Fermented feed aerobic stability temperature real-time monitoring experimental device

Abstract

The utility model discloses a real-time temperature monitoring experimental device for aerobic stability temperature of fermented feed, belongs to the field of teaching experimental equipment, and aims to disclose an experimental device for monitoring temperature change of the fermented feed after unsealing in real time. The experimental device comprises a heat insulation cover plate, a heat insulation box, a heat insulation bottom plate and a sample drum. According to the device, the box and upper and lower cover plates are made of heat insulation materials with extremely low heat conductivity coefficients and adopt vent groove and vent hole design, so that the heat exchange phenomenon of heat produced in the secondary fermentation process and the outside environment can be eliminated while smooth air circulation is kept between a measured sample and the outside environment, and the realistic contradiction about ventilation and heat insulation in the conventional method is effectively solved; with the adoption of single multi-unit design, a plurality of samples can be subjected to the aerobic stability experiment simultaneously, and experiment efficiency, accuracy and parallelity are effectively improved; and the experimental device is simple in structure, affordable, convenient to operate and easy to process.

Description

technical field [0001] The invention belongs to the field of teaching experiment equipment. Background technique [0002] The aerobic stability of fermented feed refers to the ability of fermented feed to keep fresh and not deteriorate after the fermentation container is opened. When the fermentation vessel is opened and the fermented feed is exposed to the air, CO is produced due to the decomposition of lactic acid and residual soluble carbohydrates by aerobic microorganisms. 2 , At the same time, protein and amino acid are decomposed into ammonia or amine substances, and aerobic decay generates a lot of heat, which leads to mildew and spoilage of feed. Aerobic stability is the characteristic of fermented feed, so it is often used as one of the important indicators to evaluate the fermentation quality of fermented feed, especially silage, and is widely used in feed processing, herbivorous livestock production, and scientific research related to fermented feed.

Problems solved by technology

In the past, when this technology was used to evaluate the aerobic stability of fermented feed, the factors such as the container type, material, and heat insulation effect of the secondary fermentation of the feed were not uniform, which directly affected the accuracy of the real-time monitoring temperature, thus affecting the aerobic stability. The systematic error caused by the performance evaluation cannot meet the standardized requirements for the quality evaluation of fermented feed
