日本乾燥機 List of Products and Services

The jacket rotary dryer is a drying machine developed to reduce exhaust treatment, increase thermal efficiency, facilitate operational control, and purify the working environment compared to conventional rotary dryers. The material to be dried, supplied by a screw conveyor, is subjected to lifting and stirring actions within the rotor, ensuring sufficient contact with the jacket and heating pipes to heat and advance the drying process, moving through the interior of the rotor along the slope of the dryer and being discharged. The evaporated paper is expelled outside using air or inert gas as a carrier gas and directed to an exhaust treatment device. 【Features】 ■ Low-temperature drying is possible using low-pressure steam, hot water, etc. ■ Easy waste treatment due to low exhaust volume ■ Easy operational control ■ High thermal efficiency (70% to 90%) ■ Cooling operation is also possible *For more details, please contact us or download the catalog.

A fluidized dryer is a type of dryer that sends hot air from the bottom to the dried material on a perforated plate, fluidizing the material so that it floats in the hot air, which significantly increases the heat transfer rate. The dried material is suitable for powders, and since the contact state with the hot air is good, there is no temperature difference in the dried material, allowing for uniform drying. The amount of hot air is set based on the relationship between the size and density of the dried material and the terminal velocity and minimum fluidization velocity, so it is necessary for the dried material to be of a certain size. 【Features】 ■ High heat capacity coefficient ■ Easy adjustment of residence time ■ Short drying or cooling time ■ Few moving parts, making maintenance simple ■ Compact device capable of large-scale processing *For more details, please contact us or download the catalog.

The ventilated rotary dryer consists of a rotating body (such as wire mesh, perforated plates, and louvers) and a hot air and exhaust system. Drying is achieved by uniformly passing hot air through the material layer inside the body, while the gentle incline and rotation of the body stir and mix the materials as they move and dry. By installing hot air systems for each block, it is possible to arbitrarily set the temperature, humidity, and air volume according to the progress of the drying process. Additionally, drying and cooling can be performed in the same process. 【Features】 ■ Sturdy construction, simple mechanism, and easy handling and maintenance ■ Temperature, humidity, and air volume can be freely adjusted according to the progress of drying ■ Since hot air passes through the material layer, a large filling volume can be accommodated, making the device compact and ideal for mass production *For more details, please contact us or download the catalog.

This method involves loading the dried material onto a conveyor made of a net or perforated plate, where it receives hot air while moving. There are two types of airflow methods: passing airflow and horizontal airflow. Generally, the passing airflow method is used, where hot air is forced to pass through the gaps of the dried material from top to bottom, making it an efficient method. It is an ideal dryer for materials that may lose shape due to impact, as it is a stationary type. While it has less drying unevenness, it can achieve even more optimal drying due to its multi-stage design and the ability to reverse the blowing direction. 【Features】 ■ High drying capacity and potential for compact equipment ■ Drying conditions (temperature, humidity, wind speed) can be set for each chamber according to the physical properties of the dried material ■ Minimal damage to dried materials and dust generation due to its stationary design ■ Consistent processing of raw materials such as press cakes is possible with the installation of a forming machine ■ Good thermal efficiency allows for a reduction in the necessary energy *For more details, please contact us or download the catalog.

The "forming dryer" is a drying machine where molding and preliminary drying occur simultaneously. Numerous grooves, 5 to 10 mm wide and a few mm deep, are cut in the circumferential direction of the drum, and these two drums rotate in a way that they interlock to facilitate drying. Moreover, by passing a heating source such as steam through the inside of the drum, the material to be dried is pressed into each groove, and the temperature rapidly rises due to the thermal conduction of the groove surface. Additionally, by arbitrarily changing the interlocking of the drums, it is also possible to adjust the final moisture content. 【Features】 ■ Continuous drying is possible by molding press cakes and slurry-like materials. ■ Air-permeable drying significantly improves capacity, leading to uniform drying and enhanced quality. ■ Significant labor savings are achievable. *For more details, please contact us or download the catalog.

The vacuum vibration dryer fluidizes bulk materials through vibration and dries them by contact with the heat transfer surface of the jacket structure. The amplitude is up to 3mm. There are no stirring blades or other devices inside, so contamination does not occur, and the cleaning capability is excellent. There is a horizontal type suitable for large capacities and a vertical type suitable for small quantities and various products. By using an air spring system for the springs, it is possible to create a downward slope during discharge, thereby reducing the discharge time.

Box-type dryers are classified into horizontal and ventilation types based on the method of hot air inflow. The horizontal type involves loading trays filled with the material to be dried and passing hot air horizontally through them. The ventilation type involves filling trays with a net or perforated plate at the bottom and passing hot air through the material being dried. This method is suitable for batch processing and relatively small lots, accommodating various types of dried materials. There are cart-type dryers, where shelves loaded with trays are inserted and removed using a cart, and shelf-type dryers, where shelves are installed inside the unit.

The vacuum shelf dryer is a device that has a heating plate inside, on which containers filled with the material to be dried are placed. It operates by reducing the pressure inside the chamber and allowing the material to sit in a static state, using conduction heating from below and radiation from above to carry out the drying process. Exhaust is discharged outside by a vacuum pump. It is ideal for drying materials with low product tolerance temperatures due to the ease of drying under high vacuum conditions.

A drum dryer is a drying method that supplies steam or hot water to a cylindrical drum, allowing slurry or liquid dried material to adhere to the surface in a film-like manner, which is then scraped off with a scraper. It can dry from liquid to solid in a short time. It can also be used as a flaker by supplying refrigerant inside the drum to cool and solidify the slurry or liquid. There are types with a sealed casing that allow for reduced pressure. The drum can be a single drum or a double drum, selected based on the dried material. It allows for continuous unmanned operation and is mechanically easy to maintain. Dried products can be obtained directly from slurry or solutions.

The rotary crusher dryer is a rotating agitation dryer that blows high-temperature hot air into a cylindrical body, crushing while granulating and drying through an internal stirring mechanism and a lifting flight. Depending on the material properties and the desired finish, there are two methods for supplying hot air: a co-current method that blows air from the supply side and a counter-current method that blows air from the discharge side.

The vacuum mixing dryer is a sealed cylindrical device that supplies the material to be dried into the canister, allowing the heat transfer medium to flow through the jacket, mixing blades, and shaft, while drying through mixing, stirring, and crushing. The optimal mixing blades are designed based on the physical properties of the dried material to enhance drying efficiency. Dust contained in the exhaust is collected by the built-in bag filter, and solvents are recovered using an external condenser.

The double conical blender dryer allows for the introduction of dried materials into a double cone-shaped body, where drying occurs through contact with a heat transfer surface due to its jacket structure. Since the contact state between the dried materials and the heat transfer surface is constantly updated, the finished product has minimal unevenness. An automatic feeding and discharging mechanism option is also available.

Drying, cooling, and sieving can be performed with the same machine. It is also used as an agglomeration and granulation device. The vibrating fluidized dryer is a drying method that fluidizes the material using mechanical vibrations and hot air. Compared to methods that fluidize only with hot air, it reduces the amount of air and power required, thereby lessening the exhaust treatment load. The fluidization air velocity is lower than that of a fluidized dryer, and the collection device is also more compact.
