Extracts Chicken bone, meat, seafood, vitamins, enzyme, yeast
Sugars Liquid that need to prevent coloring, decomposition, or deterioration of oligosaccharides and honey
Milk and others Liquid that need to be concentrated in a short time
Plate type evaporator(LEP: Membrane flow system)

The stock solution, which is pre-heated and entered in the evaporator, is self-evaporated by the temperature difference between the inside of the equipment, instantly heated and evaporated at the plate surface.
The circulation of the considerable capacity liquid increases the speed, and the scale becomes difficult to adhere to the plate surface.

Features

  • Because the mass velocity is high and the distribution of the liquid is uniform, the operatione is difficult to adhere.
  • The heat transfer performance is three to five times higher than conventional multi-tube type.
  • Short processing time, and the liquid contacts with the heat transfer surface about 2 seconds, suitable for heat-sensitive liquid.
  • The circulation system is adopted to cope with changes in the stock solution.
  • Easy to disassemble, easy to wash plates and increase or decrease the number of plates.
  • Fully automated operation from start to cleaning with a single button.
  • Stainless and titanium are available for the plate material.

Applications

Food Milk, soy protein, liquid sugar, sucrose, isomerized sugar, glucose, starch syrup, various soup solutions, fish juice, high-concentration food wastewater
Fermentation Alcohol distillation wastewater, various fermentation wastewaters, various organic acid aqueous solutions
Chemical Caustic soda, glutamate soda, high concentrated industrial drainage

Vacuum belt dryer(SBD)
High quality solution is realized by continuous drying of highly concentrated solutions under vacuum.
See more

The continuous vacuum drying system dries high viscosity liquid that is difficult to process by spray drying type at low temperatures, and producing the highly soluble dried products in a short time.

Drying System

  • In the vacuum tank [1] of the main body, while operating by the cold trap and
    the vacuum pump [2], the vacuum degree below 10Torr is kept.
  • The raw materials in high concentration and high viscosity in the form of the liquid,
    slurry, and paste is uniformly dispersed in thin layer form on the belt [4] which is
    operating by the raw material supply facility and the uniform dispersion nozzle [3].
  • There are three heating plates [5] and cooling plate [6] on the underside of the belt,
    when the material on the belt passes through the heating zone, it dries at a low temp.
    In this case, the thin membrane raw material evaporates violently the internal water
    forms a porous format with a large number of vents in the interior as well as swelling.
  • When being cooled down in the cooling zone and the product temp. drops, it hardens
    and arrives at the end of the belt.
  • At the end, the granules are primary pulverized with the pre-crusher [7], which is
    attached on the top of the vacuum tank, and the main crusher [8] pulverizes them
    again to produce the best soluble porous granules.

Features

1. High quality dried products can be produced in a short time

  • Low temperature drying around 40℃ is ideal for heat-sensitive raw materials, excellent in solubility and restorability.
  • The raw materials are hygienic and prevent oxidation because it is dried and pulverized in a vacuum tank.
  • Less scattering loss of raw materials and products, resulting in dry products of the same amount and same quality as raw materials.

2. High efficiency and economical drying

  • The selection of the drying rate according to the physical properties enables high concentration and high viscosity drying in the form of the liquid, slurry, and paste.
  • Continuous drying is more efficient than batch type.
  • Design considering heat efficiency and drying efficiency, minimizing incidental equipment such as exhaust and drainage to reduce costs.

Continuous immersion concentrator(RES)

After being loaded into the treatment tank, the boiled raw material is immersed.
The seasoning liquid is gradually concentrated under vacuum, and efficiently infiltrated into the raw material, allowing the umami taste to condense.

Features

  • Infiltrating the seasoning liquid into the product in a short time by applying a continuous concentration method, achieving reduction of the immersion time.
  • Preventing damage to the product and improve the yield by circulating the seasoning liquid without moving the product.
  • Improving the yield by recovering and reusing of seasoning liquid
  • Low-temperature concentration minimizes deterioration of seasoning liquid due to heat.
  • Improving the hygienic condition and working environment by performing a series of processes in a closed container without steam outflow.
  • Uniformity of product quality can be achieved by uniform infiltration of seasoning liquid into raw materials.
  • Fully automated operation provides labor saving.
