摘要： Anti-swirl baffles are provided in a mass transfer column to reduce the swirling motion of a vapor or mixed phase feed stream introduced into the column. The column is of the type having an upper region of a preselected diameter, a lower region of reduced diameter, and an intermediate transition region that has a diameter that transitions from the preselected diameter of the upper region to the reduced diameter of the lower region. The column includes a vapor or mixed phase feed nozzle and a feed device such as a vapor horn located at least partially within the upper region for delivering the vapor or mixed phase feed stream into the column. The anti-swirl baffles are positioned in the intermediate transition region of the column to disrupt the swirling motion of the vapor or mixed phase feed stream as portions of it descend from the feed device into the transition region of the column. An annular shield positioned in the transition region and spaced inwardly of the column shell defines a liquid flow passage that is shielded from the swirling motion of the vapor or mixed phase feed stream to reduce liquid entrainment.

摘要： A mass transfer column includes a feed device that is used to de-entrain liquid and more uniformly distribute vapor across a horizontal cross section of the column after a vapor or mixed phase stream has been directed into the column through a radially oriented feed nozzle. The feed device includes an annular passageway formed in the spacing between the column shell and an inner wall spaced inwardly from the shell. A deflector with oppositely directed deflecting surfaces is positioned at an inlet from the feed nozzle to the annular passageway and splits the vapor or mixed phase stream into two roughly equal streams that flow in opposite circumferential directions in the annular passageway. At least one pair of turning vanes is spaced on opposite sides of the deflecting surfaces in the annular passageway to create subpassages through which the vapor or mixed phase stream flows. The subpassages reduce the amount of vapor or mixed phase stream flow that impacts against the inner wall of the feed device at the inlet. The turning vanes unexpectedly reduce the pressure drop that occurs as the vapor or mixed phase stream is redirected from its radial entry direction to the circumferential direction in the annular passageway. By reducing the pressure drop, improvements in product yield and vapor distribution can be achieved.

摘要： Systems and processes are described for sanitizing a food product with ozone gas. The ozone gas is generated using a low pressure, low volume ozone gas generator and is delivered to a fluid injector. The fluid injector receives high pressure carrier fluid from a carrier fluid source and causes the ozone to be entrained in a stream of carrier fluid. The entrainment is created by passing the carrier fluid through a venturi diffuser inside the injector which creates a negative pressure in the sanitizing fluid line, thus drawing the sanitizing fluid into the carrier fluid and creating a highly homogenized fluid jet. The fluid jet is then injected into a container which contains a food product to be sanitized by the ozone. The container may also be provided with a mixing paddle to vigorously mix the food product while the ozone/carrier fluid jet is injected into the food product, which further ensures that the food product is contacted with sanitizing ozone gas. The container can be sealed to be pressurized by the ozone/carrier fluid jet by selective opening and closing of a vent. The ozone/carrier fluid jet may also be selectively humidified before injection into the container.
摘要翻译：描述了用臭氧气体消毒食品的系统和过程。臭氧气体使用低压，低容量的臭氧气体发生器产生，并被输送到流体注入器。流体注射器从载体流体源接收高压载体流体并且使臭氧被夹带在载体流体流中。夹带是通过使载体流体通过喷射器内的文丘里扩散器而产生的，其在消毒流体管线中产生负压，从而将消毒流体吸入载体流体并产生高度均质化的流体射流。然后将流体射流注入含有要被臭氧消毒的食品的容器中。容器还可以设置有混合桨，以在将臭氧/载体流体射流注入食品中时剧烈混合食品，这进一步确保了食物与消毒臭氧气体接触。容器可以通过选择性地打开和关闭排气口被密封以被臭氧/载体流体喷射器加压。臭氧/载体流体射流也可以在注入容器之前被选择性地加湿。
