Insect larvae - smoothly separated with new processes

While others are just screening, we are seeing the big picture. Since its foundation RHEWUM has always been looking for the perfect solution. As the leading company in the field of industrial sieving technology we do not just provide screening machines, but the optimal separation of bulk materials that is perfectly tailored to your needs. We can achieve this through customized technology that offers unrivaled reliability with the highest service and product quality.

Insects such as buffalo worms and mealworms are a sought-after source of protein as sustainable feed as well as for a climate-friendly diet. RHEWUM has the technology for gentle sieving of live larvae on an industrial scale. Like many other insects, buffalo and mealworms are a high-quality source of animal protein. Buffalo worms are the larvae of the glossy grain mould beetle and grow to about 7 to 11 millimetres in length [1]. Worm, or not Flourworms are the larvae of the flour beetle and grow considerably larger than buffalo worms, reaching up to 40 millimetres. Both are larvae of the black beetle family and are not worms in the true sense, as they each have three pairs of legs. Nevertheless, for the sake of simplicity, the buffalo and mealworms are referred to here synonymously as larvae and worms. Climate-friendly proteins Compared to other farm animals, the breeding and keeping of buffalo and mealworms is much more climate-friendly, which means that worms are becoming increasingly important as a component of a sustainable diet. For each kilogram of edible protein from insect larvae, a similar amount of energy is required as for each kilogram of protein from milk, chicken,

Calcium carbonate is a material that originated from the remains of single-celled sea creatures over millions of years of Earth’s history. Today, it is the basis for a range of commonly used building materials, including limestone and dolomite. Finest separations up to 0.1 mm A British customer discussed with RHEWUM ways to renew an aging installation for processing calcium carbonate. Several existing sieving machines and sifters were to be replaced. Fine separations up to 0.1 mm were performed. Setting vibration during operation Machines with direct excitation of the screen fabrics were planned as the machine type. Drives for the decks on which coarser separations were to be performed were unbalanced motors. The decks for fine separations were equipped with oscillating heads that allow the vibration to be changed during operation via thyristor controllers. The machine types of choice were then RHEsono, RHEmoto and RHEfino as a combination of both types. For the task of feeding the material onto the machines, RHEside feeders with lateral feeding were used. Customer requirements were met With

Sodium carbonate is difficult to screen as its hydrophilic properties cause agglomerations. RHEWUM’s high quality sieving technology increases production. Soda ash is obtained from sustainable production sources, such as the processing of wood. Soda ash is an indispensable raw material in partticular for the glass industry, but also used as a bleaching agent in the chemical industry and not least in the lye of Bavarian pretzels. The demand for high-quality soda ash is high. The quality of the soda granulate is significantly influenced by the performance, and thus the quality, of the screening machine in use. Soda ash is considered to be a difficult material to sieve, which easily sticks to the screening mesh and tends to form lumps due to its hydrophilic properties. The screening mesh can quickly become clogged and the entire production come to a standstill. Thus, the reliable supply of soda ash for important industrial sectors, and with it the capacity of soda ash producing plants, depends on the screening machine. With the RHEWUM WA, RHEWUM offers a state-of-the-art screening machine with direct excitation of the

In cooperation with biologists, Rhewum has developed a new screening machine for sorting mealworms. Screening mealworms poses unique technical challenges with regard to animal health and safety. Rhewum joins the Food Revolution, with a newly gentle sieving developed method for use in large mealworm farms In cooperation with biologists, Rhewum has developed a new screening machine for sorting mealworms. Mealworms are gaining importance in the food industry as a sustainable source of high quality protein, and screening them in an animal friendly way poses unique technical challenges. Top quality protein Mealworms have long been regarded as unwanted additions by the food industry, but they have enormous potential for making our future more sustainable. Mealworms may not look like much, but they contain top quality protein and unlike other animals raised for meat, their impact on the environment is much less and they have few requirements for a healthy existence in accord with their needs. Increasing demand for sustainable, climate friendly alternatives to conventional animal protein means an increase in the demand for mealworms. Highly specialized sieving Mealworms
