Circulation pretreatment vibration blanking drying device for meat and bone meal feed production

Abstract

The invention discloses a circulation pretreatment vibration blanking type drying device for meat and bone meal feed production, which comprises a pretreatment box, a drying box, a centrifugal throwing device, a circulating feeding device, an inclined screen, a vibrating material plate and a hot air device. The raw material hits the impact plate to make the particle size of the raw material smaller, so the raw material that meets the requirements passes through the inclined screen and enters the drying box, and the raw material that does not meet the particle size requirements enters the fixed box, and is impacted by the cam on the elastic cloth Function, the blower blows the raw material into the pretreatment box, and performs circular centrifugal throwing and impact, and the raw material entering the drying box falls on the vibrating material plate. Since there are several vibrating material plates, the raw material The falling time is longer, which can fully contact with the hot air and increase the drying effect. In the hot air device, because the first nozzle and the second nozzle are staggered, the hot air is evenly distributed and the drying efficiency of the raw material is improved.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a circulating pretreatment vibration-blanking drying device for meat and bone meal feed production. Background technique [0002] Meat and bone meal is a product made from livestock carcasses, residual minced meat, bones, viscera, etc. that are not suitable for consumption in livestock and poultry slaughterhouses, and is cooked at high temperature, degreased, dried, and pulverized. In addition to a small amount of impurities that cannot be avoided in the normal production process, meat and bone meal is also mixed with products such as hair, horns, hooves, and feces. The crude protein of meat and bone meal is generally 50%-60%, and the amino acid composition is relatively balanced. The price is relatively cheaper than fish meal, and it is a high-quality substitute for fish meal. [0003] In the process of feed production, it is necessary to pretreat and dry the raw materi...

AI Technical Summary

Problems solved by technology

[0003] In the process of feed production, it is necessary to pretreat and dry the raw materials first. Traditionally, pretreatment and drying are completed on different equipment, so it takes a lot of processing time, and during the pretreatment process, If the raw materials cannot meet the particle size requirements, it is necessary to screen out the raw materials that do not meet the requirements, and then process these raw materials mechanically, which further limits the processing efficiency
