Latest technology applications
Due to its dramatic technological improvement, Osaka Gas Liquid is pleased to introduce new solutions using cryogenic and freezer grinding.
As a leading company in cryogenic and freezer grinding, we will continue to propose solutions that meet the needs of the market.
Liquid powdering technology
Drying frozen particles at low temperature makes it possible to turn raw materials into powder without heating.

Advantage of the liquid powdering technology
- Unheated processing
- Compared to heated drying methods, degradation and alteration of active ingredients due to heat can be significantly reduced.
- Porous
- Since fine air gaps are created in the powder, solubility and dispersibility are expected to be improved.
- Uniform components
- No component separation or concentration gradient occurs during freeze-drying, reducing component ununiformity.
Ultrafine grinding of plastics
Further pulverization in the cryogenic and freezer grinding technique, namely ultrafine grinding
with an average particle size of 10 μm or less, is now possible.
Further improvement of various powder properties, including fluidity, impregnability and particle size distribution, is expected.

Grinding of liquid crystal polymer (LCP)
It had been difficult to grind LCP because its molecular chains are oriented in one direction,
and when it is ground, it becomes fibrillated.
As a result of searching for a new grinder and technological development, we have succeeded in powdering LCP.
Grinding of various types of films
With the conventional method, films could not be ground because they stagnated inside the grinder,
which eventually caused an internal blockage.
However, we have made fine grinding possible through man-hour improvements and original ideas.
Expansion of accepted materials
- Water soluble materials
(PVOH, etc.) - Colored materials
(Black, gray, etc.)

Track record in grinding
Here are some of the materials that we have ground.
All are ground under the same conditions (machine conditions for finest quality);
however, the particle size varies depending on the material.
