SENSOR-HEATING ELEMENT CONFIGURATIONS AND MULTI-LOOP CONTROL CYCLES FOR DRY-HEAT STERILIZERS

Methods and systems implement a dry-heat sterilizer configured to operate at temperatures permissive of a heat-intolerant articles and heat-intolerant packaging. To effectively and evenly transmit heat throughout a dry-heat sterilizer at such temperatures, the dry-heat sterilizer furthermore provides an electronic controller coupled to multiple sensor-heating element configurations, the electronic controller configured to compute proportional-integral-derivative (PID) terms to operate a multi-loop heat control cycle including at least a first feedback loop and a second feedback loop, and configured as an asymptotic PID controller for at least one feedback loop. In this fashion, the likelihood that spot airflow temperature at particular temperature sensors will overshoot a PID setpoint is substantially reduced. This results in spot airflow temperature at the temperature sensors being sustained at the PID setpoint asymptotically, substantially improving precision of heat control cycles.

Induction oven with selectable resonance frequency
11291085 · 2022-03-29 ·

An induction oven for the sterilization of equipment is disclosed. The invention effectively reduces sterilization cycle times from 90 minutes to less than 30 minutes using dry heat. In addition to increased efficiency, the dry heat also avoids pitting and other forms of degradation of the materials being sterilized. The oven can be configured by the user to generate a resonance of a particular frequency to target the specific type of metal or other induction material being heated. Target induction materials include cast iron, stainless steel, brass, and graphite, for example. The oven includes a coil that generates the time-varying electromagnetic field using a two-dimensional spiral having a rectangular pattern. The spiral coil is formed on a printed circuit board. The oven is configured to receive a container for heating articles. The container includes a bin, e.g., aluminum, and transparent lid with a gasket therebetween to produce an airtight seal. The container can be used to both sterilize equipment as well as store the sterilized equipment without contamination.
