High-temperature and high-pressure steam instantaneous variable-pressure sterilization device and application

Abstract

The invention belongs to the technical field of food processing equipment, and relates to a high-temperature and high-pressure steam instantaneous variable-pressure sterilization device and application thereof. The sterilization device comprises a sterilization kettle, a turnover door, a steam input pipe, a stop valve, a decompression valve, a pressure stabilizing system and a PID control system; the sterilization kettle is provided with an internal through sterilization kettle cavity, and turnover doors are arranged at openings in the two sides; a plurality of groups of steam input pipes are communicated with the upper wall surface of the sterilization kettle, and stop valves I are arranged on the steam input pipes; the sterilization kettle is also communicated with the decompression valve and the pressure stabilizing system; the pressure stabilizing system is beneficial to accurate control of pressure, and the sterilizing effect is prevented from being influenced by unstable pressure. According to the invention, sterilization can be completed within seconds; on one hand, all microorganisms including spores can be killed; on the other hand, the color, luster and integrity of the food are not damaged, the nutritional value of the food is guaranteed, and an important guarantee is provided for prolonging the shelf life of the food.

AI Technical Summary

Benefits of technology

This patented design simplifies its construction while improving work efficacy. It includes two parts: a heated water vessel with a separate lid that controls how well it's filled up when closed, and a mechanism called a dispenser used to distribute vaporized liquid into small bags inside this tank. These mechanisms help keep everything clean during operation without being affected or losing their effectiveness overtime. Additionally, there are several technical improvements such as a regulatory system made possible through servo control and sensors, ensuring consistently accurate pressures at different points throughout the process.

Problems solved by technology

This patented technical problem addressed by this patent relates to improving the long-term preservation (shelf) period and quality of crops like wheat, rye, barley, bean, pea, sorghum, cereals, fava seeds, nuts, seafood, vegetables, bread crumbles, saffron berries, tomatoes, yogurt, milk, fish), while ensuring consistence with consumer preferences over their taste budgets during consumption.
