Beef electric-stimulation tenderizing instrument capable of outputting multiple waveforms

Abstract

The invention relates to a beef electric-stimulation tenderizing instrument capable of outputting multiple waveforms, relating to an electric-stimulation tenderizing technology in the field of meat industry. The beef electric-stimulation tenderizing instrument is an intelligent electric-stimulation tenderizing instrument and comprises an MCU (Micro Control Unit), a DC power circuit, an inverter circuit, a safety circuit, a D / A (Digital-to-Analog) conversion circuit, a keyboard input circuit, a liquid crystal display circuit, a buzzer, an EEPROM (Electrically Erasable Programmable Read-Only Memory), a serial port communication circuit and a stimulating electrode. An integral system comprising the MCU and electron devices positioned on the periphery of the MCU can accurately control a rectification circuit to rectify DC so as to generate multiple current waveforms for stimulating fresh beef, and the frequency, the peak value and the stimulating time of the current waveforms can be freely set within a range permitted by the beef electric-stimulation tenderizing instrument; the beef electric-stimulation tenderizing instrument generates waveform types as follows: DC, sine waves, triangular waves and square waves; the peak value range is 0-110 V, the frequency range is 1-450 HZ, and the timing range is 0-10 minutes. The invention furthest considers the difference of different varieties and parts of the beef, thereby achieving a better tenderizing effect.

Description

technical field [0001] The invention relates to a beef electric stimulation tenderization instrument. In particular, it relates to an intelligence that can generate a variety of waveforms, and the amplitude, frequency and stimulation time of various waveforms can be adjusted arbitrarily within a wide range, taking into account the differences of different varieties and parts of beef to the greatest extent, and achieving a better tenderizing effect. Electrical stimulation tenderizer. Background technique [0002] Electrical stimulation refers to the action of a certain voltage and frequency on the slaughtered cattle and sheep carcasses for a certain period of time. In 1749, Benjamin Franklin first performed electrical stimulation on post-slaughter turkeys. However, it was not until 1951 that Americans Harsham & Deathrage (U.S. Patent 2,544,681) and Renehler (U.S. Patent 2,544,724) first applied for patents for the application of electrical stimulation technology in the meat ...

AI Technical Summary

Problems solved by technology

[0004] The limitations of the existing electrical stimulation beef tenderization instrument are large volume, single waveform, non-adjustable frequency and amplitude, unstable work, low intelligence, etc., and cannot adapt to the tenderization needs of different varieties and parts of beef.
