摘要： A cryogenic enhanced mechanical freezer system and method are provided. The disclosed system includes a mechanical freezer compartment adapted for freezing food products, a cryogen injection system adapted to directly inject cryogen into the mechanical freezer compartment, an exhaust system adapted to rapidly evacuate cryogen vapors from the freezer compartment; and a freezer control system adapted to operatively control the exhaust system and cryogen injection system in response to selected inputs. The selected inputs may include user inputs as well as inputs received from a temperature sensor disposed in the freezer compartment and a gas analyzer adapted to monitor concentrations of selected gases within the freezer compartment. Access to the freezer compartment is prevented during cryogen injection and when the atmosphere in the freezer compartment is not safe as determined by the gas analyzer.

摘要： The method of the invention is based on the comparison of local vapor concentrations at the inlet and outlet refrigeration ports and taking action based on that comparison. Control apparatus incorporating the invention is installed inside a refrigeration enclosure, adjacent to a port, preferably at the lowermost port. If the enclosure contains multiple ports at similar height, then each port has a form of the control apparatus attached to it. The control apparatus adjusts a flow of vapor leaving the interior of the enclosure. The control apparatus includes a duct assembly and a blower system. The bottom portion of the duct assembly is a tunnel enclosure through which a conveyor belt passes. Connected to an inside edge of the tunnel enclosure is a duct that extends upward from the conveyor belt. A blower for this duct either sucks vapor away from the conveyor belt or blows vapor from the enclosure interior toward the belt. Regardless of the flow direction, a vapor curtain forms inside the tunnel enclosure and represents a transitional region from all vapor to all air. Control of the blower for the duct assembly is based on vapor concentrations in the tunnel enclosures adjacent to each port. A microprocessor compares measured concentration levels and alters the blower motor frequency in such a manner as to minimize the difference in concentration levels at each port.
摘要翻译：本发明的方法是基于对入口和出口制冷端口的局部蒸汽浓度的比较，并基于该比较采取行动。结合本发明的控制装置安装在与端口相邻的制冷机壳中，优选在最下端的端口。如果机箱包含多个类似高度的端口，则每个端口都具有连接到其上的控制设备的形式。控制装置调节离开外壳内部的蒸气流。控制装置包括管道组件和鼓风机系统。管道组件的底部是输送带通过的隧道外壳。连接到隧道外壳的内边缘是从传送带向上延伸的管道。用于该管道的鼓风机将蒸汽从传送带吸入或从外壳内部朝向带吹送蒸气。不管流动方向如何，蒸气幕形成在隧道外壳内，代表从所有蒸气到全部空气的过渡区域。用于管道组件的鼓风机的控制基于与每个端口相邻的隧道外壳中的蒸汽浓度。微处理器比较测量的浓度水平并改变鼓风机电机的频率，以使每个端口的浓度水平差异最小化。

摘要： A cryogenic enhanced mechanical freezer system and method are provided. The disclosed system includes a mechanical freezer compartment adapted for freezing food products on a conveyor, a cryogen injection system adapted to directly inject cryogen into a shrouded zone proximate the conveyor in the mechanical freezer compartment, an exhaust system adapted to rapidly evacuate cryogen vapors from the freezer compartment; and a freezer control system adapted to operatively control the exhaust system and cryogen injection system in response to selected inputs so as to not adversely affect the mechanical refrigeration capacity associated with the mechanical freezer. The selected inputs may include user inputs as well as inputs received from one or more temperature sensors disposed in the freezer compartment and a gas analyzer adapted to monitor concentrations of selected gases within the freezer compartment. Access to the freezer compartment is prevented using a door interlock arrangement during any cryogen injection operations and when the atmosphere in the freezer compartment is not safe as determined by the gas analyzer.
