Google Patents US7614410B2 - Chemical concentration controller and recorder Meets all PMO requirements for HTST, HHST, and UHT applications.US7614410B2 - Chemical concentration controller and recorder.Hot product, cold product, hot water, and flow-rate all recorded and/or controlled in a single unit.New four color recording technology prints all trends, scales, events and customer specific messages on a plain paper, 12' chart.The standard color for this function is black. Range can be configured in percent flow or engineering units (GPM etc.). This option can include Recording (SFLR) or Recording and Control (SFLRC). Now available with a Safety Flow Limit function for systems with meter based timing. The standard color for this variable is blue. The range for this function is programmable to provide maximum readability in the product range while including CIP temperature. For multiple divert applications, separate hot water setpoints can be programmed to be selected automatically when the diversion setpoint is changed.Ĭold product can be optionally specified for Recording (CPR), or Recording/Controlling (CPRC). This variable is normally displayed and controlled, but not recorded. The unit can be optionally specified to include hot water control (HWC). When configured for multiple divert, the activated setpoint temperature is continuously printed in green. The hot product scale, temperature, and flow diversion valve frequency trend are printed in red. The STLR monitors sensor balance between the two elements to insure failsafe operation. Product temperature is monitored via our time proven dual element, 1,000 ohm RTD sensor. Remote selection of these setpoints is available as an option. The standard unit provides legal Safety Thermal Limit Recorder (STLR) functionality with up to 5 selectable diversion setpoints. Each scale is color coded to its' trend pen to provide a chart that is simple to read, even with multiple variables. This is accomplished via a unique, four color printing technology which prints on plain paper, 12', 100 division charts.Įach unit is programmable for up to 4 independent recording ranges and input types.

The unit combines failsafe protection for the pasteurization process with the broadest range of configuration options ever available in an HTST control package. The AV-9900 HTST recorder controller is specifically designed for use in continuous pasteurization applications.
