The check experiment of the real-time monitoring experiment device of the utility model fermented feed aerobic stability temperature
Experimental design and method:
Test one test material of choosing is the maize stalks straw ensiling that utilizes the maize stalks straws of just gathering in the crops into after cooked maize; Test two experiment materials of choosing are whole corn silages.Two kinds of test ensilages are all through 45 days anaerobic fermentations, adopt V-score ensilage fermentation quality evaluation system to be judged to be the ensilage of high-quality fermentation behind Kaifeng.The control group of two tests is all to use conventional vinyon bucket as the test that takes up container and carry out; And the test of test group for using fermented feed aerobic stability determinator to carry out.Conventional vinyon bucket and fermented feed aerobic stability determinator inner bag volume are 1L.Test adopts Multi-channel temperature recorder to carry out recording occurring continuously to the central temperature of two kinds of test chambers.Three repetitions are carried out in each test.
Results and analysis:
Figure 10 has shown the variation of maize stalks straw ensiling Kaifeng after fermentation container center temperature with ingress of air time.Test group 81h behind Kaifeng of test one reaches 33.17 ℃, forms single heating peak.This secondary fermentation with single heating peak belongs to the secondary fermentation type being caused separately by mould.Though control group forms heating top at 78 ~ 81h, temperature only reaches 24.1 ℃.And behind Kaifeng, after 132h, formed a little heating peak, but temperature is still lower, and only exceed 3.3 ℃ of room temperatures.First heating of control group is almost synchronizeed with test group rush hour, and just temperature is lower.Can judge that control group belongs to the independent type secondary fermentation of mould equally.Although control group occurs heating peak again in the exposure later stage, this does not belong to fermented feed examines due to character certainly, but because control group has been used open type plastic containers, it is caused that feed surface and air contact portion have infected extraneous saccharomycete.
Figure 11 has shown the variation of whole corn silage Kaifeng after fermentation container center temperature with ingress of air time.In test two, test group has formed respectively two heating peaks after Kaifeng 58h and 277h.This secondary fermentation with two heating peaks belongs to the yeast-mould bacterial type secondary fermentation by saccharomycete and mould priority alternating action.It is theoretical that this result of the test meets classical secondary fermentation.And the control group that adopts conventional vinyon bucket to carry out has formed the secondary fermentation trend similar to test group too, just the temperature in whole secondary fermentation process is always lower than test group.This is mainly because the heat insulating effect of control group is not as test group, causes round central temperature to be lost to outside by container outer wall.
