Abstract
A supercritical extractor capable of bottom discharge comprises a cylinder, a cylinder top part equipped with a carbon dioxide outlet and an upper seal head and a cylinder bottom part. The supercritical extractor is characterized in that the lower portion of the cylinder bottom part is provided with an opening which is sealed by a lower seal head, a lower seal head fixture is further disposed at the joint of the lower seal head and the cylinder bottom part, wherein the top end of the lower seal head is equipped with a sieve plate and a sieve plate stand, the lower portion of the lower seal head is equipped with a pneumatic cylinder which is arranged on a cylinder support. The side face of the cylinder bottom part is equipped with a carbon dioxide inlet which is opposite to the region provided with the sieve plate stand. A discharging hose capable of being tightly sleeved with the cylinder bottom part is arranged. By employing the structural design of bottom discharge without hoisting charge materials from the upper by baskets, requirements to factory space are reduced, safety of the produce process is increased and production efficiency is increased by utilizing negative pressure to suck out extracted salvage stores to finish discharging operation. The extractor is adapted for material varieties having incompact extracted salvage stores, in particular adapt for extraction of European hop.
Description
Technical field
The utility model relates to a kind of separation equipment, relates in particular to the extractor that a kind of supercritical carbon dioxide extracting is used.
Background technology
Supercritical carbon dioxide extraction method is a kind of novel extraction technology that grows up the eighties, carbon dioxide is with its gentle critical condition, nontoxic, fire-retardant, cheap and easy to get, characteristics such as dissolubility is good and be specially adapted to the extraction of thermal sensitivity and bioactivator, thereby in food industry, natural perfume material, occupied leading position, cater to current society and advocated natural trend.
In the supercritical carbon dioxide extracting equipment, extractor is one of most important component, and its operating pressure is the highest during all devices is formed.At present most extractors uses rim, the solid material that the is extracted hoop of packing into when work, grid is arranged at the rim bottom, and has web plate to prevent that tiny material from spilling.During extractor work, hoop lifts into extractor from top inlet, again with the arrival end sealing, prevents that carbon dioxide from passing through between hoop and extraction wall.Extraction is opened seal cover after finishing also release, and hoop is hung out the replacing material.This extractor has following shortcoming: (1) hoop lifts from top, requires the factory building space than higher, has increased investment; (2) lift material continually, production security is relatively poor; (3) production automation degree is low, and charging, discharging is more loaded down with trivial details, reduced production efficiency.
Summary of the invention
The utility model purpose provides a kind of supercritical extract device of bottom discharge, and it has reduced the requirement to the factory building spatial altitude, and has improved the security of production process, has improved production efficiency.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of supercritical extract device of bottom discharge, comprise cylindrical shell, be provided with cylindrical shell top, the cylindrical shell bottom of carbon dioxide outlet and upper cover, it is characterized in that: below, described cylindrical shell bottom is provided with opening, opening part is sealed by low head, low head and junction, cylindrical shell bottom also are provided with the low head jig, the top of low head is provided with sieve plate support and sieve plate, and the below of low head is provided with cylinder, and cylinder is installed on the cylinder support; The side of cylindrical shell bottom is provided with carbon dioxide inlet, and carbon dioxide inlet is regional corresponding with placement sieve plate support; Other is furnished with the discharging flexible pipe that can be locked bottom cylindrical shell.
Described cylindrical shell bottom opening internal diameter is 0.3～0.8/1 with the cylinder internal diameter ratio.
The fairlead of cylinder piston also is housed on the described cylinder support.
The supercritical extract device of the above-mentioned bottom discharge that the utility model provides, owing to taked the bottom discharge structural design, feed from the top lifting without hoop, reduced requirement to the factory building spatial altitude, and the security that has improved production process, utilize negative pressure that the discharging operation is finished in the sucking-off of extracted residues material, improved production efficiency.This extractor is applicable to the material kind that extract remainder is more open, is particularly suitable for HOP EXTRACTION.
