Kenki dryer.

Kenki: sludge dryer for humid and pastry products

Our company is authorised European distributor of Japan based Kenki Corporation, company specialised in drying equipment in Europe.

Kenki dryer bases on the unique design of self-cleaning double screw conveyors that guarantees the effective process of moving the feedstock. The dryer is specially designed for continuous drying of pasty and sticky materials.

How our sludge dryer works?

Our sludge dryer is based on synchronized twin screw conveyors are carrying the material through the dryer’s chamber and preventing sticking of the material to the hot surfaces of the dryer. Special design of blades that are turning in the intersection with each other enables to dry and agitate the material. Adjacent blades are scraping off the material that deposits on the primary blades. Solid waste is crushed and dried simultaneously inside the dryer.

    Applications of Kenki dryer:

  • chemical sludge
  • industrial sludge
  • hazardous sludge
  • municipal sludge
  • food waste
  • other high moisture and viscosity materials

    Features of Kenki dryer:

  • high efficiency
  • low drying temperature
  • compact construction
  • no drying air installation required
  • simple and effective vapour condensation
  • high-moisture and pastry materials processing

About Kenki Corporation

KENKI Corporation has been established in January 1964 in Fukuoka, Japan, as a company specialised in developing, design and manufacturing of maintenance and industrial equipment. 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.

No matter how sticky, adhesive and viscous the material is, KENKI DRYER of International Patent can dry it without clogging inside of the dryer and with a stable operation that no operational trouble occurs because of its unique mechanism.

Sludge after dehydration process of wastewater treatment is often affected by flocculants and forms large lumps, and it frequently happens that only surface is dried but inside are not when sludge is discharged as large lumps.

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. The materials get smaller and smaller since they are continuously sheared and agitated during being conveyed and heated. As the material gets small, heat reaches inside more smoothly and surely, and quality of outputs becomes stable.

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. Also, as the heat source of drying is only saturated steam, an epochal mechanism based on combined use of conductive heat transfer method and heated air method helps to achieve a high quality of safety and hygiene, and running cost can be kept low by using surplus steam within your facility. Machine operation is conducted in continuous mode easily and there is no need for supplementary operators and labor. Since the quantity of replacement parts is small, maintenance is easy and maintenance cost is very low.

Because of low-temperature drying, the composition of the dried material is not affected and organic sludge can be sold as fuel, fertilizer, etc. after being dried. Because the low-temperature drying does not use flame, the temperature of the dryer’s outer surface is low and the dryer is safe and hygienic. Because fresh air from outside is kept off, the temperature inside of the dryer is kept high, amount of moisture in the exhaust air discharging water is small, and the discharged water can be returned to wastewater treatment facilities.

Patented: 2 domestic Japanese patents, 2 overseas countries / Patent applied for 5 overseas countries, 1 state. (as of 10th April. 2018)
