Indirect Heating Type Vertical Dryer

Indirect Heating Type Vertical DryerIndirect 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.

Processable items

  • Food residues (supermarkets, restaurants, etc.)
  • Food factory waste (tea, coffee, red beans, okara, fruit, etc.)
  • General kitchen waste
  • Pulp cake
  • Activated sludge, manure sludge, sewage sludge
  • Fishery processing sludge, inorganic sludge, etc.

Sanyu’s dryers use an indirect heating method to prevent the change in quality of processed materials.

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.
