Online HVPEF (high-voltage pulsed electric field) treatment chamber for non-thermal sterilization of meat products

Abstract

The invention discloses an online HVPEF (high-voltage pulsed electric field) treatment chamber for non-thermal sterilization of meat products, and the treatment chamber is characterized in that an air cylinder is arranged on the lower end face of an upper bracket, one ends of two guide rods are respectively vertically arranged on the lower end face of the upper bracket on both sides of the air cylinder, the two ends of a mechanical arm are in sliding fit with the guide rods, the mechanical arm is provided with an upper treatment chamber, the upper treatment chamber is connected with a piston rod of the air cylinder, and the upper bracket is also provided with a controller; and a chain drive motor is arranged on the lower end face of a lower bracket, driven sprockets (a set of two) are respectively arranged on the lower end face of the lower bracket on both sides of the motor, the chain drive motor drives two sets of drive chains to carry out circulating rotation by virtue of the driven sprockets, the two sides of the lower bracket are symmetrically provided with a pair of photoelectric sensors, and the two sides of the drive chains are equidistantly provided with a plurality of lower treatment chambers. By using the online HVPEF treatment chamber disclosed by the invention, the uniformity of electric field distribution in a treatment cavity is ensured; and due to an adopted circulating cooling structure, the temperature of an electrode is reduced, the temperature rise of meat products in the process of treatment is reduced, the continuous operation of a sterilization process is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a solid-state food sterilization device based on high-voltage pulse electric field technology, in particular to an online high-voltage pulse electric field treatment chamber for non-thermal sterilization of meat products. Background technique [0002] Meat consumption and consumption structure are important indicators to measure the living standard of a country's people. At present, my country has become the world's largest meat producer. In 2010, my country's total meat output reached 79.25 million tons, an increase of 3.6% over the previous year. In 2010, the scale and total number of enterprises of livestock and poultry slaughtering and meat processing reached 4,054, and enterprises above designated size accounted for 20% of the total number of meat enterprises. It is estimated that by 2015, my country's total meat output will reach 86 million tons, and the per capita meat consumption will be 61 kg, making it the country wi...
