Method and device for pretreating raw materials of low-temperature water-soluble creep feed

Abstract

The invention discloses a method for treating raw materials of low-temperature water-soluble creep feed. The method includes the steps of raw material conditioning; expansion and dehydration; crushing; post curing; superfine crushing for standby. A device for pretreating the raw materials comprises a feeding and conditioning device, a crusher and a raw material bin. A steam pipe is disposed on the feeding and conditioning device. An outlet of the feeding and conditioning device is connected with an inlet of a expander. An outlet of the expander is connected with an inlet of the crusher. An outlet of the crusher is connected with an inlet of a cooling stabilizer. An outlet of the cooling stabilizer is connected with an inlet of a superfine crusher. An outlet of the superfine crusher is connected with the raw material bin. By the method and device for pretreating the raw materials of the low-temperature water-soluble creep feed, digestibility of the feed is increased while palatability of the same is unaffected. In addition the device is convenient to machine, and high in automation level.

Description

[0001] technical field [0002] The invention relates to an improvement in the production process of the teaching trough material, in particular to a raw material pretreatment method and device for the low-temperature water-soluble teaching trough material, which can improve the water solubility and digestibility of the raw material. Preliminary feed for suckling pigs. Background technique [0003] Teaching trough feed, commonly known as feeding or opening feed, refers to the feed used when pigs start feeding 5 days after birth to 10 days after weaning; in the current production of teaching trough feed, three methods are generally used for production: 1. The raw materials are puffed, pulverized, mixed and granulated to obtain granular finished products. In this production method, the raw materials are puffed, pulverized and mixed to form granules by a granulating machine. This granulation process improves the palatability. In general, the best feeding effect of particle-typ...

[0003] Creep feed, commonly known as feed or open feed, refers to the feed used by pigs from the time of feeding 5 days after birth to 10 days after weaning; in the current production of creep feed, three methods are generally used for production: 1. The raw materials are extruded, crushed, mixed, and granulated to obtain granular finished products. In this production method, the raw materials are extruded, pulverized, mixed, and then made into granules by a granulator. This granulation process improves the palatability. However, it has the disadvantage of low digestibility and absorption rate. In general, the best feeding effect of granular creep feed products can only be at the mid-range level; 2. The raw materials are crushed, mixed, and granulated to obtain granular Finished products, in this production method, the raw materials are not puffed, they are directly pulverized and mixed through a granulator to form granules. Although this granulation process has the advantage of improving the digestion and absorption rate, it has the disadvantage of poor palatability. Disadvantages; 3. The raw materials are extruded, pulverized, and mixed to obtain powdery finished products. In this production method, the raw materials are extruded and pulverized, and then directly become powdered finished products after mixing. This process, although it is beneficial to add some intolerable High-temperature raw materials, but still have the disadvantage of low digestion and absorption rate
