  • Patent number: 12239134
    Abstract: Compositions and methods that utilize a combination of essential oils or other plant-derived extracts or compounds and an emulsifier as an antimicrobial are provided. In some embodiments the compositions further include ozone. In some embodiments, the composition includes one or more plant essential oils, plant extracts, or plant-derived compounds, or combinations thereof, and an emulsifier (such as a saponin). The antimicrobial composition may also include water, peracetic acid, acetic acid, lactic acid, citric acid, and/or hydrogen peroxide. Methods of killing a microorganism, including contacting the microorganism with the disclosed antimicrobial compositions are also provided. The microorganism may be present on a food item or a food contact of non-food contact surface and may be in the form of a biofilm. In some examples, the antimicrobial composition is used one or more times (such as 1 to 5 times).

  • Patent number: 11890661
    Abstract: The present disclosure relates to an electromagnetic stamping method and an electromagnetic stamping device. The electromagnetic stamping method includes: dividing a blank holder of a stamping device into a plurality of blank holder areas based on a contour characteristic of a workpiece to be stamped; setting a blank holder force function over time for each blank holder area based on a shape characteristic of the blank holder area; collecting blank holder force data of each blank holder area every cycle period t0, and calculating an error between the blank holder force data and a value of the blank holder force function at a current time; and controlling a blank holder force for each blank holder area based on the error, and obtaining the workpiece to be stamped by stamping sheet material under the blank holder force.

  • Patent number: 11803167
    Abstract: Disclosed are an energy service system of a multi-machine production line and a control method thereof, the method includes reorganizing respective machines in the production line into three types of controllable entities: a drive system, an energy supply bus and an execution device, equipping them with a control center, and selecting a sub-drive system that is idle and is capable of completing the work stage with high energy efficiency to supply energy service for the corresponding execution device through the energy supply bus. Further disclosed is a design method of a multi-machine shared drive system of a production line, which increases the number of basic flow units of each drive unit to a maximum value one by one, and coordinates action time to form a variety of scheduling schemes, and selects a configuration scheme whose total time and total energy consumption are less as the shared drive system.

  • Publication number: 20220039411
    Abstract: Antimicrobial compositions derived from edible plant sources such as essential oils, their active components, spices and plant extracts have shown antimicrobial effects against a number of foodborne pathogens. The foodborne pathogens of concern in meat and poultry products include Salmonella enterica, Escherichia coli O157:H7 and Listeria monocytogenes. The antimicrobial compositions were applied to a meat surface using liquid or powder electrostatic spray systems to effectively reduce the amount of pathogens on various meat and poultry products.
