Various food processing methods and a food processing system minimize microbial growth while an animal, such as a chicken, is processed into food. During processing, temperature of an animal carcass and atmosphere surrounding the carcass are controlled by spraying gases and a mixture of ozone and water on the carcass, directing the gases through a passage in a wall to cool a processing area, and flowing the gases into atmosphere surrounding the carcass. Preferably, the gases include ozone and cryogenic gases recycled from a cryogenic freezer. The system uses a reduced amount of fresh water by recycling water used during food processing.

Food processing method and system

Food processing method

Apparatus and method for freezing food products including a first freezer section utilizing a liquid or solid cryogen and a second freezer section which utilizes cryogenic vapor from the first freezer section to complete the freezing operation, the first and second freezer sections being in a vertical arrangement to minimize floor space and improve cooling efficiency.

Method and apparatus for freezing food products

Apparatus and process for cooling harvested edible and non-edible plants and plant products with a cryogenic fluid wherein the plants and plant products are delivered to an on-site freezer which receives the cryogenic fluid and the cooled plants and plant products and at least a portion of the cryogenic fluid is sent to a transportation vehicle.

Field harvest cooling system

The present invention provides a food processing system and method for refrigerating articles of food. The food processing system includes at least two cooling stages formed by a cryogenic freezer and a hydrocooler. The cryogenic freezer receives the articles of food and transfers heat from the articles of food to the cryogen so that the articles of food are refrigerated. After the transfer of heat from the articles of food to the cryogen, the cryogen boils off to form cryogenic vapor. The hydrocooler receives the articles of food prior to the cryogenic freezer and transfers heat from the articles of food to supplied cooling water. Such heat transfer reduces the quantity of cryogen required to refrigerate the articles of food. Additionally, an eductor is connected to a pump and to vent line from the cryogenic freezer. The cooling water is pumped through the eductor to suction cryogenic vapor from the cryogenic freezer and to mix the cryogenic vapor and the cooling water prior to reception of the cooling water in the hydrocooler. Such mixing transfers heat from the cooling water to the cryogenic vapor to increase the heat transfer between the articles and the cooling water in the hydrocooler. As a result of such increased heat transfer, the amount of cryogen required in refrigerating the articles is further reduced The eductor and pump combination has general application to the cooling of articles.
