Method of preparing pellet feed for weaning pigling

Abstract

The invention relates to piglet pellet feed preparation method which comprises the following steps: (1) micro pulverization and even mixing are conducted to complete feed through a conventional feed processing method; (2) the mixed complete feed micro powder is poured into an inclined rotary disk granulating machine, and vaporous adhesive nutrient broth is evenly sprayed on the complete feed micro powder in the disk granulating machine, to prepare spherical granular feed; (3) the spherical granular feed is spread on a mesh-belt drying machine, to be heated and dried; (4) the granular feed is cooled through a counterflow cooling method for conventional feed processing; the particles of the granular feed prepared by the method are more floppy and crispy; the method improves the palatability of piglets, meanwhile, improves the granulation efficiency, reduces the granulation energy consumption and saves the artificial cost of granulation.

Description

technical field [0001] The invention relates to a method for preparing feed, in particular to a method for preparing granular feed for suckling piglets. Background technique [0002] Existing disclosed pellet feed preparation technology for suckling piglets (Chinese Patent Authorization Announcement No. CN100362940C, Patent No. ZL200610011776.9, date of authorization announcement January 23, 2008), although this patent has solved the defect of pelleting technology for pellet feed for suckling piglets , the nutrient content of the pellet feed is increased while pelleting, but the hardness of the pellet feed for suckling piglets is too high, and the feed intake of the piglets from birth to 15 days old will be due to the high hardness of the pellet feed, which will cause the piglets to eat pellets. Feed palatability is not good, so there is the problem of insufficient feed intake of suckling piglets; [0003] In the granulation process of this patent, the granulation process o...

[0002] Existing disclosed pellet feed preparation technology for suckling piglets (Chinese Patent Authorization Announcement No. CN100362940C, Patent No. ZL200610011776.9, date of authorization announcement January 23, 2008), although this patent has solved the defect of pelleting technology for pellet feed for suckling piglets , the nutrient content of the pellet feed is increased while pelleting, but the hardness of the pellet feed for suckling piglets is too high, and the feed intake of the piglets from birth to 15 days old will be due to the high hardness of the pellet feed, which will cause the piglets to eat pellets. Feed palatability is not good, so there is the problem of insufficient feed intake of suckling piglets;

[0003] In the granulation process of this patent, the granulation process of using a swing granulator or a rotary granulator consumes a lot of labor, and requires the cooperation of multiple people to mix the raw materials first, and then carry out the granulation process of the mixed raw materials, and the granulation equipment high energy consumption

[0004] The patented drying process uses a fluidized bed or mesh bed for drying, which causes energy waste due to the inherent characteristics of the fluidized bed or mesh bed equipment
