Cutting Sandwiches and Wraps
UFM3100S Ultrasonic Sandwich Cutting System – Precision, Hygiene, and Efficiency
The UFM3100S ultrasonic sandwich cutting system represents a significant leap forward in the automated processing of sandwiches, wraps, and other stuffed bakery products. Engineered for high‑volume food production environments, this state‑of‑the‑art machine combines advanced ultrasonic technology with intelligent material handling to deliver consistently perfect cuts, while simultaneously addressing the industry’s most stringent demands for hygiene and operational simplicity.
At the heart of the system lies a robust, continuous conveyor belt that serves as the primary transport mechanism. Products are placed onto the infeed section of the belt, where an integrated alignment system automatically corrects their orientation. This ensures that every sandwich or wrap enters the cutting zone in a perfectly straight and centered position, regardless of slight variations in the manual loading process. The alignment mechanism uses gentle side‑guides and adjustable sensors that adapt to different product dimensions, eliminating the need for time‑consuming manual repositioning. Once aligned, the conveyor carries the products smoothly through the cutting area at a precisely controlled speed, which can be synchronised with upstream or downstream packaging lines for seamless integration into existing production workflows.
The cutting action itself is powered by ultrasonic technology—a method that sets the UFM3100S apart from conventional blade or guillotine cutters. Instead of relying solely on mechanical force, the system generates high‑frequency vibrations (typically in the 20–40 kHz range) that are transmitted to a specially designed cutting tool. These micro‑oscillations cause the blade to “saw” through the product with minimal compression, effectively reducing the friction and pressure that often crush delicate fillings or deform soft bread. The result is a clean, sharp cut with perfectly defined edges, whether the product contains layered meats, cheeses, fresh vegetables, or viscous spreads. For stuffed wraps, the ultrasonic action prevents the filling from being squeezed out, preserving both the visual appeal and the structural integrity of each portion. This precision not only enhances the final product’s presentation but also reduces waste, as off‑cuts and crumb generation are kept to an absolute minimum.
After passing through the cutting zone, the individual portions are carried forward on the conveyor to the discharge end, where they can be easily picked off by operators or directed to a subsequent packaging station. The continuous, linear flow of the machine allows for throughput rates that comfortably meet the demands of medium to large‑scale food manufacturers, while the adjustable cutting speed and portion size settings provide flexibility to accommodate a wide variety of product recipes and portioning requirements.
A cornerstone of the UFM3100S’s design philosophy is its uncompromising commitment to food safety and sanitation. The entire machine structure has been constructed with hygiene as the primary consideration. All surfaces that come into contact with food products are fabricated from high‑grade stainless steel and food‑grade polymers, which are corrosion‑resistant, non‑porous, and easily sanitised. The frame is engineered with smooth, rounded contours and minimal crevices, eliminating the hard‑to‑clean corners where bacteria or residue might otherwise accumulate. Furthermore, the conveyor belt is made from a seamless, durable material that resists absorption of moisture and fats, and it can be quickly released for cleaning or replacement if needed.
Cleaning the UFM3100S is remarkably straightforward and can be accomplished within a few minutes—a critical advantage in busy production environments where downtime directly impacts profitability. The system features a tool‑less design for most removable components; the cutting tool, guides, and belt tensioners can be disassembled without the need for specialist tools, allowing operators to access all internal areas with ease. A standard cleaning routine involves a simple water‑based washdown using mild detergents, followed by a sanitising rinse. Because the electrical and electronic control units are fully sealed and located in protected enclosures, the machine can withstand high‑pressure spray cleaning without risk of damage. This rapid cleaning capability not only ensures compliance with the most rigorous food safety standards (such as those required by BRC, IFS, or FDA regulations) but also enables quick changeovers between different product types, minimising flavour cross‑contamination and maximising overall equipment effectiveness.
Beyond its core cutting and cleaning functions, the UFM3100S is equipped with an intuitive touch‑screen control interface that stores multiple cutting recipes, monitors blade wear, and alerts operators to maintenance schedules. This smart functionality reduces the reliance on highly skilled personnel and ensures that every production run achieves the same high‑quality output, batch after batch.
In summary, the UFM3100S ultrasonic sandwich cutting system is far more than a simple conveyor‑based cutter. It is a complete, hygienic, and intelligent solution that addresses the real‑world challenges of modern food processing: delivering perfect portion quality, minimising waste, simplifying sanitation, and maintaining high throughput—all while being cleanable in just a few minutes. Whether used for crusty artisanal sandwiches, soft brioche burgers, or multi‑layered tortilla wraps, the UFM3100S consistently outperforms traditional cutting methods, making it an indispensable asset for any forward‑looking food production facility.
About Cheersonic
Cheersonic manufactures the leading portioning equipment for bakeries producing fresh and frozen desserts. Since 1998 bakers have used Cheersonic machines to cut, slice and portion cheesecake, pie, layer cake, loaves, butter, cheese, pizza, sandwichs, and more. Cheersonic offers ultrasonic cutting solutions that support start-up bakeries and high production commercial facilities alike. Small standalone machines can be used in manual baking facilities and large inline robotic solutions aid in high speed production.
Cheersonic offers many ultrasonic slicing models, both inline and offline applications, with production speeds of 80 to 1,500 cakes or pies per hour.
Cheersonic’ latest offline introductions include ultrasonic cutting with or without divider inserts between each slice. This improves the quality of the cut and makes for a much better product presentation for the customer. In addition, robotic arm improves the speed, efficiency, and accuracy of the cutting process, producing professional looking products every time.
