Choosing the proper industrial machinery has consequences that touch on every aspect of your business, including how much you produce, the money you save on labor, and the quality of your goods. In food processing, a chip cutter plays a major role in determining your end product's quality. In food processing, a chip cutter is much more than a simple blade; It helps you control the final product's texture, yield, and even visual attractiveness. After working in food machinery manufacturing and assisting hundreds of international clients optimize their processing line, I have seen how a poor decision leads to more waste and how a good decision positively impacts a business' return on investment.
When selecting a chip cutter, the first step is honest evaluation of volumes and expectations of future increases. Requirements for small boutique processors are nowhere near those of large-scale industrial plants. In my experience, most businesses do not consider the space and weight of a future expansion. Underpowered machines become operational bottlenecks, and result in poor process control and quality. Look for operational rating of volume processed per a specified time, for example, the mid to high range of industrial machines is designed to process between 500 to 1,000 kg of product per hour. Furthermore, selecting a modular unit design ensures that your future expansion and customer growth investment will not be wasted on replacing a complete module.
A good chip cutter needs to be made well. While processing potatoes, sweet potatoes, taro, or carrots, the material and the design of the blade are very important. Expert design says that blades should be made of food-grade 304 stainless steel for optimum durability and safety. From a technical perspective, the sharpness and angle of the blade determines the amount of “bruise” damage done to the vegetable. A blade that is dull or poorly designed will “tear” the fibers of the vegetable and cause the cores to lose water and starch, and, as a result, the crunch of the vegetable will be lost after frying. Look for machines that have blade sets that can be changed. Being able to switch a blade to change between flat slices, crinkles, and strips (french fry blades) will keep the downtime minimal. This will allow you to cater to the demand of the market and change the products that you are making without the need to buy more machines.
In the contemporary food processing sector, hygiene is the foundation of "Trust." A chip cutter that is tough to clean represents the greatest risk. In compliance with global food safety regulations (CE, FDA, etc.), food processing equipment must be designed to be "wash-down" compliant. That is, the motors and electricals need to be properly sealed (IP65 or greater) so that the entire equipment can be cleaned with high-pressure water. We practice "no-tools" design in our factory. This means that, within a few minutes, operators can fully remove the cutting head and conveyor belts to perform deep cleanings. Maintenance simplicity is a fundamental aspect of food safety and, as a result, it helps to effectively reduce the "Total Cost of Ownership" by eliminating the risk of costly bacterial infections and mechanical failures.
The “expertise” of the manufacturer usually lies in the motor and drive system. For industrial chip cutters, the motor should be a copper-core motor, as an aluminum-core motor is likely to overheat and burn out during an 8-hour shift. Also, try to look for machines that have Variable Frequency Drives (VFD). A VFD lets you adjust the speed of the cutting disk, which is important because different vegetables have different levels of density. For example, a sweet potato has a higher density than an average potato, so it requires a different amount of torque to cut. With the right motor speed, you can reduce energy consumption up to 20% and also increase the lifespan of the machine's components.
The level of authority in the world of machinery design can be gauged by the degree of human protection offered by the equipment. Risks are unavoidable at the very basic level of functionalities in equipment for industrial applications. For example, a professional-grade chip cutter should be designed with magnetic safety sensors, and have emergency cut-off buttons. When a guard is opened, the machine should automatically disconnect power. We have contacts in safety inspection who believe that the design of the feeding chute should be such that it prevents a human hand from reaching the blades. When selecting a supplier, be sure to ask for their safety certification and interlock systems with the machine. If a manufacturer represents a decreased likelihood of workplace accidents, that is a good thing because it means an increase in workplace productivity and a manufacturer that is good at their job.
Chip cutters aim to maximize raw ingredient yield. Current best practice in achieving cut-precision is advanced centrifugal cutting technology. This technology utilises centrifugal force to press the cut vegetable against the wall of the cutting drum. This ensures that each slice is the same thickness. Slice uniformity is about more than aesthetics; It also affects cooking. Slices of differing thickness will result in some being burned and others being undercooked in the fryer. Achieving a 98% uniformity rate means ‘fines’ or small waste pieces are greatly reduced and your profit margin per raw ton of produce is maximized.
It doesn't matter how good your chip cutter is, it will need replacement blades or belts at some point. After an order is placed, the “trust” of your partner is at stake. Before placing an order, check how well stocked the manufacturer is on wearing parts. In the B2B segment, a food processor losing a blade due to a three week wait for an overseas shipment is a catastrophe. We advise customers to go for suppliers who provide responsive tech support and videos for step-by-step instructions on how to adjust settings. Experience shows that a more expensive machine with good service is much better than a cheap machine with no service at all.
