Increase efficiency and ensure product quality with innovative weighing and inspection solutions Vegetable meat alternatives continue to be in vogue
Meat consumption patterns have changed significantly in recent years. In Germany, for example, 44 percent now eat a flexitarian diet, i.e. eat meat only occasionally, seven percent vegetarian and one percent vegan (BMEL Nutrition Report 2022). Animal welfare, environmental protection and health are the reasons for giving up meat. The global market for plant-based meat alternatives is already worth billions and is growing at double-digit rates. Due to this development, many companies are already fighting for market share. Start-ups and traditional meat producers are competing with consumer goods multinationals like Nestlé and Unilever. Many companies are making targeted investments in their production facilities to keep up with the high demand. However, the current challenges such as supply bottlenecks and increased energy costs are not leaving these companies unscathed. Maximum efficiency and the greatest possible conservation of resources along the entire value chain from production to packaging are more important today than ever before.
Find out in this article which advantages meat substitute producers can draw from the latest weighing and inspection technologies from Minebea Intec.
As in the entire food industry, hygiene and product quality are of crucial importance in the production of plant-based meat alternatives. Contamination or foreign bodies in the vegetarian or vegan foods and the associated product recalls can not only be expensive and damage trust in the brand and the company, but above all endanger the health of consumers. At the same time, cost savings, sustainability and high throughput are important issues in the industry.
Requirements for the production of vegetarian and vegan meat alternatives
In order to come as close as possible to the traditional schnitzel, steak or burger in terms of shape, consistency, taste, smell and mouthfeel, the highest quality standards are required in production. The recipes often consist of more than 30 individual components - be it different flavourings or fibre structures of fruit seeds, pulses or vegetable peelings. To bring the ingredients together in the right proportions, companies work with automated mixing systems equipped with high-precision load cells from Minebea Intec. "Our weighing solutions guarantee accurate, continuous, fast and flexible dosing processes and minimise material losses," says Yannick Salzmann, Global Product Manager at Minebea Intec. The weighing solutions can be easily integrated into the production lines of manufacturing companies as an OEM solution. "Our Novego® weighing module was developed specifically for tank and process vessel weighing in the food and pharmaceutical industries," says Yannick Salzmann. "The hygienic all-in-one solution offers a variety of innovative features for easy, error-free installation as well as maximum resistance to lateral forces." The Novego® weighing module ensures process reliability, measurement accuracy and fast cleaning processes. The exceptional corrosion resistance of the stainless steel as well as the product design oriented towards the guidelines of the EHEDG make the weighing module insensitive to dirt, water and even aggressive cleaning agents.
Increase precision and process speed with dynamic checkweighers
When the mixing process is complete and the products are on the conveyor belts, Minebea Intec's dynamic checkweighers come into play. "With the help of dynamic checkweighers, companies can optimise their production processes, improve material and resource management and increase the accuracy and consistency of production processes," says Lars-Henrik Bierwirth, Product Manager at Minebea Intec. "Our Flexus® checkweigher is the ideal solution for the highest product quality - regardless of whether customers want to check product weight or completeness or optimise their filling and sorting processes." High-resolution EMFR load cell technology and a customised design guarantee precise weighing results and high throughputs of up to 600 pieces per minute. The Flexus® checkweigher integrates effortlessly into existing production environments. Changing line configurations and rapid product changes are handled quickly and easily. Optional stainless steel tables make the Flexus® checkweigher easy and safe to clean.
Metal detector Mitus® reduces false rejects and ensures highest product quality
In addition to checkweighing, foreign object inspection plays an important role in the meat substitute industry. The new metal detector Mitus® with the innovative MiWave technology enables highly precise detection of metallic foreign bodies even with the largest product effects, which can occur frequently, especially with meat-type products. With MiWave, a multitude of frequencies are modulated onto the transmitted signal, which are then separated and evaluated separately by an intelligent algorithm. With the help of this separation, the products can be inspected symbolically from several perspectives. Due to this significantly increased information content, high search sensitivities can be achieved despite large product effects. The result for producers: maximum product safety and maximum output.
The Mitus® metal detector is available in standard sizes as a rectangular, round or compact detection coil as well as a free-fall and pipeline application, so that it can be integrated into production facilities even where space is limited and depending on requirements. The Mitus® metal detector can also be easily combined with additional weighing technology if required. "With the Mitus® , we offer users a premium solution for metal detection," says Linus Dellweg, Global Product Manager at Minebea Intec. "Meat substitute producers can thereby rely on our premium quality 'Made in Germany'."
Carefree with safety: Dypipe X-ray inspection system with innovative validation system
As plant-based meat alternatives are made from a variety of ingredients, unwanted parts such as shell remnants may end up in the products during raw material preparation. To identify these tiny foreign bodies and remove the contaminated products, many companies rely on Minebea Intec's X-ray inspection systems. Minebea Intec offers a complete portfolio of X-ray systems for the inspection of packaged products. Typical applications include cartons, boxes, bags, pouches, trays and portion packs, which can contain a wide variety of dry or liquid food products. The Dylight and Dymond models have been specially developed for these applications. They feature a hygienic design in accordance with EHEDG principles and high detection sensitivities with low power consumption.
For viscous and liquid products such as vegan mince, Minebea Intec has recently launched the Dypipe X-ray inspection system. The Dypipe is equipped with an innovative specimen insertion system that enables specimen verification in live operation. This means that producers can always be sure that their production processes are working properly and do not lose any time for inspection when the plant is at a standstill. For the high hygienic requirements in meat substitute applications, the Dypipe is equipped with an easy-to-open separator that has been specially developed for this purpose. This system guarantees excellent results and gives the security of producing high quality food.
