Description
Technical Field
The utility model relates to the technical field of feed processing, in particular to a granular grain raw material grading utilization and cleaning system.
Background
The grain material (such as corn, wheat, barley, etc.) is the main energy material for producing compound feed, and is generally 40-70% of the compound feed. The production process of the feed comprises the procedures of raw material receiving, cleaning, crushing, mixing, granulating, puffing/expanding, packaging, finished product dispensing and the like.
The granular raw materials need to be treated by a cleaning process before being crushed, and the cleaning process designed in most of the existing feed processing plants has the following defects.
1. The cleaning process only uses a single-layer cylinder primary cleaning screen to clean large impurities such as bricks, stones and hemp ropes, the permanent magnet cylinder cleans magnetic metal impurities such as iron nails and screw caps, the cleaning of impurities such as dust, small impurities and broken corn grains is not considered, the harmfulness of mycotoxin in raw materials and the increase of mycotoxin in the raw materials in the storage process are not considered, and corresponding measures are taken; the grain raw materials can generate broken grains and powder in the processes of harvesting, storing, loading and unloading and the like, and the broken grains and powder without the seed coat protection are more easily corroded by mould to be polluted; the moisture condensation on the silo wall caused by the temperature difference change in the storage process of corns and the like in the vertical silo causes the stored raw materials to mildew and agglomerate, so the risk of mycotoxin increase in the storage process of the raw materials due to the powder, broken particles and mildew generated in the storage process; therefore, there is a need to consider the removal of broken pieces, flour and mold from corn prior to the comminution of the material, which is an efficient and cost effective method of reducing the mycotoxin level in the material.
2. The present feed mills have not paid much attention to the grading utilization of granular cereal materials and the reduction of mycotoxin content in the material cleaning process. The national standard of corn, wheat, brown rice, sorghum, barley, oat and other raw materials is graded according to the volume weight, the volume weight is the quality of raw material grains in unit volume, the volume weight is a key index for measuring the quality of granular grain raw materials, the completeness, uniformity, maturity and potential nutritional value of the raw materials such as corn and the like can be truly reflected to a certain extent, the higher the volume weight value is, the more nutrient substances are contained in the grains, the higher the quality grade is, the corn is the most common energy feed raw material for producing feed, the ratio in the compound feed is the largest, and formulators use the corn with high volume weight, namely high quality grade in high-end products such as young livestock and poultry and sow feed such as creep feed, piglet feed, early-stage feed for broiler chicken and laying hen, and the like, and use the corn with low volume weight in products such as medium-sized pig feed, meat duck and the like. After the volume weight is generally measured, the corn grains are classified and stored in different vertical silos or room-type silos according to different indexes such as the volume weight, impurities, moisture and the like, then the corn grains with different volume weights are classified and used when different livestock and poultry feeds are produced, so that the requirements of classifying and storing the corn grains can be met only by the vertical silos with enough quantity and the room-type silos with enough area, the corn grains, the wheat and the like belong to agricultural products, the corn grains and the wheat are sourced from thousands of households when being purchased, the product quality of the corn grains and the wheat have difference and instability, if the sampling quantity is insufficient or representative samples are not obtained when sampling is accepted, the classified storage of the corn grains, the wheat and other raw materials is difficult to accurately achieve, even if the corn grains with the same quality grade and the corn grains in different batches have different volume weights, therefore, the situation that the opposite silos for storing the corn grains, the wheat and the like are intensively stored and reduced when the raw materials are received is considered, The number of the room-type bins is required, corresponding equipment is equipped in the using process, certain technological measures are taken, the raw materials such as corn and the like which are stored in a centralized way are classified according to the volume weight, the purpose of classifying and utilizing the raw materials according to the grain raw materials can be achieved, the different requirements of different feed products on the volume weight are met, and the raw material resources are fully utilized.
3. The volume weight of the grain raw materials is highly related to the mycotoxin content, the pollution degree of the mould is different, the full degree of growth is different, the grain size and the maturity are different, the volume weight is different, the grain raw materials seriously polluted by the mycotoxin have correspondingly low volume weight, therefore, certain process equipment is adopted to classify the granular raw materials according to volume weight, the granular raw materials are divided into heavy raw materials and light raw materials, the separated raw materials with smaller volume weight are generally polluted to a higher degree by mycotoxin, the separated raw materials with larger volume weight are generally polluted to a lower degree by mycotoxin, and thus, the raw materials are classified according to the volume weight and the mycotoxin content, and the raw materials with different mycotoxin contents can be subjected to different process treatments to respectively reduce the mycotoxins, so that the method has the effect of achieving multiple purposes.
4. Mycotoxin in the granular cereal raw material is mainly attached to the epidermis of the raw material, and the content of the mycotoxin in the raw material can be effectively reduced by removing part of the epidermis of the granular raw material; the peeling process adopted by part of feed factories selectively peels all corns without aiming at the height of mycotoxin, adopts different process routes and operation parameters to peel corns with different quality grades, different mycotoxin contents and different purposes at different degrees, and has the problems of excessive peeling, insufficient peeling, incomplete separation of peeled corn husks and corns and mixing of the corn husks and the corns in the actual operation, the peeling effect is not ideal, and the raw material loss is high. Therefore, a flexible process route can be set, whether peeling treatment needs to be carried out or not is flexibly determined according to the mycotoxin content of the raw material, the corn with low mycotoxin content can be processed without peeling treatment, the corn with high mycotoxin content is processed through primary or secondary peeling treatment, harm of mycotoxin to animals can be effectively reduced, and meanwhile, the loss of the raw material is reduced. In conclusion, the corn subjected to volume weight grading and peeling treatment can be classified according to the volume weight and the mycotoxin content, different nutritional requirements of animals are met, the best use of the substances is achieved, and meanwhile, the feed production process has adaptability to processing of different raw materials.
