Microbial feed fermentation equipment

Abstract

The invention discloses microbial feed fermentation equipment, which comprises a tank body, an outer spraying device, a box body and a fermentation liquid circulation device, wherein the tank body ishorizontally arranged on a support frame; a water collecting groove is formed in the bottom side of the tank body; the outer spraying device comprises a support rod, a water spray nozzle and a water box; the box body is arranged in an accommodating space; a fermentation cavity is arranged inside the box body; a plurality of water leaking holes are formed in the lower wall of the box body; the fermentation liquid circulation device comprises a water pump, a filter and an atomizer; the water pump pumps fermentation liquid from the water collecting groove and supplies the fermentation liquid to the filter; the filter supplies the filtered fermentation liquid to the atomizer; the atomizer atomizes the fermentation liquid and sprays the fermentation liquid on the raw materials. By aiming at theproblem of poor quality of feed obtained after the fermentation due to nonuniform humidity of upper layer and lower layer raw materials in the conventional fermentation tank, the microbial feed fermentation equipment is provided with the fermentation liquid circulation device for spraying the fermentation liquid in the water collecting groove on the raw material upper layer again; the fermentation liquid permeates from top to bottom; the uniform humidity of the upper, middle and lower layer raw materials is ensured, and the raw material fermentation balance is facilitated.

Description

technical field [0001] The invention relates to the technical field of fermented feed production equipment, more specifically, the invention relates to a microbial feed fermentation equipment. Background technique [0002] Microbial feed refers to the feed obtained by fermenting natural raw materials such as plant straws with microorganisms. Microbial feed can be used for poultry breeding, especially for herbivorous animals such as beef cattle. [0003] The fermenter is the equipment used to produce microbial feed. The fermented raw materials are loaded into the fermenter and then fermented normally to obtain the microbial feed. The existing fermentation tanks usually have the following problems: First, the raw materials still produce part of the fermentation liquid during the fermentation process. Due to the influence of their own weight, the fermentation liquid in the upper layer of fermentation raw materials runs down, resulting in too high humidity of the lower layer of ...

AI Technical Summary

Problems solved by technology

The existing fermentation tanks usually have the following problems: First, the raw materials still produce part of the fermentation liquid during the fermentation process. Due to the influence of their own weight, the fermentation liquid in the upper layer of fermentation raw materials runs down, resulting in too high humidity of the lower layer of raw materials and too dry of the upper layer of raw materials , the humidity of the fermentation raw materials in the upper and lower layers is inconsistent, resulting in inconsistent feed fermentation, and the quality of the feed is not good. Generally, the moisture content of the fermentation raw materials is 40-70%. The temperature is too high, but the cooling effect of opening the cover and ventilating is limited. Some raw materials will be burnt due to insufficient cooling and high temperature, and the microbial feed is usually anaerobic fermentation. The process of opening the cover and ventilating will lead to the growth of aerobic microorganisms , affecting the fermentation quality of the feed; in addition, the traditional fermenter needs to manually detect the temperature and humidity of the fermenter at regular intervals, lacking intelligent temperature control and humidity control systems
