Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a cell wall breaking technology for raw materials such as marine microalgae and spores. Background Technology

[0002] Plant-based natural active ingredient extracts are important ingredients in the food and beverage industry, playing a vital role in enhancing product functionality, nutritional value, and overall quality and added value. However, current conventional pulverization technologies, due to insufficient fineness, cannot effectively break down plant cell walls, severely limiting extraction efficiency. This is particularly true for globally recognized raw materials rich in various high-value bioactive components, such as microalgae, *Chlorella vulgaris*, and Ganoderma lucidum spores. Because their particle size is only 2-10 micrometers, effective cell-wall breaking methods have long been lacking, hindering the full utilization of their active ingredients.

[0003] Current technologies primarily employ dry grinding, but due to the small size, low mass, and low kinetic energy of materials such as microalgae and spores, the impact and shear energy density of dry grinding is insufficient to break down their cell wall structure. This results in low cell wall breakage rates and limited production capacity, making it difficult to achieve large-scale, high-efficiency production. Furthermore, the academic community has attempted various cell wall breaking technologies, including liquid nitrogen-assisted grinding, high-shear grinding, alternating freeze-thaw cycles, ultrasonic methods, and enzymatic hydrolysis. However, these methods have encountered insurmountable difficulties in terms of cell wall breakage rate, production capacity, and processing costs, severely limiting their application.

Through the extremely strong cavitation effect brought about by the ultra-high pressure jet, a jet cell-wall breaking effect is generated on plant cells, microalgae, spores, pollen, etc., thereby enabling the effective release of plant functional components and enhancing the efficiency of plant extraction.

[0005] To achieve the above objectives, this utility model provides an ultra-high pressure jet cell-breaking system, including a material buffer tank, an inlet booster pump, a plunger pump hydraulic end, an ultra-high pressure jet cell-breaking nozzle, a cleaning bypass valve, a plunger pump power end, an oil-cooled heat exchanger, a plunger cooling circuit, and an oil cooling circuit.
