Apparatus for continuous extracting and sterilizing solid materials under high and ultrahigh pressure

Abstract

The invention relates to the area of chemical separation and biological engineering mechanical device, which especially provides a high-pressure ultrahigh-pressure continuous solid material extraction and disinfection device. The invention is formed by a bearing cylinder, a material chamber chain, a material chamber driving device, a heat exchanger, a liquid inlet pipeline and a liquid outlet pipeline. Wherein, the material chamber chain is mounted inside the bearing cylinder; the material chamber operation driving device is mounted at the two ends of the inlet and outlet of bearing cylinder to connect the material chamber chain that entering the bearing cylinder; and the bearing cylinder is mounted with a heat exchanger, a liquid inlet pipeline and a liquid outlet pipeline. The invention has reasonable structure, which can realize continuous extraction and disinfection of solid material in high-pressure and ultrahigh-pressure, to confirm the continuous operation of using ultra-critical liquid to extract solid material and ultrahigh-pressure to disinfect. The invention has high producing efficiency, safety, reliability and low energy consumption and producing cost with environment pollution.

Description

1. Technical field [0001] The invention belongs to the field of chemical separation and bioengineering mechanical equipment, and in particular relates to a high-pressure ultrahigh-pressure continuous solid material extraction and sterilization device. 2. Background technology [0002] High-pressure ultra-high pressure extraction and sterilization unit operations mainly include: supercritical fluid extraction and ultra-high pressure biological sterilization technology, which generally involve various solid material processing devices. At present, most of this type of high-pressure and ultra-high-pressure devices are intermittently operated with quick-opening sealing structures. These structures generally include flange type, clamp type, toothed type, split ring type, etc. The production efficiency of the device with this structure Low, the labor intensity of workers is high, and there is a large amount of energy loss every time loading and unloading materials; in addition, on...

Problems solved by technology

At present, most of this type of high-pressure and ultra-high-pressure devices are intermittently operated with quick-opening sealing structures. These structures generally include flange type, clamp type, toothed type, split ring type, etc. The production efficiency of the device with this structure Low, the labor intensity of workers is high, and there is a large amount of energy loss every time loading and unloading materials; in addition, once the self-locking of the quick-opening sealing structure fails, it will easily cause a catastrophic explosion accident, and there is a potential safety hazard

Although some work has been done on continuous high-pressure and ultra-high pressure solid material extraction and sterilizing devices at home and abroad, very significant results have not been obtained. The key constraints lie in the dynamic sealing of high-pressure and ultra-high pressure and the structure of feeding and discharging materials. on the drive
