The latter works by injecting sound waves at a frequency of 38.8 kHz at multiple points through its walls, generating multiple regions for acoustic cavitation within the reactor.<\/p>\n<div class=\"aawp\">\n<div class=\"aawp-product aawp-product--horizontal aawp-product--ribbon aawp-product--sale\" data-aawp-product-asin=\"B0B9YP76FN\" data-aawp-product-id=\"121197\" data-aawp-tracking-id=\"tec02e-20\" data-aawp-product-title=\"Ninja CFN601 Espresso &amp; Coffee Barista System 3 Espresso Brew Styles Single-Serve Coffee &amp; Nespresso Capsule Compatible 12-Cup Carafe Built-in Frother Espresso Cappuccino &amp; Latte Maker - Black\">\n<p>    <span class=\"aawp-product__ribbon aawp-product__ribbon--sale\">Sale<\/span><\/p>\n<div class=\"aawp-product__thumb\">\n<p>            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41zQAjlBuFL._SL160_.jpg\" alt=\"Ninja CFN601 Espresso &amp; Coffee Barista System, 3 Espresso Brew Styles, Single-Serve Coffee &amp; Nespresso...\"\/><\/p><\/div>\n<div class=\"aawp-product__content\">\n<p>            Ninja CFN601 Espresso &amp; Coffee Barista System, 3 Espresso Brew Styles, Single-Serve Coffee &amp; Nespresso&#8230;        <\/p>\n<div class=\"aawp-product__description\">\n<ul>\n<li>BARISTA PLUS TECHNOLOGY: The 19-bar pressure system delivers ultra-flavorful espresso with a silky-smooth crema by brewing at the optimal temperature&#8230;<\/li>\n<li>COFFEEHOUSE DRINKS AT HOME: The built-in, fold-away frother allows you to create espresso-based cappuccinos, lattes, flat whites, and more.<\/li>\n<li>BREW SINGLE-SERVE ESPRESSO: Choose your favorite espresso capsule and brew up to 3 styles: Espresso (1.35 oz), Lungo (3.75 oz), and Over Ice (1 oz).<\/li>\n<\/ul><\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n<p>\n<img decoding=\"async\" src=\"https:\/\/images.techeblog.com\/wp-content\/uploads\/2024\/05\/09190834\/ultrasonic-coffee-machine-cold-brew-2.jpg\" alt=\"Ultrasonic Coffee Machine Cold Brew\" width=\"1280\" height=\"853\"\/><\/p>\n<blockquote>\n<p>Ultrasounds accelerate the extraction process due to acoustic cavitation.
