Indirect Heating Type Vertical Dryer

Indirect heating by steam is safe and can be installed in a small space.

It efficiently reduces the volume of food waste and sludge generated in various places such as food factories, other manufacturing plants, medical facilities, hotels, and the construction industry in a short time, and produces recyclable raw materials such as fertilizer and feed. The indirect steam heating system is safe and can be operated continuously 24 hours a day in batch mode.

Features

High efficiency

It is possible to dry and recycle materials that were previously considered difficult to dry.
（e.g. bean sprouts, udon noodles, rice, poteto, oily food residue, etc.）
Low cost

Indirect heating and agitation by rotating blades prevent the contents from changing, shorten the drying time, and save energy.

・Drying time: 20 to 50 minutes （batch）
・Fuel cost: Heavy oil equivalent 0.03（USD）/1 kg process
・Electricity cost: 0.005 to 0.01（USD）/ 1 kg process

Comparing the total amount of waste disposal cost and initial and running cost, it can be redeemed in 2 to 5 years （depending on material properties）.
Compact and space-saving

This is a simple and compact facility as it performs grinding and drying at the same time in the main body of the dryer. Continuous batch operation allows for 24 hours of continuous operation.
Excellent safety

Indirect heating by steam eliminates the risk of fire and allows 24-hour operation. The negative pressure sealing system prevents dust and odor from escaping.
- ※We also have a system that can make effective use of waste heat from cogeneration.

Structure

High speed agitation provides high drying performance, and even materials that tend to form lumps during the drying process can be granulated to reduce processing time. We offer a wide range of specifications from standard to custom-made according to your processing materials and processing volume. In addition to the main unit of the dryer, we are able to offer a full range of services from receiving to shipping.
