Potash drying in a Tema Process Fluid Bed Dryer
Potash is a potassium-rich water soluble salt. Approximately 95% of potash production is fertilizer used for agricultural purposes. The most common form of potash fertilizer is potassium chloride (KCl) but can also include potassium carbonate (K2CO3), potassium sulfate (K2SO4), or potassium nitrate (KNO3). Potash increases water retention in plants, improves crop yields, and influences the taste, texture, and nutritional value of many plants. After potash [...]
Automatic weirs for controlling the bed height / residence time in Fluid Bed Dryers
Automatic weir(s) for controlling the bed height/ residence time in Fluid Bed Dryers: In an efficiently fluidized bed, the solid material like granules/powders or pellets, are fluidized by an upflow gas. The wet solids are lifted from the bottom and causes the solids to behave as a fluid. The air velocity is adjusted to keep the moving layer of material fluidized. At the end of [...]
Biomass / Wood Fiber Tema Process Fluid Bed Dryer
The raw material that is renewable comes from the forest. The wood fibres are used for insulation panels (new and old houses). This insulation has good properties for energy efficiency, moisture and noise reduction and is contributing to a sustainable society. Wood fibre insulation is recyclable and is a natural product
Pasteurize nuts and seeds with a Tema system
Food safety: Nuts & Seed Pasteurizer. Nuts are processed in an environment where cross contamination of pathogenic micro-organisms such as Salmonella can put consumers at risk. Pasteurization is necessary to prevent nationwide outbreaks and product recalls. For example: In 2007 California passed law that requires food processors to pasteurize almonds. This was due to a string of salmonella outbreaks in the early 2000's. Steam pasteurization [...]
Tema Process has developed a new range of industrial-grade and pharma-grade salt fluid bed dryers
Salt is extremely soluble in water. Sea, ocean water or salt brines are the major sources of the world supply of salt. The recovery of salt from sea/brine water occurs by the evaporation of water and until the salt begins to crystallize. Crystallization occurs when the concentration of a chemical exceeds the solubility in the particular solvent. Brine (salt water) is chemically purified and by [...]
Process combined ethanol stripper / dryer with ethanol recovery
Today pectin is mostly produced from citrus peels (lemons, limes and oranges). After juice extraction, essential oil and dissolved sugars are removed from the peel prior to drying. Prior to pectin extraction with dilute mineral acids, the citrus peel must be dried from the starting level of about 85% moisture, down to 10 to 12% moisture to avoid fermentation. Because of the high water content [...]
Fluid bed dryer for sand drying
Sand drying: a fluid bed dryer processes granular, free-flowing materials include sand, minerals, clays, organic salts, coal, etc. In a fluid bed, the material being dried is suspended and completely surrounded by the drying air or gas, causing that material to behave like a fluid. Besides keeping the material in a seemingly liquid state, the gas stream is the media for heat and mass exchange. [...]
Exhaust air system for fluid bed dryers
The packed tower scrubbers are used to remove particulate and / or vapor contaminants from an exhaust gas stream by way of dilution or absorption. A packed tower is an efficient method of carrying out mass transfer between gas and liquid phases. Packed tower scrubbers incorporate packing media to facilitate intimate contact between a scrubbing liquid and gas to be scrubbed. Applications are: reduction of [...]
Dewatering and drying solution for ABS
ABS is a thermoplastic (Acrylonitrile Butadiene Styrene) and has countless applications. Among the most widely identifiable are keys on a computer keyboard, power tool housing, the plastic face guard on wall sockets and LEGO toys. The ABS drying line mainly consists of a centrifuge, a solid bunker and a two-stage dynamic fluid bed dryer. The rapid heat and mass transfer rates between the product [...]
Dryer: Heat Recovery-Energy Savings
Dryer: Heat Recovery-Energy Savings: Pre-heating the supply air (ambient air) with energy from the exhaust air ! Substantial energy savings have been shown by heat recovery from the Tema fluid bed dryer exhaust air stream (10-25%). The heat exchanger (air-air) and ducting are manufactured in stainless steel AISI304L.
