In the production of plant-based food and drink, a residual flow arises. This can be, for example, fiber residues from the production of oat drinks and soy drinks. These residual flows have a high value and can be used as a wholesome food thanks to the still high nutrient content. However, there are major challenges in being able to achieve food quality. These can be microbial challenges during the decay process starting quickly, the material itself is sticky and difficult to handle, volume changes in the production process, the nutrient content must not be destroyed or changed and the material must not be burned.
Plant Based Food and Beverages
Oat drink
In oat beverage production, a residual flow of wet oat fiber, reOAT, is formed. The fiber contains several nutrients such as protein and fiber. If the material is dried, it can be returned to the food chain before it rots.
Soy drink
In the production of soy drink, the solid part of the soy remains, which is called Okara. Okaran contains a lot of water but also several nutrients and can be used as a valuable raw material if it is taken care of. Okaran can, for example, be used as a vegan meat substitute.
Brewery
Brewer’s spent grain is a by-product of the brewing of beer. The spent grain contains several nutrients, especially protein and fiber. Due to the poor durability of the material, much of it is wasted. If it is dried, the putrefaction process stops and the spent grains can be taken care of and used in food production as an additive or in new food products.
Other beverages
reCirculating Food Dryer can be used to dry several different residues from plant-based foods and beverages. Residues from PBFB production that are dried can be used in new food products or in animal feed products as raw material that are sent for further processing.
Drying is needed in a number of different markets
Dewatering and drying can be applied in a number of different markets. reCriculating Food Dryer is well suited for drying by-products from the manufacture of plant based drinks. reCirculating Food Dryer maintains a high hygienic standard and the dried material can then be used for other food products. Freeze Dry Unit’s unique process for dewatering opens up several areas of use, as well as freezing enables easier drying to high dryness levels thanks to a simpler drying process free of, for example, polymers. The solutions can also be combined for an entire dewatering and drying process.
Aquaculture
Residual products from fish farms are found to a large extent in the form of sludge. This needs to be taken care of in order to be able to reuse and recycle the water.
Biogas
Biogas sludge differs from sewage sludge in that it may contain crops, manure, residues from farms or perhaps slaughter and brewery waste. Sludge from biogas plants can also contain sewage sludge or a mix of different types of sludge.
Plant Based Food and Beverages
In the plant based food and beverage production, residual products are formed and have great opportunities for reuse. Today, it can be a challenge to take advantage of these residual products. In oatdrink production, a residual product of oat fiber is...
Paper pulp
Different sludge fractions that arise in the process of papermaking need to be taken care of. This can be done by dewatering and drying the residual waste.
Nuclear
Radioactive sludge is generated in the nuclear power industry. In the ion exchange mass, among other things, radioactive particles are captured and form a sludge-like waste that needs to be disposed of.
Wastewater treatment
Today, much of the sludge that is generated in municipal wastewater treatment plants is only dewatered to a dry matter content between 20 and 30%. This entails high costs and other problems.
