ORIHIRO Material Co., Ltd.
About ORIHIRO Material
We have built our own production line and an integrated system that makes the best use of our know-how in each process, which is the key point from drying konjac raw potatoes to fine powder, compounding, quality inspection, and storage. We provide a stable supply of high-quality, high-purity mannan, which is indispensable for producing high-quality konjac products.
Konjac raw materials business / Manufacturing and sales of konjac raw material
Manufacture of konjac raw materials
In the primary processing, locally cultivated konjac potatoes are sorted by type or size and then washed. Then slice it to a thickness of about 2 to 3 mm and go to heat dryer to make dried "rough powder".
In the secondary processing, refinement processing is performed to extract glucomannan from dried rough powder. Next, pressure is applied to the rough powder to crush it, and polishing is repeated to remove impurities. Then, the viscosity of the extracted mannan is inspected to make the optimum blending. Products are inspected again, and those that do not meet the quality standard are reprocessed again.
From storage to shipping
Good quality products are stored in a cold warehouse so that the viscosity of Mannan is not compromised and shipped when an order is placed.
Factory / quality inspection
We are equipped with a state-of-the-art system developed in-house that can automatically adjust to the optimum drying temperature according to the amount of water evaporation from raw potatoes. We produce high-quality rough powder that has been sufficiently dried without impairing the characteristics of mannan.
We are efficiently producing high-purity glucomannan in a short time by developing our own crushing system that can automatically adjust the pressure applied to rough powder and production system that can automatically control the heat generated during polishing process.
High-purity glucomannan, which was refined according to the type and standard, is blended after undergoing strict product inspection (by type and viscosity) to produce high-quality refined powder with stable viscosity.
Based on various data related to konjac products, we carry out strict quality inspections, chemical analyzes, and safety evaluation.
Development of konjac products
Orihiro Material have developed "Timac Mannan", which cuts the odor peculiar to konjac, and "AF Mannan" which is dissolved in water and aseptically packaged in a gel form. A number of new initiatives are continuously underway, such as the development of foods with new texture, foods with functional claims using glucomannan, and foods for specified health uses.
