METHOD AND APPARATUS FOR PRESSURE PROCESSING A PUMPABLE SUBSTANCE

摘要

An apparatus and method for pressure processing a pumpable substance, such as a pumpable food product. In one embodiment, the apparatus includes a plurality of coupled pressure vessels, each having an inlet port to receive the pumpable substance, an outlet port to remove the pumpable substance, an isolator to pressurize the pumpable substance and a high-pressure port for receiving pressurizing fluid to bias the isolator toward the pumpable substance. The apparatus can further include blocking valves to limit the travel of materials that may leak through the inlet and outlet valves, a heat exchanger to heat and/or cool the pumpable substance, and/or a gas controller to add gas to the pumpable substance or remove gas from the pumpable substance. Cleaning, rinsing, and/or sanitizing fluid can be pumped through the entire system, including through the isolator to cleanse and/or sanitize.
