system. By reviewing the supplier's past supply quality record, price, timeliness of supply, strength and other factors, the procurement department and the quality control department jointly submit a list of qualified suppliers, and then submit it to the product manager for approval.
The list of qualified suppliers shall be re-evaluated every year: one failure is met, the supplier is given a verbal warning; the second is unqualified, the supplier is deducted part of the payment; three times is unqualified, and the qualified supplier is disqualified. At the same time, the final elimination method is implemented, and new qualified suppliers are added each year. These measures are used to motivate qualified suppliers to ensure the stability of quality.
The receiving department of the raw material receiving program informs the warehouse management and quality control department in advance that the raw materials will be delivered to the factory and ready for receiving.
The raw materials are weighed by the warehouse tube to verify the consistency with the quantity in the procurement contract. Check whether the original product management department such as the label or the product quality certificate has received the warehouse management notice, and it is necessary to go to the site for sampling and pass the sensory preliminary raw materials. The quality is judged, and the qualified admission is allowed (inspected area).
If the quality control department passes the inspection, the warehouse receipt will be issued, and the warehouse management unit can be notified that it can be put into storage (qualified inspection area); if it is unqualified, the impact on product quality is obvious, and the return notice will be issued to notify the purchasing department to return the goods. At the same time, submit a quality report to the production manager.
Emergency release. Raw materials supplied to qualified suppliers, such as the urgent need to produce raw materials for inspection, can be released urgently. The emergency release must be submitted by the production department, and the quality control department agrees and approves it by the competent manager. After clear identification and record, it is released, so that it can be returned and replaced in time if it is found to meet the specified quality requirements.
Concession to receive. The raw materials are unqualified, but the impact on the quality of the products is not obvious, and the production is urgently needed. In this case, the quality control department needs to fill in the “concession receiving application formâ€, and after the signature of the quality control manager, it is submitted to the competent manager for approval. In addition, the price of raw materials should be correspondingly lower.
Inspection and control plan for raw materials 1. Have the contract, the quality certificate provided by the raw material supplier, and the purchase order. At the same time, the content of the three should be consistent, in this case, the inspection of the raw materials is received. 2. Items that can be self-tested: sampling, sample preparation, inspection and analysis, analysis and test results, and laboratory test reports, and the inspectors and reviewers sign separately. 3. For the items to be inspected, fill in the sample form by the laboratory and send the qualified relevant department to entrust the inspection. 4. Review the work flow. 5. The objector (supplier or purchasing department) submits a re-inspection application, and the quality control department manager approves and accepts the application. 6. Self-inspection projects, re-sampling, sample preparation, inspection and analysis, analysis and test results, issue of laboratory reports, inspection personnel, auditors respectively signed. 7. It is possible to carry out self-inspection, but the application for re-inspection requires the sample to be sent for inspection. The sample is filled out by the laboratory, resampled, and sent to the qualified department to entrust the inspection. The inspection fee is borne by the supplier. 8. If there is any objection to the entrusted inspection result, it is necessary to conduct the entrusted inspection again. The laboratory will fill out the sample delivery form, re-sample, and send the qualified relevant department to entrust the inspection. The inspection cost shall be borne by the supplier.
Treatment results inspection
1. The results of the inspection are fed back to the relevant departments in the form of inspection reports, so that different results can be analyzed and processed in a targeted manner, and the judgment of passing or not is made.
2. Three possible processing results: qualified, allowed to enter the warehouse; unqualified, returned; unqualified, concession received.
Management of quality records 1. The quality control department fills in the quality records according to the requirements, and keeps them together with the original quality certification documents. Including: raw material label, product quality qualification list provided by the supplier, purchase order, warehouse receipt, laboratory test, etc. 2. The quality record requirements are correct, complete, clear and effective. 3. The inspection record must have a quality judgment result and be signed by the inspector and the auditor.
The certified inspectors should be familiar with and master the quality standards and testing methods of raw materials, and inspect the quality of raw materials according to the regulations. The inspectors are required to go through the training and hold the certificate--the feed inspection laboratory technician's employment certificate. Obtaining this certificate indicates that the inspectors have the basic qualities of competent testing and testing. At the same time, feed enterprises should also encourage inspection laboratory personnel to learn at work and work in learning. For example, the professional qualification of the feed inspection laboratory technicians, after the primary school has passed, it is necessary to encourage the examination intermediate level, the intermediate level has passed, and the examination should be encouraged.
Raw material storage control plan 1. Control of loading and unloading process (1) The loading and unloading worker accepts the management of the warehouse manager when loading and unloading raw materials. (2) The Loader should not carry it by hand when loading and unloading. Handle it gently during handling. Pay attention to whether the seal of the package is firm and the package is damaged. The above situation is found on the spot. (3) The loader shall not damage the mark. (4) After loading and unloading, clean up the site according to the requirements for storage of raw materials.
2. Control of storage process Environmental requirements of storage place: ( 1) Simple warehouse: Temporary storage of stable raw materials, such as stone powder, requires no water on the ground and rain. (2) Bulk raw material storage: places where bulk raw materials such as corn, soybean meal, cotton aphid, and secondary powder are stored, and are required to be ventilated, rainproof, moisture-proof, insect-proof, anti-mouse and anti-corrosion. (3) Additive raw material storage: In the place of storing trace elements, vitamins, pharmaceutical additives and other raw materials, in addition to ventilation, rain, moisture, insect proof, anti-rat and anti-corrosion, it is also required to prevent high temperature and protect from light. (4) After the daily work is completed, the warehouses should be cleaned, sorted and inspected, and problems should be dealt with in a timely manner. Disinfect the raw material storage site regularly.
3. Acceptance of raw materials in storage places (1) Before the raw materials are put into storage, the following inspections should be carried out: whether the packaging is complete, whether there is any damage, whether the contents of the physical and packaging marks and the contract are consistent, and whether there is a certificate of conformity. (2) Raw materials that do not meet the quality or to be inspected shall be clearly marked by the storage of the raw materials, isolated and properly kept. (3) Stacking requirements for warehousing materials. (4) The raw materials should be put into different warehouses, sorted and placed, and there should be a backing plate. There should be gaps between the concrete, and the raw material labels, including the product name, time, quantity and source, and in order, .
4. Management and inspection of raw materials in and out of the warehouse (1) Establish a complete account, card and material management system for the incoming materials, and store the raw materials for all incoming and outgoing materials in accordance with the prescribed procedures, check and change, and count once a month. To achieve the matching of the accounts, the report is reported to the relevant departments such as finance. (2) Strictly implement the principle of FIFO. When the material picking is produced, the picking voucher must be confirmed when it is confirmed, and the signing personnel sign. (3) The material storage clerk checks the warehouse every week, and records all the records. If the raw material is found to be damp, moldy, damaged by insects or rats, etc., and the quality of the raw materials is affected, it is necessary to take effective measures immediately and report to the quality control department that cannot be processed.
5. Management of expired warehousing materials
(1) When the raw material custodian regularly checks the stored raw materials for expiration, fill in the “Expired Raw Material Inspection Record†and report it to the Quality Control Department. The Quality Control Department conducts inspection and testing of expired raw materials.
(2) According to the “Expired Raw Material Inspection Record Form†and the test results, the Quality Control Department proposes a disposal plan, which is implemented after approval by the competent manager.
