Abstract:

A cryogenic freezing method uses a mixture of liquid nitrogen and liquid oxygen in amounts approximating the composition of atmospheric air to freeze food products. The mixture preferably includes 18% to 25% oxygen and the balance nitrogen, with small amounts of residuals which are commonly found in air. The present invention involves replacing a liquid carbon dioxide or liquid nitrogen cooling medium which is used in known cryogenic freezers with a liquid nitrogen and liquid oxygen mixture. The liquid nitrogen and oxygen mixture can be used according the present invention in many of the known freezers using liquid carbon dioxide or liquid nitrogen as a cooling medium, including tunnel freezers, spiral freezers, and immersion freezers. The use of a liquid nitrogen and liquid oxygen mixture improves the efficiency of a freezer because the cold vapors are not exhausted from the freezer. In addition, the leakage of vapors from the freezer into the room air will not create unsafe conditions for workers.

Abstract:

A vaccination record is provided. Initially, when a patient gets a vaccine, such as a COVID-19 vaccine, an indication of the vaccine is stored in an electronic file or data structure associated with the patient called a vaccination record. The record may include information such as the type of vaccine that was administered, the date that the vaccine was administered, and an indication of the entity (e.g., clinician or healthcare practitioner that performed the vaccine). The record of the vaccine may be created in response to a billing submission by the entity. Later, the patient may use the vaccination record to provide proof to third-party verifiers that the patient in fact received the vaccine.
