Wall-mounted ultrasonic enhanced fermentation device suitable for large fermentation tank and fermentation method of wall-mounted ultrasonic enhanced fermentation device

Abstract

The invention belongs to the field of bioengineering equipment, and relates to a wall-mounted ultrasonic enhanced fermentation device suitable for a large fermentation tank and a fermentation method thereof, the wall-mounted ultrasonic enhanced fermentation device comprises a fermentation tank, an ultrasonic transducer bracket, a bracket connecting piece, an ultrasonic transducer, a high-frequency connecting wire, a stirring shaft, a stirring paddle, an ultrasonic generator, an ultrasonic vibrator and a stainless steel welding short pipe; the stirring shaft is arranged in the tank body and is coaxial with the fermentation tank; a stirring paddle is arranged at the other end of the stirring shaft; a plurality of ultrasonic transducer brackets are arranged in the fermentation tank in an array manner, a plurality of ultrasonic transducers are arranged on the ultrasonic transducer brackets, and a plurality of ultrasonic vibrators are arranged on the inner walls of the ultrasonic transducer brackets; and the ultrasonic vibrator is electrically connected with the ultrasonic generator through a high-frequency connecting wire. The device disclosed by the invention solves the problems that the fermentation promoting effect is not obvious and the product quality is not stable due to the fact that ultrasonic waves of a traditional ultrasonic fermentation device are easy to attenuate and non-uniform in action.

Description

technical field [0001] The invention belongs to the field of biological engineering equipment, and particularly relates to a wall-mounted ultrasonic intensified fermentation device suitable for large-scale fermentation tanks. Background technique [0002] Due to the long period of growth and reproduction of microorganisms and the low rate of material exchange between fermentation substrates and microorganisms, the fermentation period is very long and the yield of products is also low, which is an important hindering factor for bio-fermentative transformation. [0003] As a physical method, ultrasonic waves are widely used in strengthening the value-added processing of agricultural products. Ultrasound has shown outstanding application value in the extraction of active ingredients of agricultural products, food sterilization, cell disruption, homogeneous emulsification, and promotion of heat and mass transfer. Especially in the promotion of fermentation by ultrasound, it also...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a wall-mounted ultrasonic intensified fermentation device suitable for large-scale fermentation tanks. By hanging multiple groups of ultrasonic transducers on the inner wall of the fermentation tank in a balanced manner, they can directly act on the fermentation liquid and overcome the problems caused by the thickness of the large-scale fermentation tank. The sound energy attenuation is serious, and the ultrasonic effect is not uniform due to the large diameter and height of the fermenter, so as to avoid the problems that the traditional ultrasonic assisted fermentation device has no obvious effect on promoting fermentation in large fermenters, and the product quality is unstable.
