Technical Field

The invention relates to the technical field of ganoderma lucidum spore production and processing, in particular to an injection pump device for supercritical CO2 fluid extraction of ganoderma lucidum spore powder.

Background

Ganoderma spore is the seeds of Ganoderma lucidum which is the tiny egg-shaped germ cells ejected from Ganoderma lucidum fold during the growth and maturation period. Ganoderma spore is brown powder, and has extremely fine appearance, because spore oil exudes after wall breaking, causing the situation of lump formation. Therefore, the spore oil needs to be separated from the spore powder to obtain the ganoderma lucidum spore powder with high purity.

Since the supercritical CO2 fluid has liquid-like fluidity and gas-like diffusivity and strong solubility, and is very suitable for extracting and separating the spore oil in the spore powder, the supercritical CO2 fluid is usually injected into an extraction kettle with the spore powder by using an injection pump device to perform the separation and extraction operation.

In the prior art, the injection pump device mainly comprises an injection pump and a hydraulic assembly for providing hydraulic oil for the injection pump to realize energy transmission, and the hydraulic assembly mainly comprises a hydraulic cylinder and an oil tank. A large amount of heat is generated on an oil return pipe between the hydraulic cylinder and the oil tank in the energy transfer process, the temperature of hydraulic oil can be continuously increased if the heat cannot be timely dissipated, and when the temperature of the hydraulic oil is too high, the sealing element of the injection pump device can be greatly damaged. In order to solve the above problems, an air-cooled radiator is usually installed in the middle of an oil return pipeline between a hydraulic cylinder and an oil tank of the injection pump device, but the air-cooled radiator has a poor heat dissipation effect on hydraulic oil, and thus the use requirement of people on the injection pump device cannot be met gradually.
