The effect of vibration massage on the salting process of ostrich meat

Abstract

Existing massagers are characterized by relatively high energy consumption during operation, the metal consumption of the structure, complexity of the drive mechanism. Therefore, the search for effective implementation schemes of mixing operations and uniform structure formation of viscous and elastic-plastic raw materials, in particular, minced meat, subject to increased contact interaction while minimizing the force on the products, is relevant to the conducted research. The purpose of this work is to substantiate the technological preparation modes of the given minced meat with the use of a developed vibrating massager, as well as to determine the kinematic parameters of the oscillation system and graphic-analytical analysis of their change. The experimental model of the vibrating massager with an eccentric drive mechanism, a measuring evaluation base of rheological characteristics of the minced ostrich meat, and kinematic parameters of the vibrating drive of the massager, in particular, amplitude-frequency and speed characteristics were developed to carry out the specified tasks. High technological results were obtained when using the forced eccentric drive of the massager, which is characterized by a minimum mass of the oscillation masses of the parts compared to traditional unbalanced vibrators, which allow reducing 2 - 2.5 times the energy consumption to drive the vibrating massager under study. The practical value of the conducted work includes the use of the eccentric forced vibrating exciter for obtaining the force control over the minced meat to be formed, which reduces the oscillation masses of the drive and minimizes the energy consumption for the process, accordingly; it has the simplest structure among the mechanical vibrators, significantly reduces the dynamic loads on the supporting units of the vibrator as well as provides a sufficiently high contact interaction for both the vibration impact and the processing intensity in general.
