大阪ガスリキッド List of Products and Services

Utilizing the cold energy of liquid nitrogen produced by our company (-196℃), we can grind food without compromising quality in a nitrogen gas atmosphere and at freezing temperatures. We offer assistance in creating this high-quality powder as a contracted service. In physical property tests, we conducted "particle size distribution measurement" comparing the particle sizes of room temperature and low temperature ground products, as well as measurements of "functional components in the extract," "dispersion degree," and "photographic observation." In sensory tests, we evaluated "deliciousness" and "flavor" with a panel of 30 women in their 30s and 40s, who clearly recognized differences in a taste test. 【Physical Property Tests of Low-Temperature Ground Coffee】 ■ Particle Size Distribution Measurement ■ Measurement of Functional Components in the Extract ■ Measurement of Dispersion Degree ■ Photographic Observation *For more details, please refer to the PDF document or feel free to contact us.

• Liquid nitrogen related

Our website introduces the food grinding flow from raw materials to powdered food ingredients. Raw materials are fed into a freezer (raw material hopper). The fed raw materials are pre-cooled with liquid nitrogen inside the freezer. The raw materials are transported quantitatively using a screw feeder and ground to the desired particle size with a Linrex Mill (low-temperature freeze grinder). The powdered material lifted by a blower is collected in a cyclone and filled as a product. Please visit our website. 【Equipment Available】 ■ Linrex Mills: 4 units (2 large machines, 1 medium machine, 1 test machine) ■ Metal detectors: 2 units ■ X-ray inspection machine: 1 unit 【Certifications Obtained】 ■ FSSC22000 *For more details, please refer to the PDF document or feel free to contact us.

• Crusher/Mill

Our website introduces the low-temperature grinding center "Food Factory." By individualizing and separately air-conditioning the grinding rooms, we prevent cross-contamination. We implement various measures to prevent complex contamination, such as distinguishing between general areas and sanitary areas. We perform frozen grinding processing with a safe, secure, and highly efficient production system. Please take a look at our website. 【Features】 ■ Safe, secure, and highly efficient production system ■ Various measures to prevent complex contamination ■ Prevention of cross-contamination by individualizing and separately air-conditioning the grinding rooms ■ FSSC22000 certified ■ Contract factory dedicated to food ■ Grinding capacity from several tens of kg to 3 tons per batch *For more details, please refer to the PDF materials or feel free to contact us.

This document introduces the achievements of low-temperature grinding of almonds. Almonds contain a very high amount of oil, making it difficult to turn them into a powder at room temperature as they tend to become paste-like. However, if you leave it to us, we can process the oil into a fine powder. 【Almond Powder】 50% passing diameter: 7.262μm 90% passing diameter: 22.494μm *It has a texture similar to that of soybean flour. *If you would like a sample of almond powder, please feel free to contact us. *For more details, please refer to the PDF document or feel free to contact us.

On our website, we introduce Q&A regarding "super low temperature of liquid nitrogen," including the characteristics of low-temperature grinding, why we grind at low temperatures, and whether we can grind foods containing moisture and oil. We also provide a wealth of information on questions such as, "Can allergens be ground?" and "How is the grinder cleaned?" and "Can the raw materials be of any size?" Please be sure to visit our website. 【Content Highlights (Excerpt)】 ■Q. Why grind at low temperatures? ■Q. What are the characteristics of low-temperature grinding? ■Q. Can foods with high moisture and oil content be ground? ■Q. Can allergens be ground? ■Q. How is the grinder cleaned? *For more details, please refer to the PDF document or feel free to contact us.

• Fine grinding machine

On our website, we introduce examples of food grinding processing using the ultra-low temperatures of liquid nitrogen for heat-sensitive components. When grinding at room temperature, heat is generated, which causes the original flavors and aromas of the ingredients to dissipate, and the components can also be damaged. Grinding at low temperatures allows for the creation of fine powders without affecting the taste, aroma, or components. Please take a look at our website. 【Case Overview】 ■Challenge - When powdered, the taste, aroma, and heat-sensitive components are compromised. ■Result - By using liquid nitrogen and processing at low temperatures, we were able to maintain the taste, aroma, and heat-sensitive components. *For more details, please refer to the PDF document or feel free to contact us.

• Fine grinding machine

On our website, we introduce examples of grinding processing of food products containing a high amount of oil using the ultra-low temperatures of liquid nitrogen. Raw materials that contain a lot of oil, such as almonds, become crushed and are difficult to turn into fine powder when ground at room temperature. It is possible to maintain a powdered form at room temperature, regardless of whether the oil is liquid or solid, even when left standing. Please take a look at our website. 【Case Overview】 ■Challenge - Difficult to turn food raw materials with a high oil content into fine powder ■Result - Grinding processing was performed while freezing, resulting in food raw materials with high oil content being turned into fine powder *For more details, please refer to the PDF document or feel free to contact us.

• Fine grinding machine

On our website, we introduce examples of grinding processing of food products with high moisture content using the ultra-low temperatures of liquid nitrogen. Raw materials that contain a lot of moisture, such as fruits, cannot be crushed into fine powder at room temperature. By performing grinding processing while freezing, it is possible to turn moisture-rich food materials into fine powder. Please take a look at our website. 【Case Summary】 ■Challenge - It is difficult to create fine powder from food materials with high moisture content, such as fruits. ■Result - By performing grinding processing while completely freezing the moisture, moisture-rich food materials were turned into fine powder. *For more details, please refer to the PDF document or feel free to contact us.

• Fine grinding machine

Our pulverizer uses liquid nitrogen in a hammer crusher mill capable of fine grinding, allowing us to obtain a fine powder (average 10µm to 300µm) that maintains the unique flavors and aromas of food ingredients, as well as heat-sensitive components. By completely freezing moisture and oil with liquid nitrogen, it is possible to process food ingredients that are difficult to grind at room temperature. *Since there is no drying process, the moisture content of the raw materials does not change.

• Food ingredients (powder)

By using liquid nitrogen to freeze moisture and oil completely, it is possible to process food materials that are difficult to grind at room temperature into powder. Would you like to try contract processing at our FSSC22000 certified food factory? We also welcome requests for test grinding only! Our grinding machine uses a hammer crusher mill capable of fine grinding with liquid nitrogen, allowing us to obtain fine powders (average 10µm to 300µm) that maintain the unique flavors and aromas of food materials, as well as heat-sensitive components. We have three types of grinders with different processing capacities, so we can process from a few kilograms to several tons per day, tailored to your desired quantity. 【Features】 ■ By freezing the raw materials with liquid nitrogen, we can grind food materials that contain high levels of oil and moisture. * Unlike freeze-drying, there is no drying process, so the moisture content remains stable. ■ Grinding at temperatures below -100°C allows us to grind without damaging heat-sensitive components, aromas, or flavors. ■ By grinding in a nitrogen atmosphere, the product bags become nitrogen-rich, which helps suppress oxidation. ■ Due to the fine powder, dispersion in water is improved.
