Abstract: A continuous high-speed pickle injector is provided with improved productivity that can inject a liquid substance such as brine for curing, seasoning or the like into a block of meat such as pork, beef, livestock meat and the like continuously, and disperse the liquid substance uniformly. A pickle injector which can inject a liquid substance such as brine for curing and the like into a block of meat being conveyed continuously while gradually raising the injection pressure from 0 or a low pressure includes two or more injecting sections being able to repeat an injecting operation, that is, from the start to the completion of the injection of a liquid substance. The two or more injecting sections inject a liquid substance while moving at a speed synchronized with the conveying speed of a block of meat continuously being conveyed during the operation of injection. The timing of the injecting operation for each injecting section is controlled.
