The high-pressure biological cell breaker is a process in which the plunger pump and the homogenization valve work together to refine and homogenize the materials in the homogenization valve area. The material is sucked in and pressurized by the piston pump, and under the action of the plunger, it enters the valve group with adjustable pressure, and after passing through a specific width of the flow-limiting gap (working area), the instantaneous depressurized material is ejected at an extremely high flow rate (1000 to 1500 meters per second), and collides on the collision ring of one of the valve components, producing three effects:
1. Cavitation effect The material compressed by the plunger accumulates extremely high energy, and the pressure is lost instantaneously when passing through the gap of current limiting, resulting in the release of high energy and causing cavitation, resulting in strong crushing and refinement of the material.
2. Impact effect When the material passes through the flow limiting gap, it hits the special collision ring at the above extremely high speed, causing the material to crush.
3. Shear effect When high-speed materials pass through the valve cavity channel and the flow limiting gap, strong shear will occur.
The high-pressure biological cell disruptor is supplied with two sets of homogenizing valves: one crushing valve and one emulsifying valve.
It can be installed in the primary homogenizing valve body or in the secondary homogenizing valve body.
An emulsion valve consists of an impact head (ceramic ball), a stainless steel impact ring and a tungsten carbide seat. The seat is double-sided, which can be used on both sides, and the service life is doubled.
Emulsion valves are commonly used to prepare emulsions, such as:
1. Chemical and pharmaceutical: wax emulsion, vitamin emulsion, intravenous emulsion.
2. Food and beverages: flavors, fruit and vegetable juices, vegetable protein drinks.
3. Dairy products: milk, ice cream, cream, flavored or fortified milk, yogurt.
The rupture valve consists of an impact head, a homogeneous valve seat and an impact ring. The material is tungsten carbide.
Crushing valves are commonly used in the biological industry, such as: cell wall breaking, algae breaking, etc.
