No matter how sticky, adhesive and viscous the material is, Kenki can dry it without clogging inside of the dryer and with a stable, continuous operation. The special dual-screw constriction guarantees no operational trouble during the drying process. For some types of industrial waste, e.g. pharmaceutical, pasteurization of waste water sludge is a must.
We supply you spare part service for 24 hours a day so you can recover production quickly and timely with the fittings timely supplied by us. The efficient dehumidifier widely used for drying of seafood,which need pay special attention to the control of temperature and humidity in drying.Such as fish drying,sea cucumber drying,seaweed drying,seaweed drying,shrimps drying,etc. The intention of such initiatives is to control and meet overall pollution load targets for a given watershed by trading nutrient reduction credits between point and non-point source dischargers.
EnviroMixbrings innovative mixing & process control technologies to a broad spectrum of municipal and industrial markets. Our progressive cavity pumps, macerators and control systems are used wherever low to highly viscous, aggressive or abrasive media must be conveyed at low pulsation rates – we keep everything flowing. Charter Machine Companystrives to provide all-inclusive service for your dewatering needs. To achieve that goal they offer competitively-priced polymer systems and plant specific, customized conveyors to complement their numerous dewatering units.
The lower section of the basket serves as a predewatering zone, where free water drains by gravity. Here the sludge is compressed between narrowing flights of the screw (or progressively enlarging flights of the screw, as shown in Figure 3.28). The pressure in the pressure zone is controlled by the position of a cone at the discharge end of the basket.
The Aquastore tank is considered the premier tank in the liquid storage industry. As the glass-fused-to-steel technology on both the tank interior and exterior is impermeable to chemicals, the tanks are ideal for any application from potable water to landfill leachate and more. Whether you’re looking for a single product solution or complete Bio-Solids upgrade, we can assist in energy savings and lowering disposal costs. Taida new type air swept dryer can greatly save floor occupied, which provides great convenience for customers who has land limits.
Since more than 50 years company specialises in development of industrial sludge dryers, feeding and sorting equipment as well as other environmental protection machines used in Japan and worldwide. During the time, Kenki has expanded it’s specialisation in the unique twin screw drying technologies, developing several generations of sludge dryers for sticky and pastry materials. Today, the core focus of the company is development and providing the newest generation continuous drying equipment – Kenki SHTS. Heat pump low temperature sludge drying equipment adopts automatic control heat pump drying &dehumidification technology. The difference between heat pump drying and traditional hot air drying is that air circulation and air dehumidification are different. When heat pump dry, the air is closed in the drying chamber and the heat pump drying unit, and the cooling system of the heat pump unit is used to cool and humidify the hot and humid air from the drying chamber.
The best part of buying these efficient vacuum sludge drying machine is the after-sales service that involves maintenance and other associated activities. Since KENKI DRYER has a very simple construction, the initial cost is low and is estimated to be repaid with the cost of industrial waste disposal for about 2 -3 years. Since the quantity of replacement parts is small, maintenance is easy and maintenance cost is very low. In the drying process of KENKI DRYER certificated as International Patent, the material to be dried are moved forward into the dryer’s main body smoothly by being heated and crashed with a feeder at the inlet.
During thermal sludge drying almost all water is evaporated, including surface, capillary and cell water. Supply of heat is needed, preferably from combined power and heat generation systems. A great portion of the drying heat is recovered from the exhaust and re-circulated. Solids contents in the dried product of 90% DS and above can be achieved. Innovative high qualitative machines, plants and stainless steel equipment for municipal and industrial water, wastewater and sludge treatment. The refrigeration system is used to cool and dehumidify the humid air from the drying room, and at the same time recover the latent heat of moisture condensation to reheat the dry air.
A mechanically fixed connecting rod ensures that the required exhaust gas path is free or closed, as applicable. While the valve closes in one direction, the other vale opens at the same time. Irrespective of the drying process, the CHP continues to function unhindered. This means that if the control signal fails, the power cuts out or there is a sudden drop in pressure, the exhaust gas path to the dryer will be immediately closed by means of a mechanical or battery-operated spring reset. The exhaust gases are discharged via the exhaust gas pipe of the CHP. After the material is crushed, the contact area with the hot air is increased, so that the hot air can be fully utilized, and the exhaust hot air is recycled, which greatly reduces energy consumption.
AS-H plate presses are well suited for dewatering of smaller batches where very high dry cake solids (up to 40%) and solids capture over 99% is required. The main organic pollutants in sludge are benzene, chlorophenol, polychlorobiphenyl , polychlorodibenzofuran and polychlorodibenzodioxin (PCDD/F). The organic pollutants contained in sludge are not easy to degrade and the toxic residues are long. These toxic and harmful substances will cause environmental pollution when they enter water and soil.

Compared with ordinary sludge dryers, it can save nearly 20% of coal consumption and save costs for customers. The combined sludge turning and transporting system is at the heart of the drying plant. The sludge is transported through the hall virtually continuously or as an option in batches. With its double shovel the turning/transporting unit can not only aerate, break up and move the sludge through continuous shovelling but also achieve a controlled distribution of sludge in its shovels.
To remove the residues, the beds are first taken out of service for 6 months. This allows the uppermost layer to become mineralized and disinfected. When the solids are removed for disposal, the top gravel and sand layers are also removed and must be replaced. The use of reed beds is practical for wastewater treatment plants of capacities of less than 0.2 m3/s . Screw Presses A screw press is a dewatering device that employs a dewater-ing and conveying screw inside a screen. Figure 3.28 shows two types of screw presses, one with an inclined screw arrangement, the other with a horizontal installation with the added steam feed capability for additional drying of the cake.
Control processing temperature under 75ºC with outlet dried sludge temperature below 50ºC. The frame construction is produced in a modular design of strong-walled stainless steel profiles. All elements within the drying chambers that come into contact with the material are designed in stainless steel. All the interior cladding of the dryer rooms is non-corrosive material. The external cladding of the dryer is produced from stainless steel profiles with 60mm of mineral wool insulation.
