Description

Material crushing device for low-temperature fermentation Technical Field The utility model relates to the technical field of low-temperature fermentation, in particular to a material crushing device for low-temperature fermentation. Background Corn stalks and cow dung are common agricultural wastes, but the carbon-nitrogen ratios of the corn stalks and the cow dung are different. The corn stalk has high carbon content and high nitrogen content, and the carbon-nitrogen ratio can be adjusted after the corn stalk and the cow dung are mixed, so that the microbial activity is facilitated. By reasonably controlling the proportion and the fermentation conditions, the low-temperature fermentation of the corn straw and the cow dung can efficiently convert the waste, and the ecological and economic benefits can be realized. Low temperature fermentation technology has been widely used in recent years, and low temperature fermentation generally refers to a fermentation process in an environment of 15-30 ℃, and mainly depends on the activities of medium-temperature type and low-temperature type microorganisms. After the corn stalk (high carbon) and cow dung (high nitrogen) are mixed, a proper nutrition environment is provided for microorganisms by adjusting the carbon nitrogen ratio (C/N). Therefore, low-temperature fermentation is becoming an important process, and the advantage of low-temperature fermentation is that it can effectively inhibit the growth of certain harmful microorganisms, and can increase the yield and activity of certain target products. However, low temperature fermentation requires high material handling requirements, especially for the comminution of the material prior to fermentation, to ensure uniformity and proper particle size to facilitate microbial growth and metabolic activity. Because the existing material crushing device cannot effectively control the equipment temperature in the crushing process, heat generated in the crushing process cannot be dissipated in time. Such an increase in temperature may adversely affect the low temperature fermentation material. Firstly, the material may be degraded with heat sensitive components in a high temperature environment, which results in the degradation of the quality of the fermentation raw material, even the influence on the growth and metabolism of microorganisms, and the fermentation effect is reduced. Secondly, too high a temperature may also damage the cellular structure of the crushed material, affect the uniformity and dispersibility of particles thereof, and further affect the utilization rate of microorganisms to the material in the fermentation process, thereby reducing the yield and quality of the final product. In addition, instability in the temperature of the equipment may also increase the risk of mechanical failure, such as increased wear of bearings, cutters, etc. due to overheating, thereby shortening the useful life of the equipment. Under continuous operation for a long time, the smashing device lacking an effective temperature control means can also generate overheat phenomenon, so that energy waste is caused, and the production efficiency is reduced. For this purpose, a material pulverizing device for low-temperature fermentation is proposed.
