Both cyclic electrical current and changing magnetic fields can be converted into physical vibrations by magnetostrictive devices and piezoelectric transducers, respectively.<\/p>\n\n\n\n<p>while the <strong>power supply<\/strong> provides the energy needed to generate the waves.The energy for the system, which is typically an electrical current, comes from the electrical power generator. <\/p>\n\n\n\n<p>The <strong>control unit<\/strong> regulates the intensity and frequency of the ultrasound waves. It contains emitters like sonotrodes, horns, etc as discussed below.<\/p>\n\n\n\n<p>Emitters are crucial in ultrasound processing and can take various forms, including baths, horns, or sonotrodes. Unlike emitters, airborne ultrasound systems do not require any physical components. Baths typically consist of a tank equipped with one or more transducers that emit ultrasound waves into the sample. <\/p>\n\n\n\n<p>Horns can be attached to transducers to increase the signal&#8217;s strength and apply it directly to the food. Additionally, sonotrodes can be attached to the horn&#8217;s tip to further amplify the ultrasonic wave into the sample. <\/p>\n\n\n\n<p>The shape of the horn and the inclusion of a sonotrode determine the degree of amplification. Typically, sonotrodes are made of titanium due to its light mass, allowing for more efficient energy transmission, and high rigidity, ensuring durability. Common sonotrode shapes include knives, nozzles, and dies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Does_Ultrasound_Processing_Work\"><\/span>How Does Ultrasound Processing Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"360\" height=\"555\" src=\"https:\/\/vishalfoodtech.com\/wp-content\/uploads\/2023\/05\/image-3.png\" alt=\"\" class=\"wp-image-1009\" srcset=\"https:\/\/vishalfoodtech.com\/wp-content\/uploads\/2023\/05\/image-3.png 360w, https:\/\/vishalfoodtech.com\/wp-content\/uploads\/2023\/05\/image-3-195x300.png 195w\" sizes=\"auto, (max-width: 360px) 100vw, 360px\" \/><\/figure><\/div>\n\n\n<p>Ultrasound processing works by applying high-frequency sound waves to food products.
