Tube In Tube Pasteurizer

Suitable for heating and pasteurization of liquids (tomato and fruit juice). It is made up of tube in tube spira flow pipes for steam and products. Steam at the inlet with pneumatic valve controlled by a temperature indicator. It is possible to adjust the temperature from 50° to 150°C.Holding tubes provide a fixed volume of tubing to "hold" a product for a set period of time at a given flow rate. This is required for processes, like pasteurization, sterilization, thermal deactivation, or tempering, that require a dwell time at a given temperature.It is usually operated by air pressure working against a strong spring. If the temperature of heated milk falls below set temperature, air pressure is released and the valve snaps shut immediately. When the temperature is regained, air pressure builds up and the valve opens up for the forward flow to occur.
